2019-08-02 Add a post-build-hookregnat1-1/+22
Passing `--post-build-hook /foo/bar` to a nix-* command will cause `/foo/bar` to be executed after each build with the following environment variables set: DRV_PATH=/nix/store/drv-that-has-been-built.drv OUT_PATHS=/nix/store/...build /nix/store/...build-bin /nix/store/...build-dev This can be useful in particular to upload all the builded artifacts to the cache (including the ones that don't appear in the runtime closure of the final derivation or are built because of IFD). This new feature prints the stderr/stdout output to the `nix-build` and `nix build` client, and the output is printed in a Nix 2 compatible format: [nix]$ ./inst/bin/nix-build ./test.nix these derivations will be built: /nix/store/ishzj9ni17xq4hgrjvlyjkfvm00b0ch9-my-example-derivation.drv building '/nix/store/ishzj9ni17xq4hgrjvlyjkfvm00b0ch9-my-example-derivation.drv'... hello! bye! running post-build-hook '/home/grahamc/projects/github.com/NixOS/nix/post-hook.sh'... post-build-hook: + sleep 1 post-build-hook: + echo 'Signing paths' /nix/store/qr213vjmibrqwnyp5fw678y7whbkqyny-my-example-derivation post-build-hook: Signing paths /nix/store/qr213vjmibrqwnyp5fw678y7whbkqyny-my-example-derivation post-build-hook: + sleep 1 post-build-hook: + echo 'Uploading paths' /nix/store/qr213vjmibrqwnyp5fw678y7whbkqyny-my-example-derivation post-build-hook: Uploading paths /nix/store/qr213vjmibrqwnyp5fw678y7whbkqyny-my-example-derivation post-build-hook: + sleep 1 post-build-hook: + printf 'very important stuff' /nix/store/qr213vjmibrqwnyp5fw678y7whbkqyny-my-example-derivation [nix-shell:~/projects/github.com/NixOS/nix]$ ./inst/bin/nix build -L -f ./test.nix my-example-derivation> hello! my-example-derivation> bye! my-example-derivation (post)> + sleep 1 my-example-derivation (post)> + echo 'Signing paths' /nix/store/c263gzj2kb2609mz8wrbmh53l14wzmfs-my-example-derivation my-example-derivation (post)> Signing paths /nix/store/c263gzj2kb2609mz8wrbmh53l14wzmfs-my-example-derivation my-example-derivation (post)> + sleep 1 my-example-derivation (post)> + echo 'Uploading paths' /nix/store/c263gzj2kb2609mz8wrbmh53l14wzmfs-my-example-derivation my-example-derivation (post)> Uploading paths /nix/store/c263gzj2kb2609mz8wrbmh53l14wzmfs-my-example-derivation my-example-derivation (post)> + sleep 1 my-example-derivation (post)> + printf 'very important stuff' [1 built, 0.0 MiB DL] Co-authored-by: Graham Christensen <graham@grahamc.com> Co-authored-by: Eelco Dolstra <edolstra@gmail.com>

2019-05-03 Fix "Bad system call" running i686-linux binaries on x86_64-linuxEelco Dolstra1-0/+3
To determine which seccomp filters to install, we were incorrectly using settings.thisSystem, which doesn't denote the actual system when --system is used. Fixes #2791.
2019-03-14 experimental/optional -> optionalEelco Dolstra1-1/+1
2019-02-05 Revert "Restore parent mount namespace before executing a child process"Eelco Dolstra1-24/+0
This reverts commit a0ef21262f4d5652bfb65cfacaec01d89c475a93. This doesn't work in 'nix run' and nix-shell because setns() fails in multithreaded programs, and Boehm GC mark threads are uncancellable. Fixes #2646.
2018-12-13 probably typovolth1-1/+1

