2014-01-21	Fix some clang warnings	Eelco Dolstra

2013-12-10	Garbage collector: Release locks on temporary root files	Eelco Dolstra
	This allows processes waiting for such locks to proceed during the trash deletion phase of the garbage collector.
2013-11-14	Remove nix-setuid-helper	Eelco Dolstra
	AFAIK, nobody uses it, it's not maintained, and it has no tests.
2013-10-22	For auto roots, show the intermediate link	Eelco Dolstra
	I.e. "nix-store -q --roots" will now show (for example) /home/eelco/Dev/nixpkgs/result rather than /nix/var/nix/gcroots/auto/53222qsppi12s2hkap8dm2lg8xhhyk6v
2013-07-12	Garbage collector: Don't follow symlinks arbitrarily	Eelco Dolstra
	Only indirect roots (symlinks to symlinks to the Nix store) are now supported.
2013-04-26	addAdditionalRoots(): Check each path only once	Eelco Dolstra

2013-03-08	Revert "Prevent config.h from being clobbered"	Eelco Dolstra
	This reverts commit 28bba8c44f484eae38e8a15dcec73cfa999156f6.
2013-03-07	Prevent config.h from being clobbered	Eelco Dolstra

2013-01-05	Delete a left-over trash directory before doing a GC	Eelco Dolstra

2013-01-04	Fix "0 store paths deleted" message	Eelco Dolstra

2013-01-03	Clear any immutable bits in the Nix store	Eelco Dolstra
	Doing this once makes subsequent operations like garbage collecting more efficient since we don't have to call makeMutable() first.
2012-12-20	Yet another rewrite of the garbage collector	Eelco Dolstra
	But this time it's obviously correct! No more segfaults due to infinite recursions for sure, etc. Also, move directories to /nix/store/trash instead of renaming them to /nix/store/bla-gc-<pid>. Then we can just delete /nix/store/trash at the end.
2012-12-19	If gc-keep-derivations is set, only keep the actual deriver	Eelco Dolstra
	This prevents zillions of derivations from being kept, and fixes an infinite recursion in the garbage collector (due to an obscure cycle that can occur with fixed-output derivations).
2012-09-19	Templatise tokenizeString()	Eelco Dolstra

2012-09-13	Vacuum the SQLite DB after running the garbage collector	Eelco Dolstra

2012-09-13	Delete paths in a component in topologically sorted order	Eelco Dolstra
	The outputs of a derivation can refer to each other (even though they cannot have cycles), so they have to be deleted in the right order. http://hydra.nixos.org/build/3026118
2012-09-12	Handle gc-keep-outputs and gc-keep-derivations both enabled	Eelco Dolstra
	If the options gc-keep-outputs and gc-keep-derivations are both enabled, you can get a cycle in the liveness graph. There was a hack to handle this, but it didn't work with multiple-output derivations, causing the garbage collector to fail with errors like ‘error: cannot delete path `...' because it is in use by `...'’. The garbage collector now handles strongly connected components in the liveness graph as a unit and decides whether to delete all or none of the paths in an SCC.
2012-08-27	Merge branch 'master' into no-manifests	Eelco Dolstra

2012-08-05	Handle amount of disk space saved by hard linking being negative	Eelco Dolstra
	Fixes bogus messages like "currently hard linking saves 17592186044416.00 MiB".
2012-08-01	Count bytes freed deleting unused links	Eelco Dolstra

2012-08-01	Drop the block count in the garbage collector	Eelco Dolstra

2012-08-01	nix-store --gc: Make ‘--max-freed 0’ do the right thing	Eelco Dolstra
	That is, delete almost nothing (it will still remove unused links from /nix/store/.links).
2012-08-01	removeUnusedLinks(): Print stats on disk space saved by hard linking	Eelco Dolstra

2012-07-30	Refactor settings processing	Eelco Dolstra
	Put all Nix configuration flags in a Settings object.
2012-07-23	Garbage collect unused links in /nix/store/.links	Eelco Dolstra
	Incremental optimisation requires creating links in /nix/store/.links to all files in the store. However, this means that if we delete a store path, no files are actually deleted because links in /nix/store/.links still exists. So we need to check /nix/store/.links for files with a link count of 1 and delete them.
2012-04-16	Fix obscure race condition in GC root creation	Eelco Dolstra
	This should fix rare Hydra errors of the form: error: symlinking `/nix/var/nix/gcroots/per-user/hydra/hydra-roots/7sfhs5fdmjxm8sqgcpd0pgcsmz1kq0l0-nixos-iso-0.1pre33785-33795' to `/nix/store/7sfhs5fdmjxm8sqgcpd0pgcsmz1kq0l0-nixos-iso-0.1pre33785-33795': File exists
2012-03-26	Mac OS X fix	Eelco Dolstra

