2017-02-07	Cleanup	Eelco Dolstra

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.

2016-10-07	Implement generic Store::queryValidPaths()	Eelco Dolstra

2016-10-07	importPaths(): Fix accessor support for Hydra	Eelco Dolstra

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

2016-05-31	Shut up some clang warnings	Eelco Dolstra

2016-05-31	nix-copy-closure / build-remote.pl: Disable signature checking	Eelco Dolstra
	This restores the Nix 1.11 behaviour.
2016-05-30	Re-implement the WantMassQuery property of binary caches	Eelco Dolstra

2016-05-30	BinaryCacheStore: Remove buildPaths() / ensurePath()	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	BinaryCacheStore: Support "none" compression method	Eelco Dolstra

2016-04-29	BinaryCacheStore: Make the signing key a parameter	Eelco Dolstra

2016-04-29	BinaryCacheStore::queryPathInfo: Don't check signatures	Eelco Dolstra
	Other stores don't do this either. It's up to the caller to check signatures.
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().
2016-04-15	Make the .narinfo cache bigger	Eelco Dolstra

2016-04-15	BinaryCacheStore: Do negative caching of .narinfo lookups	Eelco Dolstra

2016-04-15	BinaryCacheStore::readFile(): Return a shared_ptr to a string	Eelco Dolstra
	This allows readFile() to indicate that a file doesn't exist, and might eliminate some large string copying.
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
2016-03-22	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...
2016-03-04	BinaryCacheStore: Remove publicKeyFile argument	Eelco Dolstra
	The public key can be derived from the secret key, so there's no need for the user to supply it separately.
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.
2016-02-25	Add NAR / Store accessor abstraction	Eelco Dolstra
	This is primary to allow hydra-queue-runner to extract files like "nix-support/hydra-build-products" from NARs in binary caches.
2016-02-24	BinaryCacheStore: Implement addToStore()	Eelco Dolstra
	So now you can do $ NIX_REMOTE=file:///tmp/binary-cache nix-instantiate '<nixpkgs>' -A hello and lots of other operations.
2016-02-24	Show a proper error message for unimplemented binary cache operations	Eelco Dolstra

2016-02-24	Move BinaryCacheStore / LocalBinaryCacheStore from Hydra	Eelco Dolstra
	So you can now do: $ NIX_REMOTE=file:///tmp/binary-cache nix-store -qR /nix/store/...
