-If you would like to have your module removed from pkg.go.dev, we recommend that you retract them, so that they can be removed from the go command and proxy.golang.org as well.

-Retracting a module version involves adding a retract directive to your go.mod file and publishing a new version. For example: https://github.com/jba/retract-demo/blob/main/go.mod#L5-L8

-### Proposal
-
-- **What is the proposed change?**
-- **Who does this proposal help, and why?**
-- **Please describe as precisely as possible the change to the language.**
-- **What would change in the language spec?**
-- **Please also describe the change informally, as in a class teaching Go.**
-- **Is this change backward compatible?**
-  - Breaking the Go 1 compatibility guarantee is a large cost and requires a large benefit.
-    Show example code before and after the change.
-  - **Before**
-  - **After**
-- **Orthogonality: how does this change interact or overlap with existing features?**
-- **Is the goal of this change a performance improvement?**
-  - **If so, what quantifiable improvement should we expect?**
-  - **How would we measure it?**
-
-### Costs
-
-- **Would this change make Go easier or harder to learn, and why?**
-- **What is the cost of this proposal? (Every language change has a cost).**
-- **How many tools (such as vet, gopls, gofmt, goimports, etc.) would be affected?**
-- **What is the compile time cost?**
-- **What is the run time cost?**
-- **Can you describe a possible implementation?**
-- **Do you have a prototype? (This is not required.)**

+<!--{
+	"title": "About the go command"
+}-->
+
+<p>The Go distribution includes a command, named
+"<code><a href="/cmd/go/">go</a></code>", that
+automates the downloading, building, installation, and testing of Go packages
+and commands.  This document talks about why we wrote a new command, what it
+is, what it's not, and how to use it.</p>
+
+<h2>Motivation</h2>
+
+<p>You might have seen early Go talks in which Rob Pike jokes that the idea
+for Go arose while waiting for a large Google server to compile.  That
+really was the motivation for Go: to build a language that worked well
+for building the large software that Google writes and runs. It was
+clear from the start that such a language must provide a way to
+express dependencies between code libraries clearly, hence the package
+grouping and the explicit import blocks.  It was also clear from the
+start that you might want arbitrary syntax for describing the code
+being imported; this is why import paths are string literals.</p>
+
+<p>An explicit goal for Go from the beginning was to be able to build Go
+code using only the information found in the source itself, not
+needing to write a makefile or one of the many modern replacements for
+makefiles.  If Go needed a configuration file to explain how to build
+your program, then Go would have failed.</p>
+
+<p>At first, there was no Go compiler, and the initial development
+focused on building one and then building libraries for it. For
+expedience, we postponed the automation of building Go code by using
+make and writing makefiles.  When compiling a single package involved
+multiple invocations of the Go compiler, we even used a program to
+write the makefiles for us.  You can find it if you dig through the
+repository history.</p>
+
+<p>The purpose of the new go command is our return to this ideal, that Go
+programs should compile without configuration or additional effort on
+the part of the developer beyond writing the necessary import
+statements.</p>
+
+<h2>Configuration versus convention</h2>
+
+<p>The way to achieve the simplicity of a configuration-free system is to
+establish conventions. The system works only to the extent that those conventions
+are followed. When we first launched Go, many people published packages that
+had to be installed in certain places, under certain names, using certain build
+tools, in order to be used. That's understandable: that's the way it works in
+most other languages. Over the last few years we consistently reminded people
+about the <code>goinstall</code> command
+(now replaced by <a href="/cmd/go/#hdr-Download_and_install_packages_and_dependencies"><code>go get</code></a>)
+and its conventions: first, that the import path is derived in a known way from
+the URL of the source code; second, that the place to store the sources in
+the local file system is derived in a known way from the import path; third,
+that each directory in a source tree corresponds to a single package; and
+fourth, that the package is built using only information in the source code.
+Today, the vast majority of packages follow these conventions.
+The Go ecosystem is simpler and more powerful as a result.</p>
+
+<p>We received many requests to allow a makefile in a package directory to
+provide just a little extra configuration beyond what's in the source code.
+But that would have introduced new rules. Because we did not accede to such
+requests, we were able to write the go command and eliminate our use of make
+or any other build system.</p>
+
+<p>It is important to understand that the go command is not a general
+build tool. It cannot be configured and it does not attempt to build
+anything but Go packages.  These are important simplifying
+assumptions: they simplify not only the implementation but also, more
+important, the use of the tool itself.</p>
+
+<h2>Go's conventions</h2>
+
+<p>The <code>go</code> command requires that code adheres to a few key,
+well-established conventions.</p>
+
+<p>First, the import path is derived in an known way from the URL of the
+source code.  For Bitbucket, GitHub, Google Code, and Launchpad, the
+root directory of the repository is identified by the repository's
+main URL, without the <code>http://</code> prefix.  Subdirectories are named by
+adding to that path.
+For example, the Go example programs are obtained by running</p>
+
+<pre>
+git clone https://github.com/golang/example
+</pre>
+
+<p>and thus the import path for the root directory of that repository is
+"<code>github.com/golang/example</code>".
+The <a href="https://godoc.org/github.com/golang/example/stringutil">stringutil</a>
+package is stored in a subdirectory, so its import path is
+"<code>github.com/golang/example/stringutil</code>".</p>
+
+<p>These paths are on the long side, but in exchange we get an
+automatically managed name space for import paths and the ability for
+a tool like the go command to look at an unfamiliar import path and
+deduce where to obtain the source code.</p>
+
+<p>Second, the place to store sources in the local file system is derived
+in a known way from the import path, specifically
+<code>$GOPATH/src/&lt;import-path&gt;</code>.
+If unset, <code>$GOPATH</code> defaults to a subdirectory
+named <code>go</code> in the user's home directory.
+If <code>$GOPATH</code> is set to a list of paths, the go command tries
+<code>&lt;dir&gt;/src/&lt;import-path&gt;</code> for each of the directories in
+that list.
+</p>
+
+<p>Each of those trees contains, by convention, a top-level directory named
+"<code>bin</code>", for holding compiled executables, and a top-level directory
+named "<code>pkg</code>", for holding compiled packages that can be imported,
+and the "<code>src</code>" directory, for holding package source files.
+Imposing this structure lets us keep each of these directory trees
+self-contained: the compiled form and the sources are always near each
+other.</p>
+
+<p>These naming conventions also let us work in the reverse direction,
+from a directory name to its import path. This mapping is important
+for many of the go command's subcommands, as we'll see below.</p>
+
+<p>Third, each directory in a source tree corresponds to a single
+package. By restricting a directory to a single package, we don't have
+to create hybrid import paths that specify first the directory and
+then the package within that directory.  Also, most file management
+tools and UIs work on  directories as fundamental units.  Tying the
+fundamental Go unit&mdash;the package&mdash;to file system structure means
+that file system tools become Go package tools.  Copying, moving, or
+deleting a package corresponds to copying, moving, or deleting a
+directory.</p>
+
+<p>Fourth, each package is built using only the information present in
+the source files.  This makes it much more likely that the tool will
+be able to adapt to changing build environments and conditions. For
+example, if we allowed extra configuration such as compiler flags or
+command line recipes, then that configuration would need to be updated
+each time the build tools changed; it would also be inherently tied
+to the use of a specific tool chain.</p>
+
+<h2>Getting started with the go command</h2>
+
+<p>Finally, a quick tour of how to use the go command.
+As mentioned above, the default <code>$GOPATH</code> on Unix is <code>$HOME/go</code>.
+We'll store our programs there.
+To use a different location, you can set <code>$GOPATH</code>;
+see <a href="/doc/code.html">How to Write Go Code</a> for details.
+
+<p>We first add some source code.  Suppose we want to use
+the indexing library from the codesearch project along with a left-leaning
+red-black tree.  We can install both with the "<code>go get</code>"
+subcommand:</p>
+
+<pre>
+$ go get github.com/google/codesearch/index
+$ go get github.com/petar/GoLLRB/llrb
+$
+</pre>
+
+<p>Both of these projects are now downloaded and installed into <code>$HOME/go</code>,
+which contains the two directories
+<code>src/github.com/google/codesearch/index/</code> and
+<code>src/github.com/petar/GoLLRB/llrb/</code>, along with the compiled
+packages (in <code>pkg/</code>) for those libraries and their dependencies.</p>
+
+<p>Because we used version control systems (Mercurial and Git) to check
+out the sources, the source tree also contains the other files in the
+corresponding repositories, such as related packages. The "<code>go list</code>"
+subcommand lists the import paths corresponding to its arguments, and
+the pattern "<code>./...</code>" means start in the current directory
+("<code>./</code>") and find all packages below that directory
+("<code>...</code>"):</p>
+
+<pre>
+$ cd $HOME/go/src
+$ go list ./...
+github.com/google/codesearch/cmd/cgrep
+github.com/google/codesearch/cmd/cindex
+github.com/google/codesearch/cmd/csearch
+github.com/google/codesearch/index
+github.com/google/codesearch/regexp
+github.com/google/codesearch/sparse
+github.com/petar/GoLLRB/example
+github.com/petar/GoLLRB/llrb
+$
+</pre>
+
+<p>We can also test those packages:</p>
+
+<pre>
+$ go test ./...
+?   	github.com/google/codesearch/cmd/cgrep	[no test files]
+?   	github.com/google/codesearch/cmd/cindex	[no test files]
+?   	github.com/google/codesearch/cmd/csearch	[no test files]
+ok  	github.com/google/codesearch/index	0.203s
+ok  	github.com/google/codesearch/regexp	0.017s
+?   	github.com/google/codesearch/sparse	[no test files]
+?       github.com/petar/GoLLRB/example          [no test files]
+ok      github.com/petar/GoLLRB/llrb             0.231s
+$
+</pre>
+
+<p>If a go subcommand is invoked with no paths listed, it operates on the
+current directory:</p>
+
+<pre>
+$ cd github.com/google/codesearch/regexp
+$ go list
+github.com/google/codesearch/regexp
+$ go test -v
+=== RUN   TestNstateEnc
+--- PASS: TestNstateEnc (0.00s)
+=== RUN   TestMatch
+--- PASS: TestMatch (0.00s)
+=== RUN   TestGrep
+--- PASS: TestGrep (0.00s)
+PASS
+ok  	github.com/google/codesearch/regexp	0.018s
+$ go install
+$
+</pre>
+
+<p>That "<code>go install</code>" subcommand installs the latest copy of the
+package into the pkg directory. Because the go command can analyze the
+dependency graph, "<code>go install</code>" also installs any packages that
+this package imports but that are out of date, recursively.</p>
+
+<p>Notice that "<code>go install</code>" was able to determine the name of the
+import path for the package in the current directory, because of the convention
+for directory naming.  It would be a little more convenient if we could pick
+the name of the directory where we kept source code, and we probably wouldn't
+pick such a long name, but that ability would require additional configuration
+and complexity in the tool. Typing an extra directory name or two is a small
+price to pay for the increased simplicity and power.</p>
+
+<h2>Limitations</h2>

+<p>As mentioned above, the go command is not a general-purpose build
+tool.
+In particular, it does not have any facility for generating Go
+source files <em>during</em> a build, although it does provide
+<a href="/cmd/go/#hdr-Generate_Go_files_by_processing_source"><code>go</code>
+<code>generate</code></a>,
+which can automate the creation of Go files <em>before</em> the build.
+For more advanced build setups, you may need to write a
+makefile (or a configuration file for the build tool of your choice)
+to run whatever tool creates the Go files and then check those generated source files
+into your repository. This is more work for you, the package author,
+but it is significantly less work for your users, who can use
+"<code>go get</code>" without needing to obtain and build
+any additional tools.</p>

+	"Template": true
+}-->
+
+<h2 id="Introduction">Introduction</h2>
+
+<p>
+Data races are among the most common and hardest to debug types of bugs in concurrent systems.
+A data race occurs when two goroutines access the same variable concurrently and at least one of the accesses is a write.
+See the <a href="/ref/mem/">The Go Memory Model</a> for details.
+</p>
+
+<p>
+Here is an example of a data race that can lead to crashes and memory corruption:
+</p>
+
+<pre>
+func main() {
+	c := make(chan bool)
+	m := make(map[string]string)
+	go func() {
+		m["1"] = "a" // First conflicting access.
+		c &lt;- true
+	}()
+	m["2"] = "b" // Second conflicting access.
+	&lt;-c
+	for k, v := range m {
+		fmt.Println(k, v)
+	}
+}
+</pre>
+
+<h2 id="Usage">Usage</h2>
+
+<p>
+To help diagnose such bugs, Go includes a built-in data race detector.
+To use it, add the <code>-race</code> flag to the go command:
+</p>
+
+<pre>
+$ go test -race mypkg    // to test the package
+$ go run -race mysrc.go  // to run the source file
+$ go build -race mycmd   // to build the command
+$ go install -race mypkg // to install the package
+</pre>
+
+<h2 id="Report_Format">Report Format</h2>
+
+<p>
+When the race detector finds a data race in the program, it prints a report.
+The report contains stack traces for conflicting accesses, as well as stacks where the involved goroutines were created.
+Here is an example:
+</p>
+
+<pre>
+WARNING: DATA RACE
+Read by goroutine 185:
+  net.(*pollServer).AddFD()
+      src/net/fd_unix.go:89 +0x398

+      src/testing/testing.go:301 +0xe8
+</pre>
+
+<h2 id="Options">Options</h2>
+
+<p>
+The <code>GORACE</code> environment variable sets race detector options.
+The format is:
+</p>
+
+<pre>
+GORACE="option1=val1 option2=val2"
+</pre>
+
+<p>
+The options are:
+</p>
+
+<ul>
+<li>
+<code>log_path</code> (default <code>stderr</code>): The race detector writes
+its report to a file named <code>log_path.<em>pid</em></code>.
+The special names <code>stdout</code>
+and <code>stderr</code> cause reports to be written to standard output and
+standard error, respectively.
+</li>
+
+<li>
+<code>exitcode</code> (default <code>66</code>): The exit status to use when
+exiting after a detected race.
+</li>
+
+<li>
+<code>strip_path_prefix</code> (default <code>""</code>): Strip this prefix
+from all reported file paths, to make reports more concise.
+</li>
+
+<li>
+<code>history_size</code> (default <code>1</code>): The per-goroutine memory
+access history is <code>32K * 2**history_size elements</code>.
+Increasing this value can avoid a "failed to restore the stack" error in reports, at the
+cost of increased memory usage.
+</li>
+
+<li>
+<code>halt_on_error</code> (default <code>0</code>): Controls whether the program
+exits after reporting first data race.
+</li>
+</ul>
+
+<p>
+Example:
+</p>
+
+<pre>
+$ GORACE="log_path=/tmp/race/report strip_path_prefix=/my/go/sources/" go test -race
+</pre>
+
+<h2 id="Excluding_Tests">Excluding Tests</h2>
+
+<p>
+When you build with <code>-race</code> flag, the <code>go</code> command defines additional
+<a href="/pkg/go/build/#hdr-Build_Constraints">build tag</a> <code>race</code>.
+You can use the tag to exclude some code and tests when running the race detector.
+Some examples:
+</p>
+
+<pre>
+// +build !race
+
+package foo
+
+// The test contains a data race. See issue 123.
+func TestFoo(t *testing.T) {
+	// ...
+}
+
+// The test fails under the race detector due to timeouts.
+func TestBar(t *testing.T) {
+	// ...
+}
+
+// The test takes too long under the race detector.
+func TestBaz(t *testing.T) {
+	// ...
+}
+</pre>
+
+<h2 id="How_To_Use">How To Use</h2>
+
+<p>
+To start, run your tests using the race detector (<code>go test -race</code>).
+The race detector only finds races that happen at runtime, so it can't find
+races in code paths that are not executed.
+If your tests have incomplete coverage,
+you may find more races by running a binary built with <code>-race</code> under a realistic
+workload.
+</p>
+
+<h2 id="Typical_Data_Races">Typical Data Races</h2>
+
+<p>
+Here are some typical data races.  All of them can be detected with the race detector.
+</p>
+
+<h3 id="Race_on_loop_counter">Race on loop counter</h3>
+
+<pre>
+func main() {
+	var wg sync.WaitGroup
+	wg.Add(5)
+	for i := 0; i < 5; i++ {
+		go func() {
+			fmt.Println(i) // Not the 'i' you are looking for.
+			wg.Done()
+		}()
+	}
+	wg.Wait()
+}
+</pre>
+
+<p>
+The variable <code>i</code> in the function literal is the same variable used by the loop, so
+the read in the goroutine races with the loop increment.
+(This program typically prints 55555, not 01234.)
+The program can be fixed by making a copy of the variable:
+</p>
+
+<pre>
+func main() {
+	var wg sync.WaitGroup
+	wg.Add(5)
+	for i := 0; i < 5; i++ {
+		go func(j int) {
+			fmt.Println(j) // Good. Read local copy of the loop counter.
+			wg.Done()
+		}(i)
+	}
+	wg.Wait()
+}
+</pre>
+
+<h3 id="Accidentally_shared_variable">Accidentally shared variable</h3>
+
+<pre>
+// ParallelWrite writes data to file1 and file2, returns the errors.
+func ParallelWrite(data []byte) chan error {
+	res := make(chan error, 2)
+	f1, err := os.Create("file1")
+	if err != nil {
+		res &lt;- err
+	} else {
+		go func() {
+			// This err is shared with the main goroutine,
+			// so the write races with the write below.
+			_, err = f1.Write(data)
+			res &lt;- err
+			f1.Close()
+		}()
+	}
+	f2, err := os.Create("file2") // The second conflicting write to err.
+	if err != nil {
+		res &lt;- err
+	} else {
+		go func() {
+			_, err = f2.Write(data)
+			res &lt;- err
+			f2.Close()
+		}()
+	}
+	return res
+}
+</pre>
+
+<p>
+The fix is to introduce new variables in the goroutines (note the use of <code>:=</code>):
+</p>
+
+<pre>
+			...
+			_, err := f1.Write(data)
+			...
+			_, err := f2.Write(data)
+			...
+</pre>
+
+<h3 id="Unprotected_global_variable">Unprotected global variable</h3>
+
+<p>
+If the following code is called from several goroutines, it leads to races on the <code>service</code> map.
+Concurrent reads and writes of the same map are not safe:
+</p>
+
+<pre>
+var service map[string]net.Addr
+
+func RegisterService(name string, addr net.Addr) {
+	service[name] = addr
+}
+
+func LookupService(name string) net.Addr {
+	return service[name]
+}
+</pre>
+
+<p>
+To make the code safe, protect the accesses with a mutex:
+</p>
+
+<pre>
+var (
+	service   map[string]net.Addr
+	serviceMu sync.Mutex
+)
+
+func RegisterService(name string, addr net.Addr) {
+	serviceMu.Lock()
+	defer serviceMu.Unlock()
+	service[name] = addr
+}
+
+func LookupService(name string) net.Addr {
+	serviceMu.Lock()
+	defer serviceMu.Unlock()
+	return service[name]
+}
+</pre>
+
+<h3 id="Primitive_unprotected_variable">Primitive unprotected variable</h3>
+
+<p>
+Data races can happen on variables of primitive types as well (<code>bool</code>, <code>int</code>, <code>int64</code>, etc.),
+as in this example:
+</p>
+
+<pre>
+type Watchdog struct{ last int64 }
+
+func (w *Watchdog) KeepAlive() {
+	w.last = time.Now().UnixNano() // First conflicting access.
+}
+
+func (w *Watchdog) Start() {
+	go func() {
+		for {
+			time.Sleep(time.Second)
+			// Second conflicting access.
+			if w.last < time.Now().Add(-10*time.Second).UnixNano() {
+				fmt.Println("No keepalives for 10 seconds. Dying.")
+				os.Exit(1)
+			}
+		}
+	}()
+}
+</pre>
+
+<p>
+Even such "innocent" data races can lead to hard-to-debug problems caused by
+non-atomicity of the memory accesses,
+interference with compiler optimizations,
+or reordering issues accessing processor memory .
+</p>
+
+<p>
+A typical fix for this race is to use a channel or a mutex.
+To preserve the lock-free behavior, one can also use the
+<a href="/pkg/sync/atomic/"><code>sync/atomic</code></a> package.
+</p>
+
+<pre>
+type Watchdog struct{ last int64 }
+
+func (w *Watchdog) KeepAlive() {
+	atomic.StoreInt64(&amp;w.last, time.Now().UnixNano())
+}
+
+func (w *Watchdog) Start() {
+	go func() {
+		for {
+			time.Sleep(time.Second)
+			if atomic.LoadInt64(&amp;w.last) < time.Now().Add(-10*time.Second).UnixNano() {
+				fmt.Println("No keepalives for 10 seconds. Dying.")
+				os.Exit(1)
+			}
+		}
+	}()
+}
+</pre>
+
+<h2 id="Supported_Systems">Supported Systems</h2>
+
+<p>
+The race detector runs on <code>darwin/amd64</code>, <code>freebsd/amd64</code>,
+<code>linux/amd64</code>, and <code>windows/amd64</code>.
+</p>
+
+<h2 id="Runtime_Overheads">Runtime Overhead</h2>
+
+<p>
+The cost of race detection varies by program, but for a typical program, memory
+usage may increase by 5-10x and execution time by 2-20x.

+</p>
+<ul>
+<li>Programming experience</li>
+<li>Understanding of basic web technologies (HTTP, HTML)</li>
+<li>Some UNIX/DOS command-line knowledge</li>
+</ul>
+
+<h2>Getting Started</h2>
+
+<p>
+At present, you need to have a FreeBSD, Linux, OS X, or Windows machine to run Go.
+We will use <code>$</code> to represent the command prompt.
+</p>
+
+<p>
+Install Go (see the <a href="/doc/install">Installation Instructions</a>).
+</p>
+
+<p>
+Make a new directory for this tutorial inside your <code>GOPATH</code> and cd to it:
+</p>
+
+<pre>
+$ mkdir gowiki
+$ cd gowiki
+</pre>
+
+<p>
+Create a file named <code>wiki.go</code>, open it in your favorite editor, and
+add the following lines:
+</p>
+
+<pre>
+package main
+
+import (
+	"fmt"
+	"io/ioutil"
+)
+</pre>
+
+<p>
+We import the <code>fmt</code> and <code>ioutil</code> packages from the Go
+standard library. Later, as we implement additional functionality, we will
+add more packages to this <code>import</code> declaration.
+</p>
+
+<h2>Data Structures</h2>
+
+<p>
+Let's start by defining the data structures. A wiki consists of a series of
+interconnected pages, each of which has a title and a body (the page content).
+Here, we define <code>Page</code> as a struct with two fields representing
+the title and body.
+</p>
+
+{{code "doc/articles/wiki/part1.go" `/^type Page/` `/}/`}}
+
+<p>
+The type <code>[]byte</code> means "a <code>byte</code> slice".
+(See <a href="/doc/articles/slices_usage_and_internals.html">Slices: usage and
+internals</a> for more on slices.)
+The <code>Body</code> element is a <code>[]byte</code> rather than
+<code>string</code> because that is the type expected by the <code>io</code>
+libraries we will use, as you'll see below.
+</p>
+
+<p>
+The <code>Page</code> struct describes how page data will be stored in memory.
+But what about persistent storage? We can address that by creating a
+<code>save</code> method on <code>Page</code>:
+</p>
+
+{{code "doc/articles/wiki/part1.go" `/^func.*Page.*save/` `/}/`}}
+
+<p>
+This method's signature reads: "This is a method named <code>save</code> that
+takes as its receiver <code>p</code>, a pointer to <code>Page</code> . It takes
+no parameters, and returns a value of type <code>error</code>."
+</p>
+
+<p>
+This method will save the <code>Page</code>'s <code>Body</code> to a text
+file. For simplicity, we will use the <code>Title</code> as the file name.
+</p>
+
+<p>
+The <code>save</code> method returns an <code>error</code> value because
+that is the return type of <code>WriteFile</code> (a standard library function
+that writes a byte slice to a file).  The <code>save</code> method returns the
+error value, to let the application handle it should anything go wrong while
+writing the file.  If all goes well, <code>Page.save()</code> will return
+<code>nil</code> (the zero-value for pointers, interfaces, and some other
+types).
+</p>
+
+<p>
+The octal integer literal <code>0600</code>, passed as the third parameter to
+<code>WriteFile</code>, indicates that the file should be created with
+read-write permissions for the current user only. (See the Unix man page
+<code>open(2)</code> for details.)
+</p>
+
+<p>
+In addition to saving pages, we will want to load pages, too:
+</p>
+
+{{code "doc/articles/wiki/part1-noerror.go" `/^func loadPage/` `/^}/`}}
+
+<p>
+The function <code>loadPage</code> constructs the file name from the title
+parameter, reads the file's contents into a new variable <code>body</code>, and
+returns a pointer to a <code>Page</code> literal constructed with the proper
+title and body values.
+</p>
+
+<p>
+Functions can return multiple values. The standard library function
+<code>io.ReadFile</code> returns <code>[]byte</code> and <code>error</code>.
+In <code>loadPage</code>, error isn't being handled yet; the "blank identifier"
+represented by the underscore (<code>_</code>) symbol is used to throw away the
+error return value (in essence, assigning the value to nothing).
+</p>
+
+<p>
+But what happens if <code>ReadFile</code> encounters an error?  For example,
+the file might not exist. We should not ignore such errors.  Let's modify the
+function to return <code>*Page</code> and <code>error</code>.
+</p>
+
+{{code "doc/articles/wiki/part1.go" `/^func loadPage/` `/^}/`}}
+
+<p>
+Callers of this function can now check the second parameter; if it is
+<code>nil</code> then it has successfully loaded a Page. If not, it will be an
+<code>error</code> that can be handled by the caller (see the
+<a href="/ref/spec#Errors">language specification</a> for details).
+</p>
+
+<p>
+At this point we have a simple data structure and the ability to save to and
+load from a file. Let's write a <code>main</code> function to test what we've
+written:
+</p>
+
+{{code "doc/articles/wiki/part1.go" `/^func main/` `/^}/`}}
+
+<p>
+After compiling and executing this code, a file named <code>TestPage.txt</code>
+would be created, containing the contents of <code>p1</code>. The file would
+then be read into the struct <code>p2</code>, and its <code>Body</code> element
+printed to the screen.
+</p>
+
+<p>
+You can compile and run the program like this:
+</p>
+
+<pre>
+$ go build wiki.go
+$ ./wiki
+This is a sample page.
+</pre>
+
+<p>
+(If you're using Windows you must type "<code>wiki</code>" without the
+"<code>./</code>" to run the program.)
+</p>
+
+<p>
+<a href="part1.go">Click here to view the code we've written so far.</a>
+</p>
+
+<h2>Introducing the <code>net/http</code> package (an interlude)</h2>
+
+<p>
+Here's a full working example of a simple web server:
+</p>
+
+{{code "doc/articles/wiki/http-sample.go"}}
+
+<p>
+The <code>main</code> function begins with a call to
+<code>http.HandleFunc</code>, which tells the <code>http</code> package to
+handle all requests to the web root (<code>"/"</code>) with
+<code>handler</code>.
+</p>
+
+<p>
+It then calls <code>http.ListenAndServe</code>, specifying that it should
+listen on port 8080 on any interface (<code>":8080"</code>). (Don't
+worry about its second parameter, <code>nil</code>, for now.)
+This function will block until the program is terminated.
+</p>
+
+<p>
+The function <code>handler</code> is of the type <code>http.HandlerFunc</code>.
+It takes an <code>http.ResponseWriter</code> and an <code>http.Request</code> as
+its arguments.
+</p>
+
+<p>
+An <code>http.ResponseWriter</code> value assembles the HTTP server's response; by writing
+to it, we send data to the HTTP client.
+</p>
+
+<p>
+An <code>http.Request</code> is a data structure that represents the client
+HTTP request. <code>r.URL.Path</code> is the path component
+of the request URL. The trailing <code>[1:]</code> means
+"create a sub-slice of <code>Path</code> from the 1st character to the end."
+This drops the leading "/" from the path name.
+</p>
+
+<p>
+If you run this program and access the URL:
+</p>
+<pre>http://localhost:8080/monkeys</pre>
+<p>
+the program would present a page containing:
+</p>
+<pre>Hi there, I love monkeys!</pre>
+
+<h2>Using <code>net/http</code> to serve wiki pages</h2>
+
+<p>
+To use the <code>net/http</code> package, it must be imported:
+</p>
+
+<pre>
+import (
+	"fmt"
+	"io/ioutil"
+	<b>"net/http"</b>
+)
+</pre>
+
+<p>
+Let's create a handler, <code>viewHandler</code> that will allow users to
+view a wiki page. It will handle URLs prefixed with "/view/".
+</p>
+
+{{code "doc/articles/wiki/part2.go" `/^func viewHandler/` `/^}/`}}
+
+<p>
+First, this function extracts the page title from <code>r.URL.Path</code>,
+the path component of the request URL.
+The <code>Path</code> is re-sliced with <code>[len("/view/"):]</code> to drop
+the leading <code>"/view/"</code> component of the request path.
+This is because the path will invariably begin with <code>"/view/"</code>,
+which is not part of the page's title.
+</p>
+
+<p>
+The function then loads the page data, formats the page with a string of simple
+HTML, and writes it to <code>w</code>, the <code>http.ResponseWriter</code>.
+</p>
+
+<p>
+Again, note the use of <code>_</code> to ignore the <code>error</code>
+return value from <code>loadPage</code>. This is done here for simplicity
+and generally considered bad practice. We will attend to this later.
+</p>
+
+<p>
+To use this handler, we rewrite our <code>main</code> function to
+initialize <code>http</code> using the <code>viewHandler</code> to handle
+any requests under the path <code>/view/</code>.
+</p>
+
+{{code "doc/articles/wiki/part2.go" `/^func main/` `/^}/`}}
+
+<p>
+<a href="part2.go">Click here to view the code we've written so far.</a>
+</p>
+
+<p>
+Let's create some page data (as <code>test.txt</code>), compile our code, and
+try serving a wiki page.
+</p>
+
+<p>
+Open <code>test.txt</code> file in your editor, and save the string "Hello world" (without quotes)
+in it.
+</p>
+
+<pre>
+$ go build wiki.go
+$ ./wiki
+</pre>
+
+<p>
+(If you're using Windows you must type "<code>wiki</code>" without the
+"<code>./</code>" to run the program.)
+</p>
+
+<p>
+With this web server running, a visit to <code><a
+href="http://localhost:8080/view/test">http://localhost:8080/view/test</a></code>
+should show a page titled "test" containing the words "Hello world".
+</p>
+
+<h2>Editing Pages</h2>
+
+<p>
+A wiki is not a wiki without the ability to edit pages. Let's create two new
+handlers: one named <code>editHandler</code> to display an 'edit page' form,
+and the other named <code>saveHandler</code> to save the data entered via the
+form.
+</p>
+
+<p>
+First, we add them to <code>main()</code>:
+</p>
+
+{{code "doc/articles/wiki/final-noclosure.go" `/^func main/` `/^}/`}}
+
+<p>
+The function <code>editHandler</code> loads the page
+(or, if it doesn't exist, create an empty <code>Page</code> struct),
+and displays an HTML form.
+</p>
+
+{{code "doc/articles/wiki/notemplate.go" `/^func editHandler/` `/^}/`}}
+
+<p>
+This function will work fine, but all that hard-coded HTML is ugly.
+Of course, there is a better way.
+</p>
+
+<h2>The <code>html/template</code> package</h2>
+
+<p>
+The <code>html/template</code> package is part of the Go standard library.
+We can use <code>html/template</code> to keep the HTML in a separate file,
+allowing us to change the layout of our edit page without modifying the
+underlying Go code.
+</p>
+
+<p>
+First, we must add <code>html/template</code> to the list of imports. We
+also won't be using <code>fmt</code> anymore, so we have to remove that.
+</p>
+
+<pre>
+import (
+	<b>"html/template"</b>
+	"io/ioutil"
+	"net/http"
+)
+</pre>
+
+<p>
+Let's create a template file containing the HTML form.
+Open a new file named <code>edit.html</code>, and add the following lines:
+</p>
+
+{{code "doc/articles/wiki/edit.html"}}
+
+<p>
+Modify <code>editHandler</code> to use the template, instead of the hard-coded
+HTML:
+</p>
+
+{{code "doc/articles/wiki/final-noerror.go" `/^func editHandler/` `/^}/`}}
+
+<p>
+The function <code>template.ParseFiles</code> will read the contents of
+<code>edit.html</code> and return a <code>*template.Template</code>.
+</p>
+
+<p>
+The method <code>t.Execute</code> executes the template, writing the
+generated HTML to the <code>http.ResponseWriter</code>.
+The <code>.Title</code> and <code>.Body</code> dotted identifiers refer to
+<code>p.Title</code> and <code>p.Body</code>.
+</p>
+
+<p>
+Template directives are enclosed in double curly braces.
+The <code>printf "%s" .Body</code> instruction is a function call
+that outputs <code>.Body</code> as a string instead of a stream of bytes,
+the same as a call to <code>fmt.Printf</code>.
+The <code>html/template</code> package helps guarantee that only safe and
+correct-looking HTML is generated by template actions. For instance, it
+automatically escapes any greater than sign (<code>&gt;</code>), replacing it
+with <code>&amp;gt;</code>, to make sure user data does not corrupt the form
+HTML.
+</p>
+
+<p>
+Since we're working with templates now, let's create a template for our
+<code>viewHandler</code> called <code>view.html</code>:
+</p>
+
+{{code "doc/articles/wiki/view.html"}}
+
+<p>
+Modify <code>viewHandler</code> accordingly:
+</p>
+
+{{code "doc/articles/wiki/final-noerror.go" `/^func viewHandler/` `/^}/`}}
+
+<p>
+Notice that we've used almost exactly the same templating code in both
+handlers. Let's remove this duplication by moving the templating code
+to its own function:
+</p>
+
+{{code "doc/articles/wiki/final-template.go" `/^func renderTemplate/` `/^}/`}}
+
+<p>
+And modify the handlers to use that function:
+</p>
+
+{{code "doc/articles/wiki/final-template.go" `/^func viewHandler/` `/^}/`}}
+{{code "doc/articles/wiki/final-template.go" `/^func editHandler/` `/^}/`}}
+
+<p>
+If we comment out the registration of our unimplemented save handler in
+<code>main</code>, we can once again build and test our program.
+<a href="part3.go">Click here to view the code we've written so far.</a>
+</p>
+
+<h2>Handling non-existent pages</h2>
+
+<p>
+What if you visit <a href="http://localhost:8080/view/APageThatDoesntExist">
+<code>/view/APageThatDoesntExist</code></a>? You'll see a page containing
+HTML. This is because it ignores the error return value from
+<code>loadPage</code> and continues to try and fill out the template
+with no data. Instead, if the requested Page doesn't exist, it should
+redirect the client to the edit Page so the content may be created:
+</p>
+
+{{code "doc/articles/wiki/part3-errorhandling.go" `/^func viewHandler/` `/^}/`}}
+
+<p>
+The <code>http.Redirect</code> function adds an HTTP status code of
+<code>http.StatusFound</code> (302) and a <code>Location</code>
+header to the HTTP response.
+</p>
+
+<h2>Saving Pages</h2>
+
+<p>
+The function <code>saveHandler</code> will handle the submission of forms
+located on the edit pages. After uncommenting the related line in
+<code>main</code>, let's implement the handler:
+</p>
+
+{{code "doc/articles/wiki/final-template.go" `/^func saveHandler/` `/^}/`}}
+
+<p>
+The page title (provided in the URL) and the form's only field,
+<code>Body</code>, are stored in a new <code>Page</code>.
+The <code>save()</code> method is then called to write the data to a file,
+and the client is redirected to the <code>/view/</code> page.
+</p>
+
+<p>
+The value returned by <code>FormValue</code> is of type <code>string</code>.
+We must convert that value to <code>[]byte</code> before it will fit into
+the <code>Page</code> struct. We use <code>[]byte(body)</code> to perform
+the conversion.
+</p>
+
+<h2>Error handling</h2>
+
+<p>
+There are several places in our program where errors are being ignored.  This
+is bad practice, not least because when an error does occur the program will
+have unintended behavior. A better solution is to handle the errors and return
+an error message to the user. That way if something does go wrong, the server
+will function exactly how we want and the user can be notified.
+</p>
+
+<p>
+First, let's handle the errors in <code>renderTemplate</code>:
+</p>
+
+{{code "doc/articles/wiki/final-parsetemplate.go" `/^func renderTemplate/` `/^}/`}}
+
+<p>
+The <code>http.Error</code> function sends a specified HTTP response code
+(in this case "Internal Server Error") and error message.
+Already the decision to put this in a separate function is paying off.
+</p>
+
+<p>
+Now let's fix up <code>saveHandler</code>:
+</p>
+
+{{code "doc/articles/wiki/part3-errorhandling.go" `/^func saveHandler/` `/^}/`}}
+
+<p>
+Any errors that occur during <code>p.save()</code> will be reported
+to the user.
+</p>
+
+<h2>Template caching</h2>
+
+<p>
+There is an inefficiency in this code: <code>renderTemplate</code> calls
+<code>ParseFiles</code> every time a page is rendered.
+A better approach would be to call <code>ParseFiles</code> once at program
+initialization, parsing all templates into a single <code>*Template</code>.
+Then we can use the
+<a href="/pkg/html/template/#Template.ExecuteTemplate"><code>ExecuteTemplate</code></a>
+method to render a specific template.
+</p>
+
+<p>
+First we create a global variable named <code>templates</code>, and initialize
+it with <code>ParseFiles</code>.
+</p>
+
+{{code "doc/articles/wiki/final.go" `/var templates/`}}
+
+<p>
+The function <code>template.Must</code> is a convenience wrapper that panics
+when passed a non-nil <code>error</code> value, and otherwise returns the
+<code>*Template</code> unaltered. A panic is appropriate here; if the templates
+can't be loaded the only sensible thing to do is exit the program.
+</p>
+
+<p>
+The <code>ParseFiles</code> function takes any number of string arguments that
+identify our template files, and parses those files into templates that are
+named after the base file name. If we were to add more templates to our
+program, we would add their names to the <code>ParseFiles</code> call's
+arguments.
+</p>
+
+<p>
+We then modify the <code>renderTemplate</code> function to call the
+<code>templates.ExecuteTemplate</code> method with the name of the appropriate
+template:
+</p>
+
+{{code "doc/articles/wiki/final.go" `/func renderTemplate/` `/^}/`}}
+
+<p>
+Note that the template name is the template file name, so we must
+append <code>".html"</code> to the <code>tmpl</code> argument.
+</p>
+
+<h2>Validation</h2>
+
+<p>
+As you may have observed, this program has a serious security flaw: a user
+can supply an arbitrary path to be read/written on the server. To mitigate
+this, we can write a function to validate the title with a regular expression.
+</p>
+
+<p>
+First, add <code>"regexp"</code> to the <code>import</code> list.
+Then we can create a global variable to store our validation 
+expression:
+</p>
+
+{{code "doc/articles/wiki/final-noclosure.go" `/^var validPath/`}}
+
+<p>
+The function <code>regexp.MustCompile</code> will parse and compile the
+regular expression, and return a <code>regexp.Regexp</code>.
+<code>MustCompile</code> is distinct from <code>Compile</code> in that it will
+panic if the expression compilation fails, while <code>Compile</code> returns
+an <code>error</code> as a second parameter.
+</p>
+
+<p>
+Now, let's write a function that uses the <code>validPath</code>
+expression to validate path and extract the page title:
+</p>
+
+{{code "doc/articles/wiki/final-noclosure.go" `/func getTitle/` `/^}/`}}
+
+<p>
+If the title is valid, it will be returned along with a <code>nil</code>
+error value. If the title is invalid, the function will write a
+"404 Not Found" error to the HTTP connection, and return an error to the
+handler. To create a new error, we have to import the <code>errors</code>
+package.
+</p>
+
+<p>
+Let's put a call to <code>getTitle</code> in each of the handlers:
+</p>
+
+{{code "doc/articles/wiki/final-noclosure.go" `/^func viewHandler/` `/^}/`}}
+{{code "doc/articles/wiki/final-noclosure.go" `/^func editHandler/` `/^}/`}}
+{{code "doc/articles/wiki/final-noclosure.go" `/^func saveHandler/` `/^}/`}}
+
+<h2>Introducing Function Literals and Closures</h2>
+
+<p>
+Catching the error condition in each handler introduces a lot of repeated code.
+What if we could wrap each of the handlers in a function that does this
+validation and error checking? Go's
+<a href="/ref/spec#Function_literals">function
+literals</a> provide a powerful means of abstracting functionality
+that can help us here.
+</p>
+
+<p>
+First, we re-write the function definition of each of the handlers to accept
+a title string:
+</p>
+
+<pre>
+func viewHandler(w http.ResponseWriter, r *http.Request, title string)
+func editHandler(w http.ResponseWriter, r *http.Request, title string)
+func saveHandler(w http.ResponseWriter, r *http.Request, title string)
+</pre>
+
+<p>
+Now let's define a wrapper function that <i>takes a function of the above
+type</i>, and returns a function of type <code>http.HandlerFunc</code>
+(suitable to be passed to the function <code>http.HandleFunc</code>):
+</p>
+
+<pre>
+func makeHandler(fn func (http.ResponseWriter, *http.Request, string)) http.HandlerFunc {
+	return func(w http.ResponseWriter, r *http.Request) {
+		// Here we will extract the page title from the Request,
+		// and call the provided handler 'fn'
+	}
+}
+</pre>
+
+<p>
+The returned function is called a closure because it encloses values defined
+outside of it. In this case, the variable <code>fn</code> (the single argument
+to <code>makeHandler</code>) is enclosed by the closure. The variable
+<code>fn</code> will be one of our save, edit, or view handlers.
+</p>
+
+<p>
+Now we can take the code from <code>getTitle</code> and use it here
+(with some minor modifications):
+</p>
+
+{{code "doc/articles/wiki/final.go" `/func makeHandler/` `/^}/`}}
+
+<p>
+The closure returned by <code>makeHandler</code> is a function that takes
+an <code>http.ResponseWriter</code> and <code>http.Request</code> (in other
+words, an <code>http.HandlerFunc</code>).
+The closure extracts the <code>title</code> from the request path, and
+validates it with the <code>TitleValidator</code> regexp. If the
+<code>title</code> is invalid, an error will be written to the
+<code>ResponseWriter</code> using the <code>http.NotFound</code> function.
+If the <code>title</code> is valid, the enclosed handler function
+<code>fn</code> will be called with the <code>ResponseWriter</code>,
+<code>Request</code>, and <code>title</code> as arguments.
+</p>
+
+<p>
+Now we can wrap the handler functions with <code>makeHandler</code> in
+<code>main</code>, before they are registered with the <code>http</code>
+package:
+</p>
+
+{{code "doc/articles/wiki/final.go" `/func main/` `/^}/`}}
+
+<p>
+Finally we remove the calls to <code>getTitle</code> from the handler functions,
+making them much simpler:
+</p>
+
+{{code "doc/articles/wiki/final.go" `/^func viewHandler/` `/^}/`}}
+{{code "doc/articles/wiki/final.go" `/^func editHandler/` `/^}/`}}
+{{code "doc/articles/wiki/final.go" `/^func saveHandler/` `/^}/`}}
+
+<h2>Try it out!</h2>
+
+<p>
+<a href="final.go">Click here to view the final code listing.</a>
+</p>
+
+<p>
+Recompile the code, and run the app:
+</p>
+
+<pre>
+$ go build wiki.go
+$ ./wiki
+</pre>
+
+<p>
+Visiting <a href="http://localhost:8080/view/ANewPage">http://localhost:8080/view/ANewPage</a>
+should present you with the page edit form. You should then be able to
+enter some text, click 'Save', and be redirected to the newly created page.
+</p>
+
+<h2>Other tasks</h2>
+
+<p>
+Here are some simple tasks you might want to tackle on your own:
+</p>
+
+<ul>
+<li>Store templates in <code>tmpl/</code> and page data in <code>data/</code>.
+<li>Add a handler to make the web root redirect to
+	<code>/view/FrontPage</code>.</li>
+<li>Spruce up the page templates by making them valid HTML and adding some
+	CSS rules.</li>
+<li>Implement inter-page linking by converting instances of
+	<code>[PageName]</code> to <br>
+	<code>&lt;a href="/view/PageName"&gt;PageName&lt;/a&gt;</code>.
+	(hint: you could use <code>regexp.ReplaceAllFunc</code> to do this)
+	</li>
+</ul>

