2018-05-30Make LocalBinaryCacheStore::narFromPath() run in constant memoryEelco Dolstra
This reduces memory consumption of nix copy --from file://... --to ~/my-nix /nix/store/95cwv4q54dc6giaqv6q6p4r02ia2km35-blender-2.79 from 514 MiB to 18 MiB for an uncompressed binary cache, and from 192 MiB to 53 MiB for a bzipped binary cache. It may also be faster because fetching can happen concurrently with decompression/writing. Continuation of 48662d151bdf4a38670897beacea9d1bd750376a. Issue https://github.com/NixOS/nix/issues/1681.

2017-03-15S3BinaryCacheStore: Set Content-TypeEelco Dolstra
This is necessary for serving log files to browsers.
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...

2016-09-16Make 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.)
2016-06-01HttpBinaryCacheStore: Fix caching of WantMassQueryEelco Dolstra
Also, test HttpBinaryCacheStore in addition to LocalBinaryCacheStore.
2016-06-01Make the store directory a member variable of StoreEelco Dolstra
2016-05-30Test the NAR info cacheEelco Dolstra
2016-05-30BinaryCacheStore: Remove buildPaths() / ensurePath()Eelco Dolstra
2016-04-29nix verify --all: Support local binary cachesEelco Dolstra
2016-04-29BinaryCacheStore: Make the signing key a parameterEelco 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.
2016-04-15BinaryCacheStore::readFile(): Return a shared_ptr to a stringEelco Dolstra
This allows readFile() to indicate that a file doesn't exist, and might eliminate some large string copying.
2016-03-04Add option binary-cache-secret-key-file for signing binary cachesEelco Dolstra
2016-03-04BinaryCacheStore: Remove publicKeyFile argumentEelco Dolstra
The public key can be derived from the secret key, so there's no need for the user to supply it separately.
2016-03-02Provide function required by HydraEelco Dolstra
2016-03-02Eliminate local-binary-cache-store.hhEelco Dolstra
2016-03-02Make store implementations pluggableEelco Dolstra
This for instance allows hydra-queue-runner to add the S3 backend at runtime.
2016-02-24Move BinaryCacheStore / LocalBinaryCacheStore from HydraEelco Dolstra
So you can now do: $ NIX_REMOTE=file:///tmp/binary-cache nix-store -qR /nix/store/...
