2017-11-01fetchMercurial: Don't fetch hashes we already haveEelco Dolstra
2017-10-30builtins.fetchgit: Support importing a working treeEelco Dolstra
For example, you can write src = fetchgit ./.; and if ./. refers to an unclean working tree, that tree will be copied to the Nix store. This removes the need for "cleanSource".
2017-10-25Pass lists/attrsets to bash as (associative) arraysEelco Dolstra
2017-09-08ThreadPool: On exception, interrupt the other worker threadsEelco Dolstra

2017-08-18Remove unused decodeOctalEscapedAndy Wingo
Besides being unused, this function has a bug that it will incorrectly decode the path component Ubuntu\04016.04.2\040LTS\040amd64 as "Ubuntu.04.2 LTS amd64" instead of "Ubuntu 16.04.2 LTS amd64".

Issue #1506.

2017-04-25nix repl: Use $XDG_DATA_HOME for the readline historyEelco Dolstra
2017-04-21add helper function to set 'interruptThrown'David McFarland
this fixes a linker failure on cygwin 64 due to some bad interaction between tls and shared libraries. see: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64697
2017-04-20Read per-user settings from ~/.config/nix/nix.confEelco Dolstra
2017-03-21Move istringstream_nocopy to a separate fileEelco Dolstra
2017-03-20Merge branch 'darwin-s3-binary-cache-store' of https://github.com/shlevy/nixEelco Dolstra
2017-03-16Remove "killing process <pid>" messagesEelco Dolstra
They convey no useful information.
2017-03-15runProgram(): Distinguish between empty input and no inputEelco Dolstra
For example, if we call brotli with an empty input, it shouldn't read from the caller's stdin.
2017-03-08Add missing header <sstream>Adrien Devresse
2017-03-06istringstream_nocopy: Implement in a standards-compliant way.Shea Levy
Fixes the problem mentioned in e6a61b8da788efbbbb0eb690c49434b6b5fc9741 See #1135
2017-02-16Support netrc in <nix/fetchurl.nix>Eelco Dolstra
This allows <nix/fetchurl.nix> to fetch private Git/Mercurial repositories, e.g. import <nix/fetchurl.nix> { url = https://edolstra@bitbucket.org/edolstra/my-private-repo/get/80a14018daed.tar.bz2; sha256 = "1mgqzn7biqkq3hf2697b0jc4wabkqhmzq2srdymjfa6sb9zb6qs7"; } where /etc/nix/netrc contains: machine bitbucket.org login edolstra password blabla... This works even when sandboxing is enabled. To do: add unpacking support (i.e. fetchzip functionality).
2017-02-01Restore default signal handling in child processesEelco Dolstra
In particular, this fixes Ctrl-C in nix-shell sessions.
2017-01-26Fix interrupt handlingEelco Dolstra
2017-01-19Merge pull request #981 from shlevy/build-remote-c++Eelco Dolstra
build-remote: Implement in C++
2017-01-19Kill builds when we get EOF on the log FDEelco Dolstra
This closes a long-time bug that allowed builds to hang Nix indefinitely (regardless of timeouts) simply by doing exec > /dev/null 2>&1; while true; do true; done Now, on EOF, we just send SIGKILL to the child to make sure it's really gone.
2017-01-19CleanupEelco Dolstra
2017-01-17Handle SIGINT etc. via a sigwait() signal handler threadEelco Dolstra
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.
2017-01-16AutoCloseDir: Use std::unique_ptrEelco Dolstra
2017-01-16AutoDeleteArray -> std::unique_ptrEelco Dolstra
Also, switch to C++14 for std::make_unique.
2016-12-08Fix S3BinaryCacheStoreEelco Dolstra
It failed with AWS error uploading ‘6gaxphsyhg66mz0a00qghf9nqf7majs2.ls.xz’: Unable to parse ExceptionName: MissingContentLength Message: You must provide the Content-Length HTTP header. possibly because the istringstream_nocopy introduced in 0d2ebb4373e509521f27a6e8f16bfd39d05b2188 doesn't supply the seek method that the AWS library expects. So bring back the old version, but only for S3BinaryCacheStore.
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...

This cuts hydra-queue-runner's peak memory usage by about a third.

2016-09-20nix-shell: Fix $PATH handling in the impure caseEelco Dolstra
We were passing "p=$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.
2016-09-16Make 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.)
2016-09-16printMsg(): Don't check for interruptsEelco Dolstra
Having the logger function potentially throw exceptions is Heisenbuggy.

2016-04-29Support Git repos in the Nix pathEelco Dolstra
E.g. $ nix-build -I nixpkgs=git://github.com/NixOS/nixpkgs '<nixpkgs>' -A hello This is not extremely useful yet because you can't specify a branch/revision.
2016-04-25Improved logging abstractionEelco Dolstra
This also gets rid of --log-type, since the nested log type isn't useful in a multi-threaded situation, and nobody cares about the "pretty" log type.
2016-04-20Cache path info lookups in SQLiteEelco Dolstra
This re-implements the binary cache database in C++, allowing it to be used by other Store backends, in particular the S3 backend.
2016-03-29Improve SIGINT handling in multi-threaded programsEelco Dolstra
The flag remembering whether an Interrupted exception was thrown is now thread-local. Thus, all threads will (eventually) throw Interrupted. Previously, one thread would throw Interrupted, and then the other threads wouldn't see that they were supposed to quit.
