2017-04-06Implement RemoteStore::queryMissing()Eelco Dolstra
This provides a significant speedup, e.g. 64 s -> 12 s for nix-build --dry-run -I nixpkgs=channel:nixos-16.03 '<nixpkgs/nixos/tests/misc.nix>' -A test on a cold local and CloudFront cache. The alternative is to use lots of concurrent daemon connections but that seems wasteful.
2016-11-09Merge branch 'ssh-store' of https://github.com/shlevy/nixEelco Dolstra
2016-09-02Implement nar-based addToStore for remote-storeShea Levy
2016-09-02Add narFromPath op to nix daemonShea Levy
2016-06-01Make the store directory a member variable of StoreEelco Dolstra
2016-05-04Add a Store::addToStore() variant that accepts a NAREelco Dolstra
As a side effect, this ensures that signatures are propagated when copying paths between stores. Also refactored import/export to make use of this.
2016-04-20RemoteStore: Propagate InvalidPath exceptions from the daemonEelco Dolstra
2016-04-19Move path info caching from BinaryCacheStore to StoreEelco Dolstra
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().
2016-04-05Add "nix copy-sigs" commandEelco Dolstra
This imports signatures from one store into another. E.g. $ nix copy-sigs -r /run/current-system -s https://cache.nixos.org/ imported 595 signatures
2016-03-30LocalStore: Keep track of ultimately trusted pathsEelco Dolstra
These are content-addressed paths or outputs of locally performed builds. They are trusted even if they don't have signatures, so "nix verify-paths" won't complain about them.
2015-12-02daemon: Add 'buildMode' parameter to 'buildPaths' RPCLudovic Courtès
2015-09-03Implement buildDerivation() via the daemonEelco Dolstra
2015-06-02Add a ‘verifyStore’ RPCLudovic Courtès
Hello! The patch below adds a ‘verifyStore’ RPC with the same signature as the current LocalStore::verifyStore method. Thanks, Ludo’. >From aef46c03ca77eb6344f4892672eb6d9d06432041 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ludovic=20Court=C3=A8s?= <ludo@gnu.org> Date: Mon, 1 Jun 2015 23:17:10 +0200 Subject: [PATCH] Add a 'verifyStore' remote procedure call.

2014-07-24Remove some dead codeEelco Dolstra
2013-08-07Run the daemon worker on the same CPU as the clientEelco Dolstra
On a system with multiple CPUs, running Nix operations through the daemon is significantly slower than "direct" mode: $ NIX_REMOTE= nix-instantiate '<nixos>' -A system real 0m0.974s user 0m0.875s sys 0m0.088s $ NIX_REMOTE=daemon nix-instantiate '<nixos>' -A system real 0m2.118s user 0m1.463s sys 0m0.218s The main reason seems to be that the client and the worker get moved to a different CPU after every call to the worker. This patch adds a hack to lock them to the same CPU. With this, the overhead of going through the daemon is very small: $ NIX_REMOTE=daemon nix-instantiate '<nixos>' -A system real 0m1.074s user 0m0.809s sys 0m0.098s
2013-03-08Revert "Prevent config.h from being clobbered"Eelco Dolstra
This reverts commit 28bba8c44f484eae38e8a15dcec73cfa999156f6.
2013-03-07Prevent config.h from being clobberedEelco Dolstra
2013-02-19Add `Settings::nixDaemonSocketFile'.Ludovic Courtès
2012-12-20nix-store -q --roots: Respect the gc-keep-outputs/gc-keep-derivations settingsEelco Dolstra
So if a path is not garbage solely because it's reachable from a root due to the gc-keep-outputs or gc-keep-derivations settings, ‘nix-store -q --roots’ now shows that root.

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.
2012-05-29Reserve 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.
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* 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.
2011-11-06Include 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.
2010-11-17* 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
2010-05-04* Allow unprivileged users to do `nix-store --clear-failed-paths' andEelco Dolstra
`nix-store --query-failed-paths'.
2010-02-26* Implement RemoteStore::queryValidPaths().Eelco Dolstra
2010-02-25* Implement RemoteStore::queryDerivationOutputs().Eelco Dolstra
2008-12-16* Pass --use-atime / --max-atime to the daemon.Eelco Dolstra
2008-11-11* Pass the --no-build-output flag to the daemon.Eelco Dolstra
2008-08-14* Backward compatibility check to prevent nixos-rebuild from barfingEelco Dolstra
when upgrading Nix.
2008-08-04* querySubstitutablePathInfo: work properly when run via the daemon.Eelco Dolstra
* --dry-run: print the paths that we don't know how to build/substitute.
2008-06-18* Some refactoring: put the GC options / results in separate structs.Eelco Dolstra
* The garbage collector now also prints the number of blocks freed.
2007-11-16* Flag `--no-build-hook' to disable distributed builds.Eelco Dolstra
* queryDeriver in daemon mode: don't barf if the other side returns an empty string (which means there is no deriver).
