2005-01-31	* Start of concurrent garbage collection. Processes write temporary	Eelco Dolstra	1	-1/+7
	roots to a per-process temporary file in /nix/var/nix/temproots while holding a write lock on that file. The garbage collector acquires read locks on all those files, thus blocking further progress in other Nix processes, and reads the sets of temporary roots.
2005-01-27	* Fix and simplify the garbage collector (it's still not concurrent,	Eelco Dolstra	1	-2/+2
	though). In particular it's now much easier to register a GC root. Just place a symlink to whatever store path it is that you want to keep in /nix/var/nix/gcroots.
2005-01-25	* Maintain the references/referers relation also for derivations.	Eelco Dolstra	1	-3/+2
	This simplifies garbage collection and `nix-store --query --requisites' since we no longer need to treat derivations specially. * Better maintaining of the invariants, e.g., setReferences() can only be called on a valid/substitutable path.
2005-01-25	* Simplification: registerSubstitutes -> registerSubstitute. We no	Eelco Dolstra	1	-1/+0
	longer need the former since there we no longer have the substitutes-rev table (which triggered a O(n^2) cost in updating them).
2005-01-25	* Really fix the substitute mechanism, i.e., ensure the closure	Eelco Dolstra	1	-7/+32
	invariant by registering references through the manifest. * Added a test for nix-pull.
2005-01-25	* Fix the `--fallback' switch.	Eelco Dolstra	1	-0/+6
	* Fix the substitutes tests.
2005-01-25	* Fix the build hook mechanism; pass the pointer graph to the hook.	Eelco Dolstra	1	-2/+24

2005-01-25	* In nix-store: change `--build' back to `--realise'. Also brought	Eelco Dolstra	1	-37/+57
	back the query flag `--force-realise'. * Fixed some of the tests.
2005-01-20	* Terminology fixes.	Eelco Dolstra	1	-9/+9

2005-01-20	* Another change to low-level derivations. The last one this year, I	Eelco Dolstra	1	-11/+17
	promise :-) This allows derivations to specify on what output paths of input derivations they are dependent. This helps to prevent unnecessary downloads. For instance, a build might be dependent on the `devel' and `lib' outputs of some library component, but not the `docs' output.
2005-01-19	* Renamed `normalise.cc' -> `build.cc', `storeexprs.cc' ->	Eelco Dolstra	1	-0/+1758
	`derivations.cc', etc. * Store the SHA-256 content hash of store paths in the database after they have been built/added. This is so that we can check whether the store has been messed with (a la `rpm --verify'). * When registering path validity, verify that the closure property holds.
