2017-05-11 Change the meaning of info.ultimateEelco Dolstra1-3/+2
It now means "paths that were built locally". It no longer includes paths that were added locally. For those we don't need info.ultimate, since we have the content-addressability assertion (info.ca).
2017-05-02 build-remote: Fix fallback to other machines when connecting failsEelco Dolstra1-0/+4
Opening an SSHStore or LegacySSHStore does not actually establish a connection, so the try/catch block here did nothing. Added a Store::connect() method to test whether a connection can be established.
2017-05-01 build-remote: Don't require signaturesEelco Dolstra1-5/+2
This restores the old behaviour.
2017-05-01 Support arbitrary store URIs in nix.machinesEelco Dolstra1-6/+17
For backwards compatibility, if the URI is just a hostname, ssh:// (i.e. LegacySSHStore) is prepended automatically. Also, all fields except the URI are now optional. For example, this is a valid nix.machines file: local?root=/tmp/nix This is useful for testing the remote build machinery since you don't have to mess around with ssh.
2017-05-01 Add a dummy Store::buildPaths() methodEelco Dolstra1-7/+13
This default implementation of buildPaths() does nothing if all requested paths are already valid, and throws an "unsupported operation" error otherwise. This fixes a regression introduced by c30330df6f67c81986dfb124631bc756c8e58c0d in binary cache and legacy SSH stores.
2017-04-13 Add a Config class to simplify adding configuration settingsEelco Dolstra1-5/+20
The typical use is to inherit Config and add Setting<T> members: class MyClass : private Config { Setting<int> foo{this, 123, "foo", "the number of foos to use"}; Setting<std::string> bar{this, "blabla", "bar", "the name of the bar"}; MyClass() : Config(readConfigFile("/etc/my-app.conf")) { std::cout << foo << "\n"; // will print 123 unless overriden } }; Currently, this is used by Store and its subclasses for store parameters. You now get a warning if you specify a non-existant store parameter in a store URI.
2017-04-10 Minor cleanupEelco Dolstra1-6/+1
Also, possible fix for #1310 on 32-bit systems.
2017-04-06 Implement RemoteStore::queryMissing()Eelco Dolstra1-1/+1
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.
2017-04-06 Add a method to allow hydra-queue-runner to flush the path info cacheEelco Dolstra1-5/+7
2017-04-06 nix-daemon: Disable path info cacheEelco Dolstra1-1/+6
This is useless because the client also caches path info, and can cause problems for long-running clients like hydra-queue-runner (i.e. it may return cached info about paths that have been garbage-collected).
2017-03-16 copyPaths(): Use queryValidPaths() to reduce SSH latencyEelco Dolstra1-3/+5
2017-03-16 LegacySSHStore: Provide a faster implementation of computeFSClosure()Eelco Dolstra1-1/+1
This avoids the latency of the standard implementation, which can make a huge difference (e.g. 16.5s -> 0.5s on a NixOS system closure).
2017-03-15 Store: Add a method for getting build logsEelco Dolstra1-0/+8
This allows various Store implementations to provide different ways to get build logs. For example, BinaryCacheStore can get the build logs from the binary cache. Also, remove the log-servers option since we can use substituters for this.
2017-03-03 build-remote: Don't use a SSH masterEelco Dolstra1-0/+2
This is unnecessary because we make only one connection.
2017-02-22 RemoteStore::addToStore(): Pass content-addressability assertionEelco Dolstra1-1/+6
... and use this in Downloader::downloadCached(). This fixes $ nix-build https://nixos.org/channels/nixos-16.09-small/nixexprs.tar.xz -A hello error: cannot import path ‘/nix/store/csfbp1s60dkgmk9f8g0zk0mwb7hzgabd-nixexprs.tar.xz’ because it lacks a valid signature
2017-02-07 Merge branch 'nix-copy-closure-c++' of https://github.com/shlevy/nixEelco Dolstra1-1/+1
2017-02-07 copyStorePath(): Don't require signatures for "trusted" storesEelco Dolstra1-0/+4
For example, SSH stores could be trusted.
2017-02-07 Provide default implementations for a couple of Store methodsEelco Dolstra1-7/+7
2017-01-26 exportReferencesGraph: Export more complete info in JSON formatEelco Dolstra1-0/+14
This writes info about every path in the closure in the same format as ‘nix path-info --json’. Thus it also includes NAR hashes and sizes. Example: [ { "path": "/nix/store/10h6li26i7g6z3mdpvra09yyf10mmzdr-hello-2.10", "narHash": "sha256:0ckdc4z20kkmpqdilx0wl6cricxv90lh85xpv2qljppcmz6vzcxl", "narSize": 197648, "references": [ "/nix/store/10h6li26i7g6z3mdpvra09yyf10mmzdr-hello-2.10", "/nix/store/27binbdy296qvjycdgr1535v8872vz3z-glibc-2.24" ], "closureSize": 20939776 }, { "path": "/nix/store/27binbdy296qvjycdgr1535v8872vz3z-glibc-2.24", "narHash": "sha256:1nfn3m3p98y1c0kd0brp80dn9n5mycwgrk183j17rajya0h7gax3", "narSize": 20742128, "references": [ "/nix/store/27binbdy296qvjycdgr1535v8872vz3z-glibc-2.24" ], "closureSize": 20742128 } ] Fixes #1134.
2017-01-20 nix-copy-closure: Implement in C++.Shea Levy1-1/+1
Tests fail currently because the database is not given proper hashes in the VM
2017-01-19 Merge pull request #981 from shlevy/build-remote-c++Eelco Dolstra1-0/+2
build-remote: Implement in C++
2016-12-07 Keep track of the exact build start/stop timesEelco Dolstra1-1/+3
2016-12-07 Add an option to make non-determinism non-fatalEelco Dolstra1-0/+11
That is, when build-repeat > 0, and the output of two rounds differ, then print a warning rather than fail the build. This is primarily to let Hydra check reproducibility of all packages.
2016-11-26 Revert "Get rid of unicode quotes (#1140)"Eelco Dolstra1-19/+19
This reverts commit f78126bfd6b6c8477fcdbc09b2f98772dbe9a1e7. There really is no need for such a massive change...
2016-11-25 Get rid of unicode quotes (#1140)Guillaume Maudoux1-19/+19
2016-11-10 Store::computeFSClosure(): Support a set of pathsEelco Dolstra1-3/+7
This way, callers can exploits the parallelism of computeFSClosure() when they have multiple paths that they need the (combined) closure of.

