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
(cherry picked from commit c389a7fb617ed7bcd617efa68c6a48c00405310d)
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.

2017-11-20 Merge pull request #1645 from twhitehead/stat-raceEelco Dolstra1-12/+11
Fix (highly unlikely) race condition in readLink
2017-11-01 fetchMercurial: Don't fetch hashes we already haveEelco Dolstra1-15/+26
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).
2017-10-25 Pass lists/attrsets to bash as (associative) arraysEelco Dolstra1-0/+10
2017-09-08 ThreadPool: On exception, interrupt the other worker threadsEelco Dolstra1-1/+1
2017-08-29 readLink(): Handle symlinks in /procEelco Dolstra1-4/+5
Symlinks like /proc/self/exe report a stat() size of 0, so use a buffer of at least PATH_MAX instead.
2017-08-25 Handle SIGWINCHEelco Dolstra1-0/+28
2017-08-25 TypoEelco Dolstra1-1/+1
2017-08-18 Remove unused decodeOctalEscapedAndy Wingo1-15/+0
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".
2017-08-09 Use /proc/self/fd to efficiently close all FDs on LinuxEelco Dolstra1-2/+16
Issue #1506.

2017-07-11 replaceSymlink(): Handle the case where the temporary file already existsEelco Dolstra1-4/+13
Not really necessary anymore for #849, but still nice to have.

2017-04-25 nix repl: Use $XDG_DATA_HOME for the readline historyEelco Dolstra1-0/+12
2017-04-21 add helper function to set 'interruptThrown'David McFarland1-1/+6
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

2017-03-16 Remove "killing process <pid>" messagesEelco Dolstra1-3/+2
They convey no useful information.
2017-03-15 runProgram(): Distinguish between empty input and no inputEelco Dolstra1-10/+23
For example, if we call brotli with an empty input, it shouldn't read from the caller's stdin.
2017-03-15 Fix deadlock in runProgram() when input is larger than the pipe buffer sizeEelco Dolstra1-3/+9
2017-02-16 Support netrc in <nix/fetchurl.nix>Eelco Dolstra1-2/+2
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).
2017-02-08 Include config.h implicitly with '-include config.h' in CFLAGSTuomas Tynkkynen1-2/+0
Because config.h can #define things like _FILE_OFFSET_BITS=64 and not every compilation unit includes config.h, we currently compile half of Nix with _FILE_OFFSET_BITS=64 and other half with _FILE_OFFSET_BITS unset. This causes major havoc with the Settings class on e.g. 32-bit ARM, where different compilation units disagree with the struct layout. E.g.: diff --git a/src/libstore/globals.cc b/src/libstore/globals.cc @@ -166,6 +166,8 @@ void Settings::update() _get(useSubstitutes, "build-use-substitutes"); + fprintf(stderr, "at Settings::update(): &useSubstitutes = %p\n", &nix::settings.useSubstitutes); _get(buildUsersGroup, "build-users-group"); diff --git a/src/libstore/remote-store.cc b/src/libstore/remote-store.cc +++ b/src/libstore/remote-store.cc @@ -138,6 +138,8 @@ void RemoteStore::initConnection(Connection & conn) void RemoteStore::setOptions(Connection & conn) { + fprintf(stderr, "at RemoteStore::setOptions(): &useSubstitutes = %p\n", &nix::settings.useSubstitutes); conn.to << wopSetOptions Gave me: at Settings::update(): &useSubstitutes = 0xb6e5c5cb at RemoteStore::setOptions(): &useSubstitutes = 0xb6e5c5c7 That was not a fun one to debug!

2017-01-19 Kill builds when we get EOF on the log FDEelco Dolstra1-23/+10
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.
2017-01-17 Handle SIGINT etc. via a sigwait() signal handler threadEelco Dolstra1-4/+66
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.

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);
