2017-02-07Merge branch 'nix-copy-closure-c++' of https://github.com/shlevy/nixEelco Dolstra
2017-02-07Add a LegacySSHStore that uses nix-store --serveEelco Dolstra
This is useful for nix-copy-closure.
2017-02-07copyStorePath(): Don't require signatures for "trusted" storesEelco Dolstra
For example, SSH stores could be trusted.
2017-02-07Provide default implementations for a couple of Store methodsEelco Dolstra
2017-02-07SSHStore: uri -> hostEelco Dolstra
2017-02-07CleanupEelco Dolstra
2017-02-02exportReferencesGraph: Only export in JSON format when in structured modeEelco Dolstra
This prevents breaking compatibility with builders that read "closure.*", since they would accidentally pick up the new JSON files.
2017-02-01Restore default signal handling in child processesEelco Dolstra
In particular, this fixes Ctrl-C in nix-shell sessions.
2017-01-27Periodically purge binary-cache.sqliteEelco Dolstra
2017-01-27Implement TTL for binary cache lookupsEelco Dolstra
2017-01-27Remove unused NARExistence tableEelco Dolstra
2017-01-26exportReferencesGraph: Export more complete info in JSON formatEelco Dolstra
This writes info about every path in the closure in the same format as ‘nix path-info --json’. Thus it also includes NAR hashes and sizes. Example: [ { "path": "/nix/store/10h6li26i7g6z3mdpvra09yyf10mmzdr-hello-2.10", "narHash": "sha256:0ckdc4z20kkmpqdilx0wl6cricxv90lh85xpv2qljppcmz6vzcxl", "narSize": 197648, "references": [ "/nix/store/10h6li26i7g6z3mdpvra09yyf10mmzdr-hello-2.10", "/nix/store/27binbdy296qvjycdgr1535v8872vz3z-glibc-2.24" ], "closureSize": 20939776 }, { "path": "/nix/store/27binbdy296qvjycdgr1535v8872vz3z-glibc-2.24", "narHash": "sha256:1nfn3m3p98y1c0kd0brp80dn9n5mycwgrk183j17rajya0h7gax3", "narSize": 20742128, "references": [ "/nix/store/27binbdy296qvjycdgr1535v8872vz3z-glibc-2.24" ], "closureSize": 20742128 } ] Fixes #1134.
2017-01-26Add support for passing structured data to buildersEelco Dolstra
Previously, all derivation attributes had to be coerced into strings so that they could be passed via the environment. This is lossy (e.g. lists get flattened, necessitating configureFlags vs. configureFlagsArray, of which the latter cannot be specified as an attribute), doesn't support attribute sets at all, and has size limitations (necessitating hacks like passAsFile). This patch adds a new mode for passing attributes to builders, namely encoded as a JSON file ".attrs.json" in the current directory of the builder. This mode is activated via the special attribute __structuredAttrs = true; (The idea is that one day we can set this in stdenv.mkDerivation.) For example, stdenv.mkDerivation { __structuredAttrs = true; name = "foo"; buildInputs = [ pkgs.hello pkgs.cowsay ]; doCheck = true; hardening.format = false; } results in a ".attrs.json" file containing (sans the indentation): { "buildInputs": [], "builder": "/nix/store/ygl61ycpr2vjqrx775l1r2mw1g2rb754-bash-4.3-p48/bin/bash", "configureFlags": [ "--with-foo", "--with-bar=1 2" ], "doCheck": true, "hardening": { "format": false }, "name": "foo", "nativeBuildInputs": [ "/nix/store/10h6li26i7g6z3mdpvra09yyf10mmzdr-hello-2.10", "/nix/store/4jnvjin0r6wp6cv1hdm5jbkx3vinlcvk-cowsay-3.03" ], "propagatedBuildInputs": [], "propagatedNativeBuildInputs": [], "stdenv": "/nix/store/f3hw3p8armnzy6xhd4h8s7anfjrs15n2-stdenv", "system": "x86_64-linux" } "passAsFile" is ignored in this mode because it's not needed - large strings are included directly in the JSON representation. It is up to the builder to do something with the JSON representation. For example, in bash-based builders, lists/attrsets of string values could be mapped to bash (associative) arrays.
2017-01-26Fix assertion failure when a path is lockedEelco Dolstra
Fixes: nix-store: src/libstore/build.cc:3649: void nix::Worker::run(const Goals&): Assertion `!awake.empty()' failed.
2017-01-26UserLock: Fix multi-threaded access to a global variableEelco Dolstra
2017-01-26openLockFile: Return an AutoCloseFDEelco Dolstra
2017-01-26UserLock: Make more RAII-ishEelco Dolstra
2017-01-26Moving more code out of DerivationGoal::startBuilder()Eelco Dolstra
2017-01-26On HTTP errors, also show the curl errorEelco Dolstra
This is a hopefully temporary measure to diagnose the intermittent "HTTP error 200" failures.
2017-01-26Move exportReferencesGraph into a separate methodEelco Dolstra
startBuilder() is getting rather obese.
2017-01-24Enable verbose curl outputEelco Dolstra
Closes #1182.
2017-01-20nix-copy-closure: Implement in C++.Shea Levy
Tests fail currently because the database is not given proper hashes in the VM
2017-01-19Merge pull request #981 from shlevy/build-remote-c++Eelco Dolstra
build-remote: Implement in C++
2017-01-19Kill builds when we get EOF on the log FDEelco Dolstra
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.
2017-01-19Use std::unique_ptr for HookInstanceEelco Dolstra
2017-01-17Handle SIGINT etc. via a sigwait() signal handler threadEelco Dolstra
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.
2017-01-16AutoCloseDir: Use std::unique_ptrEelco Dolstra
2017-01-16AutoDeleteArray -> std::unique_ptrEelco Dolstra
Also, switch to C++14 for std::make_unique.

