Here are the most significant:</para> - -<itemizedlist> - - <listitem> - <para>Nix can now optionally use the Boehm garbage collector. - This significantly reduces the Nix evaluator’s memory footprint, - especially when evaluating large NixOS system configurations. It - can be enabled using the <option>--enable-gc</option> configure - option.</para> - </listitem> - - <listitem> - <para>Nix now uses SQLite for its database. This is faster and - more flexible than the old <emphasis>ad hoc</emphasis> format. - SQLite is also used to cache the manifests in - <filename>/nix/var/nix/manifests</filename>, resulting in a - significant speedup.</para> - </listitem> - - <listitem> - <para>Nix now has an search path for expressions. The search path - is set using the environment variable <envar>NIX_PATH</envar> and - the <option>-I</option> command line option. In Nix expressions, - paths between angle brackets are used to specify files that must - be looked up in the search path. For instance, the expression - <literal><nixpkgs/default.nix></literal> looks for a file - <filename>nixpkgs/default.nix</filename> relative to every element - in the search path.</para> - </listitem> - - <listitem> - <para>The new command <command>nix-build --run-env</command> - builds all dependencies of a derivation, then starts a shell in an - environment containing all variables from the derivation. This is - useful for reproducing the environment of a derivation for - development.</para> - </listitem> - - <listitem> - <para>The new command <command>nix-store --verify-path</command> - verifies that the contents of a store path have not - changed.</para> - </listitem> - - <listitem> - <para>The new command <command>nix-store --print-env</command> - prints out the environment of a derivation in a format that can be - evaluated by a shell.</para> - </listitem> - - <listitem> - <para>Attribute names can now be arbitrary strings. For instance, - you can write <literal>{ "foo-1.2" = …; "bla bla" = …; }."bla - bla"</literal>.</para> - </listitem> - - <listitem> - <para>Attribute selection can now provide a default value using - the <literal>or</literal> operator. For instance, the expression - <literal>x.y.z or e</literal> evaluates to the attribute - <literal>x.y.z</literal> if it exists, and <literal>e</literal> - otherwise.</para> - </listitem> - - <listitem> - <para>The right-hand side of the <literal>?</literal> operator can - now be an attribute path, e.g., <literal>attrs ? - a.b.c</literal>.</para> - </listitem> - - <listitem> - <para>On Linux, Nix will now make files in the Nix store immutable - on filesystems that support it. This prevents accidental - modification of files in the store by the root user.</para> - </listitem> - - <listitem> - <para>Nix has preliminary support for derivations with multiple - outputs. This is useful because it allows parts of a package to - be deployed and garbage-collected separately. For instance, - development parts of a package such as header files or static - libraries would typically not be part of the closure of an - application, resulting in reduced disk usage and installation - time.</para> - </listitem> - - <listitem> - <para>The Nix store garbage collector is faster and holds the - global lock for a shorter amount of time.</para> - </listitem> - - <listitem> - <para>The option <option>--timeout</option> (corresponding to the - configuration setting <literal>build-timeout</literal>) allows you - to set an absolute timeout on builds — if a build runs for more than - the given number of seconds, it is terminated. This is useful for - recovering automatically from builds that are stuck in an infinite - loop but keep producing output, and for which - <literal>--max-silent-time</literal> is ineffective.</para> - </listitem> - - <listitem> - <para>Nix development has moved to GitHub (<link - xlink:href="https://github.com/NixOS/nix" />).</para> - </listitem> - -</itemizedlist> - -</section> |
