2007-11-15	Added possibility to specify garbage collection levels for store paths; so ↵	Michael Raskin	1	-4/+15
	packages can share intermediate results of compilation and GC will collect it automatically while never touching tarballs, for example.
2007-08-28	* PathLocks::lockPaths: don't allow reacquiring a lock we already	Eelco Dolstra	1	-1/+3
	hold.
2007-08-12	* Get rid of the substitutes database table (NIX-47). Instead, if we	Eelco Dolstra	1	-0/+2
	need any info on substitutable paths, we just call the substituters (such as download-using-manifests.pl) directly. This means that it's no longer necessary for nix-pull to register substitutes or for nix-channel to clear them, which makes those operations much faster (NIX-95). Also, we don't have to worry about keeping nix-pull manifests (in /nix/var/nix/manifests) and the database in sync with each other. The downside is that there is some overhead in calling an external program to get the substitutes info. For instance, "nix-env -qas" takes a bit longer. Abolishing the substitutes table also makes the logic in local-store.cc simpler, as we don't need to store info for invalid paths. On the downside, you cannot do things like "nix-store -qR" on a substitutable but invalid path (but nobody did that anyway). * Never catch interrupts (the Interrupted exception).
2007-06-12	* Support queryDeriver() in multi-user installations.	Eelco Dolstra	1	-1/+1

2007-06-11	* Check against creation of GC roots in the store. Those roots don't	Eelco Dolstra	1	-1/+5
	work, because findRoots() stops when it encounters a symlink to the store. And of course the store is supposed to be read-only.
2007-03-19	* Undocumented option `gc-check-reachability' to allow reachability	Eelco Dolstra	1	-7/+9
	checking to be turned off on machines with way too many roots.
2007-02-21	* `nix-store -qR' and friends: print the paths sorted topologically	Eelco Dolstra	1	-2/+2
	under the references relation. This is useful for commands that want to copy paths to another Nix store in the right order.
2007-01-14	* Make the garbage collector more resilient to certain consistency	Eelco Dolstra	1	-3/+7
	errors: in-use paths now cause a warning, not a fatal error.
2006-12-05	* Better message.	Eelco Dolstra	1	-1/+1

2006-12-05	* Allow unprivileged users to run the garbage collector and to do	Eelco Dolstra	1	-4/+4
	`nix-store --delete'. But unprivileged users are not allowed to ignore liveness. * `nix-store --delete --ignore-liveness': ignore the runtime roots as well.
2006-12-05	* The determination of the root set should be made by the privileged	Eelco Dolstra	1	-56/+64
	process, so forward the operation. * Spam the user about GC misconfigurations (NIX-71). * findRoots: skip all roots that are unreadable - the warnings with which we spam the user should be enough.
2006-12-05	* findRoots: return a map from the symlink (outside of the store) to	Eelco Dolstra	1	-11/+16
	the store path (inside the store).
2006-12-05	* In addPermRoot, check that the root that we just registered can be	Eelco Dolstra	1	-17/+41
	found by the garbage collector. This addresses NIX-71 and is a particular concern in multi-user stores.
2006-12-04	* Add indirect root registration to the protocol so that unprivileged	Eelco Dolstra	1	-5/+10
	processes can register indirect roots. Of course, there is still the problem that the garbage collector can only read the targets of the indirect roots when it's running as root...
2006-12-02	* Move addTempRoot() to the store API, and add another function	Eelco Dolstra	1	-5/+12
	syncWithGC() to allow clients to register GC roots without needing write access to the global roots directory or the GC lock.
2006-12-02	* Remove SwitchToOriginalUser, we're not going to need it anymore.	Eelco Dolstra	1	-4/+1

