2017-03-01	RemoteStore::addToStore(): Send NAR rather than string containing NAR	Eelco Dolstra
	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
	Also templatize readInt() to work for various integer types.
2017-02-22	RemoteStore::addToStore(): Pass content-addressability assertion	Eelco 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
2017-02-07	Add a LegacySSHStore that uses nix-store --serve	Eelco Dolstra
	This is useful for nix-copy-closure.
2017-01-16	AutoDeleteArray -> std::unique_ptr	Eelco Dolstra
	Also, switch to C++14 for std::make_unique.
2016-11-26	Revert "Get rid of unicode quotes (#1140)"	Eelco Dolstra
	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

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

2016-11-09	Implement 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.
2016-10-21	Remove addPathToAccessor	Eelco Dolstra

2016-10-21	BinaryCacheStore: Optionally write a NAR listing	Eelco 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.

2016-09-21	printMsg(lvlError, ...) -> printError(...) etc.	Eelco Dolstra

2016-09-21	Some notational convenience for formatting strings	Eelco 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);
2016-09-16	Make computeFSClosure() single-threaded again	Eelco 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.)
2016-09-02	Implement nar-based addToStore for remote-store	Shea Levy

2016-09-02	Factor out the unix domain socket-specific code from RemoteStore	Shea Levy

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

2016-07-11	Modernize AutoCloseFD	Shea Levy

2016-06-09	Use O_CLOEXEC in most places	Eelco Dolstra

2016-06-01	Make the store directory a member variable of Store	Eelco Dolstra

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

2016-05-04	Add a Store::addToStore() variant that accepts a NAR	Eelco 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.
2016-05-04	Remove OpenSSL-based signing	Eelco Dolstra

2016-04-29	Allow parameters in store URIs	Eelco Dolstra
	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
	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
	This was added to support Hydra, but Hydra no longer uses it.
2016-04-25	Improved logging abstraction	Eelco 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.
2016-04-20	RemoteStore: Propagate InvalidPath exceptions from the daemon	Eelco Dolstra

2016-04-20	Cache path info lookups in SQLite	Eelco Dolstra
	This re-implements the binary cache database in C++, allowing it to be used by other Store backends, in particular the S3 backend.
2016-04-19	Move path info caching from BinaryCacheStore to Store	Eelco 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().
2016-04-08	Remove failed build caching	Eelco Dolstra
	This feature was implemented for Hydra, but Hydra no longer uses it.
2016-04-05	Add "nix copy-sigs" command	Eelco 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
2016-03-30	LocalStore: Keep track of ultimately trusted paths	Eelco 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.
2016-03-23	Drop support for daemon socket path >= 108 characters	Eelco 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.
2016-03-22	Don't overload dumpPath()	Eelco Dolstra

2016-03-21	Add Store::dumpPath() method	Eelco 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...
2016-02-26	importPaths(): Optionally add NARs to binary cache accessor	Eelco 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.
2016-02-24	Eliminate reserveSpace flag	Eelco Dolstra

2016-02-24	Remove bad daemon connections from the pool	Eelco Dolstra
	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

2016-02-23	RemoteStore: Make thread-safe	Eelco Dolstra
	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 consistency	Eelco Dolstra

2016-01-31	Use the daemon when we don't have write access to the Nix database	Eelco Dolstra

2015-12-02	daemon: Add 'buildMode' parameter to 'buildPaths' RPC	Ludovic Courtès

2015-09-03	Implement buildDerivation() via the daemon	Eelco Dolstra

2015-07-20	More cleanup	Eelco Dolstra

2015-07-17	OCD: foreach -> C++11 ranged for	Eelco Dolstra

2015-07-17	Allow remote builds without sending the derivation closure	Eelco Dolstra
	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.
