-# Contributing to Go
-
-Go is an open source project.
-
-It is the work of hundreds of contributors. We appreciate your help!
-
-## Before filing an issue
-
-If you are unsure whether you have found a bug, please consider asking in the [golang-nuts mailing
-list](https://groups.google.com/forum/#!forum/golang-nuts) or [other forums](https://golang.org/help/) first. If
-the behavior you are seeing is confirmed as a bug or issue, it can easily be re-raised in the issue tracker.
-
-## Filing issues
-
-Sensitive security-related issues should be reported to [security@golang.org](mailto:security@golang.org).
-See the [security policy](https://golang.org/security) for details.
-
-The recommended way to file an issue is by running `go bug`.
-Otherwise, 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?
-
-For change proposals, see [Proposing Changes To Go](https://github.com/golang/proposal/).
-
-## Contributing code
-
-Please read the [Contribution Guidelines](https://golang.org/doc/contribute.html) before sending patches.
-
-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-source.html
+in your web browser.
+
+After installing Go, you can view a nicely formatted
+doc/install-source.html by running godoc --http=:6060
+and then visiting http://localhost:6060/doc/install/source.
+
+Unless otherwise noted, the Go source files are distributed

+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.

-<p>
-Although the assembler takes its guidance from the Plan 9 assemblers,
-it is a distinct program, so there are some differences.
-One is in constant evaluation.
-Constant expressions in the assembler are parsed using Go's operator
-precedence, not the C-like precedence of the original.
-Thus <code>3&amp;1<<2</code> is 4, not 0—it parses as <code>(3&amp;1)<<2</code>
-not <code>3&amp;(1<<2)</code>.
-Also, constants are always evaluated as 64-bit unsigned integers.
-Thus <code>-2</code> is not the integer value minus two,
-but the unsigned 64-bit integer with the same bit pattern.
-The distinction rarely matters but
-to avoid ambiguity, division or right shift where the right operand's
-high bit is set is rejected.

+
+<p>
+This document demonstrates the development of a simple Go package and
+introduces the <a href="/cmd/go/">go tool</a>, the standard way to fetch,
+build, and install Go packages and commands.
+</p>
+
+<p>
+The <code>go</code> tool requires you to organize your code in a specific
+way. Please read this document carefully.
+It explains the simplest way to get up and running with your Go installation.
+</p>
+
+<p>
+A similar explanation is available as a
+<a href="//www.youtube.com/watch?v=XCsL89YtqCs">screencast</a>.
+</p>
+
+
+<h2 id="Organization">Code organization</h2>
+
+<h3 id="Workspaces">Workspaces</h3>
+
+<p>
+The <code>go</code> tool is designed to work with open source code maintained
+in public repositories. Although you don't need to publish your code, the model
+for how the environment is set up works the same whether you do or not.
+</p>
+
+<p>
+Go code must be kept inside a <i>workspace</i>.
+A workspace is a directory hierarchy with three directories at its root:
+</p>
+
+<ul>
+<li><code>src</code> contains Go source files organized into packages (one package per directory),
+<li><code>pkg</code> contains package objects, and
+<li><code>bin</code> contains executable commands.
+</ul>
+
+<p>
+The <code>go</code> tool builds source packages and installs the resulting
+binaries to the <code>pkg</code> and <code>bin</code> directories.
+</p>
+
+<p>
+The <code>src</code> subdirectory typically contains multiple version control
+repositories (such as for Git or Mercurial) that track the development of one
+or more source packages.
+</p>
+
+<p>
+To give you an idea of how a workspace looks in practice, here's an example:
+</p>
+
+<pre>
+bin/
+    hello                          # command executable
+    outyet                         # command executable
+pkg/
+    linux_amd64/
+        github.com/golang/example/
+            stringutil.a           # package object
+src/
+    <a href="https://github.com/golang/example/">github.com/golang/example/</a>
+        .git/                      # Git repository metadata
+	hello/
+	    hello.go               # command source
+	outyet/
+	    main.go                # command source
+	    main_test.go           # test source
+	stringutil/
+	    reverse.go             # package source
+	    reverse_test.go        # test source
+</pre>
+
+<p>
+This workspace contains one repository (<code>example</code>)
+comprising two commands (<code>hello</code> and <code>outyet</code>)
+and one library (<code>stringutil</code>).
+</p>
+
+<p>
+A typical workspace would contain many source repositories containing many
+packages and commands. Most Go programmers keep <i>all</i> their Go source code
+and dependencies in a single workspace.
+</p>
+
+<p>
+Commands and libraries are built from different kinds of source packages.
+We will discuss the distinction <a href="#PackageNames">later</a>.
+</p>
+
+
+<h3 id="GOPATH">The <code>GOPATH</code> environment variable</h3>
+
+<p>
+The <code>GOPATH</code> environment variable specifies the location of your
+workspace. It is likely the only environment variable you'll need to set
+when developing Go code.
+</p>
+
+<p>
+To get started, create a workspace directory and set <code>GOPATH</code>
+accordingly. Your workspace can be located wherever you like, but we'll use
+<code>$HOME/go</code> in this document. Note that this must <b>not</b> be the
+same path as your Go installation.
+</p>
+
+<pre>
+$ <b>mkdir $HOME/go</b>
+$ <b>export GOPATH=$HOME/go</b>
+</pre>
+
+<p>
+For convenience, add the workspace's <code>bin</code> subdirectory
+to your <code>PATH</code>:
+</p>
+
+<pre>
+$ <b>export PATH=$PATH:$GOPATH/bin</b>
+</pre>
+
+
+<h3 id="PackagePaths">Package paths</h3>
+
+<p>
+The packages from the standard library are given short paths such as
+<code>"fmt"</code> and <code>"net/http"</code>.
+For your own packages, you must choose a base path that is unlikely to
+collide with future additions to the standard library or other external
+libraries.
+</p>
+
+<p>
+If you keep your code in a source repository somewhere, then you should use the
+root of that source repository as your base path.
+For instance, if you have a <a href="https://github.com/">GitHub</a> account at
+<code>github.com/user</code>, that should be your base path.
+</p>
+
+<p>
+Note that you don't need to publish your code to a remote repository before you
+can build it. It's just a good habit to organize your code as if you will
+publish it someday. In practice you can choose any arbitrary path name,
+as long as it is unique to the standard library and greater Go ecosystem.
+</p>
+
+<p>
+We'll use <code>github.com/user</code> as our base path. Create a directory
+inside your workspace in which to keep source code:
+</p>
+
+<pre>
+$ <b>mkdir -p $GOPATH/src/github.com/user</b>
+</pre>
+
+
+<h3 id="Command">Your first program</h3>
+
+<p>
+To compile and run a simple program, first choose a package path (we'll use
+<code>github.com/user/hello</code>) and create a corresponding package directory
+inside your workspace:
+</p>
+
+<pre>
+$ <b>mkdir $GOPATH/src/github.com/user/hello</b>
+</pre>
+
+<p>
+Next, create a file named <code>hello.go</code> inside that directory,
+containing the following Go code.
+</p>
+
+<pre>
+package main
+
+import "fmt"
+
+func main() {
+	fmt.Printf("Hello, world.\n")
+}
+</pre>
+
+<p>
+Now you can build and install that program with the <code>go</code> tool:
+</p>
+
+<pre>
+$ <b>go install github.com/user/hello</b>
+</pre>
+
+<p>
+Note that you can run this command from anywhere on your system. The
+<code>go</code> tool finds the source code by looking for the
+<code>github.com/user/hello</code> package inside the workspace specified by
+<code>GOPATH</code>.
+</p>
+
+<p>
+You can also omit the package path if you run <code>go install</code> from the
+package directory:
+</p>
+
+<pre>
+$ <b>cd $GOPATH/src/github.com/user/hello</b>
+$ <b>go install</b>
+</pre>
+
+<p>
+This command builds the <code>hello</code> command, producing an executable
+binary. It then installs that binary to the workspace's <code>bin</code>
+directory as <code>hello</code> (or, under Windows, <code>hello.exe</code>).
+In our example, that will be <code>$GOPATH/bin/hello</code>, which is
+<code>$HOME/go/bin/hello</code>.
+</p>
+
+<p>
+The <code>go</code> tool will only print output when an error occurs, so if
+these commands produce no output they have executed successfully.
+</p>
+
+<p>
+You can now run the program by typing its full path at the command line:
+</p>
+
+<pre>
+$ <b>$GOPATH/bin/hello</b>
+Hello, world.
+</pre>
+
+<p>
+Or, as you have added <code>$GOPATH/bin</code> to your <code>PATH</code>,
+just type the binary name:
+</p>
+
+<pre>
+$ <b>hello</b>
+Hello, world.
+</pre>
+
+<p>
+If you're using a source control system, now would be a good time to initialize
+a repository, add the files, and commit your first change. Again, this step is
+optional: you do not need to use source control to write Go code.
+</p>
+
+<pre>
+$ <b>cd $GOPATH/src/github.com/user/hello</b>
+$ <b>git init</b>
+Initialized empty Git repository in /home/user/go/src/github.com/user/hello/.git/
+$ <b>git add hello.go</b>
+$ <b>git commit -m "initial commit"</b>
+[master (root-commit) 0b4507d] initial commit
+ 1 file changed, 1 insertion(+)
+  create mode 100644 hello.go
+</pre>
+
+<p>
+Pushing the code to a remote repository is left as an exercise for the reader.
+</p>
+
+
+<h3 id="Library">Your first library</h3>
+
+<p>
+Let's write a library and use it from the <code>hello</code> program.
+</p>
+
+<p>
+Again, the first step is to choose a package path (we'll use
+<code>github.com/user/stringutil</code>) and create the package directory:
+</p>
+
+<pre>
+$ <b>mkdir $GOPATH/src/github.com/user/stringutil</b>
+</pre>
+
+<p>
+Next, create a file named <code>reverse.go</code> in that directory with the
+following contents.
+</p>
+
+<pre>
+// Package stringutil contains utility functions for working with strings.
+package stringutil
+
+// Reverse returns its argument string reversed rune-wise left to right.
+func Reverse(s string) string {
+	r := []rune(s)
+	for i, j := 0, len(r)-1; i &lt; len(r)/2; i, j = i+1, j-1 {
+		r[i], r[j] = r[j], r[i]
+	}
+	return string(r)
+}
+</pre>
+
+<p>
+Now, test that the package compiles with <code>go build</code>:
+</p>
+
+<pre>
+$ <b>go build github.com/user/stringutil</b>
+</pre>
+
+<p>
+Or, if you are working in the package's source directory, just:
+</p>
+
+<pre>
+$ <b>go build</b>
+</pre>
+
+<p>
+This won't produce an output file. To do that, you must use <code>go
+install</code>, which places the package object inside the <code>pkg</code>
+directory of the workspace.
+</p>
+
+<p>
+After confirming that the <code>stringutil</code> package builds,
+modify your original <code>hello.go</code> (which is in
+<code>$GOPATH/src/github.com/user/hello</code>) to use it:
+</p>
+
+<pre>
+package main
+
+import (
+	"fmt"
+
+	<b>"github.com/user/stringutil"</b>
+)
+
+func main() {
+	fmt.Printf(stringutil.Reverse("!oG ,olleH"))
+}
+</pre>
+
+<p>
+Whenever the <code>go</code> tool installs a package or binary, it also
+installs whatever dependencies it has.
+So when you install the <code>hello</code> program
+</p>
+
+<pre>
+$ <b>go install github.com/user/hello</b>
+</pre>
+
+<p>
+the <code>stringutil</code> package will be installed as well, automatically.
+</p>
+
+<p>
+Running the new version of the program, you should see a new, reversed message:
+</p>
+
+<pre>
+$ <b>hello</b>
+Hello, Go!
+</pre>
+
+<p>
+After the steps above, your workspace should look like this:
+</p>
+
+<pre>
+bin/
+    hello                 # command executable
+pkg/
+    linux_amd64/          # this will reflect your OS and architecture
+        github.com/user/
+            stringutil.a  # package object
+src/
+    github.com/user/
+        hello/
+            hello.go      # command source
+        stringutil/
+            reverse.go    # package source
+</pre>
+
+<p>
+Note that <code>go install</code> placed the <code>stringutil.a</code> object
+in a directory inside <code>pkg/linux_amd64</code> that mirrors its source
+directory.
+This is so that future invocations of the <code>go</code> tool can find the
+package object and avoid recompiling the package unnecessarily.
+The <code>linux_amd64</code> part is there to aid in cross-compilation,
+and will reflect the operating system and architecture of your system.
+</p>
+
+<p>
+Go command executables are statically linked; the package objects need not
+be present to run Go programs.
+</p>
+
+
+<h3 id="PackageNames">Package names</h3>
+
+<p>
+The first statement in a Go source file must be
+</p>
+
+<pre>
+package <i>name</i>
+</pre>
+
+<p>
+where <code><i>name</i></code> is the package's default name for imports.
+(All files in a package must use the same <code><i>name</i></code>.)
+</p>
+
+<p>
+Go's convention is that the package name is the last element of the
+import path: the package imported as "<code>crypto/rot13</code>"
+should be named <code>rot13</code>.
+</p>
+
+<p>
+Executable commands must always use <code>package main</code>.
+</p>
+
+<p>
+There is no requirement that package names be unique
+across all packages linked into a single binary,
+only that the import paths (their full file names) be unique.
+</p>
+
+<p>
+See <a href="/doc/effective_go.html#names">Effective Go</a> to learn more about
+Go's naming conventions.
+</p>
+
+
+<h2 id="Testing">Testing</h2>
+
+<p>
+Go has a lightweight test framework composed of the <code>go test</code>
+command and the <code>testing</code> package.
+</p>
+
+<p>
+You write a test by creating a file with a name ending in <code>_test.go</code>
+that contains functions named <code>TestXXX</code> with signature
+<code>func (t *testing.T)</code>.
+The test framework runs each such function;
+if the function calls a failure function such as <code>t.Error</code> or
+<code>t.Fail</code>, the test is considered to have failed.
+</p>
+
+<p>
+Add a test to the <code>stringutil</code> package by creating the file
+<code>$GOPATH/src/github.com/user/stringutil/reverse_test.go</code> containing
+the following Go code.
+</p>
+
+<pre>
+package stringutil
+
+import "testing"
+
+func TestReverse(t *testing.T) {
+	cases := []struct {
+		in, want string
+	}{
+		{"Hello, world", "dlrow ,olleH"},
+		{"Hello, 世界", "界世 ,olleH"},
+		{"", ""},
+	}
+	for _, c := range cases {
+		got := Reverse(c.in)
+		if got != c.want {
+			t.Errorf("Reverse(%q) == %q, want %q", c.in, got, c.want)
+		}
+	}
+}
+</pre>
+
+<p>
+Then run the test with <code>go test</code>:
+</p>
+
+<pre>
+$ <b>go test github.com/user/stringutil</b>
+ok  	github.com/user/stringutil 0.165s
+</pre>
+
+<p>
+As always, if you are running the <code>go</code> tool from the package
+directory, you can omit the package path:
+</p>
+
+<pre>
+$ <b>go test</b>
+ok  	github.com/user/stringutil 0.165s
+</pre>
+
+<p>
+Run <code><a href="/cmd/go/#hdr-Test_packages">go help test</a></code> and see the
+<a href="/pkg/testing/">testing package documentation</a> for more detail.
+</p>
+
+
+<h2 id="remote">Remote packages</h2>
+
+<p>
+An import path can describe how to obtain the package source code using a
+revision control system such as Git or Mercurial. The <code>go</code> tool uses
+this property to automatically fetch packages from remote repositories.
+For instance, the examples described in this document are also kept in a
+Git repository hosted at GitHub
+<code><a href="https://github.com/golang/example">github.com/golang/example</a></code>.
+If you include the repository URL in the package's import path,
+<code>go get</code> will fetch, build, and install it automatically:
+</p>
+
+<pre>
+$ <b>go get github.com/golang/example/hello</b>
+$ <b>$GOPATH/bin/hello</b>
+Hello, Go examples!
+</pre>
+
+<p>
+If the specified package is not present in a workspace, <code>go get</code>
+will place it inside the first workspace specified by <code>GOPATH</code>.
+(If the package does already exist, <code>go get</code> skips the remote
+fetch and behaves the same as <code>go install</code>.)
+</p>
+
+<p>
+After issuing the above <code>go get</code> command, the workspace directory
+tree should now look like this:
+</p>
+
+<pre>
+bin/
+    hello                           # command executable
+pkg/
+    linux_amd64/
+        github.com/golang/example/
+            stringutil.a            # package object
+        github.com/user/
+            stringutil.a            # package object
+src/
+    github.com/golang/example/
+	.git/                       # Git repository metadata
+        hello/
+            hello.go                # command source
+        stringutil/
+            reverse.go              # package source
+            reverse_test.go         # test source
+    github.com/user/
+        hello/
+            hello.go                # command source
+        stringutil/
+            reverse.go              # package source
+            reverse_test.go         # test source
+</pre>
+
+<p>
+The <code>hello</code> command hosted at GitHub depends on the
+<code>stringutil</code> package within the same repository. The imports in
+<code>hello.go</code> file use the same import path convention, so the
+<code>go get</code> command is able to locate and install the dependent
+package, too.
+</p>
+
+<pre>
+import "github.com/golang/example/stringutil"
+</pre>
+
+<p>
+This convention is the easiest way to make your Go packages available for
+others to use.

