2009-05-11	* Disallow equality tests between attribute sets. This was always	Eelco Dolstra	1	-6/+42
	broken, but now the evaluator checks for it to prevent Nix expressions from relying on undefined behaviour. Equality tests are implemented using a shallow pointer equality test between ATerms. However, because attribute sets are lazy and contain position information, this can give false positives. For instance, previously let y = {x = 1;}; in y == y evaluated to true, while the equivalent expression {x = 1;} == {x = 1;} evaluated to false. So disallow these tests for now. (Eventually we may want to implement deep equality tests for attribute sets, like lib.eqStrict.) * Idem: disallow comparisons between functions. * Implemented deep comparisons of lists. This had the same problem as attribute sets - the elements in the list weren't evaluated. For instance, ["xy"] == [("x" + "y")] evaluated to false. Now it works properly.

2009-05-07	* Build a PDF version of the manual in the tarball job (it's not	Eelco Dolstra	1	-1/+5
	included in the tarball though).
2009-05-07	* Don't have a bugs section in the manual. Bugs should be kept in the	Eelco Dolstra	1	-1/+1
	bug tracker.
2009-05-07	* Produce the manual in the tarball job.	Eelco Dolstra	1	-5/+6

2009-05-07	* Remove a right recursion that causes the parser to barf on very long	Eelco Dolstra	1	-6/+3
	lists. The comment about ATreverse requiring unbounded stack space was unfounded anyway.
2009-05-07	* Include the version file.	Eelco Dolstra	1	-1/+1

2009-05-07	* Typo.	Eelco Dolstra	1	-1/+1

2009-05-04	Add an ftruncate call paired with fallocate to play safe with some FSes ↵	Michael Raskin	2	-0/+9
	(namely, BtrFS fallocate sets file size to allocated size, i.e. multiple of block size)
2009-04-21	* Machines of type x86_64-linux can do i686-linux builds.	Eelco Dolstra	1	-1/+3

2009-04-21	* Use foreach in a lot of places.	Eelco Dolstra	10	-96/+59

2009-04-21	* nix-store --verify: don't bail out if a referenced path is missing.	Eelco Dolstra	1	-14/+13
	(It can't fix it though.)
2009-04-16	* Fix a few "comparison is always false/true due to limited range of	Eelco Dolstra	3	-5/+5
	data type" warnings on 64-bit platforms. The one in parser.y is likely to be a real bug.
2009-04-16	* Cleanup.	Eelco Dolstra	1	-15/+6

2009-04-15	* Don't cache transient build hook problems.	Eelco Dolstra	1	-6/+11

2009-04-14	* Remove references to __XXX primops.	Eelco Dolstra	2	-14/+4

2009-04-14	* Release notes.	Eelco Dolstra	1	-0/+60

2009-04-02	* Debian packages: use /etc, not /usr/etc.	Eelco Dolstra	1	-0/+1

2009-03-31	* Do a substitution even if --max-jobs == 0.	Eelco Dolstra	2	-18/+23

2009-03-31	* Doh!	Eelco Dolstra	1	-1/+1

2009-03-30	(no commit message)	Eelco Dolstra	1	-0/+1

2009-03-30	* Make the poll interval configurable.	Eelco Dolstra	2	-3/+3

2009-03-29	* Update the mtime on the lock file to make it easy to see when a slot	Eelco Dolstra	1	-4/+8
	was last used.
2009-03-29	* Undocument the "system" option. No sane person would use it :-)	Eelco Dolstra	1	-20/+0

2009-03-29	* With `--max-jobs 0', print a nicer error message than "Assertion	Eelco Dolstra	1	-1/+5
	`!awake.empty()' failed."
2009-03-29	* Use polling to wait for a remote build slot when using a build hook	Eelco Dolstra	2	-36/+3
	(that is, call the build hook with a certain interval until it accepts the build). * build-remote.pl was totally broken: for all system types other than the local system type, it would send all builds to the first machine of the appropriate type.
2009-03-28	* nix-copy-closure: compute the closure in one call to nix-store,	Eelco Dolstra	2	-26/+10
	which is much faster.
2009-03-28	* Scan for references and compute the SHA-256 hash of the output in	Eelco Dolstra	3	-89/+50
	one pass. This halves the amount of I/O.
2009-03-28	* Don't use the non-standard __gnu_cxx::stdio_filebuf class.	Eelco Dolstra	2	-33/+17