2012-03-26	Delete non-directory valid paths right away	Eelco Dolstra
	It's unlikely that rename() is faster than unlink() on a regular file or symlink, so don't bother.
2012-03-26	Make the garbage collector more concurrent	Eelco Dolstra
	Make the garbage collector more concurrent by deleting valid paths outside the region where we're holding the global GC lock. This should greatly reduce the time during which new builds are blocked, since the deletion accounts for the vast majority of the time spent in the GC. To ensure that this is safe, the valid paths are invalidated and renamed to some arbitrary path while we're holding the lock. This ensures that we when we finally delete the path, it's not a (newly) valid or locked path.
2012-03-26	Remove the --max-links GC option	Eelco Dolstra
	We don't need this anymore now that current filesystems support more than 32,000 files in a directory.
2012-03-13	Ensure that Perl processes delete their entry in the temproots directory	Eelco Dolstra
	By moving the destructor object to libstore.so, it's also run when download-using-manifests and nix-prefetch-url exit. This prevents them from cluttering /nix/var/nix/temproots with stale files.
2012-03-05	Set the close-on-exec flag on file descriptors	Eelco Dolstra

2012-02-15	Don't use deletePath() to delete a single file	Eelco Dolstra

2012-02-09	Use data() instead of c_str() where appropriate	Eelco Dolstra

2011-12-30	* Move topoSortPaths() out of gc.cc.	Eelco Dolstra

2011-12-30	* Reject a build if there is a cycle among the outputs. This is	Eelco Dolstra
	necessary because existing code assumes that the references graph is acyclic.
2011-12-22	* Oops.	Eelco Dolstra

2011-12-22	* In the garbage collector, delete invalid paths before deleting	Eelco Dolstra
	unreachable paths. This matters when using --max-freed etc.: unreachable paths could become reachable again, so it's nicer to keep them if there is "real" garbage to be deleted. Also, don't use readDirectory() but read the Nix store and delete invalid paths in parallel. This reduces GC latency on very large Nix stores.
2011-12-22	* Drop unnecessary call to canonPath() (nixStore is already canonical).	Eelco Dolstra

2011-08-31	* Eliminate all uses of the global variable ‘store’ from libstore.	Eelco Dolstra
	This should also fix: nix-instantiate: ./../boost/shared_ptr.hpp:254: T* boost::shared_ptr<T>::operator->() const [with T = nix::StoreAPI]: Assertion `px != 0' failed. which was caused by hashDerivationModulo() calling the ‘store’ object (during store upgrades) before openStore() assigned it.
2010-10-14	* Wrap deleteFromStore() in a transaction. Otherwise there might be a	Eelco Dolstra
	race with other processes that add new referrers to a path, resulting in the garbage collector crashing with "foreign key constraint failed". (Nix/4) * Make --gc --print-dead etc. interruptible.
2010-08-31	`nix-store --verify' improvements:	Eelco Dolstra
	* If a path has disappeared, check its referrers first, and don't try to invalidate paths that have valid referrers. Otherwise we get a foreign key constraint violation. * Read the whole Nix store directory instead of statting each valid path, which is slower. * Acquire the global GC lock.
2010-08-30	* When using the build hook, distinguish between the stderr of the	Eelco Dolstra
	hook script proper, and the stdout/stderr of the builder. Only the latter should be saved in /nix/var/log/nix/drvs. * Allow the verbosity to be set through an option. * Added a flag --quiet to lower the verbosity level.
2010-08-30	* Disable the GC reachability check for now (when creating new roots),	Eelco Dolstra
	as it's hopelessly inefficient.
2010-03-08	* Set `gc-keep-outputs' or `gc-keep-derivations' to false with	Eelco Dolstra
	`--delete --ignore-liveness'.
2010-02-22	* Get derivation outputs from the database instead of the .drv file,	Eelco Dolstra
	which requires more I/O.
2010-02-22	* Revert r19650 (implement gc-keep-outputs by looking for derivations	Eelco Dolstra
	with the same name as the output) and instead use the DerivationOutputs table in the database, which is the correct way to to do things.
2010-02-02	* Remove most Cygwin-specific code. Cygwin 1.7 implements advisory	Eelco Dolstra
	POSIX locks, and simulates Unix-style file deletion semantics sufficiently. Note that this means that Nix won't work on Cygwin 1.5 anymore.
2010-01-25	* Make the garbage collector do the right thing when `gc-keep-outputs'	Eelco Dolstra
	is enabled by not depending on the deriver.
2009-11-24	* Randomise the order in which we delete entries to make the collector	Eelco Dolstra
	less biased towards deleting paths that come alphabetically first (e.g. /nix/store/000...). This matters when using --max-freed etc.