+There is a suite of programs to build and process Go source code.
+Instead of being run directly, programs in the suite are usually invoked
+by the <a href="/cmd/go/">go</a> program.
+</p>
+
+<p>
+The most common way to run these programs is as a subcommand of the go program,
+for instance as <code>go fmt</code>. Run like this, the command operates on
+complete packages of Go source code, with the go program invoking the
+underlying binary with arguments appropriate to package-level processing.
+</p>
+
+<p>
+The programs can also be run as stand-alone binaries, with unmodified arguments,
+using the go <code>tool</code> subcommand, such as <code>go tool vet</code>.
+This style of invocation allows, for instance, checking a single source file
+rather than an entire package: <code>go tool vet myprogram.go</code> as
+compared to <code>go vet mypackage</code>.
+</p>
+
+<p>
+Finally the <code>fmt</code> and <code>godoc</code> commands are installed
+as regular binaries called <code>gofmt</code> and <code>godoc</code> because

+	<li>Each package consists of one or more Go source files in a single directory.</li>
+	<li>The path to a package's directory determines its <i>import path</i>.</li>
+</ul>
+
+<p>
+Note that this differs from other programming environments in which every
+project has a separate workspace and workspaces are closely tied to version
+control repositories.
+</p>
+
+<h3 id="Workspaces">Workspaces</h3>
+
+<p>
+A workspace is a directory hierarchy with three directories at its root:
+</p>
+
+<ul>
+<li><code>src</code> contains Go source files,
+<li><code>pkg</code> contains package objects, and
+<li><code>bin</code> contains executable commands.
+</ul>
+
+<p>
+The <code>go</code> tool builds source packages and installs the resulting
+binaries to the <code>pkg</code> and <code>bin</code> directories.
+</p>
+
+<p>
+The <code>src</code> subdirectory typically contains multiple version control
+repositories (such as for Git or Mercurial) that track the development of one
+or more source packages.
+</p>
+
+<p>
+To give you an idea of how a workspace looks in practice, here's an example:
+</p>
+
+<pre>
+bin/
+    hello                          # command executable
+    outyet                         # command executable
+pkg/
+    linux_amd64/
+        github.com/golang/example/
+            stringutil.a           # package object
+src/
+    <a href="https://github.com/golang/example/">github.com/golang/example/</a>
+        .git/                      # Git repository metadata
+	hello/
+	    hello.go               # command source
+	outyet/
+	    main.go                # command source
+	    main_test.go           # test source
+	stringutil/
+	    reverse.go             # package source

+        .git/                      # Git repository metadata
+	bmp/
+	    reader.go              # package source
+	    writer.go              # package source
+    ... (many more repositories and packages omitted) ...
+</pre>
+
+<p>
+The tree above shows a workspace containing two repositories
+(<code>example</code> and <code>image</code>).
+The <code>example</code> repository contains two commands (<code>hello</code>
+and <code>outyet</code>) and one library (<code>stringutil</code>).
+The <code>image</code> repository contains the <code>bmp</code> package
+and <a href="https://godoc.org/golang.org/x/image">several others</a>.
+</p>
+
+<p>
+A typical workspace contains many source repositories containing many
+packages and commands. Most Go programmers keep <i>all</i> their Go source code
+and dependencies in a single workspace.
+</p>
+
+<p>
+Commands and libraries are built from different kinds of source packages.
+We will discuss the distinction <a href="#PackageNames">later</a>.
+</p>
+
+
+<h3 id="GOPATH">The <code>GOPATH</code> environment variable</h3>
+
+<p>
+The <code>GOPATH</code> environment variable specifies the location of your
+workspace. It defaults to a directory named <code>go</code> inside your home directory,
+so <code>$HOME/go</code> on Unix,
+<code>$home/go</code> on Plan 9,
+and <code>%USERPROFILE%\go</code> (usually <code>C:\Users\YourName\go</code>) on Windows.
+If you would like to work in a different location, you will need to set
+<code>GOPATH</code> to the path to that directory.
+(Another common setup is to set <code>GOPATH=$HOME</code>.)
+Note that <code>GOPATH</code> must <b>not</b> be the
+same path as your Go installation.
+</p>
+
+<p>
+The command <code>go</code> <code>env</code> <code>GOPATH</code>
+prints the effective current <code>GOPATH</code>;
+it prints the default location if the environment variable is unset.
+</p>
+
+<p>
+For convenience, add the workspace's <code>bin</code> subdirectory
+to your <code>PATH</code>:
+</p>
+
+<pre>
+$ <b>export PATH=$PATH:$(go env GOPATH)/bin</b>
+</pre>
+
+<p>
+The scripts in the rest of this document use <code>$GOPATH</code>
+instead of <code>$(go env GOPATH)</code> for brevity.
+To make the scripts run as written
+if you have not set GOPATH,
+you can substitute $HOME/go in those commands
+or else run:
+</p>
+
+<pre>
+$ <b>export GOPATH=$(go env GOPATH)</b>
+</pre>
+
+<p>
+To learn more about the <code>GOPATH</code> environment variable, see
+<a href="/cmd/go/#hdr-GOPATH_environment_variable"><code>'go help gopath'</code></a>.

+</p>
+
+<h3 id="ImportPaths">Import paths</h3>
+
+<p>
+An <i>import path</i> is a string that uniquely identifies a package.
+A package's import path corresponds to its location inside a workspace
+or in a remote repository (explained below).
+</p>
+
+<p>
+The packages from the standard library are given short import paths such as
+<code>"fmt"</code> and <code>"net/http"</code>.
+For your own packages, you must choose a base path that is unlikely to
+collide with future additions to the standard library or other external
+libraries.
+</p>
+
+<p>
+If you keep your code in a source repository somewhere, then you should use the
+root of that source repository as your base path.
+For instance, if you have a <a href="https://github.com/">GitHub</a> account at
+<code>github.com/user</code>, that should be your base path.
+</p>
+
+<p>
+Note that you don't need to publish your code to a remote repository before you
+can build it. It's just a good habit to organize your code as if you will
+publish it someday. In practice you can choose any arbitrary path name,
+as long as it is unique to the standard library and greater Go ecosystem.
+</p>
+
+<p>
+We'll use <code>github.com/user</code> as our base path. Create a directory
+inside your workspace in which to keep source code:
+</p>
+
+<pre>
+$ <b>mkdir -p $GOPATH/src/github.com/user</b>
+</pre>
+
+
+<h3 id="Command">Your first program</h3>
+
+<p>
+To compile and run a simple program, first choose a package path (we'll use
+<code>github.com/user/hello</code>) and create a corresponding package directory
+inside your workspace:
+</p>
+
+<pre>
+$ <b>mkdir $GOPATH/src/github.com/user/hello</b>
+</pre>
+
+<p>
+Next, create a file named <code>hello.go</code> inside that directory,
+containing the following Go code.
+</p>
+
+<pre>
+package main
+
+import "fmt"
+
+func main() {
+	fmt.Printf("Hello, world.\n")
+}
+</pre>
+
+<p>
+Now you can build and install that program with the <code>go</code> tool:
+</p>
+
+<pre>
+$ <b>go install github.com/user/hello</b>
+</pre>
+
+<p>
+Note that you can run this command from anywhere on your system. The
+<code>go</code> tool finds the source code by looking for the
+<code>github.com/user/hello</code> package inside the workspace specified by
+<code>GOPATH</code>.
+</p>
+
+<p>
+You can also omit the package path if you run <code>go install</code> from the
+package directory:
+</p>
+
+<pre>
+$ <b>cd $GOPATH/src/github.com/user/hello</b>
+$ <b>go install</b>
+</pre>
+
+<p>
+This command builds the <code>hello</code> command, producing an executable
+binary. It then installs that binary to the workspace's <code>bin</code>
+directory as <code>hello</code> (or, under Windows, <code>hello.exe</code>).
+In our example, that will be <code>$GOPATH/bin/hello</code>, which is
+<code>$HOME/work/bin/hello</code>.
+</p>
+
+<p>
+The <code>go</code> tool will only print output when an error occurs, so if
+these commands produce no output they have executed successfully.
+</p>
+
+<p>
+You can now run the program by typing its full path at the command line:
+</p>
+
+<pre>
+$ <b>$GOPATH/bin/hello</b>
+Hello, world.
+</pre>
+
+<p>
+Or, as you have added <code>$GOPATH/bin</code> to your <code>PATH</code>,
+just type the binary name:
+</p>
+
+<pre>
+$ <b>hello</b>
+Hello, world.
+</pre>
+
+<p>
+If you're using a source control system, now would be a good time to initialize
+a repository, add the files, and commit your first change. Again, this step is
+optional: you do not need to use source control to write Go code.
+</p>
+
+<pre>
+$ <b>cd $GOPATH/src/github.com/user/hello</b>
+$ <b>git init</b>
+Initialized empty Git repository in /home/user/work/src/github.com/user/hello/.git/
+$ <b>git add hello.go</b>
+$ <b>git commit -m "initial commit"</b>
+[master (root-commit) 0b4507d] initial commit
+ 1 file changed, 1 insertion(+)
+  create mode 100644 hello.go
+</pre>
+
+<p>
+Pushing the code to a remote repository is left as an exercise for the reader.
+</p>
+
+
+<h3 id="Library">Your first library</h3>
+
+<p>
+Let's write a library and use it from the <code>hello</code> program.
+</p>
+
+<p>
+Again, the first step is to choose a package path (we'll use
+<code>github.com/user/stringutil</code>) and create the package directory:
+</p>
+
+<pre>
+$ <b>mkdir $GOPATH/src/github.com/user/stringutil</b>
+</pre>
+
+<p>
+Next, create a file named <code>reverse.go</code> in that directory with the
+following contents.
+</p>
+
+<pre>
+// Package stringutil contains utility functions for working with strings.
+package stringutil
+
+// Reverse returns its argument string reversed rune-wise left to right.
+func Reverse(s string) string {
+	r := []rune(s)
+	for i, j := 0, len(r)-1; i &lt; len(r)/2; i, j = i+1, j-1 {
+		r[i], r[j] = r[j], r[i]
+	}
+	return string(r)
+}
+</pre>
+
+<p>
+Now, test that the package compiles with <code>go build</code>:
+</p>
+
+<pre>
+$ <b>go build github.com/user/stringutil</b>
+</pre>
+
+<p>
+Or, if you are working in the package's source directory, just:
+</p>
+
+<pre>
+$ <b>go build</b>
+</pre>
+
+<p>
+This won't produce an output file. To do that, you must use <code>go
+install</code>, which places the package object inside the <code>pkg</code>
+directory of the workspace.
+</p>
+
+<p>
+After confirming that the <code>stringutil</code> package builds,
+modify your original <code>hello.go</code> (which is in
+<code>$GOPATH/src/github.com/user/hello</code>) to use it:
+</p>
+
+<pre>
+package main
+
+import (
+	"fmt"
+
+	<b>"github.com/user/stringutil"</b>
+)
+
+func main() {
+	fmt.Printf(stringutil.Reverse("!oG ,olleH"))
+}
+</pre>
+
+<p>
+Whenever the <code>go</code> tool installs a package or binary, it also
+installs whatever dependencies it has.
+So when you install the <code>hello</code> program
+</p>
+
+<pre>
+$ <b>go install github.com/user/hello</b>
+</pre>
+
+<p>
+the <code>stringutil</code> package will be installed as well, automatically.
+</p>
+
+<p>
+Running the new version of the program, you should see a new, reversed message:
+</p>
+
+<pre>
+$ <b>hello</b>
+Hello, Go!
+</pre>
+
+<p>
+After the steps above, your workspace should look like this:
+</p>
+
+<pre>
+bin/
+    hello                 # command executable
+pkg/
+    linux_amd64/          # this will reflect your OS and architecture
+        github.com/user/
+            stringutil.a  # package object
+src/
+    github.com/user/
+        hello/
+            hello.go      # command source
+        stringutil/
+            reverse.go    # package source
+</pre>
+
+<p>
+Note that <code>go install</code> placed the <code>stringutil.a</code> object
+in a directory inside <code>pkg/linux_amd64</code> that mirrors its source
+directory.
+This is so that future invocations of the <code>go</code> tool can find the
+package object and avoid recompiling the package unnecessarily.
+The <code>linux_amd64</code> part is there to aid in cross-compilation,
+and will reflect the operating system and architecture of your system.
+</p>
+
+<p>
+Go command executables are statically linked; the package objects need not
+be present to run Go programs.
+</p>
+
+
+<h3 id="PackageNames">Package names</h3>
+
+<p>
+The first statement in a Go source file must be
+</p>
+
+<pre>
+package <i>name</i>
+</pre>
+
+<p>
+where <code><i>name</i></code> is the package's default name for imports.
+(All files in a package must use the same <code><i>name</i></code>.)
+</p>
+
+<p>
+Go's convention is that the package name is the last element of the
+import path: the package imported as "<code>crypto/rot13</code>"
+should be named <code>rot13</code>.
+</p>
+
+<p>
+Executable commands must always use <code>package main</code>.
+</p>
+
+<p>
+There is no requirement that package names be unique
+across all packages linked into a single binary,
+only that the import paths (their full file names) be unique.
+</p>
+
+<p>
+See <a href="/doc/effective_go.html#names">Effective Go</a> to learn more about
+Go's naming conventions.
+</p>
+
+
+<h2 id="Testing">Testing</h2>
+
+<p>
+Go has a lightweight test framework composed of the <code>go test</code>
+command and the <code>testing</code> package.
+</p>
+
+<p>
+You write a test by creating a file with a name ending in <code>_test.go</code>
+that contains functions named <code>TestXXX</code> with signature
+<code>func (t *testing.T)</code>.
+The test framework runs each such function;
+if the function calls a failure function such as <code>t.Error</code> or
+<code>t.Fail</code>, the test is considered to have failed.
+</p>
+
+<p>
+Add a test to the <code>stringutil</code> package by creating the file
+<code>$GOPATH/src/github.com/user/stringutil/reverse_test.go</code> containing
+the following Go code.
+</p>
+
+<pre>
+package stringutil
+
+import "testing"
+
+func TestReverse(t *testing.T) {
+	cases := []struct {
+		in, want string
+	}{
+		{"Hello, world", "dlrow ,olleH"},
+		{"Hello, 世界", "界世 ,olleH"},
+		{"", ""},
+	}
+	for _, c := range cases {
+		got := Reverse(c.in)
+		if got != c.want {
+			t.Errorf("Reverse(%q) == %q, want %q", c.in, got, c.want)
+		}
+	}
+}
+</pre>
+
+<p>
+Then run the test with <code>go test</code>:
+</p>
+
+<pre>
+$ <b>go test github.com/user/stringutil</b>
+ok  	github.com/user/stringutil 0.165s
+</pre>
+
+<p>
+As always, if you are running the <code>go</code> tool from the package
+directory, you can omit the package path:
+</p>
+
+<pre>
+$ <b>go test</b>
+ok  	github.com/user/stringutil 0.165s
+</pre>
+
+<p>
+Run <code><a href="/cmd/go/#hdr-Test_packages">go help test</a></code> and see the
+<a href="/pkg/testing/">testing package documentation</a> for more detail.
+</p>
+
+
+<h2 id="remote">Remote packages</h2>
+
+<p>
+An import path can describe how to obtain the package source code using a
+revision control system such as Git or Mercurial. The <code>go</code> tool uses
+this property to automatically fetch packages from remote repositories.
+For instance, the examples described in this document are also kept in a
+Git repository hosted at GitHub
+<code><a href="https://github.com/golang/example">github.com/golang/example</a></code>.
+If you include the repository URL in the package's import path,
+<code>go get</code> will fetch, build, and install it automatically:
+</p>
+
+<pre>
+$ <b>go get github.com/golang/example/hello</b>
+$ <b>$GOPATH/bin/hello</b>
+Hello, Go examples!
+</pre>
+
+<p>
+If the specified package is not present in a workspace, <code>go get</code>
+will place it inside the first workspace specified by <code>GOPATH</code>.
+(If the package does already exist, <code>go get</code> skips the remote
+fetch and behaves the same as <code>go install</code>.)
+</p>
+
+<p>
+After issuing the above <code>go get</code> command, the workspace directory
+tree should now look like this:
+</p>
+
+<pre>
+bin/
+    hello                           # command executable
+pkg/
+    linux_amd64/
+        github.com/golang/example/
+            stringutil.a            # package object
+        github.com/user/
+            stringutil.a            # package object
+src/
+    github.com/golang/example/
+	.git/                       # Git repository metadata
+        hello/
+            hello.go                # command source
+        stringutil/
+            reverse.go              # package source
+            reverse_test.go         # test source
+    github.com/user/
+        hello/
+            hello.go                # command source
+        stringutil/
+            reverse.go              # package source
+            reverse_test.go         # test source
+</pre>
+
+<p>
+The <code>hello</code> command hosted at GitHub depends on the
+<code>stringutil</code> package within the same repository. The imports in
+<code>hello.go</code> file use the same import path convention, so the
+<code>go get</code> command is able to locate and install the dependent
+package, too.
+</p>
+
+<pre>
+import "github.com/golang/example/stringutil"
+</pre>
+
+<p>
+This convention is the easiest way to make your Go packages available for
+others to use.
+The <a href="//golang.org/wiki/Projects">Go Wiki</a>
+and <a href="//godoc.org/">godoc.org</a>

+<codewalk title="How to Write a Codewalk">
+
+<step title="Introduction" src="doc/codewalk/codewalk.xml">
+	A codewalk is a guided tour through a piece of code.
+	It consists of a sequence of steps, each typically explaining
+	a highlighted section of code.
+	<br/><br/>
+	
+	The <a href="/cmd/godoc">godoc</a> web server translates
+	an XML file like the one in the main window pane into the HTML
+	page that you're viewing now.
+	<br/><br/>
+	
+	The codewalk with URL path <code>/doc/codewalk/</code><i>name</i>
+	is loaded from the input file <code>$GOROOT/doc/codewalk/</code><i>name</i><code>.xml</code>.
+	<br/><br/>
+	
+	This codewalk explains how to write a codewalk by examining
+	its own source code,
+	<code><a href="/doc/codewalk/codewalk.xml">$GOROOT/doc/codewalk/codewalk.xml</a></code>,
+	shown in the main window pane to the left.	
+</step>
+
+<step title="Title" src="doc/codewalk/codewalk.xml:/title=/">
+	The codewalk input file is an XML file containing a single
+	<code>&lt;codewalk&gt;</code> element.
+	That element's <code>title</code> attribute gives the title
+	that is used both on the codewalk page and in the codewalk list.
+</step>
+
+<step title="Steps" src="doc/codewalk/codewalk.xml:/&lt;step/,/step&gt;/">
+	Each step in the codewalk is a <code>&lt;step&gt;</code> element 
+	nested inside the main <code>&lt;codewalk&gt;</code>.
+	The step element's <code>title</code> attribute gives the step's title,
+	which is shown in a shaded bar above the main step text.
+	The element's <code>src</code> attribute specifies the source
+	code to show in the main window pane and, optionally, a range of 
+	lines to highlight.
+	<br/><br/>
+	
+	The first step in this codewalk does not highlight any lines:
+	its <code>src</code> is just a file name.
+</step>
+
+<step title="Specifying a source line" src='doc/codewalk/codewalk.xml:/title="Title"/'>
+	The most complex part of the codewalk specification is
+	saying what lines to highlight.
+	Instead of ordinary line numbers,
+	the codewalk uses an address syntax that makes it possible
+	to describe the match by its content.
+	As the file gets edited, this descriptive address has a better
+	chance to continue to refer to the right section of the file.
+	<br/><br/>
+
+	To specify a source line, use a <code>src</code> attribute of the form
+	<i>filename</i><code>:</code><i>address</i>,
+	where <i>address</i> is an address in the syntax used by the text editors <i>sam</i> and <i>acme</i>.
+	<br/><br/>
+	
+	The simplest address is a single regular expression.
+	The highlighted line in the main window pane shows that the
+	address for the &ldquo;Title&rdquo; step was <code>/title=/</code>,
+	which matches the first instance of that <a href="/pkg/regexp">regular expression</a> (<code>title=</code>) in the file.
+</step>
+
+<step title="Specifying a source range" src='doc/codewalk/codewalk.xml:/title="Steps"/'>
+	To highlight a range of source lines, the simplest address to use is
+	a pair of regular expressions
+	<code>/</code><i>regexp1</i><code>/,/</code><i>regexp2</i><code>/</code>.
+	The highlight begins with the line containing the first match for <i>regexp1</i>
+	and ends with the line containing the first match for <i>regexp2</i>
+	after the end of the match for <i>regexp1</i>.
+	Ignoring the HTML quoting, 
+	The line containing the first match for <i>regexp1</i> will be the first one highlighted,
+	and the line containing the first match for <i>regexp2</i>.
+	<br/><br/>
+	
+	The address <code>/&lt;step/,/step&gt;/</code> looks for the first instance of
+	<code>&lt;step</code> in the file, and then starting after that point,
+	looks for the first instance of <code>step&gt;</code>.
+	(Click on the &ldquo;Steps&rdquo; step above to see the highlight in action.)
+	Note that the <code>&lt;</code> and <code>&gt;</code> had to be written
+	using XML escapes in order to be valid XML.
+</step>
+
+<step title="Advanced addressing" src="doc/codewalk/codewalk.xml:/Advanced/,/step&gt;/">
+	The <code>/</code><i>regexp</i><code>/</code>
+ 	and <code>/</code><i>regexp1</i><code>/,/</code><i>regexp2</i><code>/</code>
+ 	forms suffice for most highlighting.
+ 	<br/><br/>
+
+	The full address syntax is summarized in this table
+	(an excerpt of Table II from
+	<a href="https://9p.io/sys/doc/sam/sam.html">The text editor <code>sam</code></a>):
+	<br/><br/>

+Generating random text: a Markov chain algorithm
+
+Based on the program presented in the "Design and Implementation" chapter
+of The Practice of Programming (Kernighan and Pike, Addison-Wesley 1999).
+See also Computer Recreations, Scientific American 260, 122 - 125 (1989).
+
+A Markov chain algorithm generates text by creating a statistical model of
+potential textual suffixes for a given prefix. Consider this text:
+
+	I am not a number! I am a free man!
+
+Our Markov chain algorithm would arrange this text into this set of prefixes
+and suffixes, or "chain": (This table assumes a prefix length of two words.)
+
+	Prefix       Suffix
+
+	"" ""        I
+	"" I         am
+	I am         a
+	I am         not
+	a free       man!
+	am a         free
+	am not       a
+	a number!    I
+	number! I    am
+	not a        number!
+
+To generate text using this table we select an initial prefix ("I am", for
+example), choose one of the suffixes associated with that prefix at random
+with probability determined by the input statistics ("a"),
+and then create a new prefix by removing the first word from the prefix
+and appending the suffix (making the new prefix is "am a"). Repeat this process
+until we can't find any suffixes for the current prefix or we exceed the word
+limit. (The word limit is necessary as the chain table may contain cycles.)
+
+Our version of this program reads text from standard input, parsing it into a
+Markov chain, and writes generated text to standard output.
+The prefix and output lengths can be specified using the -prefix and -words
+flags on the command-line.

+	"not a":      {"number!"},
+}</pre>
+	While each prefix consists of multiple words, we
+	store prefixes in the map as a single <code>string</code>.
+	It would seem more natural to store the prefix as a
+	<code>[]string</code>, but we can't do this with a map because the
+	key type of a map must implement equality (and slices do not).
+	<br/><br/>
+	Therefore, in most of our code we will model prefixes as a
+	<code>[]string</code> and join the strings together with a space
+	to generate the map key:
+	<pre>
+Prefix               Map key
+
+[]string{"", ""}     " "
+[]string{"", "I"}    " I"
+[]string{"I", "am"}  "I am"
+</pre>
+</step>
+
+<step title="The Chain struct" src="doc/codewalk/markov.go:/type Chain/,/}/">
+	The complete state of the chain table consists of the table itself and
+	the word length of the prefixes. The <code>Chain</code> struct stores
+	this data.
+</step>
+
+<step title="The NewChain constructor function" src="doc/codewalk/markov.go:/func New/,/\n}/">
+	The <code>Chain</code> struct has two unexported fields (those that
+	do not begin with an upper case character), and so we write a
+	<code>NewChain</code> constructor function that initializes the
+	<code>chain</code> map with <code>make</code> and sets the
+	<code>prefixLen</code> field.
+	<br/><br/>
+	This is constructor function is not strictly necessary as this entire
+	program is within a single package (<code>main</code>) and therefore
+	there is little practical difference between exported and unexported
+	fields. We could just as easily write out the contents of this function
+	when we want to construct a new Chain.
+	But using these unexported fields is good practice; it clearly denotes
+	that only methods of Chain and its constructor function should access
+	those fields. Also, structuring <code>Chain</code> like this means we
+	could easily move it into its own package at some later date.
+</step>
+
+<step title="The Prefix type" src="doc/codewalk/markov.go:/type Prefix/">
+	Since we'll be working with prefixes often, we define a
+	<code>Prefix</code> type with the concrete type <code>[]string</code>.
+	Defining a named type clearly allows us to be explicit when we are
+	working with a prefix instead of just a <code>[]string</code>.
+	Also, in Go we can define methods on any named type (not just structs),
+	so we can add methods that operate on <code>Prefix</code> if we need to.
+</step>
+
+<step title="The String method" src="doc/codewalk/markov.go:/func[^\n]+String/,/}/">
+	The first method we define on <code>Prefix</code> is
+	<code>String</code>. It returns a <code>string</code> representation
+	of a <code>Prefix</code> by joining the slice elements together with
+	spaces. We will use this method to generate keys when working with
+	the chain map.
+</step>
+
+<step title="Building the chain" src="doc/codewalk/markov.go:/func[^\n]+Build/,/\n}/">
+	The <code>Build</code> method reads text from an <code>io.Reader</code>
+	and parses it into prefixes and suffixes that are stored in the
+	<code>Chain</code>.
+	<br/><br/>
+	The <code><a href="/pkg/io/#Reader">io.Reader</a></code> is an
+	interface type that is widely used by the standard library and
+	other Go code. Our code uses the
+	<code><a href="/pkg/fmt/#Fscan">fmt.Fscan</a></code> function, which
+	reads space-separated values from an <code>io.Reader</code>.
+	<br/><br/>
+	The <code>Build</code> method returns once the <code>Reader</code>'s
+	<code>Read</code> method returns <code>io.EOF</code> (end of file)
+	or some other read error occurs.
+</step>
+
+<step title="Buffering the input" src="doc/codewalk/markov.go:/bufio\.NewReader/">
+	This function does many small reads, which can be inefficient for some
+	<code>Readers</code>. For efficiency we wrap the provided
+	<code>io.Reader</code> with
+	<code><a href="/pkg/bufio/">bufio.NewReader</a></code> to create a
+	new <code>io.Reader</code> that provides buffering.
+</step>
+
+<step title="The Prefix variable" src="doc/codewalk/markov.go:/make\(Prefix/">
+	At the top of the function we make a <code>Prefix</code> slice
+	<code>p</code> using the <code>Chain</code>'s <code>prefixLen</code>
+	field as its length.
+	We'll use this variable to hold the current prefix and mutate it with
+	each new word we encounter.
+</step>
+
+<step title="Scanning words" src="doc/codewalk/markov.go:/var s string/,/\n		}/">
+	In our loop we read words from the <code>Reader</code> into a
+	<code>string</code> variable <code>s</code> using
+	<code>fmt.Fscan</code>. Since <code>Fscan</code> uses space to
+	separate each input value, each call will yield just one word
+	(including punctuation), which is exactly what we need.
+	<br/><br/>
+	<code>Fscan</code> returns an error if it encounters a read error
+	(<code>io.EOF</code>, for example) or if it can't scan the requested
+	value (in our case, a single string). In either case we just want to
+	stop scanning, so we <code>break</code> out of the loop.
+</step>
+
+<step title="Adding a prefix and suffix to the chain" src="doc/codewalk/markov.go:/	key/,/key\], s\)">
+	The word stored in <code>s</code> is a new suffix. We add the new
+	prefix/suffix combination to the <code>chain</code> map by computing
+	the map key with <code>p.String</code> and appending the suffix
+	to the slice stored under that key.
+	<br/><br/>
+	The built-in <code>append</code> function appends elements to a slice
+	and allocates new storage when necessary. When the provided slice is
+	<code>nil</code>, <code>append</code> allocates a new slice.
+	This behavior conveniently ties in with the semantics of our map:
+	retrieving an unset key returns the zero value of the value type and
+	the zero value of <code>[]string</code> is <code>nil</code>.
+	When our program encounters a new prefix (yielding a <code>nil</code>
+	value in the map) <code>append</code> will allocate a new slice.
+	<br/><br/>
+	For more information about the <code>append</code> function and slices
+	in general see the
+	<a href="/doc/articles/slices_usage_and_internals.html">Slices: usage and internals</a> article.
+</step>
+
+<step title="Pushing the suffix onto the prefix" src="doc/codewalk/markov.go:/p\.Shift/">
+	Before reading the next word our algorithm requires us to drop the
+	first word from the prefix and push the current suffix onto the prefix.
+	<br/><br/>
+	When in this state
+	<pre>
+p == Prefix{"I", "am"}
+s == "not" </pre>
+	the new value for <code>p</code> would be
+	<pre>
+p == Prefix{"am", "not"}</pre>
+	This operation is also required during text generation so we put
+	the code to perform this mutation of the slice inside a method on
+	<code>Prefix</code> named <code>Shift</code>.
+</step>
+
+<step title="The Shift method" src="doc/codewalk/markov.go:/func[^\n]+Shift/,/\n}/">
+	The <code>Shift</code> method uses the built-in <code>copy</code>
+	function to copy the last len(p)-1 elements of <code>p</code> to
+	the start of the slice, effectively moving the elements
+	one index to the left (if you consider zero as the leftmost index).
+	<pre>
+p := Prefix{"I", "am"}
+copy(p, p[1:])
+// p == Prefix{"am", "am"}</pre>
+	We then assign the provided <code>word</code> to the last index
+	of the slice:
+	<pre>
+// suffix == "not"
+p[len(p)-1] = suffix
+// p == Prefix{"am", "not"}</pre>
+</step>
+
+<step title="Generating text" src="doc/codewalk/markov.go:/func[^\n]+Generate/,/\n}/">
+	The <code>Generate</code> method is similar to <code>Build</code>
+	except that instead of reading words from a <code>Reader</code>
+	and storing them in a map, it reads words from the map and
+	appends them to a slice (<code>words</code>).
+	<br/><br/>
+	<code>Generate</code> uses a conditional for loop to generate
+	up to <code>n</code> words.
+</step>
+
+<step title="Getting potential suffixes" src="doc/codewalk/markov.go:/choices/,/}\n/">
+	At each iteration of the loop we retrieve a list of potential suffixes
+	for the current prefix. We access the <code>chain</code> map at key
+	<code>p.String()</code> and assign its contents to <code>choices</code>.
+	<br/><br/>
+	If <code>len(choices)</code> is zero we break out of the loop as there
+	are no potential suffixes for that prefix.
+	This test also works if the key isn't present in the map at all:
+	in that case, <code>choices</code> will be <code>nil</code> and the
+	length of a <code>nil</code> slice is zero.
+</step>
+
+<step title="Choosing a suffix at random" src="doc/codewalk/markov.go:/next := choices/,/Shift/">
+	To choose a suffix we use the
+	<code><a href="/pkg/math/rand/#Intn">rand.Intn</a></code> function.
+	It returns a random integer up to (but not including) the provided
+	value. Passing in <code>len(choices)</code> gives us a random index
+	into the full length of the list.
+	<br/><br/>
+	We use that index to pick our new suffix, assign it to
+	<code>next</code> and append it to the <code>words</code> slice.
+	<br/><br/>
+	Next, we <code>Shift</code> the new suffix onto the prefix just as
+	we did in the <code>Build</code> method.
+</step>
+
+<step title="Returning the generated text" src="doc/codewalk/markov.go:/Join\(words/">
+	Before returning the generated text as a string, we use the
+	<code>strings.Join</code> function to join the elements of
+	the <code>words</code> slice together, separated by spaces.
+</step>
+
+<step title="Command-line flags" src="doc/codewalk/markov.go:/Register command-line flags/,/prefixLen/">
+	To make it easy to tweak the prefix and generated text lengths we
+	use the <code><a href="/pkg/flag/">flag</a></code> package to parse
+	command-line flags.
+	<br/><br/>
+	These calls to <code>flag.Int</code> register new flags with the
+	<code>flag</code> package. The arguments to <code>Int</code> are the
+	flag name, its default value, and a description. The <code>Int</code>
+	function returns a pointer to an integer that will contain the
+	user-supplied value (or the default value if the flag was omitted on
+	the command-line).
+</step>
+
+<step title="Program set up" src="doc/codewalk/markov.go:/flag.Parse/,/rand.Seed/">
+	The <code>main</code> function begins by parsing the command-line
+	flags with <code>flag.Parse</code> and seeding the <code>rand</code>
+	package's random number generator with the current time.
+	<br/><br/>
+	If the command-line flags provided by the user are invalid the
+	<code>flag.Parse</code> function will print an informative usage
+	message and terminate the program.
+</step>
+
+<step title="Creating and building a new Chain" src="doc/codewalk/markov.go:/c := NewChain/,/c\.Build/">
+	To create the new <code>Chain</code> we call <code>NewChain</code>
+	with the value of the <code>prefix</code> flag.
+	<br/><br/>
+	To build the chain we call <code>Build</code> with
+	<code>os.Stdin</code> (which implements <code>io.Reader</code>) so
+	that it will read its input from standard input.
+</step>
+
+<step title="Generating and printing text" src="doc/codewalk/markov.go:/c\.Generate/,/fmt.Println/">
+	Finally, to generate text we call <code>Generate</code> with
+	the value of the <code>words</code> flag and assigning the result
+	to the variable <code>text</code>.
+	<br/><br/>
+	Then we call <code>fmt.Println</code> to write the text to standard
+	output, followed by a carriage return.
+</step>
+
+<step title="Using this program" src="doc/codewalk/markov.go">
+	To use this program, first build it with the
+	<a href="/cmd/go/">go</a> command:
+	<pre>
+$ go build markov.go</pre>
+	And then execute it while piping in some input text:
+	<pre>
+$ echo "a man a plan a canal panama" \
+	| ./markov -prefix=1
+a plan a man a plan a canal panama</pre>
+	Here's a transcript of generating some text using the Go distribution's
+	README file as source material:
+	<pre>
+$ ./markov -words=10 &lt; $GOROOT/README
+This is the source code repository for the Go source
+$ ./markov -prefix=1 -words=10 &lt; $GOROOT/README
+This is the go directory (the one containing this README).
+$ ./markov -prefix=1 -words=10 &lt; $GOROOT/README
+This is the variable if you have just untarred a</pre>
+</step>
+
+<step title="An exercise for the reader" src="doc/codewalk/markov.go">
+	The <code>Generate</code> function does a lot of allocations when it
+	builds the <code>words</code> slice. As an exercise, modify it to
+	take an <code>io.Writer</code> to which it incrementally writes the
+	generated text with <code>Fprint</code>.
+	Aside from being more efficient this makes <code>Generate</code>
+	more symmetrical to <code>Build</code>.