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

+<h2 id="r59">r59 (released 2011/08/01)</h2>
+
+<p>
+The r59 release corresponds to 
+<code><a href="weekly.html#2011-07-07">weekly.2011-07-07</a></code>.
+This section highlights the most significant changes in this release.
+For a more detailed summary, see the

+</p>
+
+<h3 id="r59.lang">Language</h3>
+
+<p>
+This release includes a language change that restricts the use of
+<code>goto</code>.  In essence, a <code>goto</code> statement outside a block
+cannot jump to a label inside that block. Your code may require changes if it
+uses <code>goto</code>.
+See <a href="//golang.org/change/dc6d3cf9279d">this
+changeset</a> for how the new rule affected the Go tree.
+</p>
+
+<h3 id="r59.pkg">Packages</h3>
+
+<p>
+As usual, <a href="/cmd/gofix/">gofix</a> will handle the bulk of the rewrites
+necessary for these changes to package APIs.
+</p>
+
+<p>
+<a href="/pkg/http">Package http</a> has a new
+<a href="/pkg/http/#FileSystem">FileSystem</a> interface that provides access
+to files. The <a href="/pkg/http/#FileServer">FileServer</a> helper now takes a
+<code>FileSystem</code> argument instead of an explicit file system root. By
+implementing your own <code>FileSystem</code> you can use the
+<code>FileServer</code> to serve arbitrary data.
+</p>
+
+<p>
+<a href="/pkg/os/">Package os</a>'s <code>ErrorString</code> type has been
+hidden. Most uses of <code>os.ErrorString</code> can be replaced with
+<a href="/pkg/os/#NewError">os.NewError</a>.
+</p>
+
+<p>
+<a href="/pkg/reflect/">Package reflect</a> supports a new struct tag scheme
+that enables sharing of struct tags between multiple packages.
+In this scheme, the tags must be of the form:
+</p>
+<pre>
+	`key:"value" key2:"value2"`
+</pre>
+<p>
+The <a href="/pkg/reflect/#StructField">StructField</a> type's Tag field now
+has type <a href="/pkg/reflect/#StructTag">StructTag</a>, which has a
+<code>Get</code> method. Clients of <a href="/pkg/json">json</a> and
+<a href="/pkg/xml">xml</a> will need to be updated. Code that says
+</p>
+<pre>
+	type T struct {
+		X int "name"
+	}
+</pre>
+<p>
+should become
+</p>
+<pre>
+	type T struct {
+		X int `json:"name"`  // or `xml:"name"`
+	}
+</pre>
+<p>
+Use <a href="/cmd/govet/">govet</a> to identify struct tags that need to be
+changed to use the new syntax.
+</p>
+
+<p>
+<a href="/pkg/sort/">Package sort</a>'s <code>IntArray</code> type has been
+renamed to <a href="/pkg/sort/#IntSlice">IntSlice</a>, and similarly for
+<a href="/pkg/sort/#Float64Slice">Float64Slice</a> and
+<a href="/pkg/sort/#StringSlice">StringSlice</a>.
+</p>
+
+<p>
+<a href="/pkg/strings/">Package strings</a>'s <code>Split</code> function has
+itself been split into <a href="/pkg/strings/#Split">Split</a> and
+<a href="/pkg/strings/#SplitN">SplitN</a>.
+<code>SplitN</code> is the same as the old <code>Split</code>.
+The new <code>Split</code> is equivalent to <code>SplitN</code> with a final
+argument of -1.
+</p>
+
+<a href="/pkg/image/draw/">Package image/draw</a>'s
+<a href="/pkg/image/draw/#Draw">Draw</a> function now takes an additional
+argument, a compositing operator.
+If in doubt, use <a href="/pkg/image/draw/#Op">draw.Over</a>.
+</p>
+
+<h3 id="r59.cmd">Tools</h3>
+
+<p>
+<a href="/cmd/goinstall/">Goinstall</a> now installs packages and commands from
+arbitrary remote repositories (not just Google Code, Github, and so on).
+See the <a href="/cmd/goinstall/">goinstall documentation</a> for details.
+</p>
+
+<h2 id="r58">r58 (released 2011/06/29)</h2>
+
+<p>
+The r58 release corresponds to

+</p>
+
+<h3 id="r58.lang">Language</h3>
+
+<p>
+This release fixes a <a href="//golang.org/change/b720749486e1">use of uninitialized memory in programs that misuse <code>goto</code></a>.

+<p>
+As usual, <a href="/cmd/gofix/">gofix</a> will handle the bulk of the rewrites
+necessary for these changes to package APIs.
+</p>
+
+<p>
+<a href="/pkg/http/">Package http</a> drops the <code>finalURL</code> return
+value from the <a href="/pkg/http/#Client.Get">Client.Get</a> method. The value
+is now available via the new <code>Request</code> field on <a
+href="/pkg/http/#Response">http.Response</a>.
+Most instances of the type map[string][]string in have been
+replaced with the new <a href="/pkg/http/#Values">Values</a> type.
+</p>
+
+<p>
+<a href="/pkg/exec/">Package exec</a> has been redesigned with a more
+convenient and succinct API.
+</p>
+
+<p>
+<a href="/pkg/strconv/">Package strconv</a>'s <a href="/pkg/strconv/#Quote">Quote</a>
+function now escapes only those Unicode code points not classified as printable
+by <a href="/pkg/unicode/#IsPrint">unicode.IsPrint</a>.
+Previously Quote would escape all non-ASCII characters.
+This also affects the <a href="/pkg/fmt/">fmt</a> package's <code>"%q"</code>
+formatting directive. The previous quoting behavior is still available via
+strconv's new <a href="/pkg/strconv/#QuoteToASCII">QuoteToASCII</a> function.   
+</p>
+
+<p>
+<a href="/pkg/os/signal/">Package os/signal</a>'s
+<a href="/pkg/os/#Signal">Signal</a> and 
+<a href="/pkg/os/#UnixSignal">UnixSignal</a> types have been moved to the
+<a href="/pkg/os/">os</a> package.
+</p>
+
+<p>
+<a href="/pkg/image/draw/">Package image/draw</a> is the new name for
+<code>exp/draw</code>. The GUI-related code from <code>exp/draw</code> is now
+located in the <a href="/pkg/exp/gui/">exp/gui</a> package.
+</p>
+
+<h3 id="r58.cmd">Tools</h3>
+
+<p>
+<a href="/cmd/goinstall/">Goinstall</a> now observes the GOPATH environment
+variable to build and install your own code and external libraries outside of
+the Go tree (and avoid writing Makefiles).
+</p>
+
+
+<h3 id="r58.minor">Minor revisions</h3>
+
+<p>r58.1 adds 
+<a href="//golang.org/change/293c25943586">build</a> and
+<a href="//golang.org/change/bf17e96b6582">runtime</a>
+changes to make Go run on OS X 10.7 Lion.
+</p>
+
+<h2 id="r57">r57 (released 2011/05/03)</h2>
+
+<p>
+The r57 release corresponds to 
+<code><a href="weekly.html#2011-04-27">weekly.2011-04-27</a></code>
+with additional bug fixes.
+This section highlights the most significant changes in this release.

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

-<h2 id="introduction">Introduction</h2>
-
-<p>
-The Go ecosystem provides a large suite of APIs and tools to
-diagnose logic and performance problems in Go programs. This page
-summarizes the available tools and helps Go users pick the right one
-for their specific problem.
-</p>
-
-<p>
-Diagnostics solutions can be categorized into the following groups:
-</p>
-
-<ul>
-<li><strong>Profiling</strong>: Profiling tools analyze the complexity and costs of a
-Go program such as its memory usage and frequently called
-functions to identify the expensive sections of a Go program.</li>
-<li><strong>Tracing</strong>: Tracing is a way to instrument code to analyze latency
-throughout the lifecycle of a call or user request. Traces provide an
-overview of how much latency each component contributes to the overall
-latency in a system. Traces can span multiple Go processes.</li>
-<li><strong>Debugging</strong>: Debugging allows us to pause a Go program and examine
-its execution. Program state and flow can be verified with debugging.</li>
-<li><strong>Runtime statistics and events</strong>: Collection and analysis of runtime stats and events
-provides a high-level overview of the health of Go programs. Spikes/dips of metrics
-helps us to identify changes in throughput, utilization, and performance.</li>
-</ul>
-
-<p>
-Note: Some diagnostics tools may interfere with each other. For example, precise
-memory profiling skews CPU profiles and goroutine blocking profiling affects scheduler
-trace. Use tools in isolation to get more precise info.
-</p>
-
-<h2 id="profiling">Profiling</h2>
-
-<p>
-Profiling is useful for identifying expensive or frequently called sections
-of code. The Go runtime provides <a href="https://golang.org/pkg/runtime/pprof/">
-profiling data</a> in the format expected by the
-<a href="https://github.com/google/pprof/blob/master/doc/README.md">pprof visualization tool</a>.
-The profiling data can be collected during testing
-via <code>go</code> <code>test</code> or endpoints made available from the <a href="/pkg/net/http/pprof/">
-net/http/pprof</a> package. Users need to collect the profiling data and use pprof tools to filter
-and visualize the top code paths.
-</p>
-
-<p>Predefined profiles provided by the <a href="/pkg/runtime/pprof">runtime/pprof</a> package:</p>
-
-<ul>
-<li>
-<strong>cpu</strong>: CPU profile determines where a program spends
-its time while actively consuming CPU cycles (as opposed to while sleeping or waiting for I/O).
-</li>
-<li>
-<strong>heap</strong>: Heap profile reports memory allocation samples;
-used to monitor current and historical memory usage, and to check for memory leaks.
-</li>
-<li>
-<strong>threadcreate</strong>: Thread creation profile reports the sections
-of the program that lead the creation of new OS threads.
-</li>
-<li>
-<strong>goroutine</strong>: Goroutine profile reports the stack traces of all current goroutines.
-</li>
-<li>
-<strong>block</strong>: Block profile shows where goroutines block waiting on synchronization
-primitives (including timer channels). Block profile is not enabled by default;
-use <code>runtime.SetBlockProfileRate</code> to enable it.
-</li>
-<li>
-<strong>mutex</strong>: Mutex profile reports the lock contentions. When you think your
-CPU is not fully utilized due to a mutex contention, use this profile. Mutex profile
-is not enabled by default, see <code>runtime.SetMutexProfileFraction</code> to enable it.
-</li>
-</ul>
-
-
-<p><strong>What other profilers can I use to profile Go programs?</strong></p>
-
-<p>
-On Linux, <a href="https://perf.wiki.kernel.org/index.php/Tutorial">perf tools</a>
-can be used for profiling Go programs. Perf can profile
-and unwind cgo/SWIG code and kernel, so it can be useful to get insights into
-native/kernel performance bottlenecks. On macOS,
-<a href="https://developer.apple.com/library/content/documentation/DeveloperTools/Conceptual/InstrumentsUserGuide/">Instruments</a>
-suite can be used profile Go programs.
-</p>
-
-<p><strong>Can I profile my production services?</strong></p>
-
-<p>Yes. It is safe to profile programs in production, but enabling
-some profiles (e.g. the CPU profile) adds cost. You should expect to
-see performance downgrade. The performance penalty can be estimated
-by measuring the overhead of the profiler before turning it on in
-production.
-</p>
-
-<p>
-You may want to periodically profile your production services.
-Especially in a system with many replicas of a single process, selecting
-a random replica periodically is a safe option.
-Select a production process, profile it for
-X seconds for every Y seconds and save the results for visualization and
-analysis; then repeat periodically. Results may be manually and/or automatically
-reviewed to find problems.
-Collection of profiles can interfere with each other,
-so it is recommended to collect only a single profile at a time.
-</p>
-
-<p>
-<strong>What are the best ways to visualize the profiling data?</strong>
-</p>
-
-<p>
-The Go tools provide text, graph, and <a href="http://valgrind.org/docs/manual/cl-manual.html">callgrind</a>

-</p>
-
-<p><strong>Can I serve the profiler handlers (/debug/pprof/...) on a different path and port?</strong></p>
-
-<p>
-Yes. The <code>net/http/pprof</code> package registers its handlers to the default
-mux by default, but you can also register them yourself by using the handlers
-exported from the package.
-</p>
-
-<p>
-For example, the following example will serve the pprof.Profile

