-# Treat all files in the Go repo as binary, with no git magic updating
-# line endings. Windows users contributing to Go will need to use a
-# modern version of git and editors capable of LF line endings.

-# We'll prevent accidental CRLF line endings from entering the repo
-# via the git-review gofmt checks.

-# Contributing to Go
-
-Go is an open source project.
-
-It is the work of hundreds of contributors. We appreciate your help!
-
-
-## Filing issues
-
-When filing an issue, make sure to answer these five questions:
-
-1. What version of Go are you using (`go version`)?
-2. What operating system and processor architecture are you using?
-3. What did you do?
-4. What did you expect to see?
-5. What did you see instead?
-
-General questions should go to the [golang-nuts mailing list](https://groups.google.com/group/golang-nuts) instead of the issue tracker.
-The gophers there will answer or ask you to file an issue if you've tripped over a bug.
-
-## Contributing code
-
-Please read the [Contribution Guidelines](https://golang.org/doc/contribute.html)
-before sending patches.
-
-**We do not accept GitHub pull requests**
-(we use [Gerrit](https://code.google.com/p/gerrit/) instead for code review).
-
-Unless otherwise noted, the Go source files are distributed under
-the BSD-style license found in the LICENSE file.

+This is the source code repository for the Go programming language.  
+
+For documentation about how to install and use Go,
+visit http://golang.org/ or load doc/install.html in your web browser.
+
+After installing Go, you can view a nicely formatted
+doc/install.html by running godoc --http=:6060
+and then visiting http://localhost:6060/doc/install.html.
+
+Unless otherwise noted, the Go source files are distributed
+under the BSD-style license found in the LICENSE file.
+

+
+Binary Distribution Notes
+
+If you have just untarred a binary Go distribution, you need to set
+the environment variable $GOROOT to the full path of the go
+directory (the one containing this README).  You can omit the
+variable if you unpack it into /usr/local/go, or if you rebuild
+from sources by running all.bash (see doc/install.html).
+You should also add the Go binary directory $GOROOT/bin
+to your shell's path.
+
+For example, if you extracted the tar file into $HOME/go, you might
+put the following in your .profile:
+
+    export GOROOT=$HOME/go
+    export PATH=$PATH:$GOROOT/bin
+
+See doc/install.html for more details.

-## Binary Distribution Notes
-
-If you have just untarred a binary Go distribution, you need to set
-the environment variable $GOROOT to the full path of the go
-directory (the one containing this file).  You can omit the
-variable if you unpack it into /usr/local/go, or if you rebuild
-from sources by running all.bash (see doc/install-source.html).
-You should also add the Go binary directory $GOROOT/bin
-to your shell's path.
-
-For example, if you extracted the tar file into $HOME/go, you might
-put the following in your .profile:
-
-	export GOROOT=$HOME/go
-	export PATH=$PATH:$GOROOT/bin
-
-See https://golang.org/doc/install or doc/install.html for more details.

+<!--{
+"Title": "C? Go? Cgo!",
+"Template": true
+}-->
+
+<p>
+Cgo lets Go packages call C code. Given a Go source file written with some
+special features, cgo outputs Go and C files that can be combined into a
+single Go package.
+</p>
+
+<p>
+To lead with an example, here's a Go package that provides two functions -
+<code>Random</code> and <code>Seed</code> - that wrap C's <code>random</code>
+and <code>srandom</code> functions.
+</p>
+
+{{code "/doc/progs/cgo1.go" `/package rand/` `/END/`}}
+
+<p>
+Let's look at what's happening here, starting with the import statement.
+</p>
+
+<p>
+The <code>rand</code> package imports <code>"C"</code>, but you'll find there's
+no such package in the standard Go library. That's because <code>C</code> is a
+"pseudo-package", a special name interpreted by cgo as a reference to C's
+name space.
+</p>
+
+<p>
+The <code>rand</code> package contains four references to the <code>C</code>
+package: the calls to <code>C.random</code> and <code>C.srandom</code>, the
+conversion <code>C.uint(i)</code>, and the <code>import</code> statement.
+</p>
+
+<p>
+The <code>Random</code> function calls the standard C library's <code>random</code>
+function and returns the result.  In C, <code>random</code> returns a value of the
+C type <code>long</code>, which cgo represents as the type <code>C.long</code>.
+It must be converted to a Go type before it can be used by Go code outside this
+package, using an ordinary Go type conversion:
+</p>
+
+{{code "/doc/progs/cgo1.go" `/func Random/` `/STOP/`}}
+
+<p>
+Here's an equivalent function that uses a temporary variable to illustrate
+the type conversion more explicitly:
+</p>
+
+{{code "/doc/progs/cgo2.go" `/func Random/` `/STOP/`}}
+
+<p>
+The <code>Seed</code> function does the reverse, in a way. It takes a
+regular Go <code>int</code>, converts it to the C <code>unsigned int</code>
+type, and passes it to the C function <code>srandom</code>.
+</p>
+
+{{code "/doc/progs/cgo1.go" `/func Seed/` `/END/`}}
+
+<p>
+Note that cgo knows the <code>unsigned int</code> type as <code>C.uint</code>;
+see the <a href="/cmd/cgo">cgo documentation</a> for a complete list of
+these numeric type names.
+</p>
+
+<p>
+The one detail of this example we haven't examined yet is the comment
+above the <code>import</code> statement.
+</p>
+
+{{code "/doc/progs/cgo1.go" `/\/\*/` `/STOP/`}}
+
+<p>
+Cgo recognizes this comment.  Any lines starting
+with <code>#cgo</code>
+followed
+by a space character are removed; these become directives for cgo.
+The remaining lines are used as a header when compiling the C parts of
+the package.  In this case those lines are just a
+single <code>#include</code>
+statement, but they can be almost any C code.  The <code>#cgo</code>
+directives are
+used to provide flags for the compiler and linker when building the C
+parts of the package.
+</p>
+
+<p>
+There is a limitation: if your program uses any <code>//export</code>
+directives, then the C code in the comment may only include declarations
+(<code>extern int f();</code>), not definitions (<code>int f() {
+return 1; }</code>).  You can use <code>//export</code> directives to
+make Go functions accessible to C code.
+</p>
+
+<p>
+The <code>#cgo</code> and <code>//export</code> directives are
+documented in
+the <a href="/cmd/cgo/">cgo documentation</a>.
+</p>
+
+<p>
+<b>Strings and things</b>
+</p>
+
+<p>
+Unlike Go, C doesn't have an explicit string type. Strings in C are
+represented by a zero-terminated array of chars.
+</p>
+
+<p>
+Conversion between Go and C strings is done with the
+<code>C.CString</code>, <code>C.GoString</code>, and
+<code>C.GoStringN</code> functions. These conversions make a copy of the
+string data.
+</p>
+
+<p>
+This next example implements a <code>Print</code> function that writes a
+string to standard output using C's <code>fputs</code> function from the
+<code>stdio</code> library:
+</p>
+
+{{code "/doc/progs/cgo3.go" `/package print/` `/END/`}}
+
+<p>
+Memory allocations made by C code are not known to Go's memory manager.
+When you create a C string with <code>C.CString</code> (or any C memory
+allocation) you must remember to free the memory when you're done with it
+by calling <code>C.free</code>.
+</p>
+
+<p>
+The call to <code>C.CString</code> returns a pointer to the start of the
+char array, so before the function exits we convert it to an
+<a href="/pkg/unsafe/#Pointer"><code>unsafe.Pointer</code></a> and release
+the memory allocation with <code>C.free</code>. A common idiom in cgo programs
+is to <a href="/doc/articles/defer_panic_recover.html"><code>defer</code></a>
+the free immediately after allocating (especially when the code that follows
+is more complex than a single function call), as in this rewrite of
+<code>Print</code>:
+</p>
+
+{{code "/doc/progs/cgo4.go" `/func Print/` `/END/`}}
+
+<p>
+<b>Building cgo packages</b>
+</p>
+
+<p>
+To build cgo packages, just use <a href="/cmd/go/#hdr-Compile_packages_and_dependencies">"
+<code>go build</code>"</a> or
+<a href="/cmd/go/#hdr-Compile_and_install_packages_and_dependencies">"<code>go install</code>
+"</a> as usual. The go tool recognizes the special <code>"C"</code> import and automatically
+uses cgo for those files.
+</p>
+
+<p>
+<b>More cgo resources</b>
+</p>
+
+<p>
+The <a href="/cmd/cgo/">cgo command</a> documentation has more detail about
+the C pseudo-package and the build process. The <a href="/misc/cgo/">cgo examples</a>
+in the Go tree demonstrate more advanced concepts.
+</p>
+
+<p>
+For a simple, idiomatic example of a cgo-based package, see Russ Cox's <a
+href="http://code.google.com/p/gosqlite/source/browse/sqlite/sqlite.go">gosqlite</a>.
+Also, the <a href="http://code.google.com/p/go-wiki/wiki/Projects">Go Community Wiki</a>
+lists many packages, some of which use cgo.
+</p>
+
+<p>
+Finally, if you're curious as to how all this works internally, take a look
+at the introductory comment of the runtime package's <a href="/src/pkg/runtime/cgocall.c">cgocall.c</a>.

+<!--{
+"Title": "Go Concurrency Patterns: Timing out, moving on",
+"Template": true
+}-->
+
+<p>
+Concurrent programming has its own idioms. A good example is timeouts. Although
+Go's channels do not support them directly, they are easy to implement. Say we
+want to receive from the channel <code>ch</code>, but want to wait at most one
+second for the value to arrive. We would start by creating a signalling channel
+and launching a goroutine that sleeps before sending on the channel:
+</p>
+
+{{code "/doc/progs/timeout1.go" `/timeout :=/` `/STOP/`}}
+
+<p>
+We can then use a <code>select</code> statement to receive from either
+<code>ch</code> or <code>timeout</code>. If nothing arrives on <code>ch</code>
+after one second, the timeout case is selected and the attempt to read from
+<code>ch</code> is abandoned.
+</p>
+
+{{code "/doc/progs/timeout1.go" `/select {/` `/STOP/`}}
+
+<p>
+The <code>timeout</code> channel is buffered with space for 1 value, allowing
+the timeout goroutine to send to the channel and then exit. The goroutine
+doesn't know (or care) whether the value is received. This means the goroutine
+won't hang around forever if the <code>ch</code> receive happens before the
+timeout is reached. The <code>timeout</code> channel will eventually be
+deallocated by the garbage collector.
+</p>
+
+<p>
+(In this example we used <code>time.Sleep</code> to demonstrate the mechanics
+of goroutines and channels. In real programs you should use <code>
+<a href="/pkg/time/#After">time.After</a></code>, a function that returns
+a channel and sends on that channel after the specified duration.)
+</p>
+
+<p>
+Let's look at another variation of this pattern. In this example we have a
+program that reads from multiple replicated databases simultaneously. The
+program needs only one of the answers, and it should accept the answer that
+arrives first.
+</p>
+
+<p>
+The function <code>Query</code> takes a slice of database connections and a
+<code>query</code> string. It queries each of the databases in parallel and
+returns the first response it receives:
+</p>
+
+{{code "/doc/progs/timeout2.go" `/func Query/` `/STOP/`}}
+
+<p>
+In this example, the closure does a non-blocking send, which it achieves by
+using the send operation in <code>select</code> statement with a
+<code>default</code> case. If the send cannot go through immediately the
+default case will be selected. Making the send non-blocking guarantees that
+none of the goroutines launched in the loop will hang around. However, if the
+result arrives before the main function has made it to the receive, the send
+could fail since no one is ready.
+</p>
+
+<p>
+This problem is a textbook example of what is known as a
+<a href="https://en.wikipedia.org/wiki/Race_condition">race condition</a>, but
+the fix is trivial. We just make sure to buffer the channel <code>ch</code> (by
+adding the buffer length as the second argument to <a href="/pkg/builtin/#make">make</a>),
+guaranteeing that the first send has a place to put the value. This ensures the
+send will always succeed, and the first value to arrive will be retrieved
+regardless of the order of execution.
+</p>
+
+<p>
+These two examples demonstrate the simplicity with which Go can express complex
+interactions between goroutines.

+has the go statement to run code in a separate goroutine.  Here I'd like to
+discuss some of the less common ones: defer, panic, and recover.
+</p>
+ 
+<p>
+A <b>defer statement</b> pushes a function call onto a list. The list of saved
+calls is executed after the surrounding function returns. Defer is commonly
+used to simplify functions that perform various clean-up actions.
+</p>
+ 
+<p>
+For example, let's look at a function that opens two files and copies the
+contents of one file to the other:
+</p>
+ 
+{{code "/doc/progs/defer.go" `/func CopyFile/` `/STOP/`}}
+
+<p>
+This works, but there is a bug. If the call to os.Create fails, the
+function will return without closing the source file. This can be easily
+remedied by putting a call to src.Close before the second return statement,
+but if the function were more complex the problem might not be so easily
+noticed and resolved. By introducing defer statements we can ensure that the
+files are always closed:
+</p>
+ 
+{{code "/doc/progs/defer2.go" `/func CopyFile/` `/STOP/`}}
+
+<p>
+Defer statements allow us to think about closing each file right after opening
+it, guaranteeing that, regardless of the number of return statements in the
+function, the files <i>will</i> be closed.
+</p>
+ 
+<p>
+The behavior of defer statements is straightforward and predictable. There are
+three simple rules:
+</p>
+ 
+<p>
+1. <i>A deferred function's arguments are evaluated when the defer statement is
+evaluated.</i> 
+</p>
+ 
+<p>
+In this example, the expression "i" is evaluated when the Println call is
+deferred. The deferred call will print "0" after the function returns.
+</p>
+ 
+{{code "/doc/progs/defer.go" `/func a/` `/STOP/`}}
+
+<p>
+2. <i>Deferred function calls are executed in Last In First Out order
+</i>after<i> the surrounding function returns.</i> 
+</p>
+ 
+<p>
+This function prints "3210":
+</p>
+
+{{code "/doc/progs/defer.go" `/func b/` `/STOP/`}}
+ 
+<p>
+3. <i>Deferred functions may read and assign to the returning function's named
+return values.</i> 
+</p>
+ 
+<p>
+In this example, a deferred function increments the return value i <i>after</i>
+the surrounding function returns. Thus, this function returns 2:
+</p>
+
+{{code "/doc/progs/defer.go" `/func c/` `/STOP/`}}
+ 
+<p>
+This is convenient for modifying the error return value of a function; we will
+see an example of this shortly.
+</p>
+ 
+<p>
+<b>Panic</b> is a built-in function that stops the ordinary flow of control and
+begins <i>panicking</i>. When the function F calls panic, execution of F stops,
+any deferred functions in F are executed normally, and then F returns to its
+caller. To the caller, F then behaves like a call to panic. The process
+continues up the stack until all functions in the current goroutine have
+returned, at which point the program crashes. Panics can be initiated by
+invoking panic directly. They can also be caused by runtime errors, such as
+out-of-bounds array accesses.
+</p>
+ 
+<p>
+<b>Recover</b> is a built-in function that regains control of a panicking
+goroutine. Recover is only useful inside deferred functions. During normal
+execution, a call to recover will return nil and have no other effect. If the
+current goroutine is panicking, a call to recover will capture the value given
+to panic and resume normal execution.
+</p>
+ 
+<p>
+Here's an example program that demonstrates the mechanics of panic and defer:
+</p>
+
+{{code "/doc/progs/defer2.go" `/package main/` `/STOP/`}}
+ 
+<p>
+The function g takes the int i, and panics if i is greater than 3, or else it
+calls itself with the argument i+1. The function f defers a function that calls
+recover and prints the recovered value (if it is non-nil). Try to picture what
+the output of this program might be before reading on.
+</p>
+ 
+<p>
+The program will output:
+</p>
+ 
+<pre>Calling g.
+Printing in g 0
+Printing in g 1
+Printing in g 2
+Printing in g 3
+Panicking!
+Defer in g 3
+Defer in g 2
+Defer in g 1
+Defer in g 0
+Recovered in f 4
+Returned normally from f.</pre> 
+
+<p>
+If we remove the deferred function from f the panic is not recovered and
+reaches the top of the goroutine's call stack, terminating the program. This
+modified program will output:
+</p>
+ 
+<pre>Calling g.
+Printing in g 0
+Printing in g 1
+Printing in g 2
+Printing in g 3
+Panicking!
+Defer in g 3
+Defer in g 2
+Defer in g 1
+Defer in g 0
+panic: 4
+ 
+panic PC=0x2a9cd8
+[stack trace omitted]</pre> 
+
+<p>
+For a real-world example of <b>panic</b> and <b>recover</b>, see the
+<a href="/pkg/encoding/json/">json package</a> from the Go standard library.
+It decodes JSON-encoded data with a set of recursive functions.
+When malformed JSON is encountered, the parser calls panic to unwind the
+stack to the top-level function call, which recovers from the panic and returns
+an appropriate error value (see the 'error' and 'unmarshal' methods of
+the decodeState type in
+<a href="/src/pkg/encoding/json/decode.go">decode.go</a>).
+</p>
+
+<p>
+The convention in the Go libraries is that even when a package uses panic
+internally, its external API still presents explicit error return values.
+</p>
+ 
+<p>
+Other uses of <b>defer</b> (beyond the file.Close example given earlier)
+include releasing a mutex:
+</p>
+
+<pre>mu.Lock()
+defer mu.Unlock()</pre> 
+
+<p>
+printing a footer:
+</p>
+ 
+<pre>printHeader()
+defer printFooter()</pre> 
+
+<p>
+and more.
+</p>
+ 
+<p>
+In summary, the defer statement (with or without panic and recover) provides an
+unusual and powerful mechanism for control flow.  It can be used to model a
+number of features implemented by special-purpose structures in other
+programming languages. Try it out.

