2004-05-11	* True parallel builds. Nix can now run as many build jobs in	Eelco Dolstra	7	-286/+658
	parallel as possible (similar to GNU Make's `-j' switch). This is useful on SMP systems, but it is especially useful for doing builds on multiple machines. The idea is that a large derivation is initiated on one master machine, which then distributes sub-derivations to any number of slave machines. This should not happen synchronously or in lock-step, so the master must be capable of dealing with multiple parallel build jobs. We now have the infrastructure to support this. TODO: substitutes are currently broken.
2004-04-14	* Be stricter in verifying store paths.	Eelco Dolstra	3	-4/+9

2004-03-22	* Some more nesting.	Eelco Dolstra	1	-4/+13

2004-03-12	* Set the NIX_STORE and NIX_BUILD_TOP environment variables in	Eelco Dolstra	3	-3/+19
	builders to point to the store and the temporary build directory, respectively. Useful for purity checking. * Also set TEMPDIR, TMPDIR, TEMP, and TEMP to NIX_BUILD_TOP to make sure that tools in the builder store temporary files in the right location.
2004-02-16	* Allow linking against an external Berkeley DB / ATerm library.	Eelco Dolstra	1	-1/+1

2004-02-14	* The environment variable NIX_ROOT can now be set to execute Nix in a	Eelco Dolstra	1	-9/+29
	chroot() environment. * A operation `--validpath' to register path validity. Useful for bootstrapping in a pure Nix environment. * Safety checks: ensure that files involved in store operations are in the store.
2004-02-13	* Regression fix: realise substitutes and detect cycles.	Eelco Dolstra	1	-1/+8

2004-01-15	* Catch SIGINT to terminate cleanly when the user tries to interrupt	Eelco Dolstra	6	-4/+27
	Nix. This is to prevent Berkeley DB from becoming wedged. Unfortunately it is not possible to throw C++ exceptions from a signal handler. In fact, you can't do much of anything except change variables of type `volatile sig_atomic_t'. So we set an interrupt flag in the signal handler and check it at various strategic locations in the code (by calling checkInterrupt()). Since this is unlikely to cover all cases (e.g., (semi-)infinite loops), sometimes SIGTERM may now be required to kill Nix.
2004-01-13	* Option `-B' to always show the output of builders, regardless of	Eelco Dolstra	3	-1/+7
	verbosity level.
2004-01-13	* Periodically checkpoint the log.	Eelco Dolstra	1	-1/+3

2004-01-13	* Tricky: make sure that the accessor count is not reset to 0 if	Eelco Dolstra	1	-1/+5
	recovery fails.
2004-01-13	* Print error messages, not debug messages.	Eelco Dolstra	1	-5/+9

2004-01-12	* Changed the extension for store expressions from ".nix" to ".store"	Eelco Dolstra	1	-1/+1
	(following the Usenix paper).
2004-01-07	* Upgraded to Berkeley DB 4.2.52. The main advantage of 4.2 is that	Eelco Dolstra	1	-1/+1
	it automatically removes log files when they are no longer needed. * IMPORTANT * If you have an existing Nix installation, you must checkpoint the Nix database to prevent recent transactions from being undone. Do the following: - optional: make a backup of $prefix/var/nix/db. - run `db_checkpoint' from Berkeley DB 4.1: $ db_checkpoint -h $prefix/var/nix/db -1 - optional (?): run `db_recover' from Berkeley DB 4.1: $ db_recover -h $prefix/var/nix/db - remove $prefix/var/nix/db/log* and $prefix/var/nix/db/__db*
2004-01-05	* Implemented Eelco V.'s `nix-env -I' command to specify the default	Eelco Dolstra	1	-6/+2
	path of the Nix expression to be used with the import, upgrade, and query commands. For instance, $ nix-env -I ~/nixpkgs/pkgs/system/i686-linux.nix $ nix-env --query --available [aka -qa] sylpheed-0.9.7 bison-1.875 pango-1.2.5 subversion-0.35.1 ... $ nix-env -i sylpheed $ nix-env -u subversion There can be only one default at a time. * If the path to a Nix expression is a symlink, follow the symlink prior to resolving relative path references in the expression.
2003-12-22	* GCC 2.95 compatibility.	Eelco Dolstra	2	-0/+2

2003-12-21	* Bug fix: parallel builds of the same derivation failed due to lock file ↵	Eelco Dolstra	1	-3/+5
	removal.
2003-12-05	* Allow successors that don't exist but have a substitute.	Eelco Dolstra	1	-34/+73
	* Integrity: check in successor / substitute registration whether the target path exists or has a substitute.
2003-12-01	* Use a system name that does not include the OS manufacturer (i.e.,	Eelco Dolstra	1	-1/+1
	"i686-linux" instead of "i686-suse-linux").
2003-11-25	* More `make dist' fixes.	Eelco Dolstra	1	-4/+4

2003-11-25	* `make dist' fix.	Eelco Dolstra	1	-8/+1

2003-11-24	* Bug fix in path invalidation.	Eelco Dolstra	1	-23/+41
	* More consistency checks.
2003-11-22	* Maintain integrity of the substitute and successor mappings when	Eelco Dolstra	3	-40/+55
	deleting a path in the store. * Allow absolute paths in Nix expressions. * Get nix-prefetch-url to work again. * Various other fixes.
2003-11-22	* Fix the garbage collector.	Eelco Dolstra	1	-8/+1

2003-11-21	* Remove lock files after building.	Eelco Dolstra	3	-1/+20

2003-11-19	* nix-env: a tool to manage user environments.	Eelco Dolstra	4	-10/+10
	* Replace all directory reading code by a generic readDirectory() function.
2003-11-18	* "Nix expression" -> "store expression".	Eelco Dolstra	5	-79/+64
	* More refactoring.
2003-11-18	* libnix -> libstore.	Eelco Dolstra	20	-0/+2285
