Implement floats

2016-02-04More of the sameEelco Dolstra
2016-02-04StoreAPI -> StoreEelco Dolstra
Calling a class an API is a bit redundant...
2016-02-04Eliminate the "store" global variableEelco Dolstra
Also, move a few free-standing functions into StoreAPI and Derivation. Also, introduce a non-nullable smart pointer, ref<T>, which is just a wrapper around std::shared_ptr ensuring that the pointer is never null. (For reference-counted values, this is better than passing a "T&", because the latter doesn't maintain the refcount. Usually, the caller will have a shared_ptr keeping the value alive, but that's not always the case, e.g., when passing a reference to a std::thread via std::bind.)
2016-01-31Add build mode to compute fixed-output derivation hashesEelco Dolstra
For example, $ nix-build --hash -A nix-repl.src will build the fixed-output derivation nix-repl.src (a fetchFromGitHub call), but instead of *verifying* the hash given in the Nix expression, it prints out the resulting hash, and then moves the result to its content-addressed location in the Nix store. E.g build produced path ‘/nix/store/504a4k6zi69dq0yjc0bm12pa65bccxam-nix-repl-8a2f5f0607540ffe56b56d52db544373e1efb980-src’ with sha256 hash ‘0cjablz01i0g9smnavhf86imwx1f9mnh5flax75i615ml71gsr88’ The goal of this is to make all nix-prefetch-* scripts unnecessary: we can just let Nix run the real thing (i.e., the corresponding fetch* derivation). Another example: $ nix-build --hash -E 'with import <nixpkgs> {}; fetchgit { url = "https://github.com/NixOS/nix.git"; sha256 = "ffffffffffffffffffffffffffffffffffffffffffffffffffff"; }' ... git revision is 9e7c1a4bbdbe6129dd9dc385776612c307d3d1bb ... build produced path ‘/nix/store/gmsnh9i7x4mb7pyd2ns7n3c9l90jfsi1-nix’ with sha256 hash ‘1188xb621diw89n25rifqg9lxnzpz7nj5bfh4i1y3dnis0dmc0zp’ (Having to specify a fake sha256 hash is a bit annoying...)

2016-01-12--option build-repeat: Keep the differing output if -K is givenEelco Dolstra
Similar to 00903fa79961d7eb0fadeb9ed2d7cda7821dc293. Regardless of -K, we now also print which output differs.
2016-01-12Canonicalize gids to 0Eelco Dolstra
Previously files in the Nix store were owned by root or by nixbld, depending on whether they were created by a substituter or by a builder. This doesn't matter much, but causes spurious diffoscope differences. So use root everywhere.
2016-01-12--check: Keep the differing output if -K is givenEelco Dolstra
This makes it easier to investigate the non-determinism, e.g. $ nix-build pkgs/stdenv/linux -A stage1.pkgs.zlib --check -K error: derivation ‘/nix/store/l54i8wlw22656i4pk05c52ngv9rpl39q-zlib-1.2.8.drv’ may not be deterministic: output ‘/nix/store/11a27shh6n2ivi4a7s964i65ql80cf27-zlib-1.2.8’ differs from ‘/nix/store/11a27shh6n2ivi4a7s964i65ql80cf27-zlib-1.2.8-check’ $ diffoscope /nix/store/11a27shh6n2ivi4a7s964i65ql80cf27-zlib-1.2.8 /nix/store/11a27shh6n2ivi4a7s964i65ql80cf27-zlib-1.2.8-check ... ├── lib/libz.a │ ├── metadata │ │ @@ -1,15 +1,15 @@ │ │ -rw-r--r-- 30001/30000 3096 Jan 12 15:20 2016 adler32.o ... │ │ +rw-r--r-- 30001/30000 3096 Jan 12 15:28 2016 adler32.o ...
2016-01-12--check: Fix "failed to produce output path"Eelco Dolstra
This occured when sandbox building is disabled, at least one output exists, and at least one other output does not.
2016-01-12--check: Fix assertion failure when some outputs are missingEelco Dolstra
E.g. $ nix-build pkgs/stdenv/linux/ -A stage1.pkgs.perl --check nix-store: src/libstore/build.cc:1323: void nix::DerivationGoal::tryToBuild(): Assertion `buildMode != bmCheck || validPaths.size() == drv->outputs.size()' failed. when perl.out exists but perl.man doesn't. The fix is to only check the outputs that exist. Note that "nix-build -A stage1.pkgs.all --check" will still give a (proper) error in this case.
2016-01-07Fix "Bad address" executing build hookEelco Dolstra
This was observed in the deb_debian7x86_64 build: http://hydra.nixos.org/build/29973215 Calling c_str() on a temporary should be fine because the temporary shouldn't be destroyed until after the execl() call, but who knows...

2016-01-06Fix --repair failure on multiple-output derivationsEelco Dolstra
If repair found a corrupted/missing path that depended on a multiple-output derivation, and some of the outputs of the latter were not present, it failed with a message like error: path ‘/nix/store/cnfn9d5fjys1y93cz9shld2xwaibd7nn-bash-4.3-p42-doc’ is not valid

2016-01-05Better error messageFabian Schmitthenner
Also show types when nix cannot compare values of different types. This is also more consistent since types are already shown when comparing values of the same not comparable type.

2016-01-05Use __toString when coercing sets to strings.Shea Levy
For example, "${{ foo = "bar"; __toString = x: x.foo; }}" evaluates to "bar". With this, we can delay calling functions like mkDerivation, buildPythonPackage, etc. until we actually need a derivation, enabling overrides and other modifications to happen by simple attribute set update.

2016-01-04Don't allow sandbox profile except in relaxed modeEelco Dolstra
This makes Darwin consistent with Linux: Nix expressions can't break out of the sandbox unless relaxed sandbox mode is enabled. For the normal sandbox mode this will require fixing #759 however.
2016-01-04~PathLocks(): Handle exceptionsEelco Dolstra
Otherwise, since the call to write a "d" character to the lock file can fail with ENOSPC, we can get an unhandled exception resulting in a call to terminate().
2015-12-29Fix regression in passAsFileEelco Dolstra
Caused by 8063fc497ab78fa72962b93874fe25dcca2b55ed. If tmpDir != tmpDirInSandbox (typically when there are multiple concurrent builds with the same name), the *Path attribute would not point to an existing file. This caused Nixpkgs' writeTextFile to write an empty file. In particular this showed up as hanging VM builds (because it would run an empty run-nixos-vm script and then wait for it to finish booting).
2015-12-22Handle /tmp being a symlinkEelco Dolstra
Hopefully fixes Darwin sandbox regression introduced in 8063fc497ab78fa72962b93874fe25dcca2b55ed.

2015-12-17showId: Handle empty attribute namesEelco Dolstra
We should probably disallow these, but until then, we shouldn't barf with an assertion failure. Fixes #738.