+<p>
+If you have written any Go code you have probably encountered the built-in
+<code>error</code> type. Go code uses <code>error</code> values to
+indicate an abnormal state. For example, the <code>os.Open</code> function
+returns a non-nil <code>error</code> value when it fails to open a file.
+</p>
+
+{{code "/doc/progs/error.go" `/func Open/`}}
+
+<p>
+The following code uses <code>os.Open</code> to open a file. If an error
+occurs it calls <code>log.Fatal</code> to print the error message and stop.
+</p>
+
+{{code "/doc/progs/error.go" `/func openFile/` `/STOP/`}}
+
+<p>
+You can get a lot done in Go knowing just this about the <code>error</code>
+type, but in this article we'll take a closer look at <code>error</code> and
+discuss some good practices for error handling in Go.
+</p>
+
+<p>
+<b>The error type</b>
+</p>
+
+<p>
+The <code>error</code> type is an interface type. An <code>error</code>
+variable represents any value that can describe itself as a string. Here is the
+interface's declaration:
+</p>
+
+<pre>type error interface {
+    Error() string
+}</pre>
+
+<p>
+The <code>error</code> type, as with all built in types, is
+<a href="/doc/go_spec.html#Predeclared_identifiers">predeclared</a> in the
+<a href="/doc/go_spec.html#Blocks">universe block</a>.
+</p>
+
+<p>
+The most commonly-used <code>error</code> implementation is the
+<a href="/pkg/errors/">errors</a> package's unexported <code>errorString</code> type.
+</p>
+
+{{code "/doc/progs/error.go" `/errorString/` `/STOP/`}}
+
+<p>
+You can construct one of these values with the <code>errors.New</code>
+function. It takes a string that it converts to an <code>errors.errorString</code>
+and returns as an <code>error</code> value.
+</p>
+
+{{code "/doc/progs/error.go" `/New/` `/STOP/`}}
+
+<p>
+Here's how you might use <code>errors.New</code>:
+</p>
+
+{{code "/doc/progs/error.go" `/func Sqrt/` `/STOP/`}}
+
+<p>
+A caller passing a negative argument to <code>Sqrt</code> receives a non-nil
+<code>error</code> value (whose concrete representation is an
+<code>errors.errorString</code> value). The caller can access the error string
+("math: square root of...") by calling the <code>error</code>'s
+<code>Error</code> method, or by just printing it:
+</p>
+
+{{code "/doc/progs/error.go" `/func printErr/` `/STOP/`}}
+
+<p>
+The <a href="/pkg/fmt/">fmt</a> package formats an <code>error</code> value
+by calling its <code>Error() string</code> method.
+</p>
+
+<p>
+It is the error implementation's responsibility to summarize the context.
+The error returned by <code>os.Open</code> formats as "open /etc/passwd:
+permission denied," not just "permission denied."  The error returned by our
+<code>Sqrt</code> is missing information about the invalid argument.
+</p>
+
+<p>
+To add that information, a useful function is the <code>fmt</code> package's
+<code>Errorf</code>. It formats a string according to <code>Printf</code>'s
+rules and returns it as an <code>error</code> created by
+<code>errors.New</code>.
+</p>
+
+{{code "/doc/progs/error.go" `/fmtError/` `/STOP/`}}
+
+<p>
+In many cases <code>fmt.Errorf</code> is good enough, but since
+<code>error</code> is an interface, you can use arbitrary data structures as
+error values, to allow callers to inspect the details of the error.
+</p>
+
+<p>
+For instance, our hypothetical callers might want to recover the invalid
+argument passed to <code>Sqrt</code>. We can enable that by defining a new
+error implementation instead of using <code>errors.errorString</code>:
+</p>
+
+{{code "/doc/progs/error.go" `/type NegativeSqrtError/` `/STOP/`}}
+
+<p>
+A sophisticated caller can then use a
+<a href="/doc/go_spec.html#Type_assertions">type assertion</a> to check for a
+<code>NegativeSqrtError</code> and handle it specially, while callers that just
+pass the error to <code>fmt.Println</code> or <code>log.Fatal</code> will see
+no change in behavior.
+</p>
+
+<p>
+As another example, the <a href="/pkg/encoding/json/">json</a> package specifies a
+<code>SyntaxError</code> type that the <code>json.Decode</code> function
+returns when it encounters a syntax error parsing a JSON blob.
+</p>
+
+{{code "/doc/progs/error.go" `/type SyntaxError/` `/STOP/`}}
+
+<p>
+The <code>Offset</code> field isn't even shown in the default formatting of the
+error, but callers can use it to add file and line information to their error
+messages:
+</p>
+
+{{code "/doc/progs/error.go" `/func decodeError/` `/STOP/`}}
+
+<p>
+(This is a slightly simplified version of some
+<a href="http://golang.org/s/camjsondecode">actual code</a>
+from the <a href="http://camlistore.org">Camlistore</a> project.)
+</p>
+
+<p>
+The <code>error</code> interface requires only a <code>Error</code> method;
+specific error implementations might have additional methods. For instance, the
+<a href="/pkg/net/">net</a> package returns errors of type
+<code>error</code>, following the usual convention, but some of the error
+implementations have additional methods defined by the <code>net.Error</code>
+interface:
+</p>
+
+<pre>package net
+
+type Error interface {
+    error
+    Timeout() bool   // Is the error a timeout?
+    Temporary() bool // Is the error temporary?
+}</pre>
+
+<p>
+Client code can test for a <code>net.Error</code> with a type assertion and
+then distinguish transient network errors from permanent ones. For instance, a
+web crawler might sleep and retry when it encounters a temporary error and give
+up otherwise.
+</p>
+
+{{code "/doc/progs/error.go" `/func netError/` `/STOP/`}}
+
+<p>
+<b>Simplifying repetitive error handling</b>
+</p>
+
+<p>
+In Go, error handling is important. The language's design and conventions
+encourage you to explicitly check for errors where they occur (as distinct from
+the convention in other languages of throwing exceptions and sometimes catching
+them). In some cases this makes Go code verbose, but fortunately there are some
+techniques you can use to minimize repetitive error handling.
+</p>
+
+<p>
+Consider an <a href="http://code.google.com/appengine/docs/go/">App Engine</a>
+application with an HTTP handler that retrieves a record from the datastore and
+formats it with a template.
+</p>
+
+{{code "/doc/progs/error2.go" `/func init/` `/STOP/`}}
+
+<p>
+This function handles errors returned by the <code>datastore.Get</code>
+function and <code>viewTemplate</code>'s <code>Execute</code> method. In both
+cases, it presents a simple error message to the user with the HTTP status code
+500 ("Internal Server Error"). This looks like a manageable amount of code, but
+add some more HTTP handlers and you quickly end up with many copies of
+identical error handling code.
+</p>
+
+<p>
+To reduce the repetition we can define our own HTTP <code>appHandler</code>
+type that includes an <code>error</code> return value:
+</p>
+
+{{code "/doc/progs/error3.go" `/type appHandler/`}}
+
+<p>
+Then we can change our <code>viewRecord</code> function to return errors:
+</p>
+
+{{code "/doc/progs/error3.go" `/func viewRecord/` `/STOP/`}}
+
+<p>
+This is simpler than the original version, but the <a
+href="/pkg/net/http/">http</a> package doesn't understand functions that return
+<code>error</code>.
+To fix this we can implement the <code>http.Handler</code> interface's
+<code>ServeHTTP</code> method on <code>appHandler</code>:
+</p>
+
+{{code "/doc/progs/error3.go" `/ServeHTTP/` `/STOP/`}}
+
+<p>
+The <code>ServeHTTP</code> method calls the <code>appHandler</code> function
+and displays the returned error (if any) to the user.  Notice that the method's
+receiver, <code>fn</code>, is a function. (Go can do that!) The method invokes
+the function by calling the receiver in the expression <code>fn(w, r)</code>.
+</p>
+
+<p>
+Now when registering <code>viewRecord</code> with the http package we use the
+<code>Handle</code> function (instead of <code>HandleFunc</code>) as
+<code>appHandler</code> is an <code>http.Handler</code> (not an
+<code>http.HandlerFunc</code>). 
+</p>
+
+{{code "/doc/progs/error3.go" `/func init/` `/STOP/`}}
+
+<p>
+With this basic error handling infrastructure in place, we can make it more
+user friendly. Rather than just displaying the error string, it would be better
+to give the user a simple error message with an appropriate HTTP status code,
+while logging the full error to the App Engine developer console for debugging
+purposes.
+</p>
+
+<p>
+To do this we create an <code>appError</code> struct containing an
+<code>error</code> and some other fields:
+</p>
+
+{{code "/doc/progs/error4.go" `/type appError/` `/STOP/`}}
+
+<p>
+Next we modify the appHandler type to return <code>*appError</code> values:
+</p>
+
+{{code "/doc/progs/error4.go" `/type appHandler/`}}
+
+<p>
+(It's usually a mistake to pass back the concrete type of an error rather than
+<code>error</code>,
+for reasons discussed in <a href="/doc/go_faq.html#nil_error">the Go FAQ</a>,
+but it's the right thing to do here because <code>ServeHTTP</code> is the only
+place that sees the value and uses its contents.)
+</p>
+
+<p>
+And make <code>appHandler</code>'s <code>ServeHTTP</code> method display the
+<code>appError</code>'s <code>Message</code> to the user with the correct HTTP
+status <code>Code</code> and log the full <code>Error</code> to the developer
+console:
+</p>
+
+{{code "/doc/progs/error4.go" `/ServeHTTP/` `/STOP/`}}
+
+<p>
+Finally, we update <code>viewRecord</code> to the new function signature and
+have it return more context when it encounters an error: 
+</p>
+
+{{code "/doc/progs/error4.go" `/func viewRecord/` `/STOP/`}}
+
+<p>
+This version of <code>viewRecord</code> is the same length as the original, but
+now each of those lines has specific meaning and we are providing a friendlier
+user experience.
+</p>
+
+<p>
+It doesn't end there; we can further improve the error handling in our
+application. Some ideas:
+</p>
+
+<ul>
+<li>give the error handler a pretty HTML template,
+<li>make debugging easier by writing the stack trace to the HTTP response when
+the user is an administrator,
+<li>write a constructor function for <code>appError</code> that stores the
+stack trace for easier debugging, 
+<li>recover from panics inside the <code>appHandler</code>, logging the error
+to the console as "Critical," while telling the user "a serious error
+has occurred." This is a nice touch to avoid exposing the user to inscrutable
+error messages caused by programming errors.
+See the <a href="defer_panic_recover.html">Defer, Panic, and Recover</a>
+article for more details.
+</ul>
+
+<p>
+<b>Conclusion</b>
+</p>
+
+<p>
+Proper error handling is an essential requirement of good software. By
+employing the techniques described in this post you should be able to write
+more reliable and succinct Go code.

+<p>
+To transmit a data structure across a network or to store it in a file, it must
+be encoded and then decoded again. There are many encodings available, of
+course: <a href="http://www.json.org/">JSON</a>,
+<a href="http://www.w3.org/XML/">XML</a>, Google's
+<a href="http://code.google.com/p/protobuf">protocol buffers</a>, and more.
+And now there's another, provided by Go's <a href="/pkg/encoding/gob/">gob</a>
+package.
+</p>
+
+<p>
+Why define a new encoding? It's a lot of work and redundant at that. Why not
+just use one of the existing formats? Well, for one thing, we do! Go has
+<a href="/pkg/">packages</a> supporting all the encodings just mentioned (the
+<a href="http://code.google.com/p/goprotobuf">protocol buffer package</a> is in
+a separate repository but it's one of the most frequently downloaded). And for
+many purposes, including communicating with tools and systems written in other
+languages, they're the right choice.
+</p>
+
+<p>
+But for a Go-specific environment, such as communicating between two servers
+written in Go, there's an opportunity to build something much easier to use and
+possibly more efficient.
+</p>
+
+<p>
+Gobs work with the language in a way that an externally-defined,
+language-independent encoding cannot. At the same time, there are lessons to be
+learned from the existing systems.
+</p>
+
+<p>
+<b>Goals</b>
+</p>
+
+<p>
+The gob package was designed with a number of goals in mind.
+</p>
+
+<p>
+First, and most obvious, it had to be very easy to use. First, because Go has
+reflection, there is no need for a separate interface definition language or
+"protocol compiler". The data structure itself is all the package should need
+to figure out how to encode and decode it. On the other hand, this approach
+means that gobs will never work as well with other languages, but that's OK:
+gobs are unashamedly Go-centric.
+</p>
+
+<p>
+Efficiency is also important. Textual representations, exemplified by XML and
+JSON, are too slow to put at the center of an efficient communications network.
+A binary encoding is necessary.
+</p>
+
+<p>
+Gob streams must be self-describing. Each gob stream, read from the beginning,
+contains sufficient information that the entire stream can be parsed by an
+agent that knows nothing a priori about its contents. This property means that
+you will always be able to decode a gob stream stored in a file, even long
+after you've forgotten what data it represents.
+</p>
+
+<p>
+There were also some things to learn from our experiences with Google protocol
+buffers.
+</p>
+
+<p>
+<b>Protocol buffer misfeatures</b>
+</p>
+
+<p>
+Protocol buffers had a major effect on the design of gobs, but have three
+features that were deliberately avoided. (Leaving aside the property that
+protocol buffers aren't self-describing: if you don't know the data definition
+used to encode a protocol buffer, you might not be able to parse it.)
+</p>
+
+<p>
+First, protocol buffers only work on the data type we call a struct in Go. You
+can't encode an integer or array at the top level, only a struct with fields
+inside it. That seems a pointless restriction, at least in Go. If all you want
+to send is an array of integers, why should you have to put it into a
+struct first?
+</p>
+
+<p>
+Next, a protocol buffer definition may specify that fields <code>T.x</code> and
+<code>T.y</code> are required to be present whenever a value of type
+<code>T</code> is encoded or decoded.  Although such required fields may seem
+like a good idea, they are costly to implement because the codec must maintain a
+separate data structure while encoding and decoding, to be able to report when
+required fields are missing.  They're also a maintenance problem. Over time, one
+may want to modify the data definition to remove a required field, but that may
+cause existing clients of the data to crash. It's better not to have them in the
+encoding at all.  (Protocol buffers also have optional fields. But if we don't
+have required fields, all fields are optional and that's that. There will be
+more to say about optional fields a little later.)
+</p>
+
+<p>
+The third protocol buffer misfeature is default values. If a protocol buffer
+omits the value for a "defaulted" field, then the decoded structure behaves as
+if the field were set to that value. This idea works nicely when you have
+getter and setter methods to control access to the field, but is harder to
+handle cleanly when the container is just a plain idiomatic struct. Required
+fields are also tricky to implement: where does one define the default values,
+what types do they have (is text UTF-8? uninterpreted bytes? how many bits in a
+float?) and despite the apparent simplicity, there were a number of
+complications in their design and implementation for protocol buffers. We
+decided to leave them out of gobs and fall back to Go's trivial but effective
+defaulting rule: unless you set something otherwise, it has the "zero value"
+for that type - and it doesn't need to be transmitted.
+</p>
+
+<p>
+So gobs end up looking like a sort of generalized, simplified protocol buffer.
+How do they work?
+</p>
+
+<p>
+<b>Values</b>
+</p>
+
+<p>
+The encoded gob data isn't about <code>int8</code>s and <code>uint16</code>s.
+Instead, somewhat analogous to constants in Go, its integer values are abstract,
+sizeless numbers, either signed or unsigned. When you encode an
+<code>int8</code>, its value is transmitted as an unsized, variable-length
+integer. When you encode an <code>int64</code>, its value is also transmitted as
+an unsized, variable-length integer. (Signed and unsigned are treated
+distinctly, but the same unsized-ness applies to unsigned values too.) If both
+have the value 7, the bits sent on the wire will be identical. When the receiver
+decodes that value, it puts it into the receiver's variable, which may be of
+arbitrary integer type. Thus an encoder may send a 7 that came from an
+<code>int8</code>, but the receiver may store it in an <code>int64</code>. This
+is fine: the value is an integer and as a long as it fits, everything works. (If
+it doesn't fit, an error results.) This decoupling from the size of the variable
+gives some flexibility to the encoding: we can expand the type of the integer
+variable as the software evolves, but still be able to decode old data.
+</p>
+
+<p>
+This flexibility also applies to pointers. Before transmission, all pointers are
+flattened. Values of type <code>int8</code>, <code>*int8</code>,
+<code>**int8</code>, <code>****int8</code>, etc. are all transmitted as an
+integer value, which may then be stored in <code>int</code> of any size, or
+<code>*int</code>, or <code>******int</code>, etc. Again, this allows for
+flexibility.
+</p>
+
+<p>
+Flexibility also happens because, when decoding a struct, only those fields
+that are sent by the encoder are stored in the destination. Given the value
+</p>
+
+{{code "/doc/progs/gobs1.go" `/type T/` `/STOP/`}}
+
+<p>
+the encoding of <code>t</code> sends only the 7 and 8. Because it's zero, the
+value of <code>Y</code> isn't even sent; there's no need to send a zero value.
+</p>
+
+<p>
+The receiver could instead decode the value into this structure:
+</p>
+
+{{code "/doc/progs/gobs1.go" `/type U/` `/STOP/`}}
+
+<p>
+and acquire a value of <code>u</code> with only <code>X</code> set (to the
+address of an <code>int8</code> variable set to 7); the <code>Z</code> field is
+ignored - where would you put it? When decoding structs, fields are matched by
+name and compatible type, and only fields that exist in both are affected. This
+simple approach finesses the "optional field" problem: as the type
+<code>T</code> evolves by adding fields, out of date receivers will still
+function with the part of the type they recognize. Thus gobs provide the
+important result of optional fields - extensibility - without any additional
+mechanism or notation.
+</p>
+
+<p>
+From integers we can build all the other types: bytes, strings, arrays, slices,
+maps, even floats. Floating-point values are represented by their IEEE 754
+floating-point bit pattern, stored as an integer, which works fine as long as
+you know their type, which we always do. By the way, that integer is sent in
+byte-reversed order because common values of floating-point numbers, such as
+small integers, have a lot of zeros at the low end that we can avoid
+transmitting.
+</p>
+
+<p>
+One nice feature of gobs that Go makes possible is that they allow you to define
+your own encoding by having your type satisfy the
+<a href="/pkg/encoding/gob/#GobEncoder">GobEncoder</a> and
+<a href="/pkg/encoding/gob/#GobDecoder">GobDecoder</a> interfaces, in a manner
+analogous to the <a href="/pkg/encoding/json/">JSON</a> package's
+<a href="/pkg/encoding/json/#Marshaler">Marshaler</a> and
+<a href="/pkg/encoding/json/#Unmarshaler">Unmarshaler</a> and also to the
+<a href="/pkg/fmt/#Stringer">Stringer</a> interface from
+<a href="/pkg/fmt/">package fmt</a>. This facility makes it possible to
+represent special features, enforce constraints, or hide secrets when you
+transmit data. See the <a href="/pkg/encoding/gob/">documentation</a> for
+details.
+</p>
+
+<p>
+<b>Types on the wire</b>
+</p>
+
+<p>
+The first time you send a given type, the gob package includes in the data
+stream a description of that type. In fact, what happens is that the encoder is
+used to encode, in the standard gob encoding format, an internal struct that
+describes the type and gives it a unique number. (Basic types, plus the layout
+of the type description structure, are predefined by the software for
+bootstrapping.) After the type is described, it can be referenced by its type
+number.
+</p>
+
+<p>
+Thus when we send our first type <code>T</code>, the gob encoder sends a
+description of <code>T</code> and tags it with a type number, say 127. All
+values, including the first, are then prefixed by that number, so a stream of
+<code>T</code> values looks like:
+</p>
+
+<pre>
+("define type id" 127, definition of type T)(127, T value)(127, T value), ...
+</pre>
+
+<p>
+These type numbers make it possible to describe recursive types and send values
+of those types. Thus gobs can encode types such as trees:
+</p>
+
+{{code "/doc/progs/gobs1.go" `/type Node/` `/STOP/`}}
+
+<p>
+(It's an exercise for the reader to discover how the zero-defaulting rule makes
+this work, even though gobs don't represent pointers.)
+</p>
+
+<p>
+With the type information, a gob stream is fully self-describing except for the
+set of bootstrap types, which is a well-defined starting point.
+</p>
+
+<p>
+<b>Compiling a machine</b>
+</p>
+
+<p>
+The first time you encode a value of a given type, the gob package builds a
+little interpreted machine specific to that data type. It uses reflection on
+the type to construct that machine, but once the machine is built it does not
+depend on reflection. The machine uses package unsafe and some trickery to
+convert the data into the encoded bytes at high speed. It could use reflection
+and avoid unsafe, but would be significantly slower. (A similar high-speed
+approach is taken by the protocol buffer support for Go, whose design was
+influenced by the implementation of gobs.) Subsequent values of the same type
+use the already-compiled machine, so they can be encoded right away.
+</p>
+
+<p>
+Decoding is similar but harder. When you decode a value, the gob package holds
+a byte slice representing a value of a given encoder-defined type to decode,
+plus a Go value into which to decode it. The gob package builds a machine for
+that pair: the gob type sent on the wire crossed with the Go type provided for
+decoding. Once that decoding machine is built, though, it's again a
+reflectionless engine that uses unsafe methods to get maximum speed.
+</p>
+
+<p>
+<b>Use</b>
+</p>
+
+<p>
+There's a lot going on under the hood, but the result is an efficient,
+easy-to-use encoding system for transmitting data. Here's a complete example
+showing differing encoded and decoded types. Note how easy it is to send and
+receive values; all you need to do is present values and variables to the
+<a href="/pkg/encoding/gob/">gob package</a> and it does all the work.
+</p>
+
+{{code "/doc/progs/gobs2.go" `/package main/` `$`}}
+
+<p>
+You can compile and run this example code in the
+<a href="http://play.golang.org/p/_-OJV-rwMq">Go Playground</a>.
+</p>
+
+<p>
+The <a href="/pkg/net/rpc/">rpc package</a> builds on gobs to turn this
+encode/decode automation into transport for method calls across the network.
+That's a subject for another article.
+</p>
+
+<p>
+<b>Details</b>

