The static curl program is gone, replaced by curl inside of the
bootstrap tools tarball. Also, we generate a .tar.xz archive rather
than .cpio.bz2, making the download smaller. The separate
{sh,cpio,mkdir,ln,bzip2} programs have been replaced by a single
busybox program.
Make thread disabling explicit. This changes the semantics of the perl

This commit doesn't change the derivation or out hash of stdenvLinux.
The stage3.extraAttrs.glibc argument was required for this whole build
procedure to correctly work and it was very-very hard to see why (the
comment said something about gcc47, but we're using gcc48 now).
This stage3.extraAttrs.glibc goes into stage3.stdenv.glibc after some
arg passing, and in pkgs/development/compiler/gcc an (stdenv ? glibc)
boolean expression decides to override /usr/include during the GCC
build.
All of our stages are built with glibc, so this refactoring moves this
repeating specification of glibc (once for gcc wrapper and once here for
extraAttrs) to stageFun, by getting rid of wrapGCC, as we were using
that in all of the stages anyways.
Incidentally it turned out, that this stdenv.glibc inconsistency caused
some random other stuff to behave differently:
- stage1.pkgs.perl has threading disabled,
- stage4.pkgs.coreutils (the production coreutils) has testing disabled.
Leave this historical accidents as they are in this commit, so the scope
of this commit can stay as a refactoring only, these issues will be
fixed in separate commits.

Use the new allowedRequisites feature in stdenvLinux.
This way we properly check that the end-result stdenv of the quite
complicated multi-stage stdenvLinux building procedure is sane, and only
depends on the stuff that we know about.
Alternative would be to just disallowRequisites bootstrapTools, which is
the most common offender, but we have had other offenders in the past.
For these checks to actually fire, you currently have to use nixUnstable,
as the necessary feature will be released in Nix 1.8.
Previously stdenv depended on two different zlibs and there was a third
one in the top-level package set for other purposes. This commit merges
all this zlibs to one.
Actually this have been committed once as 1f2b636, but then got lost
while resolving merge conflicts. Hopefully it survives this time.
The point here is that it's always possible to debug this staging
logic by using `nix-repl pkgs/stdenv/linux'. The modular-stdenv
change introduced the lib dependency, which we now default to
../../../lib.
No derivation or out hashes of stdenvLinux is changed by this commit.

Commit 986f361946 started to use
<nix/fetchurl.nix> to "download" the bootstrap binaries from the
Nixpkgs tree, using the file:/// scheme. This has really bad
consequences:
* It makes any derivation depend on the path of the Nixpkgs tree. So
evaluating a package will produce a different .drv file when run
from different locations. No wonder Hydra evaluation has been so
slow lately: for every Nixpkgs evaluation, it had to create tens of
thousands of .drv files, even if nothing had changed.
* It requires the builder to have file system access to the Nixpkgs
tree. So if your tree is in your home directory, the stdenv
bootstrap would probably fail.
So now the binaries are downloaded from tarballs.nixos.org.
Also dropped PowerPC "support".
Binutils nowadays contains ld.gold, which depends on libstdc++. So it
needs to be built with the new GCC rather than the one from
bootstrap-tools.
Issue #1469.
GCC provides a number of libraries that are used by programs built by
GCC, in particular libgcc_s.so and libstdc++.so. This caused programs
that used these libraries to have a runtime dependency on all of GCC
(~77 MiB). Now they only depend on the "lib" output of GCC (~1.6
MiB).
With this and previous multiple-output improvements, closure sizes are
reduced a lot:
hello: 41 MiB -> 22 MiB
patchelf: 118 MiB -> 23 MiB
pan: 364 MiB -> 90 MiB
This reduces the size of closures a lot by getting rid of Glibc's
header files, static libraries and utilities. For instance, the
closure of GNU Hello went from 41 MiB to 22 MiB.
TODO: We may want to merge back in parts of Glibc that we previously
split off (such as the info files).
Since nix-1.4, nix's corepkgs contain a fetchurl suitable for
downloading the bootstrap binaries. Doing this will allow us to have a
nixpkgs with no in-tree binaries without breaking the purity of the
bootstrap (though for now, they are fetched in-tree until the binaries
are added to nixos.org somewhere). As an additional small benefit, the
in-tree binaries do not have to be hashed on every instantiation as they
do now.
The fetchurl in nix-1.2 and 1.3 isn't able to make binaries executable,
so it can't be used for this case. In that case, attempting to build the
bootstrap will show a message asking the user to manually download each
file and add it to the store with nix-store --add (but the hash is
ultimately the same, of course).