-
-<p>

-package main
-

-	"net/http/pprof"
-)
-

-<h2 id="tracing">Tracing</h2>
-
-<p>
-Tracing is a way to instrument code to analyze latency throughout the
-lifecycle of a chain of calls. Go provides
-<a href="https://godoc.org/golang.org/x/net/trace">golang.org/x/net/trace</a>
-package as a minimal tracing backend per Go node and provides a minimal
-instrumentation library with a simple dashboard. Go also provides
-an execution tracer to trace the runtime events within an interval.
-</p>
-
-<p>Tracing enables us to:</p>
-
-<ul>
-<li>Instrument and analyze application latency in a Go process.</li>
-<li>Measure the cost of specific calls in a long chain of calls.</li>
-<li>Figure out the utilization and performance improvements.
-Bottlenecks are not always obvious without tracing data.</li>
-</ul>
-
-<p>
-In monolithic systems, it's relatively easy to collect diagnostic data
-from the building blocks of a program. All modules live within one
-process and share common resources to report logs, errors, and other
-diagnostic information. Once your system grows beyond a single process and
-starts to become distributed, it becomes harder to follow a call starting
-from the front-end web server to all of its back-ends until a response is
-returned back to the user. This is where distributed tracing plays a big
-role to instrument and analyze your production systems.
-</p>
-
-<p>
-Distributed tracing is a way to instrument code to analyze latency throughout
-the lifecycle of a user request. When a system is distributed and when
-conventional profiling and debugging tools don’t scale, you might want
-to use distributed tracing tools to analyze the performance of your user
-requests and RPCs.
-</p>
-
-<p>Distributed tracing enables us to:</p>
-
-<ul>
-<li>Instrument and profile application latency in a large system.</li>
-<li>Track all RPCs within the lifecycle of a user request and see integration issues
-that are only visible in production.</li>
-<li>Figure out performance improvements that can be applied to our systems.
-Many bottlenecks are not obvious before the collection of tracing data.</li>
-</ul>
-
-<p>The Go ecosystem provides various distributed tracing libraries per tracing system
-and backend-agnostic ones.</p>
-
-
-<p><strong>Is there a way to automatically intercept each function call and create traces?</strong></p>
-
-<p>
-Go doesn’t provide a way to automatically intercept every function call and create
-trace spans. You need to manually instrument your code to create, end, and annotate spans.
-</p>
-
-<p><strong>How should I propagate trace headers in Go libraries?</strong></p>
-
-<p>
-You can propagate trace identifiers and tags in the
-<a href="/pkg/context#Context"><code>context.Context</code></a>.
-There is no canonical trace key or common representation of trace headers
-in the industry yet. Each tracing provider is responsible for providing propagation
-utilities in their Go libraries.
-</p>
-
-<p>
-<strong>What other low-level events from the standard library or
-runtime can be included in a trace?</strong>
-</p>
-
-<p>
-The standard library and runtime are trying to expose several additional APIs
-to notify on low level internal events. For example,
-<a href="/pkg/net/http/httptrace#ClientTrace"><code>httptrace.ClientTrace</code></a>
-provides APIs to follow low-level events in the life cycle of an outgoing request.
-There is an ongoing effort to retrieve low-level runtime events from
-the runtime execution tracer and allow users to define and record their user events.
-</p>
-
-<h2 id="debugging">Debugging</h2>
-
-<p>
-Debugging is the process of identifying why a program misbehaves.
-Debuggers allow us to understand a program’s execution flow and current state.
-There are several styles of debugging; this section will only focus on attaching
-a debugger to a program and core dump debugging.
-</p>
-
-<p>Go users mostly use the following debuggers:</p>
-
-<ul>
-<li>
-<a href="https://github.com/derekparker/delve">Delve</a>:
-Delve is a debugger for the Go programming language. It has
-support for Go’s runtime concepts and built-in types. Delve is
-trying to be a fully featured reliable debugger for Go programs.
-</li>
-<li>
-<a href="https://golang.org/doc/gdb">GDB</a>:
-Go provides GDB support via the standard Go compiler and Gccgo.
-The stack management, threading, and runtime contain aspects that differ
-enough from the execution model GDB expects that they can confuse the
-debugger, even when the program is compiled with gccgo. Even though
-GDB can be used to debug Go programs, it is not ideal and may
-create confusion.
-</li>
-</ul>
-
-<p><strong>How well do debuggers work with Go programs?</strong></p>
-
-<p>
-The <code>gc</code> compiler performs optimizations such as
-function inlining and variable registerization. These optimizations
-sometimes make debugging with debuggers harder. There is an ongoing
-effort to improve the quality of the DWARF information generated for
-optimized binaries. Until those improvements are available, we recommend
-disabling optimizations when building the code being debugged. The following
-command builds a package with no compiler optimizations:
-
-<p>
-<pre>
-$ go build -gcflags=all="-N -l"
-</pre>
-</p>
-
-As part of the improvement effort, Go 1.10 introduced a new compiler
-flag <code>-dwarflocationlists</code>. The flag causes the compiler to
-add location lists that helps debuggers work with optimized binaries.
-The following command builds a package with optimizations but with
-the DWARF location lists:
-
-<p>
-<pre>
-$ go build -gcflags="-dwarflocationlists=true"
-</pre>
-</p>
-
-<p><strong>What’s the recommended debugger user interface?</strong></p>
-
-<p>
-Even though both delve and gdb provides CLIs, most editor integrations
-and IDEs provides debugging-specific user interfaces.
-</p>
-
-<p><strong>Is it possible to do postmortem debugging with Go programs?</strong></p>
-
-<p>
-A core dump file is a file that contains the memory dump of a running
-process and its process status. It is primarily used for post-mortem
-debugging of a program and to understand its state
-while it is still running. These two cases make debugging of core
-dumps a good diagnostic aid to postmortem and analyze production
-services. It is possible to obtain core files from Go programs and
-use delve or gdb to debug, see the
-<a href="https://golang.org/wiki/CoreDumpDebugging">core dump debugging</a>
-page for a step-by-step guide.
-</p>
-
-<h2 id="runtime">Runtime statistics and events</h2>
-
-<p>
-The runtime provides stats and reporting of internal events for
-users to diagnose performance and utilization problems at the
-runtime level.
-</p>
-
-<p>
-Users can monitor these stats to better understand the overall
-health and performance of Go programs.
-Some frequently monitored stats and states:
-</p>
-
-<ul>
-<li><code><a href="/pkg/runtime/#ReadMemStats">runtime.ReadMemStats</a></code>
-reports the metrics related to heap
-allocation and garbage collection. Memory stats are useful for
-monitoring how much memory resources a process is consuming,
-whether the process can utilize memory well, and to catch
-memory leaks.</li>
-<li><code><a href="/pkg/runtime/debug/#ReadGCStats">debug.ReadGCStats</a></code>
-reads statistics about garbage collection.
-It is useful to see how much of the resources are spent on GC pauses.
-It also reports a timeline of garbage collector pauses and pause time percentiles.</li>
-<li><code><a href="/pkg/runtime/debug/#Stack">debug.Stack</a></code>
-returns the current stack trace. Stack trace
-is useful to see how many goroutines are currently running,
-what they are doing, and whether they are blocked or not.</li>
-<li><code><a href="/pkg/runtime/debug/#WriteHeapDump">debug.WriteHeapDump</a></code>
-suspends the execution of all goroutines
-and allows you to dump the heap to a file. A heap dump is a
-snapshot of a Go process' memory at a given time. It contains all
-allocated objects as well as goroutines, finalizers, and more.</li>
-<li><code><a href="/pkg/runtime#NumGoroutine">runtime.NumGoroutine</a></code>
-returns the number of current goroutines.
-The value can be monitored to see whether enough goroutines are
-utilized, or to detect goroutine leaks.</li>
-</ul>
-
-<h3 id="execution-tracer">Execution tracer</h3>
-
-<p>Go comes with a runtime execution tracer to capture a wide range
-of runtime events. Scheduling, syscall, garbage collections,
-heap size, and other events are collected by runtime and available
-for visualization by the go tool trace. Execution tracer is a tool
-to detect latency and utilization problems. You can examine how well
-the CPU is utilized, and when networking or syscalls are a cause of
-preemption for the goroutines.</p>
-
-<p>Tracer is useful to:</p>
-<ul>
-<li>Understand how your goroutines execute.</li>
-<li>Understand some of the core runtime events such as GC runs.</li>
-<li>Identify poorly parallelized execution.</li>
-</ul>
-
-<p>However, it is not great for identifying hot spots such as
-analyzing the cause of excessive memory or CPU usage.
-Use profiling tools instead first to address them.</p>
-
-<p>
-<img width="800" src="https://storage.googleapis.com/golangorg-assets/tracer-lock.png">
-</p>
-
-<p>Above, the go tool trace visualization shows the execution started
-fine, and then it became serialized. It suggests that there might
-be lock contention for a shared resource that creates a bottleneck.</p>
-
-<p>See <a href="https://golang.org/cmd/trace/"><code>go</code> <code>tool</code> <code>trace</code></a>
-to collect and analyze runtime traces.
-</p>
-
-<h3 id="godebug">GODEBUG</h3>
-
-<p>Runtime also emits events and information if
-<a href="https://golang.org/pkg/runtime/#hdr-Environment_Variables">GODEBUG</a>
-environmental variable is set accordingly.</p>
-
-<ul>
-<li>GODEBUG=gctrace=1 prints garbage collector events at
-each collection, summarizing the amount of memory collected
-and the length of the pause.</li>
-<li>GODEBUG=schedtrace=X prints scheduling events every X milliseconds.</li>
-</ul>
-
-<p>The GODEBUG environmental variable can be used to disable use of
-instruction set extensions in the standard library and runtime.</p>
-
-<ul>
-<li>GODEBUG=cpu.all=off disables the use of all optional
-instruction set extensions.</li>
-<li>GODEBUG=cpu.<em>extension</em>=off disables use of instructions from the
-specified instruction set extension.<br>
-<em>extension</em> is the lower case name for the instruction set extension
-such as <em>sse41</em> or <em>avx</em>.</li>

-  Go 1.11 adds an experimental port to <a href="https://webassembly.org">WebAssembly</a>

-</p>
-<p>
-  Go programs currently compile to one WebAssembly module that

-  Binary size and interop with other languages has not yet been a

-<h3 id="modules">Modules, package versioning, and dependency management</h3>
-<p>
-  Go 1.11 adds preliminary support for a <a href="/cmd/go/#hdr-Modules__module_versions__and_more">new concept called “modules,”</a>
-  an alternative to GOPATH with integrated support for versioning and
-  package distribution.
-  Using modules, developers are no longer confined to working inside GOPATH,
-  version dependency information is explicit yet lightweight,
-  and builds are more reliable and reproducible.
-</p>
-
-<p>
-  Module support is considered experimental.
-  Details are likely to change in response to feedback from Go 1.11 users,
-  and we have more tools planned.
-  Although the details of module support may change, projects that convert
-  to modules using Go 1.11 will continue to work with Go 1.12 and later.
-  If you encounter bugs using modules,
-  please <a href="https://golang.org/issue/new">file issues</a>
-  so we can fix them. For more information, see the
-  <a href="/cmd/go#hdr-Modules__module_versions__and_more"><code>go</code> command documentation</a>.
-</p>
-
-<h3 id="importpath">Import path restriction</h3>
-
-<p>
-  Because Go module support assigns special meaning to the
-  <code>@</code> symbol in command line operations,
-  the <code>go</code> command now disallows the use of
-  import paths containing <code>@</code> symbols.
-  Such import paths were never allowed by <code>go</code> <code>get</code>,
-  so this restriction can only affect users building
-  custom GOPATH trees by other means.
-</p>
-
-<h3 id="gopackages">Package loading</h3>
-
-<p>
-  The new package
-  <a href="https://godoc.org/golang.org/x/tools/go/packages"><code>golang.org/x/tools/go/packages</code></a>
-  provides a simple API for locating and loading packages of Go source code.
-  Although not yet part of the standard library, for many tasks it
-  effectively replaces the <a href="/pkg/go/build"><code>go/build</code></a>
-  package, whose API is unable to fully support modules.
-  Because it runs an external query command such as
-  <a href="/cmd/go/#hdr-List_packages"><code>go list</code></a>
-  to obtain information about Go packages, it enables the construction of
-  analysis tools that work equally well with alternative build systems
-  such as <a href="https://bazel.build">Bazel</a>
-  and <a href="https://buckbuild.com">Buck</a>.
-</p>
-
-<h3 id="gocache">Build cache requirement</h3>
-

-  Go 1.11 will be the last release to support setting the environment
-  variable <code>GOCACHE=off</code> to disable the
-  <a href="/cmd/go/#hdr-Build_and_test_caching">build cache</a>,
-  introduced in Go 1.10.
-  Starting in Go 1.12, the build cache will be required,
-  as a step toward eliminating <code>$GOPATH/pkg</code>.
-  The module and package loading support described above
-  already require that the build cache be enabled.
-  If you have disabled the build cache to avoid problems you encountered,
-  please <a href="https://golang.org/issue/new">file an issue</a> to let us know about them.

-Since Go 1.10, cgo has translated some C pointer types to the Go

-the <code>CFTypeRef</code> hierarchy in Darwin's CoreFoundation
-framework and the <code>jobject</code> hierarchy in Java's JNI
-interface. In Go 1.11, several improvements have been made to the code
-that detects these types. Code that uses these types may need some
-updating. See the <a href="go1.10.html#cgo">Go 1.10 release notes</a> for

-<h3 id="go_command">Go command</h3>
-
-<p><!-- CL 126656 -->
-  The environment variable <code>GOFLAGS</code> may now be used
-  to set default flags for the <code>go</code> command.
-  This is useful in certain situations.
-  Linking can be noticeably slower on underpowered systems due to DWARF,
-  and users may want to set <code>-ldflags=-w</code> by default.
-  For modules, some users and CI systems will want vendoring always,
-  so they should set <code>-mod=vendor</code> by default.
-  For more information, see the <a href="/cmd/go/#hdr-Environment_variables"><code>go</code>
-  command documentation</a>.
-</p>
-
-<h3 id="godoc">Godoc</h3>
-
-<p>
-  Go 1.11 will be the last release to support <code>godoc</code>'s command-line interface.
-  In future releases, <code>godoc</code> will only be a web server. Users should use
-  <code>go</code> <code>doc</code> for command-line help output instead.
-</p>
-
-<p><!-- CL 85396, CL 124495 -->
-  The <code>godoc</code> web server now shows which version of Go introduced
-  new API features. The initial Go version of types, funcs, and methods are shown
-  right-aligned. For example, see <a href="/pkg/os/#UserCacheDir"><code>UserCacheDir</code></a>, with "1.11"
-  on the right side. For struct fields, inline comments are added when the struct field was
-  added in a Go version other than when the type itself was introduced.
-  For a struct field example, see
-  <a href="/pkg/net/http/httptrace/#ClientTrace.Got1xxResponse"><code>ClientTrace.Got1xxResponse</code></a>.
-</p>
-
-<h3 id="gofmt">Gofmt</h3>
-
-<p>
-  One minor detail of the default formatting of Go source code has changed.
-  When formatting expression lists with inline comments, the comments were
-  aligned according to a heuristic.
-  However, in some cases the alignment would be split up too easily, or
-  introduce too much whitespace.
-  The heuristic has been changed to behave better for human-written code.
-</p>
-
-<p>
-  Note that these kinds of minor updates to gofmt are expected from time to
-  time.
-  In general, systems that need consistent formatting of Go source code should
-  use a specific version of the <code>gofmt</code> binary.
-  See the <a href="/pkg/go/format/">go/format</a> package documentation for more
-  information.

-  The <a href="/cmd/go/"><code>go</code>&nbsp;<code>run</code></a>

-  This allows <code>go</code>&nbsp;<code>run</code>&nbsp;<code>pkg</code> or <code>go</code>&nbsp;<code>run</code>&nbsp;<code>dir</code>, most importantly <code>go</code>&nbsp;<code>run</code>&nbsp;<code>.</code>
-</p>
-
-<h2 id="runtime">Runtime</h2>
-
-<p><!-- CL 85887 -->
-  The runtime now uses a sparse heap layout so there is no longer a
-  limit to the size of the Go heap (previously, the limit was 512GiB).
-  This also fixes rare "address space conflict" failures in mixed Go/C
-  binaries or binaries compiled with <code>-race</code>.
-</p>
-
-<p><!-- CL 108679, CL 106156 -->
-  On macOS and iOS, the runtime now uses <code>libSystem.dylib</code> instead of
-  calling the kernel directly. This should make Go binaries more
-  compatible with future versions of macOS and iOS.
-  The <a href="/pkg/syscall">syscall</a> package still makes direct
-  system calls; fixing this is planned for a future release.

-
-<h2 id="performance">Performance</h2>
-
-<p>
-As always, the changes are so general and varied that precise

-optimizations in the core library.
-</p>

-
-<p><!-- CL 109517 -->
-  The compiler now optimizes slice extension of the form

-</p>
-
-<p><!-- CL 100277, CL 105635, CL 109776 -->
-  The compiler now performs significantly more aggressive bounds-check
-  and branch elimination. Notably, it now recognizes transitive
-  relations, so if <code>i&lt;j</code> and <code>j&lt;len(s)</code>,
-  it can use these facts to eliminate the bounds check
-  for <code>s[i]</code>. It also understands simple arithmetic such
-  as <code>s[i-10]</code> and can recognize more inductive cases in
-  loops. Furthermore, the compiler now uses bounds information to more
-  aggressively optimize shift operations.

-<h2 id="introduction">Introduction to Go 1.12</h2>
-
-<p>
-  The latest Go release, version 1.12, arrives six months after <a href="go1.11">Go 1.11</a>.
-  Most of its changes are in the implementation of the toolchain, runtime, and libraries.
-  As always, the release maintains the Go 1 <a href="/doc/go1compat">promise of compatibility</a>.
-  We expect almost all Go programs to continue to compile and run as before.
-</p>
-
-<h2 id="language">Changes to the language</h2>
-
-<p>
-  There are no changes to the language specification.
-</p>
-
-<h2 id="ports">Ports</h2>
-
-<p><!-- CL 138675 -->
-  The race detector is now supported on <code>linux/arm64</code>.
-</p>
-
-<p id="freebsd">
-  Go 1.12 is the last release that is supported on FreeBSD 10.x, which has
-  already reached end-of-life. Go 1.13 will require FreeBSD 11.2+ or FreeBSD
-  12.0+.
-  FreeBSD 12.0+ requires a kernel with the COMPAT_FREEBSD11 option set (this is the default).

