2016-09-21 Some notational convenience for formatting stringsEelco Dolstra6-22/+81
We can now write throw Error("file '%s' not found", path); instead of throw Error(format("file '%s' not found") % path); and similarly printError("file '%s' not found", path); instead of printMsg(lvlError, format("file '%s' not found") % path);

2016-09-20 nix-shell: Fix $PATH handling in the impure caseEelco Dolstra3-29/+55
We were passing "p=$PATH" rather than "p=$PATH;", resulting in some invalid shell code. Also, construct a separate environment for the child rather than overwriting the parent's.
2016-09-20 nix-shell: Restore CPU affinityEelco Dolstra1-6/+10
Otherwise the shell and its children will be bound to one CPU core...

2016-09-16 Make computeFSClosure() single-threaded againEelco Dolstra16-202/+385
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.)
2016-09-16 printMsg(): Don't check for interruptsEelco Dolstra3-17/+15
Having the logger function potentially throw exceptions is Heisenbuggy.
2016-09-14 nix path-info: Add some more examplesEelco Dolstra1-1/+9
2016-09-14 Revive binary-caches-parallel-connectionsEelco Dolstra2-6/+11
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 Dolstra9-207/+430
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.

2016-09-12 Fix gc-runtime testEelco Dolstra1-1/+1
It was failing on some platforms. http://hydra.nixos.org/build/39538866
2016-09-12 Fix build on GCC 4.9Eelco Dolstra1-11/+8
GCC 4.9 doesn't like reassigning a std::stringstream. http://hydra.nixos.org/build/40371644
2016-09-12 Write "T x" instead of "auto x = T"Eelco Dolstra1-35/+32
That's just silly. Hopefully this also fixes the Debian build failure: http://hydra.nixos.org/build/40371644
2016-09-08 Fix test failureEelco Dolstra1-3/+3
2016-09-08 Don't run builds as root in the user namespaceEelco Dolstra1-16/+31
This largely reverts c68e5913c71badc89ff346d1c6948517ba720c93. Running builds as root breaks "cp -p", since when running as root, "cp -p" assumes that it can succesfully chown() files. But that's not actually the case since the user namespace doesn't provide a complete uid mapping. So it barfs with a fatal error message ("cp: failed to preserve ownership for 'foo': Invalid argument").

2016-09-08 Fix early removal of rc-file for nix-shellShea Levy1-2/+0
BASH_ENV causes all non-interactive shells called via eg. /etc/bashrc to remove the rc-file before the main shell gets to run it. Completion scripts will often do this. Fixes #976. Adapted from and fixes #1034.

2016-08-30 Fix --fallbackEelco Dolstra1-7/+10
This fixes an assertion failure in "assert(goal);" in Worker::waitForInput() after a substitution goal is cancelled by the termination of another goal. The problem was the line //worker.childTerminated(shared_from_this()); // FIXME in the SubstitutionGoal destructor. This was disabled because shared_from_this() obviously doesn't work from a destructor. So we now use a real pointer for object identity.

2016-08-30 Revert "nix.spec.in: Build from the .tar.xz file."Eelco Dolstra1-1/+1
This reverts commit f32c6ed8730628d0cf32f7e124681b1011192a73. It breaks the RPM builds because Nixpkgs's rpmBuild function only copies in the .tar.gz file.

2016-08-29 Add builtin function "partition"Eelco Dolstra7-10/+54
The implementation of "partition" in Nixpkgs is O(n^2) (because of the use of ++), and for some reason was causing stack overflows in multi-threaded evaluation (not sure why). This reduces "nix-env -qa --drv-path" runtime by 0.197s and memory usage by 298 MiB (in non-Boehm mode).
2016-08-29 nix path-info: Add --json flagEelco Dolstra7-129/+472
Also, factor out JSON generation from value-to-json.{cc,hh}, and support producing indented JSON.
2016-08-29 callFunction: Copy functors to the heapShea Levy1-4/+11
Normally it's impossible to take a reference to the function passed to callFunction, so some callers (e.g. ExprApp::eval) allocate that value on the stack. For functors, a reference to the functor itself may be kept, so we need to have it on the heap. Fixes #1045
