2005-12-25	* More GCC 2.95 compatibility.	Eelco Dolstra	1	-1/+1

2005-12-25	* Hack around a GCC 2.95 bug.	Eelco Dolstra	1	-2/+2

2005-12-24	* GCC 2.95 compatibility.	Eelco Dolstra	1	-1/+1

2005-12-23	* Added a flag `--ignore-liveness' to `nix-store --delete'. It	Eelco Dolstra	2	-3/+4
	deletes a path even if it is reachable from a root. However, it won't delete a path that still has referrers (since that would violate store invariants). Don't try this at home. It's a useful hack for recovering from certain situations in a somewhat clean way (e.g., holes in closures due to disk corruption).
2005-12-23	* Revived the old "nix-store --delete" operation that deletes the	Eelco Dolstra	2	-10/+22
	specified paths from the Nix store. However, this operation is safe: it refuses to delete anything that the garbage collector wouldn't delete.
2005-12-15	* `nix-store --gc' prints out the number of bytes freed on stdout	Eelco Dolstra	4	-6/+12
	(even when it is interrupted by a signal).
2005-12-15	* Split the database upgrade into multiple transactions to prevent	Eelco Dolstra	1	-2/+11
	Berkeley DB from running out of locks.
2005-12-13	* Change `referer' to `referrer' throughout. In particular, the	Eelco Dolstra	5	-39/+40
	nix-store query options `--referer' and `--referer-closure' have been changed to `--referrer' and `--referrer-closure' (but the old ones are still accepted for compatibility).
2005-12-12	* Automatically delete the old referers table.	Eelco Dolstra	3	-5/+31

2005-12-12	* Fix NIX-23: quadratic complexity in maintaining the referers	Eelco Dolstra	4	-40/+107
	mapping. The referer table is replaced by a referrer table (note spelling fix) that stores each referrer separately. That is, instead of having referer[P] = {Q_1, Q_2, Q_3, ...} we store referer[(P, Q_1)] = "" referer[(P, Q_2)] = "" referer[(P, Q_3)] = "" ... To find the referrers of P, we enumerate over the keys with a value lexicographically greater than P. This requires the referrer table to be stored as a B-Tree rather than a hash table. (The tuples (P, Q) are stored as P + null-byte + Q.) Old Nix databases are upgraded automatically to the new schema.
2005-12-09	* Use Berkeley DB 4.4's process registry feature to recover from	Eelco Dolstra	2	-102/+56
	crashed Nix instances, and toss out our own recovery code.
2005-12-06	* Require Berkeley DB 4.4.	Eelco Dolstra	1	-1/+3
	* Checkpoint after an upgrade.
2005-11-16	* Did something useful while waiting at IAD: reference scanning is now	Eelco Dolstra	3	-30/+45
	much faster.
2005-10-29	* Repair the referers table from the references table.	Rob Vermaas	1	-0/+3

2005-10-20	* Prevent uids from being used for more than one build	Eelco Dolstra	1	-36/+120
	simultaneously. We do this using exclusive locks on uid files in /nix/var/nix/userpool, e.g., /nix/var/nix/userpool/123 for uid 123.
2005-10-19	* Oops. Fixed-output derivations were broken.	Eelco Dolstra	1	-1/+0

2005-10-17	* Also kill all processes of the build user after the build. This is	Eelco Dolstra	1	-0/+8
	critical to prevent certain kinds of 0wnage.
2005-10-17	* Before starting a build under some uid, kill all current processes	Eelco Dolstra	1	-0/+48
	running under that uid.
2005-10-17	* Check that the build result is owned by the build user, and that	Eelco Dolstra	1	-2/+13
	nobody else has write permission to the build result. This catches most hack attempts.
2005-10-17	* Don't use FIFOs to make Nix create the output path on behalf of the	Eelco Dolstra	1	-68/+17
	builder. Instead, require that the Nix store has sticky permission (S_ISVTX); everyone can created files in the Nix store, but they cannot delete, rename or modify files created by others.
2005-10-17	* Beginning of secure multi-user Nix stores. If Nix is started as	Eelco Dolstra	3	-58/+214
	root (or setuid root), then builds will be performed under one of the users listed in the `build-users' configuration variables. This is to make it impossible to influence build results externally, allowing locally built derivations to be shared safely between users (see ASE-2005 paper). To do: only one builder should be active per build user.
2005-09-22	* Lets not go wild with templates.	Eelco Dolstra	1	-4/+6