-  <code>hurd</code> is now a recognized value for <code>GOOS</code>, reserved
-  for the GNU/Hurd system for use with <code>gccgo</code>.
-</p>
-
-<h3 id="windows">Windows</h3>
-
-<p>
-  Go's new <code>windows/arm</code> port supports running Go on Windows 10
-  IoT Core on 32-bit ARM chips such as the Raspberry Pi 3.
-</p>
-
-<h3 id="aix">AIX</h3>
-
-<p>
-  Go now supports AIX 7.2 and later on POWER8 architectures (<code>aix/ppc64</code>). External linking, cgo, pprof and the race detector aren't yet supported.
-</p>
-
-<h3 id="darwin">Darwin</h3>
-
-<p>
-  Go 1.12 is the last release that will run on macOS 10.10 Yosemite.
-  Go 1.13 will require macOS 10.11 El Capitan or later.
-</p>
-
-<p><!-- CL 141639 -->
-  <code>libSystem</code> is now used when making syscalls on Darwin,
-  ensuring forward-compatibility with future versions of macOS and iOS.
-  <!-- CL 153338 -->
-  The switch to <code>libSystem</code> triggered additional App Store
-  checks for private API usage. Since it is considered private,
-  <code>syscall.Getdirentries</code> now always fails with
-  <code>ENOSYS</code> on iOS.
-  Additionally, <a href="/pkg/syscall/#Setrlimit"><code>syscall.Setrlimit</code></a>
-  reports <code>invalid</code> <code>argument</code> in places where it historically
-  succeeded. These consequences are not specific to Go and users should expect
-  behavioral parity with <code>libSystem</code>'s implementation going forward.
-</p>
-
-<h2 id="tools">Tools</h2>
-
-<h3 id="vet"><code>go tool vet</code> no longer supported</h3>
-
-<p>
-  The <code>go vet</code> command has been rewritten to serve as the
-  base for a range of different source code analysis tools. See
-  the <a href="https://godoc.org/golang.org/x/tools/go/analysis">golang.org/x/tools/go/analysis</a>
-  package for details. A side-effect is that <code>go tool vet</code>
-  is no longer supported. External tools that use <code>go tool
-  vet</code> must be changed to use <code>go
-  vet</code>. Using <code>go vet</code> instead of <code>go tool
-  vet</code> should work with all supported versions of Go.
-</p>
-
-<p>
-  As part of this change, the experimental <code>-shadow</code> option
-  is no longer available with <code>go vet</code>. Checking for
-  variable shadowing may now be done using
-<pre>
-go get -u golang.org/x/tools/go/analysis/passes/shadow/cmd/shadow
-go vet -vettool=$(which shadow)
-</pre>
-</p>
-
-<h3 id="tour">Tour</h3>
-
-<p> <!-- CL 152657 -->
-The Go tour is no longer included in the main binary distribution. To
-run the tour locally, instead of running <code>go</code> <code>tool</code> <code>tour</code>,
-manually install it:
-<pre>
-go get -u golang.org/x/tour
-tour
-</pre>
-</p>
-
-<h3 id="gocache">Build cache requirement</h3>
-
-<p>
-  The <a href="/cmd/go/#hdr-Build_and_test_caching">build cache</a> is now
-  required as a step toward eliminating
-  <code>$GOPATH/pkg</code>. Setting the environment variable
-  <code>GOCACHE=off</code> will cause <code>go</code> commands that write to the
-  cache to fail.
-</p>
-
-<h3 id="binary-only">Binary-only packages</h3>
-
-<p>
-  Go 1.12 is the last release that will support binary-only packages.
-</p>
-
-<h3 id="cgo">Cgo</h3>
-
-<p>
-	Go 1.12 will translate the C type <code>EGLDisplay</code> to the Go type <code>uintptr</code>.
-	This change is similar to how Go 1.10 and newer treats Darwin's CoreFoundation
-	and Java's JNI types. See the
-	<a href="/cmd/cgo/#hdr-Special_cases">cgo documentation</a>
-	for more information.
-</p>
-
-<p><!-- CL 152657 -->
-  Mangled C names are no longer accepted in packages that use Cgo. Use the Cgo
-  names instead. For example, use the documented cgo name <code>C.char</code>
-  rather than the mangled name <code>_Ctype_char</code> that cgo generates.
-</p>
-
-<h3 id="modules">Modules</h3>
-
-<p><!-- CL 148517 -->
-  When <code>GO111MODULE</code> is set to <code>on</code>, the <code>go</code>
-  command now supports module-aware operations outside of a module directory,
-  provided that those operations do not need to resolve import paths relative to
-  the current directory or explicitly edit the <code>go.mod</code> file.
-  Commands such as <code>go</code> <code>get</code>,
-  <code>go</code> <code>list</code>, and
-  <code>go</code> <code>mod</code> <code>download</code> behave as if in a
-  module with initially-empty requirements.
-  In this mode, <code>go</code> <code>env</code> <code>GOMOD</code> reports
-  the system's null device (<code>/dev/null</code> or <code>NUL</code>).
-</p>
-
-<p><!-- CL 146382 -->
-  <code>go</code> commands that download and extract modules are now safe to
-  invoke concurrently.
-  The module cache (<code>GOPATH/pkg/mod</code>) must reside in a filesystem that
-  supports file locking.
-</p>
-
-<p><!-- CL 147282, 147281 -->
-  The <code>go</code> directive in a <code>go.mod</code> file now indicates the
-  version of the language used by the files within that module.
-  It will be set to the current release
-  (<code>go</code> <code>1.12</code>) if no existing version is
-  present.
-  If the <code>go</code> directive for a module specifies a
-  version <em>newer</em> than the toolchain in use, the <code>go</code> command
-  will attempt to build the packages regardless, and will note the mismatch only if
-  that build fails.
-</p>
-
-<p><!-- CL 147282, 147281 -->
-  This changed use of the <code>go</code> directive means that if you
-  use Go 1.12 to build a module, thus recording <code>go 1.12</code>
-  in the <code>go.mod</code> file, you will get an error when
-  attempting to build the same module with Go 1.11 through Go 1.11.3.
-  Go 1.11.4 or later will work fine, as will releases older than Go 1.11.
-  If you must use Go 1.11 through 1.11.3, you can avoid the problem by
-  setting the language version to 1.11, using the Go 1.12 go tool,
-  via <code>go mod edit -go=1.11</code>.
-</p>
-
-<p><!-- CL 152739 -->
-  When an import cannot be resolved using the active modules,
-  the <code>go</code> command will now try to use the modules mentioned in the
-  main module's <code>replace</code> directives before consulting the module
-  cache and the usual network sources.
-  If a matching replacement is found but the <code>replace</code> directive does
-  not specify a version, the <code>go</code> command uses a pseudo-version
-  derived from the zero <code>time.Time</code> (such
-  as <code>v0.0.0-00010101000000-000000000000</code>).
-</p>
-
-<h3 id="compiler">Compiler toolchain</h3>
-
-<p><!-- CL 134155, 134156 -->
-  The compiler's live variable analysis has improved. This may mean that
-  finalizers will be executed sooner in this release than in previous
-  releases. If that is a problem, consider the appropriate addition of a
-  <a href="/pkg/runtime/#KeepAlive"><code>runtime.KeepAlive</code></a> call.
-</p>
-
-<p><!-- CL 147361 -->
-  More functions are now eligible for inlining by default, including
-  functions that do nothing but call another function.
-  This extra inlining makes it additionally important to use
-  <a href="/pkg/runtime/#CallersFrames"><code>runtime.CallersFrames</code></a>
-  instead of iterating over the result of
-  <a href="/pkg/runtime/#Callers"><code>runtime.Callers</code></a> directly.
-<pre>
-// Old code which no longer works correctly (it will miss inlined call frames).
-var pcs [10]uintptr
-n := runtime.Callers(1, pcs[:])
-for _, pc := range pcs[:n] {
-	f := runtime.FuncForPC(pc)
-	if f != nil {
-		fmt.Println(f.Name())
-	}
-}
-</pre>
-<pre>
-// New code which will work correctly.
-var pcs [10]uintptr
-n := runtime.Callers(1, pcs[:])
-frames := runtime.CallersFrames(pcs[:n])
-for {
-	frame, more := frames.Next()
-	fmt.Println(frame.Function)
-	if !more {
-		break
-	}
-}
-</pre>
-</p>
-
-<p><!-- CL 153477 -->
-  Wrappers generated by the compiler to implement method expressions
-  are no longer reported
-  by <a href="/pkg/runtime/#CallersFrames"><code>runtime.CallersFrames</code></a>
-  and <a href="/pkg/runtime/#Stack"><code>runtime.Stack</code></a>. They
-  are also not printed in panic stack traces.
-
-  This change aligns the <code>gc</code> toolchain to match
-  the <code>gccgo</code> toolchain, which already elided such wrappers
-  from stack traces.
-
-  Clients of these APIs might need to adjust for the missing
-  frames. For code that must interoperate between 1.11 and 1.12
-  releases, you can replace the method expression <code>x.M</code>
-  with the function literal <code>func (...) { x.M(...) } </code>.
-</p>
-
-<p><!-- CL 144340 -->
-  The compiler now accepts a <code>-lang</code> flag to set the Go language
-  version to use. For example, <code>-lang=go1.8</code> causes the compiler to
-  emit an error if the program uses type aliases, which were added in Go 1.9.
-  Language changes made before Go 1.12 are not consistently enforced.
-</p>
-
-<p><!-- CL 147160 -->
-  The compiler toolchain now uses different conventions to call Go
-  functions and assembly functions. This should be invisible to users,
-  except for calls that simultaneously cross between Go and
-  assembly <em>and</em> cross a package boundary. If linking results
-  in an error like "relocation target not defined for ABIInternal (but
-  is defined for ABI0)", please refer to the
-  <a href="https://github.com/golang/proposal/blob/master/design/27539-internal-abi.md#compatibility">compatibility section</a>
-  of the ABI design document.
-</p>
-
-<p><!-- CL 145179 -->
-  There have been many improvements to the DWARF debug information
-  produced by the compiler, including improvements to argument
-  printing and variable location information.
-</p>
-
-<p><!-- CL 61511 -->
-  Go programs now also maintain stack frame pointers on <code>linux/arm64</code>
-  for the benefit of profiling tools like <code>perf</code>. The frame pointer
-  maintenance has a small run-time overhead that varies but averages around 3%.
-  To build a toolchain that does not use frame pointers, set
-  <code>GOEXPERIMENT=noframepointer</code> when running <code>make.bash</code>.
-</p>
-
-<p><!-- CL 142717 -->
-  The obsolete "safe" compiler mode (enabled by the <code>-u</code> gcflag) has been removed.
-</p>
-
-<h3 id="godoc"><code>godoc</code> and <code>go</code> <code>doc</code></h3>
-
-<p>
-  In Go 1.12, <code>godoc</code> no longer has a command-line interface and
-  is only a web server. Users should use <code>go</code> <code>doc</code>
-  for command-line help output instead. Go 1.12 is the last release that will
-  include the <code>godoc</code> webserver; in Go 1.13 it will be available
-  via <code>go</code> <code>get</code>.
-</p>
-
-<p><!-- CL 141977 -->
-  <code>go</code> <code>doc</code> now supports the <code>-all</code> flag,
-  which will cause it to print all exported APIs and their documentation,
-  as the <code>godoc</code> command line used to do.
-</p>
-
-<p><!-- CL 140959 -->
-  <code>go</code> <code>doc</code> also now includes the <code>-src</code> flag,
-  which will show the target's source code.
-</p>
-
-<h3 id="trace">Trace</h3>
-
-<p><!-- CL 60790 -->
-  The trace tool now supports plotting mutator utilization curves,
-  including cross-references to the execution trace. These are useful
-  for analyzing the impact of the garbage collector on application
-  latency and throughput.
-</p>
-
-<h3 id="assembler">Assembler</h3>
-
-<p><!-- CL 147218 -->
-  On <code>arm64</code>, the platform register was renamed from
-  <code>R18</code> to <code>R18_PLATFORM</code> to prevent accidental
-  use, as the OS could choose to reserve this register.
-</p>
-
-<h2 id="runtime">Runtime</h2>
-
-<p><!-- CL 138959 -->
-  Go 1.12 significantly improves the performance of sweeping when a
-  large fraction of the heap remains live. This reduces allocation
-  latency immediately following a garbage collection.
-</p>
-
-<p><!-- CL 139719 -->
-  The Go runtime now releases memory back to the operating system more
-  aggressively, particularly in response to large allocations that
-  can't reuse existing heap space.
-</p>
-
-<p><!-- CL 146342, CL 146340, CL 146345, CL 146339, CL 146343, CL 146337, CL 146341, CL 146338 -->
-  The Go runtime's timer and deadline code is faster and scales better
-  with higher numbers of CPUs. In particular, this improves the
-  performance of manipulating network connection deadlines.
-</p>
-
-<p><!-- CL 135395 -->
-  On Linux, the runtime now uses <code>MADV_FREE</code> to release unused
-  memory. This is more efficient but may result in higher reported
-  RSS. The kernel will reclaim the unused data when it is needed.
-  To revert to the Go 1.11 behavior (<code>MADV_DONTNEED</code>), set the
-  environment variable <code>GODEBUG=madvdontneed=1</code>.
-</p>
-
-<p><!-- CL 149578 -->
-  Adding cpu.<em>extension</em>=off to the
-  <a href="/doc/diagnostics.html#godebug">GODEBUG</a> environment
-  variable now disables the use of optional CPU instruction
-  set extensions in the standard library and runtime. This is not
-  yet supported on Windows.
-</p>
-
-<p><!-- CL 158337 -->
-  Go 1.12 improves the accuracy of memory profiles by fixing
-  overcounting of large heap allocations.
-</p>
-
-<p><!-- CL 159717 -->
-  Tracebacks, <code>runtime.Caller</code>,
-  and <code>runtime.Callers</code> no longer include
-  compiler-generated initialization functions.  Doing a traceback
-  during the initialization of a global variable will now show a
-  function named <code>PKG.init.ializers</code>.
-</p>
-
-<h2 id="library">Core library</h2>
-
-<h3 id="tls_1_3">TLS 1.3</h3>
-
-<p>
-  Go 1.12 adds opt-in support for TLS 1.3 in the <code>crypto/tls</code> package as
-  specified by <a href="https://www.rfc-editor.org/info/rfc8446">RFC 8446</a>. It can
-  be enabled by adding the value <code>tls13=1</code> to the <code>GODEBUG</code>
-  environment variable. It will be enabled by default in Go 1.13.
-</p>
-
-<p>
-  To negotiate TLS 1.3, make sure you do not set an explicit <code>MaxVersion</code> in
-  <a href="/pkg/crypto/tls/#Config"><code>Config</code></a> and run your program with
-  the environment variable <code>GODEBUG=tls13=1</code> set.
-</p>
-
-<p>
-  All TLS 1.2 features except <code>TLSUnique</code> in
-  <a href="/pkg/crypto/tls/#ConnectionState"><code>ConnectionState</code></a>
-  and renegotiation are available in TLS 1.3 and provide equivalent or
-  better security and performance. Note that even though TLS 1.3 is backwards
-  compatible with previous versions, certain legacy systems might not work
-  correctly when attempting to negotiate it. RSA certificate keys too small
-  to be secure (including 512-bit keys) will not work with TLS 1.3.
-</p>
-
-<p>
-  TLS 1.3 cipher suites are not configurable. All supported cipher suites are
-  safe, and if <code>PreferServerCipherSuites</code> is set in
-  <a href="/pkg/crypto/tls/#Config"><code>Config</code></a> the preference order
-  is based on the available hardware.
-</p>
-
-<p>
-  Early data (also called "0-RTT mode") is not currently supported as a
-  client or server. Additionally, a Go 1.12 server does not support skipping
-  unexpected early data if a client sends it. Since TLS 1.3 0-RTT mode
-  involves clients keeping state regarding which servers support 0-RTT,
-  a Go 1.12 server cannot be part of a load-balancing pool where some other
-  servers do support 0-RTT. If switching a domain from a server that supported
-  0-RTT to a Go 1.12 server, 0-RTT would have to be disabled for at least the
-  lifetime of the issued session tickets before the switch to ensure
-  uninterrupted operation.
-</p>
-
-<p>
-  In TLS 1.3 the client is the last one to speak in the handshake, so if it causes
-  an error to occur on the server, it will be returned on the client by the first
-  <a href="/pkg/crypto/tls/#Conn.Read"><code>Read</code></a>, not by
-  <a href="/pkg/crypto/tls/#Conn.Handshake"><code>Handshake</code></a>. For
-  example, that will be the case if the server rejects the client certificate.
-  Similarly, session tickets are now post-handshake messages, so are only
-  received by the client upon its first
-  <a href="/pkg/crypto/tls/#Conn.Read"><code>Read</code></a>.
-</p>
-
-<h3 id="minor_library_changes">Minor changes to the library</h3>
-

