2017-04-20	Read per-user settings from ~/.config/nix/nix.conf	Eelco Dolstra	1	-1/+1

2017-04-13	Convert Settings to the new config system	Eelco Dolstra	1	-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 settings	Eelco Dolstra	1	-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 Dolstra	1	-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 latency	Eelco Dolstra	1	-1/+1

2017-03-03	Cache connection failures	Eelco Dolstra	1	-1/+14

2017-03-03	Improve SSH handling	Eelco Dolstra	1	-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 NAR	Eelco Dolstra	1	-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 GiB	Eelco Dolstra	1	-13/+11
	Also templatize readInt() to work for various integer types.
2017-02-22	RemoteStore::addToStore(): Pass content-addressability assertion	Eelco Dolstra	1	-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 --serve	Eelco Dolstra	1	-0/+1
	This is useful for nix-copy-closure.
2017-01-16	AutoDeleteArray -> std::unique_ptr	Eelco Dolstra	1	-3/+2
	Also, switch to C++14 for std::make_unique.
2016-11-26	Revert "Get rid of unicode quotes (#1140)"	Eelco Dolstra	1	-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 Maudoux	1	-3/+3

2016-11-09	Merge branch 'ssh-store' of https://github.com/shlevy/nix	Eelco Dolstra	1	-45/+70

2016-11-09	Implement backwards-compatible RemoteStore::addToStore()	Eelco Dolstra	1	-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 addPathToAccessor	Eelco Dolstra	1	-1/+1

2016-10-21	BinaryCacheStore: Optionally write a NAR listing	Eelco Dolstra	1	-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 Dolstra	1	-1/+1

2016-09-21	Some notational convenience for formatting strings	Eelco Dolstra	1	-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 again	Eelco Dolstra	1	-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-store	Shea Levy	1	-1/+6

2016-09-02	Factor out the unix domain socket-specific code from RemoteStore	Shea Levy	1	-26/+39

2016-08-10	Mark content-addressed paths in the Nix database and in .narinfo	Eelco Dolstra	1	-0/+1
	This allows such paths to be imported without signatures.
2016-08-10	RemoteStore / nix-daemon: Drop support for Nix < 1.0	Eelco Dolstra	1	-19/+15

2016-07-11	Modernize AutoCloseFD	Shea Levy	1	-6/+6

2016-06-09	Use O_CLOEXEC in most places	Eelco Dolstra	1	-1/+5

2016-06-01	Make the store directory a member variable of Store	Eelco Dolstra	1	-20/+21

2016-05-31	nix-copy-closure / build-remote.pl: Disable signature checking	Eelco Dolstra	1	-1/+2
	This restores the Nix 1.11 behaviour.
2016-05-04	Do compression in a sink	Eelco Dolstra	1	-1/+1

2016-05-04	Add a Store::addToStore() variant that accepts a NAR	Eelco Dolstra	1	-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 signing	Eelco Dolstra	1	-6/+3

2016-04-29	Allow parameters in store URIs	Eelco Dolstra	1	-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 fails	Eelco Dolstra	1	-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-trace	Eelco Dolstra	1	-1/+1
	This was added to support Hydra, but Hydra no longer uses it.
2016-04-25	Improved logging abstraction	Eelco Dolstra	1	-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 daemon	Eelco Dolstra	1	-1/+12

2016-04-20	Cache path info lookups in SQLite	Eelco Dolstra	1	-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 Store	Eelco Dolstra	1	-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 caching	Eelco Dolstra	1	-17/+1
	This feature was implemented for Hydra, but Hydra no longer uses it.
2016-04-05	Add "nix copy-sigs" command	Eelco Dolstra	1	-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 paths	Eelco Dolstra	1	-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 characters	Eelco Dolstra	1	-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 Dolstra	1	-1/+1

2016-03-21	Add Store::dumpPath() method	Eelco Dolstra	1	-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 accessor	Eelco Dolstra	1	-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 flag	Eelco Dolstra	1	-2/+2

2016-02-24	Remove bad daemon connections from the pool	Eelco Dolstra	1	-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 size	Eelco Dolstra	1	-15/+15

2016-02-23	RemoteStore: Make thread-safe	Eelco Dolstra	1	-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.
