2018-05-02Fix some random -Wconversion warningsEelco Dolstra
2018-05-02Fix bzip2 compression of files > 4 GiBEelco Dolstra
Bzip2's 'avail_in' parameter is declared as an unsigned int, so assigning a size_t length to it led to silent truncation. Fixes #2111.

2018-03-21Make 'nix copy --from ssh://...' run in constant memoryEelco Dolstra
For instance, this reduced the memory consumption of $ nix copy --from ssh://localhost --to ~/my-nix /nix/store/1n7x0yv8vq6zi90hfmian84vdhd04bgp-blender-2.79a from 632 MiB to 16 MiB.

2018-03-16Reduce substitution memory consumptionEelco Dolstra
copyStorePath() now pipes the output of srcStore->narFromPath() directly into dstStore->addToStore(). The sink used by the former is converted into a source usable by the latter using boost::coroutine2. This is based on [1]. This reduces the maximum resident size of $ nix build --store ~/my-nix/ /nix/store/b0zlxla7dmy1iwc3g459rjznx59797xy-binutils-2.28.1 --substituters file:///tmp/binary-cache-xz/ --no-require-sigs from 418592 KiB to 53416 KiB. (The previous commit also reduced the runtime from ~4.2s to ~3.4s, not sure why.) A further improvement will be to download files into a Sink. [1] https://github.com/NixOS/nix/compare/master...Mathnerd314:dump-fix-coroutine#diff-dcbcac55a634031f9cc73707da6e4b18 Issue #1969.

2018-03-09Fix double free in Store::queryPathInfo()Eelco Dolstra
It was holding on to a Value* (i.e. a std::shared_ptr<ValidPathInfo>*) outside of the pathInfoCache lock, so the std::shared_ptr could be destroyed between the release of the lock and the decrement of the std::shared_ptr refcount. This can happen if more than 'path-info-cache-size' paths are added in the meantime, *or* if clearPathInfoCache() is called. The hydra-queue-runner queue monitor thread periodically calls the later, so is likely to trigger a crash. Fixes https://github.com/NixOS/hydra/issues/542.

2018-02-19libutil: Fix invalid assert on decoding base64 hashesTuomas Tynkkynen
The assertion is broken because there is no one-to-one mapping from length of a base64 string to the length of the output. E.g. "1q69lz7Empb06nzfkj651413n9icx0njmyr3xzq1j9q=" results in a 32-byte output. "1q69lz7Empb06nzfkj651413n9icx0njmyr3xzq1j9qy" results in a 33-byte output. To reproduce, evaluate: builtins.derivationStrict { name = "0"; builder = "0"; system = "0"; outputHashAlgo = "sha256"; outputHash = "1q69lz7Empb06nzfkj651413n9icx0njmyr3xzq1j9qy"; } Found by afl-fuzz.

2018-02-13Fix #1762Linus Heckemann
nix-store --export, nix-store --dump, and nix dump-path would previously fail silently if writing the data out failed, because a) FdSink::write ignored exceptions, and b) the commands relied on FdSink's destructor, which ignores exceptions, to flush the data out. This could cause rather opaque issues with installing nixos, because nix-store --export would happily proceed even if it couldn't write its data out (e.g. if nix-store --import on the other side of the pipe failed). This commit adds tests that expose these issues in the nix-store commands, and fixes them for all three.

2018-02-07Improve filtering of ANSI escape sequences in build logsEelco Dolstra
All ANSI sequences except color setting are now filtered out. In particular, terminal resets (such as from NixOS VM tests) are filtered out. Also, fix the completely broken tab character handling.

the case of hydra where the overhead of single threaded encoding is more noticeable e.g most of the time spent in "Sending inputs"/"Receiving outputs" is due to compression while the actual upload to the binary cache seems to be negligible.
2018-01-16Add pure evaluation modeEelco Dolstra
In this mode, the following restrictions apply: * The builtins currentTime, currentSystem and storePath throw an error. * $NIX_PATH and -I are ignored. * fetchGit and fetchMercurial require a revision hash. * fetchurl and fetchTarball require a sha256 attribute. * No file system access is allowed outside of the paths returned by fetch{Git,Mercurial,url,Tarball}. Thus 'nix build -f ./foo.nix' is not allowed. Thus, the evaluation result is completely reproducible from the command line arguments. E.g. nix build --pure-eval '( let nix = fetchGit { url = https://github.com/NixOS/nixpkgs.git; rev = "9c927de4b179a6dd210dd88d34bda8af4b575680"; }; nixpkgs = fetchGit { url = https://github.com/NixOS/nixpkgs.git; ref = "release-17.09"; rev = "66b4de79e3841530e6d9c6baf98702aa1f7124e4"; }; in (import (nix + "/release.nix") { inherit nix nixpkgs; }).build.x86_64-linux )' The goal is to enable completely reproducible and traceable evaluation. For example, a NixOS configuration could be fully described by a single Git commit hash. 'nixos-rebuild' would do something like nix build --pure-eval '( (import (fetchGit { url = file:///my-nixos-config; rev = "..."; })).system ') where the Git repository /my-nixos-config would use further fetchGit calls or Git externals to fetch Nixpkgs and whatever other dependencies it has. Either way, the commit hash would uniquely identify the NixOS configuration and allow it to reproduced.
2017-12-30use libbrotli directly when availableWill Dietz
* Look for both 'brotli' and 'bro' as external command, since upstream has renamed it in newer versions. If neither are found, current runtime behavior is preserved: try to find 'bro' on PATH. * Limit amount handed to BrotliEncoderCompressStream to ensure interrupts are processed in a timely manner. Testing shows negligible performance impact. (Other compression sinks don't seem to require this)

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".
2017-10-30Fix (highly unlikely) race condition in readLinkTyson Whitehead
Used to determine symlink size with stat and value with readlink. This could technically result in garbage if symlink changed between calls. Also gets around the broken stat implementation in our network filesystem (returns size + 1 giving a byte of garbage).
