<title>Release 2.3 (2019-09-04)</title>
|
|
|
|
<para>This is primarily a bug fix release. However, it makes some
|
|
incompatible changes:</para>
|
|
|
|
<itemizedlist>
|
|
|
|
<listitem>
|
|
<para>Nix now uses BSD file locks instead of POSIX file
|
|
locks. Because of this, you should not use Nix 2.3 and previous
|
|
releases at the same time on a Nix store.</para>
|
|
</listitem>
|
|
|
|
</itemizedlist>
|
|
|
|
<para>It also has the following changes:</para>
|
|
|
|
<itemizedlist>
|
|
|
|
<listitem>
|
|
<para><function>builtins.fetchGit</function>'s <varname>ref</varname>
|
|
argument now allows specifying an absolute remote ref.
|
|
Nix will automatically prefix <varname>ref</varname> with
|
|
<literal>refs/heads</literal> only if <varname>ref</varname> doesn't
|
|
already begin with <literal>refs/</literal>.
|
|
</para>
|
|
</listitem>
|
|
|
|
<listitem>
|
|
<para>The installer now enables sandboxing by default on Linux when the
|
|
system has the necessary kernel support.
|
|
</para>
|
|
</listitem>
|
|
|
|
<listitem>
|
|
<para>The <literal>max-jobs</literal> setting now defaults to 1.</para>
|
|
</listitem>
|
|
|
|
<listitem>
|
|
<para>New builtin functions:
|
|
<literal>builtins.isPath</literal>,
|
|
<literal>builtins.hashFile</literal>.
|
|
</para>
|
|
</listitem>
|
|
|
|
<listitem>
|
|
<para>The <command>nix</command> command has a new
|
|
<option>--print-build-logs</option> (<option>-L</option>) flag to
|
|
print build log output to stderr, rather than showing the last log
|
|
line in the progress bar. To distinguish between concurrent
|
|
builds, log lines are prefixed by the name of the package.
|
|
</para>
|
|
</listitem>
|
|
|
|
<listitem>
|
|
<para>Builds are now executed in a pseudo-terminal, and the
|
|
<envar>TERM</envar> environment variable is set to
|
|
<literal>xterm-256color</literal>. This allows many programs
|
|
(e.g. <command>gcc</command>, <command>clang</command>,
|
|
<command>cmake</command>) to print colorized log output.</para>
|
|
</listitem>
|
|
|
|
<listitem>
|
|
<para>Add <option>--no-net</option> convenience flag. This flag
|
|
disables substituters; sets the <literal>tarball-ttl</literal>
|
|
setting to infinity (ensuring that any previously downloaded files
|
|
are considered current); and disables retrying downloads and sets
|
|
the connection timeout to the minimum. This flag is enabled
|
|
automatically if there are no configured non-loopback network
|
|
interfaces.</para>

<listitem>

<para>Add a <literal>post-build-hook</literal> setting to run a
|
|
program after a build has succeeded.</para>

</listitem>

|
<listitem>
|

<para>Add a <literal>trace-function-calls</literal> setting to log
|
|
the duration of Nix function calls to stderr.</para>
