2016-11-09 Merge branch 'ssh-store' of https://github.com/shlevy/nixEelco Dolstra1-45/+70
2016-11-09 Implement backwards-compatible RemoteStore::addToStore()Eelco Dolstra1-1/+22
The SSHStore PR adds this functionality to the daemon, but we have to handle the case where the Nix daemon is 1.11. Also, don't require signatures for trusted users. This restores 1.11 behaviour. Fixes https://github.com/NixOS/hydra/issues/398.
2016-10-21 Remove addPathToAccessorEelco Dolstra1-1/+1
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.

2016-09-21 printMsg(lvlError, ...) -> printError(...) etc.Eelco Dolstra1-1/+1
2016-09-21 Some notational convenience for formatting stringsEelco Dolstra1-1/+1
We can now write throw Error("file '%s' not found", path); instead of throw Error(format("file '%s' not found") % path); and similarly printError("file '%s' not found", path); instead of printMsg(lvlError, format("file '%s' not found") % path);
2016-09-16 Make computeFSClosure() single-threaded againEelco Dolstra1-30/+34
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.)
2016-09-02 Implement nar-based addToStore for remote-storeShea Levy1-1/+6
2016-09-02 Factor out the unix domain socket-specific code from RemoteStoreShea Levy1-26/+39
2016-08-10 Mark content-addressed paths in the Nix database and in .narinfoEelco Dolstra1-0/+1
This allows such paths to be imported without signatures.
2016-08-10 RemoteStore / nix-daemon: Drop support for Nix < 1.0Eelco Dolstra1-19/+15
2016-07-11 Modernize AutoCloseFDShea Levy1-6/+6
2016-06-09 Use O_CLOEXEC in most placesEelco Dolstra1-1/+5
2016-06-01 Make the store directory a member variable of StoreEelco Dolstra1-20/+21
2016-05-31 nix-copy-closure / build-remote.pl: Disable signature checkingEelco Dolstra1-1/+2
This restores the Nix 1.11 behaviour.
2016-05-04 Do compression in a sinkEelco Dolstra1-1/+1
2016-05-04 Add a Store::addToStore() variant that accepts a NAREelco Dolstra1-19/+6
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 Remove OpenSSL-based signingEelco Dolstra1-6/+3
2016-04-29 Allow parameters in store URIsEelco Dolstra1-0/+6
This is to allow store-specific configuration, e.g. s3://my-cache?compression=bzip2&secret-key=/path/to/key.
2016-04-25 Show the log tail when a build failsEelco Dolstra1-1/+1
If --no-build-output is given (which will become the default for the "nix" command at least), show the last 10 lines of the build output if the build fails.
2016-04-25 Remove --print-build-traceEelco Dolstra1-1/+1
This was added to support Hydra, but Hydra no longer uses it.
2016-04-25 Improved logging abstractionEelco Dolstra1-6/+4
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.
2016-04-20 RemoteStore: Propagate InvalidPath exceptions from the daemonEelco Dolstra1-1/+12
2016-04-20 Cache path info lookups in SQLiteEelco Dolstra1-1/+0
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 StoreEelco Dolstra1-44/+18
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().
2016-04-08 Remove failed build cachingEelco Dolstra1-17/+1
This feature was implemented for Hydra, but Hydra no longer uses it.
2016-04-05 Add "nix copy-sigs" commandEelco Dolstra1-0/+9
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
2016-03-30 LocalStore: Keep track of ultimately trusted pathsEelco Dolstra1-0/+4
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.
2016-03-23 Drop support for daemon socket path >= 108 charactersEelco Dolstra1-15/+3
Doing a chdir() is a bad idea in multi-threaded programs, leading to failures such as error: cannot connect to daemon at ‘/nix/var/nix/daemon-socket/socket’: No such file or directory Since Linux doesn't have a connectat() syscall like FreeBSD, there is no way we can support this in a race-free way.
2016-03-22 Don't overload dumpPath()Eelco Dolstra1-1/+1
2016-03-21 Add Store::dumpPath() methodEelco Dolstra1-1/+1
This allows applying nix-store --verify-path to binary cache stores: NIX_REMOTE=https://cache.nixos.org nix-store --verify-path /nix/store/s5c7...
2016-02-26 importPaths(): Optionally add NARs to binary cache accessorEelco Dolstra1-1/+2
This enables an optimisation in hydra-queue-runner, preventing a download of a NAR it just uploaded to the cache when reading files like hydra-build-products.
2016-02-24 Eliminate reserveSpace flagEelco Dolstra1-2/+2
2016-02-24 Remove bad daemon connections from the poolEelco Dolstra1-1/+5
This is necessary for long-running processes like hydra-queue-runner: if a nix-daemon worker is killed, we need to stop reusing that connection.
2016-02-23 Pool<T>: Allow a maximum pool sizeEelco Dolstra1-15/+15
2016-02-23 RemoteStore: Make thread-safeEelco Dolstra1-226/+221
This allows a RemoteStore object to be used safely from multiple threads concurrently. It will make multiple daemon connections if necessary. Note: pool.hh and sync.hh have been copied from the Hydra source tree.
2016-02-16 Rename ValidPathInfo::hash -> narHash for consistencyEelco Dolstra1-1/+1
2016-01-31 Use the daemon when we don't have write access to the Nix databaseEelco Dolstra1-8/+2
2015-12-02 daemon: Add 'buildMode' parameter to 'buildPaths' RPCLudovic Courtès1-3/+9
2015-09-03 Implement buildDerivation() via the daemonEelco Dolstra1-1/+9
2015-07-20 More cleanupEelco Dolstra1-102/+63
2015-07-17 OCD: foreach -> C++11 ranged forEelco Dolstra1-14/+14
2015-07-17 Allow remote builds without sending the derivation closureEelco Dolstra1-0/+7
Previously, to build a derivation remotely, we had to copy the entire closure of the .drv file to the remote machine, even though we only need the top-level derivation. This is very wasteful: the closure can contain thousands of store paths, and in some Hydra use cases, include source paths that are very large (e.g. Git/Mercurial checkouts). So now there is a new operation, StoreAPI::buildDerivation(), that performs a build from an in-memory representation of a derivation (BasicDerivation) rather than from a on-disk .drv file. The only files that need to be in the Nix store are the sources of the derivation (drv.inputSrcs), and the needed output paths of the dependencies (as described by drv.inputDrvs). "nix-store --serve" exposes this interface. Note that this is a privileged operation, because you can construct a derivation that builds any store path whatsoever. Fixing this will require changing the hashing scheme (i.e., the output paths should be computed from the other fields in BasicDerivation, allowing them to be verified without access to other derivations). However, this would be quite nice because it would allow .drv-free building (e.g. "nix-env -i" wouldn't have to write any .drv files to disk). Fixes #173.
2015-06-02 Add a ‘verifyStore’ RPCLudovic Courtès1-0/+10
Hello! The patch below adds a ‘verifyStore’ RPC with the same signature as the current LocalStore::verifyStore method.
