2012-07-17	Add function queryPathFromHashPart()	Eelco Dolstra	1	-0/+12
	To implement binary caches efficiently, Hydra needs to be able to map the hash part of a store path (e.g. "gbg...zr7") to the full store path (e.g. "/nix/store/gbg...kzr7-subversion-1.7.5"). (The binary cache mechanism uses hash parts as a key for looking up store paths to ensure privacy.) However, doing a search in the Nix store for /nix/store/<hash>* is expensive since it requires reading the entire directory. queryPathFromHashPart() prevents this by doing a cheap database lookup.
2012-06-27	nix-store -r: do substitutions in parallel	Eelco Dolstra	1	-2/+2
	I.e. when multiple non-derivation arguments are passed to ‘nix-store -r’ to be substituted, do them in parallel.
2012-05-29	Reserve some disk space for the garbage collector	Eelco Dolstra	1	-2/+4
	We can't open a SQLite database if the disk is full. Since this prevents the garbage collector from running when it's most needed, we reserve some dummy space that we can free just before doing a garbage collection. This actually revives some old code from the Berkeley DB days. Fixes #27.
2012-04-30	* Add an option ‘build-use-substitutes’, which can be set to ‘false’	Eelco Dolstra	1	-0/+3
	to disable use of substitutes; i.e., force building from source. Fixes Nix/221.
2012-03-26	Remove the --max-links GC option	Eelco Dolstra	1	-1/+1
	We don't need this anymore now that current filesystems support more than 32,000 files in a directory.
2012-02-09	Use data() instead of c_str() where appropriate	Eelco Dolstra	1	-2/+2

2011-12-20	* Fix the build.	Eelco Dolstra	1	-1/+1

2011-12-16	* Sync with the trunk.	Eelco Dolstra	1	-23/+28

2011-12-16	* importPath() -> importPaths(). Because of buffering of the input	Eelco Dolstra	1	-20/+21
	stream it's now necessary for the daemon to process the entire sequence of exported paths, rather than letting the client do it.
2011-12-16	* Make the import operation through the daemon much more efficient	Eelco Dolstra	1	-3/+3
	(way fewer roundtrips) by allowing the client to send data in bigger chunks. * Some refactoring.
2011-12-15	* Refactoring: move sink/source buffering into separate classes.	Eelco Dolstra	1	-1/+1
	* Buffer the HashSink. This speeds up hashing a bit because it prevents lots of calls to the hash update functions (e.g. nix-hash went from 9.3s to 8.7s of user time on the closure of my /var/run/current-system).
2011-12-14	* Buffer writes in FdSink. This significantly reduces the number of	Eelco Dolstra	1	-0/+4
	system calls / context switches when dumping a NAR and in the worker protocol.
2011-12-01	* When doing "nix-store --add-fixed" without "--recursive" via the Nix	Eelco Dolstra	1	-1/+1
	daemon (which is an error), print a nicer error message than "Connection reset by peer" or "broken pipe". * In the daemon, log errors that occur during request parameter processing.
2011-11-06	Include all outputs of derivations in the closure of explicitly-passed ↵	Shea Levy	1	-0/+10
	derivation paths This required adding a queryOutputDerivationNames function in the store API
2011-04-19	* Handle error messages from the Nix worker containing the `%'	Eelco Dolstra	1	-1/+1
	character. (Nix/216)
2010-12-17	* Propagate the "100" exit status for failed builds through the Nix	Eelco Dolstra	1	-2/+5
	daemon.
2010-11-17	* Before a build, show the disk space that the downloaded store paths	Eelco Dolstra	1	-2/+2
	will approximately require.
2010-11-17	* Implement RemoteStore::queryPathInfo().	Eelco Dolstra	1	-1/+13

2010-11-16	* Store the size of a store path in the database (to be precise, the	Eelco Dolstra	1	-0/+6
	size of the NAR serialisation of the path, i.e., `nix-store --dump PATH'). This is useful for Hydra.
2010-08-30	* When using the build hook, distinguish between the stderr of the	Eelco Dolstra	1	-8/+1
	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.
2010-08-24	* Sync with the trunk.	Eelco Dolstra	1	-0/+3

2010-08-12	* Make --cores work when building through the Nix daemon.	Eelco Dolstra	1	-0/+3

2010-08-04	* Sync with the trunk.	Eelco Dolstra	1	-0/+2

2010-06-24	Include <cstring> to ensure that strcpy(), strlen(), and memset() are declared.	Peter Simons	1	-0/+2
	An "using namespace std" was added locally in those functions that refer to names from <cstring>. That is not pretty, but it's a very portable solution, because strcpy() and friends will be found in both the 'std' and in the global namespace.
2010-05-04	* Allow unprivileged users to do `nix-store --clear-failed-paths' and	Eelco Dolstra	1	-0/+19
	`nix-store --query-failed-paths'.
2010-02-26	* Implement RemoteStore::queryValidPaths().	Eelco Dolstra	1	-1/+3

