2016-09-16	Make computeFSClosure() single-threaded again	Eelco Dolstra	2	-0/+50
	The fact that queryPathInfo() is synchronous meant that we needed a thread for every concurrent binary cache lookup, even though they end up being handled by the same download thread. Requiring hundreds of threads is not a good idea. So now there is an asynchronous version of queryPathInfo() that takes a callback function to process the result. Similarly, enqueueDownload() now takes a callback rather than returning a future. Thus, a command like nix path-info --store https://cache.nixos.org/ -r /nix/store/slljrzwmpygy1daay14kjszsr9xix063-nixos-16.09beta231.dccf8c5 that returns 4941 paths now takes 1.87s using only 2 threads (the main thread and the downloader thread). (This is with a prewarmed CloudFront.)

2016-06-09	Use O_CLOEXEC in most places	Eelco Dolstra	3	-7/+11

2016-06-02	createTempDir(): Don't do a chown on Linux	Eelco Dolstra	1	-0/+2
	It's not needed and can cause problems in a user namespace.
2016-06-02	Allow setting the state directory as a store parameter	Eelco Dolstra	1	-3/+14
	E.g. "local?store=/tmp/store&state=/tmp/var".
2016-05-31	use $(LIBLZMA_LIBS) instead of -llzma	Dmitry Kalinkin	1	-1/+1
	This is needed in case of non-standard lzma installation path that will be specified in pkgconfig manifest as extra -L option for LDFLAGS.
2016-05-04	Cleanup: Remove singleton()	Eelco Dolstra	1	-9/+0

2016-05-04	Do compression in a sink	Eelco Dolstra	3	-92/+186

2016-05-04	Add a Store::addToStore() variant that accepts a NAR	Eelco Dolstra	2	-10/+10
	As a side effect, this ensures that signatures are propagated when copying paths between stores. Also refactored import/export to make use of this.
2016-05-04	Fix segfault in xz compression/decompression	Eelco Dolstra	1	-2/+2

2016-05-04	Add a copyStorePath() utility function	Eelco Dolstra	1	-0/+7

2016-04-29	Support Git repos in the Nix path	Eelco Dolstra	2	-0/+10
	E.g. $ nix-build -I nixpkgs=git://github.com/NixOS/nixpkgs '<nixpkgs>' -A hello This is not extremely useful yet because you can't specify a branch/revision.
2016-04-29	BinaryCacheStore: Support bzip2 compression	Eelco Dolstra	2	-35/+117

2016-04-29	BinaryCacheStore: Support "none" compression method	Eelco Dolstra	2	-6/+29

2016-04-29	Eliminate the substituter mechanism	Eelco Dolstra	1	-0/+12
	Substitution is now simply a Store -> Store copy operation, most typically from BinaryCacheStore to LocalStore.
2016-04-25	Improved logging abstraction	Eelco Dolstra	5	-168/+165
	This also gets rid of --log-type, since the nested log type isn't useful in a multi-threaded situation, and nobody cares about the "pretty" log type.
2016-04-22	Factor out parallel processing of work items that have dependencies	Eelco Dolstra	1	-0/+60

2016-04-22	ThreadPool: Start doing work as soon as work items are enqueued	Eelco Dolstra	2	-59/+84

2016-04-22	Make compression interruptible	Eelco Dolstra	1	-1/+3

2016-04-21	nix --help: Show short flags	Eelco Dolstra	2	-4/+6

2016-04-20	Cache path info lookups in SQLite	Eelco Dolstra	4	-7/+52
	This re-implements the binary cache database in C++, allowing it to be used by other Store backends, in particular the S3 backend.
2016-04-19	Move path info caching from BinaryCacheStore to Store	Eelco Dolstra	2	-0/+12
	Caching path info is generally useful. For instance, it speeds up "nix path-info -rS /run/current-system" (i.e. showing the closure sizes of all paths in the closure of the current system) from 5.6s to 0.15s. This also eliminates some APIs like Store::queryDeriver() and Store::queryReferences().
2016-04-15	BinaryCacheStore::readFile(): Return a shared_ptr to a string	Eelco Dolstra	2	-4/+6
	This allows readFile() to indicate that a file doesn't exist, and might eliminate some large string copying.
2016-04-08	Make LocalStore thread-safe	Eelco Dolstra	1	-3/+3
	Necessary for multi-threaded commands like "nix verify-paths".
2016-03-31	Add missing -pthread	Eelco Dolstra	1	-1/+1
	https://hydra.nixos.org/build/33908385
2016-03-29	Improve SIGINT handling in multi-threaded programs	Eelco Dolstra	3	-5/+10
	The flag remembering whether an Interrupted exception was thrown is now thread-local. Thus, all threads will (eventually) throw Interrupted. Previously, one thread would throw Interrupted, and then the other threads wouldn't see that they were supposed to quit.
2016-03-29	Add "nix verify-paths" command	Eelco Dolstra	4	-2/+135
	Unlike "nix-store --verify-path", this command verifies signatures in addition to store path contents, is multi-threaded (especially useful when verifying binary caches), and has a progress indicator. Example use: $ nix verify-paths --store https://cache.nixos.org -r $(type -p thunderbird) ... [17/132 checked] checking ‘/nix/store/rawakphadqrqxr6zri2rmnxh03gqkrl3-autogen-5.18.6’
2016-03-15	Fix Darwin build	Eelco Dolstra	1	-0/+1
	http://hydra.nixos.org/build/33279996
2016-03-04	Eliminate some large string copying	Eelco Dolstra	2	-3/+5

2016-03-02	Fix reading symlinks	Eelco Dolstra	1	-1/+1
	The st_size field of a symlink doesn't have to be correct, e.g. for /dev/fd symlinks.
2016-03-02	FdSource: track number of bytes read	Eelco Dolstra	2	-5/+8

2016-02-25	Merge branch 'master' into new-cli	Eelco Dolstra	1	-0/+1

2016-02-25	Add NAR / Store accessor abstraction	Eelco Dolstra	1	-0/+1
	This is primary to allow hydra-queue-runner to extract files like "nix-support/hydra-build-products" from NARs in binary caches.
2016-02-25	Fix short boolean flags	Eelco Dolstra	1	-1/+1

2016-02-25	Merge branch 'master' into new-cli	Eelco Dolstra	13	-97/+515

2016-02-24	deletePath(): Succeed if path doesn't exist	Eelco Dolstra	2	-6/+10
	Also makes it robust against concurrent deletions.
2016-02-24	BinaryCacheStore: Implement addToStore()	Eelco Dolstra	2	-4/+16
	So now you can do $ NIX_REMOTE=file:///tmp/binary-cache nix-instantiate '<nixpkgs>' -A hello and lots of other operations.
2016-02-24	Typo	Eelco Dolstra	1	-2/+2

2016-02-24	Move BinaryCacheStore / LocalBinaryCacheStore from Hydra	Eelco Dolstra	1	-0/+84
	So you can now do: $ NIX_REMOTE=file:///tmp/binary-cache nix-store -qR /nix/store/...
2016-02-24	std::condition_variable_any -> std::condition_variable	Eelco Dolstra	2	-11/+11
	The latter is supposed to be more efficient.
