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 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:

infinite recursion encountered
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.
- 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.
