2010-10-24	* Don't create thunks for variable lookups (if possible). This	Eelco Dolstra	3	-23/+60
	significantly reduces the number of values allocated (e.g. from 8.7m to 4.9m for the Bittorrent test).
2010-10-24	* Store attribute sets as a vector instead of a map (i.e. a red-black	Eelco Dolstra	7	-90/+129
	tree). This saves a lot of memory. The vector should be sorted so that names can be looked up using binary search, but this is not the case yet. (Surprisingly, looking up attributes using linear search doesn't have a big impact on performance.) Memory consumption for $ nix-instantiate /etc/nixos/nixos/tests -A bittorrent.test --readonly-mode on x86_64-linux with GC enabled is now 185 MiB (compared to 946 MiB on the trunk).
2010-10-23	* Fix compiling without Boehm.	Eelco Dolstra	1	-10/+8
	* Fix the stats.
2010-10-23	* Regression test for listToAttr's behaviour if an attribute name	Eelco Dolstra	2	-2/+3
	occurs multiple times.
2010-10-23	* Optimise string constants by putting them in the symbol table.	Eelco Dolstra	4	-39/+55

2010-10-23	* Make Value smaller by not storing redundant PrimOp info.	Eelco Dolstra	2	-25/+44
	* Clear pointers in Values after overwriting them to make sure that no objects are kept alive unnecessarily.
2010-10-23	* Remove allocValues().	Eelco Dolstra	4	-36/+14

2010-10-22	* In environments, store pointers to values rather than values. This	Eelco Dolstra	2	-35/+25
	improves GC effectiveness a bit more (because a live value doesn't keep other values in the environment plus the parent environments alive), and removes the need for copy nodes.
2010-10-22	* Regression test for __overrides.	Eelco Dolstra	2	-0/+10

2010-10-22	* Store Value nodes outside of attribute sets. I.e., Attr now stores	Eelco Dolstra	15	-130/+150
	a pointer to a Value, rather than the Value directly. This improves the effectiveness of garbage collection a lot: if the Value is stored inside the set directly, then any live pointer to the Value causes all other attributes in the set to be live as well.
2010-10-22	* Make building against the Boehm GC a configure option.	Eelco Dolstra	6	-14/+42

2010-10-20	* Keep some more stats.	Eelco Dolstra	2	-0/+12

2010-10-20	* Use the Boehm garbage collector to reclaim unused memory in the Nix	Eelco Dolstra	5	-15/+29
	expression evaluator.
2010-10-20	* Evaluator garbage collection branch.	Eelco Dolstra	0	-0/+0

2010-10-06	nix manual: fix 'install' -> 'uninstall' in garbage collection section of ↵	Rob Vermaas	1	-1/+1
	introduction
2010-10-04	* In the referrers test, lower the nesting depth from 2500 to 1000 to	Eelco Dolstra	1	-1/+1
	prevent hitting a stack overflow bug in the garbage collector.
2010-10-04	* Make sure that config.h is included before the system headers,	Eelco Dolstra	12	-29/+29
	because it defines _FILE_OFFSET_BITS. Without this, on OpenSolaris the system headers define it to be 32, and then the 32-bit stat() ends up being called with a 64-bit "struct stat", or vice versa. This also ensures that we get 64-bit file sizes everywhere. * Remove the redundant call to stat() in parseExprFromFile(). The file cannot be a symlink because that's the exit condition of the loop before.
2010-10-04	* If std::tr1::unordered_set is unavailable, use std::set.	Eelco Dolstra	2	-0/+16

2010-10-04	* "type -P" isn't portable.	Eelco Dolstra	1	-1/+1

2010-10-04	* In printMsg(), ignore failing writes to stderr if we're in an	Eelco Dolstra	1	-1/+10
	exception handler, otherwise throw an exception. We need to ignore write errors in exception handlers to ensure that cleanup code runs to completion if the other side of stderr has been closed unexpectedly.
2010-10-04	* Hack needed for GCC 4.3.2 on OpenSolaris.	Eelco Dolstra	1	-1/+1

2010-09-14	* Doh. Remove debug message.	Eelco Dolstra	1	-1/+0

2010-08-27	* Oops - "null" was displayed as "true".	Eelco Dolstra	1	-1/+1

2010-08-24	* nix-build: pass --cores.	Eelco Dolstra	1	-1/+1

2010-08-17	* Bump the version number.	Eelco Dolstra	1	-1/+1

2010-08-17	* rpmBuild already includes the disk image in the output name.	Eelco Dolstra	1	-1/+1

