IsLocal reports whether a path lexically refers to a location contained within the directory in which it is evaluated. It identifies paths that are absolute, escape a directory with ".." elements, and (on Windows) paths that reference reserved device names. For #56219.

|
|
The Go distribution no longer ships with pre-compiled <code>.a</code>
|
|
files for most of the packages in <code>GOROOT</code>, now only including
|
|
.a files for the five packages in <code>GOROOT</code> that use <code>cgo</code>.
|
|
Instead, those packages will be built as needed and cached in the build
|
|
cache, as is already done for non-<code>main</code> packages outside
|
|
<code>GOROOT</code>. Further, <code>go</code> <code>install</code> will
|
|
also not install <code>.a</code> files for <code>GOROOT</code> packages
|
|
except for those that use <code>cgo</code>. These changes are intended to
|
|
reduce the size of the Go distribution, in some cases by up to two-thirds.

non-<code>main</code> packages to <code>GOPATH/pkg</code>,

and <code>go</code> <code>list</code> no longer reports a <code>Target</code>

field for such packages. (In module mode, compiled packages are stored in the
|
|
<a href="https://pkg.go.dev/cmd/go#hdr-Build_and_test_caching">build cache</a>
|
|
only, but <a href="https://go.dev/issue/37015">a bug</a> had caused
|
|
the <code>GOPATH</code> install targets to unexpectedly remain in effect.)

<h3 id="errors">Wrapping multiple errors</h3>
|
|
|
|
<p><!-- CL 432898 -->
|
|
Go 1.20 expands support for error wrapping to permit an error to
|
|
wrap multiple other errors.
|
|
</p>
|
|
<p>
|
|
An error <code>e</code</e> can wrap more than one error by providing
|
|
an <code>Unwrap</code> method that returns a <code>[]error</code>.
|
|
</p>
|
|
<p>
|
|
The <a href="/pkg/errors/#Is"><code>errors.Is</code></a> and
|
|
<a href="/pkg/errors/#As"><code>errors.As</code></a> functions
|
|
have been updated to inspect multiply wrapped errors.
|
|
</p>
|
|
<p>
|
|
The <a href="/pkg/fmt/#Errorf"><code>fmt.Errorf</code></a> function
|
|
now supports multiple occurrances of the <code>%w</code> format verb,
|
|
which will cause it to return an error that wraps all of those error operands.
|
|
</p>
|
|
<p>
|
|
The new function <a href="/pkg/errors/#Join"><code>errors.Join</code></a>
|
|
returns an error wrapping a list of errors.
|
|
</p>
|
|
|
|
<h3 id="http_responsecontroller">HTTP ResponseController</h3>
|
|
|
|
<p>
|
|
The new
|
|
<a href="/pkg/net/http/#ResponseController"><code>"net/http".ResponseController</code></a>
|
|
type provides access to extended per-request functionality not handled by the
|
|
<a href="/pkg/net/http/#ResponseWriter"><code>"net/http".ResponseWriter</code></a> interface.
|
|
</p>
|
|
|
|
<p>
|
|
Previously, we have added new per-request functionality by defining optional
|
|
interfaces which a <code>ResponseWriter</code> can implement, such as
|
|
<a href="/pkg/net/http/#Flusher"><code>Flusher<code></a>. These interfaces
|
|
are not discoverable and clumsy to use.
|
|
</p>
|
|
|
|
<p>
|
|
The <code>ResponseController</code> type provides a clearer, more discoverable way
|
|
to add per-handler controls. Two such controls also added in Go 1.20 are
|
|
<code>SetReadDeadline</code> and <code>SetWriteDeadline</code>, which allow setting
|
|
per-request read and write deadlines. For example:
|
|
</p>
|
|
|
|
<pre>
|
|
func RequestHandler(w ResponseWriter, r *Request) {
|
|
rc := http.NewResponseController(w)
|
|
rc.SetWriteDeadline(0) // disable Server.WriteTimeout when sending a large response
|
|
io.Copy(w, bigData)
|
|
}
|
|
</pre>
|
|
|
|
<h3 id="reverseproxy_rewrite">New ReverseProxy Rewrite hook</h3>
|
|
|
|
<p>
|
|
The <a href="/pkg/net/http/httputil/#ReverseProxy"><code>httputil.ReverseProxy</code></a>
|
|
forwarding proxy includes a new <code>Rewrite</code> hook function, superseding the
|
|
previous <code>Director</code> hook.
|
|
</p>
|
|
|
|
<p>
|
|
The <code>Rewrite</code> hook accepts a
|
|
<a href="/pkg/net/http/httputil/#ProxyRequest"><code>ProxyRequest</code></a> parameter,
|
|
which includes both the inbound request received by the proxy and the outbound
|
|
request that it will send.
|
|
Unlike <code>Director</code> hooks, which only operate on the outbound request,
|
|
this permits <code>Rewrite</code> hooks to avoid certain scenarios where
|
|
a malicious inbound request may cause headers added by the hook
|
|
to be removed before forwarding.
|
|
See <a href="https://go.dev/issue/50580">issue #50580</a>.
|
|
</p>
|
|
|
|
<p>
|
|
The <a href="/pkg/net/http/httputil/#ProxyRequest.SetURL"><code>ProxyRequest.SetURL</code></a>
|
|
method routes the outbound request to a provided destination
|
|
and supersedes the <code>NewSingleHostReverseProxy</code> function.
|
|
Unlike <code>NewSingleHostReverseProxy</code>, <code>SetURL</code>
|
|
also sets the <code>Host</code> header of the outbound request.
|
|
</p>
|
|
|
|
<p>
|
|
The
|
|
<a href="/pkg/net/http/httputil/#ProxyRequest.SetXForwarded"><code>ProxyRequest.SetXForwarded</code></a>
|
|
method sets the <code>X-Forwarded-For</code>, <code>X-Forwarded-Host</code>,
|
|
and <code>X-Forwarded-Proto</code> headers of the outbound request.
|
|
When using a <code>Rewrite</code>, these headers are not added by default.
|
|
</p>
|
|
|
|
<p>
|
|
An example of a <code>Rewrite</code> hook using these features is:
|
|
</p>
|
|
|
|
<pre>
|
|
proxyHandler := &httputil.ReverseProxy{
|
|
Rewrite: func(r *httputil.ProxyRequest) {
|
|
r.SetURL(outboundURL) // Forward request to outboundURL.
|
|
r.SetXForwarded() // Set X-Forwarded-* headers.
|
|
r.Out.Header.Set("X-Additional-Header", "header set by the proxy")
|
|
},
|
|
}
|
|
</pre>
|
|
|
|
<h3 id="minor_library_changes">Minor changes to the library</h3>
|
|
|
|
<p>
|
|
As always, there are various minor changes and updates to the library,
|
|
made with the Go 1 <a href="/doc/go1compat">promise of compatibility</a>
|
|
in mind.
|
|
There are also various performance improvements, not enumerated here.