Simplify remouting with MS_PRIVATE in sandbox build
2017-01-02Provide /var/run/nscd/socket in the sandboxEelco Dolstra
Otherwise sandbox builds can fail, e.g. $ NIX_REMOTE=local?root=/tmp/nix nix-build '<nixpkgs>' -A hello --option build-use-substitutes false ... downloading ‘http://ftpmirror.gnu.org/bash/bash-4.3-patches/bash43-047’... error: unable to download ‘http://ftpmirror.gnu.org/bash/bash-4.3-patches/bash43-047’: Couldn't resolve host name (6)

This is required now.

2016-12-19Revert "Merge branch 'seccomp' of https://github.com/aszlig/nix"Eelco Dolstra
This reverts commit 9f3f2e21edb17dbcd674539dff96efb6cceca10c, reversing changes made to 47f587700d646f5b03a42f2fa57c28875a31efbe.

2016-12-15Give root a valid home directoryEelco Dolstra
Some programs barf if the current user has a non-writable home directory, e.g. http://hydra.nixos.org/build/44818144.

2016-12-08Don't delete .check directories of running buildsEelco Dolstra
We need to keep them around for diffoscope.

2016-12-08S3BinaryCacheStore: Ensure it only builds on LinuxEelco Dolstra
2016-12-08Fix S3BinaryCacheStoreEelco Dolstra
It failed with AWS error uploading ‘6gaxphsyhg66mz0a00qghf9nqf7majs2.ls.xz’: Unable to parse ExceptionName: MissingContentLength Message: You must provide the Content-Length HTTP header. possibly because the istringstream_nocopy introduced in 0d2ebb4373e509521f27a6e8f16bfd39d05b2188 doesn't supply the seek method that the AWS library expects. So bring back the old version, but only for S3BinaryCacheStore.
2016-12-07Add a hook to run diffoscope when non-determinism is detectedEelco Dolstra
2016-12-07Keep track of the exact build start/stop timesEelco Dolstra
2016-12-07Bail out early when non-determinism is detectedEelco Dolstra
2016-12-07Add an option to make non-determinism non-fatalEelco Dolstra
That is, when build-repeat > 0, and the output of two rounds differ, then print a warning rather than fail the build. This is primarily to let Hydra check reproducibility of all packages.