Due to xz being override in the last stdenv and also in the previous, the
nixpkgs xz ended up being built by bootstrap-tools, and thus depending on it
through libgcc_so.so.1. That ends up making 'nix' with a runtime
dependency on bootstrap-tools.
Although patching it made some programs run (configure tests), some others
crashed with segfault. So I don't think there is any win patching it. The
proper way to solve the bootstrap in the raspberry pi is, as far as I've been
testing, use glibc 2.17 libs in bootstrap-tools with the same ld.so name as the
bootstrapped glibc.
This is a problem inherent in our way to bootstrap, that first replaces
the glibc of a given gcc+glibc (bootstrap-tools) with gcc-wrapper tricks, and
then builds a new gcc. A nicer way would be to build a gcc without glibc,
then the glibc, then the final gcc, as we do with cross-tools.
Some comments about this problem in
https://github.com/NixOS/nixpkgs/issues/234#issuecomment-11764352
This solves the problem of the change of name in ld.so between
glibc 2.13 and 2.17 (at least for armhf). Some comments about it in
https://github.com/NixOS/nixpkgs/issues/234#issuecomment-11764352
As there says, without this, gmp (after glibc built) tests crashed
- segfault.
Now that we have a way to alter /bin/sh in chroots on non-NixOS Linux
platforms, it may be useful to have access to stdenv.shell package and to
static bash contained in bootstrap tools. So make them accessible via stdenv
attribute set.
libstdc++ and libmudflapth link to the dynamic loader; if the
bootstrap uses another dynamic loader name, and the rpath of these
libs isn't changed, they will fail to load.
Conflicts:
pkgs/development/compilers/gcc/4.6/default.nix
pkgs/development/compilers/gcc/4.7/default.nix
The 4.7 had some weird parameters added in crossAttrs; I've removed
them, but I don't understand where they come from.
This allows various applications. It allows users to set global
optimisation flags, e.g.
stdenv.userHook = ''NIX_CFLAGS_COMPILE+=" -funroll-loops"'';
But the impetus is as an alternative to issue #229, allowing impure
stdenv setup for people who want to use distcc:
stdenv.userHook = "source /my/impure/setup-script.sh";
This is probably a bad idea, but at least now it's a bad idea in
people's configuration and not in Nixpkgs. :-)
what the new nix thinks the fuloong is.
Anyone having the old nix should use a nixpkgs previous to this change to build
the new nix. And then, with the new nix, he can use any newer nixpkgs revision.

I updated some days ago the x86_64-linux bootstrap-tools, but that update is
not needed anymore. We can revert that boostrap-tools update if anyone wants.
Pro:
- new gcc building gcc and glibc.
Contra:
- maybe some old systems (patched red had kernels come to mind) break with that update?

the cross compilation functionality.
- I renamed some expected stdenv.mkDerivation parameter attributes so we can
keep this branch properly updated from trunk. We agreed with Nicolas Pierron
doing a massive renaming, so all current buildInputs become hostInputs (input
as build for the host machine, in autotools terminology) , and
then buildInputs would mean "input as for the build machine".
By now, the specific "input as for the build machine" is specified through
buildNativeInputs. We should fix this in the merge to trunk.
- I made the generic stdenv understand the buildNativeInputs, otherwise if
we start changing nixpkgs expressions so they distinguish the current
buildInputs into buildInputs and buildNativeInputs, we could break even more
nixpkgs for other platforms.
- I changed the default result of mkDerivation so it becomes the derivation for
to be run in the build machine. This allows, without any special rewriting,
"fetchurl" derivations to be always results for the build machine to use
them.
- The change above implies that, for anyone wanting to cross-compile, has to
build the hostDrv of the wanted derivation. For example, after this commit,
the usual test of "nix-build -A bison.hostDrv arm.nix" works. I described
the contents of this arm.nix in r18398.

It still does not work, but I think I already get glibc cross compiled.
Next: gcc and g++, and set some setup script hooks on stdenvCross.
It took quite enough hours for this commit.
svn path=/nixpkgs/branches/stdenv-updates/; revision=18351
My idea is to provide special stdenv expressions that will contain in the path
additional cross compilers. As most expressions for programs accept a stdenv parameter,
we could substitute this parameter with the special stdenv, which will have a
generic builder that attempts the usual "--target=..." and can additionally
have an env variable like "cross" with the target architecture set.
So, finally we could have additional expressions like this:
bashRealArm = makeOverridable (import ../shells/bash) {
inherit fetchurl bison;
stdenv = stdenvCross "armv5tel-unknown-linux-gnueabi";
};
Meanwhile it does not work - I still cannot get the cross-gcc to build.
I think it does not fill the previous expressions with a lot of noise, so I
think it may be a good path to follow.
I only touched some files of the current stdenv: gcc-4.3, kernel headers
2.6.28, glibc 2.9, ...
I tried to use the gcc-cross-wrapper, that may be very outdated. Maybe I will
update it, or update the gcc-wrapper expression to make it fit the cross tools,
but meanwhile I even cannot build gcc, so I have not tested the wrapper.
This new idea on cross compiling is not similar to that of the
nixpkgs/branches/cross-compilation, which mostly added bare new expressions for
anything to be cross compiled, if I understood it correctly.
I cared not to break anything of the usual stdenv in all this work.
