Before this commit, if a haskell library X depends on Y, and X was added to
systemPackages, only X would be available in the user environment. Y
would not be avialable, which causes X to be broken. This commit solves
the issue by setting propagatedUserEnvPkgs to all packages X depends
on when X is a library.
This adds nix-run, which is a thin wrapper around nix-build.
nix-run calls nix-build, and then executes the resulting build.
If no executable artifact is built, nix-runs outputs an error
message.
myEnvRun calls myEnvFun and builds a script that directly runs
the load-env-* script.
Together, nix-run and myEnvRun allows you to set up an environment
that can be loaded in this way:
envs.nix:
{
gcc = myEnvRun {
name = "gcc";
buildInputs = [ gcc ];
};
}
$ nix-run -A gcc envs.nix
You end up directly in your environment without having to do
nix-env -i. You will always have a fresh environment and you
don't have to pollute you profile with a lot of env packages.
The nix-prefect git script was broken when trying to parse certain
groups of submodules. This patch fixes the url detection for submodule
repositories to use the more reliable `git config` commands.
* There now is full support for building Haskell packages as shared libraries
for GHC versions 7.4.2 or later. The Cabal builder recognizes the following
attributes:
- enableSharedLibraries configures Cabal to build of shared libraries in
addition to static ones. This option requires that all dependencies of
the package have been compiled for use in shared libraries, too.
- enableSharedExecutables configures Cabal to prefer shared libraries when
linking executables.
The default values for these attributes are arguments to the haskellPackages
expression.
* Haskell builds now run in a LANG="en_US.UTF-8" environment to avoid plenty
of build and test suite errors. Without this setting, GHC seems unable to
deal with the UTF-8 character encoding that's generally considered standard
in the Haskell world.
* The Cabal builder supports a new attribute 'testTarget' to specify the exact
set of tests to be run during the check phase.
* The ghc-wrapper attribute ghcVersion has been removed. Instead, we use the
ghc.version attribute, which exists in unwrapped GHC derivations, too.
The default target (i386-linux) causes flags like "-march i386" to be
added, which breaks on recent Fedora releases (18 and up), resulting
in errors like:
/usr/lib/gcc/i686-redhat-linux/4.7.2/../../../../include/c++/4.7.2/ext/atomicity.h:48: undefined reference to `__atomic_fetch_add_4'
So set the target to i686-linux.
http://hydra.nixos.org/build/6567357
We cannot pass the --{enable,disable}-executable-dynamic flags to GHC
versions prior to 7.4.x.
Building shared libraries via --{enable,disable}-shared is possible in theory
with GHC 6.12.x or later, but doesn't work in practice because our GHC 6.10.x
builds don't provide shared versions of their base libraries. This could
probably be fixed, but it's probably not worth the effort.
enableSharedLibraries configures Cabal to build of shared libraries. This
option requires that all dependencies of the package have been compiled
for use in shared libraries, too.
enableSharedExecutables configures Cabal to prefer shared libraries when
linking executables.
This patch partly fixes issue #1084.
Kept the old hacks where they don't break the build in case they things
they fix are still relevant.
I checked that the upgrade doesn't break:
1) Asymptote and EProver builds.
2) My XeLaTeX demo from configurations/ repository.
3) Some of my own files.
The upgrade fixes problems with simultaneous use of 3D and LaTeX labels
in Asymptote.
Please provide a test that worked previously and is broken now if you
need to revert this update or its parts.
The dns packages requires this feature, because it ships two test programs: one
of them requires network access (so we cannot run it), but the other test does
not. Setting testTarget appropriately allows us to run only one of the two
suites.
Haskell packages that contain non-ascii characters in their .cabal file
or somewhere else in their haddock documentation fail to compile under
nixpkgs and usually flagged with noHaddock = true. I wanted to do the
same for modularArithmentic, when I realized that we just have to set
the locale to some UTF-8 compatible locale in build-support/cabal to fix
this issue correctly.
Wheezy has been released on June 15th and on all mirrors the SHA256 hash
of Packages.bz2 has changed to reflect the new release, so let's update.
Here is the release announcement from Debian:
http://www.debian.org/News/2013/20130615
It also seems that the versioning scheme has changed in version 7.x, so
they seem to have switched to a two digit versioning scheme. This means,
that the attribute name "debian70..." should really be something like
"debian7...", but I'm keeping the attribute as-is to not break
references.

9p (with caching enabled) is much faster than CIFS and doesn't require
Samba or virtual networking. For instance, building GNU Hello with
CIFS takes ~323s on my laptop, but with 9p it takes 54s.
More measurements will be needed to see if "cache=fscache" is really
faster than "cache=loose" (the former seems to be a little bit
faster).
This only ever worked because runInLinuxVM happened to call
overrideDerivation, which itself erroneously passed arbitrarily-added
attributes to the new call to derivation.
Hopefully this time Eelco won't have to revert my change ;)

The wrapper script accumulated some cruft over the last couple of months
because we did changes in freaky ways to avoid triggering re-builds of all
Haskell packages. Most of these kludges have been thrown out now.
This patch doesn't change the behavior of the wrapper except for one thing: the
internal helper scripts "ghc-get-packages.sh" and "ghc-packages.sh" are no
longer installed in the bin directory of the generated derivation.
The previous implementation used the following tying-the-knot trickery to
override 'doCheck' to false for the given build:
cabalNoTest = {
mkDerivation = x: rec {
final = self.cabal.mkDerivation (self: (x final) // { doCheck = false; });
}.final;
};
That seemed to work, but for some reason it caused trouble with some builds --
not all -- that use jailbreakCabal. The problem was the 'stdenv' attribute
couldn't be evaluated properly anymore:

I tried to figure out why this happens, but eventually gave up. The new
implementation passes an argument called 'enableCheckPhase' to the Cabal
builder, which determines whether the user-specified doCheck value has any
effect or not. Now, a normal override can be used to disable unit testing.
It's quite amazing that we've managed to pass incorrectly spelled command line
flags to Cabal for ages without ever noticing. :-)
The search path options --extra-{include,lib}-dirs are usually unnecessary,
because the build environment is set up such that gcc and ld find those headers
and libraries automatically, i.e. without needing extra flags. The bubble burst
on MacOS X, though, where the build of haskell-text-icu couldn't find the icu
library without manually setting DYLD_LIBRARY_PATH in that build. Fortunately,
cabal takes care of that issue if a correctly spelled --extra-lib-dirs flag is
passed.
- The option for cloning in nix-prefetch-bzr is removed
- ssl certificates are now ignored by fetchbzr
This means that no .bzr directory is downloaded. Without this change, the
hash of the result is unpredictable, probably because of timestamping in the
.bzr directory.
Currently, the only package using fetchbzr is kicad.
There are some SVN repositories out there which don't have revision information
tied to externals. By using ignoreExternals, fetchsvn won't fetch these
externals anymore, so the fetch won't fail with a checksum mismatch, should
there be some changes in some of those external repositories.

An aggregate is a trivial build that depends on other builds. This is
intended to provide a declarative replacement of Hydra's "view"
mechanism.
For instance, you can define an aggregate named "critical" that
depends on a selected set of jobs:
critical = releaseTools.aggregate
{ name = "foo-${tarball.version}";
members =
[ tarball
build.x86_64-linux
...
];
meta.description = "Release-critical builds";
};
The "critical" build will only succeed if all its members
(dependencies) succeed.

This branch refactors xfce and updates it to 4.10. I had been hoping to
find someone besides Vlada to test this (I don't use xfce), but no one
has come forward yet in 2 weeks so if this breaks something they can
make an issue or fix it. It all looks good by inspection.
According to <http://hackage.haskell.org/trac/ghc/ticket/4013>, this
feature won't work with XCode versions older than 3.2.
This means that Mac users will have considerably larger binaries because
some build-time dependencies (such as HTTP) will be mis-detected as
run-time dependencies.
In the master branch, doCheck defaults to 'false', which means that no package
will change its hash unless its doCheck field is set to 'true' explicitly. In
the stdenv-updates branch, however, all Haskell packages have a default setting
of 'doCheck=true'. Once that branch has been merged, filtering doCheck is no
longer necessary.

Merge conflicts seemed trivial, but a look from viric and aszlig would be nice.
This patch configures all Cabal builds with '--enable-split-objs' unless the
Nix expression explicitly sets "enableSplitObjs = false". The Cabal manual [1]
describes this option as follows:
| The GHC -split-objs reduces the final size of the executables that use the
| library by allowing them to link with only the bits that they use rather
| than the entire library. The downside is that building the library takes
| longer and uses considerably more memory.
One immediate benefit of this change is that the 'darcs' closure defined in the
top-level no longer refers to GHC. The same is probably true with other
executable packages.

The use case is to do a deep replacement of a dependency without rebuilding the entire tree.
For example, suppose a security hole is found in glibc and a patch released. Ideally, you'd
just rebuild everything, but that takes time, space, and CPU that you might not have, so in
the mean time you could build a safe version of, say, firefox with:
firefox-safe = replace-dependency { drv = firefox; old-dependency = glibc; new-dependency = patched-glibc; };
Building firefox-safe will rebuild glibc, but only do a simple copy/string replacement on all other dependencies
of firefox. On my system (MBP 13" mid-2012), after a new glibc had been build building firefox took around 11 seconds.
See the comments in the file for more details.

The 4.7 had some weird parameters added in crossAttrs; I've removed
them, but I don't understand where they come from.
This is for consistency with terminology in stdenv (and the terms
"hostDrv" and "buildDrv" are not very intuitive, even if they're
consistent with GNU terminology).
Added support code for comfortable writing of upstream data update
expressions that do not require change of layout of the updated
expressions (although they make assumptions about single assignment per
line). Also added a default for choosing file to update (it is supposed
to be default.nix in the same directory) and a one-liner for typical
sourceforge redirects (and sourceforge mirror:// handling).
Replacing SBCL upstream tracking expression with a new version in a new
format.
Minuses: gave up on defining everything in Nix language (now update
expression is a series of actions to do when downloading fresh release,
it is actually interpreted by shell), now Nix expression contains
meaningful whitespace (the area to regenerate is determined by the
line with a specific comment and the closing brace on the otherwise
empty line).
Plusses: only one extra file which could even be moved out-of-tree if
desired, clean semantics for traversing multiple links (it is not found
in either Debian uscan or Gentoo euscan), the main expression is in one
file and is less different from usual style.
Jailbreaks-cabal allows Nixpkgs maintainers to quick-fix builds of packages
that over-specify their version requirements by removing the version
restrictions of all dependencies from the Cabal file. Set
jailbreak = true
in the build expression to activate this feature.