+The <a href="/pkg/encoding/gob/">gob package documentation</a>, especially the
+file <a href="/src/pkg/encoding/gob/doc.go">doc.go</a>, expands on many of the

+implementation, that's a good place to start.

+<!--{
+"Title": "Godoc: documenting Go code",
+"Template": true
+}-->
+
+<p>
+The Go project takes documentation seriously. Documentation is a huge part of
+making software accessible and maintainable. Of course it must be well-written
+and accurate, but it also must be easy to write and to maintain. Ideally, it
+should be coupled to the code itself so the documentation evolves along with the
+code. The easier it is for programmers to produce good documentation, the better
+for everyone.
+</p>
+
+<p>
+To that end, we have developed the <a href="/cmd/godoc/">godoc</a> documentation
+tool. This article describes godoc's approach to documentation, and explains how
+you can use our conventions and tools to write good documentation for your own
+projects.
+</p>
+
+<p>
+Godoc parses Go source code - including comments - and produces documentation as
+HTML or plain text. The end result is documentation tightly coupled with the
+code it documents. For example, through godoc's web interface you can navigate
+from a function's <a href="/pkg/strings/#HasPrefix">documentation</a> to its
+<a href="/src/pkg/strings/strings.go?#L312">implementation</a> with one click.
+</p>
+
+<p>
+Godoc is conceptually related to Python's
+<a href="http://www.python.org/dev/peps/pep-0257/">Docstring</a> and Java's
+<a href="http://www.oracle.com/technetwork/java/javase/documentation/index-jsp-135444.html">Javadoc</a>,
+but its design is simpler. The comments read by godoc are not language
+constructs (as with Docstring) nor must they have their own machine-readable
+syntax (as with Javadoc). Godoc comments are just good comments, the sort you
+would want to read even if godoc didn't exist.
+</p>
+
+<p>
+The convention is simple: to document a type, variable, constant, function, or
+even a package, write a regular comment directly preceding its declaration, with
+no intervening blank line. Godoc will then present that comment as text
+alongside the item it documents. For example, this is the documentation for the
+<code>fmt</code> package's <a href="/pkg/fmt/#Fprint"><code>Fprint</code></a>
+function:
+</p>
+
+{{code "/src/pkg/fmt/print.go" `/Fprint formats using the default/` `/func Fprint/`}}
+
+<p>
+Notice this comment is a complete sentence that begins with the name of the
+element it describes. This important convention allows us to generate
+documentation in a variety of formats, from plain text to HTML to UNIX man
+pages, and makes it read better when tools truncate it for brevity, such as when
+they extract the first line or sentence.
+</p>
+
+<p>
+Comments on package declarations should provide general package documentation.
+These comments can be short, like the <a href="/pkg/sort/"><code>sort</code></a>
+package's brief description:
+</p>
+
+{{code "/src/pkg/sort/sort.go" `/Package sort provides/` `/package sort/`}}
+
+<p>
+They can also be detailed like the <a href="/pkg/encoding/gob/"><code>gob</code></a>
+package's overview. That package uses another convention for packages
+that need large amounts of introductory documentation: the package comment is
+placed in its own file, <a href="/src/pkg/encoding/gob/doc.go">doc.go</a>, which
+contains only those comments and a package clause.
+</p>
+
+<p>
+When writing package comments of any size, keep in mind that their first
+sentence will appear in godoc's <a href="/pkg/">package list</a>.
+</p>
+
+<p>
+Comments that are not adjacent to a top-level declaration are omitted from
+godoc's output, with one notable exception. Top-level comments that begin with
+the word <code>"BUG(who)"</code> are recognized as known bugs, and included in
+the "Bugs" section of the package documentation. The "who" part should be the
+user name of someone who could provide more information. For example, this is a
+known issue from the <a href="/pkg/sync/atomic/#pkg-note-BUG"><code>sync/atomic</code></a> package:
+</p>
+
+<pre>
+// BUG(rsc): On x86-32, the 64-bit functions use instructions
+// unavailable before the Pentium MMX. On both ARM and x86-32, it is the
+// caller's responsibility to arrange for 64-bit alignment of 64-bit
+// words accessed atomically.
+</pre>
+
+<p>
+Godoc treats executable commands in the same way. It looks for a comment on
+package main, which is sometimes put in a separate file called <code>doc.go</code>.
+For example, see the
+<a href="/cmd/godoc/">godoc documentation</a> and its corresponding
+<a href="/src/cmd/godoc/doc.go">doc.go</a> file.
+</p>
+
+<p>
+There are a few formatting rules that Godoc uses when converting comments to
+HTML:
+</p>
+
+<ul>
+<li>
+Subsequent lines of text are considered part of the same paragraph; you must
+leave a blank line to separate paragraphs.
+</li>
+<li>
+Pre-formatted text must be indented relative to the surrounding comment text
+(see gob's <a href="/src/pkg/encoding/gob/doc.go">doc.go</a> for an example).
+</li>
+<li>
+URLs will be converted to HTML links; no special markup is necessary.
+</li>
+</ul>
+
+<p>
+Note that none of these rules requires you to do anything out of the ordinary.
+</p>
+
+<p>
+In fact, the best thing about godoc's minimal approach is how easy it is to use.
+As a result, a lot of Go code, including all of the standard library, already
+follows the conventions.
+</p>
+
+<p>
+Your own code can present good documentation just by having comments as
+described above. Any Go packages installed inside <code>$GOROOT/src/pkg</code>
+and any <code>GOPATH</code> work spaces will already be accessible via godoc's
+command-line and HTTP interfaces, and you can specify additional paths for
+indexing via the <code>-path</code> flag or just by running <code>"godoc ."</code>
+in the source directory. See the <a href="/cmd/godoc/">godoc documentation</a>
+for more details.
+</p>
+
+<p>
+Godoc recognizes example functions written according to the
+<a href="/pkg/testing/#pkg-overview"><code>testing</code></a> package's naming
+conventions and presents them appropriately.

+<!--{
+"Title": "Go's Declaration Syntax"
+}-->
+
+<p>
+Newcomers to Go wonder why the declaration syntax is different from the
+tradition established in the C family. In this post we'll compare the
+two approaches and explain why Go's declarations look as they do.
+</p>
+
+<p>
+<b>C syntax</b>
+</p>
+
+<p>
+First, let's talk about C syntax. C took an unusual and clever approach
+to declaration syntax. Instead of describing the types with special
+syntax, one writes an expression involving the item being declared, and
+states what type that expression will have. Thus
+</p>
+
+<pre>
+int x;
+</pre>
+
+<p>
+declares x to be an int: the expression 'x' will have type int. In
+general, to figure out how to write the type of a new variable, write an
+expression involving that variable that evaluates to a basic type, then
+put the basic type on the left and the expression on the right.
+</p>
+
+<p>
+Thus, the declarations
+</p>
+
+<pre>
+int *p;
+int a[3];
+</pre>
+
+<p>
+state that p is a pointer to int because '*p' has type int, and that a
+is an array of ints because a[3] (ignoring the particular index value,
+which is punned to be the size of the array) has type int.
+</p>
+
+<p>
+What about functions? Originally, C's function declarations wrote the
+types of the arguments outside the parens, like this:
+</p>
+
+<pre>
+int main(argc, argv)
+    int argc;
+    char *argv[];
+{ /* ... */ }
+</pre>
+
+<p>
+Again, we see that main is a function because the expression main(argc,
+argv) returns an int. In modern notation we'd write
+</p>
+
+<pre>
+int main(int argc, char *argv[]) { /* ... */ }
+</pre>
+
+<p>
+but the basic structure is the same.
+</p>
+
+<p>
+This is a clever syntactic idea that works well for simple types but can
+get confusing fast. The famous example is declaring a function pointer.
+Follow the rules and you get this:
+</p>
+
+<pre>
+int (*fp)(int a, int b);
+</pre>
+
+<p>
+Here, fp is a pointer to a function because if you write the expression
+(*fp)(a, b) you'll call a function that returns int. What if one of fp's
+arguments is itself a function?
+</p>
+
+<pre>
+int (*fp)(int (*ff)(int x, int y), int b)
+</pre>
+
+<p>
+That's starting to get hard to read.
+</p>
+
+<p>
+Of course, we can leave out the name of the parameters when we declare a
+function, so main can be declared
+</p>
+
+<pre>
+int main(int, char *[])
+</pre>
+
+<p>
+Recall that argv is declared like this,
+</p>
+
+<pre>
+char *argv[]
+</pre>
+
+<p>
+so you drop the name from the <em>middle</em> of its declaration to construct
+its type. It's not obvious, though, that you declare something of type
+char *[] by putting its name in the middle.
+</p>
+
+<p>
+And look what happens to fp's declaration if you don't name the
+parameters:
+</p>
+
+<pre>
+int (*fp)(int (*)(int, int), int)
+</pre>
+
+<p>
+Not only is it not obvious where to put the name inside
+</p>
+
+<pre>
+int (*)(int, int)
+</pre>
+
+<p>
+it's not exactly clear that it's a function pointer declaration at all.
+And what if the return type is a function pointer?
+</p>
+
+<pre>
+int (*(*fp)(int (*)(int, int), int))(int, int)
+</pre>
+
+<p>
+It's hard even to see that this declaration is about fp.
+</p>
+
+<p>
+You can construct more elaborate examples but these should illustrate
+some of the difficulties that C's declaration syntax can introduce.
+</p>
+
+<p>
+There's one more point that needs to be made, though. Because type and
+declaration syntax are the same, it can be difficult to parse
+expressions with types in the middle. This is why, for instance, C casts
+always parenthesize the type, as in
+</p>
+
+<pre>
+(int)M_PI
+</pre>
+
+<p>
+<b>Go syntax</b>
+</p>
+
+<p>
+Languages outside the C family usually use a distinct type syntax in
+declarations. Although it's a separate point, the name usually comes
+first, often followed by a colon. Thus our examples above become
+something like (in a fictional but illustrative language)
+</p>
+
+<pre>
+x: int
+p: pointer to int
+a: array[3] of int
+</pre>
+
+<p>
+These declarations are clear, if verbose - you just read them left to
+right. Go takes its cue from here, but in the interests of brevity it
+drops the colon and removes some of the keywords:
+</p>
+
+<pre>
+x int
+p *int
+a [3]int
+</pre>
+
+<p>
+There is no direct correspondence between the look of [3]int and how to
+use a in an expression. (We'll come back to pointers in the next
+section.) You gain clarity at the cost of a separate syntax.
+</p>
+
+<p>
+Now consider functions. Let's transcribe the declaration for main, even
+though the main function in Go takes no arguments:
+</p>
+
+<pre>
+func main(argc int, argv *[]byte) int
+</pre>
+
+<p>
+Superficially that's not much different from C, but it reads well from
+left to right:
+</p>
+
+<p>
+<em>function main takes an int and a pointer to a slice of bytes and returns an int.</em>
+</p>
+
+<p>
+Drop the parameter names and it's just as clear - they're always first
+so there's no confusion.
+</p>
+
+<pre>
+func main(int, *[]byte) int
+</pre>
+
+<p>
+One value of this left-to-right style is how well it works as the types
+become more complex. Here's a declaration of a function variable
+(analogous to a function pointer in C):
+</p>
+
+<pre>
+f func(func(int,int) int, int) int
+</pre>
+
+<p>
+Or if f returns a function:
+</p>
+
+<pre>
+f func(func(int,int) int, int) func(int, int) int
+</pre>
+
+<p>
+It still reads clearly, from left to right, and it's always obvious
+which name is being declared - the name comes first.
+</p>
+
+<p>
+The distinction between type and expression syntax makes it easy to
+write and invoke closures in Go:
+</p>
+
+<pre>
+sum := func(a, b int) int { return a+b } (3, 4)
+</pre>
+
+<p>
+<b>Pointers</b>
+</p>
+
+<p>
+Pointers are the exception that proves the rule. Notice that in arrays
+and slices, for instance, Go's type syntax puts the brackets on the left
+of the type but the expression syntax puts them on the right of the
+expression:
+</p>
+
+<pre>
+var a []int
+x = a[1]
+</pre>
+
+<p>
+For familiarity, Go's pointers use the * notation from C, but we could
+not bring ourselves to make a similar reversal for pointer types. Thus
+pointers work like this
+</p>
+
+<pre>
+var p *int
+x = *p
+</pre>
+
+<p>
+We couldn't say
+</p>
+
+<pre>
+var p *int
+x = p*
+</pre>
+
+<p>
+because that postfix * would conflate with multiplication. We could have
+used the Pascal ^, for example:
+</p>
+
+<pre>
+var p ^int
+x = p^
+</pre>
+
+<p>
+and perhaps we should have (and chosen another operator for xor),
+because the prefix asterisk on both types and expressions complicates
+things in a number of ways. For instance, although one can write
+</p>
+
+<pre>
+[]int("hi")
+</pre>
+
+<p>
+as a conversion, one must parenthesize the type if it starts with a *:
+</p>
+
+<pre>
+(*int)(nil)
+</pre>
+
+<p>
+Had we been willing to give up * as pointer syntax, those parentheses
+would be unnecessary.
+</p>
+
+<p>
+So Go's pointer syntax is tied to the familiar C form, but those ties
+mean that we cannot break completely from using parentheses to
+disambiguate types and expressions in the grammar.
+</p>
+
+<p>
+Overall, though, we believe Go's type syntax is easier to understand
+than C's, especially when things get complicated.
+</p>
+
+<p>
+<b>Notes</b>
+</p>
+
+<p>
+Go's declarations read left to right. It's been pointed out that C's
+read in a spiral! See <a href="http://c-faq.com/decl/spiral.anderson.html">
+The "Clockwise/Spiral Rule"</a> by David Anderson.