-<h2 id="introduction">Introduction to Go 1.14</h2>
-
-<p>
-  The latest Go release, version 1.14, arrives six months after <a href="go1.13">Go 1.13</a>.
-  Most of its changes are in the implementation of the toolchain, runtime, and libraries.
-  As always, the release maintains the Go 1 <a href="/doc/go1compat.html">promise of compatibility</a>.
-  We expect almost all Go programs to continue to compile and run as before.
-</p>
-
-<p>
-  Module support in the <code>go</code> command is now ready for production use,
-  and we encourage all users to <a href="https://blog.golang.org/migrating-to-go-modules">migrate to Go
-  modules for dependency management</a>. If you are unable to migrate due to a problem in the Go
-  toolchain, please ensure that the problem has an
-  <a href="https://golang.org/issue?q=is%3Aissue+is%3Aopen+label%3Amodules">open issue</a>
-  filed. (If the issue is not on the <code>Go1.15</code> milestone, please let us
-  know why it prevents you from migrating so that we can prioritize it
-  appropriately.)
-</p>
-
-<h2 id="language">Changes to the language</h2>
-
-<p>
-  Per the <a href="https://github.com/golang/proposal/blob/master/design/6977-overlapping-interfaces.md">overlapping interfaces proposal</a>,
-  Go 1.14 now permits embedding of interfaces with overlapping method sets:
-  methods from an embedded interface may have the same names and identical signatures
-  as methods already present in the (embedding) interface. This solves problems that typically
-  (but not exclusively) occur with diamond-shaped embedding graphs.
-  Explicitly declared methods in an interface must remain
-  <a href="https://tip.golang.org/ref/spec#Uniqueness_of_identifiers">unique</a>, as before.
-</p>
-
-<h2 id="ports">Ports</h2>
-
-<h3 id="darwin">Darwin</h3>
-
-<p>
-  Go 1.14 is the last release that will run on macOS 10.11 El Capitan.
-  Go 1.15 will require macOS 10.12 Sierra or later.
-</p>
-
-<p><!-- golang.org/issue/34749 -->
-  Go 1.14 is the last Go release to support 32-bit binaries on
-  macOS (the <code>darwin/386</code> port). They are no longer
-  supported by macOS, starting with macOS 10.15 (Catalina).
-  Go continues to support the 64-bit <code>darwin/amd64</code> port.
-</p>
-
-<p><!-- golang.org/issue/34751 -->
-  Go 1.14 will likely be the last Go release to support 32-bit
-  binaries on iOS, iPadOS, watchOS, and tvOS
-  (the <code>darwin/arm</code> port). Go continues to support the
-  64-bit <code>darwin/arm64</code> port.

-  (Data Execution Prevention)</a> enabled.
-</p>
-
-<p><!-- CL 202439 -->
-  On Windows, creating a file
-  via <a href="/pkg/os#CreateFile"><code>os.OpenFile</code></a> with
-  the <a href="/pkg/os/#O_CREATE"><code>os.O_CREATE</code></a> flag, or
-  via <a href="/pkg/syscall#Open"><code>syscall.Open</code></a> with
-  the <a href="/pkg/syscall#O_CREAT"><code>syscall.O_CREAT</code></a>
-  flag, will now create the file as read-only if the
-  bit <code>0o200</code> (owner write permission) is not set in the
-  permission argument. This makes the behavior on Windows more like
-  that on Unix systems.
-</p>
-
-<h3 id="wasm">WebAssembly</h3>
-
-<p><!-- CL 203600 -->
-  JavaScript values referenced from Go via <code>js.Value</code>
-  objects can now be garbage collected.
-</p>
-
-<p><!-- CL 203600 -->
-  <code>js.Value</code> values can no longer be compared using
-  the <code>==</code> operator, and instead must be compared using
-  their <code>Equal</code> method.
-</p>
-
-<p><!-- CL 203600 -->
-  <code>js.Value</code> now

-
-<p><!-- Issue 27532 -->
-  Go 1.14 contains experimental support for 64-bit RISC-V on Linux
-  (<code>GOOS=linux</code>, <code>GOARCH=riscv64</code>). Be aware
-  that performance, assembly syntax stability, and possibly
-  correctness are a work in progress.
-</p>
-
-<h3 id="freebsd">FreeBSD</h3>
-
-<p><!-- CL 199919 -->
-  Go now supports the 64-bit ARM architecture on FreeBSD 12.0 or later (the

-
-<h3 id="nacl">Native Client (NaCl)</h3>
-
-<p><!-- golang.org/issue/30439 -->
-  As <a href="go1.13#ports">announced</a> in the Go 1.13 release notes,

-
-<h4 id="vendor">Vendoring</h4>
-<!-- golang.org/issue/33848 -->
-
-<p>
-  When the main module contains a top-level <code>vendor</code> directory and
-  its <code>go.mod</code> file specifies <code>go</code> <code>1.14</code> or
-  higher, the <code>go</code> command now defaults to <code>-mod=vendor</code>
-  for operations that accept that flag. A new value for that flag,
-  <code>-mod=mod</code>, causes the <code>go</code> command to instead load
-  modules from the module cache (as when no <code>vendor</code> directory is
-  present).
-</p>
-
-<p>
-  When <code>-mod=vendor</code> is set (explicitly or by default), the
-  <code>go</code> command now verifies that the main module's
-  <code>vendor/modules.txt</code> file is consistent with its
-  <code>go.mod</code> file.
-</p>
-
-<p>
-  <code>go</code> <code>list</code> <code>-m</code> no longer silently omits
-  transitive dependencies that do not provide packages in
-  the <code>vendor</code> directory. It now fails explicitly if
-  <code>-mod=vendor</code> is set and information is requested for a module not
-  mentioned in <code>vendor/modules.txt</code>.
-</p>
-
-<h4 id="go-flags">Flags</h4>
-
-<p><!-- golang.org/issue/32502, golang.org/issue/30345 -->
-  The <code>go</code> <code>get</code> command no longer accepts
-  the <code>-mod</code> flag. Previously, the flag's setting either
-  <a href="https://golang.org/issue/30345">was ignored</a> or
-  <a href="https://golang.org/issue/32502">caused the build to fail</a>.
-</p>
-
-<p><!-- golang.org/issue/33326 -->
-  <code>-mod=readonly</code> is now set by default when the <code>go.mod</code>
-  file is read-only and no top-level <code>vendor</code> directory is present.
-</p>
-
-<p><!-- golang.org/issue/31481 -->
-  <code>-modcacherw</code> is a new flag that instructs the <code>go</code>
-  command to leave newly-created directories in the module cache at their
-  default permissions rather than making them read-only.
-  The use of this flag makes it more likely that tests or other tools will
-  accidentally add files not included in the module's verified checksum.
-  However, it allows the use of <code>rm</code> <code>-rf</code>
-  (instead of <code>go</code> <code>clean</code> <code>-modcache</code>)
-  to remove the module cache.
-</p>
-
-<p><!-- golang.org/issue/34506 -->
-  <code>-modfile=file</code> is a new flag that instructs the <code>go</code>
-  command to read (and possibly write) an alternate <code>go.mod</code> file
-  instead of the one in the module root directory. A file
-  named <code>go.mod</code> must still be present in order to determine the
-  module root directory, but it is not accessed. When <code>-modfile</code> is
-  specified, an alternate <code>go.sum</code> file is also used: its path is
-  derived from the <code>-modfile</code> flag by trimming the <code>.mod</code>
-  extension and appending <code>.sum</code>.
-</p>
-
-<h4 id="go-env-vars">Environment variables</h4>
-
-<p><!-- golang.org/issue/32966 -->
-  <code>GOINSECURE</code> is a new environment variable that instructs
-  the <code>go</code> command to not require an HTTPS connection, and to skip
-  certificate validation, when fetching certain modules directly from their
-  origins. Like the existing <code>GOPRIVATE</code> variable, the value
-  of <code>GOINSECURE</code> is a comma-separated list of glob patterns.
-</p>
-
-<h4 id="commands-outside-modules">Commands outside modules</h4>
-
-<p><!-- golang.org/issue/32027 -->
-  When module-aware mode is enabled explicitly (by setting
-  <code>GO111MODULE=on</code>), most module commands have more
-  limited functionality if no <code>go.mod</code> file is present. For
-  example, <code>go</code> <code>build</code>,
-  <code>go</code> <code>run</code>, and other build commands can only build
-  packages in the standard library and packages specified as <code>.go</code>
-  files on the command line.
-</p>
-
-<p>
-  Previously, the <code>go</code> command would resolve each package path
-  to the latest version of a module but would not record the module path
-  or version. This resulted in <a href="https://golang.org/issue/32027">slow,
-  non-reproducible builds</a>.
-</p>
-
-<p>
-  <code>go</code> <code>get</code> continues to work as before, as do
-  <code>go</code> <code>mod</code> <code>download</code> and
-  <code>go</code> <code>list</code> <code>-m</code> with explicit versions.
-</p>
-
-<h4 id="incompatible-versions"><code>+incompatible</code> versions</h4>
-<!-- golang.org/issue/34165 -->
-
-<p>
-  If the latest version of a module contains a <code>go.mod</code> file,
-  <code>go</code> <code>get</code> will no longer upgrade to an
-  <a href="/cmd/go/#hdr-Module_compatibility_and_semantic_versioning">incompatible</a>
-  major version of that module unless such a version is requested explicitly
-  or is already required.
-  <code>go</code> <code>list</code> also omits incompatible major versions
-  for such a module when fetching directly from version control, but may
-  include them if reported by a proxy.
-</p>
-
-
-<h4 id="go.mod"><code>go.mod</code> file maintenance</h4>
-<!-- golang.org/issue/34822 -->
-
-<p>
-  <code>go</code> commands other than
-  <code>go</code> <code>mod</code> <code>tidy</code> no longer
-  remove a <code>require</code> directive that specifies a version of an indirect dependency
-  that is already implied by other (transitive) dependencies of the main
-  module.
-</p>
-
-<p>
-  <code>go</code> commands other than
-  <code>go</code> <code>mod</code> <code>tidy</code> no longer
-  edit the <code>go.mod</code> file if the changes are only cosmetic.
-</p>
-
-<p>
-  When <code>-mod=readonly</code> is set, <code>go</code> commands will no
-  longer fail due to a missing <code>go</code> directive or an erroneous
-  <code>//&nbsp;indirect</code> comment.
-</p>
-
-<h4 id="module-downloading">Module downloading</h4>
-
-<p><!-- golang.org/issue/26092 -->
-  The <code>go</code> command now supports Subversion repositories in module mode.
-</p>
-
-<p><!-- golang.org/issue/30748 -->
-  The <code>go</code> command now includes snippets of plain-text error messages
-  from module proxies and other HTTP servers.
-  An error message will only be shown if it is valid UTF-8 and consists of only
-  graphic characters and spaces.
-</p>
-
-<h4 id="go-test">Testing</h4>
-
-<p><!-- golang.org/issue/24929 -->
-  <code>go test -v</code> now streams <code>t.Log</code> output as it happens,
-  rather than at the end of all tests.
-</p>
-
-<h2 id="runtime">Runtime</h2>
-
-<p><!-- CL 190098 -->
-  This release improves the performance of most uses
-  of <code>defer</code> to incur almost zero overhead compared to
-  calling the deferred function directly.
-  As a result, <code>defer</code> can now be used in
-  performance-critical code without overhead concerns.
-</p>
-
-<p><!-- CL 201760, CL 201762 and many others -->
-  Goroutines are now asynchronously preemptible.
-  As a result, loops without function calls no longer potentially
-  deadlock the scheduler or significantly delay garbage collection.
-  This is supported on all platforms except <code>windows/arm</code>,
-  <code>darwin/arm</code>, <code>js/wasm</code>, and
-  <code>plan9/*</code>.
-</p>
-
-<p>
-  A consequence of the implementation of preemption is that on Unix
-  systems, including Linux and macOS systems, programs built with Go
-  1.14 will receive more signals than programs built with earlier
-  releases.
-  This means that programs that use packages
-  like <a href="/pkg/syscall/"><code>syscall</code></a>
-  or <a href="https://godoc.org/golang.org/x/sys/unix"><code>golang.org/x/sys/unix</code></a>
-  will see more slow system calls fail with <code>EINTR</code> errors.
-  Those programs will have to handle those errors in some way, most
-  likely looping to try the system call again.  For more
-  information about this
-  see <a href="http://man7.org/linux/man-pages/man7/signal.7.html"><code>man
-  7 signal</code></a> for Linux systems or similar documentation for
-  other systems.
-</p>
-
-<p><!-- CL 201765, CL 195701 and many others -->
-  The page allocator is more efficient and incurs significantly less
-  lock contention at high values of <code>GOMAXPROCS</code>.
-  This is most noticeable as lower latency and higher throughput for
-  large allocations being done in parallel and at a high rate.
-</p>
-
-<p><!-- CL 171844 and many others -->
-  Internal timers, used by
-  <a href="/pkg/time/#After"><code>time.After</code></a>,
-  <a href="/pkg/time/#Tick"><code>time.Tick</code></a>,
-  <a href="/pkg/net/#Conn"><code>net.Conn.SetDeadline</code></a>,
-  and friends, are more efficient, with less lock contention and fewer
-  context switches.
-  This is a performance improvement that should not cause any user
-  visible changes.
-</p>
-
-<h2 id="compiler">Compiler</h2>
-
-<p><!-- CL 162237 -->
-  This release adds <code>-d=checkptr</code> as a compile-time option
-  for adding instrumentation to check that Go code is following
-  <code>unsafe.Pointer</code> safety rules dynamically.
-  This option is enabled by default (except on Windows) with
-  the <code>-race</code> or <code>-msan</code> flags, and can be
-  disabled with <code>-gcflags=all=-d=checkptr=0</code>.
-  Specifically, <code>-d=checkptr</code> checks the following:
-</p>
-
-<ol>
-  <li>
-    When converting <code>unsafe.Pointer</code> to <code>*T</code>,
-    the resulting pointer must be aligned appropriately
-    for <code>T</code>.
-  </li>
-  <li>
-    If the result of pointer arithmetic points into a Go heap object,
-    one of the <code>unsafe.Pointer</code>-typed operands must point
-    into the same object.
-  </li>
-</ol>
-
-<p>
-  Using <code>-d=checkptr</code> is not currently recommended on
-  Windows because it causes false alerts in the standard library.
-</p>
-
-<p><!-- CL 204338 -->
-  The compiler can now emit machine-readable logs of key optimizations
-  using the <code>-json</code> flag, including inlining, escape
-  analysis, bounds-check elimination, and nil-check elimination.
-</p>
-
-<p><!-- CL 196959 -->
-  Detailed escape analysis diagnostics (<code>-m=2</code>) now work again.
-  This had been dropped from the new escape analysis implementation in
-  the previous release.
-</p>
-
-<p><!-- CL 196217 -->
-  All Go symbols in macOS binaries now begin with an underscore,
-  following platform conventions.
-</p>
-
-<p><!-- CL 202117 -->
-  This release includes experimental support for compiler-inserted
-  coverage instrumentation for fuzzing.
-  See <a href="https://golang.org/issue/14565">issue 14565</a> for more
-  details.
-  This API may change in future releases.
-</p>
-
-<p><!-- CL 174704 --><!-- CL 196784 -->
-  Bounds check elimination now uses information from slice creation and can
-  eliminate checks for indexes with types smaller than <code>int</code>.