+<codewalk title="Share Memory By Communicating">
+
+<step title="Introduction" src="doc/codewalk/urlpoll.go">
+Go's approach to concurrency differs from the traditional use of
+threads and shared memory. Philosophically, it can be summarized:
+<br/><br/>
+<i>Don't communicate by sharing memory; share memory by communicating.</i>
+<br/><br/>
+Channels allow you to pass references to data structures between goroutines.
+If you consider this as passing around ownership of the data (the ability to
+read and write it), they become a powerful and expressive synchronization 
+mechanism.
+<br/><br/>
+In this codewalk we will look at a simple program that polls a list of
+URLs, checking their HTTP response codes and periodically printing their state.
+</step>
+
+<step title="State type" src="doc/codewalk/urlpoll.go:/State/,/}/">
+The State type represents the state of a URL.
+<br/><br/>
+The Pollers send State values to the StateMonitor,
+which maintains a map of the current state of each URL.
+</step>
+
+<step title="Resource type" src="doc/codewalk/urlpoll.go:/Resource/,/}/">
+A Resource represents the state of a URL to be polled: the URL itself
+and the number of errors encountered since the last successful poll.
+<br/><br/>
+When the program starts, it allocates one Resource for each URL.
+The main goroutine and the Poller goroutines send the Resources to
+each other on channels.
+</step>
+
+<step title="Poller function" src="doc/codewalk/urlpoll.go:/func Poller/,/\n}/">
+Each Poller receives Resource pointers from an input channel.
+In this program, the convention is that sending a Resource pointer on
+a channel passes ownership of the underlying data from the sender
+to the receiver.  Because of this convention, we know that
+no two goroutines will access this Resource at the same time.
+This means we don't have to worry about locking to prevent concurrent 
+access to these data structures.
+<br/><br/>
+The Poller processes the Resource by calling its Poll method.
+<br/><br/>
+It sends a State value to the status channel, to inform the StateMonitor
+of the result of the Poll.
+<br/><br/>
+Finally, it sends the Resource pointer to the out channel. This can be
+interpreted as the Poller saying &quot;I'm done with this Resource&quot; and 
+returning ownership of it to the main goroutine. 
+<br/><br/>
+Several goroutines run Pollers, processing Resources in parallel.
+</step>
+
+<step title="The Poll method" src="doc/codewalk/urlpoll.go:/Poll executes/,/\n}/">
+The Poll method (of the Resource type) performs an HTTP HEAD request
+for the Resource's URL and returns the HTTP response's status code.
+If an error occurs, Poll logs the message to standard error and returns the 
+error string instead.
+</step>
+
+<step title="main function" src="doc/codewalk/urlpoll.go:/func main/,/\n}/">
+The main function starts the Poller and StateMonitor goroutines
+and then loops passing completed Resources back to the pending
+channel after appropriate delays.
+</step>
+
+<step title="Creating channels" src="doc/codewalk/urlpoll.go:/Create our/,/complete/">
+First, main makes two channels of *Resource, pending and complete.
+<br/><br/>
+Inside main, a new goroutine sends one Resource per URL to pending
+and the main goroutine receives completed Resources from complete.
+<br/><br/>
+The pending and complete channels are passed to each of the Poller
+goroutines, within which they are known as in and out. 
+</step>
+
+<step title="Initializing StateMonitor" src="doc/codewalk/urlpoll.go:/Launch the StateMonitor/,/statusInterval/">
+StateMonitor will initialize and launch a goroutine that stores the state 
+of each Resource. We will look at this function in detail later. 
+<br/><br/>
+For now, the important thing to note is that it returns a channel of State, 
+which is saved as status and passed to the Poller goroutines.
+</step>
+
+<step title="Launching Poller goroutines" src="doc/codewalk/urlpoll.go:/Launch some Poller/,/}/">
+Now that it has the necessary channels, main launches a number of
+Poller goroutines, passing the channels as arguments.
+The channels provide the means of communication between the main, Poller, and 
+StateMonitor goroutines.
+</step>
+
+<step title="Send Resources to pending" src="doc/codewalk/urlpoll.go:/Send some Resources/,/}\(\)/">
+To add the initial work to the system, main starts a new goroutine
+that allocates and sends one Resource per URL to pending.
+<br/><br/>
+The new goroutine is necessary because unbuffered channel sends and
+receives are synchronous. That means these channel sends will block until
+the Pollers are ready to read from pending.
+<br/><br/>
+Were these sends performed in the main goroutine with fewer Pollers than 
+channel sends, the program would reach a deadlock situation, because
+main would not yet be receiving from complete.
+<br/><br/>
+Exercise for the reader: modify this part of the program to read a list of
+URLs from a file. (You may want to move this goroutine into its own
+named function.)
+</step>
+
+<step title="Main Event Loop" src="doc/codewalk/urlpoll.go:/range complete/,/\n	}/">
+When a Poller is done with a Resource, it sends it on the complete channel.
+This loop receives those Resource pointers from complete.
+For each received Resource, it starts a new goroutine calling
+the Resource's Sleep method.  Using a new goroutine for each
+ensures that the sleeps can happen in parallel.
+<br/><br/>
+Note that any single Resource pointer may only be sent on either pending or
+complete at any one time. This ensures that a Resource is either being
+handled by a Poller goroutine or sleeping, but never both simultaneously.  
+In this way, we share our Resource data by communicating.
+</step>
+
+<step title="The Sleep method" src="doc/codewalk/urlpoll.go:/Sleep/,/\n}/">
+Sleep calls time.Sleep to pause before sending the Resource to done.
+The pause will either be of a fixed length (pollInterval) plus an
+additional delay proportional to the number of sequential errors (r.errCount).
+<br/><br/>
+This is an example of a typical Go idiom: a function intended to run inside 
+a goroutine takes a channel, upon which it sends its return value 
+(or other indication of completed state).
+</step>
+
+<step title="StateMonitor" src="doc/codewalk/urlpoll.go:/StateMonitor/,/\n}/">
+The StateMonitor receives State values on a channel and periodically
+outputs the state of all Resources being polled by the program.
+</step>
+
+<step title="The updates channel" src="doc/codewalk/urlpoll.go:/updates :=/">
+The variable updates is a channel of State, on which the Poller goroutines
+send State values.
+<br/><br/>
+This channel is returned by the function.
+</step>
+
+<step title="The urlStatus map" src="doc/codewalk/urlpoll.go:/urlStatus/">
+The variable urlStatus is a map of URLs to their most recent status. 
+</step>
+
+<step title="The Ticker object" src="doc/codewalk/urlpoll.go:/ticker/">
+A time.Ticker is an object that repeatedly sends a value on a channel at a 
+specified interval. 
+<br/><br/>
+In this case, ticker triggers the printing of the current state to 
+standard output every updateInterval nanoseconds.
+</step>
+
+<step title="The StateMonitor goroutine" src="doc/codewalk/urlpoll.go:/go func/,/}\(\)/">
+StateMonitor will loop forever, selecting on two channels: 
+ticker.C and update. The select statement blocks until one of its 
+communications is ready to proceed.
+<br/><br/>
+When StateMonitor receives a tick from ticker.C, it calls logState to
+print the current state.  When it receives a State update from updates,
+it records the new status in the urlStatus map.
+<br/><br/>
+Notice that this goroutine owns the urlStatus data structure,
+ensuring that it can only be accessed sequentially. 
+This prevents memory corruption issues that might arise from parallel reads 
+and/or writes to a shared map.
+</step>
+
+<step title="Conclusion" src="doc/codewalk/urlpoll.go">
+In this codewalk we have explored a simple example of using Go's concurrency
+primitives to share memory through communication.
+<br/><br/>
+This should provide a starting point from which to explore the ways in which
+goroutines and channels can be used to write expressive and concise concurrent
+programs.

+<h2 id="about">About the Code of Conduct</h2>
+
+<h3 id="why">Why have a Code of Conduct?</h3>
+
+<p>
+Online communities include people from many different backgrounds.
+The Go contributors are committed to providing a friendly, safe and welcoming
+environment for all, regardless of age, disability, gender, nationality,
+ethnicity, religion, sexuality, or similar personal characteristic.
+</p>
+
+<p>
+The first goal of the Code of Conduct is to specify a baseline standard
+of behavior so that people with different social values and communication
+styles can talk about Go effectively, productively, and respectfully.
+</p>
+
+<p>
+The second goal is to provide a mechanism for resolving conflicts in the
+community when they arise.
+</p>
+
+<p>
+The third goal of the Code of Conduct is to make our community welcoming to
+people from different backgrounds.
+Diversity is critical to the project; for Go to be successful, it needs
+contributors and users from all backgrounds.
+(See <a href="https://blog.golang.org/open-source">Go, Open Source, Community</a>.)
+</p>
+
+<p>
+With that said, a healthy community must allow for disagreement and debate.
+The Code of Conduct is not a mechanism for people to silence others with whom
+they disagree.
+</p>
+
+<h3 id="spaces">Where does the Code of Conduct apply?</h3>
+
+<p>
+If you participate in or contribute to the Go ecosystem in any way,
+you are encouraged to follow the Code of Conduct while doing so.
+</p>
+
+<p>
+Explicit enforcement of the Code of Conduct applies to the
+official forums operated by the Go project (“Go spaces”):
+</p>
+
+<ul>
+    <li>The official <a href="https://github.com/golang/">GitHub projects</a>
+        and <a href="https://go-review.googlesource.com/">code reviews</a>.
+    <li>The <a href="https://groups.google.com/group/golang-nuts">golang-nuts</a> and
+        <a href="https://groups.google.com/group/golang-dev">golang-dev</a> mailing lists.
+<li>The #go-nuts IRC channel on Freenode.
+</ul>
+
+<p>
+Other Go groups (such as conferences, meetups, and other unofficial forums) are
+encouraged to adopt this Code of Conduct. Those groups must provide their own
+moderators and/or working group (see below).
+</p>
+
+<h2 id="values">Gopher values</h2>
+
+<p>
+These are the values to which people in the Go community (“Gophers”) should aspire.
+</p>
+
+<ul>
+<li>Be friendly and welcoming
+<li>Be patient
+    <ul>
+    <li>Remember that people have varying communication styles and that not
+        everyone is using their native language.
+        (Meaning and tone can be lost in translation.)
+    </ul>
+<li>Be thoughtful
+    <ul>
+    <li>Productive communication requires effort.
+        Think about how your words will be interpreted.
+    <li>Remember that sometimes it is best to refrain entirely from commenting.
+    </ul>
+<li>Be respectful
+    <ul>
+    <li>In particular, respect differences of opinion.
+    </ul>
+<li>Be charitable
+    <ul>
+    <li>Interpret the arguments of others in good faith, do not seek to disagree.
+    <li>When we do disagree, try to understand why.
+    </ul>
+<li>Avoid destructive behavior:
+    <ul>
+    <li>Derailing: stay on topic; if you want to talk about something else,
+        start a new conversation.
+    <li>Unconstructive criticism: don't merely decry the current state of affairs;
+        offer—or at least solicit—suggestions as to how things may be improved.
+    <li>Snarking (pithy, unproductive, sniping comments)
+    <li>Discussing potentially offensive or sensitive issues;
+        this all too often leads to unnecessary conflict.
+    <li>Microaggressions: brief and commonplace verbal, behavioral and
+        environmental indignities that communicate hostile, derogatory or negative
+        slights and insults to a person or group.
+    </ul>
+</ul>
+
+<p>
+People are complicated.
+You should expect to be misunderstood and to misunderstand others;
+when this inevitably occurs, resist the urge to be defensive or assign blame.
+Try not to take offense where no offense was intended.
+Give people the benefit of the doubt.
+Even if the intent was to provoke, do not rise to it.
+It is the responsibility of <i>all parties</i> to de-escalate conflict when it arises.
+</p>
+
+<h2 id="unwelcome_behavior">Unwelcome behavior</h2>
+
+<p>
+These actions are explicitly forbidden in Go spaces:
+</p>
+
+<ul>
+<li>Insulting, demeaning, hateful, or threatening remarks.
+<li>Discrimination based on age, disability, gender, nationality, race,
+    religion, sexuality, or similar personal characteristic.
+<li>Bullying or systematic harassment.
+<li>Unwelcome sexual advances.
+<li>Incitement to any of these.
+</ul>
+
+<h2 id="moderation">Moderation</h2>
+
+<p>
+The Go spaces are not free speech venues; they are for discussion about Go.
+Each of these spaces have their own moderators.
+</p>
+
+<p>
+When using the official Go spaces you should act in the spirit of the “Gopher
+values”.
+If a reported conflict cannot be resolved amicably, the CoC Working Group
+may make a recommendation to the relevant forum moderators.
+</p>
+
+<p>
+CoC Working Group members and forum moderators are held to a higher standard than other community members.
+If a working group member or moderator creates an inappropriate situation, they
+should expect less leeway than others, and should expect to be removed from
+their position if they cannot adhere to the CoC.
+</p>
+
+<p>
+Complaints about working group member or moderator actions must be handled 
+using the reporting process below.
+</p>
+
+<h2 id="reporting">Reporting issues</h2>
+
+<p>
+The Code of Conduct Working Group is a group of people that represent the Go
+community. They are responsible for handling conduct-related issues.
+Their purpose is to de-escalate conflicts and try to resolve issues to the
+satisfaction of all parties. They are:
+</p>
+
+<ul>
+	<li>Aditya Mukerjee &lt;dev@chimeracoder.net&gt;
+	<li>Andrew Gerrand &lt;adg@golang.org&gt;
+	<li>Peggy Li &lt;peggyli.224@gmail.com&gt;
+	<li>Sarah Adams &lt;sadams.codes@gmail.com&gt;
+	<li>Steve Francia &lt;steve.francia@gmail.com&gt;
+	<li>Verónica López &lt;gveronicalg@gmail.com&gt;
+</ul>
+
+<p>
+If you encounter a conduct-related issue, you should report it to the
+Working Group using the process described below.
+<b>Do not</b> post about the issue publicly or try to rally sentiment against a
+particular individual or group.
+</p>
+
+<ul>
+<li>Mail <a href="mailto:conduct@golang.org">conduct@golang.org</a>.
+    <ul>
+    <li>Your message will reach the Working Group.
+    <li>Reports are confidential within the Working Group.
+    <li>You may contact a member of the group directly if you do not feel
+        comfortable contacting the group as a whole. That member will then raise
+        the issue with the Working Group as a whole, preserving the privacy of the
+        reporter (if desired).
+    <li>If your report concerns a member of the Working Group they will be recused
+        from Working Group discussions of the report.
+    <li>The Working Group will strive to handle reports with discretion and
+        sensitivity, to protect the privacy of the involved parties,
+        and to avoid conflicts of interest.
+    </ul>
+<li>You should receive a response within 48 hours (likely sooner).
+    (Should you choose to contact a single Working Group member,
+    it may take longer to receive a response.)
+<li>The Working Group will meet to review the incident and determine what happened.
+    <ul>
+    <li>With the permission of person reporting the incident, the Working Group
+        may reach out to other community members for more context.
+    </ul>
+<li>The Working Group will reach a decision as to how to act. These may include:
+    <ul>
+    <li>Nothing.
+    <li>Passing the report along to the offender.
+    <li>A recommendation of action to the relevant forum moderators.
+    </ul>
+<li>The Working Group will reach out to the original reporter to let them know
+    the decision.
+<li>Appeals to the decision may be made to the Working Group,
+    or to any of its members directly.
+</ul>
+
+<p>
+<b>Note that the goal of the Code of Conduct and the Working Group is to resolve
+conflicts in the most harmonious way possible.</b>
+We hope that in most cases issues may be resolved through polite discussion and
+mutual agreement.
+</p>
+
+<p>
+Changes to the Code of Conduct (including to the members of the Working Group)
+should be proposed using the
+<a href="https://golang.org/s/proposal-process">change proposal process</a>.
+</p>
+
+<h2 id="summary">Summary</h2>
+
+<ul>
+<li>Treat everyone with respect and kindness.
+<li>Be thoughtful in how you communicate.
+<li>Don’t be destructive or inflammatory.
+<li>If you encounter an issue, please mail <a href="mailto:conduct@golang.org">conduct@golang.org</a>.

+}-->
+
+<p>
+The Go project welcomes all contributors. The process of contributing
+to the Go project may be different than many projects you are used to.
+This document is intended as a guide to help you through the contribution
+process. This guide assumes you have a basic understanding of Git and Go.
+</p>
+
+<p>
+(Note that the <code>gccgo</code> frontend lives elsewhere;
+see <a href="gccgo_contribute.html">Contributing to gccgo</a>.)
+</p>
+
+<p>
+Sensitive security-related issues should be reported to <a href="mailto:security@golang.org">security@golang.org</a>.
+</p>
+
+<h1 id="contributor">Becoming a contributor</h1>
+
+<p>
+Before you can contribute to the Go project you need to setup a few prerequisites.
+The Go project uses <a href="https://www.gerritcodereview.com/">Gerrit</a>, an open
+source online tool, to perform all code reviews.
+Gerrit uses your email address as a unique identifier.
+The Go project contributing flow is currently configured to work only with Google Accounts.
+You must go through the following process <em>prior to contributing</em>.
+You only need to do this once per Google Account.
+</p>
+
+<h2 id="auth">Configure Git to use Gerrit</h2>
+<p>
+You'll need a web browser and a command line terminal.
+You should already have Git installed.
+</p>
+
+<p>
+Gerrit uses Google Accounts for authentication.
+If you don't have a Google Account, you can create an account which
+<a href="https://www.google.com/accounts/NewAccount">includes
+a new Gmail email account</a> or create an account associated
+<a href="https://accounts.google.com/SignUpWithoutGmail">with your existing
+email address</a>.
+</p>
+
+<h3>Step 1: Sign in to googlesource and generate a password</h3>
+
+<p>
+Visit <a href="https://go.googlesource.com">go.googlesource.com</a>
+and click on "Generate Password" in the page's top right menu bar.
+You will be redirected to accounts.google.com to sign in.
+</p>
+
+<h3>Step 2: Run the provided script</h3>
+<p>
+After signing in, you are taken to a page on go.googlesource.com with the title "Configure Git".
+This page contains a personalized script which when run locally will configure git
+to have your unique authentication key.
+This key is paired with one generated server side similar to how ssh keys work.
+</p>
+
+<p>
+Copy and run this script locally in your command line terminal.
+(On a Windows computer using cmd you should instead follow the instructions
+in the yellow box to run the command. If you are using git-bash use the same
+script as *nix.)
+</p>
+
+<p>
+Your secret authentication token is now in a <code>.gitcookie</code> file
+and Git is configured to use this file.
+</p>
+
+<h3 id="gerrit">Step 3: Register with Gerrit</h3>
+
+<p>
+Now that you have your authentication token, you need to register your
+account with Gerrit.
+To do this, visit <a href="https://go-review.googlesource.com/login/">
+go-review.googlesource.com/login/</a>.
+Sign in using the same Google Account you used above.
+</p>
+
+<h2 id="cla">Contributor License Agreement</h2>
+
+<h3 id="which_cla">Which CLA</h3>
+<p>
+Before sending your first change to the Go project
+you must have completed one of the following two CLAs.
+Which CLA you should sign depends on who owns the copyright to your work.
+</p>
+
+<ul>
+<li>
+If you are the copyright holder, you will need to agree to the
+<a href="https://developers.google.com/open-source/cla/individual">individual
+contributor license agreement</a>, which can be completed online.
+</li>
+<li>
+If your organization is the copyright holder, the organization
+will need to agree to the
+<a href="https://developers.google.com/open-source/cla/corporate">corporate
+contributor license agreement</a>.<br>
+</li>
+</ul>
+
+<p>
+<i>If the copyright holder for your contribution has already completed the
+agreement in connection with another Google open source project,
+it does not need to be completed again.</i>
+</p>
+
+<h3 id="signing_cla">Completing the CLA</h3>
+
+<p>
+You can see your currently signed agreements and sign new ones through the Gerrit
+interface.
+To do this, <a href="https://go-review.googlesource.com/login/">Log into Gerrit</a>,
+click your name in the upper-right, choose "Settings", then select "Agreements"
+from the topics on the left.
+If you do not have a signed agreement listed here,
+you can create one by clicking "New Contributor Agreement" and following the steps.
+</p>
+
+<p>
+If the copyright holder for the code you are submitting changes &mdash; for example,
+if you start contributing code on behalf of a new company &mdash; please send email
+to golang-dev and let us know, so that we can make sure an appropriate agreement is
+completed and update the <code>AUTHORS</code> file.

+
+<h2 id="git-codereview">Setting up Git for submission to Gerrit</h2>
+<p>
+Changes to Go must be reviewed before they are accepted, no matter who makes the change.
+A custom git command called <code>git-codereview</code>, discussed below,
+helps manage the code review process through a Google-hosted
+<a href="https://go-review.googlesource.com/">instance</a> Gerrit.
+</p>
+
+<h3 id="git-codereview_install">Install the git-codereview command</h3>
+<p>
+Install the <code>git-codereview</code> command by running,
+</p>
+
+<pre>
+$ go get -u golang.org/x/review/git-codereview
+</pre>
+
+<p>
+Make sure <code>git-codereview</code> is installed in your shell path, so that the
+<code>git</code> command can find it. Check that
+</p>
+
+<pre>
+$ git codereview help
+</pre>
+
+<p>
+prints help text, not an error.
+</p>
+
+<p>
+On Windows, when using git-bash you must make sure that
+<code>git-codereview.exe</code> is in your git exec-path.
+Run <code>git --exec-path</code> to discover the right location then create a
+symbolic link or simply copy the executible from $GOPATH/bin to this directory.
+</p>
+
+<p>
+<b>Note to Git aficionados:</b>
+The <code>git-codereview</code> command is not required to
+upload and manage Gerrit code reviews.
+For those who prefer plain Git, the text below gives the Git equivalent of
+each git-codereview command.
+</p>
+
+<p>
+If you do use plain Git, note that you still need the commit hooks that the
+git-codereview command configures; those hooks add a Gerrit
+<code>Change-Id</code> line to the commit message and check that all Go source
+files have been formatted with gofmt.
+Even if you intend to use plain Git for
+daily work, install the hooks in a new Git checkout by running
+<code>git-codereview</code> <code>hooks</code>.
+</p>
+
+<p>
+The workflow described below assumes a single change per branch.
+It is also possible to prepare a sequence of (usually related) changes in a single branch.
+See the <a href="https://golang.org/x/review/git-codereview">git-codereview documentation</a> for details.

+
+<h3 id="git-config">Set up git aliases</h3>
+
+<p>
+The <code>git-codereview</code> command can be run directly from the shell
+by typing, for instance,
+</p>
+
+<pre>
+$ git codereview sync
+</pre>
+
+<p>
+but it is more convenient to set up aliases for <code>git-codereview</code>'s own
+subcommands, so that the above becomes,
+</p>
+
+<pre>
+$ git sync
+</pre>
+
+<p>
+The <code>git-codereview</code> subcommands have been chosen to be distinct from
+Git's own, so it's safe to do so.
+</p>
+
+<p>
+The aliases are optional, but in the rest of this document we will assume
+they are installed.
+To install them, copy this text into your Git configuration file
+(usually <code>.gitconfig</code> in your home directory):
+</p>
+
+<pre>
+[alias]
+	change = codereview change
+	gofmt = codereview gofmt
+	mail = codereview mail
+	pending = codereview pending
+	submit = codereview submit
+	sync = codereview sync

+
+<h2 id="Design">Discuss your design</h2>
+
+<p>
+The project welcomes submissions but please let everyone know what
+you're working on if you want to change or add to the Go repositories.
+</p>
+
+<p>
+Before undertaking to write something new for the Go project,
+please <a href="https://golang.org/issue/new">file an issue</a>
+(or claim an <a href="https://golang.org/issues">existing issue</a>).
+Significant changes must go through the
+<a href="https://golang.org/s/proposal-process">change proposal process</a>
+before they can be accepted.
+</p>
+
+<p>
+This process gives everyone a chance to validate the design,
+helps prevent duplication of effort,
+and ensures that the idea fits inside the goals for the language and tools.
+It also checks that the design is sound before code is written;
+the code review tool is not the place for high-level discussions.
+</p>
+
+<p>
+When planning work, please note that the Go project follows a <a
+href="https://golang.org/wiki/Go-Release-Cycle">six-month development cycle</a>.
+The latter half of each cycle is a three-month feature freeze during
+which only bug fixes and doc updates are accepted. New contributions can be
+sent during a feature freeze but will not be accepted until the freeze thaws.
+</p>
+
+<h2 id="making_a_change">Making a change</h2>
+
+<h3 id="checkout_go">Getting Go Source</h3>
+<p>
+First you need to have a local copy of the source checked out from the correct
+repository.
+As Go builds Go you will also likely need to have a working version
+of Go installed (some documentation changes may not need this).
+This should be a recent version of Go and can be obtained via any package or
+binary distribution or you can build it from source.
+</p>
+
+<p>
+You should checkout the Go source repo anywhere you want as long as it's
+outside of your $GOPATH.
+Go to a directory where you want the source to appear and run the following
+command in a terminal.
+</p>
+
+<pre><code>
+$ git clone https://go.googlesource.com/go
+$ cd go
+</code></pre>
+
+<h3 id="master">Contributing to the main Go tree</h3>
+
+<p>
+Most Go installations use a release branch, but new changes should
+only be made based on the master branch. <br>
+(They may be applied later to a release branch as part of the release process,
+but most contributors won't do this themselves.)
+Before making a change, make sure you start on the master branch:
+</p>
+
+<pre>
+$ git checkout master
+$ git sync
+</pre>
+
+<p>
+(In Git terms, <code>git</code> <code>sync</code> runs
+<code>git</code> <code>pull</code> <code>-r</code>.)
+</p>
+
+<h3 id="subrepos">Contributing to subrepositories (golang.org/x/...)</h3>
+
+<p>
+If you are contributing a change to a subrepository, obtain the
+Go package using <code>go get</code>. For example, to contribute
+to <code>golang.org/x/oauth2</code>, check out the code by running:
+</p>
+
+<pre>
+$ go get -d golang.org/x/oauth2/...
+</pre>
+
+<p>
+Then, change your directory to the package's source directory
+(<code>$GOPATH/src/golang.org/x/oauth2</code>).
+</p>
+
+<h3 id="change">Make your changes</h3>
+
+<p>
+The entire checked-out tree is editable.
+Make your changes as you see fit ensuring that you create appropriate
+tests along with your changes. Test your changes as you go.
+</p>
+
+<h3 id="copyright">Copyright</h3>
+
+<p>
+Files in the Go repository don't list author names, both to avoid clutter
+and to avoid having to keep the lists up to date.
+Instead, your name will appear in the
+<a href="https://golang.org/change">change log</a> and in the <a
+href="/CONTRIBUTORS"><code>CONTRIBUTORS</code></a> file and perhaps the <a
+href="/AUTHORS"><code>AUTHORS</code></a> file.
+These files are automatically generated from the commit logs perodically.
+The <a href="/AUTHORS"><code>AUTHORS</code></a> file defines who &ldquo;The Go
+Authors&rdquo;&mdash;the copyright holders&mdash;are.
+</p>
+
+<p>New files that you contribute should use the standard copyright header:</p>
+
+<pre>
+// Copyright 2017 The Go Authors. All rights reserved.
+// Use of this source code is governed by a BSD-style
+// license that can be found in the LICENSE file.
+</pre>
+
+<p>
+Files in the repository are copyright the year they are added.
+Do not update the copyright year on files that you change.
+</p>
+
+<h3 id="commit_changes">Commit your changes</h3>
+
+<p>
+Once you have edited files, you must tell Git that they have been modified.
+You must also tell Git about any files that are added, removed, or renamed files.
+These operations are done with the usual Git commands,
+<code>git</code> <code>add</code>,
+<code>git</code> <code>rm</code>,
+and
+<code>git</code> <code>mv</code>.
+</p>
+
+<p>
+Once you have the changes queued up, you will want to commit them.
+In the Go contribution workflow this is done with a `git change` command,
+which creates a local branch and commits the changes directly to that local branch.
+</p>
+
+<pre>
+$ git change <i>&lt;branch&gt;</i>
+</pre>
+
+<p>
+The name <i>&lt;branch&gt;</i> is an arbitrary one you choose to identify the
+local branch containing your changes and will not be used elsewhere.
+This is an offline operation and nothing will be sent to the server yet.
+</p>
+
+<p>
+(In Git terms, <code>git</code> <code>change</code> <code>&lt;branch&gt;</code>
+runs <code>git</code> <code>checkout</code> <code>-b</code> <code>branch</code>,
+then <code>git</code> <code>branch</code> <code>--set-upstream-to</code> <code>origin/master</code>,
+then <code>git</code> <code>commit</code>.)
+</p>
+
+<p>
+As the `git commit` is the final step, Git will open an editor to ask for a
+commit message.
+(It uses the editor named by the <code>$EDITOR</code> environment variable,
+<code>vi</code> by default.)
+
+The file will look like:
+</p>
+
+<pre>
+
+# Please enter the commit message for your changes. Lines starting
+# with '#' will be ignored, and an empty message aborts the commit.
+# On branch foo
+# Changes not staged for commit:
+#	modified:   editedfile.go
+#
+</pre>
+
+<p>
+At the beginning of this file is a blank line; replace it
+with a thorough description of your change.
+The first line of the change description is conventionally a one-line
+summary of the change, prefixed by the primary affected package,
+and is used as the subject for code review email.
+It should complete the sentence "This change modifies Go to _____."
+The rest of the description elaborates and should provide context for the
+change and explain what it does.
+Write in complete sentences with correct punctuation, just like
+for your comments in Go.
+If there is a helpful reference, mention it here.
+If you've fixed an issue, reference it by number with a # before it.
+</p>
+
+<p>
+After editing, the template might now read:
+</p>
+
+<pre>
+math: improve Sin, Cos and Tan precision for very large arguments
+
+The existing implementation has poor numerical properties for
+large arguments, so use the McGillicutty algorithm to improve
+accuracy above 1e10.
+
+The algorithm is described at http://wikipedia.org/wiki/McGillicutty_Algorithm
+
+Fixes #159
+
+# Please enter the commit message for your changes. Lines starting
+# with '#' will be ignored, and an empty message aborts the commit.
+# On branch foo
+# Changes not staged for commit:
+#	modified:   editedfile.go
+#
+</pre>
+
+<p>
+The commented section of the file lists all the modified files in your client.
+It is best to keep unrelated changes in different change lists,
+so if you see a file listed that should not be included, abort
+the command and move that file to a different branch.
+</p>
+
+<p>
+The special notation "Fixes #159" associates the change with issue 159 in the
+<a href="https://golang.org/issue/159">Go issue tracker</a>.
+When this change is eventually applied, the issue
+tracker will automatically mark the issue as fixed.
+(There are several such conventions, described in detail in the
+<a href="https://help.github.com/articles/closing-issues-via-commit-messages/">GitHub Issue Tracker documentation</a>.)
+</p>
+
+<p>
+Once you have finished writing the commit message,
+save the file and exit the editor.
+</p>
+
+<p>
+You must have the $EDITOR environment variable set properly and working properly (exiting cleanly)
+for this operation to succeed.
+If you run into any issues at this step, it's likely your editor isn't exiting cleanly.
+Try setting a different editor in your $EDITOR environment variable.
+</p>
+
+<p>
+If you wish to do more editing, re-stage your changes using
+<code>git</code> <code>add</code>, and then run
+</p>
+
+<pre>
+$ git change
+</pre>
+
+<p>
+to update the change description and incorporate the staged changes.
+The change description contains a <code>Change-Id</code> line near the bottom,
+added by a Git commit hook during the initial
+<code>git</code> <code>change</code>.
+That line is used by Gerrit to match successive uploads of the same change.
+Do not edit or delete it.
+</p>
+
+<p>
+(In Git terms, <code>git</code> <code>change</code> with no branch name
+runs <code>git</code> <code>commit</code> <code>--amend</code>.)
+</p>
+
+<h3 id="Testing">Testing</h3>
+
+<p>
+You've <a href="code.html">written and tested your code</a>, but
+before sending code out for review, run all the tests for the whole
+tree to make sure the changes don't break other packages or programs:
+</p>
+
+<pre>
+$ cd go/src
+$ ./all.bash
+</pre>
+
+<p>
+(To build under Windows use <code>all.bat</code>.)
+</p>
+
+<p>
+After running for a while, the command should print
+</p>
+
+<pre>
+"ALL TESTS PASSED".
+</pre>
+
+<h3 id="mail">Send the change for review</h3>
+
+<p>
+Once the change is ready, send it for review.
+This is similar to a <code>git push</code> in a GitHub style workflow.
+This is done via the mail alias setup earlier which despite its name, doesn't
+directly mail anything, it simply sends the change to Gerrit via git push.
+</p>
+
+<pre>
+$ git mail
+</pre>
+
+<p>
+(In Git terms, <code>git</code> <code>mail</code> pushes the local committed
+changes to Gerrit using <code>git</code> <code>push</code> <code>origin</code>
+<code>HEAD:refs/for/master</code>.)
+</p>
+
+<p>
+If your change relates to an open issue, please add a comment to the issue
+announcing your proposed fix, including a link to your CL.
+</p>
+
+<p>
+The code review server assigns your change an issue number and URL,
+which <code>git</code> <code>mail</code> will print, something like:
+</p>
+
+<pre>
+remote: New Changes:
+remote:   https://go-review.googlesource.com/99999 math: improved Sin, Cos and Tan precision for very large arguments
+</pre>
+
+<h3>Troubleshooting</h3>
+
+<p>
+The most common way that the <code>git mail</code> command fails is because the
+email address used has not gone through the setup above.
+<br>
+If you see something like...
+</p>
+
+<pre>
+remote: Processing changes: refs: 1, done
+remote:
+remote: ERROR:  In commit ab13517fa29487dcf8b0d48916c51639426c5ee9
+remote: ERROR:  author email address XXXXXXXXXXXXXXXXXXX
+remote: ERROR:  does not match your user account.
+</pre>
+
+<p>
+You need to either add the email address listed to the CLA or set this repo to use
+another email address already approved.
+</p>
+
+<p>
+First let's change the email address for this repo so this doesn't happen again.
+You can change your email address for this repo with the following command:
+</p>
+
+<pre>
+$ git config user.email email@address.com
+</pre>
+
+<p>
+Then change the previous commit to use this alternative email address.
+You can do that with:
+</p>
+
+<pre>
+$ git commit --amend --author="Author Name &lt;email@address.com&gt;"
+</pre>
+
+<p>
+Finally try to resend with:
+</p>
+
+<pre>
+$ git mail
+</pre>
+
+<h3 id="cc">Specifying a reviewer / CCing others</h3>
+
+<p>
+Unless explicitly told otherwise, such as in the discussion leading
+up to sending in the change list, it's better not to specify a reviewer.
+All changes are automatically CC'ed to the
+<a href="https://groups.google.com/group/golang-codereviews">golang-codereviews@googlegroups.com</a>
+mailing list. If this is your first ever change, there may be a moderation
+delay before it appears on the mailing list, to prevent spam.
+</p>
+
+<p>
+You can specify a reviewer or CC interested parties
+using the <code>-r</code> or <code>-cc</code> options.
+Both accept a comma-separated list of email addresses:
+</p>
+
+<pre>
+$ git mail -r joe@golang.org -cc mabel@example.com,math-nuts@swtch.com
+</pre>
+
+<h2 id="review">Going through the review process</h2>
+
+<p>
+Running <code>git</code> <code>mail</code> will send an email to you and the
+reviewers asking them to visit the issue's URL and make comments on the change.
+When done, the reviewer adds comments through the Gerrit user interface
+and clicks "Reply" to send comments back.
+You will receive a mail notification when this happens.
+You must reply through the web interface.
+(Unlike with the old Rietveld review system, replying by mail has no effect.)
+</p>
+
+<h3 id="revise">Revise and resend</h3>
+
+<p>
+The Go contribution workflow is optimized for iterative revisions based on
+feedback.
+It is rare that an initial contribution will be ready to be applied as is.
+As you revise your contribution and resend Gerrit will retain a history of
+all the changes and comments made in the single URL.
+</p>
+
+<p>
+You must respond to review comments through the web interface.
+(Unlike with the old Rietveld review system, responding by mail has no effect.)
+</p>
+
+<p>
+When you have revised the code and are ready for another round of review,
+stage those changes and use <code>git</code> <code>change</code> to update the
+commit.
+To send the update change list for another round of review,
+run <code>git</code> <code>mail</code> again.
+</p>
+
+<p>
+The reviewer can comment on the new copy, and the process repeats.
+The reviewer approves the change by giving it a positive score
+(+1 or +2) and replying <code>LGTM</code>: looks good to me.
+</p>
+
+<p>
+You can see a list of your pending changes by running <code>git</code>
+<code>pending</code>, and switch between change branches with <code>git</code>
+<code>change</code> <code><i>&lt;branch&gt;</i></code>.
+</p>
+
+<h3 id="sync">Synchronize your client</h3>
+
+<p>
+While you were working, others might have submitted changes to the repository.
+To update your local branch, run
+</p>
+
+<pre>
+$ git sync
+</pre>
+
+<p>
+(In git terms, <code>git</code> <code>sync</code> runs
+<code>git</code> <code>pull</code> <code>-r</code>.)
+</p>
+
+<h3 id="resolving_conflicts">Resolving Conflicts</h3>
+
+<p>
+If files you were editing have changed, Git does its best to merge the
+remote changes into your local changes.
+It may leave some files to merge by hand.
+</p>
+
+<p>
+For example, suppose you have edited <code>sin.go</code> but
+someone else has committed an independent change.
+When you run <code>git</code> <code>sync</code>,
+you will get the (scary-looking) output:
+
+<pre>
+$ git sync
+Failed to merge in the changes.
+Patch failed at 0023 math: improved Sin, Cos and Tan precision for very large arguments
+The copy of the patch that failed is found in:
+   /home/you/repo/.git/rebase-apply/patch
+
+When you have resolved this problem, run "git rebase --continue".
+If you prefer to skip this patch, run "git rebase --skip" instead.
+To check out the original branch and stop rebasing, run "git rebase --abort".
+</pre>
+
+<p>
+If this happens, run
+</p>
+
+<pre>
+$ git status
+</pre>
+
+<p>
+to see which files failed to merge.
+The output will look something like this:
+</p>
+
+<pre>
+rebase in progress; onto a24c3eb
+You are currently rebasing branch 'mcgillicutty' on 'a24c3eb'.
+  (fix conflicts and then run "git rebase --continue")
+  (use "git rebase --skip" to skip this patch)
+  (use "git rebase --abort" to check out the original branch)
+
+Unmerged paths:
+  (use "git reset HEAD &lt;file&gt;..." to unstage)
+  (use "git add &lt;file&gt;..." to mark resolution)
+
+	<i>both modified: sin.go</i>
+</pre>
+
+<p>
+The only important part in that transcript is the italicized "both modified"
+line: Git failed to merge your changes with the conflicting change.
+When this happens, Git leaves both sets of edits in the file,
+with conflicts marked by <code>&lt;&lt;&lt;&lt;&lt;&lt;&lt;</code> and
+<code>&gt;&gt;&gt;&gt;&gt;&gt;&gt;</code>.
+It is now your job to edit the file to combine them.
+Continuing the example, searching for those strings in <code>sin.go</code>
+might turn up:
+</p>
+
+<pre>
+	arg = scale(arg)
+&lt;&lt;&lt;&lt;&lt;&lt;&lt; HEAD
+	if arg &lt; 1e9 {
+=======
+	if arg &lt; 1e10 {
+&gt;&gt;&gt;&gt;&gt;&gt;&gt; mcgillicutty
+		largeReduce(arg)
+</pre>
+
+<p>
+Git doesn't show it, but suppose the original text that both edits
+started with was 1e8; you changed it to 1e10 and the other change to 1e9,
+so the correct answer might now be 1e10.
+First, edit the section to remove the markers and leave the correct code:
+</p>
+
+<pre>
+	arg = scale(arg)
+	if arg &lt; 1e10 {
+		largeReduce(arg)
+</pre>
+
+<p>
+Then tell Git that the conflict is resolved by running
+</p>
+
+<pre>
+$ git add sin.go
+</pre>
+
+<p>
+If you had been editing the file, say for debugging, but do not
+care to preserve your changes, you can run
+<code>git</code> <code>reset</code> <code>HEAD</code> <code>sin.go</code>
+to abandon your changes.
+Then run <code>git</code> <code>rebase</code> <code>--continue</code> to
+restore the change commit.
+</p>
+
+<h3 id="download">Reviewing code by others</h3>
+
+<p>
+As part of the review process reviewers can propose changes directly (in the
+GitHub workflow this would be someone else attaching commits to a pull request).
+
+You can import these changes proposed by someone else into your local Git repository.
+On the Gerrit review page, click the "Download ▼" link in the upper right
+corner, copy the "Checkout" command and run it from your local Git repo. It
+should look something like this:
+</p>
+
+<pre>
+$ git fetch https://go.googlesource.com/review refs/changes/21/1221/1 &amp;&amp; git checkout FETCH_HEAD
+</pre>
+
+<p>
+To revert, change back to the branch you were working in.
+</p>
+
+<h2 id="submit">Apply the change to the master branch</h2>
+
+<p>
+After the code has been <code>LGTM</code>'ed, an approver may
+apply it to the master branch using the Gerrit UI.
+There is a "Submit" button on the web page for the change
+that appears once the change is approved (marked +2).
+</p>
+
+<p>
+This checks the change into the repository.
+The change description will include a link to the code review,
+and the code review will be updated with a link to the change
+in the repository.
+Since the method used to integrate the changes is "Cherry Pick",
+the commit hashes in the repository will be changed by
+the "Submit" operation.