2016-11-09 copyClosure() / copyStorePath(): Expose dontCheckSigsEelco Dolstra1-2/+2
Needed by Hydra.
2016-11-09 Merge branch 'ssh-store' of https://github.com/shlevy/nixEelco Dolstra1-4/+10
2016-10-26 Restore the CachedFailure status codeEelco Dolstra1-0/+4
The removal of CachedFailure caused the value of TimedOut to change, which broke timed-out handling in Hydra (so timed-out builds would show up as "aborted" and would be retried, e.g. at http://hydra.nixos.org/build/42537427).
2016-10-21 Remove addPathToAccessorEelco Dolstra1-12/+2
2016-10-21 BinaryCacheStore: Optionally write a NAR listingEelco Dolstra1-1/+1
The store parameter "write-nar-listing=1" will cause BinaryCacheStore to write a file ‘<store-hash>.ls.xz’ for each ‘<store-hash>.narinfo’ added to the binary cache. This file contains an XZ-compressed JSON file describing the contents of the NAR, excluding the contents of regular files. E.g. { "version": 1, "root": { "type": "directory", "entries": { "lib": { "type": "directory", "entries": { "Mcrt1.o": { "type": "regular", "size": 1288 }, "Scrt1.o": { "type": "regular", "size": 3920 }, } } } ... } } (The actual file has no indentation.) This is intended to speed up the NixOS channels programs index generator [1], since fetching gazillions of large NARs from cache.nixos.org is currently a bottleneck for updating the regular (non-small) channel.

2016-10-07 Implement generic Store::queryValidPaths()Eelco Dolstra1-1/+1
2016-10-07 Add copyClosure utility function for HydraEelco Dolstra1-0/+5
2016-10-07 importPaths(): Fix accessor support for HydraEelco Dolstra1-0/+11
2016-09-16 Make computeFSClosure() single-threaded againEelco Dolstra1-1/+8
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.)

2016-08-10 Mark content-addressed paths in the Nix database and in .narinfoEelco Dolstra1-18/+55
This allows such paths to be imported without signatures.
2016-08-10 Add a "root" parameter to local storesEelco Dolstra1-0/+2
This makes it easier to create a diverted store, i.e. NIX_REMOTE="local?root=/tmp/root" instead of NIX_REMOTE="local?real=/tmp/root/nix/store&state=/tmp/root/nix/var/nix" NIX_LOG_DIR=/tmp/root/nix/var/log
2016-07-26 makeFixedOutputPath(): Drop superfluous HashType argumentEelco Dolstra1-1/+1
2016-06-03 Support sandbox builds by non-root usersEelco Dolstra1-0/+5
This allows an unprivileged user to perform builds on a diverted store (i.e. where the physical store location differs from the logical location). Example: $ NIX_LOG_DIR=/tmp/log NIX_REMOTE="local?real=/tmp/store&state=/tmp/var" nix-build -E \ 'with import <nixpkgs> {}; runCommand "foo" { buildInputs = [procps nettools]; } "id; ps; ifconfig; echo $out > $out"' will do a build in the Nix store physically in /tmp/store but logically in /nix/store (and thus using substituters for the latter).
2016-06-02 Make derivationFromPath work on diverted storesEelco Dolstra1-0/+2
2016-06-02 Allow setting the state directory as a store parameterEelco Dolstra1-6/+8
E.g. "local?store=/tmp/store&state=/tmp/var".
2016-06-01 Make the store directory a member variable of StoreEelco Dolstra1-62/+71
2016-05-31 nix-copy-closure / build-remote.pl: Disable signature checkingEelco Dolstra1-3/+3
This restores the Nix 1.11 behaviour.
2016-05-30 Re-implement the WantMassQuery property of binary cachesEelco Dolstra1-0/+2

2016-05-04 Add a Store::addToStore() variant that accepts a NAREelco Dolstra1-16/+18
As a side effect, this ensures that signatures are propagated when copying paths between stores. Also refactored import/export to make use of this.
