2009-12-16	* Build correctly against newer ATerm releases. Fixes "error: 'union'	Eelco Dolstra	1	-1/+1
	tag used in naming 'struct _ATerm'".
2009-12-09	* Give a better error message when trying to build something and	Eelco Dolstra	1	-0/+6
	readOnlyMode is set.
2009-11-24	* Randomise the order in which we delete entries to make the collector	Eelco Dolstra	1	-2/+10
	less biased towards deleting paths that come alphabetically first (e.g. /nix/store/000...). This matters when using --max-freed etc.
2009-11-23	(no commit message)	Eelco Dolstra	1	-0/+5

2009-11-23	* `nix-store --gc --print-roots': also print the path of the actual	Eelco Dolstra	2	-10/+0
	root symlink, not just its target. E.g.: /nix/var/nix/profiles/system-99-link -> /nix/store/76kwf88657nq7wgk1hx3l1z5q91zb9wd-system
2009-11-23	* Made the garbage collector a lot faster. It no longer computes the	Eelco Dolstra	2	-166/+168
	complete set of live and dead paths before starting the actual deletion, but determines liveness on demand. I.e. for any path in the store, it first tries to delete all the referrers, and then the path itself. This means that the collector can start deleting paths almost immediately.
2009-11-20	* Remove the --use-atime / --max-atime garbage collector flags. Many	Eelco Dolstra	4	-151/+8
	(Linux) machines no longer maintain the atime because it's too expensive, and on the machines where --use-atime is useful (like the buildfarm), reading the atimes on the entire Nix store takes way too much time to make it practical.
2009-11-06	* Remove support for old (before Nix 0.12pre12020) databases.	Eelco Dolstra	5	-692/+15

2009-10-22	* When building in a chroot, make a copy of a file if hard-linking	Eelco Dolstra	1	-2/+13
	fails. This is likely to happen after a `nix-store --optimise', because some files may have 32000 links (NIX-111).
2009-10-22	* Remove a prototype for a function that no longer exists.	Eelco Dolstra	1	-3/+0

2009-10-08	Added optional parameter which adds -lnsl -lsocket to make the Nix package ↵	Sander van der Burg	1	-1/+1
	manager work on OpenSolaris
2009-09-24	* And some more.	Eelco Dolstra	2	-0/+2

2009-09-24	* Fix a build failure on Fedora 11. rename() needs <stdio.h>.	Eelco Dolstra	1	-0/+1

2009-09-23	* Darwin hack.	Eelco Dolstra	1	-0/+7

2009-09-23	* Create some state directories automatically as a convenience.	Eelco Dolstra	2	-6/+17

2009-09-23	* include wait.h for WEXITSTATUS	Rob Vermaas	1	-0/+1

2009-06-13	* Canonicalise timestamps in the Nix store to 1 (1970-01-01 00:00:01	Eelco Dolstra	2	-3/+3
	UTC) rather than 0 (00:00:00). 1 is a better choice because some programs use 0 as a special value. For instance, the Template Toolkit uses a timestamp of 0 to denote the non-existence of a file, so it barfs on files in the Nix store (see template-toolkit-nix-store.patch in Nixpkgs). Similarly, Maya 2008 fails to load script directories with a timestamp of 0 and can't be patched because it's closed source. This will also shut up those "implausibly old time stamp" GNU tar warnings.
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	1	-1/+1
	data type" warnings on 64-bit platforms. The one in parser.y is likely to be a real bug.
2009-04-15	* Don't cache transient build hook problems.	Eelco Dolstra	1	-6/+11

2009-03-31	* Do a substitution even if --max-jobs == 0.	Eelco Dolstra	1	-17/+22

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	1	-2/+2

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	1	-31/+1
	(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	* 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	1	-70/+16
	descriptors 3/4, just use stdin/stderr).
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	* Create /nix/store if it doesn't exist.	Eelco Dolstra	1	-0/+2

2009-03-26	* Don't use ULLONG_MAX in maxFreed - use 0 to mean "no limit".	Eelco Dolstra	3	-9/+4
	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	3	-6/+79
	default. This is mostly useful for Hydra.
2009-03-24	* Doh.	Eelco Dolstra	1	-1/+1

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

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	* NAR archives: handle files larger than 2^32 bytes. Previously it	Eelco Dolstra	1	-1/+1
	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.
2009-03-18	* Unify exportReferencesGraph and exportBuildReferencesGraph, and make	Eelco Dolstra	1	-48/+18
	sure that it works as expected when you pass it a derivation. That is, we have to make sure that all build-time dependencies are built, and that they are all in the input closure (otherwise remote builds might fail, for example). This is ensured at instantiation time by adding all derivations and their sources to inputDrvs and inputSrcs.
2009-03-18	* Acquire the locks on the output paths before trying to run the build	Eelco Dolstra	1	-145/+71
	hook. This fixes a problem with log files being partially or completely filled with 0's because another nix-store process truncates the log file. It should also be more efficient.
2009-03-17	* Cleanup.	Eelco Dolstra	1	-22/+9

2009-02-27	* Allow options from the Nix config file to be overriden from the	Eelco Dolstra	2	-0/+14
	command line (e.g. "--option build-use-chroot true").
2009-02-16	* Release output locks as soon as possible, not when the destructor of	Eelco Dolstra	3	-0/+14
	the DerivationGoal runs. Otherwise, if a goal is a top-level goal, then the lock won't be released until nix-store finishes. With --keep-going and lots of top-level goals, it's possible to run out of file descriptors (this happened sometimes in the build farm for Nixpkgs). Also, for failed derivation, it won't be possible to build it again until the lock is released. * Idem for locks on build users: these weren't released in a timely manner for failed top-level derivation goals. So if there were more than (say) 10 such failed builds, you would get an error about having run out of build users.
2009-02-02	* Build hooks: use nix-store --import. This prevents a redundant	Eelco Dolstra	2	-9/+27
	scan for runtime dependencies (i.e. the local machine shouldn't do a scan that the remote machine has already done). Also pipe directly into `nix-store --import': don't use a temporary file.
2009-01-27	* Make it compile on Debian 4.0 (which doesn't define PER_LINUX32_3GB	Eelco Dolstra	1	-1/+1
	in sys/personality.h).
2009-01-13	* When using a build hook, distinguish between transient failures	Eelco Dolstra	1	-4/+20
	(e.g. an SSH connection problem) and permanent failures (i.e. the builder failed). This matters to Hydra (it wants to know whether it makes sense to retry a build).
2009-01-12	* Support i686-linux builds directly on x86_64-linux Nix	Eelco Dolstra	1	-1/+18
	installations. This is implemented using the personality() syscall, which causes uname to return "i686" in child processes.
2008-12-16	* nix-store --verify: repair bad hash fields in the metadata file.	Eelco Dolstra	2	-5/+16

2008-12-16	* Pass --use-atime / --max-atime to the daemon.	Eelco Dolstra	2	-1/+5
