2019-09-03	Add some noexcepts	Eelco Dolstra
	This is to assert that callback functions should never throw (since the context in which they're called may not be able to handle the exception).
2019-09-03	Ensure that Callback is called only once	Eelco Dolstra
	Also, make Callback movable but uncopyable.
2019-07-10	HttpBinaryCacheStore: Use default number of retries for NARs	Eelco Dolstra

2019-07-10	Revert "Fix 'error 9 while decompressing xz file'"	Eelco Dolstra
	This reverts commit 78fa47a7f08a4cb6ee7061bf0bd86a40e1d6dc91.
2019-06-24	Add '--no-net' convenience flag	Eelco Dolstra
	This flag * Disables substituters. * Sets the tarball-ttl to infinity (ensuring e.g. that the flake registry and any downloaded flakes are considered current). * Disables retrying downloads and sets the connection timeout to the minimum. (So it doesn't completely disable downloads at the moment.) (cherry picked from commit 8ea842260b4fd93315d35c5ba94b1ff99ab391d8)
2019-06-24	Fix 'error 9 while decompressing xz file'	Eelco Dolstra
	Once we've started writing data to a Sink, we can't restart a download request, because then we end up writing duplicate data to the Sink. Therefore we shouldn't handle retries in Downloader but at a higher level (in particular, in copyStorePath()). Fixes #2952. (cherry picked from commit a67cf5a3585c41dd9f219a2c7aa9cf67fa69520b)
2018-09-07	If fallback is enabled, temporarily disable substituters after a failure	Eelco Dolstra
	Otherwise, we just keep asking the substituter for other .narinfo files, which can take a very long time due to retries/timeouts.
2018-06-01	Improve binary cache upload messages	Eelco Dolstra
	Don't say "download" when we mean "upload".
2018-05-30	Make HttpBinaryCacheStore::narFromPath() run in constant memory	Eelco Dolstra
	This reduces memory consumption of nix copy --from https://cache.nixos.org --to ~/my-nix /nix/store/95cwv4q54dc6giaqv6q6p4r02ia2km35-blender-2.79 from 176 MiB to 82 MiB. (The remaining memory is probably due to xz decompression overhead.) Issue https://github.com/NixOS/nix/issues/1681. Issue https://github.com/NixOS/nix/issues/1969.
2018-05-30	Simplify the callback mechanism	Eelco Dolstra

2018-01-31	Cleanup	Eelco Dolstra

2018-01-26	HttpBinaryCacheStore: Support upsertFile with PUT.	Shea Levy
	Some servers, such as Artifactory, allow uploading with PUT and BASIC auth. This allows nix copy to work to upload binaries to those servers. Worked on together with @adelbertc
2017-07-30	Replace Unicode quotes in user-facing strings by ASCII	Jörg Thalheim
	Relevant RFC: NixOS/rfcs#4 $ ag -l \| xargs sed -i -e "/\"/s/’/'/g;/\"/s/‘/'/g"
2017-05-16	Improve progress indicator	Eelco Dolstra

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

2016-10-19	Shut up clang warning	Eelco Dolstra

2016-09-20	Fix "Promise already satisfied" error	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.)
2016-09-14	Enable HTTP/2 support	Eelco Dolstra
	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

2016-08-10	HttpBinaryCacheStore: Retry on transient HTTP errors	Eelco Dolstra
	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
	Also, test HttpBinaryCacheStore in addition to LocalBinaryCacheStore.
2016-06-01	Make the store directory a member variable of Store	Eelco Dolstra

2016-05-30	Re-implement the WantMassQuery property of binary caches	Eelco Dolstra

2016-05-30	BinaryCacheStore: Remove buildPaths() / ensurePath()	Eelco Dolstra

2016-04-29	BinaryCacheStore: Make the signing key a parameter	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.
2016-04-20	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.
2016-04-15	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.
2016-03-30	HttpBinaryCacheStore: Treat 403 errors as 404	Eelco Dolstra

2016-03-24	HttpBinaryCacheStore: Make thread-safe	Eelco Dolstra

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

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.
2016-03-03	Add file missing from 201b48de60751979835037a4b4f78128ba3fb7b3	Eelco Dolstra