+<p>
+<a href="/pkg/image/draw/">Package image/draw</a> defines
+only one operation: drawing a source image onto a destination
+image, through an optional mask image. This one operation is
+surprisingly versatile and can perform a number of common image
+manipulation tasks elegantly and efficiently.  
+</p>
+
+<p>
+Composition is performed pixel by pixel in the style of the Plan 9
+graphics library and the X Render extension. The model is based on
+the classic "Compositing Digital Images" paper by Porter and Duff,
+with an additional mask parameter: <code>dst = (src IN mask) OP dst</code>.
+For a fully opaque mask, this reduces to the original Porter-Duff
+formula: <code>dst = src OP dst</code>. In Go, a nil mask image is equivalent
+to an infinitely sized, fully opaque mask image.
+</p>
+
+<p>
+The Porter-Duff paper presented
+<a href="http://www.w3.org/TR/SVGCompositing/examples/compop-porterduff-examples.png">12 different composition operators</a>,
+but with an explicit mask, only 2 of these are needed in practice:
+source-over-destination and source. In Go, these operators are
+represented by the <code>Over</code> and <code>Src</code> constants. The <code>Over</code> operator
+performs the natural layering of a source image over a destination
+image: the change to the destination image is smaller where the
+source (after masking) is more transparent (that is, has lower
+alpha). The <code>Src</code> operator merely copies the source (after masking)
+with no regard for the destination image's original content. For
+fully opaque source and mask images, the two operators produce the
+same output, but the <code>Src</code> operator is usually faster.
+</p>
+
+<p><b>Geometric Alignment</b></p>
+
+<p>  
+Composition requires associating destination pixels with source and
+mask pixels. Obviously, this requires destination, source and mask
+images, and a composition operator, but it also requires specifying
+what rectangle of each image to use. Not every drawing should write
+to the entire destination: when updating an animating image, it is
+more efficient to only draw the parts of the image that have
+changed. Not every drawing should read from the entire source: when
+using a sprite that combines many small images into one large one,
+only a part of the image is needed. Not every drawing should read
+from the entire mask: a mask image that collects a font's glyphs is
+similar to a sprite. Thus, drawing also needs to know three
+rectangles, one for each image. Since each rectangle has the same
+width and height, it suffices to pass a destination rectangle `r`
+and two points <code>sp</code> and <code>mp</code>: the source rectangle is equal to <code>r</code>
+translated so that <code>r.Min</code> in the destination image aligns with 
+<code>sp</code> in the source image, and similarly for <code>mp</code>. The effective
+rectangle is also clipped to each image's bounds in their
+respective co-ordinate space.

+The <a href="/pkg/image/draw/#DrawMask"><code>DrawMask</code></a>
+function takes seven arguments, but an explicit mask and mask-point
+are usually unnecessary, so the
+<a href="/pkg/image/draw/#Draw"><code>Draw</code></a> function takes five:
+</p>
+
+<pre>
+// Draw calls DrawMask with a nil mask.
+func Draw(dst Image, r image.Rectangle, src image.Image, sp image.Point, op Op)
+func DrawMask(dst Image, r image.Rectangle, src image.Image, sp image.Point,
+	mask image.Image, mp image.Point, op Op)
+</pre>
+
+<p>
+The destination image must be mutable, so the image/draw package
+defines a <a href="/pkg/image/draw/#Image"><code>draw.Image</code></a>
+interface which has a <code>Set</code> method.

+<p><b>Filling a Rectangle</b></p>
+
+<p>
+To fill a rectangle with a solid color, use an <code>image.Uniform</code>
+source. The <code>Uniform</code> type re-interprets a <code>Color</code> as a
+practically infinite-sized <code>Image</code> of that color. For those
+familiar with the design of Plan 9's draw library, there is no need
+for an explicit "repeat bit" in Go's slice-based image types; the
+concept is subsumed by <code>Uniform</code>.

+image's color model cannot represent transparency), use

+To copy from a rectangle <code>sr</code> in the source image to a rectangle
+starting at a point <code>dp</code> in the destination, convert the source
+rectangle into the destination image's co-ordinate space:

+<p><b>Scrolling an Image</b></p>
+

+Scrolling an image is just copying an image to itself, with

+<p><b>Performance</b></p>
+
+<p>
+The image/draw package implementation demonstrates how to provide
+an image manipulation function that is both general purpose, yet
+efficient for common cases. The <code>DrawMask</code> function takes arguments
+of interface types, but immediately makes type assertions that its
+arguments are of specific struct types, corresponding to common
+operations like drawing one <code>image.RGBA</code> image onto another, or
+drawing an <code>image.Alpha</code> mask (such as a font glyph) onto an
+<code>image.RGBA</code> image. If a type assertion succeeds, that type
+information is used to run a specialized implementation of the
+general algorithm. If the assertions fail, the fallback code path
+uses the generic <code>At</code> and <code>Set</code> methods. The fast-paths are purely
+a performance optimization; the resultant destination image is the
+same either way. In practice, only a small number of special cases
+are necessary to support typical applications.

+The <a href="/pkg/image/">image</a> and
+<a href="/pkg/image/color/">image/color</a> packages define a number of types:
+<code>color.Color</code> and <code>color.Model</code> describe colors,
+<code>image.Point</code> and <code>image.Rectangle</code> describe basic 2-D
+geometry, and <code>image.Image</code> brings the two concepts together to
+represent a rectangular grid of colors. A
+<a href="/doc/articles/image_draw.html">separate article</a> covers image
+composition with the <a href="/pkg/image/draw/">image/draw</a> package.
+</p>
+
+<p>
+<b>Colors and Color Models</b>
+</p>
+
+<p>
+<a href="/pkg/image/color/#Color">Color</a> is an interface that defines the minimal
+method set of any type that can be considered a color: one that can be converted
+to red, green, blue and alpha values. The conversion may be lossy, such as
+converting from CMYK or YCbCr color spaces.
+</p>
+
+{{code "/src/pkg/image/color/color.go" `/type Color interface/` `/^}/`}}
+
+<p>
+There are three important subtleties about the return values. First, the red,
+green and blue are alpha-premultiplied: a fully saturated red that is also 25%
+transparent is represented by RGBA returning a 75% r. Second, the channels have
+a 16-bit effective range: 100% red is represented by RGBA returning an r of
+65535, not 255, so that converting from CMYK or YCbCr is not as lossy. Third,
+the type returned is <code>uint32</code>, even though the maximum value is 65535, to
+guarantee that multiplying two values together won't overflow. Such
+multiplications occur when blending two colors according to an alpha mask from a
+third color, in the style of
+<a href="https://en.wikipedia.org/wiki/Alpha_compositing">Porter and Duff's</a>
+classic algebra:
+</p>
+
+<pre>
+dstr, dstg, dstb, dsta := dst.RGBA()
+srcr, srcg, srcb, srca := src.RGBA()
+_, _, _, m := mask.RGBA()
+const M = 1&lt;&lt;16 - 1
+// The resultant red value is a blend of dstr and srcr, and ranges in [0, M].
+// The calculation for green, blue and alpha is similar.
+dstr = (dstr*(M-m) + srcr*m) / M
+</pre>
+
+<p>
+The last line of that code snippet would have been more complicated if we worked
+with non-alpha-premultiplied colors, which is why <code>Color</code> uses
+alpha-premultiplied values.
+</p>
+
+<p>
+The image/color package also defines a number of concrete types that implement
+the <code>Color</code> interface. For example,
+<a href="/pkg/image/color/#RGBA"><code>RGBA</code></a> is a struct that represents
+the classic "8 bits per channel" color.
+</p>
+
+{{code "/src/pkg/image/color/color.go" `/type RGBA struct/` `/^}/`}}
+
+<p>
+Note that the <code>R</code> field of an <code>RGBA</code> is an 8-bit
+alpha-premultiplied color in the range [0, 255]. <code>RGBA</code> satisfies the
+<code>Color</code> interface by multiplying that value by 0x101 to generate a
+16-bit alpha-premultiplied color in the range [0, 65535]. Similarly, the
+<a href="/pkg/image/color/#NRGBA"><code>NRGBA</code></a> struct type represents
+an 8-bit non-alpha-premultiplied color, as used by the PNG image format. When
+manipulating an <code>NRGBA</code>'s fields directly, the values are
+non-alpha-premultiplied, but when calling the <code>RGBA</code> method, the
+return values are alpha-premultiplied.
+</p>
+
+<p>
+A <a href="/pkg/image/color/#Model"><code>Model</code></a> is simply
+something that can convert <code>Color</code>s to other <code>Color</code>s, possibly lossily. For
+example, the <code>GrayModel</code> can convert any <code>Color</code> to a
+desaturated <a href="/pkg/image/color/#Gray"><code>Gray</code></a>. A
+<code>Palette</code> can convert any <code>Color</code> to one from a
+limited palette.
+</p>
+
+{{code "/src/pkg/image/color/color.go" `/type Model interface/` `/^}/`}}
+
+{{code "/src/pkg/image/color/color.go" `/type Palette \[\]Color/`}}
+
+<p>
+<b>Points and Rectangles</b>
+</p>
+
+<p>
+A <a href="/pkg/image/#Point"><code>Point</code></a> is an (x, y) co-ordinate
+on the integer grid, with axes increasing right and down. It is neither a pixel
+nor a grid square. A <code>Point</code> has no intrinsic width, height or
+color, but the visualizations below use a small colored square.
+</p>
+
+{{code "/src/pkg/image/geom.go" `/type Point struct/` `/^}/`}}
+
+<p>
+<img src="image-package-01.png" width="400" height="300">
+</p>
+
+{{code "/doc/progs/image_package1.go" `/p := image.Point/`}}
+
+<p>
+A <a href="/pkg/image/#Rectangle"><code>Rectangle</code></a> is an axis-aligned
+rectangle on the integer grid, defined by its top-left and bottom-right
+<code>Point</code>.  A <code>Rectangle</code> also has no intrinsic color, but
+the visualizations below outline rectangles with a thin colored line, and call
+out their <code>Min</code> and <code>Max</code> <code>Point</code>s.
+</p>
+
+{{code "/src/pkg/image/geom.go" `/type Rectangle struct/` `/^}/`}}
+
+<p>
+For convenience, <code>image.Rect(x0, y0, x1, y1)</code> is equivalent to
+<code>image.Rectangle{image.Point{x0, y0}, image.Point{x1, y1}}</code>, but is
+much easier to type.
+</p>
+
+<p>
+A <code>Rectangle</code> is inclusive at the top-left and exclusive at the
+bottom-right. For a <code>Point p</code> and a <code>Rectangle r</code>,
+<code>p.In(r)</code> if and only if
+<code>r.Min.X &lt;= p.X &amp;&amp; p.X &lt; r.Max.X</code>, and similarly for <code>Y</code>. This is analogous to how
+a slice <code>s[i0:i1]</code> is inclusive at the low end and exclusive at the
+high end. (Unlike arrays and slices, a <code>Rectangle</code> often has a
+non-zero origin.)
+</p>
+
+<p>
+<img src="image-package-02.png" width="400" height="300">
+</p>
+
+{{code "/doc/progs/image_package2.go" `/r := image.Rect/` `/fmt.Println/`}}
+
+<p>
+Adding a <code>Point</code> to a <code>Rectangle</code> translates the
+<code>Rectangle</code>. Points and Rectangles are not restricted to be in the
+bottom-right quadrant.
+</p>
+
+<p>
+<img src="image-package-03.png" width="400" height="300">
+</p>
+
+{{code "/doc/progs/image_package3.go" `/r := image.Rect/` `/fmt.Println/`}}
+
+<p>
+Intersecting two Rectangles yields another Rectangle, which may be empty.
+</p>
+
+<p>
+<img src="image-package-04.png" width="400" height="300">
+</p>
+
+{{code "/doc/progs/image_package4.go" `/r := image.Rect/` `/fmt.Printf/`}}
+
+<p>
+Points and Rectangles are passed and returned by value. A function that takes a
+<code>Rectangle</code> argument will be as efficient as a function that takes
+two <code>Point</code> arguments, or four <code>int</code> arguments.
+</p>
+
+<p>
+<b>Images</b>
+</p>
+
+<p>
+An <a href="/pkg/image/#Image">Image</a> maps every grid square in a
+<code>Rectangle</code> to a <code>Color</code> from a <code>Model</code>.
+"The pixel at (x, y)" refers to the color of the grid square defined by the
+points (x, y), (x+1, y), (x+1, y+1) and (x, y+1).
+</p>
+
+{{code "/src/pkg/image/image.go" `/type Image interface/` `/^}/`}}
+
+<p>
+A common mistake is assuming that an <code>Image</code>'s bounds start at (0,
+0). For example, an animated GIF contains a sequence of Images, and each
+<code>Image</code> after the first typically only holds pixel data for the area
+that changed, and that area doesn't necessarily start at (0, 0). The correct
+way to iterate over an <code>Image</code> m's pixels looks like:
+</p>
+
+<pre>
+b := m.Bounds()
+for y := b.Min.Y; y &lt; b.Max.Y; y++ {
+	for x := b.Min.X; x &lt; b.Max.X; x++ {
+		doStuffWith(m.At(x, y))
+	}
+}
+</pre>
+
+<p>
+<code>Image</code> implementations do not have to be based on an in-memory
+slice of pixel data. For example, a
+<a href="/pkg/image/#Uniform"><code>Uniform</code></a> is an
+<code>Image</code> of enormous bounds and uniform color, whose in-memory
+representation is simply that color.
+</p>
+
+{{code "/src/pkg/image/names.go" `/type Uniform struct/` `/^}/`}}
+
+<p>
+Typically, though, programs will want an image based on a slice. Struct types
+like <a href="/pkg/image/#RGBA"><code>RGBA</code></a> and
+<a href="/pkg/image/#Gray"><code>Gray</code></a> (which other packages refer
+to as <code>image.RGBA</code> and <code>image.Gray</code>) hold slices of pixel
+data and implement the <code>Image</code> interface.
+</p>
+
+{{code "/src/pkg/image/image.go" `/type RGBA struct/` `/^}/`}}
+
+<p>
+These types also provide a <code>Set(x, y int, c color.Color)</code> method
+that allows modifying the image one pixel at a time.
+</p>
+
+{{code "/doc/progs/image_package5.go" `/m := image.New/` `/m.Set/`}}
+
+<p>
+If you're reading or writing a lot of pixel data, it can be more efficient, but
+more complicated, to access these struct type's <code>Pix</code> field directly.
+</p>
+
+<p>
+The slice-based <code>Image</code> implementations also provide a
+<code>SubImage</code> method, which returns an <code>Image</code> backed by the
+same array. Modifying the pixels of a sub-image will affect the pixels of the
+original image, analogous to how modifying the contents of a sub-slice
+<code>s[i0:i1]</code> will affect the contents of the original slice
+<code>s</code>.
+</p>
+
+<img src="image-package-05.png" width="400" height="300">
+
+{{code "/doc/progs/image_package6.go" `/m0 := image.New/` `/fmt.Println\(m0.Stride/`}}
+
+<p>
+For low-level code that works on an image's <code>Pix</code> field, be aware
+that ranging over <code>Pix</code> can affect pixels outside an image's bounds.
+In the example above, the pixels covered by <code>m1.Pix</code> are shaded in
+blue. Higher-level code, such as the <code>At</code> and <code>Set</code>
+methods or the <a href="/pkg/image/draw/">image/draw package</a>, will clip
+their operations to the image's bounds.
+</p>
+
+<p>
+<b>Image Formats</b>
+</p>
+
+<p>
+The standard package library supports a number of common image formats, such as
+GIF, JPEG and PNG. If you know the format of a source image file, you can
+decode from an <a href="/pkg/io/#Reader"><code>io.Reader</code></a> directly.
+</p>
+
+<pre>
+import (
+	"image/jpeg"
+	"image/png"
+	"io"
+)
+
+// convertJPEGToPNG converts from JPEG to PNG.
+func convertJPEGToPNG(w io.Writer, r io.Reader) error {
+	img, err := jpeg.Decode(r)
+	if err != nil {
+		return err
+	}
+	return png.Encode(w, img)
+}
+</pre>
+
+<p>
+If you have image data of unknown format, the
+<a href="/pkg/image/#Decode"><code>image.Decode</code></a> function can detect
+the format. The set of recognized formats is constructed at run time and is not
+limited to those in the standard package library. An image format package
+typically registers its format in an init function, and the main package will
+"underscore import" such a package solely for the side effect of format
+registration.
+</p>
+
+<pre>
+import (
+	"image"
+	"image/png"
+	"io"
+
+	_ "code.google.com/p/vp8-go/webp"
+	_ "image/jpeg"
+)
+
+// convertToPNG converts from any recognized format to PNG.
+func convertToPNG(w io.Writer, r io.Reader) error {
+	img, _, err := image.Decode(r)
+	if err != nil {
+		return err
+	}
+	return png.Encode(w, img)
+}

