<para>Nix supports a new API for building derivations that doesn’t
|
|
|
|
|
|
require a <literal>.drv</literal> file to be present on disk; it
|
|
|
|
|
|
only requires an in-memory representation of the derivation. This
|
|
|
|
|
|
is used by the Hydra continuous build system to make remote builds
|
|
|
|
|
|
more efficient.</para>

<para>The function <literal><nix/fetchurl.nix></literal> now
|
|
|
|
|
|
uses a <emphasis>builtin</emphasis> builder (i.e. it doesn’t
|
|
|
|
|
|
require starting an external process; the download is performed by
|
|
|
|
|
|
Nix itself). This ensures that derivation paths don’t change when
|
|
|
|
|
|
Nix is upgraded, and obviates the need for ugly hacks to support
|
|
|
|
|
|
chroot execution.</para>
