2017-04-19 Reimplement connect-timeoutEelco Dolstra1-0/+2
Fixes #1339.
2017-04-14 Shut up some warningsEelco Dolstra1-1/+1
2017-04-13 Convert Settings to the new config systemEelco Dolstra1-1/+1
This makes all config options self-documenting. Unknown or unparseable config settings and --option flags now cause a warning.
2017-04-13 Merge branch 'rework-options' of https://github.com/copumpkin/nixEelco Dolstra1-3/+3
2017-04-10 Add CURLE_WRITE_ERROR as a transient error conditionDan Peebles1-0/+5
We've observed it failing downloads in the wild and retrying the same URL a few moments later seemed to fix it.
2017-04-06 Retry downloads on transient SSL errors tooDan Peebles1-0/+2
2017-03-31 Retry curl error 16Eelco Dolstra1-0/+1
2017-03-15 runProgram(): Distinguish between empty input and no inputEelco Dolstra1-1/+1
For example, if we call brotli with an empty input, it shouldn't read from the caller's stdin.
2017-03-15 S3BinaryCacheStore: Support compression of narinfo and log filesEelco Dolstra1-5/+11
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.
2017-03-15 Add support for brotli compressionEelco Dolstra1-2/+19
Build logs on cache.nixos.org are compressed using Brotli (since this allows them to be decompressed automatically by Chrome and Firefox), so it's handy if "nix log" can decompress them.

2017-02-27 Retry downloads on HTTP/2 stream errorsEelco Dolstra1-1/+3
Issue #1254.
2017-02-22 Explicitly model all settings and fail on unrecognized onesDan Peebles1-3/+3
Previously, the Settings class allowed other code to query for string properties, which led to a proliferation of code all over the place making up new options without any sort of central registry of valid options. This commit pulls all those options back into the central Settings class and removes the public get() methods, to discourage future abuses like that. Furthermore, because we know the full set of options ahead of time, we now fail loudly if someone enters an unrecognized option, thus preventing subtle typos. With some template fun, we could probably also dump the full set of options (with documentation, defaults, etc.) to the command line, but I'm not doing that yet here.
2017-02-22 RemoteStore::addToStore(): Pass content-addressability assertionEelco Dolstra1-0/+1
... and use this in Downloader::downloadCached(). This fixes $ nix-build https://nixos.org/channels/nixos-16.09-small/nixexprs.tar.xz -A hello error: cannot import path ‘/nix/store/csfbp1s60dkgmk9f8g0zk0mwb7hzgabd-nixexprs.tar.xz’ because it lacks a valid signature
2017-02-21 Handle CURLE_RECV_ERROR as a transient errorEelco Dolstra1-1/+1
This fixes unable to download ‘https://cache.nixos.org/nar/077h8ji74y9b0qx7rjk71xd80vjqp6q5gy137r553jlvdlxdcdlk.nar.xz’: HTTP error 200 (curl error: Failure when receiving data from the peer)

2017-02-16 Move netrcFile to SettingsEelco Dolstra1-5/+2
Also get rid of Settings::processEnvironment(), it appears to be useless.
2017-02-16 Include "curl" in the User-Agent headerEelco Dolstra1-1/+1
Some sites (e.g. BitBucket) give a helpful 401 error when trying to download a private archive if the User-Agent contains "curl", but give a redirect to a login page otherwise (so for instance "nix-prefetch-url" will succeed but produce useless output).
2017-02-16 Merge pull request #1215 from k0001/netrc-1Eelco Dolstra1-0/+8
Add netrc-file support
2017-02-14 Add support for s3:// URIsEelco Dolstra1-1/+27
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.

2017-01-26 On HTTP errors, also show the curl errorEelco Dolstra1-1/+1
This is a hopefully temporary measure to diagnose the intermittent "HTTP error 200" failures.
2017-01-24 Enable verbose curl outputEelco Dolstra1-1/+14
Closes #1182.
2017-01-17 Handle SIGINT etc. via a sigwait() signal handler threadEelco Dolstra1-5/+15
This allows other threads to install callbacks that run in a regular, non-signal context. In particular, we can use this to signal the downloader thread to quit. Closes #1183.
2016-11-26 Revert "Get rid of unicode quotes (#1140)"Eelco Dolstra1-10/+10
This reverts commit f78126bfd6b6c8477fcdbc09b2f98772dbe9a1e7. There really is no need for such a massive change...

2016-10-21 BinaryCacheStore: Optionally write a NAR listingEelco Dolstra1-1/+1
The store parameter "write-nar-listing=1" will cause BinaryCacheStore to write a file ‘<store-hash>.ls.xz’ for each ‘<store-hash>.narinfo’ added to the binary cache. This file contains an XZ-compressed JSON file describing the contents of the NAR, excluding the contents of regular files. E.g. { "version": 1, "root": { "type": "directory", "entries": { "lib": { "type": "directory", "entries": { "Mcrt1.o": { "type": "regular", "size": 1288 }, "Scrt1.o": { "type": "regular", "size": 3920 }, } } } ... } } (The actual file has no indentation.) This is intended to speed up the NixOS channels programs index generator [1], since fetching gazillions of large NARs from cache.nixos.org is currently a bottleneck for updating the regular (non-small) channel.

Commit 86e8c67efc33cf756500a1dec7fd6313658f2664 broke it, because CURL_* are not actually #defines.
2016-10-13 SSL_CERT_FILE -> NIX_SSL_CERT_FILEEelco Dolstra1-1/+2
This prevents collisions with the "native" OpenSSL, in particular on OS X. Fixes #921.

2016-09-16 Make computeFSClosure() single-threaded againEelco Dolstra1-11/+27
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 Revive binary-caches-parallel-connectionsEelco Dolstra1-2/+8
It's a slight misnomer now because it actually limits *all* downloads, not just binary cache lookups. Also add a "enable-http2" option to allow disabling use of HTTP/2 (enabled by default).
2016-09-14 Enable HTTP/2 supportEelco Dolstra1-171/+379
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.