+
+<p>
+JSON (JavaScript Object Notation) is a simple data interchange format.
+Syntactically it resembles the objects and lists of JavaScript. It is most
+commonly used for communication between web back-ends and JavaScript programs
+running in the browser, but it is used in many other places, too. Its home page,
+<a href="http://json.org">json.org</a>, provides a wonderfully clear and concise
+definition of the standard.
+</p>
+
+<p>
+With the <a href="/pkg/encoding/json/">json package</a> it's a snap to read and
+write JSON data from your Go programs.
+</p>
+
+<p>
+<b>Encoding</b>
+</p>
+
+<p>
+To encode JSON data we use the
+<a href="/pkg/encoding/json/#Marshal"><code>Marshal</code></a> function.
+</p>
+
+<pre>
+func Marshal(v interface{}) ([]byte, error)
+</pre>
+
+<p>
+Given the Go data structure, <code>Message</code>,
+</p>
+
+{{code "/doc/progs/json1.go" `/type Message/` `/STOP/`}}
+
+<p>
+and an instance of <code>Message</code>
+</p>
+
+{{code "/doc/progs/json1.go" `/m :=/`}}
+
+<p>
+we can marshal a JSON-encoded version of <code>m</code> using <code>json.Marshal</code>:
+</p>
+
+{{code "/doc/progs/json1.go" `/b, err :=/`}}
+
+<p>
+If all is well, <code>err</code> will be <code>nil</code> and <code>b</code>
+will be a <code>[]byte</code> containing this JSON data:
+</p>
+
+<pre>
+b == []byte(`{"Name":"Alice","Body":"Hello","Time":1294706395881547000}`)
+</pre>
+
+<p>
+Only data structures that can be represented as valid JSON will be encoded:
+</p>
+
+<ul>
+<li>
+JSON objects only support strings as keys; to encode a Go map type it must be
+of the form <code>map[string]T</code> (where <code>T</code> is any Go type
+supported by the json package).
+</li>
+<li>
+Channel, complex, and function types cannot be encoded.
+</li>
+<li>
+Cyclic data structures are not supported; they will cause <code>Marshal</code>
+to go into an infinite loop.
+</li>
+<li>
+Pointers will be encoded as the values they point to (or 'null' if the pointer
+is <code>nil</code>).
+</li>
+</ul>
+
+<p>
+The json package only accesses the exported fields of struct types (those that
+begin with an uppercase letter). Therefore only the exported fields of a struct
+will be present in the JSON output.
+</p>
+
+<p>
+<b>Decoding</b>
+</p>
+
+<p>
+To decode JSON data we use the
+<a href="/pkg/encoding/json/#Unmarshal"><code>Unmarshal</code></a> function.
+</p>
+
+<pre>
+func Unmarshal(data []byte, v interface{}) error
+</pre>
+
+<p>
+We must first create a place where the decoded data will be stored
+</p>
+
+{{code "/doc/progs/json1.go" `/var m Message/`}}
+
+<p>
+and call <code>json.Unmarshal</code>, passing it a <code>[]byte</code> of JSON
+data and a pointer to <code>m</code>
+</p>
+
+{{code "/doc/progs/json1.go" `/err := json.Unmarshal/`}}
+
+<p>
+If <code>b</code> contains valid JSON that fits in <code>m</code>, after the
+call <code>err</code> will be <code>nil</code> and the data from <code>b</code>
+will have been stored in the struct <code>m</code>, as if by an assignment
+like:
+</p>
+
+{{code "/doc/progs/json1.go" `/m = Message/` `/STOP/`}}
+
+<p>
+How does <code>Unmarshal</code> identify the fields in which to store the
+decoded data? For a given JSON key <code>"Foo"</code>, <code>Unmarshal</code>
+will look through the destination struct's fields to find (in order of
+preference):
+</p>
+
+<ul>
+<li>
+An exported field with a tag of <code>`json:"Foo"`</code> (see the
+<a href="/ref/spec#Struct_types">Go spec</a> for more on struct tags),
+</li>
+<li>
+An exported field named <code>"Foo"</code>, or
+</li>
+<li>
+An exported field named <code>"FOO"</code> or <code>"FoO"</code> or some other
+case-insensitive match of <code>"Foo"</code>.
+</li>
+</ul>
+
+<p>
+What happens when the structure of the JSON data doesn't exactly match the Go
+type?
+</p>
+
+{{code "/doc/progs/json1.go" `/"Food":"Pickle"/` `/STOP/`}}
+
+<p>
+<code>Unmarshal</code> will decode only the fields that it can find in the
+destination type.  In this case, only the <code>Name</code> field of m will be
+populated, and the <code>Food</code> field will be ignored. This behavior is
+particularly useful when you wish to pick only a few specific fields out of a
+large JSON blob. It also means that any unexported fields in the destination
+struct will be unaffected by <code>Unmarshal</code>.
+</p>
+
+<p>
+But what if you don't know the structure of your JSON data beforehand?
+</p>
+
+<p>
+<b>Generic JSON with <code>interface{}</code></b>
+</p>
+
+<p>
+The <code>interface{}</code> (empty interface) type describes an interface with
+zero methods.  Every Go type implements at least zero methods and therefore
+satisfies the empty interface.
+</p>
+
+<p>
+The empty interface serves as a general container type:
+</p>
+
+{{code "/doc/progs/json2.go" `/var i interface{}/` `/STOP/`}}
+
+<p>
+A type assertion accesses the underlying concrete type:
+</p>
+
+{{code "/doc/progs/json2.go" `/r := i/` `/STOP/`}}
+
+<p>
+Or, if the underlying type is unknown, a type switch determines the type:
+</p>
+
+{{code "/doc/progs/json2.go" `/switch v/` `/STOP/`}}
+
+<p>
+The json package uses <code>map[string]interface{}</code> and
+<code>[]interface{}</code> values to store arbitrary JSON objects and arrays;
+it will happily unmarshal any valid JSON blob into a plain
+<code>interface{}</code> value.  The default concrete Go types are:
+</p>
+
+<ul>
+<li>
+<code>bool</code> for JSON booleans,
+</li>
+<li>
+<code>float64</code> for JSON numbers,
+</li>
+<li>
+<code>string</code> for JSON strings, and
+</li>
+<li>
+<code>nil</code> for JSON null.
+</li>
+</ul>
+
+<p>
+<b>Decoding arbitrary data</b>
+</p>
+
+<p>
+Consider this JSON data, stored in the variable <code>b</code>:
+</p>
+
+{{code "/doc/progs/json3.go" `/b :=/`}}
+
+<p>
+Without knowing this data's structure, we can decode it into an
+<code>interface{}</code> value with <code>Unmarshal</code>:
+</p>
+
+{{code "/doc/progs/json3.go" `/var f interface/` `/STOP/`}}
+
+<p>
+At this point the Go value in <code>f</code> would be a map whose keys are
+strings and whose values are themselves stored as empty interface values:
+</p>
+
+{{code "/doc/progs/json3.go" `/f = map/` `/STOP/`}}
+
+<p>
+To access this data we can use a type assertion to access <code>f</code>'s
+underlying <code>map[string]interface{}</code>:
+</p>
+
+{{code "/doc/progs/json3.go" `/m := f/`}}
+
+<p>
+We can then iterate through the map with a range statement and use a type switch
+to access its values as their concrete types:
+</p>
+
+{{code "/doc/progs/json3.go" `/for k, v/` `/STOP/`}}
+
+<p>
+In this way you can work with unknown JSON data while still enjoying the
+benefits of type safety.
+</p>
+
+<p>
+<b>Reference Types</b>
+</p>
+
+<p>
+Let's define a Go type to contain the data from the previous example:
+</p>
+
+{{code "/doc/progs/json4.go" `/type FamilyMember/` `/STOP/`}}
+
+{{code "/doc/progs/json4.go" `/var m FamilyMember/` `/STOP/`}}
+
+<p>
+Unmarshaling that data into a <code>FamilyMember</code> value works as
+expected, but if we look closely we can see a remarkable thing has happened.
+With the var statement we allocated a <code>FamilyMember</code> struct, and
+then provided a pointer to that value to <code>Unmarshal</code>, but at that
+time the <code>Parents</code> field was a <code>nil</code> slice value. To
+populate the <code>Parents</code> field, <code>Unmarshal</code> allocated a new
+slice behind the scenes. This is typical of how <code>Unmarshal</code> works
+with the supported reference types (pointers, slices, and maps).
+</p>
+
+<p>
+Consider unmarshaling into this data structure:
+</p>
+
+<pre>
+type Foo struct {
+    Bar *Bar
+}
+</pre>
+
+<p>
+If there were a <code>Bar</code> field in the JSON object,
+<code>Unmarshal</code> would allocate a new <code>Bar</code> and populate it.
+If not, <code>Bar</code> would be left as a <code>nil</code> pointer.
+</p>
+
+<p>
+From this a useful pattern arises: if you have an application that receives a
+few distinct message types, you might define "receiver" structure like
+</p>
+
+<pre>
+type IncomingMessage struct {
+    Cmd *Command
+    Msg *Message
+}
+</pre>
+
+<p>
+and the sending party can populate the <code>Cmd</code> field and/or the
+<code>Msg</code> field of the top-level JSON object, depending on the type of
+message they want to communicate. <code>Unmarshal</code>, when decoding the
+JSON into an <code>IncomingMessage</code> struct, will only allocate the data
+structures present in the JSON data. To know which messages to process, the
+programmer need simply test that either <code>Cmd</code> or <code>Msg</code> is
+not <code>nil</code>.
+</p>
+
+<p>
+<b>Streaming Encoders and Decoders</b>
+</p>
+
+<p>
+The json package provides <code>Decoder</code> and <code>Encoder</code> types
+to support the common operation of reading and writing streams of JSON data.
+The <code>NewDecoder</code> and <code>NewEncoder</code> functions wrap the
+<a href="/pkg/io/#Reader"><code>io.Reader</code></a> and
+<a href="/pkg/io/#Writer"><code>io.Writer</code></a> interface types.
+</p>
+
+<pre>
+func NewDecoder(r io.Reader) *Decoder
+func NewEncoder(w io.Writer) *Encoder
+</pre>
+
+<p>
+Here's an example program that reads a series of JSON objects from standard
+input, removes all but the <code>Name</code> field from each object, and then
+writes the objects to standard output:
+</p>
+
+{{code "/doc/progs/json5.go" `/package main/` `$`}}
+
+<p>
+Due to the ubiquity of Readers and Writers, these <code>Encoder</code> and
+<code>Decoder</code> types can be used in a broad range of scenarios, such as
+reading and writing to HTTP connections, WebSockets, or files.
+</p>

+
+<p>
+Here we present an example where Go's
+<a href="/doc/effective_go.html#interfaces_and_types">interfaces</a> made it
+easy to refactor some existing code to make it more flexible and extensible.
+Originally, the standard library's <a href="/pkg/net/rpc/">RPC package</a> used
+a custom wire format called <a href="/pkg/encoding/gob/">gob</a>. For a
+particular application, we wanted to use <a href="/pkg/encoding/json/">JSON</a>
+as an alternate wire format.
+</p>
+
+<p>
+We first defined a pair of interfaces to describe the functionality of the
+existing wire format, one for the client, and one for the server (depicted
+below).
+</p>
+
+<pre>
+type ServerCodec interface {
+	ReadRequestHeader(*Request) error
+	ReadRequestBody(interface{}) error
+	WriteResponse(*Response, interface{}) error
+	Close() error
+}
+</pre>
+
+<p>
+On the server side, we then changed two internal function signatures to accept
+the <code>ServerCodec</code> interface instead of our existing
+<code>gob.Encoder</code>. Here's one of them:
+</p>
+
+<pre>
+func sendResponse(sending *sync.Mutex, req *Request,
+	reply interface{}, enc *gob.Encoder, errmsg string)
+</pre>
+
+<p>
+became
+</p>
+
+<pre>
+func sendResponse(sending *sync.Mutex, req *Request,
+		reply interface{}, enc ServerCodec, errmsg string)
+</pre>
+
+<p>
+We then wrote a trivial <code>gobServerCodec</code> wrapper to reproduce the
+original functionality. From there it is simple to build a
+<code>jsonServerCodec</code>.
+</p>
+
+<p>
+After some similar changes to the client side, this was the full extent of the
+work we needed to do on the RPC package. This whole exercise took about 20
+minutes! After tidying up and testing the new code, the
+<a href="http://code.google.com/p/go/source/diff?spec=svn9daf796ebf1cae97b2fcf760a4ab682f1f063f29&amp;r=9daf796ebf1cae97b2fcf760a4ab682f1f063f29&amp;format=side&amp;path=/src/pkg/rpc/server.go">final changeset</a>
+was submitted.
+</p>
+
+<p>
+In an inheritance-oriented language like Java or C++, the obvious path would be
+to generalize the RPC class, and create JsonRPC and GobRPC subclasses. However,
+this approach becomes tricky if you want to make a further generalization
+orthogonal to that hierarchy. (For example, if you were to implement an
+alternate RPC standard). In our Go package, we took a route that is both
+conceptually simpler and requires less code be written or changed.
+</p>
+
+<p>
+A vital quality for any codebase is maintainability. As needs change, it is
+essential to adapt your code easily and cleanly, lest it become unwieldy to work
+with. We believe Go's lightweight, composition-oriented type system provides a
+means of structuring code that scales.