+This applies to the standard toolchain (the <code>gc</code> Go
+compiler and tools). Gccgo has native gdb support.
+Besides this overview you might want to consult the
+<a href="http://sourceware.org/gdb/current/onlinedocs/gdb/">GDB manual</a>.
+</i></p>
+
+<p>
+GDB does not understand Go programs well.
+The stack management, threading, and runtime contain aspects that differ
+enough from the execution model GDB expects that they can confuse
+the debugger, even when the program is compiled with gccgo.
+As a consequence, although GDB can be useful in some situations, it is
+not a reliable debugger for Go programs, particularly heavily concurrent ones.
+Moreover, it is not a priority for the Go project to address these issues, which
+are difficult.
+In short, the instructions below should be taken only as a guide to how
+to use GDB when it works, not as a guarantee of success.
+</p>
+
+<p>
+In time, a more Go-centric debugging architecture may be required.
+</p>
+
+<h2 id="Introduction">Introduction</h2>
+
+<p>
+When you compile and link your Go programs with the <code>gc</code> toolchain
+on Linux, Mac OS X, FreeBSD or NetBSD, the resulting binaries contain DWARFv3
+debugging information that recent versions (&gt;7.1) of the GDB debugger can
+use to inspect a live process or a core dump.
+</p>
+
+<p>
+Pass the <code>'-w'</code> flag to the linker to omit the debug information
+(for example, <code>go build -ldflags "-w" prog.go</code>).
+</p>
+
+<p>
+The code generated by the <code>gc</code> compiler includes inlining of
+function invocations and registerization of variables. These optimizations
+can sometimes make debugging with <code>gdb</code> harder. To disable them
+when debugging, pass the flags <code>-gcflags "-N -l"</code> to the
+<a href="/cmd/go"><code>go</code></a> command used to build the code being
+debugged.
+</p>
+
+<p>
+If you want to use gdb to inspect a core dump, you can trigger a dump
+on a program crash, on systems that permit it, by setting
+<code>GOTRACEBACK=crash</code> in the environment (see the
+<a href="/pkg/runtime/#hdr-Environment_Variables"> runtime package
+documentation</a> for more info).

+
+<p>
+A recent extension mechanism to GDB allows it to load extension scripts for a
+given binary. The tool chain uses this to extend GDB with a handful of
+commands to inspect internals of the runtime code (such as goroutines) and to
+pretty print the built-in map, slice and channel types.
+</p>
+
+<ul>
+<li>
+Pretty printing a string, slice, map, channel or interface:
+<pre>(gdb) <b>p <i>var</i></b></pre>
+</li>
+<li>
+A $len() and $cap() function for strings, slices and maps:
+<pre>(gdb) <b>p $len(<i>var</i>)</b></pre>
+</li>
+<li>
+A function to cast interfaces to their dynamic types:
+<pre>(gdb) <b>p $dtype(<i>var</i>)</b>
+(gdb) <b>iface <i>var</i></b></pre>
+<p class="detail"><b>Known issue:</b> GDB can’t automatically find the dynamic
+type of an interface value if its long name differs from its short name
+(annoying when printing stacktraces, the pretty printer falls back to printing
+the short type name and a pointer).</p>
+</li>
+<li>
+Inspecting goroutines:
+<pre>(gdb) <b>info goroutines</b>
+(gdb) <b>goroutine <i>n</i> <i>cmd</i></b>
+(gdb) <b>help goroutine</b></pre>
+For example:
+<pre>(gdb) <b>goroutine 12 bt</b></pre>
+</li>
+</ul>
+
+<p>
+If you'd like to see how this works, or want to extend it, take a look at <a
+href="/src/runtime/runtime-gdb.py">src/runtime/runtime-gdb.py</a> in
+the Go source distribution. It depends on some special magic types
+(<code>hash&lt;T,U&gt;</code>) and variables (<code>runtime.m</code> and
+<code>runtime.g</code>) that the linker
+(<a href="/src/cmd/link/internal/ld/dwarf.go">src/cmd/link/internal/ld/dwarf.go</a>) ensures are described in
+the DWARF code.
+</p>
+
+<p>
+If you're interested in what the debugging information looks like, run
+'<code>objdump -W a.out</code>' and browse through the <code>.debug_*</code>
+sections.
+</p>
+
+
+<h3 id="Known_Issues">Known Issues</h3>
+
+<ol>
+<li>String pretty printing only triggers for type string, not for types derived
+from it.</li>
+<li>Type information is missing for the C parts of the runtime library.</li>
+<li>GDB does not understand Go’s name qualifications and treats
+<code>"fmt.Print"</code> as an unstructured literal with a <code>"."</code>
+that needs to be quoted.  It objects even more strongly to method names of
+the form <code>pkg.(*MyType).Meth</code>.
+<li>All global variables are lumped into package <code>"main"</code>.</li>
+</ol>
+
+<h2 id="Tutorial">Tutorial</h2>
+
+<p>
+In this tutorial we will inspect the binary of the
+<a href="/pkg/regexp/">regexp</a> package's unit tests. To build the binary,
+change to <code>$GOROOT/src/regexp</code> and run <code>go test -c</code>.
+This should produce an executable file named <code>regexp.test</code>.
+</p>
+
+
+<h3 id="Getting_Started">Getting Started</h3>
+
+<p>
+Launch GDB, debugging <code>regexp.test</code>:
+</p>
+
+<pre>
+$ <b>gdb regexp.test</b>
+GNU gdb (GDB) 7.2-gg8
+Copyright (C) 2010 Free Software Foundation, Inc.
+License GPLv  3+: GNU GPL version 3 or later &lt;http://gnu.org/licenses/gpl.html&gt;

+
+Reading symbols from  /home/user/go/src/regexp/regexp.test...
+done.
+Loading Go Runtime support.
+(gdb) 
+</pre>
+
+<p>
+The message <code>"Loading Go Runtime support"</code> means that GDB loaded the
+extension from <code>$GOROOT/src/runtime/runtime-gdb.py</code>.
+</p>
+
+<p>
+To help GDB find the Go runtime sources and the accompanying support script,
+pass your <code>$GOROOT</code> with the <code>'-d'</code> flag:
+</p>
+
+<pre>
+$ <b>gdb regexp.test -d $GOROOT</b>
+</pre>
+
+<p>
+If for some reason GDB still can't find that directory or that script, you can load
+it by hand by telling gdb (assuming you have the go sources in
+<code>~/go/</code>):
+</p>
+
+<pre>
+(gdb) <b>source ~/go/src/runtime/runtime-gdb.py</b>
+Loading Go Runtime support.
+</pre>
+
+<h3 id="Inspecting_the_source">Inspecting the source</h3>
+
+<p>
+Use the <code>"l"</code> or <code>"list"</code> command to inspect source code.
+</p>
+
+<pre>
+(gdb) <b>l</b>
+</pre>
+
+<p>
+List a specific part of the source parametrizing <code>"list"</code> with a
+function name (it must be qualified with its package name).
+</p>
+
+<pre>
+(gdb) <b>l main.main</b>
+</pre>
+
+<p>
+List a specific file and line number:
+</p>
+
+<pre>
+(gdb) <b>l regexp.go:1</b>
+(gdb) <i># Hit enter to repeat last command. Here, this lists next 10 lines.</i>
+</pre>
+
+
+<h3 id="Naming">Naming</h3>
+
+<p>
+Variable and function names must be qualified with the name of the packages
+they belong to. The <code>Compile</code> function from the <code>regexp</code>
+package is known to GDB as <code>'regexp.Compile'</code>. 
+</p>
+
+<p>
+Methods must be qualified with the name of their receiver types. For example,
+the <code>*Regexp</code> type’s <code>String</code> method is known as
+<code>'regexp.(*Regexp).String'</code>.
+</p>
+
+<p>
+Variables that shadow other variables are magically suffixed with a number in the debug info.
+Variables referenced by closures will appear as pointers magically prefixed with '&amp;'.

+
+<h3 id="Setting_breakpoints">Setting breakpoints</h3>
+
+<p>
+Set a breakpoint at the <code>TestFind</code> function:
+</p>
+

+The command <code>info locals</code> lists all variables local to the function and their values, but is a bit
+dangerous to use, since it will also try to print uninitialized variables. Uninitialized slices may cause gdb to try
+to print arbitrary large arrays.

+</p>
+
+<pre>
+(gdb) <b>info args</b>
+t = 0xf840688b60
+</pre>
+
+<p>
+When printing the argument, notice that it’s a pointer to a
+<code>Regexp</code> value. Note that GDB has incorrectly put the <code>*</code>
+on the right-hand side of the type name and made up a 'struct' keyword, in traditional C style.
+</p>

+That <code>struct hchan&lt;*testing.T&gt;</code> is the
+runtime-internal representation of a channel. It is currently empty,
+or gdb would have pretty-printed its contents.

+
+<h3 id="Pretty_Printing">Pretty Printing</h3>
+
+<p>
+GDB's pretty printing mechanism is triggered by regexp matches on type names.  An example for slices:
+</p>
+
+<pre>
+(gdb) <b>p utf</b>
+$22 =  []uint8 = {0 '\000', 0 '\000', 0 '\000', 0 '\000'}
+</pre>
+
+<p>
+Since slices, arrays and strings are not C pointers, GDB can't interpret the subscripting operation for you, but
+you can look inside the runtime representation to do that (tab completion helps here):
+</p>
+<pre>
+
+(gdb) <b>p slc</b>
+$11 =  []int = {0, 0}
+(gdb) <b>p slc-&gt;</b><i>&lt;TAB&gt;</i>
+array  slc    len    
+(gdb) <b>p slc->array</b>
+$12 = (int *) 0xf84057af00
+(gdb) <b>p slc->array[1]</b>
+$13 = 0</pre>
+
+
+
+<p>
+The extension functions $len and $cap work on strings, arrays and slices:
+</p>
+
+<pre>
+(gdb) <b>p $len(utf)</b>
+$23 = 4
+(gdb) <b>p $cap(utf)</b>
+$24 = 4
+</pre>
+
+<p>
+Channels and maps are 'reference' types, which gdb shows as pointers to C++-like types <code>hash&lt;int,string&gt;*</code>.  Dereferencing will trigger prettyprinting
+</p>
+
+<p>
+Interfaces are represented in the runtime as a pointer to a type descriptor and a pointer to a value.  The Go GDB runtime extension decodes this and automatically triggers pretty printing for the runtime type.  The extension function <code>$dtype</code> decodes the dynamic type for you (examples are taken from a breakpoint at <code>regexp.go</code> line 293.)
+</p>
+
+<pre>
+(gdb) <b>p i</b>
+$4 = {str = "cbb"}
+(gdb) <b>whatis i</b>
+type = regexp.input
+(gdb) <b>p $dtype(i)</b>
+$26 = (struct regexp.inputBytes *) 0xf8400b4930
+(gdb) <b>iface i</b>
+regexp.input: struct regexp.inputBytes *

+See the <a href="release.html">Release History</a> page for notes on recent releases.
+</p>
+
+<h2 id="r60">r60 (released 2011/09/07)</h2>
+
+<p>
+The r60 release corresponds to 
+<code><a href="weekly.html#2011-08-17">weekly.2011-08-17</a></code>.
+This section highlights the most significant changes in this release.
+For a more detailed summary, see the
+<a href="weekly.html#2011-08-17">weekly release notes</a>.
+For complete information, see the
+<a href="//code.google.com/p/go/source/list?r=release-branch.r60">Mercurial change list</a>.
+</p>
+
+<h3 id="r60.lang">Language</h3>
+
+<p>
+An "else" block is now required to have braces except if the body of the "else"
+is another "if". Since gofmt always puts those braces in anyway,
+gofmt-formatted programs will not be affected.
+To fix other programs, run gofmt.
+</p>
+
+<h3 id="r60.pkg">Packages</h3>
+
+<p>
+<a href="/pkg/http/">Package http</a>'s URL parsing and query escaping code
+(such as <code>ParseURL</code> and <code>URLEscape</code>) has been moved to
+the new <a href="/pkg/url/">url package</a>, with several simplifications to
+the names. Client code can be updated automatically with gofix.
+</p>
+
+<p>
+<a href="/pkg/image/">Package image</a> has had significant changes made to the
+<code>Pix</code> field of struct types such as
+<a href="/pkg/image/#RGBA">image.RGBA</a> and
+<a href="/pkg/image/#NRGBA">image.NRGBA</a>.
+The <a href="/pkg/image/#Image">image.Image</a> interface type has not changed,
+though, and you should not need to change your code if you don't explicitly
+refer to <code>Pix</code> fields. For example, if you decode a number of images
+using the <a href="/pkg/image/jpeg/">image/jpeg</a> package, compose them using
+<a href="/pkg/image/draw/">image/draw</a>, and then encode the result using
+<a href="/pkg/img/png">image/png</a>, then your code should still work as
+before.
+If your code <i>does</i> refer to <code>Pix</code> fields see the 
+<a href="/doc/devel/weekly.html#2011-07-19">weekly.2011-07-19</a>
+snapshot notes for how to update your code.
+</p>
+
+<p>
+<a href="/pkg/template/">Package template</a> has been replaced with a new
+templating package (formerly <code>exp/template</code>). The original template
+package is still available as <a href="/pkg/old/template/">old/template</a>.
+The <code>old/template</code> package is deprecated and will be removed.
+The Go tree has been updated to use the new template package. We encourage
+users of the old template package to switch to the new one. Code that uses
+<code>template</code> or <code>exp/template</code> will need to change its
+import lines to <code>"old/template"</code> or <code>"template"</code>,
+respectively.
+</p>
+
+<h3 id="r60.cmd">Tools</h3>
+
+<p>
+<a href="/cmd/goinstall/">Goinstall</a> now uses a new tag selection scheme.
+When downloading or updating, goinstall looks for a tag or branch with the
+<code>"go."</code> prefix that corresponds to the local Go version. For Go
+<code>release.r58</code> it looks for <code>go.r58</code>. For
+<code>weekly.2011-06-03</code> it looks for <code>go.weekly.2011-06-03</code>.
+If the specific <code>go.X</code> tag or branch is not found, it chooses the
+closest earlier version. If an appropriate tag or branch is found, goinstall
+uses that version of the code. Otherwise it uses the default version selected
+by the version control system. Library authors are encouraged to use the
+appropriate tag or branch names in their repositories to make their libraries
+more accessible.
+</p>
+
+<h3 id="r60.minor">Minor revisions</h3>
+
+<p>
+r60.1 includes a 
+<a href="//golang.org/change/1824581bf62d">linker
+fix</a>, a pair of
+<a href="//golang.org/change/9ef4429c2c64">goplay</a>
+<a href="//golang.org/change/d42ed8c3098e">fixes</a>,
+and a <code>json</code> package

+a new
+<a href="//golang.org/change/4f0e6269213f">struct tag
+option</a>.
+</p>
+
+<p>
+r60.2
+<a href="//golang.org/change/ff19536042ac">fixes</a>
+a memory leak involving maps.
+</p>
+
+<p>
+r60.3 fixes a
+<a href="//golang.org/change/01fa62f5e4e5">reflect bug</a>.
+</p>
+
+<h2 id="r59">r59 (released 2011/08/01)</h2>
+
+<p>
+The r59 release corresponds to 
+<code><a href="weekly.html#2011-07-07">weekly.2011-07-07</a></code>.
+This section highlights the most significant changes in this release.
+For a more detailed summary, see the

+<a href="//code.google.com/p/go/source/list?r=release-branch.r59">Mercurial change list</a>.
+</p>
+
+<h3 id="r59.lang">Language</h3>
+
+<p>
+This release includes a language change that restricts the use of
+<code>goto</code>.  In essence, a <code>goto</code> statement outside a block
+cannot jump to a label inside that block. Your code may require changes if it
+uses <code>goto</code>.
+See <a href="//golang.org/change/dc6d3cf9279d">this
+changeset</a> for how the new rule affected the Go tree.
+</p>
+
+<h3 id="r59.pkg">Packages</h3>
+
+<p>
+As usual, <a href="/cmd/gofix/">gofix</a> will handle the bulk of the rewrites
+necessary for these changes to package APIs.
+</p>
+
+<p>
+<a href="/pkg/http">Package http</a> has a new
+<a href="/pkg/http/#FileSystem">FileSystem</a> interface that provides access
+to files. The <a href="/pkg/http/#FileServer">FileServer</a> helper now takes a
+<code>FileSystem</code> argument instead of an explicit file system root. By
+implementing your own <code>FileSystem</code> you can use the
+<code>FileServer</code> to serve arbitrary data.
+</p>
+
+<p>
+<a href="/pkg/os/">Package os</a>'s <code>ErrorString</code> type has been
+hidden. Most uses of <code>os.ErrorString</code> can be replaced with
+<a href="/pkg/os/#NewError">os.NewError</a>.
+</p>
+
+<p>
+<a href="/pkg/reflect/">Package reflect</a> supports a new struct tag scheme
+that enables sharing of struct tags between multiple packages.
+In this scheme, the tags must be of the form:
+</p>
+<pre>
+	`key:"value" key2:"value2"`
+</pre>

+The <a href="/pkg/reflect/#StructField">StructField</a> type's Tag field now

+<code>SplitN</code> is the same as the old <code>Split</code>.
+The new <code>Split</code> is equivalent to <code>SplitN</code> with a final

+
+<a href="/pkg/image/draw/">Package image/draw</a>'s

+</p>
+
+<h3 id="r58.pkg">Packages</h3>
+
+<p>
+As usual, <a href="/cmd/gofix/">gofix</a> will handle the bulk of the rewrites
+necessary for these changes to package APIs.
+</p>
+
+<p>
+<a href="/pkg/http/">Package http</a> drops the <code>finalURL</code> return
+value from the <a href="/pkg/http/#Client.Get">Client.Get</a> method. The value
+is now available via the new <code>Request</code> field on <a
+href="/pkg/http/#Response">http.Response</a>.
+Most instances of the type map[string][]string in have been
+replaced with the new <a href="/pkg/http/#Values">Values</a> type.
+</p>
+
+<p>
+<a href="/pkg/exec/">Package exec</a> has been redesigned with a more
+convenient and succinct API.
+</p>
+
+<p>
+<a href="/pkg/strconv/">Package strconv</a>'s <a href="/pkg/strconv/#Quote">Quote</a>
+function now escapes only those Unicode code points not classified as printable
+by <a href="/pkg/unicode/#IsPrint">unicode.IsPrint</a>.
+Previously Quote would escape all non-ASCII characters.
+This also affects the <a href="/pkg/fmt/">fmt</a> package's <code>"%q"</code>
+formatting directive. The previous quoting behavior is still available via
+strconv's new <a href="/pkg/strconv/#QuoteToASCII">QuoteToASCII</a> function.   
+</p>
+
+<p>
+<a href="/pkg/os/signal/">Package os/signal</a>'s
+<a href="/pkg/os/#Signal">Signal</a> and 
+<a href="/pkg/os/#UnixSignal">UnixSignal</a> types have been moved to the
+<a href="/pkg/os/">os</a> package.
+</p>
+
+<p>
+<a href="/pkg/image/draw/">Package image/draw</a> is the new name for
+<code>exp/draw</code>. The GUI-related code from <code>exp/draw</code> is now
+located in the <a href="/pkg/exp/gui/">exp/gui</a> package.
+</p>
+
+<h3 id="r58.cmd">Tools</h3>
+
+<p>
+<a href="/cmd/goinstall/">Goinstall</a> now observes the GOPATH environment
+variable to build and install your own code and external libraries outside of
+the Go tree (and avoid writing Makefiles).
+</p>
+
+
+<h3 id="r58.minor">Minor revisions</h3>
+
+<p>r58.1 adds 
+<a href="//golang.org/change/293c25943586">build</a> and
+<a href="//golang.org/change/bf17e96b6582">runtime</a>
+changes to make Go run on OS X 10.7 Lion.

+
+<h2 id="r57">r57 (released 2011/05/03)</h2>

+<p>
+The r57 release corresponds to

+with additional bug fixes.
+This section highlights the most significant changes in this release.

+</p>
+
+<p>The new <a href="/cmd/gofix">gofix</a> tool finds Go programs that use old APIs and rewrites them to use
+newer ones.  After you update to a new Go release, gofix helps make the
+necessary changes to your programs. Gofix will handle the http, os, and syscall
+package changes described below, and we will update the program to keep up with
+future changes to the libraries. 
+Gofix can’t
+handle all situations perfectly, so read and test the changes it makes before
+committing them.
+See <a href="//blog.golang.org/2011/04/introducing-gofix.html">the gofix blog post</a> for more
+information.</p>
+
+<h3 id="r57.lang">Language</h3>
+
+<p>
+<a href="/doc/go_spec.html#Receive_operator">Multiple assignment syntax</a> replaces the <code>closed</code> function.
+The syntax for channel
+receives allows an optional second assigned value, a boolean value
+indicating whether the channel is closed. This code:
+</p>
+
+<pre>
+	v := &lt;-ch
+	if closed(ch) {
+		// channel is closed
+	}
+</pre>
+
+<p>should now be written as:</p>
+
+<pre>
+	v, ok := &lt;-ch
+	if !ok {
+		// channel is closed
+	}
+</pre>
+
+<p><a href="/doc/go_spec.html#Label_scopes">Unused labels are now illegal</a>, just as unused local variables are.</p>
+
+<h3 id="r57.pkg">Packages</h3>
+
+<p>
+<a href="/pkg/gob/">Package gob</a> will now encode and decode values of types that implement the
+<a href="/pkg/gob/#GobEncoder">GobEncoder</a> and
+<a href="/pkg/gob/#GobDecoder">GobDecoder</a> interfaces. This allows types with unexported
+fields to transmit self-consistent descriptions; examples include 
+<a href="/pkg/big/#Int.GobDecode">big.Int</a> and <a href="/pkg/big/#Rat.GobDecode">big.Rat</a>.
+</p>
+
+<p>
+<a href="/pkg/http/">Package http</a> has been redesigned.
+For clients, there are new
+<a href="/pkg/http/#Client">Client</a> and <a href="/pkg/http/#Transport">Transport</a>
+abstractions that give more control over HTTP details such as headers sent
+and redirections followed.  These abstractions make it easy to implement
+custom clients that add functionality such as <a href="//code.google.com/p/goauth2/source/browse/oauth/oauth.go">OAuth2</a>.
+For servers, <a href="/pkg/http/#ResponseWriter">ResponseWriter</a>
+has dropped its non-essential methods.
+The Hijack and Flush methods are no longer required;
+code can test for them by checking whether a specific value implements
+<a href="/pkg/http/#Hijacker">Hijacker</a> or <a href="/pkg/http/#Flusher">Flusher</a>.
+The RemoteAddr and UsingTLS methods are replaced by <a href="/pkg/http/#Request">Request</a>'s
+RemoteAddr and TLS fields.
+The SetHeader method is replaced by a Header method;
+its result, of type <a href="/pkg/http/#Header">Header</a>,
+implements Set and other methods.
+</p>
+
+<p>
+<a href="/pkg/net/">Package net</a>
+drops the <code>laddr</code> argument from <a href="/pkg/net/#Conn.Dial">Dial</a>
+and drops the <code>cname</code> return value
+from <a href="/pkg/net/#LookupHost">LookupHost</a>.
+The implementation now uses <a href="/cmd/cgo/">cgo</a> to implement
+network name lookups using the C library getaddrinfo(3)
+function when possible.  This ensures that Go and C programs
+resolve names the same way and also avoids the OS X 
+application-level firewall.
+</p>
+
+<p>
+<a href="/pkg/os/">Package os</a>
+introduces simplified <a href="/pkg/os/#File.Open">Open</a>
+and <a href="/pkg/os/#File.Create">Create</a> functions.
+The original Open is now available as <a href="/pkg/os/#File.OpenFile">OpenFile</a>.
+The final three arguments to <a href="/pkg/os/#Process.StartProcess">StartProcess</a>
+have been replaced by a pointer to a <a href="/pkg/os/#ProcAttr">ProcAttr</a>.
+</p>
+
+<p>
+<a href="/pkg/reflect/">Package reflect</a> has been redesigned.
+<a href="/pkg/reflect/#Type">Type</a> is now an interface that implements
+all the possible type methods.
+Instead of a type switch on a Type <code>t</code>, switch on <code>t.Kind()</code>.
+<a href="/pkg/reflect/#Value">Value</a> is now a struct value that
+implements all the possible value methods.
+Instead of a type switch on a Value <code>v</code>, switch on <code>v.Kind()</code>.
+Typeof and NewValue are now called <a href="/pkg/reflect/#Type.TypeOf">TypeOf</a> and <a href="/pkg/reflect/#Value.ValueOf">ValueOf</a>
+To create a writable Value, use <code>New(t).Elem()</code> instead of <code>Zero(t)</code>.
+See <a href="//golang.org/change/843855f3c026">the change description</a>
+for the full details.
+The new API allows a more efficient implementation of Value
+that avoids many of the allocations required by the previous API.
+</p>
+
+<p>
+Remember that gofix will handle the bulk of the rewrites
+necessary for these changes to package APIs.
+</p>
+
+<h3 id="r57.cmd">Tools</h3>
+
+<p><a href="/cmd/gofix/">Gofix</a>, a new command, is described above.</p>
+
+<p>
+<a href="/cmd/gotest/">Gotest</a> is now a Go program instead of a shell script.
+The new <code>-test.short</code> flag in combination with package testing's Short function
+allows you to write tests that can be run in normal or &ldquo;short&rdquo; mode;
+all.bash runs tests in short mode to reduce installation time.
+The Makefiles know about the flag: use <code>make testshort</code>.
+</p>
+
+<p>
+The run-time support now implements CPU and memory profiling.
+Gotest's new 
+<a href="/cmd/gotest/"><code>-test.cpuprofile</code> and
+<code>-test.memprofile</code> flags</a> make it easy to
+profile tests.
+To add profiling to your web server, see the <a href="/pkg/http/pprof/">http/pprof</a>
+documentation.
+For other uses, see the <a href="/pkg/runtime/pprof/">runtime/pprof</a> documentation.

+Each major Go release obsoletes and ends support for the previous one.
+For example, if Go 1.5 has been released, then it is the current release
+and Go 1.4 and earlier are no longer supported.
+We fix critical problems in the current release as needed by issuing minor revisions
+(for example, Go 1.5.1, Go 1.5.2, and so on).
+</p>
+
+<p>
+As a special case, we issue minor revisions for critical security problems
+in both the current release and the previous release.
+For example, if Go 1.5 is the current release then we will issue minor revisions
+to fix critical security problems in both Go 1.4 and Go 1.5 as they arise.

+The Go programming language is an open source project to make programmers more
+productive.
+</p>
+
+<p>
+Go is expressive, concise, clean, and efficient. Its concurrency
+mechanisms make it easy to write programs that get the most out of multicore
+and networked machines, while its novel type system enables flexible and
+modular program construction. Go compiles quickly to machine code yet has the
+convenience of garbage collection and the power of run-time reflection. It's a
+fast, statically typed, compiled language that feels like a dynamically typed,
+interpreted language.

+One of Go's key design goals is code adaptability; that it should be easy to take a simple design and build upon it in a clean and natural way. In this talk Andrew Gerrand describes a simple "chat roulette" server that matches pairs of incoming TCP connections, and then use Go's concurrency mechanisms, interfaces, and standard library to extend it with a web interface and other features. While the function of the program changes dramatically, Go's flexibility preserves the original design as it grows.

+
+<h2>Introduction</h2>
+
+<p>
+These are some notes on contributing to the gccgo frontend for GCC.
+For information on contributing to parts of Go other than gccgo,
+see <a href="/doc/contribute.html">Contributing to the Go project</a>.  For
+information on building gccgo for yourself,
+see <a href="/doc/gccgo_install.html">Setting up and using gccgo</a>.
+For more of the gritty details on the process of doing development
+with the gccgo frontend,
+see <a href="https://go.googlesource.com/gofrontend/+/master/HACKING">the
+file HACKING</a> in the gofrontend repository.
+</p>
+
+<h2>Legal Prerequisites</h2>
+
+<p>
+You must follow the <a href="/doc/contribute.html#copyright">Go copyright
+rules</a> for all changes to the gccgo frontend and the associated
+libgo library.  Code that is part of GCC rather than gccgo must follow
+the general <a href="http://gcc.gnu.org/contribute.html">GCC
+contribution rules</a>.
+</p>
+
+<h2>Code</h2>
+
+<p>
+The master sources for the gccgo frontend may be found at
+<a href="http://go.googlesource.com/gofrontend">http://go.googlesource.com/gofrontend</a>.
+They are mirrored
+at <a href="http://github.com/golang/gofrontend">http://github.com/golang/gofrontend</a>.
+The master sources are not buildable by themselves, but only in
+conjunction with GCC (in the future, other compilers may be
+supported).  Changes made to the gccgo frontend are also applied to
+the GCC source code repository hosted at <code>gcc.gnu.org</code>.  In
+the <code>gofrontend</code> repository, the <code>go</code> directory
+is mirrored to the <code>gcc/go/gofrontend</code> directory in the GCC
+repository, and the <code>gofrontend</code> <code>libgo</code>
+directory is mirrored to the GCC <code>libgo</code> directory.  In
+addition, the <code>test</code> directory
+from <a href="//go.googlesource.com/go">the main Go repository</a>
+is mirrored to the <code>gcc/testsuite/go.test/test</code> directory
+in the GCC repository.
+</p>
+
+<p>
+Changes to these directories always flow from the master sources to
+the GCC repository.  The files should never be changed in the GCC
+repository except by changing them in the master sources and mirroring
+them.
+</p>
+
+<p>
+The gccgo frontend is written in C++.
+It follows the GNU and GCC coding standards for C++.
+In writing code for the frontend, follow the formatting of the
+surrounding code.
+Almost all GCC-specific code is not in the frontend proper and is
+instead in the GCC sources in the <code>gcc/go</code> directory.
+</p>
+
+<p>
+The run-time library for gccgo is mostly the same as the library
+in <a href="//go.googlesource.com/go">the main Go repository</a>.
+The library code in the Go repository is periodically merged into
+the <code>libgo/go</code> directory of the <code>gofrontend</code> and
+then the GCC repositories, using the shell
+script <code>libgo/merge.sh</code>.  Accordingly, most library changes
+should be made in the main Go repository.  The files outside
+of <code>libgo/go</code> are gccgo-specific; that said, some of the
+files in <code>libgo/runtime</code> are based on files
+in <code>src/runtime</code> in the main Go repository.
+</p>
+
+<h2>Testing</h2>
+
+<p>
+All patches must be tested.  A patch that introduces new failures is
+not acceptable.
+</p>
+
+<p>
+To run the gccgo test suite, run <code>make check-go</code> in your
+build directory.  This will run various tests
+under <code>gcc/testsuite/go.*</code> and will also run
+the <code>libgo</code> testsuite.  This copy of the tests from the
+main Go repository is run using the DejaGNU script found
+in <code>gcc/testsuite/go.test/go-test.exp</code>.
+</p>
+
+<p>
+Most new tests should be submitted to the main Go repository for later
+mirroring into the GCC repository.  If there is a need for specific
+tests for gccgo, they should go in
+the <code>gcc/testsuite/go.go-torture</code>
+or <code>gcc/testsuite/go.dg</code> directories in the GCC repository.
+</p>
+
+<h2>Submitting Changes</h2>
+
+<p>
+Changes to the Go frontend should follow the same process as for the
+main Go repository, only for the <code>gofrontend</code> project and
+the <code>gofrontend-dev@googlegroups.com</code> mailing list 
+rather than the <code>go</code> project and the
+<code>golang-dev@googlegroups.com</code> mailing list.  Those changes
+will then be merged into the GCC sources.

