Eelco Dolstra	98df735b51	* Propagate the deriver of a path through the substitute mechanism. ... * Removed some dead code (successor stuff) from nix-push. * Updated terminology in the tests (store expr -> drv path). * Check that the deriver is set properly in the tests.	2005-02-09 12:57:13 +00:00
Eelco Dolstra	c3981d81f6	* Make check fixes.	2005-02-01 17:50:48 +00:00
Eelco Dolstra	32fa82a56a	* Acquire a global GC lock to prevent new temporary root files from ... being created after the garbage collector has read the temproots directory. This blocks the creation of new processes, but the garbage collector could periodically release the GC lock to allow them to run.	2005-01-31 22:23:49 +00:00
Eelco Dolstra	89c9bc11ab	* Add a test for a more subtle race: a process starting after the ... temporary root files have been read but creating outputs before the store directory has been read.	2005-01-31 22:01:55 +00:00
Eelco Dolstra	1328aa3307	* Start of concurrent garbage collection. Processes write temporary ... 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.	2005-01-31 10:27:25 +00:00
Eelco Dolstra	a7668411a1	* Add a test to check whether concurrent garbage collection (i.e., ... running the collector while builds are in progress) works correctly. The test currently fails.	2005-01-28 20:36:46 +00:00
