2017-05-02 build-remote: Fix fallback to other machines when connecting failsEelco Dolstra1-1/+7
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.
2017-04-26 Add Store nesting to fix import-from-derivation within filterSourceShea Levy1-0/+2
2017-04-20 Read per-user settings from ~/.config/nix/nix.confEelco Dolstra1-1/+1
2017-04-13 Convert Settings to the new config systemEelco Dolstra1-3/+1
This makes all config options self-documenting. Unknown or unparseable config settings and --option flags now cause a warning.
2017-04-13 Add a Config class to simplify adding configuration settingsEelco Dolstra1-1/+1
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.
2017-04-06 Implement RemoteStore::queryMissing()Eelco Dolstra1-0/+25
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.
2017-03-16 copyPaths(): Use queryValidPaths() to reduce SSH latencyEelco Dolstra1-1/+1
2017-03-03 Cache connection failuresEelco Dolstra1-1/+14
2017-03-03 Improve SSH handlingEelco Dolstra1-5/+5
* Unify SSH code in SSHStore and LegacySSHStore. * Fix a race starting the SSH master. We now wait synchronously for the SSH master to finish starting. This prevents the SSH clients from starting their own connections. * Don't use a master if max-connections == 1. * Add a "max-connections" store parameter. * Add a "compress" store parameter.
2017-03-01 RemoteStore::addToStore(): Send NAR rather than string containing NAREelco Dolstra1-2/+3
This allows the NAR to be streamed in the future (though we're not doing that yet).
2017-03-01 Handle importing NARs containing files greater than 4 GiBEelco Dolstra1-13/+11
Also templatize readInt() to work for various integer types.
2017-02-22 RemoteStore::addToStore(): Pass content-addressability assertionEelco Dolstra1-1/+1
... 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 Add a LegacySSHStore that uses nix-store --serveEelco Dolstra1-0/+1
This is useful for nix-copy-closure.
2017-01-16 AutoDeleteArray -> std::unique_ptrEelco Dolstra1-3/+2
Also, switch to C++14 for std::make_unique.
2016-11-26 Revert "Get rid of unicode quotes (#1140)"Eelco Dolstra1-3/+3
This reverts commit f78126bfd6b6c8477fcdbc09b2f98772dbe9a1e7. There really is no need for such a massive change...
2016-11-25 Get rid of unicode quotes (#1140)Guillaume Maudoux1-3/+3
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.
