2019-02-25downloadCached: Return ETagEelco Dolstra
This allows fetchFlake() to return the Git revision of a GitHub archive.
2018-08-06Fix Brotli decompression in 'nix log'Eelco Dolstra
This didn't work anymore since decompression was only done in the non-coroutine case. Decompressors are now sinks, just like compressors. Also fixed a bug in bzip2 API handling (we have to handle BZ_RUN_OK rather than BZ_OK), which we didn't notice because there was a missing 'throw': if (ret != BZ_OK) CompressionError("error while compressing bzip2 file");
2018-08-06Fix reporting of HTTP body size when a result callback is usedEelco Dolstra
2018-06-05Further improve upload messagesEelco Dolstra
2018-05-30Make HttpBinaryCacheStore::narFromPath() run in constant memoryEelco 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.

2018-01-26HttpBinaryCacheStore: 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
2017-09-18Don't remove Content-Encoding in fetchurl / nix-prefetch-urlEelco Dolstra
Fixes #1568.
2017-08-25Allow activities to be nestedEelco Dolstra
In particular, this allows more relevant activities ("substituting X") to supersede inferior ones ("downloading X").

2017-04-10Default to 5 download retriesDan Peebles
This should help certain downloaders that don't request anything special for the number of retries, like nix-channel.
2017-03-15S3BinaryCacheStore: Support compression of narinfo and log filesEelco Dolstra
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.
2017-02-14Add support for s3:// URIsEelco Dolstra
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.
2016-11-26Revert "Get rid of unicode quotes (#1140)"Eelco Dolstra
This reverts commit f78126bfd6b6c8477fcdbc09b2f98772dbe9a1e7. There really is no need for such a massive change...
2016-11-25Get rid of unicode quotes (#1140)Guillaume Maudoux
2016-09-16Make computeFSClosure() single-threaded againEelco 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.)
2016-09-14Enable HTTP/2 supportEelco 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.

2016-08-15builtins.fetch{url,tarball}: Allow name attributeShea Levy
2016-08-11nix-channel: implement in c++Shea Levy
2016-08-10HttpBinaryCacheStore: Retry on transient HTTP errorsEelco Dolstra
This makes us more robust against 500 errors from CloudFront or S3 (assuming the 500 error isn't cached by CloudFront...).
2016-07-26builtins.{fetchurl,fetchTarball}: Support a sha256 attributeEelco Dolstra
Also, allow builtins.{fetchurl,fetchTarball} in restricted mode if a hash is specified.
2016-04-15BinaryCacheStore::readFile(): Return a shared_ptr to a stringEelco Dolstra
This allows readFile() to indicate that a file doesn't exist, and might eliminate some large string copying.
2016-02-29Add an HTTP binary cache storeEelco Dolstra
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
2016-02-04StoreAPI -> StoreEelco Dolstra
Calling a class an API is a bit redundant...
2016-02-04Eliminate the "store" global variableEelco Dolstra
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.)
2015-10-21Show progress indicator for builtin fetchurlEelco Dolstra
2015-10-21Disable TLS verification for builtin fetchurlEelco Dolstra
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.
2015-07-20Make <nix/fetchurl.nix> a builtin builderEelco Dolstra
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.