2018-11-15 Fix 'Read-only file system' when building a derivationEelco Dolstra1-1/+2
2018-11-13 Restore parent mount namespace before executing a child processEelco Dolstra1-0/+23
This ensures that they can't write to /nix/store. Fixes #2535.
2018-10-31 config: use all of XDG_CONFIG_DIRSLinus Heckemann1-0/+9
Previously, config would only be read from XDG_CONFIG_HOME. This change allows reading config from additional directories, which enables e.g. per-project binary caches or chroot stores with the help of direnv.
2018-09-13 Merge branch 'dirOf-relative' of https://github.com/lheckemann/nixEelco Dolstra1-1/+1
2018-09-04 Get effective user in Nix commandsMatthew Bauer1-1/+1
‘geteuid’ gives us the user that the command is being run as, including in setuid modes. By using geteuid to determind id, we can avoid the ‘sudo -i’ hack when upgrading Nix. So now, upgrading Nix on macOS is as simple as: $ sudo nix-channel --update $ sudo nix-env -u $ sudo launchctl stop org.nixos.nix-daemon $ sudo launchctl start org.nixos.nix-daemon or $ sudo systemctl restart nix-daemon
2018-08-13 dirOf: allow use on non-absolute pathsLinus Heckemann1-1/+1
2018-05-30 Make <nix/fetchurl.nix> run in constant memoryEelco Dolstra1-0/+17
E.g. nix-build --store ~/my-nix/ -E 'import <nix/fetchurl.nix> { url = https://cache.nixos.org/nar/0nwi996rgq4b914qyx0mv2wq4k80hjac7xilikavagw7kxmn2iiv.nar.xz; sha256 = "0nwi996rgq4b914qyx0mv2wq4k80hjac7xilikavagw7kxmn2iiv"; }' now runs in 17 MiB (was 70 MiB), while nix-build --store ~/my-nix/ -E 'import <nix/fetchurl.nix> { url = https://cache.nixos.org/nar/0nwi996rgq4b914qyx0mv2wq4k80hjac7xilikavagw7kxmn2iiv.nar.xz; sha256 = "0d2fxljdih3nc5dqx41hjzic3141ajil94m8kdbpryq569dpsbvb"; unpack = true; }' runs in 17 MiB (was 346 MiB).
2018-05-30 Make LocalBinaryCacheStore::narFromPath() run in constant memoryEelco Dolstra1-1/+9
This reduces memory consumption of nix copy --from file://... --to ~/my-nix /nix/store/95cwv4q54dc6giaqv6q6p4r02ia2km35-blender-2.79 from 514 MiB to 18 MiB for an uncompressed binary cache, and from 192 MiB to 53 MiB for a bzipped binary cache. It may also be faster because fetching can happen concurrently with decompression/writing. Continuation of 48662d151bdf4a38670897beacea9d1bd750376a. Issue https://github.com/NixOS/nix/issues/1681.

2018-03-20 Hack to get SSH error messages from build-remoteEelco Dolstra1-3/+20
E.g. cannot build on 'ssh://mac1': cannot connect to 'mac1': bash: nix-store: command not found cannot build on 'ssh://mac2': cannot connect to 'mac2': Host key verification failed. cannot build on 'ssh://mac3': cannot connect to 'mac3': Received disconnect from 213... port 6001:2: Too many authentication failures Authentication failed.
2018-03-19 util: rename stdout/stdin members to avoid conflicts w/standard macroWill Dietz1-7/+7

2018-03-16 decompress(): Use a Source and SinkEelco Dolstra1-15/+60
This allows decompression to happen in O(1) memory.
2018-03-15 Filter ANSI colors when not writing to a terminalEelco Dolstra1-2/+2
Fixes https://github.com/NixOS/nixpkgs/issues/37114.

2018-02-26 nix run: Fix segfault on macOSEelco Dolstra1-0/+7
Note that clearenv() is not available on macOS. Fixes #1907.
2018-02-19 libutil: Fix infinite loop in filterANSIEscapes on '\r'Tuomas Tynkkynen1-1/+1
E.g. nix-instantiate --eval -E 'abort "\r"' hangs. Found by afl-fuzz.
2018-02-07 Improve filtering of ANSI escape sequences in build logsEelco Dolstra1-26/+41
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.
2018-01-16 Add pure evaluation modeEelco Dolstra1-0/+6
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.

2017-10-30 Fix (highly unlikely) race condition in readLinkTyson Whitehead1-12/+11
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).
