<title>Nixpkgs Release Notes</title>
|
||
|
||
|
||
<section><title>Release 0.11 (September 11, 2007)</title>
|
||
|
||
<para>This release has the following improvements:
|
||
|
||
<itemizedlist>
|
||
|
||
|
||
<listitem><para>The standard build environment
|
||
(<literal>stdenv</literal>) is now pure on the
|
||
<literal>x86_64-linux</literal> and <literal>powerpc-linux</literal>
|
||
platforms, just as on <literal>i686-linux</literal>. (Purity means
|
||
that building and using the standard environment has no dependencies
|
||
outside of the Nix store. For instance, it doesn’t require an
|
||
external C compiler such as <filename>/usr/bin/gcc</filename>.)
|
||
Also, the statically linked binaries used in the bootstrap process
|
||
are now automatically reproducible, making it easy to update the
|
||
bootstrap tools and to add support for other Linux platforms. See
|
||
<filename>pkgs/stdenv/linux/make-bootstrap-tools.nix</filename> for
|
||
details.</para></listitem>
|
||
|
||
|
||
<listitem><para>Hook variables in the generic builder are now
|
||
executed using the <function>eval</function> shell command. This
|
||
has a major advantage: you can write hooks directly in Nix
|
||
expressions. For instance, rather than writing a builder like this:
|
||
|
||
<programlisting>
|
||
source $stdenv/setup
|
||
|
||
postInstall=postInstall
|
||
postInstall() {
|
||
ln -sf gzip $out/bin/gunzip
|
||
ln -sf gzip $out/bin/zcat
|
||
}
|
||
|
||
genericBuild</programlisting>
|
||
|
||
(the <literal>gzip</literal> builder), you can just add this
|
||
attribute to the derivation:
|
||
|
||
<programlisting>
|
||
postInstall = "ln -sf gzip $out/bin/gunzip; ln -sf gzip $out/bin/zcat";</programlisting>
|
||
|
||
and so a separate build script becomes unnecessary. This should
|
||
allow us to get rid of most builders in Nixpkgs.</para></listitem>
|
||
|
||
|
||
<listitem><para>It is now possible to have the generic builder pass
|
||
arguments to <command>configure</command> and
|
||
<command>make</command> that contain whitespace. Previously, for
|
||
example, you could say in a builder,
|
||
|
||
<programlisting>
|
||
configureFlags="CFLAGS=-O0"</programlisting>
|
||
|
||
but not
|
||
|
||
<programlisting>
|
||
configureFlags="CFLAGS=-O0 -g"</programlisting>
|
||
|
||
since the <literal>-g</literal> would be interpreted as a separate
|
||
argument to <command>configure</command>. Now you can say
|
||
|
||
<programlisting>
|
||
configureFlagsArray=("CFLAGS=-O0 -g")</programlisting>
|
||
|
||
or similarly
|
||
|
||
<programlisting>
|
||
configureFlagsArray=("CFLAGS=-O0 -g" "LDFLAGS=-L/foo -L/bar")</programlisting>
|
||
|
||
which does the right thing. Idem for <literal>makeFlags</literal>,
|
||
<literal>installFlags</literal>, <literal>checkFlags</literal> and
|
||
<literal>distFlags</literal>.</para>
|
||
|
||
<para>Unfortunately you can't pass arrays to Bash through the
|
||
environment, so you can't put the array above in a Nix expression,
|
||
e.g.,
|
||
|
||
<programlisting>
|
||
configureFlagsArray = ["CFLAGS=-O0 -g"];</programlisting>
|
||
|
||
since it would just be flattened to a since string. However, you
|
||
<emphasis>can</emphasis> use the inline hooks described above:
|
||
|
||
<programlisting>
|
||
preConfigure = "configureFlagsArray=(\"CFLAGS=-O0 -g\")";</programlisting>
|
||
|
||
</para></listitem>
|
||
|
||
|
||
<listitem><para>The function <function>fetchurl</function> now has
|
||
support for two different kinds of mirroring of files. First, it
|
||
has support for <emphasis>content-addressable mirrors</emphasis>.
|
||
For example, given the <function>fetchurl</function> call
|
||
|
||
<programlisting>
|
||
fetchurl {
|
||
url = http://releases.mozilla.org/<replaceable>...</replaceable>/firefox-2.0.0.6-source.tar.bz2;
|
||
sha1 = "eb72f55e4a8bf08e8c6ef227c0ade3d068ba1082";
|
||
}</programlisting>
|
||
|
||
<function>fetchurl</function> will first try to download this file
|
||
from <link
|
||
xlink:href="http://nix.cs.uu.nl/dist/tarballs/sha1/eb72f55e4a8bf08e8c6ef227c0ade3d068ba1082"/>.
|
||
If that file doesn’t exist, it will try the original URL. In
|
||
general, the “content-addressed” location is
|
||
<replaceable>mirror</replaceable><literal>/</literal><replaceable>hash-type</replaceable><literal>/</literal><replaceable>hash</replaceable>.
|
||
There is currently only one content-addressable mirror (<link
|
||
xlink:href="http://nix.cs.uu.nl/dist/tarballs"/>), but more can be
|
||
specified in the <varname>hashedMirrors</varname> attribute in
|
||
<filename>pkgs/build-support/fetchurl/mirrors.nix</filename>, or by
|
||
setting the <envar>NIX_HASHED_MIRRORS</envar> environment variable
|
||
to a whitespace-separated list of URLs.</para>
|
||
|
||
<para>Second, <function>fetchurl</function> has support for
|
||
widely-mirrored distribution sites such as SourceForge or the Linux
|
||
kernel archives. Given a URL of the form
|
||
<literal>mirror://<replaceable>site</replaceable>/<replaceable>path</replaceable></literal>,
|
||
it will try to download <replaceable>path</replaceable> from a
|
||
configurable list of mirrors for <replaceable>site</replaceable>.
|
||
(This idea was borrowed from Gentoo Linux.) Example:
|
||
<programlisting>
|
||
fetchurl {
|
||
url = mirror://gnu/gcc/gcc-4.2.0/gcc-core-4.2.0.tar.bz2;
|
||
sha256 = "0ykhzxhr8857dr97z0j9wyybfz1kjr71xk457cfapfw5fjas4ny1";
|
||
}</programlisting>
|
||
Currently <replaceable>site</replaceable> can be
|
||
<literal>sourceforge</literal>, <literal>gnu</literal> and
|
||
<literal>kernel</literal>. The list of mirrors is defined in
|
||
<filename>pkgs/build-support/fetchurl/mirrors.nix</filename>. You
|
||
can override the list of mirrors for a particular site by setting
|
||
the environment variable
|
||
<envar>NIX_MIRRORS_<replaceable>site</replaceable></envar>, e.g.
|
||
<programlisting>
|
||
export NIX_MIRRORS_sourceforge=http://osdn.dl.sourceforge.net/sourceforge/</programlisting>