+<p>
+This document explains how to use gccgo, a compiler for
+the Go language.  The gccgo compiler is a new frontend
+for GCC, the widely used GNU compiler.  Although the
+frontend itself is under a BSD-style license, gccgo is
+normally used as part of GCC and is then covered by
+the <a href="http://www.gnu.org/licenses/gpl.html">GNU General Public
+License</a> (the license covers gccgo itself as part of GCC; it
+does not cover code generated by gccgo).
+</p>
+
+<p>
+Note that gccgo is not the <code>gc</code> compiler; see
+the <a href="/doc/install.html">Installing Go</a> instructions for that
+compiler.
+</p>
+
+<h2 id="Releases">Releases</h2>
+
+<p>
+The simplest way to install gccgo is to install a GCC binary release
+built to include Go support.  GCC binary releases are available from
+<a href="http://gcc.gnu.org/install/binaries.html">various
+websites</a> and are typically included as part of GNU/Linux
+distributions.  We expect that most people who build these binaries
+will include Go support.
+</p>
+
+<p>
+The GCC 4.7.1 release and all later 4.7 releases include a complete
+<a href="/doc/go1.html">Go 1</a> compiler and libraries.
+</p>
+
+<p>
+Due to timing, the GCC 4.8.0 and 4.8.1 releases are close to but not
+identical to Go 1.1.  The GCC 4.8.2 release includes a complete Go
+1.1.2 implementation.
+</p>
+
+<p>
+The GCC 4.9 releases include a complete Go 1.2 implementation.
+</p>
+
+<p>
+The GCC 5 releases include a complete implementation of the Go 1.4
+user libraries.  The Go 1.4 runtime is not fully merged, but that
+should not be visible to Go programs.
+</p>
+
+<p>
+The GCC 6 releases include a complete implementation of the Go 1.6.1
+user libraries.  The Go 1.6 runtime is not fully merged, but that
+should not be visible to Go programs.
+</p>
+
+<p>
+The GCC 7 releases are expected to include a complete implementation
+of the Go 1.8 user libraries.  As with earlier releases, the Go 1.8
+runtime is not fully merged, but that should not be visible to Go
+programs.
+</p>
+
+<h2 id="Source_code">Source code</h2>
+
+<p>
+If you cannot use a release, or prefer to build gccgo for
+yourself, 
+the gccgo source code is accessible via Subversion.  The
+GCC web site
+has <a href="http://gcc.gnu.org/svn.html">instructions for getting the
+GCC source code</a>.  The gccgo source code is included.  As a
+convenience, a stable version of the Go support is available in
+a branch of the main GCC code
+repository: <code>svn://gcc.gnu.org/svn/gcc/branches/gccgo</code>.
+This branch is periodically updated with stable Go compiler sources.
+</p>
+
+<p>
+Note that although <code>gcc.gnu.org</code> is the most convenient way
+to get the source code for the Go frontend, it is not where the master
+sources live.  If you want to contribute changes to the Go frontend
+compiler, see <a href="/doc/gccgo_contribute.html">Contributing to
+gccgo</a>.
+</p>
+
+
+<h2 id="Building">Building</h2>
+
+<p>
+Building gccgo is just like building GCC
+with one or two additional options.  See
+the <a href="http://gcc.gnu.org/install/">instructions on the gcc web
+site</a>.  When you run <code>configure</code>, add the
+option <code>--enable-languages=c,c++,go</code> (along with other
+languages you may want to build).  If you are targeting a 32-bit x86,
+then you will want to build gccgo to default to
+supporting locked compare and exchange instructions; do this by also
+using the <code>configure</code> option <code>--with-arch=i586</code>
+(or a newer architecture, depending on where you need your programs to
+run).  If you are targeting a 64-bit x86, but sometimes want to use
+the <code>-m32</code> option, then use the <code>configure</code>
+option <code>--with-arch-32=i586</code>.
+</p>
+
+<h3 id="Gold">Gold</h3>
+
+<p>
+On x86 GNU/Linux systems the gccgo compiler is able to
+use a small discontiguous stack for goroutines.  This permits programs
+to run many more goroutines, since each goroutine can use a relatively
+small stack.  Doing this requires using the gold linker version 2.22
+or later.  You can either install GNU binutils 2.22 or later, or you
+can build gold yourself.
+</p>
+
+<p>
+To build gold yourself, build the GNU binutils,
+using <code>--enable-gold=default</code> when you run
+the <code>configure</code> script.  Before building, you must install
+the flex and bison packages.  A typical sequence would look like
+this (you can replace <code>/opt/gold</code> with any directory to
+which you have write access):
+</p>
+
+<pre>
+cvs -z 9 -d :pserver:anoncvs@sourceware.org:/cvs/src login
+[password is "anoncvs"]
+[The next command will create a directory named src, not binutils]
+cvs -z 9 -d :pserver:anoncvs@sourceware.org:/cvs/src co binutils
+mkdir binutils-objdir
+cd binutils-objdir
+../src/configure --enable-gold=default --prefix=/opt/gold
+make
+make install
+</pre>
+
+<p>
+However you install gold, when you configure gccgo, use the
+option <code>--with-ld=<var>GOLD_BINARY</var></code>.
+</p>
+
+<h3 id="Prerequisites">Prerequisites</h3>
+
+<p>
+A number of prerequisites are required to build GCC, as
+described on
+the <a href="http://gcc.gnu.org/install/prerequisites.html">gcc web
+site</a>.  It is important to install all the prerequisites before
+running the gcc <code>configure</code> script.
+The prerequisite libraries can be conveniently downloaded using the
+script <code>contrib/download_prerequisites</code> in the GCC sources.
+
+<h3 id="Build_commands">Build commands</h3>
+
+<p>
+Once all the prerequisites are installed, then a typical build and
+install sequence would look like this (only use
+the <code>--with-ld</code> option if you are using the gold linker as
+described above):
+</p>
+
+<pre>
+svn checkout svn://gcc.gnu.org/svn/gcc/branches/gccgo gccgo
+mkdir objdir
+cd objdir
+../gccgo/configure --prefix=/opt/gccgo --enable-languages=c,c++,go --with-ld=/opt/gold/bin/ld
+make
+make install
+</pre>
+
+<h2 id="Using_gccgo">Using gccgo</h2>
+
+<p>
+The gccgo compiler works like other gcc frontends.  As of GCC 5 the gccgo
+installation also includes a version of the <code>go</code> command,
+which may be used to build Go programs as described at
+<a href="https://golang.org/cmd/go">https://golang.org/cmd/go</a>.
+</p>
+
+<p>
+To compile a file without using the <code>go</code> command:
+</p>
+
+<pre>
+gccgo -c file.go
+</pre>
+
+<p>
+That produces <code>file.o</code>. To link files together to form an
+executable:
+</p>
+
+<pre>
+gccgo -o file file.o
+</pre>
+
+<p>
+To run the resulting file, you will need to tell the program where to
+find the compiled Go packages.  There are a few ways to do this:
+</p>
+
+<ul>
+<li>
+<p>
+Set the <code>LD_LIBRARY_PATH</code> environment variable:
+</p>
+

+LD_LIBRARY_PATH=${prefix}/lib/gcc/MACHINE/VERSION
+[or]
+LD_LIBRARY_PATH=${prefix}/lib64/gcc/MACHINE/VERSION
+export LD_LIBRARY_PATH
+</pre>
+
+<p>
+Here <code>${prefix}</code> is the <code>--prefix</code> option used
+when building gccgo.  For a binary install this is
+normally <code>/usr</code>.  Whether to use <code>lib</code>
+or <code>lib64</code> depends on the target.
+Typically <code>lib64</code> is correct for x86_64 systems,
+and <code>lib</code> is correct for other systems.  The idea is to
+name the directory where <code>libgo.so</code> is found.
+</p>
+
+</li>
+
+<li>
+<p>
+Passing a <code>-Wl,-R</code> option when you link (replace lib with
+lib64 if appropriate for your system):
+</p>
+
+<pre>
+go build -gccgoflags -Wl,-R,${prefix}/lib/gcc/MACHINE/VERSION
+[or]
+gccgo -o file file.o -Wl,-R,${prefix}/lib/gcc/MACHINE/VERSION
+</pre>
+</li>
+
+<li>
+<p>
+Use the <code>-static-libgo</code> option to link statically against
+the compiled packages.
+</p>
+</li>
+
+<li>
+<p>
+Use the <code>-static</code> option to do a fully static link (the
+default for the <code>gc</code> compiler).
+</p>
+</li>
+</ul>
+
+<h2 id="Options">Options</h2>
+
+<p>
+The gccgo compiler supports all GCC options
+that are language independent, notably the <code>-O</code>
+and <code>-g</code> options.
+</p>
+
+<p>
+The <code>-fgo-pkgpath=PKGPATH</code> option may be used to set a
+unique prefix for the package being compiled.
+This option is automatically used by the go command, but you may want
+to use it if you invoke gccgo directly.
+This option is intended for use with large
+programs that contain many packages, in order to allow multiple
+packages to use the same identifier as the package name.
+The <code>PKGPATH</code> may be any string; a good choice for the
+string is the path used to import the package.
+</p>
+
+<p>
+The <code>-I</code> and <code>-L</code> options, which are synonyms
+for the compiler, may be used to set the search path for finding
+imports.
+These options are not needed if you build with the go command.
+</p>
+
+<h2 id="Imports">Imports</h2>
+
+<p>
+When you compile a file that exports something, the export
+information will be stored directly in the object file.
+If you build with gccgo directly, rather than with the go command,
+then when you import a package, you must tell gccgo how to find the
+file.
+</p>
+
+<p>
+When you import the package <var>FILE</var> with gccgo,
+it will look for the import data in the following files, and use the
+first one that it finds.
+
+<ul>
+<li><code><var>FILE</var>.gox</code>
+<li><code>lib<var>FILE</var>.so</code>
+<li><code>lib<var>FILE</var>.a</code>
+<li><code><var>FILE</var>.o</code>
+</ul>
+
+<p>
+<code><var>FILE</var>.gox</code>, when used, will typically contain
+nothing but export data. This can be generated from
+<code><var>FILE</var>.o</code> via
+</p>
+
+<pre>
+objcopy -j .go_export FILE.o FILE.gox
+</pre>
+
+<p>
+The gccgo compiler will look in the current
+directory for import files.  In more complex scenarios you
+may pass the <code>-I</code> or <code>-L</code> option to
+gccgo.  Both options take directories to search. The
+<code>-L</code> option is also passed to the linker.
+</p>
+
+<p>
+The gccgo compiler does not currently (2015-06-15) record
+the file name of imported packages in the object file. You must
+arrange for the imported data to be linked into the program.
+Again, this is not necessary when building with the go command.
+</p>
+
+<pre>
+gccgo -c mypackage.go              # Exports mypackage
+gccgo -c main.go                   # Imports mypackage
+gccgo -o main main.o mypackage.o   # Explicitly links with mypackage.o
+</pre>
+
+<h2 id="Debugging">Debugging</h2>
+
+<p>
+If you use the <code>-g</code> option when you compile, you can run
+<code>gdb</code> on your executable.  The debugger has only limited
+knowledge about Go.  You can set breakpoints, single-step,
+etc.  You can print variables, but they will be printed as though they
+had C/C++ types.  For numeric types this doesn't matter.  Go strings
+and interfaces will show up as two-element structures.  Go
+maps and channels are always represented as C pointers to run-time
+structures.
+</p>
+
+<h2 id="C_Interoperability">C Interoperability</h2>
+
+<p>
+When using gccgo there is limited interoperability with C,
+or with C++ code compiled using <code>extern "C"</code>.
+</p>
+
+<h3 id="Types">Types</h3>
+
+<p>
+Basic types map directly: an <code>int32</code> in Go is
+an <code>int32_t</code> in C, an <code>int64</code> is
+an <code>int64_t</code>, etc.
+The Go type <code>int</code> is an integer that is the same size as a
+pointer, and as such corresponds to the C type <code>intptr_t</code>.
+Go <code>byte</code> is equivalent to C <code>unsigned char</code>.
+Pointers in Go are pointers in C.
+A Go <code>struct</code> is the same as C <code>struct</code> with the
+same fields and types.
+</p>
+
+<p>
+The Go <code>string</code> type is currently defined as a two-element
+structure (this is <b style="color: red;">subject to change</b>):
+</p>
+
+<pre>
+struct __go_string {
+  const unsigned char *__data;
+  intptr_t __length;
+};
+</pre>
+
+<p>
+You can't pass arrays between C and Go. However, a pointer to an
+array in Go is equivalent to a C pointer to the
+equivalent of the element type.
+For example, Go <code>*[10]int</code> is equivalent to C <code>int*</code>,
+assuming that the C pointer does point to 10 elements.
+</p>
+
+<p>
+A slice in Go is a structure.  The current definition is
+(this is <b style="color: red;">subject to change</b>):
+</p>
+
+<pre>
+struct __go_slice {
+  void *__values;
+  intptr_t __count;
+  intptr_t __capacity;
+};
+</pre>
+
+<p>
+The type of a Go function is a pointer to a struct (this is
+<b style="color: red;">subject to change</b>).  The first field in the
+struct points to the code of the function, which will be equivalent to
+a pointer to a C function whose parameter types are equivalent, with
+an additional trailing parameter.  The trailing parameter is the
+closure, and the argument to pass is a pointer to the Go function
+struct.
+
+When a Go function returns more than one value, the C function returns
+a struct.  For example, these functions are roughly equivalent:
+</p>
+
+<pre>
+func GoFunction(int) (int, float64)
+struct { int i; float64 f; } CFunction(int, void*)
+</pre>
+
+<p>
+Go <code>interface</code>, <code>channel</code>, and <code>map</code>
+types have no corresponding C type (<code>interface</code> is a
+two-element struct and <code>channel</code> and <code>map</code> are
+pointers to structs in C, but the structs are deliberately undocumented). C
+<code>enum</code> types correspond to some integer type, but precisely
+which one is difficult to predict in general; use a cast. C <code>union</code>
+types have no corresponding Go type. C <code>struct</code> types containing
+bitfields have no corresponding Go type. C++ <code>class</code> types have
+no corresponding Go type.
+</p>
+
+<p>
+Memory allocation is completely different between C and Go, as Go uses
+garbage collection. The exact guidelines in this area are undetermined,
+but it is likely that it will be permitted to pass a pointer to allocated
+memory from C to Go. The responsibility of eventually freeing the pointer
+will remain with C side, and of course if the C side frees the pointer
+while the Go side still has a copy the program will fail. When passing a
+pointer from Go to C, the Go function must retain a visible copy of it in
+some Go variable. Otherwise the Go garbage collector may delete the
+pointer while the C function is still using it.
+</p>
+
+<h3 id="Function_names">Function names</h3>
+
+<p>
+Go code can call C functions directly using a Go extension implemented
+in gccgo: a function declaration may be preceded by
+<code>//extern NAME</code>.  For example, here is how the C function
+<code>open</code> can be declared in Go:
+</p>
+
+<pre>
+//extern open
+func c_open(name *byte, mode int, perm int) int
+</pre>
+
+<p>
+The C function naturally expects a NUL-terminated string, which in
+Go is equivalent to a pointer to an array (not a slice!) of
+<code>byte</code> with a terminating zero byte. So a sample call
+from Go would look like (after importing the <code>syscall</code> package):
+</p>
+
+<pre>
+var name = [4]byte{'f', 'o', 'o', 0};
+i := c_open(&amp;name[0], syscall.O_RDONLY, 0);
+</pre>
+
+<p>
+(this serves as an example only, to open a file in Go please use Go's
+<code>os.Open</code> function instead).
+</p>
+
+<p>
+Note that if the C function can block, such as in a call
+to <code>read</code>, calling the C function may block the Go program.
+Unless you have a clear understanding of what you are doing, all calls
+between C and Go should be implemented through cgo or SWIG, as for
+the <code>gc</code> compiler.
+</p>
+
+<p>
+The name of Go functions accessed from C is subject to change. At present
+the name of a Go function that does not have a receiver is
+<code>prefix.package.Functionname</code>. The prefix is set by
+the <code>-fgo-prefix</code> option used when the package is compiled;
+if the option is not used, the default is <code>go</code>.
+To call the function from C you must set the name using
+a GCC extension.
+</p>
+
+<pre>
+extern int go_function(int) __asm__ ("myprefix.mypackage.Function");
+</pre>
+
+<h3 id="Automatic_generation_of_Go_declarations_from_C_source_code">
+Automatic generation of Go declarations from C source code</h3>
+
+<p>
+The Go version of GCC supports automatically generating
+Go declarations from C code. The facility is rather awkward, and most
+users should use the <a href="/cmd/cgo">cgo</a> program with
+the <code>-gccgo</code> option instead.
+</p>
+
+<p>
+Compile your C code as usual, and add the option
+<code>-fdump-go-spec=<var>FILENAME</var></code>.  This will create the
+file <code><var>FILENAME</var></code> as a side effect of the
+compilation.  This file will contain Go declarations for the types,
+variables and functions declared in the C code.  C types that can not
+be represented in Go will be recorded as comments in the Go code.  The
+generated file will not have a <code>package</code> declaration, but
+can otherwise be compiled directly by gccgo.
+</p>
+
+<p>
+This procedure is full of unstated caveats and restrictions and we make no
+guarantee that it will not change in the future. It is more useful as a
+starting point for real Go code than as a regular procedure.

+	"Template": true
+}-->
+
+<h2 id="introduction">Introduction to Go 1.2</h2>
+
+<p>
+Since the release of <a href="/doc/go1.1.html">Go version 1.1</a> in April, 2013,
+the release schedule has been shortened to make the release process more efficient.
+This release, Go version 1.2 or Go 1.2 for short, arrives roughly six months after 1.1,
+while 1.1 took over a year to appear after 1.0.
+Because of the shorter time scale, 1.2 is a smaller delta than the step from 1.0 to 1.1,
+but it still has some significant developments, including
+a better scheduler and one new language feature.
+Of course, Go 1.2 keeps the <a href="/doc/go1compat.html">promise
+of compatibility</a>.
+The overwhelming majority of programs built with Go 1.1 (or 1.0 for that matter)
+will run without any changes whatsoever when moved to 1.2,
+although the introduction of one restriction
+to a corner of the language may expose already-incorrect code
+(see the discussion of the <a href="#use_of_nil">use of nil</a>).
+</p>
+
+<h2 id="language">Changes to the language</h2>
+
+<p>
+In the interest of firming up the specification, one corner case has been clarified,
+with consequences for programs.
+There is also one new language feature.
+</p>
+
+<h3 id="use_of_nil">Use of nil</h3>
+
+<p>
+The language now specifies that, for safety reasons,
+certain uses of nil pointers are guaranteed to trigger a run-time panic.
+For instance, in Go 1.0, given code like
+</p>
+
+<pre>
+type T struct {
+    X [1<<24]byte
+    Field int32
+}
+
+func main() {
+    var x *T
+    ...
+}
+</pre>
+
+<p>
+the <code>nil</code> pointer <code>x</code> could be used to access memory incorrectly:
+the expression <code>x.Field</code> could access memory at address <code>1<<24</code>.
+To prevent such unsafe behavior, in Go 1.2 the compilers now guarantee that any indirection through
+a nil pointer, such as illustrated here but also in nil pointers to arrays, nil interface values,
+nil slices, and so on, will either panic or return a correct, safe non-nil value.
+In short, any expression that explicitly or implicitly requires evaluation of a nil address is an error.
+The implementation may inject extra tests into the compiled program to enforce this behavior.
+</p>
+
+<p>
+Further details are in the
+<a href="//golang.org/s/go12nil">design document</a>.
+</p>
+
+<p>
+<em>Updating</em>:
+Most code that depended on the old behavior is erroneous and will fail when run.
+Such programs will need to be updated by hand.
+</p>
+
+<h3 id="three_index">Three-index slices</h3>
+
+<p>
+Go 1.2 adds the ability to specify the capacity as well as the length when using a slicing operation
+on an existing array or slice.
+A slicing operation creates a new slice by describing a contiguous section of an already-created array or slice:
+</p>
+
+<pre>
+var array [10]int
+slice := array[2:4]
+</pre>
+
+<p>
+The capacity of the slice is the maximum number of elements that the slice may hold, even after reslicing;
+it reflects the size of the underlying array.
+In this example, the capacity of the <code>slice</code> variable is 8.
+</p>
+
+<p>
+Go 1.2 adds new syntax to allow a slicing operation to specify the capacity as well as the length.
+A second
+colon introduces the capacity value, which must be less than or equal to the capacity of the
+source slice or array, adjusted for the origin. For instance,
+</p>
+
+<pre>
+slice = array[2:4:7]
+</pre>
+
+<p>
+sets the slice to have the same length as in the earlier example but its capacity is now only 5 elements (7-2).
+It is impossible to use this new slice value to access the last three elements of the original array.
+</p>
+
+<p>
+In this three-index notation, a missing first index (<code>[:i:j]</code>) defaults to zero but the other
+two indices must always be specified explicitly.
+It is possible that future releases of Go may introduce default values for these indices.
+</p>
+
+<p>
+Further details are in the
+<a href="//golang.org/s/go12slice">design document</a>.
+</p>
+
+<p>
+<em>Updating</em>:
+This is a backwards-compatible change that affects no existing programs.
+</p>
+
+<h2 id="impl">Changes to the implementations and tools</h2>
+
+<h3 id="preemption">Pre-emption in the scheduler</h3>
+
+<p>
+In prior releases, a goroutine that was looping forever could starve out other
+goroutines on the same thread, a serious problem when GOMAXPROCS
+provided only one user thread.
+In Go 1.2, this is partially addressed: The scheduler is invoked occasionally
+upon entry to a function.
+This means that any loop that includes a (non-inlined) function call can
+be pre-empted, allowing other goroutines to run on the same thread.
+</p>
+
+<h3 id="thread_limit">Limit on the number of threads</h3>
+
+<p>
+Go 1.2 introduces a configurable limit (default 10,000) to the total number of threads
+a single program may have in its address space, to avoid resource starvation
+issues in some environments.
+Note that goroutines are multiplexed onto threads so this limit does not directly
+limit the number of goroutines, only the number that may be simultaneously blocked
+in a system call.
+In practice, the limit is hard to reach.
+</p>
+
+<p>
+The new <a href="/pkg/runtime/debug/#SetMaxThreads"><code>SetMaxThreads</code></a> function in the
+<a href="/pkg/runtime/debug/"><code>runtime/debug</code></a> package controls the thread count limit.
+</p>
+
+<p>
+<em>Updating</em>:
+Few functions will be affected by the limit, but if a program dies because it hits the
+limit, it could be modified to call <code>SetMaxThreads</code> to set a higher count.
+Even better would be to refactor the program to need fewer threads, reducing consumption
+of kernel resources.
+</p>
+
+<h3 id="stack_size">Stack size</h3>
+
+<p>
+In Go 1.2, the minimum size of the stack when a goroutine is created has been lifted from 4KB to 8KB.
+Many programs were suffering performance problems with the old size, which had a tendency
+to introduce expensive stack-segment switching in performance-critical sections.
+The new number was determined by empirical testing.
+</p>
+
+<p>
+At the other end, the new function <a href="/pkg/runtime/debug/#SetMaxStack"><code>SetMaxStack</code></a>
+in the <a href="/pkg/runtime/debug"><code>runtime/debug</code></a> package controls
+the <em>maximum</em> size of a single goroutine's stack.
+The default is 1GB on 64-bit systems and 250MB on 32-bit systems.
+Before Go 1.2, it was too easy for a runaway recursion to consume all the memory on a machine.
+</p>
+
+<p>
+<em>Updating</em>:
+The increased minimum stack size may cause programs with many goroutines to use
+more memory. There is no workaround, but plans for future releases
+include new stack management technology that should address the problem better.
+</p>
+
+<h3 id="cgo_and_cpp">Cgo and C++</h3>
+
+<p>
+The <a href="/cmd/cgo/"><code>cgo</code></a> command will now invoke the C++
+compiler to build any pieces of the linked-to library that are written in C++;
+<a href="/cmd/cgo/">the documentation</a> has more detail.
+</p>
+
+<h3 id="go_tools_godoc">Godoc and vet moved to the go.tools subrepository</h3>
+
+<p>
+Both binaries are still included with the distribution, but the source code for the
+godoc and vet commands has moved to the
+<a href="//code.google.com/p/go.tools">go.tools</a> subrepository.
+</p>
+
+<p>
+Also, the core of the godoc program has been split into a
+<a href="https://code.google.com/p/go/source/browse/?repo=tools#hg%2Fgodoc">library</a>,
+while the command itself is in a separate
+<a href="https://code.google.com/p/go/source/browse/?repo=tools#hg%2Fcmd%2Fgodoc">directory</a>.
+The move allows the code to be updated easily and the separation into a library and command
+makes it easier to construct custom binaries for local sites and different deployment methods.
+</p>
+
+<p>
+<em>Updating</em>:
+Since godoc and vet are not part of the library,
+no client Go code depends on the their source and no updating is required.
+</p>
+
+<p>
+The binary distributions available from <a href="//golang.org">golang.org</a>
+include these binaries, so users of these distributions are unaffected.
+</p>
+
+<p>
+When building from source, users must use "go get" to install godoc and vet.
+(The binaries will continue to be installed in their usual locations, not
+<code>$GOPATH/bin</code>.)
+</p>
+
+<pre>
+$ go get code.google.com/p/go.tools/cmd/godoc
+$ go get code.google.com/p/go.tools/cmd/vet
+</pre>
+
+<h3 id="gccgo">Status of gccgo</h3>
+
+<p>
+We expect the future GCC 4.9 release to include gccgo with full
+support for Go 1.2.
+In the current (4.8.2) release of GCC, gccgo implements Go 1.1.2.
+</p>
+
+<h3 id="gc_changes">Changes to the gc compiler and linker</h3>
+
+<p>
+Go 1.2 has several semantic changes to the workings of the gc compiler suite.
+Most users will be unaffected by them.
+</p>
+
+<p>
+The <a href="/cmd/cgo/"><code>cgo</code></a> command now
+works when C++ is included in the library being linked against.
+See the <a href="/cmd/cgo/"><code>cgo</code></a> documentation
+for details.
+</p>
+
+<p>
+The gc compiler displayed a vestigial detail of its origins when
+a program had no <code>package</code> clause: it assumed
+the file was in package <code>main</code>.
+The past has been erased, and a missing <code>package</code> clause
+is now an error.
+</p>
+
+<p>
+On the ARM, the toolchain supports "external linking", which
+is a step towards being able to build shared libraries with the gc
+tool chain and to provide dynamic linking support for environments
+in which that is necessary.
+</p>
+
+<p>
+In the runtime for the ARM, with <code>5a</code>, it used to be possible to refer
+to the runtime-internal <code>m</code> (machine) and <code>g</code>
+(goroutine) variables using <code>R9</code> and <code>R10</code> directly.
+It is now necessary to refer to them by their proper names.
+</p>
+
+<p>
+Also on the ARM, the <code>5l</code> linker (sic) now defines the
+<code>MOVBS</code> and <code>MOVHS</code> instructions
+as synonyms of <code>MOVB</code> and <code>MOVH</code>,
+to make clearer the separation between signed and unsigned
+sub-word moves; the unsigned versions already existed with a
+<code>U</code> suffix.
+</p>
+
+<h3 id="cover">Test coverage</h3>
+
+<p>
+One major new feature of <a href="/pkg/go/"><code>go test</code></a> is
+that it can now compute and, with help from a new, separately installed
+"go tool cover" program, display test coverage results.
+</p>
+
+<p>
+The cover tool is part of the
+<a href="https://code.google.com/p/go/source/checkout?repo=tools"><code>go.tools</code></a>
+subrepository.
+It can be installed by running
+</p>
+
+<pre>
+$ go get code.google.com/p/go.tools/cmd/cover
+</pre>
+
+<p>
+The cover tool does two things.
+First, when "go test" is given the <code>-cover</code> flag, it is run automatically 
+to rewrite the source for the package and insert instrumentation statements.
+The test is then compiled and run as usual, and basic coverage statistics are reported:
+</p>
+
+<pre>
+$ go test -cover fmt
+ok  	fmt	0.060s	coverage: 91.4% of statements
+$
+</pre>
+
+<p>
+Second, for more detailed reports, different flags to "go test" can create a coverage profile file,
+which the cover program, invoked with "go tool cover", can then analyze.
+</p>
+
+<p>
+Details on how to generate and analyze coverage statistics can be found by running the commands
+</p>
+
+<pre>
+$ go help testflag
+$ go tool cover -help
+</pre>
+
+<h3 id="go_doc">The go doc command is deleted</h3>
+
+<p>
+The "go doc" command is deleted.
+Note that the <a href="/cmd/godoc/"><code>godoc</code></a> tool itself is not deleted,
+just the wrapping of it by the <a href="/cmd/go/"><code>go</code></a> command.
+All it did was show the documents for a package by package path,
+which godoc itself already does with more flexibility.
+It has therefore been deleted to reduce the number of documentation tools and,
+as part of the restructuring of godoc, encourage better options in future.
+</p>
+
+<p>
+<em>Updating</em>: For those who still need the precise functionality of running
+</p>
+
+<pre>
+$ go doc
+</pre>
+
+<p>
+in a directory, the behavior is identical to running
+</p>
+
+<pre>
+$ godoc .
+</pre>
+
+<h3 id="gocmd">Changes to the go command</h3>
+
+<p>
+The <a href="/cmd/go/"><code>go get</code></a> command
+now has a <code>-t</code> flag that causes it to download the dependencies
+of the tests run by the package, not just those of the package itself.
+By default, as before, dependencies of the tests are not downloaded.
+</p>
+
+<h2 id="performance">Performance</h2>
+
+<p>
+There are a number of significant performance improvements in the standard library; here are a few of them.
+</p>
+
+<ul> 
+
+<li>
+The <a href="/pkg/compress/bzip2/"><code>compress/bzip2</code></a>
+decompresses about 30% faster.
+</li>
+
+<li>
+The <a href="/pkg/crypto/des/"><code>crypto/des</code></a> package
+is about five times faster.
+</li>
+
+<li>
+The <a href="/pkg/encoding/json/"><code>encoding/json</code></a> package
+encodes about 30% faster.
+</li>
+
+<li>
+Networking performance on Windows and BSD systems is about 30% faster through the use
+of an integrated network poller in the runtime, similar to what was done for Linux and OS X
+in Go 1.1.
+</li>
+
+</ul>
+
+<h2 id="library">Changes to the standard library</h2>
+
+
+<h3 id="archive_tar_zip">The archive/tar and archive/zip packages</h3>
+
+<p>
+The
+<a href="/pkg/archive/tar/"><code>archive/tar</code></a>
+and
+<a href="/pkg/archive/zip/"><code>archive/zip</code></a>
+packages have had a change to their semantics that may break existing programs.
+The issue is that they both provided an implementation of the
+<a href="/pkg/os/#FileInfo"><code>os.FileInfo</code></a>
+interface that was not compliant with the specification for that interface.
+In particular, their <code>Name</code> method returned the full
+path name of the entry, but the interface specification requires that
+the method return only the base name (final path element).
+</p>
+
+<p>
+<em>Updating</em>: Since this behavior was newly implemented and
+a bit obscure, it is possible that no code depends on the broken behavior.
+If there are programs that do depend on it, they will need to be identified
+and fixed manually.
+</p>
+
+<h3 id="encoding">The new encoding package</h3>
+
+<p>
+There is a new package, <a href="/pkg/encoding/"><code>encoding</code></a>,
+that defines a set of standard encoding interfaces that may be used to
+build custom marshalers and unmarshalers for packages such as
+<a href="/pkg/encoding/xml/"><code>encoding/xml</code></a>,
+<a href="/pkg/encoding/json/"><code>encoding/json</code></a>,
+and
+<a href="/pkg/encoding/binary/"><code>encoding/binary</code></a>.
+These new interfaces have been used to tidy up some implementations in
+the standard library.
+</p>
+
+<p>
+The new interfaces are called
+<a href="/pkg/encoding/#BinaryMarshaler"><code>BinaryMarshaler</code></a>,
+<a href="/pkg/encoding/#BinaryUnmarshaler"><code>BinaryUnmarshaler</code></a>,
+<a href="/pkg/encoding/#TextMarshaler"><code>TextMarshaler</code></a>,
+and
+<a href="/pkg/encoding/#TextUnmarshaler"><code>TextUnmarshaler</code></a>.
+Full details are in the <a href="/pkg/encoding/">documentation</a> for the package
+and a separate <a href="//golang.org/s/go12encoding">design document</a>.
+</p>
+
+<h3 id="fmt_indexed_arguments">The fmt package</h3>
+
+<p>
+The <a href="/pkg/fmt/"><code>fmt</code></a> package's formatted print
+routines such as <a href="/pkg/fmt/#Printf"><code>Printf</code></a>
+now allow the data items to be printed to be accessed in arbitrary order
+by using an indexing operation in the formatting specifications.
+Wherever an argument is to be fetched from the argument list for formatting,
+either as the value to be formatted or as a width or specification integer,
+a new optional indexing notation <code>[</code><em>n</em><code>]</code>
+fetches argument <em>n</em> instead.
+The value of <em>n</em> is 1-indexed.
+After such an indexing operating, the next argument to be fetched by normal
+processing will be <em>n</em>+1.
+</p>
+
+<p>
+For example, the normal <code>Printf</code> call
+</p>
+
+<pre>
+fmt.Sprintf("%c %c %c\n", 'a', 'b', 'c')
+</pre>
+
+<p>
+would create the string <code>"a b c"</code>, but with indexing operations like this,
+</p>
+
+<pre>
+fmt.Sprintf("%[3]c %[1]c %c\n", 'a', 'b', 'c')
+</pre>
+
+<p>
+the result is "<code>"c a b"</code>. The <code>[3]</code> index accesses the third formatting
+argument, which is <code>'c'</code>, <code>[1]</code> accesses the first, <code>'a'</code>,
+and then the next fetch accesses the argument following that one, <code>'b'</code>.
+</p>
+
+<p>
+The motivation for this feature is programmable format statements to access
+the arguments in different order for localization, but it has other uses:
+</p>
+
+<pre>
+log.Printf("trace: value %v of type %[1]T\n", expensiveFunction(a.b[c]))
+</pre>
+
+<p>
+<em>Updating</em>: The change to the syntax of format specifications
+is strictly backwards compatible, so it affects no working programs.
+</p>
+
+<h3 id="text_template">The text/template and html/template packages</h3>
+
+<p>
+The
+<a href="/pkg/text/template/"><code>text/template</code></a> package
+has a couple of changes in Go 1.2, both of which are also mirrored in the
+<a href="/pkg/html/template/"><code>html/template</code></a> package.
+</p>
+
+<p>
+First, there are new default functions for comparing basic types.
+The functions are listed in this table, which shows their names and
+the associated familiar comparison operator.
+</p>
+
+<table cellpadding="0" summary="Template comparison functions">
+<tr>
+<th width="50"></th><th width="100">Name</th> <th width="50">Operator</th>
+</tr>
+<tr>
+<td></td><td><code>eq</code></td> <td><code>==</code></td>
+</tr>
+<tr>
+<td></td><td><code>ne</code></td> <td><code>!=</code></td>
+</tr>
+<tr>
+<td></td><td><code>lt</code></td> <td><code>&lt;</code></td>
+</tr>
+<tr>
+<td></td><td><code>le</code></td> <td><code>&lt;=</code></td>
+</tr>
+<tr>
+<td></td><td><code>gt</code></td> <td><code>&gt;</code></td>
+</tr>
+<tr>
+<td></td><td><code>ge</code></td> <td><code>&gt;=</code></td>
+</tr>
+</table>
+
+<p>
+These functions behave slightly differently from the corresponding Go operators.
+First, they operate only on basic types (<code>bool</code>, <code>int</code>,
+<code>float64</code>, <code>string</code>, etc.).
+(Go allows comparison of arrays and structs as well, under some circumstances.)
+Second, values can be compared as long as they are the same sort of value:
+any signed integer value can be compared to any other signed integer value for example. (Go
+does not permit comparing an <code>int8</code> and an <code>int16</code>).
+Finally, the <code>eq</code> function (only) allows comparison of the first
+argument with one or more following arguments. The template in this example,
+</p>
+
+<pre>
+{{"{{"}}if eq .A 1 2 3 {{"}}"}} equal {{"{{"}}else{{"}}"}} not equal {{"{{"}}end{{"}}"}}
+</pre>
+
+<p>
+reports "equal" if <code>.A</code> is equal to <em>any</em> of 1, 2, or 3.
+</p>
+
+<p>
+The second change is that a small addition to the grammar makes "if else if" chains easier to write.
+Instead of writing,
+</p>
+
+<pre>
+{{"{{"}}if eq .A 1{{"}}"}} X {{"{{"}}else{{"}}"}} {{"{{"}}if eq .A 2{{"}}"}} Y {{"{{"}}end{{"}}"}} {{"{{"}}end{{"}}"}} 
+</pre>
+
+<p>
+one can fold the second "if" into the "else" and have only one "end", like this:
+</p>
+
+<pre>
+{{"{{"}}if eq .A 1{{"}}"}} X {{"{{"}}else if eq .A 2{{"}}"}} Y {{"{{"}}end{{"}}"}}
+</pre>
+
+<p>
+The two forms are identical in effect; the difference is just in the syntax.
+</p>
+
+<p>
+<em>Updating</em>: Neither the "else if" change nor the comparison functions
+affect existing programs. Those that
+already define functions called <code>eq</code> and so on through a function
+map are unaffected because the associated function map will override the new
+default function definitions.
+</p>
+
+<h3 id="new_packages">New packages</h3>
+
+<p>
+There are two new packages.
+</p>
+
+<ul>
+<li>
+The <a href="/pkg/encoding/"><code>encoding</code></a> package is
+<a href="#encoding">described above</a>.
+</li>
+<li>
+The <a href="/pkg/image/color/palette/"><code>image/color/palette</code></a> package
+provides standard color palettes.
+</li>
+</ul>
+
+<h3 id="minor_library_changes">Minor changes to the library</h3>
+
+<p>
+The following list summarizes a number of minor changes to the library, mostly additions.
+See the relevant package documentation for more information about each change.
+</p>
+
+<ul>
+
+<li>
+The <a href="/pkg/archive/zip/"><code>archive/zip</code></a> package
+adds the
+<a href="/pkg/archive/zip/#File.DataOffset"><code>DataOffset</code></a> accessor
+to return the offset of a file's (possibly compressed) data within the archive.
+</li>
+
+<li>
+The <a href="/pkg/bufio/"><code>bufio</code></a> package
+adds <a href="/pkg/bufio/#Reader.Reset"><code>Reset</code></a>
+methods to <a href="/pkg/bufio/#Reader"><code>Reader</code></a> and
+<a href="/pkg/bufio/#Writer"><code>Writer</code></a>.
+These methods allow the <a href="/pkg/io/#Reader"><code>Readers</code></a>
+and <a href="/pkg/io/#Writer"><code>Writers</code></a>
+to be re-used on new input and output readers and writers, saving
+allocation overhead. 
+</li>
+
+<li>
+The <a href="/pkg/compress/bzip2/"><code>compress/bzip2</code></a>
+can now decompress concatenated archives.
+</li>
+
+<li>
+The <a href="/pkg/compress/flate/"><code>compress/flate</code></a>
+package adds a <a href="/pkg/compress/flate/#Writer.Reset"><code>Reset</code></a> 
+method on the <a href="/pkg/compress/flate/#Writer"><code>Writer</code></a>,
+to make it possible to reduce allocation when, for instance, constructing an
+archive to hold multiple compressed files.
+</li>
+
+<li>
+The <a href="/pkg/compress/gzip/"><code>compress/gzip</code></a> package's
+<a href="/pkg/compress/gzip/#Writer"><code>Writer</code></a> type adds a
+<a href="/pkg/compress/gzip/#Writer.Reset"><code>Reset</code></a>
+so it may be reused.
+</li>
+
+<li>
+The <a href="/pkg/compress/zlib/"><code>compress/zlib</code></a> package's
+<a href="/pkg/compress/zlib/#Writer"><code>Writer</code></a> type adds a
+<a href="/pkg/compress/zlib/#Writer.Reset"><code>Reset</code></a>
+so it may be reused.
+</li>
+
+<li>
+The <a href="/pkg/container/heap/"><code>container/heap</code></a> package
+adds a <a href="/pkg/container/heap/#Fix"><code>Fix</code></a>
+method to provide a more efficient way to update an item's position in the heap.
+</li>
+
+<li>
+The <a href="/pkg/container/list/"><code>container/list</code></a> package
+adds the <a href="/pkg/container/list/#List.MoveBefore"><code>MoveBefore</code></a>
+and
+<a href="/pkg/container/list/#List.MoveAfter"><code>MoveAfter</code></a>
+methods, which implement the obvious rearrangement.
+</li>
+
+<li>
+The <a href="/pkg/crypto/cipher/"><code>crypto/cipher</code></a> package
+adds the a new GCM mode (Galois Counter Mode), which is almost always
+used with AES encryption.
+</li>
+
+<li>
+The 
+<a href="/pkg/crypto/md5/"><code>crypto/md5</code></a> package
+adds a new <a href="/pkg/crypto/md5/#Sum"><code>Sum</code></a> function
+to simplify hashing without sacrificing performance.
+</li>
+
+<li>
+Similarly, the 
+<a href="/pkg/crypto/md5/"><code>crypto/sha1</code></a> package
+adds a new <a href="/pkg/crypto/sha1/#Sum"><code>Sum</code></a> function.
+</li>
+
+<li>
+Also, the
+<a href="/pkg/crypto/sha256/"><code>crypto/sha256</code></a> package
+adds <a href="/pkg/crypto/sha256/#Sum256"><code>Sum256</code></a>
+and <a href="/pkg/crypto/sha256/#Sum224"><code>Sum224</code></a> functions.
+</li>
+
+<li>
+Finally, the <a href="/pkg/crypto/sha512/"><code>crypto/sha512</code></a> package
+adds <a href="/pkg/crypto/sha512/#Sum512"><code>Sum512</code></a> and
+<a href="/pkg/crypto/sha512/#Sum384"><code>Sum384</code></a> functions.
+</li>
+
+<li>
+The <a href="/pkg/crypto/x509/"><code>crypto/x509</code></a> package
+adds support for reading and writing arbitrary extensions.
+</li>
+
+<li>
+The <a href="/pkg/crypto/tls/"><code>crypto/tls</code></a> package adds
+support for TLS 1.1, 1.2 and AES-GCM.
+</li>
+
+<li>
+The <a href="/pkg/database/sql/"><code>database/sql</code></a> package adds a
+<a href="/pkg/database/sql/#DB.SetMaxOpenConns"><code>SetMaxOpenConns</code></a>
+method on <a href="/pkg/database/sql/#DB"><code>DB</code></a> to limit the
+number of open connections to the database.
+</li>
+
+<li>
+The <a href="/pkg/encoding/csv/"><code>encoding/csv</code></a> package
+now always allows trailing commas on fields.
+</li>
+
+<li>
+The <a href="/pkg/encoding/gob/"><code>encoding/gob</code></a> package
+now treats channel and function fields of structures as if they were unexported,
+even if they are not. That is, it ignores them completely. Previously they would
+trigger an error, which could cause unexpected compatibility problems if an
+embedded structure added such a field.
+The package also now supports the generic <code>BinaryMarshaler</code> and
+<code>BinaryUnmarshaler</code> interfaces of the
+<a href="/pkg/encoding/"><code>encoding</code></a> package
+described above.
+</li>
+
+<li>
+The <a href="/pkg/encoding/json/"><code>encoding/json</code></a> package
+now will always escape ampersands as "\u0026" when printing strings.
+It will now accept but correct invalid UTF-8 in
+<a href="/pkg/encoding/json/#Marshal"><code>Marshal</code></a>
+(such input was previously rejected).
+Finally, it now supports the generic encoding interfaces of the
+<a href="/pkg/encoding/"><code>encoding</code></a> package
+described above.
+</li>
+
+<li>
+The <a href="/pkg/encoding/xml/"><code>encoding/xml</code></a> package
+now allows attributes stored in pointers to be marshaled.
+It also supports the generic encoding interfaces of the
+<a href="/pkg/encoding/"><code>encoding</code></a> package
+described above through the new
+<a href="/pkg/encoding/xml/#Marshaler"><code>Marshaler</code></a>,
+<a href="/pkg/encoding/xml/#Unmarshaler"><code>Unmarshaler</code></a>,
+and related
+<a href="/pkg/encoding/xml/#MarshalerAttr"><code>MarshalerAttr</code></a> and
+<a href="/pkg/encoding/xml/#UnmarshalerAttr"><code>UnmarshalerAttr</code></a>
+interfaces.
+The package also adds a
+<a href="/pkg/encoding/xml/#Encoder.Flush"><code>Flush</code></a> method
+to the
+<a href="/pkg/encoding/xml/#Encoder"><code>Encoder</code></a>
+type for use by custom encoders. See the documentation for
+<a href="/pkg/encoding/xml/#Encoder.EncodeToken"><code>EncodeToken</code></a>
+to see how to use it.
+</li>
+
+<li>
+The <a href="/pkg/flag/"><code>flag</code></a> package now
+has a <a href="/pkg/flag/#Getter"><code>Getter</code></a> interface
+to allow the value of a flag to be retrieved. Due to the
+Go 1 compatibility guidelines, this method cannot be added to the existing
+<a href="/pkg/flag/#Value"><code>Value</code></a>
+interface, but all the existing standard flag types implement it.
+The package also now exports the <a href="/pkg/flag/#CommandLine"><code>CommandLine</code></a>
+flag set, which holds the flags from the command line.
+</li>
+
+<li>
+The <a href="/pkg/go/ast/"><code>go/ast</code></a> package's
+<a href="/pkg/go/ast/#SliceExpr"><code>SliceExpr</code></a> struct
+has a new boolean field, <code>Slice3</code>, which is set to true
+when representing a slice expression with three indices (two colons).
+The default is false, representing the usual two-index form.
+</li>
+
+<li>
+The <a href="/pkg/go/build/"><code>go/build</code></a> package adds
+the <code>AllTags</code> field
+to the <a href="/pkg/go/build/#Package"><code>Package</code></a> type,
+to make it easier to process build tags.
+</li>
+
+<li>
+The <a href="/pkg/image/draw/"><code>image/draw</code></a> package now
+exports an interface, <a href="/pkg/image/draw/#Drawer"><code>Drawer</code></a>,
+that wraps the standard <a href="/pkg/image/draw/#Draw"><code>Draw</code></a> method.
+The Porter-Duff operators now implement this interface, in effect binding an operation to
+the draw operator rather than providing it explicitly.
+Given a paletted image as its destination, the new
+<a href="/pkg/image/draw/#FloydSteinberg"><code>FloydSteinberg</code></a>
+implementation of the
+<a href="/pkg/image/draw/#Drawer"><code>Drawer</code></a>
+interface will use the Floyd-Steinberg error diffusion algorithm to draw the image.
+To create palettes suitable for such processing, the new
+<a href="/pkg/image/draw/#Quantizer"><code>Quantizer</code></a> interface
+represents implementations of quantization algorithms that choose a palette
+given a full-color image.
+There are no implementations of this interface in the library.
+</li>
+
+<li>
+The <a href="/pkg/image/gif/"><code>image/gif</code></a> package
+can now create GIF files using the new
+<a href="/pkg/image/gif/#Encode"><code>Encode</code></a>
+and <a href="/pkg/image/gif/#EncodeAll"><code>EncodeAll</code></a>
+functions.
+Their options argument allows specification of an image
+<a href="/pkg/image/draw/#Quantizer"><code>Quantizer</code></a> to use;
+if it is <code>nil</code>, the generated GIF will use the 
+<a href="/pkg/image/color/palette/#Plan9"><code>Plan9</code></a>
+color map (palette) defined in the new
+<a href="/pkg/image/color/palette/"><code>image/color/palette</code></a> package.
+The options also specify a
+<a href="/pkg/image/draw/#Drawer"><code>Drawer</code></a>
+to use to create the output image;
+if it is <code>nil</code>, Floyd-Steinberg error diffusion is used.
+</li>
+
+<li>
+The <a href="/pkg/io/#Copy"><code>Copy</code></a> method of the
+<a href="/pkg/io/"><code>io</code></a> package now prioritizes its
+arguments differently.
+If one argument implements <a href="/pkg/io/#WriterTo"><code>WriterTo</code></a>
+and the other implements <a href="/pkg/io/#ReaderFrom"><code>ReaderFrom</code></a>,
+<a href="/pkg/io/#Copy"><code>Copy</code></a> will now invoke
+<a href="/pkg/io/#WriterTo"><code>WriterTo</code></a> to do the work,
+so that less intermediate buffering is required in general.
+</li>
+
+<li>
+The <a href="/pkg/net/"><code>net</code></a> package requires cgo by default
+because the host operating system must in general mediate network call setup.
+On some systems, though, it is possible to use the network without cgo, and useful
+to do so, for instance to avoid dynamic linking.
+The new build tag <code>netgo</code> (off by default) allows the construction of a
+<code>net</code> package in pure Go on those systems where it is possible.
+</li>
+
+<li>
+The <a href="/pkg/net/"><code>net</code></a> package adds a new field
+<code>DualStack</code> to the <a href="/pkg/net/#Dialer"><code>Dialer</code></a>
+struct for TCP connection setup using a dual IP stack as described in
+<a href="http://tools.ietf.org/html/rfc6555">RFC 6555</a>.
+</li>
+
+<li>
+The <a href="/pkg/net/http/"><code>net/http</code></a> package will no longer
+transmit cookies that are incorrect according to
+<a href="http://tools.ietf.org/html/rfc6265">RFC 6265</a>.
+It just logs an error and sends nothing.
+Also,
+the <a href="/pkg/net/http/"><code>net/http</code></a> package's
+<a href="/pkg/net/http/#ReadResponse"><code>ReadResponse</code></a>
+function now permits the <code>*Request</code> parameter to be <code>nil</code>,
+whereupon it assumes a GET request.
+Finally, an HTTP server will now serve HEAD
+requests transparently, without the need for special casing in handler code.
+While serving a HEAD request, writes to a 
+<a href="/pkg/net/http/#Handler"><code>Handler</code></a>'s
+<a href="/pkg/net/http/#ResponseWriter"><code>ResponseWriter</code></a>
+are absorbed by the
+<a href="/pkg/net/http/#Server"><code>Server</code></a>
+and the client receives an empty body as required by the HTTP specification.
+</li>
+
+<li>
+The <a href="/pkg/os/exec/"><code>os/exec</code></a> package's 
+<a href="/pkg/os/exec/#Cmd.StdinPipe"><code>Cmd.StdinPipe</code></a> method 
+returns an <code>io.WriteCloser</code>, but has changed its concrete
+implementation from <code>*os.File</code> to an unexported type that embeds
+<code>*os.File</code>, and it is now safe to close the returned value.
+Before Go 1.2, there was an unavoidable race that this change fixes.
+Code that needs access to the methods of <code>*os.File</code> can use an
+interface type assertion, such as <code>wc.(interface{ Sync() error })</code>.
+</li>
+
+<li>
+The <a href="/pkg/runtime/"><code>runtime</code></a> package relaxes
+the constraints on finalizer functions in
+<a href="/pkg/runtime/#SetFinalizer"><code>SetFinalizer</code></a>: the
+actual argument can now be any type that is assignable to the formal type of
+the function, as is the case for any normal function call in Go.
+</li>
+
+<li>
+The <a href="/pkg/sort/"><code>sort</code></a> package has a new
+<a href="/pkg/sort/#Stable"><code>Stable</code></a> function that implements
+stable sorting. It is less efficient than the normal sort algorithm, however.
+</li>
+
+<li>
+The <a href="/pkg/strings/"><code>strings</code></a> package adds
+an <a href="/pkg/strings/#IndexByte"><code>IndexByte</code></a>
+function for consistency with the <a href="/pkg/bytes/"><code>bytes</code></a> package.
+</li>
+
+<li>
+The <a href="/pkg/sync/atomic/"><code>sync/atomic</code></a> package
+adds a new set of swap functions that atomically exchange the argument with the
+value stored in the pointer, returning the old value.
+The functions are
+<a href="/pkg/sync/atomic/#SwapInt32"><code>SwapInt32</code></a>,
+<a href="/pkg/sync/atomic/#SwapInt64"><code>SwapInt64</code></a>,
+<a href="/pkg/sync/atomic/#SwapUint32"><code>SwapUint32</code></a>,
+<a href="/pkg/sync/atomic/#SwapUint64"><code>SwapUint64</code></a>,
+<a href="/pkg/sync/atomic/#SwapUintptr"><code>SwapUintptr</code></a>,
+and
+<a href="/pkg/sync/atomic/#SwapPointer"><code>SwapPointer</code></a>,
+which swaps an <code>unsafe.Pointer</code>.
+</li>
+
+<li>
+The <a href="/pkg/syscall/"><code>syscall</code></a> package now implements
+<a href="/pkg/syscall/#Sendfile"><code>Sendfile</code></a> for Darwin.
+</li>
+
+<li>
+The <a href="/pkg/testing/"><code>testing</code></a> package
+now exports the <a href="/pkg/testing/#TB"><code>TB</code></a> interface.
+It records the methods in common with the
+<a href="/pkg/testing/#T"><code>T</code></a>
+and
+<a href="/pkg/testing/#B"><code>B</code></a> types,
+to make it easier to share code between tests and benchmarks.
+Also, the
+<a href="/pkg/testing/#AllocsPerRun"><code>AllocsPerRun</code></a>
+function now quantizes the return value to an integer (although it
+still has type <code>float64</code>), to round off any error caused by
+initialization and make the result more repeatable. 
+</li>
+
+<li>
+The <a href="/pkg/text/template/"><code>text/template</code></a> package
+now automatically dereferences pointer values when evaluating the arguments
+to "escape" functions such as "html", to bring the behavior of such functions
+in agreement with that of other printing functions such as "printf".
+</li>
+
+<li>
+In the <a href="/pkg/time/"><code>time</code></a> package, the
+<a href="/pkg/time/#Parse"><code>Parse</code></a> function
+and
+<a href="/pkg/time/#Time.Format"><code>Format</code></a>
+method
+now handle time zone offsets with seconds, such as in the historical
+date "1871-01-01T05:33:02+00:34:08".
+Also, pattern matching in the formats for those routines is stricter: a non-lowercase letter
+must now follow the standard words such as "Jan" and "Mon".
+</li>
+
+<li>
+The <a href="/pkg/unicode/"><code>unicode</code></a> package
+adds <a href="/pkg/unicode/#In"><code>In</code></a>,
+a nicer-to-use but equivalent version of the original
+<a href="/pkg/unicode/#IsOneOf"><code>IsOneOf</code></a>,
+to see whether a character is a member of a Unicode category.
+</li>