2010-02-25	* Implement RemoteStore::queryDerivationOutputs().	Eelco Dolstra	1	-1/+5

2010-02-22	* Get derivation outputs from the database instead of the .drv file,	Eelco Dolstra	1	-0/+6
	which requires more I/O.
2009-11-20	* Remove the --use-atime / --max-atime garbage collector flags. Many	Eelco Dolstra	1	-2/+3
	(Linux) machines no longer maintain the atime because it's too expensive, and on the machines where --use-atime is useful (like the buildfarm), reading the atimes on the entire Nix store takes way too much time to make it practical.
2009-04-21	* Use foreach in a lot of places.	Eelco Dolstra	1	-2/+1

2008-12-16	* Pass --use-atime / --max-atime to the daemon.	Eelco Dolstra	1	-0/+4

2008-12-11	* Open the connection to the daemon lazily (on demand) so that	Eelco Dolstra	1	-4/+33
	read-only operations (like nix-env -qa) work properly when the daemon isn't running.
2008-12-03	* Pass HashType values instead of strings.	Eelco Dolstra	1	-3/+3

2008-12-03	* Unify the treatment of sources copied to the store, and recursive	Eelco Dolstra	1	-4/+5
	SHA-256 outputs of fixed-output derivations. I.e. they now produce the same store path: $ nix-store --add x /nix/store/j2fq9qxvvxgqymvpszhs773ncci45xsj-x $ nix-store --add-fixed --recursive sha256 x /nix/store/j2fq9qxvvxgqymvpszhs773ncci45xsj-x the latter being the same as the path that a derivation derivation { name = "x"; outputHashAlgo = "sha256"; outputHashMode = "recursive"; outputHash = "..."; ... }; produces. This does change the output path for such fixed-output derivations. Fortunately they are quite rare. The most common use is fetchsvn calls with SHA-256 hashes. (There are a handful of those is Nixpkgs, mostly unstable development packages.) * Documented the computation of store paths (in store-api.cc).
2008-11-12	* Some somewhat ad hoc mechanism to allow the build farm to monitor	Eelco Dolstra	1	-1/+4
	build progress.
2008-11-11	* Pass the --no-build-output flag to the daemon.	Eelco Dolstra	1	-0/+2

2008-08-14	* Backward compatibility check to prevent nixos-rebuild from barfing	Eelco Dolstra	1	-0/+1
	when upgrading Nix.
2008-08-04	* querySubstitutablePathInfo: work properly when run via the daemon.	Eelco Dolstra	1	-1/+10
	* --dry-run: print the paths that we don't know how to build/substitute.
2008-08-02	* Make nix-env --dry-run print the paths to be substituted correctly	Eelco Dolstra	1	-6/+7
	again. (After the previous substituter mechanism refactoring I didn't update the code that obtains the references of substitutable paths.) This required some refactoring: the substituter programs are now kept running and receive/respond to info requests via stdin/stdout.
2008-06-18	* Some refactoring: put the GC options / results in separate structs.	Eelco Dolstra	1	-13/+9
	* The garbage collector now also prints the number of blocks freed.
2008-04-09	* sockaddr_un doesn't allow path names of more than 108 characters.	Eelco Dolstra	1	-3/+15
	This isn't usually a problem, except that it causes tests to fail when performed in a directory with a very long path name. So chdir to the socket directory and use a relative path name.
2008-01-29	* nix-store --dump-db / --load-db to dump/load the Nix DB.	Eelco Dolstra	1	-0/+6
	* nix-store --register-validity: option to supply the content hash of each path. * Removed compatibility with Nix <= 0.7 stores.
2007-11-16	* Flag `--no-build-hook' to disable distributed builds.	Eelco Dolstra	1	-2/+6
	* queryDeriver in daemon mode: don't barf if the other side returns an empty string (which means there is no deriver).
2007-09-18	* Pass various options to the worker so that flags like -K or -j work	Eelco Dolstra	1	-2/+21
	in multi-user Nix (NIX-72). * Client/worker: exchange a protocol version number for future compatibility.
2007-08-12	* Get rid of the substitutes database table (NIX-47). Instead, if we	Eelco Dolstra	1	-6/+6
	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	-6/+12

2007-05-01	* Set a terminate() handler to ensure that we leave the BDB	Eelco Dolstra	1	-2/+2
	environment cleanly even when an exception is thrown from a destructor. We still crash, but we don't take all other Nix processes with us.
2007-02-21	* `nix-store --import' now also works in remote mode. The worker	Eelco Dolstra	1	-6/+24
	always requires a signature on the archive. This is to ensure that unprivileged users cannot add Trojan horses to the Nix store.
2007-02-21	* Support exportPath() in remote mode.	Eelco Dolstra	1	-4/+12

2007-02-21	* `nix-store --import': import an archive created by `nix-store	Eelco Dolstra	1	-0/+6
	--export' into the Nix store, and optionally check the cryptographic signatures against /nix/etc/nix/signing-key.pub. (TODO: verify against a set of public keys.)
