libexpr: Recognize newline in more places in lexer
2018-03-14 Use boost::format from the boost packageEelco Dolstra1-2/+2
Note that this only requires headers from boost so it doesn't add a runtime dependency. Also, use Nixpkgs 18.03.

2018-03-02 libexpr: Recognize newline in more places in lexerTuomas Tynkkynen4-0/+6
Flex's regexes have an annoying feature: the dot matches everything except a newline. This causes problems for expressions like: "${0}\ " where the backslash-newline combination matches this rule instead of the intended one mentioned in the comment: <STRING>\$|\\|\$\\ { /* This can only occur when we reach EOF, otherwise the above (...|\$[^\{\"\\]|\\.|\$\\.)+ would have triggered. This is technically invalid, but we leave the problem to the parser who fails with exact location. */ return STR; } However, the parser actually accepts the resulting token sequence ('"' DOLLAR_CURLY 0 '}' STR '"'), which is a problem because the lexer rule didn't assign anything to yylval. Ultimately this leads to a crash when dereferencing a NULL pointer in ExprConcatStrings::bindVars(). The fix does change the syntax of the language in some corner cases but I think it's only turning previously invalid (or crashing) syntax to valid syntax. E.g. "a\ b" and ''a''\ b'' were previously syntax errors but now both result in "a\nb". Found by afl-fuzz.

2018-02-26 libexpr: Fix prim_replaceStrings() to work on an empty source stringTuomas Tynkkynen2-1/+4
Otherwise, running e.g. nix-instantiate --eval -E --strict 'builtins.replaceStrings [""] ["X"] "abc"' would just hang in an infinite loop. Found by afl-fuzz. First attempt of this was reverted in e2d71bd1862cdda because it caused another infinite loop, which is fixed now and a test added.

This reverts commit 4ea9707591beceacf9988b3c185faf50da238403. It causes an infinite loop in Nixpkgs evaluation, e.g. "nix-instantiate -A hello" hung. PR #1886.

2018-02-13 Fix #1762Linus Heckemann2-0/+11
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.

2018-02-07 Improve filtering of ANSI escape sequences in build logsEelco Dolstra1-1/+1
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.
2018-02-07 Merge pull request #1816 from shlevy/add-pathEelco Dolstra3-0/+9
Add path primop.
2018-02-06 Add path primop.Shea Levy3-0/+9
builtins.path allows specifying the name of a path (which makes paths with store-illegal names now addable), allows adding paths with flat instead of recursive hashes, allows specifying a filter (so is a generalization of filterSource), and allows specifying an expected hash (enabling safe path adding in pure mode).
2018-02-06 realiseContext(): Add derivation outputs to the allowed pathsEelco Dolstra1-0/+2
This makes import-from-derivation work in restricted mode again.
2018-02-05 Fix evaluationEelco Dolstra1-1/+1
2018-02-03 Remove nix-build --hashEelco Dolstra1-3/+10
Instead, if a fixed-output derivation produces has an incorrect output hash, we now unconditionally move the outputs to the path corresponding with the actual hash and register it as valid. Thus, after correcting the hash in the Nix expression (e.g. in a fetchurl call), the fixed-output derivation doesn't have to be built again. It would still be good to have a command for reporting the actual hash of a fixed-output derivation (instead of throwing an error), but "nix-build --hash" didn't do that.

2018-01-16 Add pure evaluation modeEelco Dolstra7-2/+47
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.

2017-12-30 use libbrotli directly when availableWill Dietz3-1/+31
* 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)