+<h2 id="introduction">Introduction to Go 1.3</h2>
+
+<p>
+The latest Go release, version 1.3, arrives six months after 1.2,
+and contains no language changes.
+It focuses primarily on implementation work, providing 
+precise garbage collection,
+a major refactoring of the compiler tool chain that results in
+faster builds, especially for large projects,
+significant performance improvements across the board,
+and support for DragonFly BSD, Solaris, Plan 9 and Google's Native Client architecture (NaCl).
+It also has an important refinement to the memory model regarding synchronization.
+As always, Go 1.3 keeps the <a href="/doc/go1compat.html">promise
+of compatibility</a>,
+and almost everything 
+will continue to compile and run without change when moved to 1.3.
+</p>
+
+<h2 id="os">Changes to the supported operating systems and architectures</h2>
+
+<h3 id="win2000">Removal of support for Windows 2000</h3>
+
+<p>
+Microsoft stopped supporting Windows 2000 in 2010.
+Since it has <a href="https://codereview.appspot.com/74790043">implementation difficulties</a>
+regarding exception handling (signals in Unix terminology),
+as of Go 1.3 it is not supported by Go either.
+</p>
+
+<h3 id="dragonfly">Support for DragonFly BSD</h3>
+
+<p>
+Go 1.3 now includes experimental support for DragonFly BSD on the <code>amd64</code> (64-bit x86) and <code>386</code> (32-bit x86) architectures.
+It uses DragonFly BSD 3.6 or above.
+</p>
+
+<h3 id="freebsd">Support for FreeBSD</h3>
+
+<p>
+It was not announced at the time, but since the release of Go 1.2, support for Go on FreeBSD
+requires FreeBSD 8 or above.
+</p>
+
+<p>
+As of Go 1.3, support for Go on FreeBSD requires that the kernel be compiled with the
+<code>COMPAT_FREEBSD32</code> flag configured.
+</p>
+
+<p>
+In concert with the switch to EABI syscalls for ARM platforms, Go 1.3 will run only on FreeBSD 10.
+The x86 platforms, 386 and amd64, are unaffected.
+</p>
+
+<h3 id="nacl">Support for Native Client</h3>
+
+<p>
+Support for the Native Client virtual machine architecture has returned to Go with the 1.3 release.
+It runs on the 32-bit Intel architectures (<code>GOARCH=386</code>) and also on 64-bit Intel, but using
+32-bit pointers (<code>GOARCH=amd64p32</code>).
+There is not yet support for Native Client on ARM.
+Note that this is Native Client (NaCl), not Portable Native Client (PNaCl).
+Details about Native Client are <a href="https://developers.google.com/native-client/dev/">here</a>;
+how to set up the Go version is described <a href="//golang.org/wiki/NativeClient">here</a>.
+</p>
+
+<h3 id="netbsd">Support for NetBSD</h3>
+
+<p>
+As of Go 1.3, support for Go on NetBSD requires NetBSD 6.0 or above.
+</p>
+
+<h3 id="openbsd">Support for OpenBSD</h3>
+
+<p>
+As of Go 1.3, support for Go on OpenBSD requires OpenBSD 5.5 or above.
+</p>
+
+<h3 id="plan9">Support for Plan 9</h3>
+
+<p>
+Go 1.3 now includes experimental support for Plan 9 on the <code>386</code> (32-bit x86) architecture.
+It requires the <code>Tsemacquire</code> syscall, which has been in Plan 9 since June, 2012.
+</p>
+
+<h3 id="solaris">Support for Solaris</h3>
+
+<p>
+Go 1.3 now includes experimental support for Solaris on the <code>amd64</code> (64-bit x86) architecture.
+It requires illumos, Solaris 11 or above.
+</p>
+
+<h2 id="memory">Changes to the memory model</h2>
+
+<p>
+The Go 1.3 memory model <a href="https://codereview.appspot.com/75130045">adds a new rule</a>
+concerning sending and receiving on buffered channels,
+to make explicit that a buffered channel can be used as a simple
+semaphore, using a send into the
+channel to acquire and a receive from the channel to release.
+This is not a language change, just a clarification about an expected property of communication.
+</p>
+
+<h2 id="impl">Changes to the implementations and tools</h2>
+
+<h3 id="stacks">Stack</h3>
+
+<p>
+Go 1.3 has changed the implementation of goroutine stacks away from the old,
+"segmented" model to a contiguous model.
+When a goroutine needs more stack
+than is available, its stack is transferred to a larger single block of memory.
+The overhead of this transfer operation amortizes well and eliminates the old "hot spot"
+problem when a calculation repeatedly steps across a segment boundary.
+Details including performance numbers are in this
+<a href="//golang.org/s/contigstacks">design document</a>.
+</p>
+
+<h3 id="garbage_collector">Changes to the garbage collector</h3>
+
+<p>
+For a while now, the garbage collector has been <em>precise</em> when examining
+values in the heap; the Go 1.3 release adds equivalent precision to values on the stack.
+This means that a non-pointer Go value such as an integer will never be mistaken for a
+pointer and prevent unused memory from being reclaimed.
+</p>
+
+<p>
+Starting with Go 1.3, the runtime assumes that values with pointer type
+contain pointers and other values do not.
+This assumption is fundamental to the precise behavior of both stack expansion
+and garbage collection.
+Programs that use <a href="/pkg/unsafe/">package unsafe</a>
+to store integers in pointer-typed values are illegal and will crash if the runtime detects the behavior.
+Programs that use <a href="/pkg/unsafe/">package unsafe</a> to store pointers
+in integer-typed values are also illegal but more difficult to diagnose during execution.
+Because the pointers are hidden from the runtime, a stack expansion or garbage collection
+may reclaim the memory they point at, creating
+<a href="//en.wikipedia.org/wiki/Dangling_pointer">dangling pointers</a>.
+</p>
+
+<p>
+<em>Updating</em>: Code that uses <code>unsafe.Pointer</code> to convert
+an integer-typed value held in memory into a pointer is illegal and must be rewritten.
+Such code can be identified by <code>go vet</code>.
+</p>
+
+<h3 id="map">Map iteration</h3>
+
+<p>
+Iterations over small maps no longer happen in a consistent order.
+Go 1 defines that &ldquo;<a href="//golang.org/ref/spec#For_statements">The iteration order over maps
+is not specified and is not guaranteed to be the same from one iteration to the next.</a>&rdquo;
+To keep code from depending on map iteration order,
+Go 1.0 started each map iteration at a random index in the map.
+A new map implementation introduced in Go 1.1 neglected to randomize
+iteration for maps with eight or fewer entries, although the iteration order
+can still vary from system to system.
+This has allowed people to write Go 1.1 and Go 1.2 programs that
+depend on small map iteration order and therefore only work reliably on certain systems.
+Go 1.3 reintroduces random iteration for small maps in order to flush out these bugs.
+</p>
+
+<p>
+<em>Updating</em>: If code assumes a fixed iteration order for small maps,
+it will break and must be rewritten not to make that assumption.
+Because only small maps are affected, the problem arises most often in tests.
+</p>
+
+<h3 id="liblink">The linker</h3>
+
+<p>
+As part of the general <a href="//golang.org/s/go13linker">overhaul</a> to
+the Go linker, the compilers and linkers have been refactored.
+The linker is still a C program, but now the instruction selection phase that
+was part of the linker has been moved to the compiler through the creation of a new
+library called <code>liblink</code>.
+By doing instruction selection only once, when the package is first compiled,
+this can speed up compilation of large projects significantly.
+</p>
+
+<p>
+<em>Updating</em>: Although this is a major internal change, it should have no
+effect on programs.
+</p>
+
+<h3 id="gccgo">Status of gccgo</h3>
+
+<p>
+GCC release 4.9 will contain the Go 1.2 (not 1.3) version of gccgo.
+The release schedules for the GCC and Go projects do not coincide,
+which means that 1.3 will be available in the development branch but
+that the next GCC release, 4.10, will likely have the Go 1.4 version of gccgo.
+</p>
+
+<h3 id="gocmd">Changes to the go command</h3>
+
+<p>
+The <a href="/cmd/go/"><code>cmd/go</code></a> command has several new
+features.
+The <a href="/cmd/go/"><code>go run</code></a> and
+<a href="/cmd/go/"><code>go test</code></a> subcommands
+support a new <code>-exec</code> option to specify an alternate
+way to run the resulting binary.
+Its immediate purpose is to support NaCl.
+</p>
+
+<p>
+The test coverage support of the <a href="/cmd/go/"><code>go test</code></a>
+subcommand now automatically sets the coverage mode to <code>-atomic</code>
+when the race detector is enabled, to eliminate false reports about unsafe
+access to coverage counters.
+</p>
+
+<p>
+The <a href="/cmd/go/"><code>go test</code></a> subcommand
+now always builds the package, even if it has no test files.
+Previously, it would do nothing if no test files were present.
+</p>
+
+<p>
+The <a href="/cmd/go/"><code>go build</code></a> subcommand
+supports a new <code>-i</code> option to install dependencies
+of the specified target, but not the target itself.
+</p>
+
+<p>
+Cross compiling with <a href="/cmd/cgo/"><code>cgo</code></a> enabled
+is now supported.
+The CC_FOR_TARGET and CXX_FOR_TARGET environment
+variables are used when running all.bash to specify the cross compilers
+for C and C++ code, respectively.
+</p>
+
+<p>
+Finally, the go command now supports packages that import Objective-C
+files (suffixed <code>.m</code>) through cgo.
+</p>
+
+<h3 id="cgo">Changes to cgo</h3>
+
+<p>
+The <a href="/cmd/cgo/"><code>cmd/cgo</code></a> command,
+which processes <code>import "C"</code> declarations in Go packages,
+has corrected a serious bug that may cause some packages to stop compiling.
+Previously, all pointers to incomplete struct types translated to the Go type <code>*[0]byte</code>,
+with the effect that the Go compiler could not diagnose passing one kind of struct pointer
+to a function expecting another.
+Go 1.3 corrects this mistake by translating each different
+incomplete struct to a different named type.
+</p>
+
+<p>
+Given the C declaration <code>typedef struct S T</code> for an incomplete <code>struct S</code>,
+some Go code used this bug to refer to the types <code>C.struct_S</code> and <code>C.T</code> interchangeably.
+Cgo now explicitly allows this use, even for completed struct types.
+However, some Go code also used this bug to pass (for example) a <code>*C.FILE</code>
+from one package to another.
+This is not legal and no longer works: in general Go packages
+should avoid exposing C types and names in their APIs.
+</p>
+
+<p>
+<em>Updating</em>: Code confusing pointers to incomplete types or
+passing them across package boundaries will no longer compile
+and must be rewritten.
+If the conversion is correct and must be preserved,
+use an explicit conversion via <a href="/pkg/unsafe/#Pointer"><code>unsafe.Pointer</code></a>.
+</p>
+
+<h3 id="swig">SWIG 3.0 required for programs that use SWIG</h3>
+
+<p>
+For Go programs that use SWIG, SWIG version 3.0 is now required.
+The <a href="/cmd/go"><code>cmd/go</code></a> command will now link the
+SWIG generated object files directly into the binary, rather than
+building and linking with a shared library.
+</p>
+
+<h3 id="gc_flag">Command-line flag parsing</h3>
+
+<p>
+In the gc tool chain, the assemblers now use the
+same command-line flag parsing rules as the Go flag package, a departure
+from the traditional Unix flag parsing.
+This may affect scripts that invoke the tool directly.
+For example,
+<code>go tool 6a -SDfoo</code> must now be written
+<code>go tool 6a -S -D foo</code>.
+(The same change was made to the compilers and linkers in <a href="/doc/go1.1#gc_flag">Go 1.1</a>.)
+</p>
+
+<h3 id="godoc">Changes to godoc</h3>
+<p>
+When invoked with the <code>-analysis</code> flag, 
+<a href="//godoc.org/golang.org/x/tools/cmd/godoc">godoc</a>
+now performs sophisticated <a href="/lib/godoc/analysis/help.html">static
+analysis</a> of the code it indexes.  
+The results of analysis are presented in both the source view and the
+package documentation view, and include the call graph of each package
+and the relationships between 
+definitions and references,
+types and their methods,
+interfaces and their implementations,
+send and receive operations on channels,
+functions and their callers, and
+call sites and their callees.
+</p>
+
+<h3 id="misc">Miscellany</h3>
+
+<p>
+The program <code>misc/benchcmp</code> that compares
+performance across benchmarking runs has been rewritten.
+Once a shell and awk script in the main repository, it is now a Go program in the <code>go.tools</code> repo.
+Documentation is <a href="//godoc.org/golang.org/x/tools/cmd/benchcmp">here</a>.
+</p>
+
+<p>
+For the few of us that build Go distributions, the tool <code>misc/dist</code> has been
+moved and renamed; it now lives in <code>misc/makerelease</code>, still in the main repository.
+</p>
+
+<h2 id="performance">Performance</h2>
+
+<p>
+The performance of Go binaries for this release has improved in many cases due to changes
+in the runtime and garbage collection, plus some changes to libraries.
+Significant instances include:
+</p>
+
+<ul> 
+
+<li>
+The runtime handles defers more efficiently, reducing the memory footprint by about two kilobytes
+per goroutine that calls defer.
+</li>
+
+<li>
+The garbage collector has been sped up, using a concurrent sweep algorithm,
+better parallelization, and larger pages.
+The cumulative effect can be a 50-70% reduction in collector pause time.
+</li>
+
+<li>
+The race detector (see <a href="/doc/articles/race_detector.html">this guide</a>)
+is now about 40% faster.
+</li>
+
+<li>
+The regular expression package <a href="/pkg/regexp/"><code>regexp</code></a>
+is now significantly faster for certain simple expressions due to the implementation of
+a second, one-pass execution engine.
+The choice of which engine to use is automatic;
+the details are hidden from the user.
+</li>
+
+</ul>
+
+<p>
+Also, the runtime now includes in stack dumps how long a goroutine has been blocked,
+which can be useful information when debugging deadlocks or performance issues.
+</p>
+
+<h2 id="library">Changes to the standard library</h2>
+
+<h3 id="new_packages">New packages</h3>
+
+<p>
+A new package <a href="/pkg/debug/plan9obj/"><code>debug/plan9obj</code></a> was added to the standard library.
+It implements access to Plan 9 <a href="http://plan9.bell-labs.com/magic/man2html/6/a.out">a.out</a> object files.
+</p>
+
+<h3 id="major_library_changes">Major changes to the library</h3>
+
+<p>
+A previous bug in <a href="/pkg/crypto/tls/"><code>crypto/tls</code></a>
+made it possible to skip verification in TLS inadvertently.
+In Go 1.3, the bug is fixed: one must specify either ServerName or
+InsecureSkipVerify, and if ServerName is specified it is enforced.
+This may break existing code that incorrectly depended on insecure
+behavior.
+</p>
+
+<p>
+There is an important new type added to the standard library: <a href="/pkg/sync/#Pool"><code>sync.Pool</code></a>.
+It provides an efficient mechanism for implementing certain types of caches whose memory
+can be reclaimed automatically by the system.
+</p>
+
+<p>
+The <a href="/pkg/testing/"><code>testing</code></a> package's benchmarking helper,
+<a href="/pkg/testing/#B"><code>B</code></a>, now has a
+<a href="/pkg/testing/#B.RunParallel"><code>RunParallel</code></a> method
+to make it easier to run benchmarks that exercise multiple CPUs.
+</p>
+
+<p>
+<em>Updating</em>: The crypto/tls fix may break existing code, but such
+code was erroneous and should be updated.
+</p>
+
+<h3 id="minor_library_changes">Minor changes to the library</h3>
+
+<p>
+The following list summarizes a number of minor changes to the library, mostly additions.
+See the relevant package documentation for more information about each change.
+</p>
+
+<ul>
+
+<li> In the <a href="/pkg/crypto/tls/"><code>crypto/tls</code></a> package,
+a new <a href="/pkg/crypto/tls/#DialWithDialer"><code>DialWithDialer</code></a>
+function lets one establish a TLS connection using an existing dialer, making it easier
+to control dial options such as timeouts.
+The package also now reports the TLS version used by the connection in the
+<a href="/pkg/crypto/tls/#ConnectionState"><code>ConnectionState</code></a>
+struct.
+</li>
+
+<li> The <a href="/pkg/crypto/x509/#CreateCertificate"><code>CreateCertificate</code></a>
+function of the <a href="/pkg/crypto/tls/"><code>crypto/tls</code></a> package
+now supports parsing (and elsewhere, serialization) of PKCS #10 certificate
+signature requests.
+</li>
+
+<li>
+The formatted print functions of the <code>fmt</code> package now define <code>%F</code>
+as a synonym for <code>%f</code> when printing floating-point values.
+</li>
+
+<li>
+The <a href="/pkg/math/big/"><code>math/big</code></a> package's
+<a href="/pkg/math/big/#Int"><code>Int</code></a> and
+<a href="/pkg/math/big/#Rat"><code>Rat</code></a> types
+now implement
+<a href="/pkg/encoding/#TextMarshaler"><code>encoding.TextMarshaler</code></a> and
+<a href="/pkg/encoding/#TextUnmarshaler"><code>encoding.TextUnmarshaler</code></a>.
+</li>
+
+<li>
+The complex power function, <a href="/pkg/math/cmplx/#Pow"><code>Pow</code></a>,
+now specifies the behavior when the first argument is zero.
+It was undefined before.
+The details are in the <a href="/pkg/math/cmplx/#Pow">documentation for the function</a>.
+</li>
+
+<li>
+The <a href="/pkg/net/http/"><code>net/http</code></a> package now exposes the
+properties of a TLS connection used to make a client request in the new
+<a href="/pkg/net/http/#Response"><code>Response.TLS</code></a> field.
+</li>
+
+<li>
+The <a href="/pkg/net/http/"><code>net/http</code></a> package now
+allows setting an optional server error logger
+with <a href="/pkg/net/http/#Server"><code>Server.ErrorLog</code></a>.
+The default is still that all errors go to stderr.
+</li>
+
+<li>
+The <a href="/pkg/net/http/"><code>net/http</code></a> package now
+supports disabling HTTP keep-alive connections on the server
+with <a href="/pkg/net/http/#Server.SetKeepAlivesEnabled"><code>Server.SetKeepAlivesEnabled</code></a>.
+The default continues to be that the server does keep-alive (reuses
+connections for multiple requests) by default.
+Only resource-constrained servers or those in the process of graceful
+shutdown will want to disable them.
+</li>
+
+<li>
+The <a href="/pkg/net/http/"><code>net/http</code></a> package adds an optional
+<a href="/pkg/net/http/#Transport"><code>Transport.TLSHandshakeTimeout</code></a>
+setting to cap the amount of time HTTP client requests will wait for
+TLS handshakes to complete.
+It's now also set by default
+on <a href="/pkg/net/http#DefaultTransport"><code>DefaultTransport</code></a>.
+</li>
+
+<li>
+The <a href="/pkg/net/http/"><code>net/http</code></a> package's
+<a href="/pkg/net/http/#DefaultTransport"><code>DefaultTransport</code></a>,
+used by the HTTP client code, now
+enables <a href="http://en.wikipedia.org/wiki/Keepalive#TCP_keepalive">TCP
+keep-alives</a> by default.
+Other <a href="/pkg/net/http/#Transport"><code>Transport</code></a>
+values with a nil <code>Dial</code> field continue to function the same
+as before: no TCP keep-alives are used.
+</li>
+
+<li>
+The <a href="/pkg/net/http/"><code>net/http</code></a> package
+now enables <a href="http://en.wikipedia.org/wiki/Keepalive#TCP_keepalive">TCP
+keep-alives</a> for incoming server requests when
+<a href="/pkg/net/http/#ListenAndServe"><code>ListenAndServe</code></a>
+or
+<a href="/pkg/net/http/#ListenAndServeTLS"><code>ListenAndServeTLS</code></a>
+are used.
+When a server is started otherwise, TCP keep-alives are not enabled.
+</li>
+
+<li>
+The <a href="/pkg/net/http/"><code>net/http</code></a> package now
+provides an
+optional <a href="/pkg/net/http/#Server"><code>Server.ConnState</code></a>
+callback to hook various phases of a server connection's lifecycle
+(see <a href="/pkg/net/http/#ConnState"><code>ConnState</code></a>).
+This can be used to implement rate limiting or graceful shutdown.
+</li>
+
+<li>
+The <a href="/pkg/net/http/"><code>net/http</code></a> package's HTTP
+client now has an
+optional <a href="/pkg/net/http/#Client"><code>Client.Timeout</code></a>
+field to specify an end-to-end timeout on requests made using the
+client.
+</li>
+
+<li>
+The <a href="/pkg/net/http/"><code>net/http</code></a> package's
+<a href="/pkg/net/http/#Request.ParseMultipartForm"><code>Request.ParseMultipartForm</code></a>
+method will now return an error if the body's <code>Content-Type</code>
+is not <code>mutipart/form-data</code>.
+Prior to Go 1.3 it would silently fail and return <code>nil</code>.
+Code that relies on the previous behavior should be updated.
+</li>
+
+<li> In the <a href="/pkg/net/"><code>net</code></a> package,
+the <a href="/pkg/net/#Dialer"><code>Dialer</code></a> struct now
+has a <code>KeepAlive</code> option to specify a keep-alive period for the connection.
+</li>
+
+<li>
+The <a href="/pkg/net/http/"><code>net/http</code></a> package's 
+<a href="/pkg/net/http/#Transport"><code>Transport</code></a>
+now closes <a href="/pkg/net/http/#Request"><code>Request.Body</code></a>
+consistently, even on error.
+</li>
+
+<li>
+The <a href="/pkg/os/exec/"><code>os/exec</code></a> package now implements
+what the documentation has always said with regard to relative paths for the binary.
+In particular, it only calls <a href="/pkg/os/exec/#LookPath"><code>LookPath</code></a>
+when the binary's file name contains no path separators.
+</li>
+
+<li>
+The <a href="/pkg/reflect/#Value.SetMapIndex"><code>SetMapIndex</code></a>
+function in the <a href="/pkg/reflect/"><code>reflect</code></a> package
+no longer panics when deleting from a <code>nil</code> map.
+</li>
+
+<li>
+If the main goroutine calls 
+<a href="/pkg/runtime/#Goexit"><code>runtime.Goexit</code></a>
+and all other goroutines finish execution, the program now always crashes,
+reporting a detected deadlock.
+Earlier versions of Go handled this situation inconsistently: most instances
+were reported as deadlocks, but some trivial cases exited cleanly instead.
+</li>
+
+<li>
+The runtime/debug package now has a new function
+<a href="/pkg/runtime/debug/#WriteHeapDump"><code>debug.WriteHeapDump</code></a>
+that writes out a description of the heap.
+</li>
+
+<li>
+The <a href="/pkg/strconv/#CanBackquote"><code>CanBackquote</code></a>
+function in the <a href="/pkg/strconv/"><code>strconv</code></a> package
+now considers the <code>DEL</code> character, <code>U+007F</code>, to be
+non-printing.
+</li>
+
+<li>
+The <a href="/pkg/syscall/"><code>syscall</code></a> package now provides
+<a href="/pkg/syscall/#SendmsgN"><code>SendmsgN</code></a>
+as an alternate version of
+<a href="/pkg/syscall/#Sendmsg"><code>Sendmsg</code></a>
+that returns the number of bytes written.
+</li>
+
+<li>
+On Windows, the <a href="/pkg/syscall/"><code>syscall</code></a> package now
+supports the cdecl calling convention through the addition of a new function
+<a href="/pkg/syscall/#NewCallbackCDecl"><code>NewCallbackCDecl</code></a>
+alongside the existing function
+<a href="/pkg/syscall/#NewCallback"><code>NewCallback</code></a>.
+</li>
+
+<li>
+The <a href="/pkg/testing/"><code>testing</code></a> package now
+diagnoses tests that call <code>panic(nil)</code>, which are almost always erroneous.
+Also, tests now write profiles (if invoked with profiling flags) even on failure.
+</li>
+
+<li>
+The <a href="/pkg/unicode/"><code>unicode</code></a> package and associated

