2016-09-12 Fix build on GCC 4.9Eelco Dolstra1-11/+8
GCC 4.9 doesn't like reassigning a std::stringstream. http://hydra.nixos.org/build/40371644
2016-09-12 Write "T x" instead of "auto x = T"Eelco Dolstra1-35/+32
That's just silly. Hopefully this also fixes the Debian build failure: http://hydra.nixos.org/build/40371644
2016-09-08 Don't run builds as root in the user namespaceEelco Dolstra1-16/+31
This largely reverts c68e5913c71badc89ff346d1c6948517ba720c93. Running builds as root breaks "cp -p", since when running as root, "cp -p" assumes that it can succesfully chown() files. But that's not actually the case since the user namespace doesn't provide a complete uid mapping. So it barfs with a fatal error message ("cp: failed to preserve ownership for 'foo': Invalid argument").

2016-09-08 Fix assertion failure after early build setup failureEelco Dolstra1-1/+1
2016-09-08 Fix early removal of rc-file for nix-shellShea Levy1-2/+0
BASH_ENV causes all non-interactive shells called via eg. /etc/bashrc to remove the rc-file before the main shell gets to run it. Completion scripts will often do this. Fixes #976. Adapted from and fixes #1034.

2016-08-30 Increase the sleep time between download retriesEelco Dolstra3-2/+4
2016-08-30 Fix --fallbackEelco Dolstra1-7/+10
This fixes an assertion failure in "assert(goal);" in Worker::waitForInput() after a substitution goal is cancelled by the termination of another goal. The problem was the line //worker.childTerminated(shared_from_this()); // FIXME in the SubstitutionGoal destructor. This was disabled because shared_from_this() obviously doesn't work from a destructor. So we now use a real pointer for object identity.

2016-08-29 forceBool(): Show position infoEelco Dolstra4-13/+14
2016-08-29 Add builtin function "partition"Eelco Dolstra5-10/+48
The implementation of "partition" in Nixpkgs is O(n^2) (because of the use of ++), and for some reason was causing stack overflows in multi-threaded evaluation (not sure why). This reduces "nix-env -qa --drv-path" runtime by 0.197s and memory usage by 298 MiB (in non-Boehm mode).
2016-08-29 nix path-info: Add --json flagEelco Dolstra7-129/+472
Also, factor out JSON generation from value-to-json.{cc,hh}, and support producing indented JSON.
2016-08-29 callFunction: Copy functors to the heapShea Levy1-4/+11
Normally it's impossible to take a reference to the function passed to callFunction, so some callers (e.g. ExprApp::eval) allocate that value on the stack. For functors, a reference to the functor itself may be kept, so we need to have it on the heap. Fixes #1045
2016-08-24 Fix queryPathFromHashPart()Eelco Dolstra1-1/+1
The inner lambda was returning a SQLite-internal char * rather than a std::string, leading to Hydra errors liks Caught exception in Hydra::Controller::Root->narinfo "path ‘ø˜£â€™ is not in the Nix store at /nix/store/6mvvyb8fgwj23miyal5mdr8ik4ixk15w-hydra-0.1.1234.abcdef/libexec/hydra/lib/Hydra/Controller/Root.pm line 352."
2016-08-23 nix build: Use Nix search pathEelco Dolstra5-13/+57
That is, unless --file is specified, the Nix search path is synthesized into an attribute set. Thus you can say $ nix build nixpkgs.hello assuming $NIX_PATH contains an entry of the form "nixpkgs=...". This is more verbose than $ nix build hello but is less ambiguous.

2016-08-17 Add a mechanism for derivation attributes to reference the derivation's outputsEelco Dolstra4-14/+38
For example, you can now say: configureFlags = "--prefix=${placeholder "out"} --includedir=${placeholder "dev"}"; The strings returned by the ‘placeholder’ builtin are replaced at build time by the actual store paths corresponding to the specified outputs. Previously, you had to work around the inability to self-reference by doing stuff like: preConfigure = '' configureFlags+=" --prefix $out --includedir=$dev" ''; or rely on ad-hoc variable interpolation semantics in Autoconf or Make (e.g. --prefix=\$(out)), which doesn't always work.

This makes us more robust against 500 errors from CloudFront or S3 (assuming the 500 error isn't cached by CloudFront...).

This makes it easier to create a diverted store, i.e. NIX_REMOTE="local?root=/tmp/root" instead of NIX_REMOTE="local?real=/tmp/root/nix/store&state=/tmp/root/nix/var/nix" NIX_LOG_DIR=/tmp/root/nix/var/log