<itemizedlist>
|

|

<listitem><para><filename>pkgs/system/all-packages-generic.nix</filename>
|
||
is gone, we now just have
|
||
<filename>pkgs/top-level/all-packages.nix</filename> that contains
|
||
all available packages. This should cause much less confusion with
|
||
users. <filename>all-packages.nix</filename> is a function that by
|
||
default returns packages for the current platform, but you can
|
||
override this by specifying a different <varname>system</varname>
|
||
argument.</para></listitem>
|
||
|
||
<listitem><para>Certain packages in Nixpkgs are now
|
||
user-configurable through a configuration file, i.e., without having
|
||
to edit the Nix expressions in Nixpkgs. For instance, the Firefox
|
||
provided in the Nixpkgs channel is built without the RealPlayer
|
||
plugin (for legal reasons). Previously, you could easily enable
|
||
RealPlayer support by editing the call to the Firefox function in
|
||
<filename>all-packages.nix</filename>, but such changes are not
|
||
respected when Firefox is subsequently updated through the Nixpkgs
|
||
channel.</para>
|
||
|
||
<para>The Nixpkgs configuration file (found in
|
||
<filename>~/.nixpkgs/config.nix</filename> or through the
|
||
<envar>NIXPKGS_CONFIG</envar> environment variable) is an attribute
|
||
set that contains configuration options that
|
||
<filename>all-packages.nix</filename> reads and uses for certain
|
||
packages. For instance, the following configuration file:
|
||
|
||
<programlisting>
|
||
{
|
||
firefox = {
|
||
enableRealPlayer = true;
|
||
};
|
||
}</programlisting>
|
||
|
||
persistently enables RealPlayer support in the Firefox
|
||
build.</para>
|
||
|
||
<para>(Actually, <literal>firefox.enableRealPlayer</literal> is the
|
||
<emphasis>only</emphasis> configuration option currently available,
|
||
but more are sure to be added.)</para></listitem>

The standard environment on <literal>i686-cygwin</literal> by
|
||
default builds binaries for the Cygwin environment (i.e., it

uses Cygwin tools and produces executables that use the Cygwin

||
library). However, there is also a standard environment that
|
||
produces binaries that use <link
|
||
xlink:href="http://www.mingw.org/">MinGW</link>. You can use it
|
||
by calling <filename>all-package.nix</filename> with the

