2021-10-26parseExperimentalFeature(): Initialize atomicallyEelco Dolstra
2021-10-26Make experimental-features a proper typeregnat
Rather than having them plain strings scattered through the whole codebase, create an enum containing all the known experimental features. This means that - Nix can now `warn` when an unkwown experimental feature is passed (making it much nicer to spot typos and spot deprecated features) - It’s now easy to remove a feature altogether (once the feature isn’t experimental anymore or is dropped) by just removing the field for the enum and letting the compiler point us to all the now invalid usages of it.

2021-10-06Don't reset the logger in a vforkEelco Dolstra
9c766a40cbbd3a350a9582d0fd8201e3361a63b2 broke logging from the daemon, because commonChildInit is called when starting the build hook in a vfork, so it ends up resetting the parent's logger. So don't vfork. It might be best to get rid of vfork altogether, but that may cause problems, e.g. when we call an external program like git from the evaluator.

With -vvvv, the ProgressBar was polluting the stderr of the child, messing up its \2 message to the parent.

2021-07-30libutil: initialize the base64 decode array only onceAndreas Rammhold
Previously, despite having a boolean that tracked initialization, the decode characters have been "calculated" every single time a base64 string was being decoded. With this change we only initialize the decode array once in a thread-safe manner.

Fill `NIX_CONFIG` with the value of the current Nix configuration before calling the post-build-hook. That way the whole configuration (including the possible `experimental-features`, a possibly `--store` option or whatever) will be made available to the hook

2021-05-26Recursively substitute the realisationsregnat
Make sure that whenever we substitute a realisation, we also substitute its entire closure
2021-05-19Extract a generic `computeClosure` functionregnat
Move the `closure` logic of `computeFSClosure` to its own (templated) function. This doesn’t bring much by itself (except for the ability to properly test the “closure” functionality independently from the rest), but it allows reusing it (in particular for the realisations which will require a very similar closure computation)
2021-05-18Fix extra slash in canonPath outputMatthew Bauer
When you have a symlink like: /tmp -> ./private/tmp you need to resolve ./private/tmp relative to /tmp’s dir: ‘/’. Unlike any other path output by dirOf, / ends with a slash. We don’t want trailing slashes here since we will append another slash in the next comoponent, so clear s like we would if it was a symlink to an absoute path. This should fix at least part of the issue in https://github.com/NixOS/nix/issues/4822, will need confirmation that it actually fixes the problem to close though. Introduced in f3f228700a52857fe6e8632df4e935551ea219ff.
2021-04-22Remove makeDecompressionSource()Eelco Dolstra
This function doesn't support all compression methods (i.e. 'none' and 'br') so it shouldn't be exposed. Also restore the original decompress() as a wrapper around makeDecompressionSink().
2021-04-22libutil: allow decompression with none/empty methodLuke Granger-Brown
The S3 store relies on the ability to be able to decompress things with an empty method, because it just passes the value of the Content-Encoding directly to decompress. If the file is not compressed, then this will cause the compression routine to get confused. This caused NixOS/nixpkgs#120120.