2009-03-28	* Simplify communication with the hook a bit (don't use file	Eelco Dolstra	6	-117/+68
	descriptors 3/4, just use stdin/stderr).
2009-03-28	* Clean up the output a bit.	Eelco Dolstra	1	-5/+5

2009-03-28	* The `fixedOutput' variable didn't get initialised when using a build	Eelco Dolstra	1	-5/+6
	hook, causing negative caching to fail randomly.
2009-03-27	* Argh, stupid timing sensitive tests...	Eelco Dolstra	1	-4/+4

2009-03-27	* Debian 5.0, Ubuntu 8.10 builds.	Eelco Dolstra	1	-4/+8

2009-03-27	* Create /nix/store if it doesn't exist.	Eelco Dolstra	1	-0/+2

2009-03-26	* A job for creating a fully statically linked binary tarball.	Eelco Dolstra	1	-1/+22

2009-03-26	* Support doing a fully static build. Statically linked Nix binaries	Eelco Dolstra	1	-11/+24
	will be useful as a fallback on platforms for which there are no RPMs/Debs available.
2009-03-26	* Don't use ULLONG_MAX in maxFreed - use 0 to mean "no limit".	Eelco Dolstra	4	-10/+8
	18446744073709551615ULL breaks on GCC 3.3.6 (`integer constant is too large for "long" type').
2009-03-25	* Negative caching, i.e. caching of build failures. Disabled by	Eelco Dolstra	7	-7/+140
	default. This is mostly useful for Hydra.
2009-03-25	* Removed the locking.sh test; it's redundant because of the extended	Eelco Dolstra	5	-45/+11
	parallel.sh test. Also, don't call multiple nix-builds in parallel, since they can race creating .nix-build-tmp-derivation.
2009-03-25	* Use bash in the tests.	Eelco Dolstra	2	-1/+2

2009-03-24	* Doh.	Eelco Dolstra	1	-1/+1

2009-03-24	(no commit message)	Eelco Dolstra	1	-1/+1

2009-03-23	* Make this test a bit more robust. It's still timing dependent	Eelco Dolstra	3	-10/+14
	though.
2009-03-23	* Shut up a GCC warning.	Eelco Dolstra	1	-2/+2

2009-03-23	* No longer block while waiting for a lock on a store path. Instead	Eelco Dolstra	5	-28/+85
	poll for it (i.e. if we can't acquire the lock, then let the main select() loop wait for at most a few seconds and then try again). This improves parallelism: if two nix-store processes are both trying to build a path at the same time, the second one shouldn't block; it should first see if it can build other goals. Also, it prevents the deadlocks that have been occuring in Hydra lately, where a process waits for a lock held by another process that's waiting for a lock held by the first. The downside is that polling isn't really elegant, but POSIX doesn't provide a way to wait for locks in a select() loop. The only solution would be to spawn a thread for each lock to do a blocking fcntl() and then signal the main thread, but that would require pthreads.
2009-03-22	* Refactoring.	Eelco Dolstra	1	-136/+85

2009-03-22	* Test case (currently fails): multiple Nix builds shouldn't block	Eelco Dolstra	1	-2/+34
	waiting on the same lock when there are other builds that can be done.
2009-03-22	* Better error message when nix-store --import is applied to garbage	Eelco Dolstra	1	-1/+1
	(previously it would likely say "implementation cannot deal with > 32-bit integers").
2009-03-22	* NAR archives: handle files larger than 2^32 bytes. Previously it	Eelco Dolstra	7	-17/+48
	would just silently store only (fileSize % 2^32) bytes. * Use posix_fallocate if available when unpacking archives. * Provide a better error message when trying to unpack something that isn't a NAR archive.