2006-11-30	* Refactoring. There is now an abstract interface class StoreAPI	Eelco Dolstra	1	-8/+8
	containing functions that operate on the Nix store. One implementation is LocalStore, which operates on the Nix store directly. The next step, to enable secure multi-user Nix, is to create a different implementation RemoteStore that talks to a privileged daemon process that uses LocalStore to perform the actual operations.
2006-11-24	* Doh! Path sizes need to be computed recursively of course.	Eelco Dolstra	1	-6/+2
	(NIX-70)
2006-09-14	* Fix a huge gaping hole in nix-env w.r.t. the garbage collector.	Eelco Dolstra	1	-9/+14
	Nix-env failed to call addPermRoot(), which is necessary to safely add a new root. So if nix-env started after and finished before the garbage collector, the user environment (plus all other new stuff) it built might be garbage collected, leading to a dangling symlink chain in ~/.nix-profile... * Be more explicit if we block on the GC lock ("waiting for the big garbage collector lock..."). * Don't loop trying to create a new generation. It's not necessary anymore since profiles are locked nowadays.
2006-09-04	* Use a proper namespace.	Eelco Dolstra	1	-2/+11
	* Optimise header file usage a bit. * Compile the parser as C++.
2006-08-11	* `nix-store --gc --print-dead': print the total size of the store	Eelco Dolstra	1	-0/+9
	objects that would be freed.
2006-08-11	* Don't assume that paths returned by the runtime root finder are	Eelco Dolstra	1	-1/+1
	valid.
2006-07-20	* Use $(libexecdir) to find find-runtime-roots.pl.	Eelco Dolstra	1	-1/+1

2006-07-20	* Use debug().	Eelco Dolstra	1	-1/+1

2006-07-20	* Call find-runtime-roots.pl from the garbage collector to prevent	Eelco Dolstra	1	-0/+31
	running applications etc. from being garbage collected.
2006-06-20	* Concurrent GC on Cygwin.	Eelco Dolstra	1	-23/+57

2006-05-29	* Disable the concurrent garbage collector on Cygwin for now.	Eelco Dolstra	1	-0/+8

2006-05-11	* 64-bit compatibility fixes (for problems revealed by building on an Athlon	Eelco Dolstra	1	-1/+1
	64 running 64-bit SUSE). A patched ATerm library is required to run Nix succesfully.
2006-03-06	* `nix-env (-i\|-u) --dry-run' now shows exactly which missing paths	Eelco Dolstra	1	-1/+1
	will be built or substituted.
2005-12-23	* Added a flag `--ignore-liveness' to `nix-store --delete'. It	Eelco Dolstra	1	-2/+3
	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	1	-8/+19
	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	1	-2/+6
	(even when it is interrupted by a signal).
2005-12-13	* Change `referer' to `referrer' throughout. In particular, the	Eelco Dolstra	1	-2/+2
	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).
2005-05-10	* Ignore (with a warning) invalid garbage collector roots.	Eelco Dolstra	1	-1/+6

2005-03-25	* When finding live paths, the deriver need not be valid.	Eelco Dolstra	1	-1/+4

2005-03-24	* Create missing log and temproots directories automatically (reported	Eelco Dolstra	1	-12/+5
	by Rob).
2005-02-17	* Switch to the calling user context for some more operations in a	Eelco Dolstra	1	-2/+5
	setuid installation.
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	1	-2/+2
	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.
2005-02-08	* Updated `nix-store --verify' to the new schema.	Eelco Dolstra	1	-1/+1

2005-02-07	* `nix-store -qb' to query derivation environment bindings. Useful	Eelco Dolstra	1	-3/+3
	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.
2005-02-01	* A GC setting `gc-keep-outputs' to specify whether output paths of	Eelco Dolstra	1	-7/+17
	derivations should be kept.
2005-02-01	* Move root finding from `nix-collect-garbage' to `nix-store --gc'.	Eelco Dolstra	1	-5/+54
	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	1	-19/+42
	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	1	-0/+46
	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.
2005-01-31	* 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	1	-1/+11

2005-01-31	* Topologically sort paths under the references relation to ensure	Eelco Dolstra	1	-35/+77
	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	1	-0/+26