-
-<h3 id="hash/maphash">New byte sequence hashing package</h3>
-
-<p> <!-- golang.org/issue/28322, CL 186877 -->
-  Go 1.14 includes a new package,
-  <a href="/pkg/hash/maphash/"><code>hash/maphash</code></a>,
-  which provides hash functions on byte sequences.
-  These hash functions are intended to be used to implement hash tables or
-  other data structures that need to map arbitrary strings or byte
-  sequences to a uniform distribution on unsigned 64-bit integers.
-</p>
-<p>
-  The hash functions are collision-resistant but not cryptographically secure.
-</p>
-<p>
-  The hash value of a given byte sequence is consistent within a
-  single process, but will be different in different processes.
-</p>
-
-<h3 id="minor_library_changes">Minor changes to the library</h3>
-
-<p>
-  As always, there are various minor changes and updates to the library,

-    </p>
-
-    <p><!-- CL 191999 -->
-      TLS 1.3 can't be disabled via the <code>GODEBUG</code> environment

-      When multiple certificate chains are provided through the

-
-    <p><!-- CL 174329 -->
-      The <code>tls</code> package no longer supports the legacy Next Protocol

-<h2 id="introduction">Introduction to Go 1.6</h2>
-
-<p>
-The latest Go release, version 1.6, arrives six months after 1.5.
-Most of its changes are in the implementation of the language, runtime, and libraries.
-There are no changes to the language specification.
-As always, the release maintains the Go 1 <a href="/doc/go1compat.html">promise of compatibility</a>.
-We expect almost all Go programs to continue to compile and run as before.
-</p>
-
-<p>
-The release adds new ports to <a href="#ports">Linux on 64-bit MIPS and Android on 32-bit x86</a>;
-defined and enforced <a href="#cgo">rules for sharing Go pointers with C</a>;
-transparent, automatic <a href="#http2">support for HTTP/2</a>;
-and a new mechanism for <a href="#template">template reuse</a>.
-</p>
-
-<h2 id="language">Changes to the language</h2>
-
-<p>
-There are no language changes in this release.
-</p>
-
-<h2 id="ports">Ports</h2>
-
-<p>
-Go 1.6 adds experimental ports to
-Linux on 64-bit MIPS (<code>linux/mips64</code> and <code>linux/mips64le</code>).
-These ports support <code>cgo</code> but only with internal linking.
-</p>
-
-<p>
-Go 1.6 also adds an experimental port to Android on 32-bit x86 (<code>android/386</code>).
-</p>
-
-<p>
-On FreeBSD, Go 1.6 defaults to using <code>clang</code>, not <code>gcc</code>, as the external C compiler.
-</p>
-
-<p>
-On Linux on little-endian 64-bit PowerPC (<code>linux/ppc64le</code>),
-Go 1.6 now supports <code>cgo</code> with external linking and
-is roughly feature complete.
-</p>
-
-<p>
-On NaCl, Go 1.5 required SDK version pepper-41.
-Go 1.6 adds support for later SDK versions.
-</p>
-
-<p>
-On 32-bit x86 systems using the <code>-dynlink</code> or <code>-shared</code> compilation modes,
-the register CX is now overwritten by certain memory references and should
-be avoided in hand-written assembly.
-See the <a href="/doc/asm#x86">assembly documentation</a> for details.
-</p>
-
-<h2 id="tools">Tools</h2>
-
-<h3 id="cgo">Cgo</h3>
-
-<p>
-There is one major change to <a href="/cmd/cgo/"><code>cgo</code></a>, along with one minor change.
-</p>
-
-<p>
-The major change is the definition of rules for sharing Go pointers with C code,
-to ensure that such C code can coexist with Go's garbage collector.
-Briefly, Go and C may share memory allocated by Go
-when a pointer to that memory is passed to C as part of a <code>cgo</code> call,
-provided that the memory itself contains no pointers to Go-allocated memory,
-and provided that C does not retain the pointer after the call returns.
-These rules are checked by the runtime during program execution:
-if the runtime detects a violation, it prints a diagnosis and crashes the program.
-The checks can be disabled by setting the environment variable
-<code>GODEBUG=cgocheck=0</code>, but note that the vast majority of
-code identified by the checks is subtly incompatible with garbage collection
-in one way or another.
-Disabling the checks will typically only lead to more mysterious failure modes.
-Fixing the code in question should be strongly preferred
-over turning off the checks.
-See the <a href="/cmd/cgo/#hdr-Passing_pointers"><code>cgo</code> documentation</a> for more details.
-</p>
-
-<p>
-The minor change is
-the addition of explicit <code>C.complexfloat</code> and <code>C.complexdouble</code> types,
-separate from Go's <code>complex64</code> and <code>complex128</code>.
-Matching the other numeric types, C's complex types and Go's complex type are
-no longer interchangeable.
-</p>
-
-<h3 id="compiler">Compiler Toolchain</h3>
-
-<p>
-The compiler toolchain is mostly unchanged.
-Internally, the most significant change is that the parser is now hand-written
-instead of generated from <a href="/cmd/yacc/">yacc</a>.
-</p>
-
-<p>
-The compiler, linker, and <code>go</code> command have a new flag <code>-msan</code>,
-analogous to <code>-race</code> and only available on linux/amd64,
-that enables interoperation with the <a href="https://clang.llvm.org/docs/MemorySanitizer.html">Clang MemorySanitizer</a>.
-Such interoperation is useful mainly for testing a program containing suspect C or C++ code.
-</p>
-
-<p>
-The linker has a new option <code>-libgcc</code> to set the expected location
-of the C compiler support library when linking <a href="/cmd/cgo/"><code>cgo</code></a> code.
-The option is only consulted when using <code>-linkmode=internal</code>,
-and it may be set to <code>none</code> to disable the use of a support library.
-</p>
-
-<p>
-The implementation of <a href="/doc/go1.5#link">build modes started in Go 1.5</a> has been expanded to more systems.
-This release adds support for the <code>c-shared</code> mode on <code>android/386</code>, <code>android/amd64</code>,
-<code>android/arm64</code>, <code>linux/386</code>, and <code>linux/arm64</code>;
-for the <code>shared</code> mode on <code>linux/386</code>, <code>linux/arm</code>, <code>linux/amd64</code>, and <code>linux/ppc64le</code>;
-and for the new <code>pie</code> mode (generating position-independent executables) on
-<code>android/386</code>, <code>android/amd64</code>, <code>android/arm</code>, <code>android/arm64</code>, <code>linux/386</code>,
-<code>linux/amd64</code>, <code>linux/arm</code>, <code>linux/arm64</code>, and <code>linux/ppc64le</code>.
-See the <a href="https://golang.org/s/execmodes">design document</a> for details.
-</p>
-
-<p>
-As a reminder, the linker's <code>-X</code> flag changed in Go 1.5.
-In Go 1.4 and earlier, it took two arguments, as in
-</p>
-
-<pre>
-X importpath.name value
-</pre>
-
-<p>
-Go 1.5 added an alternative syntax using a single argument
-that is itself a <code>name=value</code> pair:
-</p>
-
-<pre>
-X importpath.name=value
-</pre>
-
-<p>
-In Go 1.5 the old syntax was still accepted, after printing a warning
-suggesting use of the new syntax instead.
-Go 1.6 continues to accept the old syntax and print the warning.
-Go 1.7 will remove support for the old syntax.
-</p>
-
-<h3 id="gccgo">Gccgo</h3>
-
-<p>
-The release schedules for the GCC and Go projects do not coincide.
-GCC release 5 contains the Go 1.4 version of gccgo.
-The next release, GCC 6, will have the Go 1.6.1 version of gccgo.
-</p>
-
-<h3 id="go_command">Go command</h3>
-
-<p>
-The <a href="/cmd/go"><code>go</code></a> command's basic operation
-is unchanged, but there are a number of changes worth noting.
-</p>
-
-<p>
-Go 1.5 introduced experimental support for vendoring,
-enabled by setting the <code>GO15VENDOREXPERIMENT</code> environment variable to <code>1</code>.
-Go 1.6 keeps the vendoring support, no longer considered experimental,
-and enables it by default.
-It can be disabled explicitly by setting
-the <code>GO15VENDOREXPERIMENT</code> environment variable to <code>0</code>.
-Go 1.7 will remove support for the environment variable.
-</p>
-
-<p>
-The most likely problem caused by enabling vendoring by default happens
-in source trees containing an existing directory named <code>vendor</code> that
-does not expect to be interpreted according to new vendoring semantics.
-In this case, the simplest fix is to rename the directory to anything other
-than <code>vendor</code> and update any affected import paths.
-</p>
-
-<p>
-For details about vendoring,
-see the documentation for the <a href="/cmd/go/#hdr-Vendor_Directories"><code>go</code> command</a>
-and the <a href="https://golang.org/s/go15vendor">design document</a>.
-</p>
-
-<p>
-There is a new build flag, <code>-msan</code>,
-that compiles Go with support for the LLVM memory sanitizer.
-This is intended mainly for use when linking against C or C++ code
-that is being checked with the memory sanitizer.
-</p>
-
-<h3 id="doc_command">Go doc command</h3>
-
-<p>
-Go 1.5 introduced the
-<a href="/cmd/go/#hdr-Show_documentation_for_package_or_symbol"><code>go doc</code></a> command,
-which allows references to packages using only the package name, as in
-<code>go</code> <code>doc</code> <code>http</code>.
-In the event of ambiguity, the Go 1.5 behavior was to use the package
-with the lexicographically earliest import path.
-In Go 1.6, ambiguity is resolved by preferring import paths with
-fewer elements, breaking ties using lexicographic comparison.
-An important effect of this change is that original copies of packages
-are now preferred over vendored copies.
-Successful searches also tend to run faster.
-</p>
-
-<h3 id="vet_command">Go vet command</h3>
-
-<p>
-The <a href="/cmd/vet"><code>go vet</code></a> command now diagnoses
-passing function or method values as arguments to <code>Printf</code>,
-such as when passing <code>f</code> where <code>f()</code> was intended.
-</p>
-
-<h2 id="performance">Performance</h2>
-
-<p>
-As always, the changes are so general and varied that precise statements
-about performance are difficult to make.
-Some programs may run faster, some slower.
-On average the programs in the Go 1 benchmark suite run a few percent faster in Go 1.6
-than they did in Go 1.5.
-The garbage collector's pauses are even lower than in Go 1.5,
-especially for programs using
-a large amount of memory.
-</p>
-
-<p>
-There have been significant optimizations bringing more than 10% improvements
-to implementations of the
-<a href="/pkg/compress/bzip2/"><code>compress/bzip2</code></a>,
-<a href="/pkg/compress/gzip/"><code>compress/gzip</code></a>,
-<a href="/pkg/crypto/aes/"><code>crypto/aes</code></a>,
-<a href="/pkg/crypto/elliptic/"><code>crypto/elliptic</code></a>,
-<a href="/pkg/crypto/ecdsa/"><code>crypto/ecdsa</code></a>, and
-<a href="/pkg/sort/"><code>sort</code></a> packages.
-</p>
-
-<h2 id="library">Core library</h2>
-
-<h3 id="http2">HTTP/2</h3>
-
-<p>
-Go 1.6 adds transparent support in the
-<a href="/pkg/net/http/"><code>net/http</code></a> package
-for the new <a href="https://http2.github.io/">HTTP/2 protocol</a>.
-Go clients and servers will automatically use HTTP/2 as appropriate when using HTTPS.
-There is no exported API specific to details of the HTTP/2 protocol handling,
-just as there is no exported API specific to HTTP/1.1.
-</p>
-
-<p>
-Programs that must disable HTTP/2 can do so by setting
-<a href="/pkg/net/http/#Transport"><code>Transport.TLSNextProto</code></a> (for clients)
-or
-<a href="/pkg/net/http/#Server"><code>Server.TLSNextProto</code></a> (for servers)
-to a non-nil, empty map.
-</p>
-
-<p>
-Programs that must adjust HTTP/2 protocol-specific details can import and use
-<a href="https://golang.org/x/net/http2"><code>golang.org/x/net/http2</code></a>,
-in particular its
-<a href="https://godoc.org/golang.org/x/net/http2/#ConfigureServer">ConfigureServer</a>
-and
-<a href="https://godoc.org/golang.org/x/net/http2/#ConfigureTransport">ConfigureTransport</a>
-functions.
-</p>
-
-<h3 id="runtime">Runtime</h3>
-
-<p>
-The runtime has added lightweight, best-effort detection of concurrent misuse of maps.
-As always, if one goroutine is writing to a map, no other goroutine should be
-reading or writing the map concurrently.
-If the runtime detects this condition, it prints a diagnosis and crashes the program.
-The best way to find out more about the problem is to run the program
-under the
-<a href="https://blog.golang.org/race-detector">race detector</a>,
-which will more reliably identify the race
-and give more detail.
-</p>
-
-<p>
-For program-ending panics, the runtime now by default
-prints only the stack of the running goroutine,
-not all existing goroutines.
-Usually only the current goroutine is relevant to a panic,
-so omitting the others significantly reduces irrelevant output
-in a crash message.
-To see the stacks from all goroutines in crash messages, set the environment variable
-<code>GOTRACEBACK</code> to <code>all</code>
-or call
-<a href="/pkg/runtime/debug/#SetTraceback"><code>debug.SetTraceback</code></a>
-before the crash, and rerun the program.
-See the <a href="/pkg/runtime/#hdr-Environment_Variables">runtime documentation</a> for details.
-</p>
-
-<p>
-<em>Updating</em>:
-Uncaught panics intended to dump the state of the entire program,
-such as when a timeout is detected or when explicitly handling a received signal,
-should now call <code>debug.SetTraceback("all")</code> before panicking.
-Searching for uses of
-<a href="/pkg/os/signal/#Notify"><code>signal.Notify</code></a> may help identify such code.
-</p>
-
-<p>
-On Windows, Go programs in Go 1.5 and earlier forced
-the global Windows timer resolution to 1ms at startup
-by calling <code>timeBeginPeriod(1)</code>.
-Go no longer needs this for good scheduler performance,
-and changing the global timer resolution caused problems on some systems,
-so the call has been removed.
-</p>
-
-<p>
-When using <code>-buildmode=c-archive</code> or
-<code>-buildmode=c-shared</code> to build an archive or a shared
-library, the handling of signals has changed.
-In Go 1.5 the archive or shared library would install a signal handler
-for most signals.
-In Go 1.6 it will only install a signal handler for the
-synchronous signals needed to handle run-time panics in Go code:
-SIGBUS, SIGFPE, SIGSEGV.
-See the <a href="/pkg/os/signal">os/signal</a> package for more
-details.
-</p>
-
-<h3 id="reflect">Reflect</h3>
-
-<p>
-The
-<a href="/pkg/reflect/"><code>reflect</code></a> package has
-<a href="https://golang.org/issue/12367">resolved a long-standing incompatibility</a>
-between the gc and gccgo toolchains
-regarding embedded unexported struct types containing exported fields.
-Code that walks data structures using reflection, especially to implement
-serialization in the spirit
-of the
-<a href="/pkg/encoding/json/"><code>encoding/json</code></a> and
-<a href="/pkg/encoding/xml/"><code>encoding/xml</code></a> packages,
-may need to be updated.
-</p>
-
-<p>
-The problem arises when using reflection to walk through
-an embedded unexported struct-typed field
-into an exported field of that struct.
-In this case, <code>reflect</code> had incorrectly reported
-the embedded field as exported, by returning an empty <code>Field.PkgPath</code>.
-Now it correctly reports the field as unexported
-but ignores that fact when evaluating access to exported fields
-contained within the struct.
-</p>
-
-<p>
-<em>Updating</em>:
-Typically, code that previously walked over structs and used
-</p>
-
-<pre>
-f.PkgPath != ""
-</pre>
-
-<p>
-to exclude inaccessible fields
-should now use
-</p>
-
-<pre>
-f.PkgPath != "" &amp;&amp; !f.Anonymous
-</pre>
-
-<p>
-For example, see the changes to the implementations of
-<a href="https://go-review.googlesource.com/#/c/14011/2/src/encoding/json/encode.go"><code>encoding/json</code></a> and
-<a href="https://go-review.googlesource.com/#/c/14012/2/src/encoding/xml/typeinfo.go"><code>encoding/xml</code></a>.
-</p>
-
-<h3 id="sort">Sorting</h3>
-
-<p>
-In the
-<a href="/pkg/sort/"><code>sort</code></a>
-package,
-the implementation of
-<a href="/pkg/sort/#Sort"><code>Sort</code></a>
-has been rewritten to make about 10% fewer calls to the
-<a href="/pkg/sort/#Interface"><code>Interface</code></a>'s
-<code>Less</code> and <code>Swap</code>
-methods, with a corresponding overall time savings.
-The new algorithm does choose a different ordering than before
-for values that compare equal (those pairs for which <code>Less(i,</code> <code>j)</code> and <code>Less(j,</code> <code>i)</code> are false).
-</p>
-
-<p>
-<em>Updating</em>:
-The definition of <code>Sort</code> makes no guarantee about the final order of equal values,
-but the new behavior may still break programs that expect a specific order.
-Such programs should either refine their <code>Less</code> implementations
-to report the desired order
-or should switch to
-<a href="/pkg/sort/#Stable"><code>Stable</code></a>,
-which preserves the original input order
-of equal values.
-</p>
-
-<h3 id="template">Templates</h3>
-
-<p>
-In the
-<a href="/pkg/text/template/">text/template</a> package,
-there are two significant new features to make writing templates easier.
-</p>
-
-<p>
-First, it is now possible to <a href="/pkg/text/template/#hdr-Text_and_spaces">trim spaces around template actions</a>,
-which can make template definitions more readable.
-A minus sign at the beginning of an action says to trim space before the action,
-and a minus sign at the end of an action says to trim space after the action.
-For example, the template
-</p>
-
-<pre>
-{{"{{"}}23 -}}
-   &lt;
-{{"{{"}}- 45}}
-</pre>
-
-<p>
-formats as <code>23&lt;45</code>.
-</p>
-
-<p>
-Second, the new <a href="/pkg/text/template/#hdr-Actions"><code>{{"{{"}}block}}</code> action</a>,
-combined with allowing redefinition of named templates,
-provides a simple way to define pieces of a template that
-can be replaced in different instantiations.
-There is <a href="/pkg/text/template/#example_Template_block">an example</a>
-in the <code>text/template</code> package that demonstrates this new feature.
-</p>
-
-<h3 id="minor_library_changes">Minor changes to the library</h3>
-
-<ul>
-
-<li>
-The <a href="/pkg/archive/tar/"><code>archive/tar</code></a> package's
-implementation corrects many bugs in rare corner cases of the file format.
-One visible change is that the
-<a href="/pkg/archive/tar/#Reader"><code>Reader</code></a> type's
-<a href="/pkg/archive/tar/#Reader.Read"><code>Read</code></a> method
-now presents the content of special file types as being empty,
-returning <code>io.EOF</code> immediately.
-</li>
-
-<li>
-In the <a href="/pkg/archive/zip/"><code>archive/zip</code></a> package, the
-<a href="/pkg/archive/zip/#Reader"><code>Reader</code></a> type now has a
-<a href="/pkg/archive/zip/#Reader.RegisterDecompressor"><code>RegisterDecompressor</code></a> method,
-and the
-<a href="/pkg/archive/zip/#Writer"><code>Writer</code></a> type now has a
-<a href="/pkg/archive/zip/#Writer.RegisterCompressor"><code>RegisterCompressor</code></a> method,
-enabling control over compression options for individual zip files.
-These take precedence over the pre-existing global
-<a href="/pkg/archive/zip/#RegisterDecompressor"><code>RegisterDecompressor</code></a> and
-<a href="/pkg/archive/zip/#RegisterCompressor"><code>RegisterCompressor</code></a> functions.
-</li>
-
-<li>
-The <a href="/pkg/bufio/"><code>bufio</code></a> package's
-<a href="/pkg/bufio/#Scanner"><code>Scanner</code></a> type now has a
-<a href="/pkg/bufio/#Scanner.Buffer"><code>Buffer</code></a> method,
-to specify an initial buffer and maximum buffer size to use during scanning.
-This makes it possible, when needed, to scan tokens larger than
-<code>MaxScanTokenSize</code>.
-Also for the <code>Scanner</code>, the package now defines the
-<a href="/pkg/bufio/#ErrFinalToken"><code>ErrFinalToken</code></a> error value, for use by
-<a href="/pkg/bufio/#SplitFunc">split functions</a> to abort processing or to return a final empty token.
-</li>
-
-<li>
-The <a href="/pkg/compress/flate/"><code>compress/flate</code></a> package
-has deprecated its

