2017-05-16	Improve progress indicator	Eelco Dolstra	1	-1/+0

2017-04-10	Default to 5 download retries	Dan Peebles	1	-1/+1
	This should help certain downloaders that don't request anything special for the number of retries, like nix-channel.
2017-03-15	S3BinaryCacheStore: Support compression of narinfo and log files	Eelco Dolstra	1	-0/+3
	You can now set the store parameter "text-compression=br" to compress textual files in the binary cache (i.e. narinfo and logs) using Brotli. This sets the Content-Encoding header; the extension of compressed files is unchanged. You can separately specify the compression of log files using "log-compression=br". This is useful when you don't want to compress narinfo files for backward compatibility.
2017-02-14	Add support for s3:// URIs	Eelco Dolstra	1	-1/+1
	This adds support for s3:// URIs in all places where Nix allows URIs, e.g. in builtins.fetchurl, builtins.fetchTarball, <nix/fetchurl.nix> and NIX_PATH. It allows fetching resources from private S3 buckets, using credentials obtained from the standard places (i.e. AWS_* environment variables, ~/.aws/credentials and the EC2 metadata server). This may not be super-useful in general, but since we already depend on aws-sdk-cpp, it's a cheap feature to add.
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

2016-09-16	Make computeFSClosure() single-threaded again	Eelco Dolstra	1	-4/+6
	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	-7/+28
	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.
2016-08-31	download.hh: Fix conflicts from nix-channel-c++ merge	Shea Levy	1	-6/+1

2016-08-31	Merge branch 'nix-channel-c++'	Shea Levy	1	-0/+6

2016-08-30	Increase the sleep time between download retries	Eelco Dolstra	1	-0/+1

2016-08-15	builtins.fetch{url,tarball}: Allow name attribute	Shea Levy	1	-1/+1

2016-08-11	nix-channel: implement in c++	Shea Levy	1	-0/+6

2016-08-10	HttpBinaryCacheStore: Retry on transient HTTP errors	Eelco Dolstra	1	-5/+6
	This makes us more robust against 500 errors from CloudFront or S3 (assuming the 500 error isn't cached by CloudFront...).
2016-07-26	builtins.{fetchurl,fetchTarball}: Support a sha256 attribute	Eelco Dolstra	1	-1/+3
	Also, allow builtins.{fetchurl,fetchTarball} in restricted mode if a hash is specified.
2016-04-15	BinaryCacheStore::readFile(): Return a shared_ptr to a string	Eelco Dolstra	1	-1/+2
	This allows readFile() to indicate that a file doesn't exist, and might eliminate some large string copying.
2016-02-29	Add an HTTP binary cache store	Eelco Dolstra	1	-4/+19
	Allowing stuff like NIX_REMOTE=https://cache.nixos.org nix-store -qR /nix/store/x1p1gl3a4kkz5ci0nfbayjqlqmczp1kq-geeqie-1.1 or NIX_REMOTE=https://cache.nixos.org nix-store --export /nix/store/x1p1gl3a4kkz5ci0nfbayjqlqmczp1kq-geeqie-1.1 \| nix-store --import
2016-02-04	StoreAPI -> Store	Eelco Dolstra	1	-2/+2
	Calling a class an API is a bit redundant...
2016-02-04	Eliminate the "store" global variable	Eelco Dolstra	1	-1/+4
	Also, move a few free-standing functions into StoreAPI and Derivation. Also, introduce a non-nullable smart pointer, ref<T>, which is just a wrapper around std::shared_ptr ensuring that the pointer is never null. (For reference-counted values, this is better than passing a "T&", because the latter doesn't maintain the refcount. Usually, the caller will have a shared_ptr keeping the value alive, but that's not always the case, e.g., when passing a reference to a std::thread via std::bind.)
2015-10-21	Show progress indicator for builtin fetchurl	Eelco Dolstra	1	-0/+1

2015-10-21	Disable TLS verification for builtin fetchurl	Eelco Dolstra	1	-1/+7
	This makes it consistent with the Nixpkgs fetchurl and makes it work in chroots. We don't need verification because the hash of the result is checked anyway.
2015-07-20	Make <nix/fetchurl.nix> a builtin builder	Eelco Dolstra	1	-0/+22
	This ensures that 1) the derivation doesn't change when Nix changes; 2) the derivation closure doesn't contain Nix and its dependencies; 3) we don't have to rely on ugly chroot hacks.