<varname>stdenvType</varname> argument set to

<literal>"i686-mingw"</literal>.</para></listitem>

</itemizedlist>
|

|

In total there are now around 809 packages in Nixpkgs.</para>
|
||
|
||
</listitem>
|
||
|
||
|
||
<listitem><para>It is now <emphasis>much</emphasis> easier to
|
||
override the default C compiler and other tools in
|
||
<literal>stdenv</literal> for specific packages.
|
||
<filename>all-packages.nix</filename> provides two utility
|
||
functions for this purpose: <function>overrideGCC</function> and
|
||
<function>overrideInStdenv</function>. Both take a
|
||
<literal>stdenv</literal> and return an augmented
|
||
<literal>stdenv</literal>; the formed changes the C compiler, and
|
||
the latter adds additional packages to the front of
|
||
<literal>stdenv</literal>’s initial <envar>PATH</envar>, allowing
|
||
tools to be overriden.</para>
|
||
|
||
<para>For instance, the package <varname>strategoxt</varname>
|
||
doesn’t build with the GNU Make in <literal>stdenv</literal>
|
||
(version 3.81), so we call it with an augmented
|
||
<literal>stdenv</literal> that uses GNU Make 3.80:
|
||
|
||
<programlisting>
|
||
strategoxt = (import ../development/compilers/strategoxt) {
|
||
inherit fetchurl pkgconfig sdf aterm;
|
||
stdenv = overrideInStdenv stdenv [gnumake380];
|
||
};
|
||
|
||
gnumake380 = <replaceable>...</replaceable>;</programlisting>
|
||
|
||
Likewise, there are many packages that don’t compile with the
|
||
default GCC (4.1.1), but that’s easily fixed:
|
||
|
||
<programlisting>
|
||
exult = import ../games/exult {
|
||
inherit fetchurl SDL SDL_mixer zlib libpng unzip;
|
||
stdenv = overrideGCC stdenv gcc34;
|
||
};</programlisting>
|
||
|
||
</para></listitem>
|
||
|
||
|
||
<listitem><para>It has also become much easier to experiment with
|
||
changes to the <literal>stdenv</literal> setup script (which notably
|
||
contains the generic builder). Since edits to
|
||
<filename>pkgs/stdenv/generic/setup.sh</filename> trigger a rebuild
|
||
of <emphasis>everything</emphasis>, this was formerly quite painful.
|
||
But now <literal>stdenv</literal> contains a function to
|
||
“regenerate” <literal>stdenv</literal> with a different setup
|
||
script, allowing the use of a different setup script for specific
|
||
packages:
|
||
|
||
<programlisting>
|
||
pkg = import <replaceable>...</replaceable> {
|
||
stdenv = stdenv.regenerate ./my-setup.sh;
|
||
<replaceable>...</replaceable>
|
||
}</programlisting>
|
||
|
||
</para></listitem>
|
||
|
||
|
||
<listitem><para>Packages can now have a human-readable
|
||
<emphasis>description</emphasis> field. Package descriptions are
|
||
shown by <literal>nix-env -qa --description</literal>. In addition,
|
||
they’re shown on the Nixpkgs release page. A description can be
|
||
added to a package as follows:
|
||
|
||
<programlisting>
|
||
stdenv.mkDerivation {
|
||
name = "exult-1.2";
|
||
<replaceable>...</replaceable>
|
||
meta = {
|
||
description = "A reimplementation of the Ultima VII game engine";
|
||
};
|
||
}</programlisting>
|
||
|
||
The <varname>meta</varname> attribute is not passed to the builder,
|
||
so changes to the description do not trigger a rebuild. Additional
|
||
<varname>meta</varname> attributes may be defined in the future
|
||
(such as the URL of the package’s homepage, the license,
|
||
etc.).</para></listitem>

<para>The bootstrap process for the standard build
|
||
environment on Linux (stdenv-linux) has been improved. It is no
|
||
longer dependent in its initial bootstrap stages on the system
|
||
Glibc, GCC, and other tools. Rather, Nixpkgs contains a statically
|
||
linked bash and curl, and uses that to download other statically
|
||
linked tools. These are then used to build a Glibc and dynamically
|
||
linked versions of all other tools.</para>
|
||
|
||
<para>This change also makes the bootstrap process faster. For
|
||
instance, GCC is built only once instead of three times.</para>

risk of packages being unbuildable due to moved or deleted files on
