2019-09-03	Add some noexcepts	Eelco Dolstra	1	-1/+1
	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	1	-5/+7
	Also, make Callback movable but uncopyable.
2019-07-10	HttpBinaryCacheStore: Use default number of retries for NARs	Eelco Dolstra	1	-1/+0

2019-07-10	Revert "Fix 'error 9 while decompressing xz file'"	Eelco Dolstra	1	-41/+16
	This reverts commit 78fa47a7f08a4cb6ee7061bf0bd86a40e1d6dc91.
2019-06-24	Add '--no-net' convenience flag	Eelco Dolstra	1	-1/+0
	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	1	-16/+41
	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	1	-1/+40
	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	1	-1/+1
	Don't say "download" when we mean "upload".
2018-05-30	Make HttpBinaryCacheStore::narFromPath() run in constant memory	Eelco Dolstra	1	-2/+20
	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	1	-11/+7

2018-01-31	Cleanup	Eelco Dolstra	1	-3/+4

2018-01-26	HttpBinaryCacheStore: Support upsertFile with PUT.	Shea Levy	1	-1/+7
	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	1	-1/+1
	Relevant RFC: NixOS/rfcs#4 $ ag -l \| xargs sed -i -e "/\"/s/’/'/g;/\"/s/‘/'/g"
2017-05-16	Improve progress indicator	Eelco Dolstra	1	-2/+0

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
