2012-08-22Receive reserveSpace before calling startWork()Eelco Dolstra
Otherwise we can get a SIGPOLL. Reported by Ludovic.

2012-07-17Add function queryPathFromHashPart()Eelco Dolstra
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.
2012-07-11Replace hasSubstitutes() with querySubstitutablePaths()Eelco Dolstra
querySubstitutablePaths() takes a set of paths, so this greatly reduces daemon <-> client latency.
2012-07-11Add a function queryValidPaths()Eelco Dolstra
queryValidPaths() combines multiple calls to isValidPath() in one. This matters when using the Nix daemon because it reduces latency. For instance, on "nix-env -qas \*" it reduces execution time from 5.7s to 4.7s (which is indistinguishable from the non-daemon case).
2012-07-11Rename queryValidPaths() to queryAllValidPaths()Eelco Dolstra
2012-07-11Implement querySubstitutablePathInfos() in the daemonEelco Dolstra
Also removed querySubstitutablePathInfo().
2012-06-27nix-store -r: do substitutions in parallelEelco Dolstra
I.e. when multiple non-derivation arguments are passed to ‘nix-store -r’ to be substituted, do them in parallel.
2012-06-18Support socket-based, on-demand activation of the Nix daemon with systemdEelco Dolstra
Systemd can start the Nix daemon on demand when the Nix daemon socket is first accessed. This is signalled through the LISTEN_FDS environment variable, so all we need to do is check for that and then use file descriptor 3 as the listen socket instead of creating one ourselves.
2012-05-29Reserve some disk space for the garbage collectorEelco Dolstra
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
to disable use of substitutes; i.e., force building from source. Fixes Nix/221.
2012-04-15Set a few more close-on-exec flagsEelco Dolstra
2012-03-26Remove the --max-links GC optionEelco Dolstra
We don't need this anymore now that current filesystems support more than 32,000 files in a directory.
2012-03-13Ensure that Perl processes delete their entry in the temproots directoryEelco 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.
2012-03-05nix-worker: put the pid of the caller in argv[1]Eelco Dolstra
This is useful for debugging.
2012-02-09Use data() instead of c_str() where appropriateEelco Dolstra
2011-12-20* Fix the build.Eelco Dolstra
2011-12-16* Sync with the trunk.Eelco Dolstra
2011-12-16* importPath() -> importPaths(). Because of buffering of the inputEelco Dolstra
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* Avoid expensive conversions from char arrays to STL strings.Eelco Dolstra
2011-12-16* Make the import operation through the daemon much more efficientEelco Dolstra
(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
* 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 ofEelco Dolstra
system calls / context switches when dumping a NAR and in the worker protocol.
2011-12-01* Slight improvement.Eelco Dolstra
2011-12-01* When doing "nix-store --add-fixed" without "--recursive" via the NixEelco Dolstra
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.
2011-11-06Include all outputs of derivations in the closure of explicitly-passed ↵Shea Levy
derivation paths This required adding a queryOutputDerivationNames function in the store API
2010-12-17* Propagate the "100" exit status for failed builds through the NixEelco Dolstra
daemon.
2010-12-13* Update some comments.Eelco Dolstra
2010-11-17* Before a build, show the disk space that the downloaded store pathsEelco Dolstra
will approximately require.
2010-11-17* Implement RemoteStore::queryPathInfo().Eelco Dolstra
2010-08-24* Sync with the trunk.Eelco Dolstra
2010-08-12* Make --cores work when building through the Nix daemon.Eelco Dolstra
2010-08-04* Sync with the trunk.Eelco Dolstra
2010-06-24Include <cstring> to ensure that strcpy(), strlen(), and memset() are declared.Peter Simons
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' andEelco Dolstra
`nix-store --query-failed-paths'.
2010-04-19* Drop the dependency on the ATerm library.Eelco Dolstra
2010-03-02* When using the included sqlite/aterm libraries, build withEelco Dolstra
--enable-shared. * In libutil/libstore/libexpr etc., link against sqlite and aterm. * Some more header file hygiene.
2010-02-26* Implement RemoteStore::queryValidPaths().Eelco Dolstra
2010-02-25* Implement RemoteStore::queryDerivationOutputs().Eelco Dolstra
2010-02-24* `helpText' is now zero-terminated.Eelco Dolstra
2010-02-24* ADDITIONAL_NETWORK_LIBS -> LIBS.Eelco Dolstra
2010-02-24* Add ${sqlite_lib} everywhere. Just adding it in `libstore' doesn'tEelco Dolstra
work on x86_64 when sqlite is compiled statically.
2009-11-20* Remove the --use-atime / --max-atime garbage collector flags. ManyEelco Dolstra
(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.
2009-11-06* Remove support for old (before Nix 0.12pre12020) databases.Eelco Dolstra
2009-10-08Added optional parameter which adds -lnsl -lsocket to make the Nix package ↵Sander van der Burg
manager work on OpenSolaris
