137 This release has the following improvements:
138 <itemizedlist>
139 <listitem>
140 <para>
141 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.
142 </para>
143 </listitem>
144 <listitem>
145 <para>
146 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:
147<programlisting>
148source $stdenv/setup
149
150postInstall=postInstall
151postInstall() {
152 ln -sf gzip $out/bin/gunzip
153 ln -sf gzip $out/bin/zcat
154}
155
156genericBuild</programlisting>
157 (the <literal>gzip</literal> builder), you can just add this attribute to the derivation:
158<programlisting>
159postInstall = "ln -sf gzip $out/bin/gunzip; ln -sf gzip $out/bin/zcat";</programlisting>
160 and so a separate build script becomes unnecessary. This should allow us to get rid of most builders in Nixpkgs.
161 </para>
162 </listitem>
163 <listitem>
164 <para>
165 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,
166<programlisting>
167configureFlags="CFLAGS=-O0"</programlisting>
168 but not
169<programlisting>
170configureFlags="CFLAGS=-O0 -g"</programlisting>
171 since the <literal>-g</literal> would be interpreted as a separate argument to <command>configure</command>. Now you can say
172<programlisting>
173configureFlagsArray=("CFLAGS=-O0 -g")</programlisting>
174 or similarly
175<programlisting>
176configureFlagsArray=("CFLAGS=-O0 -g" "LDFLAGS=-L/foo -L/bar")</programlisting>
177 which does the right thing. Idem for <literal>makeFlags</literal>, <literal>installFlags</literal>, <literal>checkFlags</literal> and <literal>distFlags</literal>.
178 </para>
179 <para>
180 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.,
181<programlisting>
182configureFlagsArray = ["CFLAGS=-O0 -g"];</programlisting>
183 since it would just be flattened to a since string. However, you <emphasis>can</emphasis> use the inline hooks described above:
184<programlisting>
185preConfigure = "configureFlagsArray=(\"CFLAGS=-O0 -g\")";</programlisting>
186 </para>
187 </listitem>
188 <listitem>
189 <para>
190 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
191<programlisting>
192fetchurl {
193 url = "http://releases.mozilla.org/<replaceable>...</replaceable>/firefox-2.0.0.6-source.tar.bz2";
194 sha1 = "eb72f55e4a8bf08e8c6ef227c0ade3d068ba1082";
195}</programlisting>
196 <function>fetchurl</function> will first try to download this file from <link
197 xlink:href="http://tarballs.nixos.org/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
198 xlink:href="http://tarballs.nixos.org"/>), 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.
199 </para>
200 <para>
201 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:
202<programlisting>
203fetchurl {
204 url = mirror://gnu/gcc/gcc-4.2.0/gcc-core-4.2.0.tar.bz2;
205 sha256 = "0ykhzxhr8857dr97z0j9wyybfz1kjr71xk457cfapfw5fjas4ny1";
206}</programlisting>
207 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.
208<programlisting>
209export NIX_MIRRORS_sourceforge=http://osdn.dl.sourceforge.net/sourceforge/</programlisting>

300 <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.

305 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.

307 <para>
308 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:
309<programlisting>
310{
311 firefox = {
312 enableRealPlayer = true;
313 };
314}</programlisting>
315 persistently enables RealPlayer support in the Firefox build.

However, there is also a standard environment that produces binaries that use <link
328 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>.

378 <para>
379 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 overridden.
380 </para>
381 <para>
382 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:
383<programlisting>
384strategoxt = (import ../development/compilers/strategoxt) {
385 inherit fetchurl pkgconfig sdf aterm;
386 stdenv = overrideInStdenv stdenv [gnumake380];
387};
388
389gnumake380 = <replaceable>...</replaceable>;</programlisting>
390 Likewise, there are many packages that don’t compile with the default GCC (4.1.1), but that’s easily fixed:
391<programlisting>
392exult = import ../games/exult {
393 inherit fetchurl SDL SDL_mixer zlib libpng unzip;
394 stdenv = overrideGCC stdenv gcc34;
395};</programlisting>
396 </para>
397 </listitem>
398 <listitem>
399 <para>
400 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:
401<programlisting>
402pkg = import <replaceable>...</replaceable> {
403 stdenv = stdenv.regenerate ./my-setup.sh;
404 <replaceable>...</replaceable>
405}</programlisting>
406 </para>
407 </listitem>
408 <listitem>
409 <para>
410 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:
411<programlisting>
412stdenv.mkDerivation {
413 name = "exult-1.2";
414 <replaceable>...</replaceable>
415 meta = {
416 description = "A reimplementation of the Ultima VII game engine";
417 };
418}</programlisting>
419 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.).

569 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.

572 This change also makes the bootstrap process faster. For instance, GCC is built only once instead of three times.

580 Tarballs used by Nixpkgs are now obtained from the same server that hosts Nixpkgs (<link
581 xlink:href="http://catamaran.labs.cs.uu.nl/" />). This reduces the risk of packages being unbuildable due to moved or deleted files on various servers.
