2010-08-04	* Remove "auto" and "guess" as synonyms for 0 in the handling of	Eelco Dolstra
	build-cores and --cores. They're superfluous and just complicate the parsing.
2010-06-23	Added support for passing an (impure) NIX_BUILD_CORES variable to build ↵	Peter Simons
	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.
2009-03-29	* Undocument the "system" option. No sane person would use it :-)	Eelco Dolstra

2009-03-25	* Negative caching, i.e. caching of build failures. Disabled by	Eelco Dolstra
	default. This is mostly useful for Hydra.
2008-11-19	* Removed obsolete option.	Eelco Dolstra

2008-11-11	* Add /dev/pts to the default nix.conf.	Eelco Dolstra

2007-10-29	(no commit message)	Eelco Dolstra

2007-10-27	* Delete the chroot directory automatically.	Eelco Dolstra
	* Removed some debug messages.
2006-12-08	* Kill a build if it has gone for more than a certain number of	Eelco Dolstra
	seconds without producing output on stdout or stderr (NIX-65). This timeout can be specified using the `--max-silent-time' option or the `build-max-silent-time' configuration setting. The default is infinity (0). * Fix a tricky race condition: if we kill the build user before the child has done its setuid() to the build user uid, then it won't be killed, and we'll potentially lock up in pid.wait(). So also send a conventional kill to the child.
2006-12-06	* Urgh.	Eelco Dolstra

2006-12-06	* Oops.	Eelco Dolstra

2006-12-06	* Get rid of `build-users'. We'll just take all the members of	Eelco Dolstra
	`build-users-group'. This makes configuration easier: you can just add users in /etc/group.
2006-12-03	* Removed `build-allow-root'.	Eelco Dolstra
	* Added `build-users-group', the group under which builds are to be performed. * Check that /nix/store has 1775 permission and is owner by the build-users-group.
2006-08-10	* New configuration setting `build-max-jobs' which sets the default	Eelco Dolstra
	for the `-j' flag (i.e., the maximum number of jobs to execute in parallel). Useful on multi-processor machines.
2006-07-06	* Allow the canonical system name to be specified at runtime in the	Eelco Dolstra
	Nix config file.
2006-02-16	* Allow the size of the GC reserved file to be specified in nix.conf	Eelco Dolstra
	through the new `gc-reserved-space' option.
2005-09-22	* Parse multi-valued options.	Eelco Dolstra

2005-09-21	* This doesn't parse for now.	Eelco Dolstra

2005-09-21	* Configuration options for trusted local builds.	Eelco Dolstra

2005-02-14	* Global configuration option `env-keep-derivations' to store pointer	Eelco Dolstra
	to derivations in user environments. Nice for developers (since it prevents build-time-only dependencies from being GC'ed, in conjunction with `gc-keep-outputs'). Turned off by default.
2005-02-01	* Added a global configuration file (/nix/etc/nix/nix.conf). It	Eelco Dolstra
	contains options for the garbage collector right now, but other stuff can be added here later.
