<h4 id="go-unix">New <code>unix</code> build constraint</h4>
|
|
|
|
<p><!-- CL 389934 -->
|
|
The build constraint <code>unix</code> is now recognized
|
|
in <code>//go:build</code> lines. The constraint is satisfied
|
|
if the target operating system, also known as <code>GOOS</code>, is
|
|
a Unix or Unix-like system. For the 1.19 release it is satisfied
|
|
if <code>GOOS</code> is one of
|
|
<code>aix</code>, <code>android</code>, <code>darwin</code>,
|
|
<code>dragonfly</code>, <code>freebsd</code>, <code>hurd</code>,
|
|
<code>illumos</code>, <code>ios</code>, <code>linux</code>,
|
|
<code>netbsd</code>, <code>openbsd</code>, or <code>solaris</code>.
|
|
In future releases the <code>unix</code> constraint may match
|
|
additional newly supported operating systems.

|
|
The pure Go resolver will now use EDNS(0) to include a suggested
|
|
maximum reply packet length, permitting reply packets to contain
|
|
up to 1232 bytes (the previous maximum was 512).
|
|
In the unlikely event that this causes problems with a local DNS
|
|
resolver, setting the environment variable
|
|
<code>GODEBUG=netdns=cgo</code> to use the cgo-based resolver
|
|
should work.
|
|
Please report any such problems on <a href="/issue/new">the
|
|
issue tracker</a>.
