2010-02-18	* Automatically abort transactions if they go out of scope without	Eelco Dolstra	1	-6/+37
	committing.
2010-02-18	* Some wrapper objects to ensure that SQLite objects are properly	Eelco Dolstra	2	-49/+109
	destroyed.
2010-02-18	* Add the deriver to the ValidPaths table. In principle we could now	Eelco Dolstra	2	-13/+21
	store all the derivers of a path efficiently. But that opens a big can of worms with respect to garbage collector semantics.
2010-02-18	* Assign an integer id to every row in the ValidPaths table in order	Eelco Dolstra	2	-14/+25
	to make the Refs table more space-efficient. For instance, this reduces the size of the database on my laptop from 93 MiB to 18 MiB. (It was 72 MiB with the old schema on an ext3 disk with a 1 KiB block size.)
2010-02-18	* Convert the Nix database to SQLite.	Eelco Dolstra	5	-15/+148

2010-02-10	Don't rely on `PATH_MAX' on GNU.	Ludovic Courtès	1	-0/+10

2010-02-03	* Revert r19797, and use a simpler solution: just don't monitor build	Eelco Dolstra	4	-37/+21
	hooks for silence. It's unnecessary because the remote nix-store command is already monitoring the real build.
2010-02-03	* While waiting for a lock, print a sign of life every 5 minutes.	Eelco Dolstra	3	-3/+27
	This prevents remote builders from being killed by the `max-silent-time' inactivity monitor while they are waiting for a long garbage collection to finish. This happens fairly often in the Hydra build farm.
2010-02-02	* Remove most Cygwin-specific code. Cygwin 1.7 implements advisory	Eelco Dolstra	4	-112/+5
	POSIX locks, and simulates Unix-style file deletion semantics sufficiently. Note that this means that Nix won't work on Cygwin 1.5 anymore.
2010-02-02	* If fdatasync() isn't available, use fsync().	Eelco Dolstra	1	-0/+4

2010-01-29	* Added an option "fsync-metadata" to fsync() changes to	Eelco Dolstra	5	-27/+26
	/nix/var/nix/db. * Removed the function writeStringToFile since it does (almost) the same thing as writeFile.
2010-01-29	* Don't consider a store path valid if its info file exists but is	Eelco Dolstra	1	-4/+36
	zero bytes long. That makes Nix more robust in case of crashes (especially on ext4).
2010-01-25	* Made `nix-store -qR --include-outputs' much faster if there are	Eelco Dolstra	3	-41/+13
	multiple paths specified on the command line (from O(n * m) to O(n + m), where n is the number of arguments and m is the size of the closure).
2010-01-25	* Make the garbage collector do the right thing when `gc-keep-outputs'	Eelco Dolstra	4	-18/+90
	is enabled by not depending on the deriver.
2010-01-12	* On startup, set the default SIGCHLD handler. This is so that Nix	Eelco Dolstra	1	-5/+11
	works correctly in weird environments where the SIGCHLD handler is set to "ignore".
2009-12-17	* Include config.h before the C library headers, because it defines	Eelco Dolstra	3	-4/+6
	_FILE_OFFSET_BITS=64. Without it, functions like stat() fail on large file sizes. This happened with a Nix store on squashfs: $ nix-store --dump /tmp/mnt/46wzqnk4cbdwh1dclhrpqnnz1icak6n7-local-net-cmds > /dev/null error: getting attributes of path `/tmp/mnt/46wzqnk4cbdwh1dclhrpqnnz1icak6n7-local-net-cmds': Value too large for defined data type $ stat /tmp/mnt/46wzqnk4cbdwh1dclhrpqnnz1icak6n7-local-net-cmds File: `/tmp/mnt/46wzqnk4cbdwh1dclhrpqnnz1icak6n7-local-net-cmds' Size: 0 Blocks: 36028797018963968 IO Block: 1024 regular empty file (This is a bug in squashfs or mksquashfs, but it shouldn't cause Nix to fail.)
2009-12-16	* Build correctly against newer ATerm releases. Fixes "error: 'union'	Eelco Dolstra	2	-3/+2
	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	* Grrr.	Eelco Dolstra	1	-1/+1

2009-11-24	* GCC 4.4 is stricter about the EOF macro	Eelco Dolstra	1	-0/+2
	(http://hydra.nixos.org/build/156340).
2009-11-24	* Templatise getIntArg / string2Int.	Eelco Dolstra	5	-40/+25