+<p>
+Reflection in computing is the
+ability of a program to examine its own structure, particularly
+through types; it's a form of metaprogramming. It's also a great
+source of confusion.
+</p>
+
+<p>
+In this article we attempt to clarify things by explaining how
+reflection works in Go. Each language's reflection model is
+different (and many languages don't support it at all), but
+this article is about Go, so for the rest of this article the word
+"reflection" should be taken to mean "reflection in Go".
+</p>
+
+<p><b>Types and interfaces</b></p>
+
+<p>
+Because reflection builds on the type system, let's start with a
+refresher about types in Go.
+</p>
+
+<p>
+Go is statically typed. Every variable has a static type, that is,
+exactly one type known and fixed at compile time: <code>int</code>,
+<code>float32</code>, <code>*MyType</code>, <code>[]byte</code>,
+and so on. If we declare
+</p>
+
+{{code "/doc/progs/interface.go" `/type MyInt/` `/STOP/`}}
+
+<p>
+then <code>i</code> has type <code>int</code> and <code>j</code>
+has type <code>MyInt</code>. The variables <code>i</code> and
+<code>j</code> have distinct static types and, although they have
+the same underlying type, they cannot be assigned to one another
+without a conversion.
+</p>
+
+<p>
+One important category of type is interface types, which represent
+fixed sets of methods. An interface variable can store any concrete
+(non-interface) value as long as that value implements the
+interface's methods. A well-known pair of examples is
+<code>io.Reader</code> and <code>io.Writer</code>, the types
+<code>Reader</code> and <code>Writer</code> from the
+<a href="/pkg/io/">io package</a>:
+</p>
+
+{{code "/doc/progs/interface.go" `/// Reader/` `/STOP/`}}
+
+<p>
+Any type that implements a <code>Read</code> (or
+<code>Write</code>) method with this signature is said to implement
+<code>io.Reader</code> (or <code>io.Writer</code>). For the
+purposes of this discussion, that means that a variable of type
+<code>io.Reader</code> can hold any value whose type has a
+<code>Read</code> method:
+</p>
+
+{{code "/doc/progs/interface.go" `/func readers/` `/STOP/`}}
+
+<p>
+It's important to be clear that whatever concrete value
+<code>r</code> may hold, <code>r</code>'s type is always
+<code>io.Reader</code>: Go is statically typed and the static type
+of <code>r</code> is <code>io.Reader</code>.</p>
+
+<p>
+An extremely important example of an interface type is the empty
+interface:
+</p>
+
+<pre>
+interface{}
+</pre>
+
+<p>
+It represents the empty set of methods and is satisfied by any
+value at all, since any value has zero or more methods.
+</p>
+
+<p>
+Some people say that Go's interfaces are dynamically typed, but
+that is misleading. They are statically typed: a variable of
+interface type always has the same static type, and even though at
+run time the value stored in the interface variable may change
+type, that value will always satisfy the interface.
+</p>
+
+<p>
+We need to be precise about all this because reflection and
+interfaces are closely related.
+</p>
+
+<p><b>The representation of an interface</b></p>
+
+<p>
+Russ Cox has written a
+<a href="http://research.swtch.com/2009/12/go-data-structures-interfaces.html">detailed blog post</a>
+about the representation of interface values in Go. It's not necessary to
+repeat the full story here, but a simplified summary is in order.
+</p>
+
+<p>
+A variable of interface type stores a pair: the concrete value
+assigned to the variable, and that value's type descriptor.
+To be more precise, the value is the underlying concrete data item
+that implements the interface and the type describes the full type
+of that item. For instance, after
+</p>
+
+{{code "/doc/progs/interface.go" `/func typeAssertions/` `/STOP/`}}
+
+<p>
+<code>r</code> contains, schematically, the (value, type) pair,
+(<code>tty</code>, <code>*os.File</code>). Notice that the type
+<code>*os.File</code> implements methods other than
+<code>Read</code>; even though the interface value provides access
+only to the <code>Read</code> method, the value inside carries all
+the type information about that value. That's why we can do things
+like this:
+</p>
+
+{{code "/doc/progs/interface.go" `/var w io.Writer/` `/STOP/`}}
+
+<p>
+The expression in this assignment is a type assertion; what it
+asserts is that the item inside <code>r</code> also implements
+<code>io.Writer</code>, and so we can assign it to <code>w</code>.
+After the assignment, <code>w</code> will contain the pair
+(<code>tty</code>, <code>*os.File</code>). That's the same pair as
+was held in <code>r</code>. The static type of the interface
+determines what methods may be invoked with an interface variable,
+even though the concrete value inside may have a larger set of
+methods.
+</p>
+
+<p>
+Continuing, we can do this:
+</p>
+
+{{code "/doc/progs/interface.go" `/var empty interface{}/` `/STOP/`}}
+
+<p>
+and our empty interface value <code>e</code> will again contain
+that same pair, (<code>tty</code>, <code>*os.File</code>). That's
+handy: an empty interface can hold any value and contains all the
+information we could ever need about that value.
+</p>
+
+<p>
+(We don't need a type assertion here because it's known statically
+that <code>w</code> satisfies the empty interface. In the example
+where we moved a value from a <code>Reader</code> to a
+<code>Writer</code>, we needed to be explicit and use a type
+assertion because <code>Writer</code>'s methods are not a
+subset of <code>Reader</code>'s.)
+</p>
+
+<p>
+One important detail is that the pair inside an interface always
+has the form (value, concrete type) and cannot have the form
+(value, interface type). Interfaces do not hold interface
+values.
+</p>
+
+<p>
+Now we're ready to reflect.
+</p>
+
+<p><b>The first law of reflection</b></p>
+
+<p><b>1. Reflection goes from interface value to reflection object.</b></p>
+
+<p>
+At the basic level, reflection is just a mechanism to examine the
+type and value pair stored inside an interface variable. To get
+started, there are two types we need to know about in
+<a href="/pkg/reflect/">package reflect</a>:
+<a href="/pkg/reflect/#Type">Type</a> and
+<a href="/pkg/reflect/#Value">Value</a>. Those two types
+give access to the contents of an interface variable, and two
+simple functions, called <code>reflect.TypeOf</code> and
+<code>reflect.ValueOf</code>, retrieve <code>reflect.Type</code>
+and <code>reflect.Value</code> pieces out of an interface value.
+(Also, from the <code>reflect.Value</code> it's easy to get
+to the <code>reflect.Type</code>, but let's keep the
+<code>Value</code> and <code>Type</code> concepts separate for
+now.)
+</p>
+
+<p>
+Let's start with <code>TypeOf</code>:
+</p>
+
+{{code "/doc/progs/interface2.go" `/package main/` `/STOP main/`}}
+
+<p>
+This program prints
+</p>
+
+<pre>
+type: float64
+</pre>
+
+<p>
+You might be wondering where the interface is here, since the program looks
+like it's passing the <code>float64</code> variable <code>x</code>, not an
+interface value, to <code>reflect.TypeOf</code>. But it's there; as
+<a href="/pkg/reflect/#TypeOf">godoc reports</a>, the signature of
+<code>reflect.TypeOf</code> includes an empty interface:
+</p>
+
+<pre>
+// TypeOf returns the reflection Type of the value in the interface{}.
+func TypeOf(i interface{}) Type
+</pre>
+
+<p>
+When we call <code>reflect.TypeOf(x)</code>, <code>x</code> is
+first stored in an empty interface, which is then passed as the
+argument; <code>reflect.TypeOf</code> unpacks that empty interface
+to recover the type information.
+</p>
+
+<p>
+The <code>reflect.ValueOf</code> function, of course, recovers the
+value (from here on we'll elide the boilerplate and focus just on
+the executable code):
+</p>
+
+{{code "/doc/progs/interface2.go" `/START f9/` `/STOP/`}}
+
+<p>
+prints
+</p>
+
+<pre>
+value: &lt;float64 Value&gt;
+</pre>
+
+<p>
+Both <code>reflect.Type</code> and <code>reflect.Value</code> have
+lots of methods to let us examine and manipulate them. One
+important example is that <code>Value</code> has a
+<code>Type</code> method that returns the <code>Type</code> of a
+<code>reflect.Value</code>. Another is that both <code>Type</code>
+and <code>Value</code> have a <code>Kind</code> method that returns
+a constant indicating what sort of item is stored:
+<code>Uint</code>, <code>Float64</code>, <code>Slice</code>, and so
+on. Also methods on <code>Value</code> with names like
+<code>Int</code> and <code>Float</code> let us grab values (as
+<code>int64</code> and <code>float64</code>) stored inside:
+</p>
+
+{{code "/doc/progs/interface2.go" `/START f1/` `/STOP/`}}
+
+<p>
+prints
+</p>
+
+<pre>
+type: float64
+kind is float64: true
+value: 3.4
+</pre>
+
+<p>
+There are also methods like <code>SetInt</code> and
+<code>SetFloat</code> but to use them we need to understand
+settability, the subject of the third law of reflection, discussed
+below.
+</p>
+
+<p>
+The reflection library has a couple of properties worth singling
+out. First, to keep the API simple, the "getter" and "setter"
+methods of <code>Value</code> operate on the largest type that can
+hold the value: <code>int64</code> for all the signed integers, for
+instance. That is, the <code>Int</code> method of
+<code>Value</code> returns an <code>int64</code> and the
+<code>SetInt</code> value takes an <code>int64</code>; it may be
+necessary to convert to the actual type involved:
+</p>
+
+{{code "/doc/progs/interface2.go" `/START f2/` `/STOP/`}}
+
+<p>
+The second property is that the <code>Kind</code> of a reflection
+object describes the underlying type, not the static type. If a
+reflection object contains a value of a user-defined integer type,
+as in
+</p>
+
+{{code "/doc/progs/interface2.go" `/START f3/` `/STOP/`}}
+
+<p>
+the <code>Kind</code> of <code>v</code> is still
+<code>reflect.Int</code>, even though the static type of
+<code>x</code> is <code>MyInt</code>, not <code>int</code>. In
+other words, the <code>Kind</code> cannot discriminate an int from
+a <code>MyInt</code> even though the <code>Type</code> can.
+</p>
+
+<p><b>The second law of reflection</b></p>
+
+<p><b>2. Reflection goes from reflection object to interface
+value.</b></p>
+
+<p>
+Like physical reflection, reflection in Go generates its own
+inverse.
+</p>
+
+<p>
+Given a <code>reflect.Value</code> we can recover an interface
+value using the <code>Interface</code> method; in effect the method
+packs the type and value information back into an interface
+representation and returns the result:
+</p>
+
+<pre>
+// Interface returns v's value as an interface{}.
+func (v Value) Interface() interface{}
+</pre>
+
+<p>
+As a consequence we can say
+</p>
+
+{{code "/doc/progs/interface2.go" `/START f3b/` `/STOP/`}}
+
+<p>
+to print the <code>float64</code> value represented by the
+reflection object <code>v</code>.
+</p>
+
+<p>
+We can do even better, though. The arguments to
+<code>fmt.Println</code>, <code>fmt.Printf</code> and so on are all
+passed as empty interface values, which are then unpacked by the
+<code>fmt</code> package internally just as we have been doing in
+the previous examples. Therefore all it takes to print the contents
+of a <code>reflect.Value</code> correctly is to pass the result of
+the <code>Interface</code> method to the formatted print
+routine:
+</p>
+
+{{code "/doc/progs/interface2.go" `/START f3c/` `/STOP/`}}
+
+<p>
+(Why not <code>fmt.Println(v)</code>? Because <code>v</code> is a
+<code>reflect.Value</code>; we want the concrete value it holds.)
+Since our value is a <code>float64</code>, we can even use a
+floating-point format if we want:
+</p>
+
+{{code "/doc/progs/interface2.go" `/START f3d/` `/STOP/`}}
+
+<p>
+and get in this case
+</p>
+
+<pre>
+3.4e+00
+</pre>
+
+<p>
+Again, there's no need to type-assert the result of
+<code>v.Interface()</code> to <code>float64</code>; the empty
+interface value has the concrete value's type information inside
+and <code>Printf</code> will recover it.
+</p>
+
+<p>
+In short, the <code>Interface</code> method is the inverse of the
+<code>ValueOf</code> function, except that its result is always of
+static type <code>interface{}</code>.
+</p>
+
+<p>
+Reiterating: Reflection goes from interface values to reflection
+objects and back again.
+</p>
+
+<p><b>The third law of reflection</b></p>
+
+<p><b>3. To modify a reflection object, the value must be settable.</b></p>
+
+<p>
+The third law is the most subtle and confusing, but it's easy
+enough to understand if we start from first principles.
+</p>
+
+<p>
+Here is some code that does not work, but is worth studying.
+</p>
+
+{{code "/doc/progs/interface2.go" `/START f4/` `/STOP/`}}
+
+<p>
+If you run this code, it will panic with the cryptic message
+</p>
+
+<pre>
+panic: reflect.Value.SetFloat using unaddressable value
+</pre>
+
+<p>
+The problem is not that the value <code>7.1</code> is not
+addressable; it's that <code>v</code> is not settable. Settability
+is a property of a reflection <code>Value</code>, and not all
+reflection <code>Values</code> have it.
+</p>
+
+<p>
+The <code>CanSet</code> method of <code>Value</code> reports the
+settability of a <code>Value</code>; in our case,
+</p>
+
+{{code "/doc/progs/interface2.go" `/START f5/` `/STOP/`}}
+
+<p>
+prints
+</p>
+
+<pre>
+settability of v: false
+</pre>
+
+<p>
+It is an error to call a <code>Set</code> method on an non-settable
+<code>Value</code>. But what is settability?
+</p>
+
+<p>
+Settability is a bit like addressability, but stricter. It's the
+property that a reflection object can modify the actual storage
+that was used to create the reflection object. Settability is
+determined by whether the reflection object holds the original
+item. When we say
+</p>
+
+{{code "/doc/progs/interface2.go" `/START f6/` `/STOP/`}}
+
+<p>
+we pass a <em>copy</em> of <code>x</code> to
+<code>reflect.ValueOf</code>, so the interface value created as the
+argument to <code>reflect.ValueOf</code> is a <em>copy</em> of
+<code>x</code>, not <code>x</code> itself. Thus, if the
+statement
+</p>
+
+{{code "/doc/progs/interface2.go" `/START f6b/` `/STOP/`}}
+
+<p>
+were allowed to succeed, it would not update <code>x</code>, even
+though <code>v</code> looks like it was created from
+<code>x</code>. Instead, it would update the copy of <code>x</code>
+stored inside the reflection value and <code>x</code> itself would
+be unaffected. That would be confusing and useless, so it is
+illegal, and settability is the property used to avoid this
+issue.
+</p>
+
+<p>
+If this seems bizarre, it's not. It's actually a familiar situation
+in unusual garb. Think of passing <code>x</code> to a
+function:
+</p>
+
+<pre>
+f(x)
+</pre>
+
+<p>
+We would not expect <code>f</code> to be able to modify
+<code>x</code> because we passed a copy of <code>x</code>'s value,
+not <code>x</code> itself. If we want <code>f</code> to modify
+<code>x</code> directly we must pass our function the address of
+<code>x</code> (that is, a pointer to <code>x</code>):</p>
+
+<p>
+<code>f(&amp;x)</code>
+</p>
+
+<p>
+This is straightforward and familiar, and reflection works the same
+way. If we want to modify <code>x</code> by reflection, we must
+give the reflection library a pointer to the value we want to
+modify.
+</p>
+
+<p>
+Let's do that. First we initialize <code>x</code> as usual
+and then create a reflection value that points to it, called
+<code>p</code>.
+</p>
+

+The output so far is

+
+<pre>
+type of p: *float64
+settability of p: false
+</pre>
+
+<p>
+The reflection object <code>p</code> isn't settable, but it's not
+<code>p</code> we want to set, it's (in effect) <code>*p</code>. To
+get to what <code>p</code> points to, we call the <code>Elem</code>
+method of <code>Value</code>, which indirects through the pointer,
+and save the result in a reflection <code>Value</code> called
+<code>v</code>:
+</p>
+
+{{code "/doc/progs/interface2.go" `/START f7b/` `/STOP/`}}
+
+<p>
+Now <code>v</code> is a settable reflection object, as the output

+
+<pre>
+settability of v: true
+</pre>
+
+<p>
+and since it represents <code>x</code>, we are finally able to use

+<p>
+Reflection can be hard to understand but it's doing exactly what
+the language does, albeit through reflection <code>Types</code> and
+<code>Values</code> that can disguise what's going on. Just keep in
+mind that reflection Values need the address of something in order
+to modify what they represent.
+</p>
+
+<p><b>Structs</b></p>
+
+<p>
+In our previous example <code>v</code> wasn't a pointer itself, it
+was just derived from one. A common way for this situation to arise
+is when using reflection to modify the fields of a structure. As
+long as we have the address of the structure, we can modify its
+fields.
+</p>
+
+<p>
+Here's a simple example that analyzes a struct value, <code>t</code>. We create
+the reflection object with the address of the struct because we'll want to
+modify it later. Then we set <code>typeOfT</code> to its type and iterate over
+the fields using straightforward method calls
+(see <a href="/pkg/reflect/">package reflect</a> for details).
+Note that we extract the names of the fields from the struct type, but the
+fields themselves are regular <code>reflect.Value</code> objects.
+</p>
+
+{{code "/doc/progs/interface2.go" `/START f8/` `/STOP/`}}
+
+<p>
+The output of this program is
+</p>
+
+<pre>
+0: A int = 23
+1: B string = skidoo
+</pre>
+
+<p>
+There's one more point about settability introduced in
+passing here: the field names of <code>T</code> are upper case
+(exported) because only exported fields of a struct are
+settable.
+</p>
+
+<p>
+Because <code>s</code> contains a settable reflection object, we
+can modify the fields of the structure.
+</p>
+
+{{code "/doc/progs/interface2.go" `/START f8b/` `/STOP/`}}
+
+<p>
+And here's the result:
+</p>
+
+<pre>
+t is now {77 Sunset Strip}
+</pre>
+
+<p>
+If we modified the program so that <code>s</code> was created from
+<code>t</code>, not <code>&amp;t</code>, the calls to
+<code>SetInt</code> and <code>SetString</code> would fail as the
+fields of <code>t</code> would not be settable.
+</p>
+
+<p><b>Conclusion</b></p>
+
+<p>
+Here again are the laws of reflection:
+</p>
+
+<ol>
+<li>Reflection goes from interface value to reflection
+object.</li>
+<li>Reflection goes from reflection object to interface
+value.</li>
+<li>To modify a reflection object, the value must be settable.</li>
+</ol>
+
+<p>
+Once you understand these laws reflection in Go becomes much easier
+to use, although it remains subtle. It's a powerful tool that
+should be used with care and avoided unless strictly
+necessary.
+</p>
+
+<p>
+There's plenty more to reflection that we haven't covered &mdash;
+sending and receiving on channels, allocating memory, using slices
+and maps, calling methods and functions &mdash; but this post is
+long enough. We'll cover some of those topics in a later
+article.