-<a href="/pkg/compress/flate/#WriteError"><code>WriteError</code></a> error implementations.
-In Go 1.5 they were only rarely returned when an error was encountered;
-now they are never returned, although they remain defined for compatibility.

-
-<li>
-The <a href="/pkg/compress/flate/"><code>compress/flate</code></a>,
-<a href="/pkg/compress/gzip/"><code>compress/gzip</code></a>, and
-<a href="/pkg/compress/zlib/"><code>compress/zlib</code></a> packages
-now report
-<a href="/pkg/io/#ErrUnexpectedEOF"><code>io.ErrUnexpectedEOF</code></a> for truncated input streams, instead of
-<a href="/pkg/io/#EOF"><code>io.EOF</code></a>.
-</li>
-
-<li>
-The <a href="/pkg/crypto/cipher/"><code>crypto/cipher</code></a> package now
-overwrites the destination buffer in the event of a GCM decryption failure.
-This is to allow the AESNI code to avoid using a temporary buffer.
-</li>
-
-<li>
-The <a href="/pkg/crypto/tls/"><code>crypto/tls</code></a> package
-has a variety of minor changes.
-It now allows
-<a href="/pkg/crypto/tls/#Listen"><code>Listen</code></a>
-to succeed when the
-<a href="/pkg/crypto/tls/#Config"><code>Config</code></a>
-has a nil <code>Certificates</code>, as long as the <code>GetCertificate</code> callback is set,
-it adds support for RSA with AES-GCM cipher suites,
-and
-it adds a
-<a href="/pkg/crypto/tls/#RecordHeaderError"><code>RecordHeaderError</code></a>
-to allow clients (in particular, the <a href="/pkg/net/http/"><code>net/http</code></a> package)
-to report a better error when attempting a TLS connection to a non-TLS server.
-</li>
-
-<li>
-The <a href="/pkg/crypto/x509/"><code>crypto/x509</code></a> package
-now permits certificates to contain negative serial numbers
-(technically an error, but unfortunately common in practice),
-and it defines a new
-<a href="/pkg/crypto/x509/#InsecureAlgorithmError"><code>InsecureAlgorithmError</code></a>
-to give a better error message when rejecting a certificate
-signed with an insecure algorithm like MD5.
-</li>
-
-<li>
-The <a href="/pkg/debug/dwarf"><code>debug/dwarf</code></a> and
-<a href="/pkg/debug/elf/"><code>debug/elf</code></a> packages
-together add support for compressed DWARF sections.
-User code needs no updating: the sections are decompressed automatically when read.
-</li>
-
-<li>
-The <a href="/pkg/debug/elf/"><code>debug/elf</code></a> package
-adds support for general compressed ELF sections.
-User code needs no updating: the sections are decompressed automatically when read.
-However, compressed
-<a href="/pkg/debug/elf/#Section"><code>Sections</code></a> do not support random access:
-they have a nil <code>ReaderAt</code> field.
-</li>
-
-<li>
-The <a href="/pkg/encoding/asn1/"><code>encoding/asn1</code></a> package
-now exports
-<a href="/pkg/encoding/asn1/#pkg-constants">tag and class constants</a>
-useful for advanced parsing of ASN.1 structures.
-</li>
-
-<li>
-Also in the <a href="/pkg/encoding/asn1/"><code>encoding/asn1</code></a> package,
-<a href="/pkg/encoding/asn1/#Unmarshal"><code>Unmarshal</code></a> now rejects various non-standard integer and length encodings.
-</li>
-
-<li>
-The <a href="/pkg/encoding/base64"><code>encoding/base64</code></a> package's
-<a href="/pkg/encoding/base64/#Decoder"><code>Decoder</code></a> has been fixed
-to process the final bytes of its input. Previously it processed as many four-byte tokens as
-possible but ignored the remainder, up to three bytes.
-The <code>Decoder</code> therefore now handles inputs in unpadded encodings (like
-<a href="/pkg/encoding/base64/#RawURLEncoding">RawURLEncoding</a>) correctly,
-but it also rejects inputs in padded encodings that are truncated or end with invalid bytes,
-such as trailing spaces.
-</li>
-
-<li>
-The <a href="/pkg/encoding/json/"><code>encoding/json</code></a> package
-now checks the syntax of a
-<a href="/pkg/encoding/json/#Number"><code>Number</code></a>
-before marshaling it, requiring that it conforms to the JSON specification for numeric values.
-As in previous releases, the zero <code>Number</code> (an empty string) is marshaled as a literal 0 (zero).
-</li>
-
-<li>
-The <a href="/pkg/encoding/xml/"><code>encoding/xml</code></a> package's
-<a href="/pkg/encoding/xml/#Marshal"><code>Marshal</code></a>
-function now supports a <code>cdata</code> attribute, such as <code>chardata</code>
-but encoding its argument in one or more <code>&lt;![CDATA[ ... ]]&gt;</code> tags.
-</li>
-
-<li>
-Also in the <a href="/pkg/encoding/xml/"><code>encoding/xml</code></a> package,
-<a href="/pkg/encoding/xml/#Decoder"><code>Decoder</code></a>'s
-<a href="/pkg/encoding/xml/#Decoder.Token"><code>Token</code></a> method
-now reports an error when encountering EOF before seeing all open tags closed,
-consistent with its general requirement that tags in the input be properly matched.
-To avoid that requirement, use
-<a href="/pkg/encoding/xml/#Decoder.RawToken"><code>RawToken</code></a>.
-</li>
-
-<li>
-The <a href="/pkg/fmt/"><code>fmt</code></a> package now allows
-any integer type as an argument to
-<a href="/pkg/fmt/#Printf"><code>Printf</code></a>'s <code>*</code> width and precision specification.
-In previous releases, the argument to <code>*</code> was required to have type <code>int</code>.
-</li>
-
-<li>
-Also in the <a href="/pkg/fmt/"><code>fmt</code></a> package,
-<a href="/pkg/fmt/#Scanf"><code>Scanf</code></a> can now scan hexadecimal strings using %X, as an alias for %x.
-Both formats accept any mix of upper- and lower-case hexadecimal.
-</li>
-
-<li>
-The <a href="/pkg/image/"><code>image</code></a>
-and
-<a href="/pkg/image/color/"><code>image/color</code></a> packages
-add
-<a href="/pkg/image/#NYCbCrA"><code>NYCbCrA</code></a>
-and
-<a href="/pkg/image/color/#NYCbCrA"><code>NYCbCrA</code></a>
-types, to support Y'CbCr images with non-premultiplied alpha.
-</li>
-
-<li>
-The <a href="/pkg/io/"><code>io</code></a> package's
-<a href="/pkg/io/#MultiWriter"><code>MultiWriter</code></a>
-implementation now implements a <code>WriteString</code> method,
-for use by
-<a href="/pkg/io/#WriteString"><code>WriteString</code></a>.
-</li>
-
-<li>
-In the <a href="/pkg/math/big/"><code>math/big</code></a> package,
-<a href="/pkg/math/big/#Int"><code>Int</code></a> adds
-<a href="/pkg/math/big/#Int.Append"><code>Append</code></a>
-and
-<a href="/pkg/math/big/#Int.Text"><code>Text</code></a>
-methods to give more control over printing.
-</li>
-
-<li>
-Also in the <a href="/pkg/math/big/"><code>math/big</code></a> package,
-<a href="/pkg/math/big/#Float"><code>Float</code></a> now implements
-<a href="/pkg/encoding/#TextMarshaler"><code>encoding.TextMarshaler</code></a> and
-<a href="/pkg/encoding/#TextUnmarshaler"><code>encoding.TextUnmarshaler</code></a>,
-allowing it to be serialized in a natural form by the
-<a href="/pkg/encoding/json/"><code>encoding/json</code></a> and
-<a href="/pkg/encoding/xml/"><code>encoding/xml</code></a> packages.
-</li>
-
-<li>
-Also in the <a href="/pkg/math/big/"><code>math/big</code></a> package,
-<a href="/pkg/math/big/#Float"><code>Float</code></a>'s
-<a href="/pkg/math/big/#Float.Append"><code>Append</code></a> method now supports the special precision argument -1.
-As in
-<a href="/pkg/strconv/#ParseFloat"><code>strconv.ParseFloat</code></a>,
-precision -1 means to use the smallest number of digits necessary such that
-<a href="/pkg/math/big/#Float.Parse"><code>Parse</code></a>
-reading the result into a <code>Float</code> of the same precision
-will yield the original value.
-</li>
-
-<li>
-The <a href="/pkg/math/rand/"><code>math/rand</code></a> package
-adds a
-<a href="/pkg/math/rand/#Read"><code>Read</code></a>
-function, and likewise
-<a href="/pkg/math/rand/#Rand"><code>Rand</code></a> adds a
-<a href="/pkg/math/rand/#Rand.Read"><code>Read</code></a> method.
-These make it easier to generate pseudorandom test data.
-Note that, like the rest of the package,
-these should not be used in cryptographic settings;
-for such purposes, use the <a href="/pkg/crypto/rand/"><code>crypto/rand</code></a> package instead.
-</li>
-
-<li>
-The <a href="/pkg/net/"><code>net</code></a> package's
-<a href="/pkg/net/#ParseMAC"><code>ParseMAC</code></a> function now accepts 20-byte IP-over-InfiniBand (IPoIB) link-layer addresses.
-</li>
-
-
-<li>
-Also in the <a href="/pkg/net/"><code>net</code></a> package,
-there have been a few changes to DNS lookups.
-First, the
-<a href="/pkg/net/#DNSError"><code>DNSError</code></a> error implementation now implements
-<a href="/pkg/net/#Error"><code>Error</code></a>,
-and in particular its new
-<a href="/pkg/net/#DNSError.IsTemporary"><code>IsTemporary</code></a>
-method returns true for DNS server errors.
-Second, DNS lookup functions such as
-<a href="/pkg/net/#LookupAddr"><code>LookupAddr</code></a>
-now return rooted domain names (with a trailing dot)
-on Plan 9 and Windows, to match the behavior of Go on Unix systems.
-</li>
-
-<li>
-The <a href="/pkg/net/http/"><code>net/http</code></a> package has
-a number of minor additions beyond the HTTP/2 support already discussed.
-First, the
-<a href="/pkg/net/http/#FileServer"><code>FileServer</code></a> now sorts its generated directory listings by file name.
-Second, the
-<a href="/pkg/net/http/#ServeFile"><code>ServeFile</code></a> function now refuses to serve a result
-if the request's URL path contains &ldquo;..&rdquo; (dot-dot) as a path element.
-Programs should typically use <code>FileServer</code> and 
-<a href="/pkg/net/http/#Dir"><code>Dir</code></a>
-instead of calling <code>ServeFile</code> directly.
-Programs that need to serve file content in response to requests for URLs containing dot-dot can 
-still call <a href="/pkg/net/http/#ServeContent"><code>ServeContent</code></a>.
-Third, the
-<a href="/pkg/net/http/#Client"><code>Client</code></a> now allows user code to set the
-<code>Expect:</code> <code>100-continue</code> header (see
-<a href="/pkg/net/http/#Transport"><code>Transport.ExpectContinueTimeout</code></a>).
-Fourth, there are
-<a href="/pkg/net/http/#pkg-constants">five new error codes</a>:
-<code>StatusPreconditionRequired</code> (428),
-<code>StatusTooManyRequests</code> (429),
-<code>StatusRequestHeaderFieldsTooLarge</code> (431), and
-<code>StatusNetworkAuthenticationRequired</code> (511) from RFC 6585,
-as well as the recently-approved
-<code>StatusUnavailableForLegalReasons</code> (451).
-Fifth, the implementation and documentation of
-<a href="/pkg/net/http/#CloseNotifier"><code>CloseNotifier</code></a>
-has been substantially changed.
-The <a href="/pkg/net/http/#Hijacker"><code>Hijacker</code></a>
-interface now works correctly on connections that have previously
-been used with <code>CloseNotifier</code>.
-The documentation now describes when <code>CloseNotifier</code>
-is expected to work.
-</li>
-
-<li>
-Also in the <a href="/pkg/net/http/"><code>net/http</code></a> package,
-there are a few changes related to the handling of a
-<a href="/pkg/net/http/#Request"><code>Request</code></a> data structure with its <code>Method</code> field set to the empty string.
-An empty <code>Method</code> field has always been documented as an alias for <code>"GET"</code>
-and it remains so.
-However, Go 1.6 fixes a few routines that did not treat an empty
-<code>Method</code> the same as an explicit <code>"GET"</code>.
-Most notably, in previous releases
-<a href="/pkg/net/http/#Client"><code>Client</code></a> followed redirects only with
-<code>Method</code> set explicitly to <code>"GET"</code>;
-in Go 1.6 <code>Client</code> also follows redirects for the empty <code>Method</code>.
-Finally,
-<a href="/pkg/net/http/#NewRequest"><code>NewRequest</code></a> accepts a <code>method</code> argument that has not been
-documented as allowed to be empty.
-In past releases, passing an empty <code>method</code> argument resulted
-in a <code>Request</code> with an empty <code>Method</code> field.
-In Go 1.6, the resulting <code>Request</code> always has an initialized
-<code>Method</code> field: if its argument is an empty string, <code>NewRequest</code>
-sets the <code>Method</code> field in the returned <code>Request</code> to <code>"GET"</code>.
-</li>
-
-<li>
-The <a href="/pkg/net/http/httptest/"><code>net/http/httptest</code></a> package's
-<a href="/pkg/net/http/httptest/#ResponseRecorder"><code>ResponseRecorder</code></a> now initializes a default Content-Type header
-using the same content-sniffing algorithm as in
-<a href="/pkg/net/http/#Server"><code>http.Server</code></a>.
-</li>
-
-<li>
-The <a href="/pkg/net/url/"><code>net/url</code></a> package's
-<a href="/pkg/net/url/#Parse"><code>Parse</code></a> is now stricter and more spec-compliant regarding the parsing
-of host names.
-For example, spaces in the host name are no longer accepted.
-</li>
-
-<li>
-Also in the <a href="/pkg/net/url/"><code>net/url</code></a> package,
-the <a href="/pkg/net/url/#Error"><code>Error</code></a> type now implements
-<a href="/pkg/net/#Error"><code>net.Error</code></a>.
-</li>
-
-<li>
-The <a href="/pkg/os/"><code>os</code></a> package's
-<a href="/pkg/os/#IsExist"><code>IsExist</code></a>,
-<a href="/pkg/os/#IsNotExist"><code>IsNotExist</code></a>,
-and
-<a href="/pkg/os/#IsPermission"><code>IsPermission</code></a>
-now return correct results when inquiring about an
-<a href="/pkg/os/#SyscallError"><code>SyscallError</code></a>.
-</li>
-
-<li>
-On Unix-like systems, when a write
-to <a href="/pkg/os/#pkg-variables"><code>os.Stdout</code>
-or <code>os.Stderr</code></a> (more precisely, an <code>os.File</code>
-opened for file descriptor 1 or 2) fails due to a broken pipe error,
-the program will raise a <code>SIGPIPE</code> signal.
-By default this will cause the program to exit; this may be changed by
-calling the
-<a href="/pkg/os/signal"><code>os/signal</code></a>
-<a href="/pkg/os/signal/#Notify"><code>Notify</code></a> function
-for <code>syscall.SIGPIPE</code>.
-A write to a broken pipe on a file descriptor other 1 or 2 will simply
-return <code>syscall.EPIPE</code> (possibly wrapped in
-<a href="/pkg/os#PathError"><code>os.PathError</code></a>
-and/or <a href="/pkg/os#SyscallError"><code>os.SyscallError</code></a>)
-to the caller.
-The old behavior of raising an uncatchable <code>SIGPIPE</code> signal
-after 10 consecutive writes to a broken pipe no longer occurs.
-</li>
-
-<li>
-In the <a href="/pkg/os/exec/"><code>os/exec</code></a> package,
-<a href="/pkg/os/exec/#Cmd"><code>Cmd</code></a>'s
-<a href="/pkg/os/exec/#Cmd.Output"><code>Output</code></a> method continues to return an
-<a href="/pkg/os/exec/#ExitError"><code>ExitError</code></a> when a command exits with an unsuccessful status.
-If standard error would otherwise have been discarded,
-the returned <code>ExitError</code> now holds a prefix and suffix
-(currently 32 kB) of the failed command's standard error output,
-for debugging or for inclusion in error messages.
-The <code>ExitError</code>'s
-<a href="/pkg/os/exec/#ExitError.String"><code>String</code></a>
-method does not show the captured standard error;
-programs must retrieve it from the data structure
-separately.
-</li>
-
-<li>
-On Windows, the <a href="/pkg/path/filepath/"><code>path/filepath</code></a> package's
-<a href="/pkg/path/filepath/#Join"><code>Join</code></a> function now correctly handles the case when the base is a relative drive path.
-For example, <code>Join(`c:`,</code> <code>`a`)</code> now
-returns <code>`c:a`</code> instead of <code>`c:\a`</code> as in past releases.
-This may affect code that expects the incorrect result.
-</li>
-
-<li>
-In the <a href="/pkg/regexp/"><code>regexp</code></a> package,
-the
-<a href="/pkg/regexp/#Regexp"><code>Regexp</code></a> type has always been safe for use by
-concurrent goroutines.
-It uses a <a href="/pkg/sync/#Mutex"><code>sync.Mutex</code></a> to protect
-a cache of scratch spaces used during regular expression searches.
-Some high-concurrency servers using the same <code>Regexp</code> from many goroutines
-have seen degraded performance due to contention on that mutex.
-To help such servers, <code>Regexp</code> now has a
-<a href="/pkg/regexp/#Regexp.Copy"><code>Copy</code></a> method,
-which makes a copy of a <code>Regexp</code> that shares most of the structure
-of the original but has its own scratch space cache.
-Two goroutines can use different copies of a <code>Regexp</code>
-without mutex contention.
-A copy does have additional space overhead, so <code>Copy</code>
-should only be used when contention has been observed.
-</li>
-
-<li>
-The <a href="/pkg/strconv/"><code>strconv</code></a> package adds
-<a href="/pkg/strconv/#IsGraphic"><code>IsGraphic</code></a>,
-similar to <a href="/pkg/strconv/#IsPrint"><code>IsPrint</code></a>.
-It also adds
-<a href="/pkg/strconv/#QuoteToGraphic"><code>QuoteToGraphic</code></a>,
-<a href="/pkg/strconv/#QuoteRuneToGraphic"><code>QuoteRuneToGraphic</code></a>,
-<a href="/pkg/strconv/#AppendQuoteToGraphic"><code>AppendQuoteToGraphic</code></a>,
-and
-<a href="/pkg/strconv/#AppendQuoteRuneToGraphic"><code>AppendQuoteRuneToGraphic</code></a>,
-analogous to
-<a href="/pkg/strconv/#QuoteToASCII"><code>QuoteToASCII</code></a>,
-<a href="/pkg/strconv/#QuoteRuneToASCII"><code>QuoteRuneToASCII</code></a>,
-and so on.
-The <code>ASCII</code> family escapes all space characters except ASCII space (U+0020).
-In contrast, the <code>Graphic</code> family does not escape any Unicode space characters (category Zs).
-</li>
-
-<li>
-In the <a href="/pkg/testing/"><code>testing</code></a> package,
-when a test calls
-<a href="/pkg/testing/#T.Parallel">t.Parallel</a>,
-that test is paused until all non-parallel tests complete, and then
-that test continues execution with all other parallel tests.
-Go 1.6 changes the time reported for such a test:
-previously the time counted only the parallel execution,
-but now it also counts the time from the start of testing
-until the call to <code>t.Parallel</code>.
-</li>
-
-<li>
-The <a href="/pkg/text/template/"><code>text/template</code></a> package
-contains two minor changes, in addition to the <a href="#template">major changes</a>
-described above.
-First, it adds a new
-<a href="/pkg/text/template/#ExecError"><code>ExecError</code></a> type
-returned for any error during
-<a href="/pkg/text/template/#Template.Execute"><code>Execute</code></a>
-that does not originate in a <code>Write</code> to the underlying writer.
-Callers can distinguish template usage errors from I/O errors by checking for
-<code>ExecError</code>.
-Second, the
-<a href="/pkg/text/template/#Template.Funcs"><code>Funcs</code></a> method
-now checks that the names used as keys in the
-<a href="/pkg/text/template/#FuncMap"><code>FuncMap</code></a>
-are identifiers that can appear in a template function invocation.
-If not, <code>Funcs</code> panics.
-</li>
-
-<li>
-The <a href="/pkg/time/"><code>time</code></a> package's
-<a href="/pkg/time/#Parse"><code>Parse</code></a> function has always rejected any day of month larger than 31,
-such as January 32.
-In Go 1.6, <code>Parse</code> now also rejects February 29 in non-leap years,
-February 30, February 31, April 31, June 31, September 31, and November 31.
-</li>
-