2009-11-24	* In the garbage collector, don't count files with a link count > 1 in	Eelco Dolstra	1	-2/+4
	the "bytes/blocks freed" statistics.
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	* A command `nix-store --query --roots <paths>' to find the garbage	Eelco Dolstra	2	-31/+31
	collector roots that point (directly or indirectly) to the given paths.
2009-11-23	* `nix-store --gc --print-roots': also print the path of the actual	Eelco Dolstra	3	-17/+16
	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	6	-158/+11
	(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	11	-702/+25

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

2009-10-22	* builtins.trace: in the common case that the value is a string, then	Eelco Dolstra	1	-1/+6
	show the string, not the ATerm, so we get `trace: bla' instead of `trace: Str("bla",[])'.
2009-10-21	* Added a primop unsafeDiscardOutputDependency needed by Disnix to	Eelco Dolstra	1	-3/+34
	pass derivation paths to a builder without actually building them.
2009-10-13	* Give a useful error message when an evaluation error occurs while	Eelco Dolstra	1	-41/+48
	trying to upgrade a package.
2009-10-08	Added optional parameter which adds -lnsl -lsocket to make the Nix package ↵	Sander van der Burg	6	-6/+6
	manager work on OpenSolaris
2009-09-30	* Support platforms that don't have O_ASYNC (e.g. OpenSolaris	Eelco Dolstra	1	-3/+17
	apparently).
2009-09-30	* OpenSolaris compatibility.	Eelco Dolstra	1	-1/+6

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	* tryEval shouldn't catch all exceptions of type Error, since not all	Eelco Dolstra	1	-2/+2
	of them leave the evaluator in a continuable state. Also, it should be less chatty.
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

2009-09-15	* Two primops: builtins.intersectAttrs and builtins.functionArgs.	Eelco Dolstra	1	-0/+66
	intersectAttrs returns the (right-biased) intersection between two attribute sets, e.g. every attribute from the second set that also exists in the first. functionArgs returns the set of attributes expected by a function. The main goal of these is to allow the elimination of most of all-packages.nix. Most package instantiations in all-packages.nix have this form: foo = import ./foo.nix { inherit a b c; }; With intersectAttrs and functionArgs, this can be written as: foo = callPackage (import ./foo.nix) { }; where callPackage = f: args: f ((builtins.intersectAttrs (builtins.functionArgs f) pkgs) // args); I.e., foo.nix is called with all attributes from "pkgs" that it actually needs (e.g., pkgs.a, pkgs.b and pkgs.c). (callPackage can do any other generic package-level stuff we might want, such as applying makeOverridable.) Of course, the automatically supplied arguments can be overriden if needed, e.g. foo = callPackage (import ./foo.nix) { c = c_version_2; }; but for the vast majority of packages, this won't be needed. The advantages are to reduce the amount of typing needed to add a dependency (from three sites to two), and to reduce the number of trivial commits to all-packages.nix. For the former, there have been two previous attempts: - Use "args: with args;" in the package's function definition. This however obscures the actual expected arguments of a function, which is very bad. - Use "{ arg1, arg2, ... }:" in the package's function definition (i.e. use the ellipis "..." to allow arbitrary additional arguments), and then call the function with all of "pkgs" as an argument. But this inhibits error detection if you call it with an misspelled (or obsolete) argument.
2009-08-25	Adding tryEval builtin. It allows to catch presence of errors in an expression.	Michael Raskin	1	-0/+18

2009-07-02	* Replace newlines in table output with spaces.	Eelco Dolstra	1	-6/+7

2009-06-30	* Support integers and lists of strings in meta fields. This is	Eelco Dolstra	3	-41/+106
	useful for fields like meta.maintainers, meta.priority (which can be a proper integer now) and even meta.license (if there are multiple licenses).
2009-06-30	* Don't show trace information by default (`--show-trace' to enable).	Eelco Dolstra	4	-3/+12
	NixOS evaluation errors in particular look intimidating and generally aren't very useful. Ideally the builtins.throw messages should be self-contained.
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.
2009-05-15	* Change the scoping of "inherit (e) ..." in recs so that the	Eelco Dolstra	1	-2/+3
	attributes of the rec are in scope of `e'. This is useful in expressions such as rec { lib = import ./lib; inherit (lib) concatStrings; } It does change the semantics of expressions such as let x = {y = 1;}; in rec { x = {y = 2;}; inherit (x) y; }.y This now returns 2 instead of 1. However, no code in Nixpkgs or NixOS seems to rely on the old behaviour.
