2016-02-24 Remove bad daemon connections from the poolEelco Dolstra4-14/+55
This is necessary for long-running processes like hydra-queue-runner: if a nix-daemon worker is killed, we need to stop reusing that connection.
2016-02-23 Pool<T>: Allow a maximum pool sizeEelco Dolstra4-33/+74
2016-02-23 RemoteStore: Make thread-safeEelco Dolstra4-235/+414
This allows a RemoteStore object to be used safely from multiple threads concurrently. It will make multiple daemon connections if necessary. Note: pool.hh and sync.hh have been copied from the Hydra source tree.
2016-02-23 Move ref<t> into a separate headerEelco Dolstra2-59/+69
2016-02-22 DohEelco Dolstra1-1/+1
2016-02-22 Make OpenSSL usage thread-safeEelco Dolstra3-4/+26
OpenSSL can randomly segfault unless we register a callback function to do locking. https://www.openssl.org/docs/manmaster/crypto/threads.html
2016-02-22 curl: Set CURLOPT_NOSIGNALEelco Dolstra1-0/+2
Otherwise using curl is not safe in multi-threaded applications because it installs a SIGALRM handler.
2016-02-19 JSONObject: Support floats and booleansEelco Dolstra1-1/+12
2016-02-17 Fix build without sodiumEelco Dolstra2-5/+11
http://hydra.nixos.org/build/32085949
2016-02-16 Add C++ functions for .narinfo processing / signingEelco Dolstra5-1/+297
This is currently only used by the Hydra queue runner rework, but like eff5021eaa6dc69f65ea1a8abe8f3ab11ef5eb0a it presumably will be useful for the C++ rewrite of nix-push and download-from-binary-cache. (@shlevy)
2016-02-16 Rename ValidPathInfo::hash -> narHash for consistencyEelco Dolstra7-31/+31
2016-02-15 Add xz compression functionEelco Dolstra2-0/+42
This is used by the Hydra queue runner, but since it may also be useful for the C++ rewrite of nix-push, I'm putting it here.
2016-02-15 decompressXZ: Ensure that lzma_end() is calledEelco Dolstra1-12/+21
Otherwise we might leak memory.
2016-02-15 Expose the export magic value and move LocalStore::queryReferences to StoreEelco Dolstra4-22/+19
2016-02-15 Fix broken number parsing in fromJSONEelco Dolstra1-4/+3
The call to tmp_number.append had its arguments mixed up. Also, JSON does not allow a trailing "," after array/object members.
2016-02-15 Add function to extract hash part of a store pathEelco Dolstra3-2/+15
2016-02-12 Merge pull request #762 from ctheune/ctheune-floatsEelco Dolstra16-23/+185
Implement floats
2016-02-11 Move addPermRoot into StoreEelco Dolstra5-16/+15
2016-02-11 ref<T>: Add cast operatorEelco Dolstra2-15/+8
2016-02-04 More of the sameEelco Dolstra5-13/+13
2016-02-04 StoreAPI -> StoreEelco Dolstra23-48/+48
Calling a class an API is a bit redundant...
2016-02-04 Eliminate the "store" global variableEelco Dolstra35-414/+480
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.)
2016-01-31 Add build mode to compute fixed-output derivation hashesEelco Dolstra3-7/+34
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 Dolstra1-7/+38
Similar to 00903fa79961d7eb0fadeb9ed2d7cda7821dc293. Regardless of -K, we now also print which output differs.
2016-01-12 Canonicalize gids to 0Eelco Dolstra1-2/+2
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 Dolstra1-2/+12
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 Dolstra1-1/+1
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 Dolstra1-1/+1
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.
2016-01-07 Fix "Bad address" executing build hookEelco Dolstra1-5/+9
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...

2016-01-06 Fix --repair failure on multiple-output derivationsEelco Dolstra1-1/+3
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
2016-01-06 @eelco's feedback: downgrade to regular float for size, remove unused function.Christian Theune2-24/+1
2016-01-05 Better error messageFabian Schmitthenner1-1/+1
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.
2016-01-05 Fix compilationEelco Dolstra1-1/+7
2016-01-05 Use __toString when coercing sets to strings.Shea Levy2-2/+10
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.