+<p>
+Go's slice type provides a convenient and efficient means of working with
+sequences of typed data. Slices are analogous to arrays in other languages, but
+have some unusual properties. This article will look at what slices are and how
+they are used.
+</p>
+
+<p>
+<b>Arrays</b>
+</p>
+
+<p>
+The slice type is an abstraction built on top of Go's array type, and so to
+understand slices we must first understand arrays.
+</p>
+
+<p>
+An array type definition specifies a length and an element type. For example,
+the type <code>[4]int</code> represents an array of four integers. An array's
+size is fixed; its length is part of its type (<code>[4]int</code> and
+<code>[5]int</code> are distinct, incompatible types). Arrays can be indexed in
+the usual way, so the expression <code>s[n]</code> accesses the <i>n</i>th
+element:
+</p>
+
+<pre>
+var a [4]int
+a[0] = 1
+i := a[0]
+// i == 1
+</pre>
+
+<p>
+Arrays do not need to be initialized explicitly; the zero value of an array is
+a ready-to-use array whose elements are themselves zeroed:
+</p>
+
+<pre>
+// a[2] == 0, the zero value of the int type
+</pre>
+
+<p>
+The in-memory representation of <code>[4]int</code> is just four integer values laid out sequentially:
+</p>
+
+<p>
+<img src="slice-array.png">
+</p>
+
+<p>
+Go's arrays are values. An array variable denotes the entire array; it is not a
+pointer to the first array element (as would be the case in C).  This means
+that when you assign or pass around an array value you will make a copy of its
+contents. (To avoid the copy you could pass a <i>pointer</i> to the array, but
+then that's a pointer to an array, not an array.) One way to think about arrays
+is as a sort of struct but with indexed rather than named fields: a fixed-size
+composite value.
+</p>
+
+<p>
+An array literal can be specified like so:
+</p>
+
+<pre>
+b := [2]string{"Penn", "Teller"}
+</pre>
+
+<p>
+Or, you can have the compiler count the array elements for you:
+</p>
+
+<pre>
+b := [...]string{"Penn", "Teller"}
+</pre>
+
+<p>
+In both cases, the type of <code>b</code> is <code>[2]string</code>.
+</p>
+
+<p>
+<b>Slices</b>
+</p>
+
+<p>
+Arrays have their place, but they're a bit inflexible, so you don't see them
+too often in Go code. Slices, though, are everywhere. They build on arrays to
+provide great power and convenience.
+</p>
+
+<p>
+The type specification for a slice is <code>[]T</code>, where <code>T</code> is
+the type of the elements of the slice. Unlike an array type, a slice type has
+no specified length.
+</p>
+
+<p>
+A slice literal is declared just like an array literal, except you leave out
+the element count:
+</p>
+
+<pre>
+letters := []string{"a", "b", "c", "d"}
+</pre>
+
+<p>
+A slice can be created with the built-in function called <code>make</code>,
+which has the signature,
+</p>
+
+<pre>
+func make([]T, len, cap) []T
+</pre>
+
+<p>
+where T stands for the element type of the slice to be created. The
+<code>make</code> function takes a type, a length, and an optional capacity.
+When called, <code>make</code> allocates an array and returns a slice that
+refers to that array.
+</p>
+
+<pre>
+var s []byte
+s = make([]byte, 5, 5)
+// s == []byte{0, 0, 0, 0, 0}
+</pre>
+
+<p>
+When the capacity argument is omitted, it defaults to the specified length.
+Here's a more succinct version of the same code:
+</p>
+
+<pre>
+s := make([]byte, 5)
+</pre>
+
+<p>
+The length and capacity of a slice can be inspected using the built-in
+<code>len</code> and <code>cap</code> functions.
+</p>
+
+<pre>
+len(s) == 5
+cap(s) == 5
+</pre>
+
+<p>
+The next two sections discuss the relationship between length and capacity.
+</p>
+
+<p>
+The zero value of a slice is <code>nil</code>. The <code>len</code> and
+<code>cap</code> functions will both return 0 for a nil slice.
+</p>
+
+<p>
+A slice can also be formed by "slicing" an existing slice or array. Slicing is
+done by specifying a half-open range with two indices separated by a colon. For
+example, the expression <code>b[1:4]</code> creates a slice including elements
+1 through 3 of <code>b</code> (the indices of the resulting slice will be 0
+through 2).
+</p>
+
+<pre>
+b := []byte{'g', 'o', 'l', 'a', 'n', 'g'}
+// b[1:4] == []byte{'o', 'l', 'a'}, sharing the same storage as b
+</pre>
+
+<p>
+The start and end indices of a slice expression are optional; they default to zero and the slice's length respectively:
+</p>
+
+<pre>
+// b[:2] == []byte{'g', 'o'}
+// b[2:] == []byte{'l', 'a', 'n', 'g'}
+// b[:] == b
+</pre>
+
+<p>
+This is also the syntax to create a slice given an array:
+</p>
+
+<pre>
+x := [3]string{"Лайка", "Белка", "Стрелка"}
+s := x[:] // a slice referencing the storage of x
+</pre>
+
+<p>
+<b>Slice internals</b>
+</p>
+
+<p>
+A slice is a descriptor of an array segment. It consists of a pointer to the
+array, the length of the segment, and its capacity (the maximum length of the
+segment).
+</p>
+
+<p>
+<img src="slice-struct.png">
+</p>
+
+<p>
+Our variable <code>s</code>, created earlier by <code>make([]byte, 5)</code>,
+is structured like this:
+</p>
+
+<p>
+<img src="slice-1.png">
+</p>
+
+<p>
+The length is the number of elements referred to by the slice. The capacity is
+the number of elements in the underlying array (beginning at the element
+referred to by the slice pointer). The distinction between length and capacity
+will be made clear as we walk through the next few examples.
+</p>
+
+<p>
+As we slice <code>s</code>, observe the changes in the slice data structure and
+their relation to the underlying array:
+</p>
+
+<pre>
+s = s[2:4]
+</pre>
+
+<p>
+<img src="slice-2.png">
+</p>
+
+<p>
+Slicing does not copy the slice's data. It creates a new slice value that
+points to the original array. This makes slice operations as efficient as
+manipulating array indices. Therefore, modifying the <i>elements</i> (not the
+slice itself) of a re-slice modifies the elements of the original slice:
+</p>
+
+<pre>
+d := []byte{'r', 'o', 'a', 'd'}
+e := d[2:] 
+// e == []byte{'a', 'd'}
+e[1] = 'm'
+// e == []byte{'a', 'm'}
+// d == []byte{'r', 'o', 'a', 'm'}
+</pre>
+
+<p>
+Earlier we sliced <code>s</code> to a length shorter than its capacity. We can
+grow s to its capacity by slicing it again:
+</p>
+
+<pre>
+s = s[:cap(s)]
+</pre>
+
+<p>
+<img src="slice-3.png">
+</p>
+
+<p>
+A slice cannot be grown beyond its capacity. Attempting to do so will cause a
+runtime panic, just as when indexing outside the bounds of a slice or array.
+Similarly, slices cannot be re-sliced below zero to access earlier elements in
+the array.
+</p>
+
+<p>
+<b>Growing slices (the copy and append functions)</b>
+</p>
+
+<p>
+To increase the capacity of a slice one must create a new, larger slice and
+copy the contents of the original slice into it. This technique is how dynamic
+array implementations from other languages work behind the scenes. The next
+example doubles the capacity of <code>s</code> by making a new slice,
+<code>t</code>, copying the contents of <code>s</code> into <code>t</code>, and
+then assigning the slice value <code>t</code> to <code>s</code>:
+</p>
+
+<pre>
+t := make([]byte, len(s), (cap(s)+1)*2) // +1 in case cap(s) == 0
+for i := range s {
+        t[i] = s[i]
+}
+s = t
+</pre>
+
+<p>
+The looping piece of this common operation is made easier by the built-in copy
+function. As the name suggests, copy copies data from a source slice to a
+destination slice. It returns the number of elements copied.
+</p>
+
+<pre>
+func copy(dst, src []T) int
+</pre>
+
+<p>
+The <code>copy</code> function supports copying between slices of different
+lengths (it will copy only up to the smaller number of elements). In addition,
+<code>copy</code> can handle source and destination slices that share the same
+underlying array, handling overlapping slices correctly.
+</p>
+
+<p>
+Using <code>copy</code>, we can simplify the code snippet above:
+</p>
+
+<pre>
+t := make([]byte, len(s), (cap(s)+1)*2)
+copy(t, s)
+s = t
+</pre>
+
+<p>
+A common operation is to append data to the end of a slice. This function
+appends byte elements to a slice of bytes, growing the slice if necessary, and
+returns the updated slice value:
+</p>
+
+{{code "/doc/progs/slices.go" `/AppendByte/` `/STOP/`}}
+
+<p>
+One could use <code>AppendByte</code> like this:
+</p>
+
+<pre>
+p := []byte{2, 3, 5}
+p = AppendByte(p, 7, 11, 13)
+// p == []byte{2, 3, 5, 7, 11, 13}
+</pre>
+
+<p>
+Functions like <code>AppendByte</code> are useful because they offer complete
+control over the way the slice is grown. Depending on the characteristics of
+the program, it may be desirable to allocate in smaller or larger chunks, or to
+put a ceiling on the size of a reallocation.
+</p>
+
+<p>
+But most programs don't need complete control, so Go provides a built-in
+<code>append</code> function that's good for most purposes; it has the
+signature
+</p>
+
+<pre>
+func append(s []T, x ...T) []T 
+</pre>
+
+<p>
+The <code>append</code> function appends the elements <code>x</code> to the end
+of the slice <code>s</code>, and grows the slice if a greater capacity is
+needed.
+</p>
+
+<pre>
+a := make([]int, 1)
+// a == []int{0}
+a = append(a, 1, 2, 3)
+// a == []int{0, 1, 2, 3}
+</pre>
+
+<p>
+To append one slice to another, use <code>...</code> to expand the second
+argument to a list of arguments.
+</p>
+
+<pre>
+a := []string{"John", "Paul"}
+b := []string{"George", "Ringo", "Pete"}
+a = append(a, b...) // equivalent to "append(a, b[0], b[1], b[2])"
+// a == []string{"John", "Paul", "George", "Ringo", "Pete"}
+</pre>
+
+<p>
+Since the zero value of a slice (<code>nil</code>) acts like a zero-length
+slice, you can declare a slice variable and then append to it in a loop:
+</p>
+
+{{code "/doc/progs/slices.go" `/Filter/` `/STOP/`}}
+
+<p>
+<b>A possible "gotcha"</b>
+</p>
+
+<p>
+As mentioned earlier, re-slicing a slice doesn't make a copy of the underlying
+array. The full array will be kept in memory until it is no longer referenced.
+Occasionally this can cause the program to hold all the data in memory when
+only a small piece of it is needed.
+</p>
+
+<p>
+For example, this <code>FindDigits</code> function loads a file into memory and
+searches it for the first group of consecutive numeric digits, returning them
+as a new slice.
+</p>
+
+{{code "/doc/progs/slices.go" `/digit/` `/STOP/`}}
+
+<p>
+This code behaves as advertised, but the returned <code>[]byte</code> points
+into an array containing the entire file. Since the slice references the
+original array, as long as the slice is kept around the garbage collector can't
+release the array; the few useful bytes of the file keep the entire contents in
+memory.
+</p>
+
+<p>
+To fix this problem one can copy the interesting data to a new slice before
+returning it:
+</p>
+
+{{code "/doc/progs/slices.go" `/CopyDigits/` `/STOP/`}}
+
+<p>
+A more concise version of this function could be constructed by using
+<code>append</code>. This is left as an exercise for the reader.

-<h2 id="introduction">A Quick Guide to Go's Assembler</h2>
-
-<p>
-This document is a quick outline of the unusual form of assembly language used by the <code>gc</code>
-suite of Go compilers (<code>6g</code>, <code>8g</code>, etc.).
-The document is not comprehensive.
-</p>
-
-<p>
-The assembler is based on the input to the Plan 9 assemblers, which is documented in detail
-<a href="http://plan9.bell-labs.com/sys/doc/asm.html">on the Plan 9 site</a>.
-If you plan to write assembly language, you should read that document although much of it is Plan 9-specific.
-This document provides a summary of the syntax and
-describes the peculiarities that apply when writing assembly code to interact with Go.
-</p>
-
-<p>
-The most important thing to know about Go's assembler is that it is not a direct representation of the underlying machine.
-Some of the details map precisely to the machine, but some do not.
-This is because the compiler suite (see
-<a href="http://plan9.bell-labs.com/sys/doc/compiler.html">this description</a>)
-needs no assembler pass in the usual pipeline.
-Instead, the compiler emits a kind of incompletely defined instruction set, in binary form, which the linker
-then completes.
-In particular, the linker does instruction selection, so when you see an instruction like <code>MOV</code>
-what the linker actually generates for that operation might not be a move instruction at all, perhaps a clear or load.
-Or it might correspond exactly to the machine instruction with that name.
-In general, machine-specific operations tend to appear as themselves, while more general concepts like
-memory move and subroutine call and return are more abstract.
-The details vary with architecture, and we apologize for the imprecision; the situation is not well-defined.
-</p>
-
-<p>
-The assembler program is a way to generate that intermediate, incompletely defined instruction sequence
-as input for the linker.
-If you want to see what the instructions look like in assembly for a given architecture, say amd64, there
-are many examples in the sources of the standard library, in packages such as
-<a href="/pkg/runtime/"><code>runtime</code></a> and
-<a href="/pkg/math/big/"><code>math/big</code></a>.
-You can also examine what the compiler emits as assembly code:

