2022-05-30	HttpBinaryCacheStore::getFile(): Don't throw an exception	Eelco Dolstra
	This violates the noexcept specification. Fixes #6445.
2022-01-18	Get rid of std::shared_ptr<std::string> and ref<std::string>	Eelco Dolstra
	These were needed back in the pre-C++11 era because we didn't have move semantics. But now we do.
2021-09-22	Make setDefault() typed	Eelco Dolstra

2020-12-20	Overhaul store subclassing	John Ericson
	We embrace virtual the rest of the way, and get rid of the `assert(false)` 0-param constructors. We also list config base classes first, so the constructor order is always: 1. all the configs 2. all the stores Each in the same order
2020-10-06	Remove static variable name clashes	Eelco Dolstra
	This was useful for an experiment with building Nix as a single compilation unit. It's not very useful otherwise but also doesn't hurt...
2020-10-05	Fix s3:// store	Eelco Dolstra
	Fixes https://github.com/NixOS/nixos-org-configurations/issues/123.
2020-09-21	Move Callback into its own header	Eelco Dolstra
	This gets rid of the inclusion of <future> in util.hh, cutting compilation time by ~20s (CPU time). Issue #4045.
2020-09-16	Add a name to the stores	regnat
	So that it can be printed by `nix describe-stores`
2020-09-16	Document the new store hierarchy	regnat

2020-09-16	Properly filter the stores according to their declared uriSchemes	regnat
	When opening a store, only try the stores whose `uriSchemes()` include the current one
2020-09-16	Correctly call all the parent contructors of the stores	regnat
	Using virtual inheritance means that only the default constructors of the parent classes will be called, which isn't what we want
2020-09-16	Separate store configs from the implems	regnat
	Rework the `Store` hierarchy so that there's now one hierarchy for the store configs and one for the implementations (where each implementation extends the corresponding config). So a class hierarchy like ``` StoreConfig-------->Store \| \| v v SubStoreConfig----->SubStore \| \| v v SubSubStoreConfig-->SubSubStore ``` (with virtual inheritance to prevent DDD). The advantage of this architecture is that we can now introspect the configuration of a store without having to instantiate the store itself
2020-09-16	Separate the instantiation and initialisation of the stores	regnat
	Add a new `init()` method to the `Store` class that is supposed to handle all the effectful initialisation needed to set-up the store. The constructor should remain side-effect free and just initialize the c++ data structure. The goal behind that is that we can create “dummy” instances of each store to query static properties about it (the parameters it accepts for example)
2020-09-16	Fix the registration of stores	regnat

2020-09-16	Make the store plugins more introspectable	regnat
	Directly register the store classes rather than a function to build an instance of them. This gives the possibility to introspect static members of the class or choose different ways of instantiating them.
2020-09-01	Allow HTTP binary cache to request absolute uris	Domen Kožar

2020-07-13	Make 'nix copy' to s3:// binary caches run in constant memory	Eelco Dolstra

2020-04-08	DownloadRequest -> DataTransferRequest	Nikola Knezevic

2020-03-24	Misc changes from the flakes branch	Eelco Dolstra

2019-12-17	Add priority setting to stores	Eelco Dolstra
	This allows overriding the priority of substituters, e.g. $ nix-store --store ~/my-nix/ -r /nix/store/df3m4da96d84ljzxx4mygfshm1p0r2n3-geeqie-1.4 \ --substituters 'http://cache.nixos.org?priority=100 daemon?priority=10' Fixes #3264.
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.
