2017-03-15	S3BinaryCacheStore: Set Content-Type	Eelco Dolstra	1	-1/+3
	This is necessary for serving log files to browsers.
2016-11-26	Revert "Get rid of unicode quotes (#1140)"	Eelco Dolstra	1	-1/+1
	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	-1/+1

2016-10-19	Shut up clang warning	Eelco Dolstra	1	-1/+1

2016-09-20	Fix "Promise already satisfied" error	Eelco Dolstra	1	-1/+3

2016-09-16	Make computeFSClosure() single-threaded again	Eelco Dolstra	1	-8/+17
	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.)
2016-09-14	Enable HTTP/2 support	Eelco Dolstra	1	-17/+9
	The binary cache store can now use HTTP/2 to do lookups. This is much more efficient than HTTP/1.1 due to multiplexing: we can issue many requests in parallel over a single TCP connection. Thus it's no longer necessary to use a bunch of concurrent TCP connections (25 by default). For example, downloading 802 .narinfo files from https://cache.nixos.org/, using a single TCP connection, takes 11.8s with HTTP/1.1, but only 0.61s with HTTP/2. This did require a fairly substantial rewrite of the Downloader class to use the curl multi interface, because otherwise curl wouldn't be able to do multiplexing for us. As a bonus, we get connection reuse even with HTTP/1.1. All downloads are now handled by a single worker thread. Clients call Downloader::enqueueDownload() to tell the worker thread to start the download, getting a std::future to the result.
2016-08-30	Increase the sleep time between download retries	Eelco Dolstra	1	-1/+2

2016-08-10	HttpBinaryCacheStore: Retry on transient HTTP errors	Eelco Dolstra	1	-0/+2
	This makes us more robust against 500 errors from CloudFront or S3 (assuming the 500 error isn't cached by CloudFront...).
2016-06-01	HttpBinaryCacheStore: Fix caching of WantMassQuery	Eelco Dolstra	1	-2/+4
	Also, test HttpBinaryCacheStore in addition to LocalBinaryCacheStore.
2016-06-01	Make the store directory a member variable of Store	Eelco Dolstra	1	-3/+3

2016-05-30	Re-implement the WantMassQuery property of binary caches	Eelco Dolstra	1	-3/+8

2016-05-30	BinaryCacheStore: Remove buildPaths() / ensurePath()	Eelco Dolstra	1	-4/+3

2016-04-29	BinaryCacheStore: Make the signing key a parameter	Eelco Dolstra	1	-4/+3

2016-04-29	Allow parameters in store URIs	Eelco Dolstra	1	-1/+4
	This is to allow store-specific configuration, e.g. s3://my-cache?compression=bzip2&secret-key=/path/to/key.
2016-04-20	Cache path info lookups in SQLite	Eelco Dolstra	1	-2/+13
	This re-implements the binary cache database in C++, allowing it to be used by other Store backends, in particular the S3 backend.
2016-04-15	BinaryCacheStore::readFile(): Return a shared_ptr to a string	Eelco Dolstra	1	-2/+8
	This allows readFile() to indicate that a file doesn't exist, and might eliminate some large string copying.
2016-03-30	HttpBinaryCacheStore: Treat 403 errors as 404	Eelco Dolstra	1	-1/+3

2016-03-24	HttpBinaryCacheStore: Make thread-safe	Eelco Dolstra	1	-2/+6

2016-03-15	Fix Darwin build	Eelco Dolstra	1	-1/+1
	http://hydra.nixos.org/build/33279996
2016-03-04	Add option binary-cache-secret-key-file for signing binary caches	Eelco Dolstra	1	-1/+2

2016-03-04	BinaryCacheStore: Remove publicKeyFile argument	Eelco Dolstra	1	-4/+3
	The public key can be derived from the secret key, so there's no need for the user to supply it separately.
2016-03-03	Add file missing from 201b48de60751979835037a4b4f78128ba3fb7b3	Eelco Dolstra	1	-0/+76
