2017-07-03Replace a few bool flags with enumsEelco Dolstra
Functions like copyClosure() had 3 bool arguments, which creates a severe risk of mixing up arguments. Also, implement copyClosure() using copyPaths().
2017-05-02build-remote: Fix fallback to other machines when connecting failsEelco Dolstra
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.
2017-04-26Add Store nesting to fix import-from-derivation within filterSourceShea Levy
2017-04-20Read per-user settings from ~/.config/nix/nix.confEelco Dolstra
2017-04-13Convert Settings to the new config systemEelco Dolstra
This makes all config options self-documenting. Unknown or unparseable config settings and --option flags now cause a warning.
2017-04-13Add a Config class to simplify adding configuration settingsEelco Dolstra
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.
2017-04-06Implement 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.
2017-03-16copyPaths(): Use queryValidPaths() to reduce SSH latencyEelco Dolstra
2017-03-03Cache connection failuresEelco Dolstra
2017-03-03Improve SSH handlingEelco Dolstra
* 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.
2017-03-01RemoteStore::addToStore(): Send NAR rather than string containing NAREelco Dolstra
This allows the NAR to be streamed in the future (though we're not doing that yet).
2017-03-01Handle importing NARs containing files greater than 4 GiBEelco Dolstra
Also templatize readInt() to work for various integer types.
2017-02-22RemoteStore::addToStore(): Pass content-addressability assertionEelco Dolstra
... 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
2017-02-07Add a LegacySSHStore that uses nix-store --serveEelco Dolstra
This is useful for nix-copy-closure.
2017-01-16AutoDeleteArray -> std::unique_ptrEelco Dolstra
Also, switch to C++14 for std::make_unique.
2016-11-26Revert "Get rid of unicode quotes (#1140)"Eelco Dolstra
This reverts commit f78126bfd6b6c8477fcdbc09b2f98772dbe9a1e7. There really is no need for such a massive change...
2016-11-25Get rid of unicode quotes (#1140)Guillaume Maudoux
2016-11-09Merge branch 'ssh-store' of https://github.com/shlevy/nixEelco Dolstra
2016-11-09Implement backwards-compatible RemoteStore::addToStore()Eelco Dolstra
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.
2016-10-21Remove addPathToAccessorEelco Dolstra
2016-10-21BinaryCacheStore: Optionally write a NAR listingEelco Dolstra
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.

2016-09-21printMsg(lvlError, ...) -> printError(...) etc.Eelco Dolstra
2016-09-21Some notational convenience for formatting stringsEelco Dolstra
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);
2016-09-16Make computeFSClosure() single-threaded againEelco Dolstra
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.)
2016-09-02Implement nar-based addToStore for remote-storeShea Levy
2016-09-02Factor out the unix domain socket-specific code from RemoteStoreShea Levy
2016-08-10Mark content-addressed paths in the Nix database and in .narinfoEelco Dolstra
This allows such paths to be imported without signatures.
2016-08-10RemoteStore / nix-daemon: Drop support for Nix < 1.0Eelco Dolstra
2016-07-11Modernize AutoCloseFDShea Levy
2016-06-09Use O_CLOEXEC in most placesEelco Dolstra
2016-06-01Make the store directory a member variable of StoreEelco Dolstra
2016-05-31nix-copy-closure / build-remote.pl: Disable signature checkingEelco Dolstra
This restores the Nix 1.11 behaviour.
2016-05-04Do compression in a sinkEelco 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.
2016-05-04Remove OpenSSL-based signingEelco Dolstra
2016-04-29Allow parameters in store URIsEelco Dolstra
This is to allow store-specific configuration, e.g. s3://my-cache?compression=bzip2&secret-key=/path/to/key.
2016-04-25Show the log tail when a build failsEelco Dolstra
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.
2016-04-25Remove --print-build-traceEelco Dolstra
This was added to support Hydra, but Hydra no longer uses it.
2016-04-25Improved logging abstractionEelco Dolstra
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.
2016-04-20RemoteStore: Propagate InvalidPath exceptions from the daemonEelco Dolstra
2016-04-20Cache path info lookups in SQLiteEelco Dolstra
This re-implements the binary cache database in C++, allowing it to be used by other Store backends, in particular the S3 backend.
2016-04-19Move 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().
2016-04-08Remove failed build cachingEelco Dolstra
This feature was implemented for Hydra, but Hydra no longer uses it.
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.
2016-03-23Drop support for daemon socket path >= 108 charactersEelco Dolstra
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.
2016-03-22Don't overload dumpPath()Eelco Dolstra
2016-03-21Add Store::dumpPath() methodEelco Dolstra
This allows applying nix-store --verify-path to binary cache stores: NIX_REMOTE=https://cache.nixos.org nix-store --verify-path /nix/store/s5c7...
2016-02-26importPaths(): Optionally add NARs to binary cache accessorEelco Dolstra
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.
2016-02-24Eliminate reserveSpace flagEelco Dolstra