2005-09-22	* Parse multi-valued options.	Eelco Dolstra	2	-15/+34

2005-09-21	* Configuration options for trusted local builds.	Eelco Dolstra	2	-5/+12

2005-09-20	* Typo.	Eelco Dolstra	1	-1/+1

2005-07-22	* Build dynamic libraries.	Eelco Dolstra	1	-2/+2

2005-05-10	* Ignore (with a warning) invalid garbage collector roots.	Eelco Dolstra	1	-1/+6

2005-05-10	* Typo.	Eelco Dolstra	1	-1/+1

2005-05-09	* Automatically upgrade the Berkeley DB environment if necessary.	Eelco Dolstra	2	-106/+133

2005-05-07	* Don't try to register GC roots in read-only mode.	Eelco Dolstra	1	-2/+2

2005-05-04	* Idem (constness fix).	Eelco Dolstra	1	-2/+2
	* `compare' in GCC 2.95 is broken.
2005-05-04	* GCC 2.95 compatibility fix in constness; strangely, I think this	Eelco Dolstra	1	-1/+1
	should not have worked at all.
2005-04-13	* Remove redundant message.	Eelco Dolstra	1	-4/+0

2005-04-12	* Garbage collector fix: allow deletion of paths that have invalid	Eelco Dolstra	1	-4/+4
	(but substitutable) referers.
2005-04-11	* Slightly nicer message.	Eelco Dolstra	1	-3/+3

2005-04-07	* `nix-store --add-fixed' to preload the outputs of fixed-output	Eelco Dolstra	2	-2/+68
	derivations. This is mostly to simplify the implementation of nix-prefetch-{url, svn}, which now work properly in setuid installations. * Enforce valid store names in `nix-store --add / --add-fixed'.
2005-03-25	* When finding live paths, the deriver need not be valid.	Eelco Dolstra	1	-1/+4

2005-03-25	* `nix-store --verify': repair bad referer mappings.	Eelco Dolstra	1	-6/+16

2005-03-24	* Create missing log and temproots directories automatically (reported	Eelco Dolstra	2	-13/+12
	by Rob).
2005-03-23	* Export the references graph to the build hook.	Eelco Dolstra	1	-14/+30

2005-03-23	* `nix-store --register-validity': allow a path to refer to a path	Eelco Dolstra	2	-13/+50
	listed later in the list of new valid paths.
2005-03-23	* nix-store: `--isvalid' -> `--check-validity', `--validpath' ->	Eelco Dolstra	2	-1/+2
	`--register-validity'. * `nix-store --register-validity': read arguments from stdin, and allow the references and deriver to be set.
2005-03-14	* Bug in clearSubstitutes().	Eelco Dolstra	1	-1/+2

2005-03-03	* Don't use fork() in copyPath(), but a string buffer.	Eelco Dolstra	1	-47/+14

2005-03-03	* Increase Berkeley DB limits a bit more.	Eelco Dolstra	2	-7/+26
	* Maintain the cleanup invariant in clearSubstitutes().
2005-03-02	* `nix-store -q --hash' to quickly query the hash of the contents of a	Eelco Dolstra	2	-0/+11
	store path (which is stored in the database).
2005-02-23	* When multiple derivations are specified in `nix-store -r', don't	Eelco Dolstra	1	-62/+50
	continue building when one fails unless `--keep-going' is specified. * When `--keep-going' is specified, print out the set of failing derivations at the end (otherwise it can be hard to find out which failed).
2005-02-22	* Support for fixed-output hashes over directory trees (i.e., over the	Eelco Dolstra	1	-14/+26
	NAR dump of the path).
2005-02-22	* Compatibility hack so that Nixpkgs can continue to do hash checking	Eelco Dolstra	1	-0/+9
	in `fetchurl' in Nix <= 0.7, but doesn't in Nix 0.8.
2005-02-18	* Subtle bug in the builder: if a subgoal that is instantiated	Eelco Dolstra	1	-31/+30
	multiple times is also a top-level goal, then the second and later instantiations would never be created because there would be a stable pointer to the first one that would keep it alive in the WeakGoalMap. * Some tracing code for debugging this kind of problem.
