Namely: - <itemizedlist> - <listitem><para>The private network namespace ensures that - builders cannot talk to the outside world (or vice versa): each - build only sees a private loopback interface. This also means - that two concurrent builds can listen on the same port (e.g. as - part of a test) without conflicting with each - other.</para></listitem> - <listitem><para>The PID namespace causes each build to start as - PID 1. Processes outside of the chroot are not visible to those - on the inside. On the other hand, processes inside the chroot - <emphasis>are</emphasis> visible from the outside (though with - different PIDs).</para></listitem> - <listitem><para>The IPC namespace prevents the builder from - communicating with outside processes using SysV IPC mechanisms - (shared memory, message queues, semaphores). It also ensures - that all IPC objects are destroyed when the builder - exits.</para></listitem> - <listitem><para>The UTS namespace ensures that builders see a - hostname of <literal>localhost</literal> rather than the actual - hostname.</para></listitem> - <listitem><para>The private mount namespace was already used by - Nix to ensure that the bind-mounts used to set up the chroot are - cleaned up automatically.</para></listitem> - </itemizedlist> - </para> - </listitem> - - <listitem> - <para>Build logs are now compressed using - <command>bzip2</command>. The command <command>nix-store - -l</command> decompresses them on the fly. This can be disabled - by setting the option <literal>build-compress-log</literal> to - <literal>false</literal>.</para> - </listitem> - - <listitem> - <para>The creation of build logs in - <filename>/nix/var/log/nix/drvs</filename> can be disabled by - setting the new option <literal>build-keep-log</literal> to - <literal>false</literal>. This is useful, for instance, for Hydra - build machines.</para> - </listitem> - - <listitem> - <para>Nix now reserves some space in - <filename>/nix/var/nix/db/reserved</filename> to ensure that the - garbage collector can run successfully if the disk is full. This - is necessary because SQLite transactions fail if the disk is - full.</para> - </listitem> - - <listitem> - <para>Added a basic <function>fetchurl</function> function. This - is not intended to replace the <function>fetchurl</function> in - Nixpkgs, but is useful for bootstrapping; e.g., it will allow us - to get rid of the bootstrap binaries in the Nixpkgs source tree - and download them instead. You can use it by doing - <literal>import <nix/fetchurl.nix> { url = - <replaceable>url</replaceable>; sha256 = - "<replaceable>hash</replaceable>"; }</literal>.
