373e875ac2 Don't build for old Fedora releases that don't have a sufficiently new SQLite 2012-05-04 17:25:25 -04:00

d03a295192 Require SQLite >= 3.6.19
Nix needs SQLite's foreign key constraint feature, which was
introduced in 3.6.19.  Without it, the database won't be cleaned up
correctly when paths are deleted.  See
e.g. http://hydra.nixos.org/build/2494142.

db5b86ef13 * Add an option ‘build-use-substitutes’, which can be set to ‘false’
to disable use of substitutes; i.e., force building from source.
  Fixes Nix/221.

59a26360c7 Support mandatory system features in the build hook
Mandatory features are features that MUST be present in a derivation's
requiredSystemFeatures attribute.  One application is performance
testing, where we have a dedicated machine to run performance tests
(and nothing else).  Then we would add the label "perf" to the
machine's mandatory features and to the performance testing
derivations.

46cdc6ad51 Handle EPERM when creating a hard link for the chroot
There is a race condition when doing parallel builds with chroots and
the immutable bit enabled.  One process may call makeImmutable()
before the other has called link(), in which case link() will fail
with EPERM.  We could retry or wrap the operation in a lock, but since
this condition is rare and I'm lazy, we just use the existing copy
fallback.

Fixes #9.

we can get a manifest that doesn't match the tarball.

e855c7e2c9 nix-channel improvements
"nix-channel --add" now accepts a second argument: the channel name.
This allows channels to have a nicer name than (say) nixpkgs_unstable.
If no name is given, it defaults to the last component of the URL
(with "-unstable" or "-stable" removed).

Also, channels are now stored in a profile
(/nix/var/nix/profiles/per-user/$USER/channels).  One advantage of
this is that it allows rollbacks (e.g. if "nix-channel --update" gives
an undesirable update).

f2467eb6a0 On Linux, pretend we're building on Linux 2.6
Setting the UNAME26 personality causes "uname" to return "2.6.x",
regardless of the kernel version.  This improves determinism in

5144abe5b6 Add an option "--exclude" to filter dependencies in "nix-build --run-env"
Sometimes when doing "nix-build --run-env" you don't want all
dependencies to be built.  For instance, if we want to do "--run-env"
on the "build" attribute in Hydra's release.nix (to get Hydra's build
environment), we don't want its "tarball" dependency to be built.  So
we can do:

  $ nix-build --run-env release.nix -A build --exclude 'hydra-tarball'

This will skip the dependency whose name matches the "hydra-tarball"
regular expression.  The "--exclude" option can be repeated any number
of times.

480dda0e42 Delete non-directory valid paths right away
It's unlikely that rename() is faster than unlink() on a regular file

117670be57 Make the garbage collector more concurrent
Make the garbage collector more concurrent by deleting valid paths
outside the region where we're holding the global GC lock.  This
should greatly reduce the time during which new builds are blocked,
since the deletion accounts for the vast majority of the time spent in
the GC.

To ensure that this is safe, the valid paths are invalidated and
renamed to some arbitrary path while we're holding the lock.  This
ensures that we when we finally delete the path, it's not a (newly)
valid or locked path.
