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.
2005-02-17	* Switch to the calling user context for some more operations in a	Eelco Dolstra	1	-2/+5
	setuid installation.
2005-02-17	* Put build logs in $prefix/var/nix/log/drvs/.	Eelco Dolstra	1	-1/+1

2005-02-14	* It is now possible to add store derivations or paths directly to a	Eelco Dolstra	2	-0/+14
	user environment, e.g., $ nix-env -i /nix/store/z58v41v21xd3ywrqk1vmvdwlagjx7f10-aterm-2.3.1.drv or $ nix-env -i /nix/store/hsyj5pbn0d9iz7q0aj0fga7cpaadvp1l-aterm-2.3.1 This is useful because it allows Nix expressions to be bypassed entirely. For instance, if only a nix-pull manifest is provided, plus the top-level path of some component, it can be installed without having to supply the Nix expression (e.g., for obfuscation, or to be independent of Nix expression language changes or context dependencies).
2005-02-14	* Implement the `gc-keep-derivations' global configuretion flag.	Eelco Dolstra	1	-1/+14

2005-02-14	* Global configuration option `env-keep-derivations' to store pointer	Eelco Dolstra	3	-3/+15
	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.
2005-02-14	* Type error in constructor call (caught by GCC 3.3, but not 3.4!).	Eelco Dolstra	1	-1/+1

2005-02-11	* Input sources should be in the set of all referenceable paths too.	Eelco Dolstra	2	-6/+6

2005-02-09	* Commit more often to prevent out-of-memory errors.	Eelco Dolstra	3	-4/+22

2005-02-09	* Propagate the deriver of a path through the substitute mechanism.	Eelco Dolstra	3	-7/+18
	* 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	* Automatically upgrade <= 0.7 Nix stores to the new schema (so that	Eelco Dolstra	5	-22/+141
	existing user environments continue to work). * `nix-store --verify': detect incomplete closures.
2005-02-08	* Subflag in `--verify': `nix-store --verify --check-contents' checks	Eelco Dolstra	2	-10/+36
	that the contents of store paths has not changed by comparing hashes of their current contents to the hashes stored in the database.
2005-02-08	* Updated `nix-store --verify' to the new schema.	Eelco Dolstra	5	-24/+104

2005-02-07	* `nix-store -qb' to query derivation environment bindings. Useful	Eelco Dolstra	3	-5/+28
	for finding build-time dependencies (possibly after a build). E.g., $ nix-store -qb aterm $(nix-store -qd $(which strc)) /nix/store/jw7c7s65n1gwhxpn35j9rgcci6ilzxym-aterm-2.3.1 * Arguments to nix-store can be files within store objects, e.g., /nix/store/jw7c...-aterm-2.3.1/bin/baffle. * Idem for garbage collector roots.
2005-02-07	* Maintain a database table (`derivers') that maps output paths to the	Eelco Dolstra	3	-11/+59
	derivation that produced them. * `nix-store -qd PATH' prints out the derivation that produced a path.
2005-02-01	* A GC setting `gc-keep-outputs' to specify whether output paths of	Eelco Dolstra	3	-7/+75
	derivations should be kept.
2005-02-01	* Move root finding from `nix-collect-garbage' to `nix-store --gc'.	Eelco Dolstra	2	-14/+69
	This was necessary becase root finding must be done after acquisition of the global GC lock. This makes `nix-collect-garbage' obsolete; it is now just a wrapper around `nix-store --gc'. * Automatically remove stale GC roots (i.e., indirect GC roots that point to non-existent paths).
2005-02-01	* nix-build: use an indirection scheme to make it easier for users to	Eelco Dolstra	2	-20/+44
	get rid of GC roots. Nix-build places a symlink `result' in the current directory. Previously, removing that symlink would not remove the store path being linked to as a GC root. Now, the GC root created by nix-build is actually a symlink in `/nix/var/nix/gcroots/auto' to `result'. So if that symlink is removed the GC root automatically becomes invalid (since it can no longer be resolved). The root itself is not automatically removed - the garbage collector should delete dangling roots.
2005-02-01	* nix-store, nix-instantiate: added an option `--add-root' to	Eelco Dolstra	4	-3/+54
	immediately add the result as a permanent GC root. This is the only way to prevent a race with the garbage collector. For instance, the old style ln -s $(nix-store -r $(nix-instantiate foo.nix)) \ /nix/var/nix/gcroots/result has two time windows in which the garbage collector can interfere (by GC'ing the derivation and the output, respectively). On the other hand, nix-store --add-root /nix/var/nix/gcroots/result -r \ $(nix-instantiate --add-root /nix/var/nix/gcroots/drv \ foo.nix) is safe. * nix-build: use `--add-root' to prevent GC races.
2005-02-01	* Add missing files to dist.	Eelco Dolstra	2	-3/+8
	* Fix GC and substitute bugs related to self-references. Add a regression test.
2005-01-31	* Acquire a global GC lock to prevent new temporary root files from	Eelco Dolstra	1	-15/+29
	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	* Add a test for a more subtle race: a process starting after the	Eelco Dolstra	1	-2/+20
	temporary root files have been read but creating outputs before the store directory has been read.
2005-01-31	* Automatically remove temporary root files.	Eelco Dolstra	2	-1/+16

2005-01-31	* Topologically sort paths under the references relation to ensure	Eelco Dolstra	2	-38/+84
	that they are deleted in an order that maintains the closure invariant. * Presence of a path in a temporary roots file does not imply that all paths in its closure are also present, so add the closure.
2005-01-31	* Don't delete active lock files.	Eelco Dolstra	3	-4/+31

2005-01-31	* Start of concurrent garbage collection. Processes write temporary	Eelco Dolstra	4	-98/+166
	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.
2005-01-28	* Only invalidate paths when they are in fact valid.	Eelco Dolstra	1	-1/+2

2005-01-27	* Fix deadlock.	Eelco Dolstra	1	-1/+1

2005-01-27	* Update referers mappings when updating/clearing the references	Eelco Dolstra	1	-7/+27
	mapping. * Do things in the right order in invalidatePath().
2005-01-27	* Fix and simplify the garbage collector (it's still not concurrent,	Eelco Dolstra	5	-24/+78
	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.
2005-01-27	* Make lock removal safe by signalling to blocked processes that the	Eelco Dolstra	2	-24/+45
	lock they are waiting on has become stale (we do this by writing a meaningless token to the unlinked file).
2005-01-25	* Maintain the references/referers relation also for derivations.	Eelco Dolstra	6	-80/+46
	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	3	-20/+11
	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	2	-11/+36
	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.