 <p>
-The Go toolchain is written in Go. To build it, you need a Go compiler installed.
-The scripts that do the initial build of the tools look for a "go" command
-in <code>$PATH</code>, so as long as you have Go installed in your
-system and configured in your <code>$PATH</code>, you are ready to build Go
-from source. 
-Or if you prefer you can set <code>$GOROOT_BOOTSTRAP</code> to the
-root of a Go installation to use to build the new Go toolchain;
-<code>$GOROOT_BOOTSTRAP/bin/go</code> should be the go command to use.</p>
-
-<h3 id="bootstrapFromBinaryRelease">Bootstrap toolchain from binary release</h3>
-
-<p>
-To use a binary release as a bootstrap toolchain, see
-<a href="/dl/">the downloads page</a> or use any other
-packaged Go distribution.
+The Go tool chain is written in C. To build it, you need a C compiler installed. 
+Please refer to the <a href="//golang.org/wiki/InstallFromSource#Install_C_tools">InstallFromSource</a>
+page on the Go community Wiki for operating system specific instructions.
 </p>

-<h3 id="bootstrapFromSource">Bootstrap toolchain from source</h3>
+<h2 id="mercurial">Install Mercurial, if needed</h2>

 <p>
-To build a bootstrap toolchain from source, use
-either the git branch <code>release-branch.go1.4</code> or
-<a href="https://dl.google.com/go/go1.4-bootstrap-20171003.tar.gz">go1.4-bootstrap-20171003.tar.gz</a>,
-which contains the Go 1.4 source code plus accumulated fixes
-to keep the tools running on newer operating systems.
-(Go 1.4 was the last distribution in which the toolchain was written in C.)
-After unpacking the Go 1.4 source, <code>cd</code> to
-the <code>src</code> subdirectory, set <code>CGO_ENABLED=0</code> in
-the environment, and run <code>make.bash</code> (or,
-on Windows, <code>make.bat</code>).
+To perform the next step you must have Mercurial installed. (Check that you
+have an <code>hg</code> command.)
 </p>

 <p>
-Once the Go 1.4 source has been unpacked into your GOROOT_BOOTSTRAP directory,
-you must keep this git clone instance checked out to branch
-<code>release-branch.go1.4</code>.  Specifically, do not attempt to reuse
-this git clone in the later step named "Fetch the repository."  The go1.4
-bootstrap toolchain <b>must be able</b> to properly traverse the go1.4 sources
-that it assumes are present under this repository root.

-</p>
-
-<pre>
-$ GOOS=linux GOARCH=ppc64 ./bootstrap.bash

-
-<p>
-<code>bootstrap.bash</code> cross-compiles a toolchain for that <code>GOOS/GOARCH</code>
-combination, leaving the resulting tree in <code>../../go-${GOOS}-${GOARCH}-bootstrap</code>.
-That tree can be copied to a machine of the given target type
-and used as <code>GOROOT_BOOTSTRAP</code> to bootstrap a local build.
-</p>
-
-<h3 id="bootstrapFromGccgo">Bootstrap toolchain using gccgo</h3>
-
-<p>
-To use gccgo as the bootstrap toolchain, you need to arrange
-for <code>$GOROOT_BOOTSTRAP/bin/go</code> to be the go tool that comes
-as part of gccgo 5. For example on Ubuntu Vivid:
-</p>
-
-<pre>
-$ sudo apt-get install gccgo-5

Note the issue isn't long "//go:generate" lines, but any long line in any Go source file. To be fair, if you're going to have a stupid long line it's not a bad bet you'll want to run it through go generate, because it's some embeddable asset that has been machine generated. (One could ask why that generation process didn't add a newline or two, but we should cope anyway.) Rewrite the file scanner in "go generate" so it can handle arbitrarily long lines, and only stores in memory those lines that start "//go:generate". Also: Adjust the documentation to make clear that it does not parse the file. Fixes #9143. Fixes #9196.

Russ Cox	28208eb8e3	[release-branch.go1.4] runtime: fix hang in GC due to shrinkstack vs netpoll race ««« CL 179680043 / 752cd9199639 runtime: fix hang in GC due to shrinkstack vs netpoll race During garbage collection, after scanning a stack, we think about shrinking it to reclaim some memory. The shrinking code (called while the world is stopped) checked that the status was Gwaiting or Grunnable and then changed the state to Gcopystack, to essentially lock the stack so that no other GC thread is scanning it. The same locking happens for stack growth (and is more necessary there). oldstatus = runtime·readgstatus(gp); oldstatus &= ~Gscan; if(oldstatus == Gwaiting \|\| oldstatus == Grunnable) runtime·casgstatus(gp, oldstatus, Gcopystack); // oldstatus is Gwaiting or Grunnable else runtime·throw("copystack: bad status, not Gwaiting or Grunnable"); Unfortunately, "stop the world" doesn't stop everything. It stops all normal goroutine execution, but the network polling thread is still blocked in epoll and may wake up. If it does, and it chooses a goroutine to mark runnable, and that goroutine is the one whose stack is shrinking, then it can happen that between readgstatus and casgstatus, the status changes from Gwaiting to Grunnable. casgstatus assumes that if the status is not what is expected, it is a transient change (like from Gwaiting to Gscanwaiting and back, or like from Gwaiting to Gcopystack and back), and it loops until the status has been restored to the expected value. In this case, the status has changed semi-permanently from Gwaiting to Grunnable - it won't change again until the GC is done and the world can continue, but the GC is waiting for the status to change back. This wedges the program. To fix, call a special variant of casgstatus that accepts either Gwaiting or Grunnable as valid statuses. Without the fix bug with the extra check+throw in casgstatus, the program below dies in a few seconds (2-10) with GOMAXPROCS=8 on a 2012 Retina MacBook Pro. With the fix, it runs for minutes and minutes. package main import ( "io" "log" "net" "runtime" ) func main() { const N = 100 for i := 0; i < N; i++ { l, err := net.Listen("tcp", "127.0.0.1:0") if err != nil { log.Fatal(err) } ch := make(chan net.Conn, 1) go func() { var err error c1, err := net.Dial("tcp", l.Addr().String()) if err != nil { log.Fatal(err) } ch <- c1 }() c2, err := l.Accept() if err != nil { log.Fatal(err) } c1 := <-ch l.Close() go netguy(c1, c2) go netguy(c2, c1) c1.Write(make([]byte, 100)) } for { runtime.GC() } } func netguy(r, w net.Conn) { buf := make([]byte, 100) for { bigstack(1000) _, err := io.ReadFull(r, buf) if err != nil { log.Fatal(err) } w.Write(buf) } } var g int func bigstack(n int) { var buf [100]byte if n > 0 { bigstack(n - 1) } g = int(buf[0]) + int(buf[99]) } Fixes #9186.

The corresponding address checks for atomic operations were removed in https://golang.org/cl/111310044 Restore these checks. It's tricker than just not calling into race runtime, because it is the race runtime that makes the atomic operations themselves (if we do not call into race runtime we skip the atomic operation itself as well). So instead we call __tsan_go_ignore_sync_start/end around the atomic operation. This forces race runtime to skip all other processing except than doing the atomic operation itself. Fixes #9136.

I looked briefly at trying to write out the _go_.o in external linking mode in a way that forced the ordering, but no matter what there's no way to force Go's data and Go's bss to be next to each other. If there is any data or bss from non-Go objects, it's very likely to get stuck in between them. Instead, rewrite the two places we know about that make the assumption. I grepped for noptrdata to look for more and didn't find any. The added race test (os/exec in external linking mode) fails without the changes in the runtime. It crashes with an invalid pointer dereference. Fixes #9133.
