2012-04-30	* Add an option ‘build-use-substitutes’, which can be set to ‘false’	Eelco Dolstra	5	-4/+14
	to disable use of substitutes; i.e., force building from source. Fixes Nix/221.
2012-04-30	Handle EPERM when creating a hard link for the chroot	Eelco Dolstra	1	-2/+5
	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.
2012-04-23	Merge pull request #2 from viric/master	Eelco Dolstra	1	-0/+6
	Again, adding the sync option
2012-04-17	nix-instantiate: default to "default.nix" if no arguments are given	Eelco Dolstra	1	-1/+2

2012-04-17	Added utility command ‘nix-instantiate --find-file’ to look up a file in ↵	Eelco Dolstra	1	-0/+12
	Nix's search path
2012-04-16	Fix obscure race condition in GC root creation	Eelco Dolstra	1	-16/+18
	This should fix rare Hydra errors of the form: error: symlinking `/nix/var/nix/gcroots/per-user/hydra/hydra-roots/7sfhs5fdmjxm8sqgcpd0pgcsmz1kq0l0-nixos-iso-0.1pre33785-33795' to `/nix/store/7sfhs5fdmjxm8sqgcpd0pgcsmz1kq0l0-nixos-iso-0.1pre33785-33795': File exists
2012-04-15	Set a few more close-on-exec flags	Eelco Dolstra	1	-0/+4

2012-04-15	Close almost all file descriptors in the builder	Eelco Dolstra	1	-0/+3
	This regression was accidentally introduced in 35355fc1fcffbe859395e360c0a6a1463f137d63.
2012-04-14	Remove unnecessary "system" argument	Eelco Dolstra	1	-1/+0

2012-04-13	Use Bison 2.5	Eelco Dolstra	1	-0/+2

2012-04-05	On Linux, pretend we're building on Linux 2.6	Eelco Dolstra	1	-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.
2012-04-04	Include --keep-going in --help	Eelco Dolstra	2	-0/+4

2012-03-26	Mac OS X fix	Eelco Dolstra	1	-0/+3

2012-03-26	Delete non-directory valid paths right away	Eelco Dolstra	1	-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 concurrent	Eelco Dolstra	3	-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 option	Eelco Dolstra	6	-19/+3
	We don't need this anymore now that current filesystems support more than 32,000 files in a directory.
2012-03-22	Fixing the default of sync-before-registering	Lluís Batlle i Rossell	1	-1/+5
	Setting 'false' as default, as suggested by Eelco. I also added a comment about the setting in the code.
2012-03-22	Adding a nix option to sync before registering a path, for non-ext*	Lluís Batlle i Rossell	1	-0/+2
	filesystems.
2012-03-20	nix-store --clear-failed-paths: Clear derivation outputs	Eelco Dolstra	1	-1/+3
	If the argument to ‘nix-store --clear-failed-paths’ is a derivation, then clear the failed state of its outputs.
2012-03-18	Drop the externals directory	Eelco Dolstra	3	-6/+8
	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 directory	Eelco Dolstra	4	-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	Fix compilation on FreeBSD	Eelco Dolstra	2	-0/+2
	http://hydra.nixos.org/build/2213576 Not sure why compilation doesn't fail on other platforms...
2012-03-05	Set the close-on-exec flag on file descriptors	Eelco Dolstra	5	-3/+20

2012-03-05	Don't leak a file descriptor in commonChildInit()	Eelco Dolstra	1	-0/+1

2012-03-05	nix-worker: put the pid of the caller in argv[1]	Eelco Dolstra	3	-2/+25
	This is useful for debugging.
2012-03-05	Restore progress indication during nix-copy-closure	Eelco Dolstra	1	-0/+2

2012-03-01	Remove dependency on sqlite3_table_column_metadata	Eelco Dolstra	1	-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 variable	Eelco Dolstra	1	-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 builds	Eelco Dolstra	1	-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 bit	Eelco Dolstra	6	-4/+122
	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 Dolstra	1	-2/+5
	Because of an outdated check for a timestamp of 0, we were calling utime() even when it wasn't necessary.
2012-02-15	Don't use deletePath() to delete a single file	Eelco Dolstra	1	-1/+1

2012-02-09	Fix error message	Eelco Dolstra	1	-3/+4
	This fixes the error message error: file `' was not found in the Nix search path (add it using $NIX_PATH or -I)
2012-02-09	Use data() instead of c_str() where appropriate	Eelco Dolstra	9	-18/+18

2012-02-04	* Inline some functions and get rid of the indirection through	Eelco Dolstra	7	-116/+94
	EvalState::eval(). This gives a 12% speedup on ‘nix-instantiate /etc/nixos/nixos/ -A system --readonly-mode’ (from 1.01s to 0.89s).
2012-02-04	* Print elapsed evaluation time.	Eelco Dolstra	1	-1/+9

2012-01-26	* Fix importing a derivation. This gave a segfault.	Eelco Dolstra	1	-8/+23

2012-01-19	* Allow comparisons between derivations by comparing the outPath	Eelco Dolstra	1	-2/+14
	attributes.
2012-01-19	* Add some debug output to print the derivation name once it's known.	Eelco Dolstra	1	-1/+4
	This makes it easier to pinpoint the source of a crash.
2012-01-17	* Added a command ‘nix-store --print-env $drvpath’ that prints out the	Eelco Dolstra	1	-0/+35
	environment of the given derivation in a format that can be sourced by the shell, e.g. $ eval "$(nix-store --print-env $(nix-instantiate /etc/nixos/nixpkgs -A pkg))" $ NIX_BUILD_TOP=/tmp $ source $stdenv/setup This is especially useful to reproduce the environment used to build a package outside of its builder for development purposes. TODO: add a nix-build option to do the above and fetch the dependencies of the derivation as well.
2012-01-07	* Don't create thunks for simple constants (integers, strings, paths)	Eelco Dolstra	5	-133/+193
	and allocate them only once. * Move Value and related functions into value.hh.
2012-01-04	* Remove dead code.	Eelco Dolstra	2	-4/+0

2012-01-04	* Don't use dynamic_cast, it's very slow. "nix-instantiate	Eelco Dolstra	3	-24/+23
	/etc/nixos/nixos -A system" spent about 10% of its time in dynamic_cast.
2012-01-03	* Drop the inefficient "Path" suffix in output attribute names.	Eelco Dolstra	1	-3/+1

2012-01-03	* Move the implementation of the ‘derivation’ primop into a separate	Eelco Dolstra	2	-25/+3
	file.
2012-01-03	* Sync with the trunk.	Eelco Dolstra	1	-1/+1

2012-01-03	* Refactoring: Get rid of a few subdirectories in corepkgs/, and some	Eelco Dolstra	1	-1/+1
	other simplifications. * Use <nix/...> to locate the corepkgs. This allows them to be overriden through $NIX_PATH. * Use bash's pipefail option in the NAR builder so that we don't need to create a temporary file.
2011-12-30	* Support multiple outputs in nix-store (specifically the ‘--query’	Eelco Dolstra	1	-43/+63
	and ‘--realise’ actions).
2011-12-30	* Oops.	Eelco Dolstra	1	-1/+1

2011-12-30	* Move topoSortPaths() out of gc.cc.	Eelco Dolstra	2	-36/+36
