2012-04-14 nix-channel improvementsEelco Dolstra6-120/+104
"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).

2012-04-05 On Linux, pretend we're building on Linux 2.6Eelco Dolstra1-0/+11
Setting the UNAME26 personality causes "uname" to return "2.6.x", regardless of the kernel version. This improves determinism in a few misbehaved packages.

If we don't follow redirects, we might think that MANIFEST.bz2 exists just because the HEAD request succeeds on the redirector URI.
2012-03-27 Update "nix-build --help"Eelco Dolstra1-1/+6
2012-03-27 Add an option "--exclude" to filter dependencies in "nix-build --run-env"Eelco Dolstra1-1/+9
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.

2012-03-26 Delete non-directory valid paths right awayEelco Dolstra1-16/+27
It's unlikely that rename() is faster than unlink() on a regular file or symlink, so don't bother.
2012-03-26 Make the garbage collector more concurrentEelco Dolstra3-21/+48
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.
2012-03-26 Remove the --max-links GC optionEelco Dolstra7-30/+3
We don't need this anymore now that current filesystems support more than 32,000 files in a directory.
2012-03-20 nix-store --clear-failed-paths: Clear derivation outputsEelco Dolstra1-1/+3
If the argument to ‘nix-store --clear-failed-paths’ is a derivation, then clear the failed state of its outputs.

2012-03-19 Add a command "nix-build --run-env" to reproduce the environment of a derivationEelco Dolstra3-0/+72
This command builds or fetches all dependencies of the given derivation, then starts a shell with the environment variables from the derivation. This shell also sources $stdenv/setup to initialise the environment further. The current directory is not changed. Thus this is a convenient way to reproduce a build environment in an existing working tree. Existing environment variables are left untouched (unless the derivation overrides them). As a special hack, the original value of $PATH is appended to the $PATH produced by $stdenv/setup. Example session: $ nix-build --run-env '<nixpkgs>' -A xterm (the dependencies of xterm are built/fetched...) $ tar xf $src $ ./configure $ make $ emacs (... hack source ...) $ make $ ./xterm
2012-03-19 Replace "make check" with "make installcheck"Eelco Dolstra8-46/+25
Ensuring that the tests work from the build tree requires a growing number of nasty hacks. The tests also don't verify that the installed Nix actually works. Thus, the tests now require "make install" to have been run.
2012-03-19 Fix the optional dependency on OpenSSLEelco Dolstra1-1/+1

2012-03-18 Drop the externals directoryEelco Dolstra12-181/+66
Nix now requires SQLite and bzip2 to be pre-installed. SQLite is detected using pkg-config. We required DBD::SQLite anyway, so depending on SQLite is not a big problem. The --with-bzip2, --with-openssl and --with-sqlite flags are gone.

2012-03-13 Ensure that Perl processes delete their entry in the temproots directoryEelco Dolstra4-17/+12
By moving the destructor object to libstore.so, it's also run when download-using-manifests and nix-prefetch-url exit. This prevents them from cluttering /nix/var/nix/temproots with stale files.

2012-03-05 nix-copy-closure: don't print copied path on stdoutEelco Dolstra2-2/+2
We're already printing progress on stderr, so printing them on stdout afterwards is kind of useless.

This is useful for debugging.

2012-03-05 build-remote.pl: don't wait forever for the upload lockEelco Dolstra1-3/+17
In the build hook, don't wait forever to get the upload lock. This ensures progress if another process gets stuck while holding the upload lock.
2012-03-01 Remove dependency on sqlite3_table_column_metadataEelco Dolstra1-7/+0
Not all SQLite builds have the function sqlite3_table_column_metadata. We were only using it in a schema upgrade check for compatibility with databases that were probably never seen in the wild. So remove it.
2012-03-01 Fix an uninitialised variableEelco Dolstra1-0/+1
The variable ‘useChroot’ was not initialised properly. This caused random failures if using the build hook. Seen on Mac OS X 10.7 with Clang. Thanks to KolibriFX for finding this :-)
2012-02-18 Fix chroots buildsEelco Dolstra1-0/+16
Chroots are initialised by hard-linking inputs from the Nix store to the chroot. This doesn't work if the input has its immutable bit set, because it's forbidden to create hard links to immutable files. So temporarily clear the immutable bit when creating and destroying the chroot. Note that making regular files in the Nix store immutable isn't very reliable, since the bit can easily become cleared: for instance, if we run the garbage collector after running ‘nix-store --optimise’. So maybe we should only make directories immutable.
2012-02-15 On Linux, make the Nix store really read-only by using the immutable bitEelco Dolstra7-8/+130
I was bitten one time too many by Python modifying the Nix store by creating *.pyc files when run as root. On Linux, we can prevent this by setting the immutable bit on files and directories (as in ‘chattr +i’). This isn't supported by all filesystems, so it's not an error if setting the bit fails. The immutable bit is cleared by the garbage collector before deleting a path. The only tricky aspect is in optimiseStore(), since it's forbidden to create hard links to an immutable file. Thus optimiseStore() temporarily clears the immutable bit before creating the link.
2012-02-15 Fix a broken guard around utime()Eelco Dolstra1-2/+5
Because of an outdated check for a timestamp of 0, we were calling utime() even when it wasn't necessary.