2010-08-17	* Update date.	Eelco Dolstra	1	-1/+2

2010-08-17	* Document --cores in the manual.	Eelco Dolstra	5	-5/+46

2010-08-16	* Typo.	Eelco Dolstra	1	-1/+1

2010-08-16	* Remove the "tarball" jobset argument.	Eelco Dolstra	1	-53/+20

2010-08-16	* Nix 0.16 release notes.	Eelco Dolstra	1	-0/+53

2010-08-12	* Urgh, this was supposed to go in the trunk...	Eelco Dolstra	1	-3/+0

2010-08-12	* Make --cores work when building through the Nix daemon.	Eelco Dolstra	3	-1/+7

2010-08-04	* Remove "auto" and "guess" as synonyms for 0 in the handling of	Eelco Dolstra	2	-20/+8
	build-cores and --cores. They're superfluous and just complicate the parsing.
2010-08-04	* Set the default system filter to "*". This ensures that (for	Eelco Dolstra	1	-7/+13
	instance) "nix-env -i wine" works on x86_64-linux, even though Wine is built on i686-linux. In the event that there are multiple matching derivations, prefer those built for the current system.
2010-08-02	* Optimisation in the // operator: if one of the sets is empty, return	Eelco Dolstra	1	-6/+8
	the other set.
2010-08-02	* intersectAttrs: optimise for the case where the second set is larger	Eelco Dolstra	1	-7/+7
	than the first set. (That's usually the case with callPackage.)
2010-07-21	* Don't barf if the source NAR for a patch has disappeared.	Eelco Dolstra	1	-1/+6

2010-07-15	src/bsdiff-4.3/Makefile.am: include the 'compat-include' directory in ↵	Peter Simons	1	-0/+2
	distribution tarballs
2010-06-25	tests/build-hook.hook.sh: prefer more portable `...` syntax over $(...) for ↵	Peter Simons	1	-2/+2
	running sub-shells The /bin/sh interpreter on Solaris doesn't understand $(...) syntax for running sub-shells. Consequently, this test fails on Solaris. To remedy the situation, the script either needs to be run by /bin/bash -- which is non-standard --, or it needs to use the ancient but portable `...` syntax.
2010-06-24	Revert "configure.ac: make flex and bison required programs"	Peter Simons	1	-2/+2
	This reverts commit 22405. Apparently, these programs aren't necessarily required when building from a release archive.
2010-06-24	Fix build of bsdiff-4.3 on machines that don't have <err.h>, such as Solaris.	Peter Simons	3	-1/+17

2010-06-24	configure.ac: Incredibly enough, tr(1) on Solaris doesn't understand A-Z ↵	Peter Simons	1	-3/+3
	syntax for ranges.
2010-06-24	configure.ac: make flex and bison required programs	Peter Simons	1	-2/+2
	The build fails if these tools aren't available.
2010-06-24	src/libutil/util.cc: include <limit.h> to ensure that PATH_MAX is defined	Peter Simons	1	-0/+1

2010-06-24	Include <cstring> to ensure that strcpy(), strlen(), and memset() are declared.	Peter Simons	3	-0/+6
	An "using namespace std" was added locally in those functions that refer to names from <cstring>. That is not pretty, but it's a very portable solution, because strcpy() and friends will be found in both the 'std' and in the global namespace.
2010-06-23	* Ignore packages that don't have a version.	Eelco Dolstra	1	-15/+18
	* Work on a manifest instead of a channel directory.
2010-06-23	Added support for passing an (impure) NIX_BUILD_CORES variable to build ↵	Peter Simons	5	-0/+35
	expressions. This patch adds the configuration file variable "build-cores" and the command line argument "--cores". These settings specify the number of CPU cores to utilize for parallel building within a job, i.e. by passing an appropriate "-j" flag to GNU Make. The default value is 1, which means that parallel building is disabled. If the number of build cores is specified as 0 (synonymously: "guess" or "auto"), then the actual value is supposed to be auto-detected by builders at run-time, i.e by calling the nproc(1) utility from coreutils. The environment variable $NIX_BUILD_CORES is available to builders, but the contents of that variable does not influence the hash that goes into the $out store path, i.e. the number of build cores to be utilized can be changed at will without requiring any re-builds.
2010-06-22	* Pass `--fallback' to the remote build to ignore failing	Eelco Dolstra	1	-2/+2
	substituters.
2010-06-14	* In importPath() and exportPath(), lock the temporary directory to	Eelco Dolstra	1	-0/+4
	prevent it from being deleted by the garbage collector.