+<h2 id="introduction">Introduction to Go 1.4</h2>
+
+<p>
+The latest Go release, version 1.4, arrives as scheduled six months after 1.3.
+</p>
+
+<p>
+It contains only one tiny language change,
+in the form of a backwards-compatible simple variant of <code>for</code>-<code>range</code> loop,
+and a possibly breaking change to the compiler involving methods on pointers-to-pointers.
+</p>
+
+<p>
+The release focuses primarily on implementation work, improving the garbage collector
+and preparing the ground for a fully concurrent collector to be rolled out in the
+next few releases.
+Stacks are now contiguous, reallocated when necessary rather than linking on new
+"segments";
+this release therefore eliminates the notorious "hot stack split" problem.
+There are some new tools available including support in the <code>go</code> command
+for build-time source code generation.
+The release also adds support for ARM processors on Android and Native Client (NaCl)
+and for AMD64 on Plan 9.
+</p>
+
+<p>
+As always, Go 1.4 keeps the <a href="/doc/go1compat.html">promise
+of compatibility</a>,
+and almost everything 
+will continue to compile and run without change when moved to 1.4.
+</p>
+
+<h2 id="language">Changes to the language</h2>
+
+<h3 id="forrange">For-range loops</h3>
+<p>
+Up until Go 1.3, <code>for</code>-<code>range</code> loop had two forms
+</p>
+
+<pre>
+for i, v := range x {
+	...
+}
+</pre>
+
+<p>
+and
+</p>
+
+<pre>
+for i := range x {
+	...
+}
+</pre>
+
+<p>
+If one was not interested in the loop values, only the iteration itself, it was still
+necessary to mention a variable (probably the <a href="/ref/spec#Blank_identifier">blank identifier</a>, as in
+<code>for</code> <code>_</code> <code>=</code> <code>range</code> <code>x</code>), because
+the form
+</p>
+
+<pre>
+for range x {
+	...
+}
+</pre>
+
+<p>
+was not syntactically permitted.
+</p>
+
+<p>
+This situation seemed awkward, so as of Go 1.4 the variable-free form is now legal.
+The pattern arises rarely but the code can be cleaner when it does.
+</p>
+
+<p>
+<em>Updating</em>: The change is strictly backwards compatible to existing Go
+programs, but tools that analyze Go parse trees may need to be modified to accept
+this new form as the
+<code>Key</code> field of <a href="/pkg/go/ast/#RangeStmt"><code>RangeStmt</code></a>
+may now be <code>nil</code>.
+</p>
+
+<h3 id="methodonpointertopointer">Method calls on **T</h3>
+
+<p>
+Given these declarations,
+</p>
+
+<pre>
+type T int
+func (T) M() {}
+var x **T
+</pre>
+
+<p>
+both <code>gc</code> and <code>gccgo</code> accepted the method call
+</p>
+
+<pre>
+x.M()
+</pre>
+
+<p>
+which is a double dereference of the pointer-to-pointer <code>x</code>.
+The Go specification allows a single dereference to be inserted automatically,
+but not two, so this call is erroneous according to the language definition.
+It has therefore been disallowed in Go 1.4, which is a breaking change,
+although very few programs will be affected.
+</p>
+
+<p>
+<em>Updating</em>: Code that depends on the old, erroneous behavior will no longer
+compile but is easy to fix by adding an explicit dereference.

+</p>
+
+<h2 id="compatibility">Changes to the compatibility guidelines</h2>
+
+<p>
+The <a href="/pkg/unsafe/"><code>unsafe</code></a> package allows one
+to defeat Go's type system by exploiting internal details of the implementation
+or machine representation of data.
+It was never explicitly specified what use of <code>unsafe</code> meant
+with respect to compatibility as specified in the
+<a href="go1compat.html">Go compatibility guidelines</a>.
+The answer, of course, is that we can make no promise of compatibility
+for code that does unsafe things.
+</p>
+
+<p>
+We have clarified this situation in the documentation included in the release.
+The <a href="go1compat.html">Go compatibility guidelines</a> and the
+docs for the <a href="/pkg/unsafe/"><code>unsafe</code></a> package
+are now explicit that unsafe code is not guaranteed to remain compatible.
+</p>
+  
+<p>
+<em>Updating</em>: Nothing technical has changed; this is just a clarification
+of the documentation.
+</p>
+
+
+<h2 id="impl">Changes to the implementations and tools</h2>
+
+<h3 id="runtime">Changes to the runtime</h3>
+
+<p>
+Prior to Go 1.4, the runtime (garbage collector, concurrency support, interface management,
+maps, slices, strings, ...) was mostly written in C, with some assembler support.
+In 1.4, much of the code has been translated to Go so that the garbage collector can scan
+the stacks of programs in the runtime and get accurate information about what variables
+are active.
+This change was large but should have no semantic effect on programs.
+</p>
+
+<p>
+This rewrite allows the garbage collector in 1.4 to be fully precise,
+meaning that it is aware of the location of all active pointers in the program.
+This means the heap will be smaller as there will be no false positives keeping non-pointers alive.
+Other related changes also reduce the heap size, which is smaller by 10%-30% overall
+relative to the previous release.
+</p>
+
+<p>
+A consequence is that stacks are no longer segmented, eliminating the "hot split" problem.
+When a stack limit is reached, a new, larger stack is allocated, all active frames for
+the goroutine are copied there, and any pointers into the stack are updated.
+Performance can be noticeably better in some cases and is always more predictable.
+Details are available in <a href="https://golang.org/s/contigstacks">the design document</a>.
+</p>
+
+<p>
+The use of contiguous stacks means that stacks can start smaller without triggering performance issues,
+so the default starting size for a goroutine's stack in 1.4 has been reduced from 8192 bytes to 2048 bytes.
+</p>
+
+<p>
+As preparation for the concurrent garbage collector scheduled for the 1.5 release,
+writes to pointer values in the heap are now done by a function call,
+called a write barrier, rather than directly from the function updating the value.
+In this next release, this will permit the garbage collector to mediate writes to the heap while it is running.
+This change has no semantic effect on programs in 1.4, but was
+included in the release to test the compiler and the resulting performance.
+</p>
+
+<p>
+The implementation of interface values has been modified.
+In earlier releases, the interface contained a word that was either a pointer or a one-word
+scalar value, depending on the type of the concrete object stored.
+This implementation was problematical for the garbage collector,
+so as of 1.4 interface values always hold a pointer.
+In running programs, most interface values were pointers anyway,
+so the effect is minimal, but programs that store integers (for example) in
+interfaces will see more allocations.
+</p>
+
+<p>
+As of Go 1.3, the runtime crashes if it finds a memory word that should contain
+a valid pointer but instead contains an obviously invalid pointer (for example, the value 3).
+Programs that store integers in pointer values may run afoul of this check and crash.
+In Go 1.4, setting the <a href="/pkg/runtime/"><code>GODEBUG</code></a> variable
+<code>invalidptr=0</code> disables
+the crash as a workaround, but we cannot guarantee that future releases will be
+able to avoid the crash; the correct fix is to rewrite code not to alias integers and pointers.
+</p>
+
+<h3 id="asm">Assembly</h3>
+
+<p>
+The language accepted by the assemblers <code>cmd/5a</code>, <code>cmd/6a</code>
+and <code>cmd/8a</code> has had several changes,
+mostly to make it easier to deliver type information to the runtime.
+</p>
+
+<p>
+First, the <code>textflag.h</code> file that defines flags for <code>TEXT</code> directives
+has been copied from the linker source directory to a standard location so it can be
+included with the simple directive
+</p>
+
+<pre>
+#include "textflag.h"
+</pre>
+
+<p>
+The more important changes are in how assembler source can define the necessary
+type information.
+For most programs it will suffice to move data
+definitions (<code>DATA</code> and <code>GLOBL</code> directives)
+out of assembly into Go files
+and to write a Go declaration for each assembly function.
+The <a href="/doc/asm#runtime">assembly document</a> describes what to do.
+</p>
+
+<p>
+<em>Updating</em>:
+Assembly files that include <code>textflag.h</code> from its old
+location will still work, but should be updated.
+For the type information, most assembly routines will need no change,
+but all should be examined.
+Assembly source files that define data,
+functions with non-empty stack frames, or functions that return pointers
+need particular attention.
+A description of the necessary (but simple) changes
+is in the <a href="/doc/asm#runtime">assembly document</a>.
+</p>
+
+<p>
+More information about these changes is in the <a href="/doc/asm">assembly document</a>.
+</p>
+
+<h3 id="gccgo">Status of gccgo</h3>
+
+<p>
+The release schedules for the GCC and Go projects do not coincide.
+GCC release 4.9 contains the Go 1.2 version of gccgo.
+The next release, GCC 5, will likely have the Go 1.4 version of gccgo.
+</p>
+
+<h3 id="internalpackages">Internal packages</h3>
+
+<p>
+Go's package system makes it easy to structure programs into components with clean boundaries,
+but there are only two forms of access: local (unexported) and global (exported).
+Sometimes one wishes to have components that are not exported,
+for instance to avoid acquiring clients of interfaces to code that is part of a public repository
+but not intended for use outside the program to which it belongs.
+</p>
+
+<p>
+The Go language does not have the power to enforce this distinction, but as of Go 1.4 the
+<a href="/cmd/go/"><code>go</code></a> command introduces
+a mechanism to define "internal" packages that may not be imported by packages outside
+the source subtree in which they reside.
+</p>
+
+<p>
+To create such a package, place it in a directory named <code>internal</code> or in a subdirectory of a directory
+named internal.
+When the <code>go</code> command sees an import of a package with <code>internal</code> in its path,
+it verifies that the package doing the import
+is within the tree rooted at the parent of the <code>internal</code> directory.
+For example, a package <code>.../a/b/c/internal/d/e/f</code>
+can be imported only by code in the directory tree rooted at <code>.../a/b/c</code>.
+It cannot be imported by code in <code>.../a/b/g</code> or in any other repository.
+</p>
+
+<p>
+For Go 1.4, the internal package mechanism is enforced for the main Go repository;
+from 1.5 and onward it will be enforced for any repository.
+</p>
+
+<p>
+Full details of the mechanism are in
+<a href="https://golang.org/s/go14internal">the design document</a>.
+</p>
+
+<h3 id="canonicalimports">Canonical import paths</h3>
+
+<p>
+Code often lives in repositories hosted by public services such as <code>github.com</code>,
+meaning that the import paths for packages begin with the name of the hosting service,
+<code>github.com/rsc/pdf</code> for example.
+One can use
+<a href="/cmd/go/#hdr-Remote_import_paths">an existing mechanism</a>
+to provide a "custom" or "vanity" import path such as
+<code>rsc.io/pdf</code>, but
+that creates two valid import paths for the package.
+That is a problem: one may inadvertently import the package through the two
+distinct paths in a single program, which is wasteful;
+miss an update to a package because the path being used is not recognized to be
+out of date;
+or break clients using the old path by moving the package to a different hosting service.
+</p>
+
+<p>
+Go 1.4 introduces an annotation for package clauses in Go source that identify a canonical
+import path for the package.
+If an import is attempted using a path that is not canonical,
+the <a href="/cmd/go/"><code>go</code></a> command
+will refuse to compile the importing package.
+</p>
+
+<p>
+The syntax is simple: put an identifying comment on the package line.
+For our example, the package clause would read:
+</p>
+
+<pre>
+package pdf // import "rsc.io/pdf"
+</pre>
+
+<p>
+With this in place,
+the <code>go</code> command will
+refuse to compile a package that imports <code>github.com/rsc/pdf</code>, 
+ensuring that the code can be moved without breaking users.
+</p>
+
+<p>
+The check is at build time, not download time, so if <code>go</code> <code>get</code>
+fails because of this check, the mis-imported package has been copied to the local machine
+and should be removed manually.
+</p>
+
+<p>
+To complement this new feature, a check has been added at update time to verify
+that the local package's remote repository matches that of its custom import.
+The <code>go</code> <code>get</code> <code>-u</code> command will fail to
+update a package if its remote repository has changed since it was first
+downloaded.
+The new <code>-f</code> flag overrides this check.
+</p>
+
+<p>
+Further information is in
+<a href="https://golang.org/s/go14customimport">the design document</a>.
+</p>
+
+<h3 id="subrepo">Import paths for the subrepositories</h3>
+
+<p>
+The Go project subrepositories (<code>code.google.com/p/go.tools</code> and so on)
+are now available under custom import paths replacing <code>code.google.com/p/go.</code> with <code>golang.org/x/</code>,
+as in <code>golang.org/x/tools</code>.
+We will add canonical import comments to the code around June 1, 2015,
+at which point Go 1.4 and later will stop accepting the old <code>code.google.com</code> paths.
+</p>
+
+<p>
+<em>Updating</em>: All code that imports from subrepositories should change
+to use the new <code>golang.org</code> paths.
+Go 1.0 and later can resolve and import the new paths, so updating will not break
+compatibility with older releases.
+Code that has not updated will stop compiling with Go 1.4 around June 1, 2015.
+</p>
+
+<h3 id="gogenerate">The go generate subcommand</h3>
+
+<p>
+The <a href="/cmd/go/"><code>go</code></a> command has a new subcommand,
+<a href="/cmd/go/#hdr-Generate_Go_files_by_processing_source"><code>go generate</code></a>,
+to automate the running of tools to generate source code before compilation.
+For example, it can be used to run the <a href="/cmd/yacc"><code>yacc</code></a>
+compiler-compiler on a <code>.y</code> file to produce the Go source file implementing the grammar,
+or to automate the generation of <code>String</code> methods for typed constants using the new
+<a href="http://godoc.org/golang.org/x/tools/cmd/stringer">stringer</a>
+tool in the <code>golang.org/x/tools</code> subrepository.
+</p>
+
+<p>
+For more information, see the 
+<a href="https://golang.org/s/go1.4-generate">design document</a>.
+</p>
+
+<h3 id="filenames">Change to file name handling</h3>
+
+<p>
+Build constraints, also known as build tags, control compilation by including or excluding files
+(see the documentation <a href="/pkg/go/build/"><code>/go/build</code></a>).
+Compilation can also be controlled by the name of the file itself by "tagging" the file with
+a suffix (before the <code>.go</code> or <code>.s</code> extension) with an underscore
+and the name of the architecture or operating system.
+For instance, the file <code>gopher_arm.go</code> will only be compiled if the target
+processor is an ARM.
+</p>
+
+<p>
+Before Go 1.4, a file called just <code>arm.go</code> was similarly tagged, but this behavior
+can break sources when new architectures are added, causing files to suddenly become tagged.
+In 1.4, therefore, a file will be tagged in this manner only if the tag (architecture or operating
+system name) is preceded by an underscore.
+</p>
+
+<p>
+<em>Updating</em>: Packages that depend on the old behavior will no longer compile correctly.
+Files with names like <code>windows.go</code> or <code>amd64.go</code> should either
+have explicit build tags added to the source or be renamed to something like
+<code>os_windows.go</code> or <code>support_amd64.go</code>.
+</p>
+
+<h3 id="gocmd">Other changes to the go command</h3>
+
+<p>
+There were a number of minor changes to the
+<a href="/cmd/go/"><code>cmd/go</code></a>
+command worth noting.
+</p>
+
+<ul>
+
+<li>
+Unless <a href="/cmd/cgo/"><code>cgo</code></a> is being used to build the package,
+the <code>go</code> command now refuses to compile C source files,
+since the relevant C compilers
+(<a href="/cmd/6c/"><code>6c</code></a> etc.)
+are intended to be removed from the installation in some future release.
+(They are used today only to build part of the runtime.)
+It is difficult to use them correctly in any case, so any extant uses are likely incorrect,
+so we have disabled them.
+</li>
+
+<li>
+The <a href="/cmd/go/#hdr-Test_packages"><code>go</code> <code>test</code></a>
+subcommand has a new flag, <code>-o</code>, to set the name of the resulting binary,
+corresponding to the same flag in other subcommands.
+The non-functional <code>-file</code> flag has been removed.
+</li>
+
+<li>
+The <a href="/cmd/go/#hdr-Test_packages"><code>go</code> <code>test</code></a>
+subcommand will compile and link all <code>*_test.go</code> files in the package,
+even when there are no <code>Test</code> functions in them. 
+It previously ignored such files.
+</li>
+
+<li>
+The behavior of the
+<a href="/cmd/go/#hdr-Test_packages"><code>go</code> <code>build</code></a>
+subcommand's
+<code>-a</code> flag has been changed for non-development installations.
+For installations running a released distribution, the <code>-a</code> flag will no longer
+rebuild the standard library and commands, to avoid overwriting the installation's files.
+</li>
+
+</ul>
+
+<h3 id="pkg">Changes to package source layout</h3>
+
+<p>
+In the main Go source repository, the source code for the packages was kept in
+the directory <code>src/pkg</code>, which made sense but differed from
+other repositories, including the Go subrepositories.
+In Go 1.4, the<code> pkg</code> level of the source tree is now gone, so for example
+the <a href="/pkg/fmt/"><code>fmt</code></a> package's source, once kept in
+directory <code>src/pkg/fmt</code>, now lives one level higher in <code>src/fmt</code>.
+</p>
+
+<p>
+<em>Updating</em>: Tools like <code>godoc</code> that discover source code
+need to know about the new location. All tools and services maintained by the Go team
+have been updated.
+</p>
+
+
+<h3 id="swig">SWIG</h3>
+
+<p>
+Due to runtime changes in this release, Go 1.4 requires SWIG 3.0.3.
+</p>
+
+<h3 id="misc">Miscellany</h3>
+
+<p>
+The standard repository's top-level <code>misc</code> directory used to contain
+Go support for editors and IDEs: plugins, initialization scripts and so on.
+Maintaining these was becoming time-consuming
+and needed external help because many of the editors listed were not used by
+members of the core team.
+It also required us to make decisions about which plugin was best for a given
+editor, even for editors we do not use.
+</p>
+
+<p>
+The Go community at large is much better suited to managing this information.
+In Go 1.4, therefore, this support has been removed from the repository.
+Instead, there is a curated, informative list of what's available on
+a <a href="//golang.org/wiki/IDEsAndTextEditorPlugins">wiki page</a>.
+</p>
+
+<h2 id="performance">Performance</h2>
+
+<p>
+Most programs will run about the same speed or slightly faster in 1.4 than in 1.3;
+some will be slightly slower.
+There are many changes, making it hard to be precise about what to expect.
+</p>
+
+<p>
+As mentioned above, much of the runtime was translated to Go from C,
+which led to some reduction in heap sizes.
+It also improved performance slightly because the Go compiler is better
+at optimization, due to things like inlining, than the C compiler used to build
+the runtime.
+</p>
+
+<p>
+The garbage collector was sped up, leading to measurable improvements for
+garbage-heavy programs.
+On the other hand, the new write barriers slow things down again, typically
+by about the same amount but, depending on their behavior, some programs
+may be somewhat slower or faster.
+</p>
+
+<p>
+Library changes that affect performance are documented below.
+</p>
+
+<h2 id="library">Changes to the standard library</h2>
+
+<h3 id="new_packages">New packages</h3>
+
+<p>
+There are no new packages in this release.
+</p>
+
+<h3 id="major_library_changes">Major changes to the library</h3>
+
+<h4 id="scanner">bufio.Scanner</h4>
+
+<p>
+The <a href="/pkg/bufio/#Scanner"><code>Scanner</code></a> type in the
+<a href="/pkg/bufio/"><code>bufio</code></a> package
+has had a bug fixed that may require changes to custom
+<a href="/pkg/bufio/#SplitFunc"><code>split functions</code></a>. 
+The bug made it impossible to generate an empty token at EOF; the fix
+changes the end conditions seen by the split function.
+Previously, scanning stopped at EOF if there was no more data.
+As of 1.4, the split function will be called once at EOF after input is exhausted,
+so the split function can generate a final empty token
+as the documentation already promised.
+</p>
+
+<p>
+<em>Updating</em>: Custom split functions may need to be modified to
+handle empty tokens at EOF as desired.
+</p>
+
+<h4 id="syscall">syscall</h4>
+
+<p>
+The <a href="/pkg/syscall/"><code>syscall</code></a> package is now frozen except
+for changes needed to maintain the core repository.
+In particular, it will no longer be extended to support new or different system calls
+that are not used by the core.
+The reasons are described at length in <a href="https://golang.org/s/go1.4-syscall">a
+separate document</a>.
+</p>
+
+<p>
+A new subrepository, <a href="https://golang.org/x/sys">golang.org/x/sys</a>,
+has been created to serve as the location for new developments to support system
+calls on all kernels.
+It has a nicer structure, with three packages that each hold the implementation of
+system calls for one of
+<a href="http://godoc.org/golang.org/x/sys/unix">Unix</a>,
+<a href="http://godoc.org/golang.org/x/sys/windows">Windows</a> and
+<a href="http://godoc.org/golang.org/x/sys/plan9">Plan 9</a>.
+These packages will be curated more generously, accepting all reasonable changes
+that reflect kernel interfaces in those operating systems.
+See the documentation and the article mentioned above for more information.
+</p>
+
+<p>
+<em>Updating</em>: Existing programs are not affected as the <code>syscall</code>
+package is largely unchanged from the 1.3 release.
+Future development that requires system calls not in the <code>syscall</code> package
+should build on <code>golang.org/x/sys</code> instead.
+</p>
+
+<h3 id="minor_library_changes">Minor changes to the library</h3>
+
+<p>
+The following list summarizes a number of minor changes to the library, mostly additions.
+See the relevant package documentation for more information about each change.
+</p>
+
+<ul>
+
+<li>
+The <a href="/pkg/archive/zip/"><code>archive/zip</code></a> package's
+<a href="/pkg/archive/zip/#Writer"><code>Writer</code></a> now supports a
+<a href="/pkg/archive/zip/#Writer.Flush"><code>Flush</code></a> method.
+</li>
+
+<li>
+The <a href="/pkg/compress/flate/"><code>compress/flate</code></a>,
+<a href="/pkg/compress/gzip/"><code>compress/gzip</code></a>,
+and <a href="/pkg/compress/zlib/"><code>compress/zlib</code></a>
+packages now support a <code>Reset</code> method
+for the decompressors, allowing them to reuse buffers and improve performance.
+The <a href="/pkg/compress/gzip/"><code>compress/gzip</code></a> package also has a
+<a href="/pkg/compress/gzip/#Reader.Multistream"><code>Multistream</code></a> method to control support
+for multistream files.
+</li>
+
+<li>
+The <a href="/pkg/crypto/"><code>crypto</code></a> package now has a
+<a href="/pkg/crypto/#Signer"><code>Signer</code></a> interface, implemented by the
+<code>PrivateKey</code> types in
+<a href="/pkg/crypto/ecdsa"><code>crypto/ecdsa</code></a> and
+<a href="/pkg/crypto/rsa"><code>crypto/rsa</code></a>.
+</li>
+
+<li>
+The <a href="/pkg/crypto/tls/"><code>crypto/tls</code></a> package
+now supports ALPN as defined in <a href="http://tools.ietf.org/html/rfc7301">RFC 7301</a>.
+</li>
+
+<li>
+The <a href="/pkg/crypto/tls/"><code>crypto/tls</code></a> package
+now supports programmatic selection of server certificates
+through the new <a href="/pkg/crypto/tls/#Config.CertificateForName"><code>CertificateForName</code></a> function
+of the <a href="/pkg/crypto/tls/#Config"><code>Config</code></a> struct.
+</li>
+
+<li>
+Also in the crypto/tls package, the server now supports 
+<a href="https://tools.ietf.org/html/draft-ietf-tls-downgrade-scsv-00">TLS_FALLBACK_SCSV</a>
+to help clients detect fallback attacks.
+(The Go client does not support fallback at all, so it is not vulnerable to
+those attacks.)
+</li>
+
+<li>
+The <a href="/pkg/database/sql/"><code>database/sql</code></a> package can now list all registered
+<a href="/pkg/database/sql/#Drivers"><code>Drivers</code></a>.
+</li>
+
+<li>
+The <a href="/pkg/debug/dwarf/"><code>debug/dwarf</code></a> package now supports
+<a href="/pkg/debug/dwarf/#UnspecifiedType"><code>UnspecifiedType</code></a>s.
+</li>
+
+<li>
+In the <a href="/pkg/encoding/asn1/"><code>encoding/asn1</code></a> package,
+optional elements with a default value will now only be omitted if they have that value.
+</li>
+
+<li>
+The <a href="/pkg/encoding/csv/"><code>encoding/csv</code></a> package no longer
+quotes empty strings but does quote the end-of-data marker <code>\.</code> (backslash dot).
+This is permitted by the definition of CSV and allows it to work better with Postgres.
+</li>
+
+<li>
+The <a href="/pkg/encoding/gob/"><code>encoding/gob</code></a> package has been rewritten to eliminate
+the use of unsafe operations, allowing it to be used in environments that do not permit use of the
+<a href="/pkg/unsafe/"><code>unsafe</code></a> package.
+For typical uses it will be 10-30% slower, but the delta is dependent on the type of the data and
+in some cases, especially involving arrays, it can be faster.
+There is no functional change.
+</li>
+
+<li>
+The <a href="/pkg/encoding/xml/"><code>encoding/xml</code></a> package's
+<a href="/pkg/encoding/xml/#Decoder"><code>Decoder</code></a> can now report its input offset.
+</li>
+
+<li>
+In the <a href="/pkg/fmt/"><code>fmt</code></a> package,
+formatting of pointers to maps has changed to be consistent with that of pointers
+to structs, arrays, and so on.
+For instance, <code>&amp;map[string]int{"one":</code> <code>1}</code> now prints by default as
+<code>&amp;map[one:</code> <code>1]</code> rather than as a hexadecimal pointer value.
+</li>
+
+<li>
+The <a href="/pkg/image/"><code>image</code></a> package's
+<a href="/pkg/image/#Image"><code>Image</code></a>
+implementations like
+<a href="/pkg/image/#RGBA"><code>RGBA</code></a> and
+<a href="/pkg/image/#Gray"><code>Gray</code></a> have specialized
+<a href="/pkg/image/#RGBA.RGBAAt"><code>RGBAAt</code></a> and
+<a href="/pkg/image/#Gray.GrayAt"><code>GrayAt</code></a> methods alongside the general
+<a href="/pkg/image/#Image.At"><code>At</code></a> method.
+</li>
+
+<li>

