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

Eelco Dolstra e060c99447 Use mkpath instead of make_path
Perl <= 5.10 doesn't have make_path.  See
e.g. http://hydra.nixos.org/build/2493981.

Eelco Dolstra e145ac30e3 Do "make installcheck" for Debian builds 2012-05-01 15:48:17 -04:00
Eelco Dolstra 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.

Eelco Dolstra 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.

Eelco Dolstra 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.

Eelco Dolstra 1132dd27ea Fix obscure race condition in GC root creation
This should fix rare Hydra errors of the form:

Eelco Dolstra 1d0bafb74d Follow redirects early to ensure consistency between the manifest and the tarball
Without this change, if the URL is a redirect that changes in between,
we can get a manifest that doesn't match the tarball.

Eelco Dolstra 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).

Eelco Dolstra 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
a few misbehaved packages.

Eelco Dolstra 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.

Eelco Dolstra 480dda0e42 Delete non-directory valid paths right away
It's unlikely that rename() is faster than unlink() on a regular file
or symlink, so don't bother.

Eelco Dolstra 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.

Eelco Dolstra 8be1979f1a Remove the --max-links GC option
We don't need this anymore now that current filesystems support more
than 32,000 files in a directory.