-<h3 id="symbols">Symbols</h3>
-
-<p>
-Some symbols, such as <code>PC</code>, <code>R0</code> and <code>SP</code>, are predeclared and refer to registers.
-There are two other predeclared symbols, <code>SB</code> (static base) and <code>FP</code> (frame pointer).
-All user-defined symbols other than jump labels are written as offsets to these pseudo-registers.
-</p>
-
-<p>
-The <code>SB</code> pseudo-register can be thought of as the origin of memory, so the symbol <code>foo(SB)</code>
-is the name <code>foo</code> as an address in memory.
-This form is used to name global functions and data.
-Adding <code>&lt;&gt;</code> to the name, as in <code>foo&lt;&gt;(SB)</code>, makes the name
-visible only in the current source file, like a top-level <code>static</code> declaration in a C file.
-</p>
-
-<p>
-The <code>FP</code> pseudo-register is a virtual frame pointer
-used to refer to function arguments.
-The compilers maintain a virtual frame pointer and refer to the arguments on the stack as offsets from that pseudo-register.
-Thus <code>0(FP)</code> is the first argument to the function,
-<code>8(FP)</code> is the second (on a 64-bit machine), and so on.
-When referring to a function argument this way, it is conventional to place the name
-at the beginning, as in <code>first_arg+0(FP)</code> and <code>second_arg+8(FP)</code>.
-Some of the assemblers enforce this convention, rejecting plain <code>0(FP)</code> and <code>8(FP)</code>.
-For assembly functions with Go prototypes, <code>go</code> <code>vet</code> will check that the argument names
-and offsets match.
-On 32-bit systems, the low and high 32 bits of a 64-bit value are distinguished by adding
-a <code>_lo</code> or <code>_hi</code> suffix to the name, as in <code>arg_lo+0(FP)</code> or <code>arg_hi+4(FP)</code>.
-If a Go prototype does not name its result, the expected assembly name is <code>ret</code>.
-</p>
-
-<p>
-The <code>SP</code> pseudo-register is a virtual stack pointer
-used to refer to frame-local variables and the arguments being
-prepared for function calls.
-It points to the top of the local stack frame, so references should use negative offsets
-in the range [−framesize, 0):
-<code>x-8(SP)</code>, <code>y-4(SP)</code>, and so on.
-On architectures with a real register named <code>SP</code>, the name prefix distinguishes
-references to the virtual stack pointer from references to the architectural <code>SP</code> register.
-That is, <code>x-8(SP)</code> and <code>-8(SP)</code> are different memory locations:
-the first refers to the virtual stack pointer pseudo-register, while the second refers to the
-hardware's <code>SP</code> register.
-</p>
-
-<p>
-Instructions, registers, and assembler directives are always in UPPER CASE to remind you
-that assembly programming is a fraught endeavor.
-(Exception: the <code>g</code> register renaming on ARM.)
-</p>
-
-<p>
-In Go object files and binaries, the full name of a symbol is the 
-package path followed by a period and the symbol name:
-<code>fmt.Printf</code> or <code>math/rand.Int</code>.
-Because the assembler's parser treats period and slash as punctuation,
-those strings cannot be used directly as identifier names.
-Instead, the assembler allows the middle dot character U+00B7
-and the division slash U+2215 in identifiers and rewrites them to
-plain period and slash.
-Within an assembler source file, the symbols above are written as
-<code>fmt·Printf</code> and <code>math∕rand·Int</code>.
-The assembly listings generated by the compilers when using the <code>-S</code> flag
-show the period and slash directly instead of the Unicode replacements
-required by the assemblers.
-</p>
-
-<p>
-Most hand-written assembly files do not include the full package path
-in symbol names, because the linker inserts the package path of the current
-object file at the beginning of any name starting with a period:
-in an assembly source file within the math/rand package implementation,
-the package's Int function can be referred to as <code>·Int</code>.
-This convention avoids the need to hard-code a package's import path in its
-own source code, making it easier to move the code from one location to another.
-</p>
-
-<h3 id="directives">Directives</h3>
-
-<p>
-The assembler uses various directives to bind text and data to symbol names.
-For example, here is a simple complete function definition. The <code>TEXT</code>
-directive declares the symbol <code>runtime·profileloop</code> and the instructions
-that follow form the body of the function.
-The last instruction in a <code>TEXT</code> block must be some sort of jump, usually a <code>RET</code> (pseudo-)instruction.
-(If it's not, the linker will append a jump-to-itself instruction; there is no fallthrough in <code>TEXTs</code>.)
-After the symbol, the arguments are flags (see below)
-and the frame size, a constant (but see below):
-</p>
-
-<pre>
-TEXT runtime·profileloop(SB),NOSPLIT,$8
-	MOVQ	$runtime·profileloop1(SB), CX
-	MOVQ	CX, 0(SP)
-	CALL	runtime·externalthreadhandler(SB)
-	RET
-</pre>
-
-<p>
-In the general case, the frame size is followed by an argument size, separated by a minus sign.
-(It's not a subtraction, just idiosyncratic syntax.)
-The frame size <code>$24-8</code> states that the function has a 24-byte frame
-and is called with 8 bytes of argument, which live on the caller's frame.
-If <code>NOSPLIT</code> is not specified for the <code>TEXT</code>,
-the argument size must be provided.
-For assembly functions with Go prototypes, <code>go</code> <code>vet</code> will check that the
-argument size is correct.
-</p>
-
-<p>
-Note that the symbol name uses a middle dot to separate the components and is specified as an offset from the
-static base pseudo-register <code>SB</code>.
-This function would be called from Go source for package <code>runtime</code> using the
-simple name <code>profileloop</code>.
-</p>
-
-<p>
-Global data symbols are defined by a sequence of initializing
-<code>DATA</code> directives followed by a <code>GLOBL</code> directive.
-Each <code>DATA</code> directive initializes a section of the
-corresponding memory.
-The memory not explicitly initialized is zeroed.
-The general form of the <code>DATA</code> directive is
-
-<pre>
-DATA	symbol+offset(SB)/width, value
-</pre>
-
-<p>
-which initializes the symbol memory at the given offset and width with the given value.
-The <code>DATA</code> directives for a given symbol must be written with increasing offsets.
-</p>
-
-<p>
-The <code>GLOBL</code> directive declares a symbol to be global.
-The arguments are optional flags and the size of the data being declared as a global,
-which will have initial value all zeros unless a <code>DATA</code> directive
-has initialized it.
-The <code>GLOBL</code> directive must follow any corresponding <code>DATA</code> directives.
-</p>
-
-<p>
-For example,
-</p>
-
-<pre>
-DATA divtab&lt;&gt;+0x00(SB)/4, $0xf4f8fcff
-DATA divtab&lt;&gt;+0x04(SB)/4, $0xe6eaedf0
-...
-DATA divtab&lt;&gt;+0x3c(SB)/4, $0x81828384
-GLOBL divtab&lt;&gt;(SB), RODATA, $64
-
-GLOBL runtime·tlsoffset(SB), NOPTR, $4
-</pre>
-
-<p>
-declares and initializes <code>divtab&lt;&gt;</code>, a read-only 64-byte table of 4-byte integer values,
-and declares <code>runtime·tlsoffset</code>, a 4-byte, implicitly zeroed variable that
-contains no pointers.
-</p>
-
-<p>
-There may be one or two arguments to the directives.
-If there are two, the first is a bit mask of flags,
-which can be written as numeric expressions, added or or-ed together,
-or can be set symbolically for easier absorption by a human.
-Their values, defined in the standard <code>#include</code>  file <code>textflag.h</code>, are:
-</p>
-
-<ul>
-<li>
-<code>NOPROF</code> = 1
-<br>
-(For <code>TEXT</code> items.)
-Don't profile the marked function.  This flag is deprecated.
-</li>
-<li>
-<code>DUPOK</code> = 2
-<br>
-It is legal to have multiple instances of this symbol in a single binary.
-The linker will choose one of the duplicates to use.
-</li>
-<li>
-<code>NOSPLIT</code> = 4
-<br>
-(For <code>TEXT</code> items.)
-Don't insert the preamble to check if the stack must be split.
-The frame for the routine, plus anything it calls, must fit in the
-spare space at the top of the stack segment.
-Used to protect routines such as the stack splitting code itself.
-</li>
-<li>
-<code>RODATA</code> = 8
-<br>
-(For <code>DATA</code> and <code>GLOBL</code> items.)
-Put this data in a read-only section.
-</li>
-<li>
-<code>NOPTR</code> = 16
-<br>
-(For <code>DATA</code> and <code>GLOBL</code> items.)
-This data contains no pointers and therefore does not need to be
-scanned by the garbage collector.
-</li>
-<li>
-<code>WRAPPER</code>  = 32
-<br>
-(For <code>TEXT</code> items.)
-This is a wrapper function and should not count as disabling <code>recover</code>.
-</li>
-</ul>
-
-<h3 id="runtime">Runtime Coordination</h3>
-
-<p>
-For garbage collection to run correctly, the runtime must know the
-location of pointers in all global data and in most stack frames.
-The Go compiler emits this information when compiling Go source files,
-but assembly programs must define it explicitly.
-</p>
-
-<p>
-A data symbol marked with the <code>NOPTR</code> flag (see above)
-is treated as containing no pointers to runtime-allocated data.
-A data symbol with the <code>RODATA</code> flag
-is allocated in read-only memory and is therefore treated
-as implicitly marked <code>NOPTR</code>.
-A data symbol with a total size smaller than a pointer
-is also treated as implicitly marked <code>NOPTR</code>.
-It is not possible to define a symbol containing pointers in an assembly source file;
-such a symbol must be defined in a Go source file instead.
-Assembly source can still refer to the symbol by name
-even without <code>DATA</code> and <code>GLOBL</code> directives.
-A good general rule of thumb is to define all non-<code>RODATA</code>
-symbols in Go instead of in assembly.
-</p>
-
-<p>
-Each function also needs annotations giving the location of
-live pointers in its arguments, results, and local stack frame.
-For an assembly function with no pointer results and
-either no local stack frame or no function calls,
-the only requirement is to define a Go prototype for the function
-in a Go source file in the same package. The name of the assembly
-function must not contain the package name component (for example,
-function <code>Syscall</code> in package <code>syscall</code> should
-use the name <code>·Syscall</code> instead of the equivalent name
-<code>syscall·Syscall</code> in its <code>TEXT</code> directive).
-For more complex situations, explicit annotation is needed.
-These annotations use pseudo-instructions defined in the standard
-<code>#include</code> file <code>funcdata.h</code>.
-</p>
-
-<p>
-If a function has no arguments and no results,
-the pointer information can be omitted.
-This is indicated by an argument size annotation of <code>$<i>n</i>-0</code>
-on the <code>TEXT</code> instruction.
-Otherwise, pointer information must be provided by
-a Go prototype for the function in a Go source file,
-even for assembly functions not called directly from Go.
-(The prototype will also let <code>go</code> <code>vet</code> check the argument references.)
-At the start of the function, the arguments are assumed
-to be initialized but the results are assumed uninitialized.
-If the results will hold live pointers during a call instruction,
-the function should start by zeroing the results and then 
-executing the pseudo-instruction <code>GO_RESULTS_INITIALIZED</code>.
-This instruction records that the results are now initialized
-and should be scanned during stack movement and garbage collection.
-It is typically easier to arrange that assembly functions do not
-return pointers or do not contain call instructions;
-no assembly functions in the standard library use
-<code>GO_RESULTS_INITIALIZED</code>.
-</p>
-
-<p>
-If a function has no local stack frame,
-the pointer information can be omitted.
-This is indicated by a local frame size annotation of <code>$0-<i>n</i></code>
-on the <code>TEXT</code> instruction.
-The pointer information can also be omitted if the
-function contains no call instructions.
-Otherwise, the local stack frame must not contain pointers,
-and the assembly must confirm this fact by executing the 
-pseudo-instruction <code>NO_LOCAL_POINTERS</code>.
-Because stack resizing is implemented by moving the stack,
-the stack pointer may change during any function call:
-even pointers to stack data must not be kept in local variables.
-</p>
-
-<h2 id="architectures">Architecture-specific details</h2>
-
-<p>
-It is impractical to list all the instructions and other details for each machine.
-To see what instructions are defined for a given machine, say 32-bit Intel x86,
-look in the top-level header file for the corresponding linker, in this case <code>8l</code>.
-That is, the file <code>$GOROOT/src/cmd/8l/8.out.h</code> contains a C enumeration, called <code>as</code>,
-of the instructions and their spellings as known to the assembler and linker for that architecture.
-In that file you'll find a declaration that begins
-</p>
-
-<pre>
-enum	as
-{
-	AXXX,
-	AAAA,
-	AAAD,
-	AAAM,
-	AAAS,
-	AADCB,
-	...
-</pre>
-
-<p>
-Each instruction begins with a  initial capital <code>A</code> in this list, so <code>AADCB</code>
-represents the <code>ADCB</code> (add carry byte) instruction.
-The enumeration is in alphabetical order, plus some late additions (<code>AXXX</code> occupies
-the zero slot as an invalid instruction).
-The sequence has nothing to do with the actual encoding of the machine instructions.
-Again, the linker takes care of that detail.
-</p>
-
-<p>
-One detail evident in the examples from the previous sections is that data in the instructions flows from left to right:
-<code>MOVQ</code> <code>$0,</code> <code>CX</code> clears <code>CX</code>.
-This convention applies even on architectures where the usual mode is the opposite direction.
-</p>
-
-<p>
-Here follows some descriptions of key Go-specific details for the supported architectures.
-</p>
-
-<h3 id="x86">32-bit Intel 386</h3>
-
-<p>
-The runtime pointer to the <code>g</code> structure is maintained
-through the value of an otherwise unused (as far as Go is concerned) register in the MMU.
-A OS-dependent macro <code>get_tls</code> is defined for the assembler if the source includes
-an architecture-dependent header file, like this:
-</p>
-
-<pre>
-#include "zasm_GOOS_GOARCH.h"
-</pre>
-
-<p>
-Within the runtime, the <code>get_tls</code> macro loads its argument register
-with a pointer to the <code>g</code> pointer, and the <code>g</code> struct
-contains the <code>m</code> pointer.
-The sequence to load <code>g</code> and <code>m</code> using <code>CX</code> looks like this:
-</p>
-
-<pre>
-get_tls(CX)
-MOVL	g(CX), AX     // Move g into AX.
-MOVL	g_m(AX), BX   // Move g->m into BX.
-</pre>
-
-<h3 id="amd64">64-bit Intel 386 (a.k.a. amd64)</h3>
-
-<p>
-The assembly code to access the <code>m</code> and <code>g</code>
-pointers is the same as on the 386, except it uses <code>MOVQ</code> rather than
-<code>MOVL</code>:
-</p>
-
-<pre>
-get_tls(CX)
-MOVQ	g(CX), AX     // Move g into AX.
-MOVQ	g_m(AX), BX   // Move g->m into BX.
-</pre>
-
-<h3 id="arm">ARM</h3>
-
-<p>
-The registers <code>R10</code> and <code>R11</code>
-are reserved by the compiler and linker.
-</p>
-
-<p>
-<code>R10</code> points to the <code>g</code> (goroutine) structure.
-Within assembler source code, this pointer must be referred to as <code>g</code>;
-the name <code>R10</code> is not recognized.
-</p>
-
-<p>
-To make it easier for people and compilers to write assembly, the ARM linker
-allows general addressing forms and pseudo-operations like <code>DIV</code> or <code>MOD</code>
-that may not be expressible using a single hardware instruction.
-It implements these forms as multiple instructions, often using the <code>R11</code> register
-to hold temporary values.
-Hand-written assembly can use <code>R11</code>, but doing so requires
-being sure that the linker is not also using it to implement any of the other
-instructions in the function.
-</p>
-
-<p>
-When defining a <code>TEXT</code>, specifying frame size <code>$-4</code>
-tells the linker that this is a leaf function that does not need to save <code>LR</code> on entry.
-</p>
-
-<p>
-The name <code>SP</code> always refers to the virtual stack pointer described earlier.
-For the hardware register, use <code>R13</code>.
-</p>
-
-<h3 id="unsupported_opcodes">Unsupported opcodes</h3>
-
-<p>
-The assemblers are designed to support the compiler so not all hardware instructions
-are defined for all architectures: if the compiler doesn't generate it, it might not be there.
-If you need to use a missing instruction, there are two ways to proceed.
-One is to update the assembler to support that instruction, which is straightforward
-but only worthwhile if it's likely the instruction will be used again.
-Instead, for simple one-off cases, it's possible to use the <code>BYTE</code>
-and <code>WORD</code> directives
-to lay down explicit data into the instruction stream within a <code>TEXT</code>.
-Here's how the 386 runtime defines the 64-bit atomic load function.
-</p>
-
-<pre>
-// uint64 atomicload64(uint64 volatile* addr);
-// so actually
-// void atomicload64(uint64 *res, uint64 volatile *addr);
-TEXT runtime·atomicload64(SB), NOSPLIT, $0-8
-	MOVL	ptr+0(FP), AX
-	LEAL	ret_lo+4(FP), BX
-	BYTE $0x0f; BYTE $0x6f; BYTE $0x00	// MOVQ (%EAX), %MM0
-	BYTE $0x0f; BYTE $0x7f; BYTE $0x03	// MOVQ %MM0, 0(%EBX)

-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.

-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

-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>.

-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 <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>

-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

-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

-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.

-<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.

-
-<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
-support throughout the system has been upgraded from
-Unicode 6.2.0 to <a href="http://www.unicode.org/versions/Unicode6.3.0/">Unicode 6.3.0</a>.

-<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="os">Changes to the supported operating systems and architectures</h2>
-
-<h3 id="android">Android</h3>
-
-<p>
-Go 1.4 can build binaries for ARM processors running the Android operating system.
-It can also build a <code>.so</code> library that can be loaded by an Android application
-using the supporting packages in the <a href="https://golang.org/x/mobile">mobile</a> subrepository.
-A brief description of the plans for this experimental port are available
-<a href="https://golang.org/s/go14android">here</a>.
-</p>
-
-<h3 id="naclarm">NaCl on ARM</h3>
-
-<p>
-The previous release introduced Native Client (NaCl) support for the 32-bit x86
-(<code>GOARCH=386</code>)
-and 64-bit x86 using 32-bit pointers (GOARCH=amd64p32).
-The 1.4 release adds NaCl support for ARM (GOARCH=arm).
-</p>
-
-<h3 id="plan9amd64">Plan9 on AMD64</h3>
-
-<p>
-This release adds support for the Plan 9 operating system on AMD64 processors,
-provided the kernel supports the <code>nsec</code> system call and uses 4K pages.
-</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>

-<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/crypo/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>
-The <a href="/pkg/image/png/"><code>image/png</code></a> package now has an
-<a href="/pkg/image/png/#Encoder"><code>Encoder</code></a>
-type to control the compression level used for encoding.
-</li>
-
-<li>
-The <a href="/pkg/math/"><code>math</code></a> package now has a
-<a href="/pkg/math/#Nextafter32"><code>Nextafter32</code><a/> function.
-</li>
-
-<li>
-The <a href="/pkg/net/http/"><code>net/http</code></a> package's
-<a href="/pkg/net/http/#Request"><code>Request</code></a> type
-has a new <a href="/pkg/net/http/#Request.BasicAuth"><code>BasicAuth</code></a> method
-that returns the username and password from authenticated requests using the
-HTTP Basic Authentication
-Scheme.
-</li>
-
-<li>The <a href="/pkg/net/http/"><code>net/http</code></a> package's
-<a href="/pkg/net/http/#Request"><code>Transport</code></a> type
-has a new <a href="/pkg/net/http/#Transport.DialTLS"><code>DialTLS</code></a> hook
-that allows customizing the behavior of outbound TLS connections.
-</li>
-
-<li>
-The <a href="/pkg/net/http/httputil/"><code>net/http/httputil</code></a> package's
-<a href="/pkg/net/http/httputil/#ReverseProxy"><code>ReverseProxy</code></a> type
-has a new field,
-<a href="/pkg/net/http/#ReverseProxy.ErrorLog"><code>ErrorLog</code></a>, that
-provides user control of logging.
-</li>
-
-<li>
-The <a href="/pkg/os/"><code>os</code></a> package
-now implements symbolic links on the Windows operating system
-through the <a href="/pkg/os/#Symlink"><code>Symlink</code></a> function.
-Other operating systems already have this functionality.
-There is also a new <a href="/pkg/os/#Unsetenv"><code>Unsetenv</code></a> function.
-</li>
-
-<li>
-The <a href="/pkg/reflect/"><code>reflect</code></a> package's
-<a href="/pkg/reflect/#Type"><code>Type</code></a> interface
-has a new method, <a href="/pkg/reflect/#type.Comparable"><code>Comparable</code></a>,
-that reports whether the type implements general comparisons.
-</li>
-
-<li>
-Also in the <a href="/pkg/reflect/"><code>reflect</code></a> package, the
-<a href="/pkg/reflect/#Value"><code>Value</code></a> interface is now three instead of four words
-because of changes to the implementation of interfaces in the runtime.
-This saves memory but has no semantic effect.
-</li>
-
-<li>
-The <a href="/pkg/runtime/"><code>runtime</code></a> package
-now implements monotonic clocks on Windows,
-as it already did for the other systems.
-</li>
-
-<li>
-The <a href="/pkg/runtime/"><code>runtime</code></a> package's
-<a href="/pkg/runtime/#MemStats.Mallocs"><code>Mallocs</code></a> counter
-now counts very small allocations that were missed in Go 1.3.
-This may break tests using <a href="/pkg/runtime/#ReadMemStats"><code>ReadMemStats</code></a>
-or <a href="/pkg/testing/#AllocsPerRun"><code>AllocsPerRun</code></a>
-due to the more accurate answer.
-</li>
-
-<li>
-In the <a href="/pkg/runtime/"><code>runtime</code></a> package,
-an array <a href="/pkg/runtime/#MemStats.PauseEnd"><code>PauseEnd</code></a>
-has been added to the
-<a href="/pkg/runtime/#MemStats"><code>MemStats</code></a>
-and <a href="/pkg/runtime/#GCStats"><code>GCStats</code></a> structs.
-This array is a circular buffer of times when garbage collection pauses ended.
-The corresponding pause durations are already recorded in
-<a href="/pkg/runtime/#MemStats.PauseNs"><code>PauseNs</code></a>
-</li>
-
-<li>
-The <a href="/pkg/runtime/race/"><code>runtime/race</code></a> package
-now supports FreeBSD, which means the
-<a href="/pkg/cmd/go/"><code>go</code></a> command's <code>-race</code>
-flag now works on FreeBSD.
-</li>
-
-<li>
-The <a href="/pkg/sync/atomic/"><code>sync/atomic</code></a> package
-has a new type, <a href="/pkg/sync/atomic/#Value"><code>Value</code></a>.
-<code>Value</code> provides an efficient mechanism for atomic loads and
-stores of values of arbitrary type.
-</li>
-
-<li>
-In the <a href="/pkg/syscall/"><code>syscall</code></a> package's
-implementation on Linux, the
-<a href="/pkg/syscall/#Setuid"><code>Setuid</code></a>
-and <a href="/pkg/syscall/#Setgid"><code>Setgid</code></a> have been disabled
-because those system calls operate on the calling thread, not the whole process, which is
-different from other platforms and not the expected result.
-</li>
-
-<li>
-The <a href="/pkg/testing/"><code>testing</code></a> package
-has a new facility to provide more control over running a set of tests.
-If the test code contains a function
-<pre>
-func TestMain(m *<a href="/pkg/testing/#M"><code>testing.M</code></a>) 
-</pre>
-
-that function will be called instead of running the tests directly.
-The <code>M</code> struct contains methods to access and run the tests.
-</li>
-
-<li>
-Also in the <a href="/pkg/testing/"><code>testing</code></a> package,
-a new <a href="/pkg/testing/#Coverage"><code>Coverage</code></a>
-function reports the current test coverage fraction,
-enabling individual tests to report how much they are contributing to the
-overall coverage.
-</li>
-
-<li>
-The <a href="/pkg/text/scanner/"><code>text/scanner</code></a> package's
-<a href="/pkg/text/scanner/#Scanner"><code>Scanner</code></a> type
-has a new function,
-<a href="/pkg/text/scanner/#Scanner.IsIdentRune"><code>IsIdentRune</code></a>,
-allowing one to control the definition of an identifier when scanning.
-</li>
-
-<li>
-The <a href="/pkg/text/template/"><code>text/template</code></a> package's boolean
-functions <code>eq</code>, <code>lt</code>, and so on have been generalized to allow comparison
-of signed and unsigned integers, simplifying their use in practice.
-(Previously one could only compare values of the same signedness.)
-All negative values compare less than all unsigned values.
-</li>
-
-<li>
-The <code>time</code> package now uses the standard symbol for the micro prefix,
-the micro symbol (U+00B5 'µ'), to print microsecond durations.
-<a href="/pkg/time/#ParseDuration"><code>ParseDuration</code></a> still accepts <code>us</code>
-but the package no longer prints microseconds as <code>us</code>.
-<br>
-<em>Updating</em>: Code that depends on the output format of durations
-but does not use ParseDuration will need to be updated.
-</li>
-

-	- mentioning SP or PC as a hardware register
-		These are always pseudo-registers except that in some contexts

-		which register you mean. Change the references to the hardware
-		registers to be explicit: R13 for SP, R15 for PC.
-	- constant creation using assignment
-		The files say a=b when they could instead say #define a b.
-		There is no reason to have both mechanisms.
-	- R(0) to refer to R0.
-		Some macros use this to a great extent. Again, it's easy just to
-		use a #define to rename a register.
-	
-Also expression evaluation now uses uint64s instead of signed integers and the
-precedence of operators is now Go-like rather than C-like.