+<h2 id="introduction">Introduction to Go 1.6</h2>
+
+<p>
+The latest Go release, version 1.6, arrives six months after 1.5.
+Most of its changes are in the implementation of the language, runtime, and libraries.
+There are no changes to the language specification.
+As always, the release maintains the Go 1 <a href="/doc/go1compat.html">promise of compatibility</a>.
+We expect almost all Go programs to continue to compile and run as before.
+</p>
+
+<p>
+The release adds new ports to <a href="#ports">Linux on 64-bit MIPS and Android on 32-bit x86</a>;
+defined and enforced <a href="#cgo">rules for sharing Go pointers with C</a>;
+transparent, automatic <a href="#http2">support for HTTP/2</a>;
+and a new mechanism for <a href="#template">template reuse</a>.
+</p>
+
+<h2 id="language">Changes to the language</h2>
+
+<p>
+There are no language changes in this release.
+</p>
+
+<h2 id="ports">Ports</h2>
+
+<p>
+Go 1.6 adds experimental ports to
+Linux on 64-bit MIPS (<code>linux/mips64</code> and <code>linux/mips64le</code>).
+These ports support <code>cgo</code> but only with internal linking.
+</p>
+
+<p>
+Go 1.6 also adds an experimental port to Android on 32-bit x86 (<code>android/386</code>).
+</p>
+
+<p>
+On FreeBSD, Go 1.6 defaults to using <code>clang</code>, not <code>gcc</code>, as the external C compiler.
+</p>
+
+<p>
+On Linux on little-endian 64-bit PowerPC (<code>linux/ppc64le</code>),
+Go 1.6 now supports <code>cgo</code> with external linking and
+is roughly feature complete.
+</p>
+
+<p>
+On NaCl, Go 1.5 required SDK version pepper-41.
+Go 1.6 adds support for later SDK versions.
+</p>
+
+<p>
+On 32-bit x86 systems using the <code>-dynlink</code> or <code>-shared</code> compilation modes,
+the register CX is now overwritten by certain memory references and should
+be avoided in hand-written assembly.
+See the <a href="/doc/asm#x86">assembly documentation</a> for details.
+</p>
+
+<h2 id="tools">Tools</h2>
+
+<h3 id="cgo">Cgo</h3>
+
+<p>
+There is one major change to <a href="/cmd/cgo/"><code>cgo</code></a>, along with one minor change.
+</p>
+
+<p>
+The major change is the definition of rules for sharing Go pointers with C code,
+to ensure that such C code can coexist with Go's garbage collector.
+Briefly, Go and C may share memory allocated by Go
+when a pointer to that memory is passed to C as part of a <code>cgo</code> call,
+provided that the memory itself contains no pointers to Go-allocated memory,
+and provided that C does not retain the pointer after the call returns.
+These rules are checked by the runtime during program execution:
+if the runtime detects a violation, it prints a diagnosis and crashes the program.
+The checks can be disabled by setting the environment variable
+<code>GODEBUG=cgocheck=0</code>, but note that the vast majority of
+code identified by the checks is subtly incompatible with garbage collection
+in one way or another.
+Disabling the checks will typically only lead to more mysterious failure modes.
+Fixing the code in question should be strongly preferred
+over turning off the checks.
+See the <a href="/cmd/cgo/#hdr-Passing_pointers"><code>cgo</code> documentation</a> for more details.
+</p>
+
+<p>
+The minor change is
+the addition of explicit <code>C.complexfloat</code> and <code>C.complexdouble</code> types,
+separate from Go's <code>complex64</code> and <code>complex128</code>.
+Matching the other numeric types, C's complex types and Go's complex type are
+no longer interchangeable.
+</p>
+
+<h3 id="compiler">Compiler Toolchain</h3>
+
+<p>
+The compiler toolchain is mostly unchanged.
+Internally, the most significant change is that the parser is now hand-written
+instead of generated from <a href="/cmd/yacc/">yacc</a>.
+</p>
+
+<p>
+The compiler, linker, and <code>go</code> command have a new flag <code>-msan</code>,
+analogous to <code>-race</code> and only available on linux/amd64,
+that enables interoperation with the <a href="http://clang.llvm.org/docs/MemorySanitizer.html">Clang MemorySanitizer</a>.
+Such interoperation is useful mainly for testing a program containing suspect C or C++ code.
+</p>
+
+<p>
+The linker has a new option <code>-libgcc</code> to set the expected location
+of the C compiler support library when linking <a href="/cmd/cgo/"><code>cgo</code></a> code.
+The option is only consulted when using <code>-linkmode=internal</code>,
+and it may be set to <code>none</code> to disable the use of a support library.
+</p>
+
+<p>
+The implementation of <a href="/doc/go1.5#link">build modes started in Go 1.5</a> has been expanded to more systems.
+This release adds support for the <code>c-shared</code> mode on <code>android/386</code>, <code>android/amd64</code>,
+<code>android/arm64</code>, <code>linux/386</code>, and <code>linux/arm64</code>;
+for the <code>shared</code> mode on <code>linux/386</code>, <code>linux/arm</code>, <code>linux/amd64</code>, and <code>linux/ppc64le</code>;
+and for the new <code>pie</code> mode (generating position-independent executables) on
+<code>android/386</code>, <code>android/amd64</code>, <code>android/arm</code>, <code>android/arm64</code>, <code>linux/386</code>,
+<code>linux/amd64</code>, <code>linux/arm</code>, <code>linux/arm64</code>, and <code>linux/ppc64le</code>.
+See the <a href="https://golang.org/s/execmodes">design document</a> for details.
+</p>
+
+<p>
+As a reminder, the linker's <code>-X</code> flag changed in Go 1.5.
+In Go 1.4 and earlier, it took two arguments, as in
+</p>
+
+<pre>
+-X importpath.name value
+</pre>
+
+<p>
+Go 1.5 added an alternative syntax using a single argument
+that is itself a <code>name=value</code> pair:
+</p>
+
+<pre>
+-X importpath.name=value
+</pre>
+
+<p>
+In Go 1.5 the old syntax was still accepted, after printing a warning
+suggesting use of the new syntax instead.
+Go 1.6 continues to accept the old syntax and print the warning.
+Go 1.7 will remove support for the old syntax.
+</p>
+
+<h3 id="gccgo">Gccgo</h3>
+
+<p>
+The release schedules for the GCC and Go projects do not coincide.
+GCC release 5 contains the Go 1.4 version of gccgo.
+The next release, GCC 6, will have the Go 1.6.1 version of gccgo.
+</p>
+
+<h3 id="go_command">Go command</h3>
+
+<p>
+The <a href="/cmd/go"><code>go</code></a> command's basic operation
+is unchanged, but there are a number of changes worth noting.
+</p>
+
+<p>
+Go 1.5 introduced experimental support for vendoring,
+enabled by setting the <code>GO15VENDOREXPERIMENT</code> environment variable to <code>1</code>.
+Go 1.6 keeps the vendoring support, no longer considered experimental,
+and enables it by default.
+It can be disabled explicitly by setting
+the <code>GO15VENDOREXPERIMENT</code> environment variable to <code>0</code>.
+Go 1.7 will remove support for the environment variable.
+</p>
+
+<p>
+The most likely problem caused by enabling vendoring by default happens
+in source trees containing an existing directory named <code>vendor</code> that
+does not expect to be interpreted according to new vendoring semantics.
+In this case, the simplest fix is to rename the directory to anything other
+than <code>vendor</code> and update any affected import paths.
+</p>
+
+<p>
+For details about vendoring,
+see the documentation for the <a href="/cmd/go/#hdr-Vendor_Directories"><code>go</code> command</a>
+and the <a href="https://golang.org/s/go15vendor">design document</a>.
+</p>
+
+<p>
+There is a new build flag, <code>-msan</code>,
+that compiles Go with support for the LLVM memory sanitizer.
+This is intended mainly for use when linking against C or C++ code
+that is being checked with the memory sanitizer.
+</p>
+
+<h3 id="doc_command">Go doc command</h3>
+
+<p>
+Go 1.5 introduced the
+<a href="/cmd/go/#hdr-Show_documentation_for_package_or_symbol"><code>go doc</code></a> command,
+which allows references to packages using only the package name, as in
+<code>go</code> <code>doc</code> <code>http</code>.
+In the event of ambiguity, the Go 1.5 behavior was to use the package
+with the lexicographically earliest import path.
+In Go 1.6, ambiguity is resolved by preferring import paths with
+fewer elements, breaking ties using lexicographic comparison.
+An important effect of this change is that original copies of packages
+are now preferred over vendored copies.
+Successful searches also tend to run faster.
+</p>
+
+<h3 id="vet_command">Go vet command</h3>
+
+<p>
+The <a href="/cmd/vet"><code>go vet</code></a> command now diagnoses
+passing function or method values as arguments to <code>Printf</code>,
+such as when passing <code>f</code> where <code>f()</code> was intended.
+</p>
+
+<h2 id="performance">Performance</h2>
+
+<p>
+As always, the changes are so general and varied that precise statements
+about performance are difficult to make.
+Some programs may run faster, some slower.
+On average the programs in the Go 1 benchmark suite run a few percent faster in Go 1.6
+than they did in Go 1.5.
+The garbage collector's pauses are even lower than in Go 1.5,
+especially for programs using
+a large amount of memory.
+</p>
+
+<p>
+There have been significant optimizations bringing more than 10% improvements
+to implementations of the
+<a href="/pkg/compress/bzip2/"><code>compress/bzip2</code></a>,
+<a href="/pkg/compress/gzip/"><code>compress/gzip</code></a>,
+<a href="/pkg/crypto/aes/"><code>crypto/aes</code></a>,
+<a href="/pkg/crypto/elliptic/"><code>crypto/elliptic</code></a>,
+<a href="/pkg/crypto/ecdsa/"><code>crypto/ecdsa</code></a>, and
+<a href="/pkg/sort/"><code>sort</code></a> packages.
+</p>
+
+<h2 id="library">Core library</h2>
+
+<h3 id="http2">HTTP/2</h3>
+
+<p>
+Go 1.6 adds transparent support in the
+<a href="/pkg/net/http/"><code>net/http</code></a> package
+for the new <a href="https://http2.github.io/">HTTP/2 protocol</a>.
+Go clients and servers will automatically use HTTP/2 as appropriate when using HTTPS.
+There is no exported API specific to details of the HTTP/2 protocol handling,
+just as there is no exported API specific to HTTP/1.1.
+</p>
+
+<p>
+Programs that must disable HTTP/2 can do so by setting
+<a href="/pkg/net/http/#Transport"><code>Transport.TLSNextProto</code></a> (for clients)
+or
+<a href="/pkg/net/http/#Server"><code>Server.TLSNextProto</code></a> (for servers)
+to a non-nil, empty map.
+</p>
+
+<p>
+Programs that must adjust HTTP/2 protocol-specific details can import and use
+<a href="https://golang.org/x/net/http2"><code>golang.org/x/net/http2</code></a>,
+in particular its
+<a href="https://godoc.org/golang.org/x/net/http2/#ConfigureServer">ConfigureServer</a>
+and
+<a href="https://godoc.org/golang.org/x/net/http2/#ConfigureTransport">ConfigureTransport</a>
+functions.
+</p>
+
+<h3 id="runtime">Runtime</h3>
+
+<p>
+The runtime has added lightweight, best-effort detection of concurrent misuse of maps.
+As always, if one goroutine is writing to a map, no other goroutine should be
+reading or writing the map concurrently.
+If the runtime detects this condition, it prints a diagnosis and crashes the program.
+The best way to find out more about the problem is to run the program
+under the
+<a href="https://blog.golang.org/race-detector">race detector</a>,
+which will more reliably identify the race
+and give more detail.
+</p>
+
+<p>
+For program-ending panics, the runtime now by default
+prints only the stack of the running goroutine,
+not all existing goroutines.
+Usually only the current goroutine is relevant to a panic,
+so omitting the others significantly reduces irrelevant output
+in a crash message.
+To see the stacks from all goroutines in crash messages, set the environment variable
+<code>GOTRACEBACK</code> to <code>all</code>
+or call
+<a href="/pkg/runtime/debug/#SetTraceback"><code>debug.SetTraceback</code></a>
+before the crash, and rerun the program.
+See the <a href="/pkg/runtime/#hdr-Environment_Variables">runtime documentation</a> for details.
+</p>
+
+<p>
+<em>Updating</em>:
+Uncaught panics intended to dump the state of the entire program,
+such as when a timeout is detected or when explicitly handling a received signal,
+should now call <code>debug.SetTraceback("all")</code> before panicking.
+Searching for uses of
+<a href="/pkg/os/signal/#Notify"><code>signal.Notify</code></a> may help identify such code.
+</p>
+
+<p>
+On Windows, Go programs in Go 1.5 and earlier forced
+the global Windows timer resolution to 1ms at startup
+by calling <code>timeBeginPeriod(1)</code>.
+Go no longer needs this for good scheduler performance,
+and changing the global timer resolution caused problems on some systems,
+so the call has been removed.
+</p>
+
+<p>
+When using <code>-buildmode=c-archive</code> or
+<code>-buildmode=c-shared</code> to build an archive or a shared
+library, the handling of signals has changed.
+In Go 1.5 the archive or shared library would install a signal handler
+for most signals.
+In Go 1.6 it will only install a signal handler for the
+synchronous signals needed to handle run-time panics in Go code:
+SIGBUS, SIGFPE, SIGSEGV.
+See the <a href="/pkg/os/signal">os/signal</a> package for more
+details.
+</p>
+
+<h3 id="reflect">Reflect</h3>
+
+<p>
+The
+<a href="/pkg/reflect/"><code>reflect</code></a> package has
+<a href="https://golang.org/issue/12367">resolved a long-standing incompatibility</a>
+between the gc and gccgo toolchains
+regarding embedded unexported struct types containing exported fields.
+Code that walks data structures using reflection, especially to implement
+serialization in the spirit
+of the
+<a href="/pkg/encoding/json/"><code>encoding/json</code></a> and
+<a href="/pkg/encoding/xml/"><code>encoding/xml</code></a> packages,
+may need to be updated.
+</p>
+
+<p>
+The problem arises when using reflection to walk through
+an embedded unexported struct-typed field
+into an exported field of that struct.
+In this case, <code>reflect</code> had incorrectly reported
+the embedded field as exported, by returning an empty <code>Field.PkgPath</code>.
+Now it correctly reports the field as unexported
+but ignores that fact when evaluating access to exported fields
+contained within the struct.
+</p>
+
+<p>
+<em>Updating</em>:
+Typically, code that previously walked over structs and used
+</p>
+
+<pre>
+f.PkgPath != ""
+</pre>
+
+<p>
+to exclude inaccessible fields
+should now use
+</p>
+
+<pre>
+f.PkgPath != "" &amp;&amp; !f.Anonymous
+</pre>
+
+<p>
+For example, see the changes to the implementations of
+<a href="https://go-review.googlesource.com/#/c/14011/2/src/encoding/json/encode.go"><code>encoding/json</code></a> and
+<a href="https://go-review.googlesource.com/#/c/14012/2/src/encoding/xml/typeinfo.go"><code>encoding/xml</code></a>.
+</p>
+
+<h3 id="sort">Sorting</h3>
+
+<p>
+In the
+<a href="/pkg/sort/"><code>sort</code></a>
+package,
+the implementation of
+<a href="/pkg/sort/#Sort"><code>Sort</code></a>
+has been rewritten to make about 10% fewer calls to the
+<a href="/pkg/sort/#Interface"><code>Interface</code></a>'s
+<code>Less</code> and <code>Swap</code>
+methods, with a corresponding overall time savings.
+The new algorithm does choose a different ordering than before
+for values that compare equal (those pairs for which <code>Less(i,</code> <code>j)</code> and <code>Less(j,</code> <code>i)</code> are false).
+</p>
+
+<p>
+<em>Updating</em>:
+The definition of <code>Sort</code> makes no guarantee about the final order of equal values,
+but the new behavior may still break programs that expect a specific order.
+Such programs should either refine their <code>Less</code> implementations
+to report the desired order
+or should switch to
+<a href="/pkg/sort/#Stable"><code>Stable</code></a>,
+which preserves the original input order
+of equal values.
+</p>
+
+<h3 id="template">Templates</h3>
+
+<p>
+In the
+<a href="/pkg/text/template/">text/template</a> package,
+there are two significant new features to make writing templates easier.
+</p>
+
+<p>
+First, it is now possible to <a href="/pkg/text/template/#hdr-Text_and_spaces">trim spaces around template actions</a>,
+which can make template definitions more readable.
+A minus sign at the beginning of an action says to trim space before the action,
+and a minus sign at the end of an action says to trim space after the action.
+For example, the template
+</p>
+
+<pre>
+{{"{{"}}23 -}}
+   &lt;
+{{"{{"}}- 45}}
+</pre>
+
+<p>
+formats as <code>23&lt;45</code>.
+</p>
+
+<p>
+Second, the new <a href="/pkg/text/template/#hdr-Actions"><code>{{"{{"}}block}}</code> action</a>,
+combined with allowing redefinition of named templates,
+provides a simple way to define pieces of a template that
+can be replaced in different instantiations.
+There is <a href="/pkg/text/template/#example_Template_block">an example</a>
+in the <code>text/template</code> package that demonstrates this new feature.
+</p>
+
+<h3 id="minor_library_changes">Minor changes to the library</h3>
+
+<ul>
+
+<li>
+The <a href="/pkg/archive/tar/"><code>archive/tar</code></a> package's
+implementation corrects many bugs in rare corner cases of the file format.
+One visible change is that the
+<a href="/pkg/archive/tar/#Reader"><code>Reader</code></a> type's
+<a href="/pkg/archive/tar/#Reader.Read"><code>Read</code></a> method
+now presents the content of special file types as being empty,
+returning <code>io.EOF</code> immediately.
+</li>
+
+<li>
+In the <a href="/pkg/archive/zip/"><code>archive/zip</code></a> package, the
+<a href="/pkg/archive/zip/#Reader"><code>Reader</code></a> type now has a
+<a href="/pkg/archive/zip/#Reader.RegisterDecompressor"><code>RegisterDecompressor</code></a> method,
+and the
+<a href="/pkg/archive/zip/#Writer"><code>Writer</code></a> type now has a
+<a href="/pkg/archive/zip/#Writer.RegisterCompressor"><code>RegisterCompressor</code></a> method,
+enabling control over compression options for individual zip files.
+These take precedence over the pre-existing global
+<a href="/pkg/archive/zip/#RegisterDecompressor"><code>RegisterDecompressor</code></a> and
+<a href="/pkg/archive/zip/#RegisterCompressor"><code>RegisterCompressor</code></a> functions.
+</li>
+
+<li>
+The <a href="/pkg/bufio/"><code>bufio</code></a> package's
+<a href="/pkg/bufio/#Scanner"><code>Scanner</code></a> type now has a
+<a href="/pkg/bufio/#Scanner.Buffer"><code>Buffer</code></a> method,
+to specify an initial buffer and maximum buffer size to use during scanning.
+This makes it possible, when needed, to scan tokens larger than
+<code>MaxScanTokenSize</code>.
+Also for the <code>Scanner</code>, the package now defines the
+<a href="/pkg/bufio/#ErrFinalToken"><code>ErrFinalToken</code></a> error value, for use by
+<a href="/pkg/bufio/#SplitFunc">split functions</a> to abort processing or to return a final empty token.
+</li>
+
+<li>
+The <a href="/pkg/compress/flate/"><code>compress/flate</code></a> package
+has deprecated its
+<a href="/pkg/compress/flate/#ReadError"><code>ReadError</code></a> and
+<a href="/pkg/compress/flate/#WriteError"><code>WriteError</code></a> error implementations.
+In Go 1.5 they were only rarely returned when an error was encountered;
+now they are never returned, although they remain defined for compatibility.
+</li>
+
+<li>
+The <a href="/pkg/compress/flate/"><code>compress/flate</code></a>,
+<a href="/pkg/compress/gzip/"><code>compress/gzip</code></a>, and
+<a href="/pkg/compress/zlib/"><code>compress/zlib</code></a> packages
+now report
+<a href="/pkg/io/#ErrUnexpectedEOF"><code>io.ErrUnexpectedEOF</code></a> for truncated input streams, instead of
+<a href="/pkg/io/#EOF"><code>io.EOF</code></a>.
+</li>
+
+<li>
+The <a href="/pkg/crypto/cipher/"><code>crypto/cipher</code></a> package now
+overwrites the destination buffer in the event of a GCM decryption failure.
+This is to allow the AESNI code to avoid using a temporary buffer.
+</li>
+
+<li>
+The <a href="/pkg/crypto/tls/"><code>crypto/tls</code></a> package
+has a variety of minor changes.
+It now allows
+<a href="/pkg/crypto/tls/#Listen"><code>Listen</code></a>
+to succeed when the
+<a href="/pkg/crypto/tls/#Config"><code>Config</code></a>
+has a nil <code>Certificates</code>, as long as the <code>GetCertificate</code> callback is set,
+it adds support for RSA with AES-GCM cipher suites,
+and
+it adds a
+<a href="/pkg/crypto/tls/#RecordHeaderError"><code>RecordHeaderError</code></a>
+to allow clients (in particular, the <a href="/pkg/net/http/"><code>net/http</code></a> package)
+to report a better error when attempting a TLS connection to a non-TLS server.
+</li>
+
+<li>
+The <a href="/pkg/crypto/x509/"><code>crypto/x509</code></a> package
+now permits certificates to contain negative serial numbers
+(technically an error, but unfortunately common in practice),
+and it defines a new
+<a href="/pkg/crypto/x509/#InsecureAlgorithmError"><code>InsecureAlgorithmError</code></a>
+to give a better error message when rejecting a certificate
+signed with an insecure algorithm like MD5.
+</li>
+
+<li>
+The <a href="/pkg/debug/dwarf"><code>debug/dwarf</code></a> and
+<a href="/pkg/debug/elf/"><code>debug/elf</code></a> packages
+together add support for compressed DWARF sections.
+User code needs no updating: the sections are decompressed automatically when read.
+</li>
+
+<li>
+The <a href="/pkg/debug/elf/"><code>debug/elf</code></a> package
+adds support for general compressed ELF sections.
+User code needs no updating: the sections are decompressed automatically when read.
+However, compressed
+<a href="/pkg/debug/elf/#Section"><code>Sections</code></a> do not support random access:
+they have a nil <code>ReaderAt</code> field.
+</li>
+
+<li>
+The <a href="/pkg/encoding/asn1/"><code>encoding/asn1</code></a> package
+now exports
+<a href="/pkg/encoding/asn1/#pkg-constants">tag and class constants</a>
+useful for advanced parsing of ASN.1 structures.
+</li>
+
+<li>
+Also in the <a href="/pkg/encoding/asn1/"><code>encoding/asn1</code></a> package,
+<a href="/pkg/encoding/asn1/#Unmarshal"><code>Unmarshal</code></a> now rejects various non-standard integer and length encodings.
+</li>
+
+<li>
+The <a href="/pkg/encoding/base64"><code>encoding/base64</code></a> package's
+<a href="/pkg/encoding/base64/#Decoder"><code>Decoder</code></a> has been fixed
+to process the final bytes of its input. Previously it processed as many four-byte tokens as
+possible but ignored the remainder, up to three bytes.
+The <code>Decoder</code> therefore now handles inputs in unpadded encodings (like
+<a href="/pkg/encoding/base64/#RawURLEncoding">RawURLEncoding</a>) correctly,
+but it also rejects inputs in padded encodings that are truncated or end with invalid bytes,
+such as trailing spaces.
+</li>
+
+<li>
+The <a href="/pkg/encoding/json/"><code>encoding/json</code></a> package
+now checks the syntax of a
+<a href="/pkg/encoding/json/#Number"><code>Number</code></a>
+before marshaling it, requiring that it conforms to the JSON specification for numeric values.
+As in previous releases, the zero <code>Number</code> (an empty string) is marshaled as a literal 0 (zero).
+</li>
+
+<li>
+The <a href="/pkg/encoding/xml/"><code>encoding/xml</code></a> package's
+<a href="/pkg/encoding/xml/#Marshal"><code>Marshal</code></a>
+function now supports a <code>cdata</code> attribute, such as <code>chardata</code>
+but encoding its argument in one or more <code>&lt;![CDATA[ ... ]]&gt;</code> tags.
+</li>
+
+<li>
+Also in the <a href="/pkg/encoding/xml/"><code>encoding/xml</code></a> package,
+<a href="/pkg/encoding/xml/#Decoder"><code>Decoder</code></a>'s
+<a href="/pkg/encoding/xml/#Decoder.Token"><code>Token</code></a> method
+now reports an error when encountering EOF before seeing all open tags closed,
+consistent with its general requirement that tags in the input be properly matched.
+To avoid that requirement, use
+<a href="/pkg/encoding/xml/#Decoder.RawToken"><code>RawToken</code></a>.
+</li>
+
+<li>
+The <a href="/pkg/fmt/"><code>fmt</code></a> package now allows
+any integer type as an argument to
+<a href="/pkg/fmt/#Printf"><code>Printf</code></a>'s <code>*</code> width and precision specification.
+In previous releases, the argument to <code>*</code> was required to have type <code>int</code>.
+</li>
+
+<li>
+Also in the <a href="/pkg/fmt/"><code>fmt</code></a> package,
+<a href="/pkg/fmt/#Scanf"><code>Scanf</code></a> can now scan hexadecimal strings using %X, as an alias for %x.
+Both formats accept any mix of upper- and lower-case hexadecimal.
+</li>
+
+<li>
+The <a href="/pkg/image/"><code>image</code></a>
+and
+<a href="/pkg/image/color/"><code>image/color</code></a> packages
+add
+<a href="/pkg/image/#NYCbCrA"><code>NYCbCrA</code></a>
+and
+<a href="/pkg/image/color/#NYCbCrA"><code>NYCbCrA</code></a>
+types, to support Y'CbCr images with non-premultiplied alpha.
+</li>
+
+<li>
+The <a href="/pkg/io/"><code>io</code></a> package's
+<a href="/pkg/io/#MultiWriter"><code>MultiWriter</code></a>
+implementation now implements a <code>WriteString</code> method,
+for use by
+<a href="/pkg/io/#WriteString"><code>WriteString</code></a>.
+</li>
+
+<li>
+In the <a href="/pkg/math/big/"><code>math/big</code></a> package,
+<a href="/pkg/math/big/#Int"><code>Int</code></a> adds
+<a href="/pkg/math/big/#Int.Append"><code>Append</code></a>
+and
+<a href="/pkg/math/big/#Int.Text"><code>Text</code></a>
+methods to give more control over printing.
+</li>
+
+<li>
+Also in the <a href="/pkg/math/big/"><code>math/big</code></a> package,
+<a href="/pkg/math/big/#Float"><code>Float</code></a> now implements
+<a href="/pkg/encoding/#TextMarshaler"><code>encoding.TextMarshaler</code></a> and
+<a href="/pkg/encoding/#TextUnmarshaler"><code>encoding.TextUnmarshaler</code></a>,
+allowing it to be serialized in a natural form by the
+<a href="/pkg/encoding/json/"><code>encoding/json</code></a> and
+<a href="/pkg/encoding/xml/"><code>encoding/xml</code></a> packages.
+</li>
+
+<li>
+Also in the <a href="/pkg/math/big/"><code>math/big</code></a> package,
+<a href="/pkg/math/big/#Float"><code>Float</code></a>'s
+<a href="/pkg/math/big/#Float.Append"><code>Append</code></a> method now supports the special precision argument -1.
+As in
+<a href="/pkg/strconv/#ParseFloat"><code>strconv.ParseFloat</code></a>,
+precision -1 means to use the smallest number of digits necessary such that
+<a href="/pkg/math/big/#Float.Parse"><code>Parse</code></a>
+reading the result into a <code>Float</code> of the same precision
+will yield the original value.
+</li>
+
+<li>
+The <a href="/pkg/math/rand/"><code>math/rand</code></a> package
+adds a
+<a href="/pkg/math/rand/#Read"><code>Read</code></a>
+function, and likewise
+<a href="/pkg/math/rand/#Rand"><code>Rand</code></a> adds a
+<a href="/pkg/math/rand/#Rand.Read"><code>Read</code></a> method.
+These make it easier to generate pseudorandom test data.
+Note that, like the rest of the package,
+these should not be used in cryptographic settings;
+for such purposes, use the <a href="/pkg/crypto/rand/"><code>crypto/rand</code></a> package instead.
+</li>
+
+<li>
+The <a href="/pkg/net/"><code>net</code></a> package's
+<a href="/pkg/net/#ParseMAC"><code>ParseMAC</code></a> function now accepts 20-byte IP-over-InfiniBand (IPoIB) link-layer addresses.
+</li>
+
+
+<li>
+Also in the <a href="/pkg/net/"><code>net</code></a> package,
+there have been a few changes to DNS lookups.
+First, the
+<a href="/pkg/net/#DNSError"><code>DNSError</code></a> error implementation now implements
+<a href="/pkg/net/#Error"><code>Error</code></a>,
+and in particular its new
+<a href="/pkg/net/#DNSError.IsTemporary"><code>IsTemporary</code></a>
+method returns true for DNS server errors.
+Second, DNS lookup functions such as
+<a href="/pkg/net/#LookupAddr"><code>LookupAddr</code></a>
+now return rooted domain names (with a trailing dot)
+on Plan 9 and Windows, to match the behavior of Go on Unix systems.
+</li>
+
+<li>
+The <a href="/pkg/net/http/"><code>net/http</code></a> package has
+a number of minor additions beyond the HTTP/2 support already discussed.
+First, the
+<a href="/pkg/net/http/#FileServer"><code>FileServer</code></a> now sorts its generated directory listings by file name.
+Second, the
+<a href="/pkg/net/http/#ServeFile"><code>ServeFile</code></a> function now refuses to serve a result
+if the request's URL path contains &ldquo;..&rdquo; (dot-dot) as a path element.
+Programs should typically use <code>FileServer</code> and 
+<a href="/pkg/net/http/#Dir"><code>Dir</code></a>
+instead of calling <code>ServeFile</code> directly.
+Programs that need to serve file content in response to requests for URLs containing dot-dot can 
+still call <a href="/pkg/net/http/#ServeContent"><code>ServeContent</code></a>.
+Third, the
+<a href="/pkg/net/http/#Client"><code>Client</code></a> now allows user code to set the
+<code>Expect:</code> <code>100-continue</code> header (see
+<a href="/pkg/net/http/#Transport"><code>Transport.ExpectContinueTimeout</code></a>).
+Fourth, there are
+<a href="/pkg/net/http/#pkg-constants">five new error codes</a>:
+<code>StatusPreconditionRequired</code> (428),
+<code>StatusTooManyRequests</code> (429),
+<code>StatusRequestHeaderFieldsTooLarge</code> (431), and
+<code>StatusNetworkAuthenticationRequired</code> (511) from RFC 6585,
+as well as the recently-approved
+<code>StatusUnavailableForLegalReasons</code> (451).
+Fifth, the implementation and documentation of
+<a href="/pkg/net/http/#CloseNotifier"><code>CloseNotifier</code></a>
+has been substantially changed.
+The <a href="/pkg/net/http/#Hijacker"><code>Hijacker</code></a>
+interface now works correctly on connections that have previously
+been used with <code>CloseNotifier</code>.
+The documentation now describes when <code>CloseNotifier</code>
+is expected to work.
+</li>
+
+<li>
+Also in the <a href="/pkg/net/http/"><code>net/http</code></a> package,
+there are a few changes related to the handling of a
+<a href="/pkg/net/http/#Request"><code>Request</code></a> data structure with its <code>Method</code> field set to the empty string.
+An empty <code>Method</code> field has always been documented as an alias for <code>"GET"</code>
+and it remains so.
+However, Go 1.6 fixes a few routines that did not treat an empty
+<code>Method</code> the same as an explicit <code>"GET"</code>.
+Most notably, in previous releases
+<a href="/pkg/net/http/#Client"><code>Client</code></a> followed redirects only with
+<code>Method</code> set explicitly to <code>"GET"</code>;
+in Go 1.6 <code>Client</code> also follows redirects for the empty <code>Method</code>.
+Finally,
+<a href="/pkg/net/http/#NewRequest"><code>NewRequest</code></a> accepts a <code>method</code> argument that has not been
+documented as allowed to be empty.
+In past releases, passing an empty <code>method</code> argument resulted
+in a <code>Request</code> with an empty <code>Method</code> field.
+In Go 1.6, the resulting <code>Request</code> always has an initialized
+<code>Method</code> field: if its argument is an empty string, <code>NewRequest</code>
+sets the <code>Method</code> field in the returned <code>Request</code> to <code>"GET"</code>.
+</li>
+
+<li>
+The <a href="/pkg/net/http/httptest/"><code>net/http/httptest</code></a> package's
+<a href="/pkg/net/http/httptest/#ResponseRecorder"><code>ResponseRecorder</code></a> now initializes a default Content-Type header
+using the same content-sniffing algorithm as in
+<a href="/pkg/net/http/#Server"><code>http.Server</code></a>.
+</li>
+
+<li>
+The <a href="/pkg/net/url/"><code>net/url</code></a> package's
+<a href="/pkg/net/url/#Parse"><code>Parse</code></a> is now stricter and more spec-compliant regarding the parsing
+of host names.
+For example, spaces in the host name are no longer accepted.
+</li>
+
+<li>
+Also in the <a href="/pkg/net/url/"><code>net/url</code></a> package,
+the <a href="/pkg/net/url/#Error"><code>Error</code></a> type now implements
+<a href="/pkg/net/#Error"><code>net.Error</code></a>.
+</li>
+
+<li>
+The <a href="/pkg/os/"><code>os</code></a> package's
+<a href="/pkg/os/#IsExist"><code>IsExist</code></a>,
+<a href="/pkg/os/#IsNotExist"><code>IsNotExist</code></a>,
+and
+<a href="/pkg/os/#IsPermission"><code>IsPermission</code></a>
+now return correct results when inquiring about an
+<a href="/pkg/os/#SyscallError"><code>SyscallError</code></a>.
+</li>
+
+<li>
+On Unix-like systems, when a write
+to <a href="/pkg/os/#pkg-variables"><code>os.Stdout</code>
+or <code>os.Stderr</code></a> (more precisely, an <code>os.File</code>
+opened for file descriptor 1 or 2) fails due to a broken pipe error,
+the program will raise a <code>SIGPIPE</code> signal.
+By default this will cause the program to exit; this may be changed by
+calling the
+<a href="/pkg/os/signal"><code>os/signal</code></a>
+<a href="/pkg/os/signal/#Notify"><code>Notify</code></a> function
+for <code>syscall.SIGPIPE</code>.
+A write to a broken pipe on a file descriptor other 1 or 2 will simply
+return <code>syscall.EPIPE</code> (possibly wrapped in
+<a href="/pkg/os#PathError"><code>os.PathError</code></a>
+and/or <a href="/pkg/os#SyscallError"><code>os.SyscallError</code></a>)
+to the caller.
+The old behavior of raising an uncatchable <code>SIGPIPE</code> signal
+after 10 consecutive writes to a broken pipe no longer occurs.
+</li>
+
+<li>
+In the <a href="/pkg/os/exec/"><code>os/exec</code></a> package,
+<a href="/pkg/os/exec/#Cmd"><code>Cmd</code></a>'s
+<a href="/pkg/os/exec/#Cmd.Output"><code>Output</code></a> method continues to return an
+<a href="/pkg/os/exec/#ExitError"><code>ExitError</code></a> when a command exits with an unsuccessful status.
+If standard error would otherwise have been discarded,
+the returned <code>ExitError</code> now holds a prefix and suffix
+(currently 32 kB) of the failed command's standard error output,
+for debugging or for inclusion in error messages.
+The <code>ExitError</code>'s
+<a href="/pkg/os/exec/#ExitError.String"><code>String</code></a>
+method does not show the captured standard error;
+programs must retrieve it from the data structure
+separately.
+</li>
+
+<li>
+On Windows, the <a href="/pkg/path/filepath/"><code>path/filepath</code></a> package's
+<a href="/pkg/path/filepath/#Join"><code>Join</code></a> function now correctly handles the case when the base is a relative drive path.
+For example, <code>Join(`c:`,</code> <code>`a`)</code> now
+returns <code>`c:a`</code> instead of <code>`c:\a`</code> as in past releases.
+This may affect code that expects the incorrect result.
+</li>
+
+<li>
+In the <a href="/pkg/regexp/"><code>regexp</code></a> package,
+the
+<a href="/pkg/regexp/#Regexp"><code>Regexp</code></a> type has always been safe for use by
+concurrent goroutines.
+It uses a <a href="/pkg/sync/#Mutex"><code>sync.Mutex</code></a> to protect
+a cache of scratch spaces used during regular expression searches.
+Some high-concurrency servers using the same <code>Regexp</code> from many goroutines
+have seen degraded performance due to contention on that mutex.
+To help such servers, <code>Regexp</code> now has a
+<a href="/pkg/regexp/#Regexp.Copy"><code>Copy</code></a> method,
+which makes a copy of a <code>Regexp</code> that shares most of the structure
+of the original but has its own scratch space cache.
+Two goroutines can use different copies of a <code>Regexp</code>
+without mutex contention.
+A copy does have additional space overhead, so <code>Copy</code>
+should only be used when contention has been observed.
+</li>
+
+<li>
+The <a href="/pkg/strconv/"><code>strconv</code></a> package adds
+<a href="/pkg/strconv/#IsGraphic"><code>IsGraphic</code></a>,
+similar to <a href="/pkg/strconv/#IsPrint"><code>IsPrint</code></a>.
+It also adds
+<a href="/pkg/strconv/#QuoteToGraphic"><code>QuoteToGraphic</code></a>,
+<a href="/pkg/strconv/#QuoteRuneToGraphic"><code>QuoteRuneToGraphic</code></a>,
+<a href="/pkg/strconv/#AppendQuoteToGraphic"><code>AppendQuoteToGraphic</code></a>,
+and
+<a href="/pkg/strconv/#AppendQuoteRuneToGraphic"><code>AppendQuoteRuneToGraphic</code></a>,
+analogous to
+<a href="/pkg/strconv/#QuoteToASCII"><code>QuoteToASCII</code></a>,
+<a href="/pkg/strconv/#QuoteRuneToASCII"><code>QuoteRuneToASCII</code></a>,
+and so on.
+The <code>ASCII</code> family escapes all space characters except ASCII space (U+0020).
+In contrast, the <code>Graphic</code> family does not escape any Unicode space characters (category Zs).
+</li>
+
+<li>
+In the <a href="/pkg/testing/"><code>testing</code></a> package,
+when a test calls
+<a href="/pkg/testing/#T.Parallel">t.Parallel</a>,
+that test is paused until all non-parallel tests complete, and then
+that test continues execution with all other parallel tests.
+Go 1.6 changes the time reported for such a test:
+previously the time counted only the parallel execution,
+but now it also counts the time from the start of testing
+until the call to <code>t.Parallel</code>.
+</li>
+
+<li>
+The <a href="/pkg/text/template/"><code>text/template</code></a> package
+contains two minor changes, in addition to the <a href="#template">major changes</a>
+described above.
+First, it adds a new
+<a href="/pkg/text/template/#ExecError"><code>ExecError</code></a> type
+returned for any error during
+<a href="/pkg/text/template/#Template.Execute"><code>Execute</code></a>
+that does not originate in a <code>Write</code> to the underlying writer.
+Callers can distinguish template usage errors from I/O errors by checking for
+<code>ExecError</code>.
+Second, the
+<a href="/pkg/text/template/#Template.Funcs"><code>Funcs</code></a> method
+now checks that the names used as keys in the
+<a href="/pkg/text/template/#FuncMap"><code>FuncMap</code></a>
+are identifiers that can appear in a template function invocation.
+If not, <code>Funcs</code> panics.
+</li>
+
+<li>
+The <a href="/pkg/time/"><code>time</code></a> package's
+<a href="/pkg/time/#Parse"><code>Parse</code></a> function has always rejected any day of month larger than 31,
+such as January 32.
+In Go 1.6, <code>Parse</code> now also rejects February 29 in non-leap years,
+February 30, February 31, April 31, June 31, September 31, and November 31.
+</li>
+
+</ul>

+	"Title": "Go 1 and the Future of Go Programs",
+	"Path":  "/doc/go1compat"
+}-->
+
+<h2 id="introduction">Introduction</h2>
+<p>
+The release of Go version 1, Go 1 for short, is a major milestone
+in the development of the language. Go 1 is a stable platform for
+the growth of programs and projects written in Go.
+</p>
+
+<p>
+Go 1 defines two things: first, the specification of the language;
+and second, the specification of a set of core APIs, the "standard
+packages" of the Go library. The Go 1 release includes their
+implementation in the form of two compiler suites (gc and gccgo),
+and the core libraries themselves.
+</p>
+
+<p>
+It is intended that programs written to the Go 1 specification will
+continue to compile and run correctly, unchanged, over the lifetime
+of that specification. At some indefinite point, a Go 2 specification
+may arise, but until that time, Go programs that work today should
+continue to work even as future "point" releases of Go 1 arise (Go
+1.1, Go 1.2, etc.).
+</p>
+
+<p>
+Compatibility is at the source level. Binary compatibility for
+compiled packages is not guaranteed between releases. After a point
+release, Go source will need to be recompiled to link against the
+new release.
+</p>
+
+<p>
+The APIs may grow, acquiring new packages and features, but not in
+a way that breaks existing Go 1 code.
+</p>
+
+<h2 id="expectations">Expectations</h2>
+
+<p>
+Although we expect that the vast majority of programs will maintain
+this compatibility over time, it is impossible to guarantee that
+no future change will break any program. This document is an attempt
+to set expectations for the compatibility of Go 1 software in the
+future. There are a number of ways in which a program that compiles
+and runs today may fail to do so after a future point release. They
+are all unlikely but worth recording.
+</p>
+
+<ul>
+<li>
+Security. A security issue in the specification or implementation
+may come to light whose resolution requires breaking compatibility.
+We reserve the right to address such security issues.
+</li>
+
+<li>
+Unspecified behavior. The Go specification tries to be explicit
+about most properties of the language, but there are some aspects
+that are undefined. Programs that depend on such unspecified behavior
+may break in future releases.
+</li>
+
+<li>
+Specification errors. If it becomes necessary to address an
+inconsistency or incompleteness in the specification, resolving the
+issue could affect the meaning or legality of existing programs.
+We reserve the right to address such issues, including updating the
+implementations. Except for security issues, no incompatible changes
+to the specification would be made.
+</li>
+
+<li>
+Bugs. If a compiler or library has a bug that violates the
+specification, a program that depends on the buggy behavior may
+break if the bug is fixed. We reserve the right to fix such bugs.
+</li>
+
+<li>
+Struct literals. For the addition of features in later point
+releases, it may be necessary to add fields to exported structs in
+the API. Code that uses unkeyed struct literals (such as pkg.T{3,
+"x"}) to create values of these types would fail to compile after
+such a change. However, code that uses keyed literals (pkg.T{A:
+3, B: "x"}) will continue to compile after such a change. We will
+update such data structures in a way that allows keyed struct
+literals to remain compatible, although unkeyed literals may fail
+to compile. (There are also more intricate cases involving nested
+data structures or interfaces, but they have the same resolution.)
+We therefore recommend that composite literals whose type is defined
+in a separate package should use the keyed notation.
+</li>
+
+<li>
+Methods. As with struct fields, it may be necessary to add methods
+to types.
+Under some circumstances, such as when the type is embedded in
+a struct along with another type,
+the addition of the new method may break
+the struct by creating a conflict with an existing method of the other
+embedded type.
+We cannot protect against this rare case and do not guarantee compatibility
+should it arise.
+</li>
+
+<li>
+Dot imports. If a program imports a standard package
+using <code>import . "path"</code>, additional names defined in the
+imported package in future releases may conflict with other names
+defined in the program.  We do not recommend the use of <code>import .</code>
+outside of tests, and using it may cause a program to fail
+to compile in future releases.
+</li>
+
+<li>
+Use of package <code>unsafe</code>. Packages that import
+<a href="/pkg/unsafe/"><code>unsafe</code></a>
+may depend on internal properties of the Go implementation.
+We reserve the right to make changes to the implementation
+that may break such programs.
+</li>
+
+</ul>
+
+<p>
+Of course, for all of these possibilities, should they arise, we
+would endeavor whenever feasible to update the specification,
+compilers, or libraries without affecting existing code.
+</p>
+
+<p>
+These same considerations apply to successive point releases. For
+instance, code that runs under Go 1.2 should be compatible with Go
+1.2.1, Go 1.3, Go 1.4, etc., although not necessarily with Go 1.1
+since it may use features added only in Go 1.2
+</p>
+
+<p>
+Features added between releases, available in the source repository
+but not part of the numbered binary releases, are under active
+development. No promise of compatibility is made for software using
+such features until they have been released.
+</p>
+
+<p>
+Finally, although it is not a correctness issue, it is possible
+that the performance of a program may be affected by
+changes in the implementation of the compilers or libraries upon
+which it depends.
+No guarantee can be made about the performance of a
+given program between releases.
+</p>
+
+<p>
+Although these expectations apply to Go 1 itself, we hope similar
+considerations would be made for the development of externally
+developed software based on Go 1.
+</p>
+
+<h2 id="subrepos">Sub-repositories</h2>
+
+<p>
+Code in sub-repositories of the main go tree, such as
+<a href="//golang.org/x/net">golang.org/x/net</a>,
+may be developed under
+looser compatibility requirements. However, the sub-repositories
+will be tagged as appropriate to identify versions that are compatible
+with the Go 1 point releases.
+</p>
+
+<h2 id="operating_systems">Operating systems</h2>
+
+<p>
+It is impossible to guarantee long-term compatibility with operating
+system interfaces, which are changed by outside parties.
+The <a href="/pkg/syscall/"><code>syscall</code></a> package
+is therefore outside the purview of the guarantees made here.
+As of Go version 1.4, the <code>syscall</code> package is frozen.
+Any evolution of the system call interface must be supported elsewhere,
+such as in the
+<a href="//golang.org/x/sys">go.sys</a> subrepository.
+For details and background, see
+<a href="//golang.org/s/go1.4-syscall">this document</a>.
+</p>
+
+<h2 id="tools">Tools</h2>
+
+<p>
+Finally, the Go tool chain (compilers, linkers, build tools, and so
+on) are under active development and may change behavior. This
+means, for instance, that scripts that depend on the location and
+properties of the tools may be broken by a point release.
+</p>
+
+<p>
+These caveats aside, we believe that Go 1 will be a firm foundation
+for the development of Go and its ecosystem.
