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.

Currently machine specification (`/etc/nix/machine`) parser fails with a vague exception if the file had incorrect format. This commit adds verbose exceptions and unit-tests for the parser.

2021-10-14pathInfoCache: Use the entire base name as the cache keyEelco Dolstra
This fixes a bug in the garbage collector where if a path /nix/store/abcd-foo is valid, but we do a isValidPath("/nix/store/abcd-foo.lock") first, then a negative entry for /nix/store/abcd is added to pathInfoCache, so /nix/store/abcd-foo is subsequently considered invalid and deleted.

2021-10-13Fix GC when there are cycles in the referrers graphEelco Dolstra
(where "referrers" includes the reverse of derivation outputs and derivers). Now we do a full traversal to look if we can reach any root. If not, all paths reached can be deleted.

2021-10-13Non-blocking garbage collectorEelco Dolstra
The garbage collector no longer blocks other processes from adding/building store paths or adding GC roots. To prevent the collector from deleting store paths just added by another process, processes need to connect to the garbage collector via a Unix domain socket to register new temporary roots.

This reverts some parts of commit 8430a8f0866e4463a891ccce62779ea9ac0f3b38 which was trying to rethrow some exceptions while we weren’t in the context of a `catch` block, causing some weird “terminate called without an active exception” errors. Fix #5368

2021-10-07nix repl: properly deal with interruptionsMaximilian Bosch
When I stop a download with Ctrl-C in a `nix repl` of a flake, the REPL refuses to do any other downloads: nix-repl> builtins.getFlake "nix-serve" [0.0 MiB DL] downloading 'https://api.github.com/repos/edolstra/nix-serve/tarball/e9828a9e01a14297d15ca41 error: download of 'https://api.github.com/repos/edolstra/nix-serve/tarball/e9828a9e01a14297d15ca416e5a9415d4972b0f0' was interrupted [0.0 MiB DL] nix-repl> builtins.getFlake "nix-serve" error: interrupted by the user [0.0 MiB DL] To fix this issue, two changes were necessary: * Reset the global `_isInterrupted` variable: only because a single operation was aborted, it should still be possible to continue the session. * Recreate a `fileTransfer`-instance if the current one was shut down by an abort.

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.

to debug Before the changes when building the whole system with `contentAddressedByDefault = true;` we get many noninformative messages: $ nix build -f nixos system --keep-going ... warning: rewriting hashes in '/nix/store/...-clang-11.1.0.drv.chroot/nix/store/...-11.1.0'; cross fingers warning: rewriting hashes in '/nix/store/...-clang-11.1.0.drv.chroot/nix/store/...-11.1.0-dev'; cross fingers warning: rewriting hashes in '/nix/store/...-clang-11.1.0.drv.chroot/nix/store/...-11.1.0-python'; cross fingers error: 2 dependencies of derivation '/nix/store/...-hub-2.14.2.drv' failed to build warning: rewriting hashes in '/nix/store/...-subversion-1.14.1.drv.chroot/nix/store/...-subversion-1.14.1-dev'; cross fingers warning: rewriting hashes in '/nix/store/...-subversion-1.14.1.drv.chroot/nix/store/...-subversion-1.14.1-man'; cross fingers ...

2021-09-30`std::visit` by referenceJohn Ericson
I had started the trend of doing `std::visit` by value (because a type error once mislead me into thinking that was the only form that existed). While the optomizer in principle should be able to deal with extra coppying or extra indirection once the lambdas inlined, sticking with by reference is the conventional default. I hope this might even improve performance.

build: also throw hash-mismatch errors if `buildMode == bmCheck`
2021-09-27build: also throw hash-mismatch errors if `buildMode == bmCheck`Maximilian Bosch
This actually bit me quite recently in `nixpkgs` because I assumed that `nix-build --check` would also error out if hashes don't match anymore[1] and so I wrongly assumed that I couldn't reproduce the mismatch error. The fix is rather simple, during the output registration a so-called `delayedException` is instantiated e.g. if a FOD hash-mismatch occurs. However, in case of `nix-build --check` (or `--rebuild` in case of `nix build`), the code-path where this exception is thrown will never be reached. By adding that check to the if-clause that causes an early exit in case of `bmCheck`, the issue is gone. Also added a (previously failing) test-case to demonstrate the problem. [1] https://github.com/NixOS/nixpkgs/pull/139238, the underlying issue was that `nix-prefetch-git` returns different hashes than `fetchgit` because the latter one fetches submodules by default.

2021-09-23Shut down write side before draining the read sideEelco Dolstra
This is important if the remote side *does* execute nix-store/nix-daemon successfully, but stdout is polluted (e.g. because the remote user's bashrc script prints something to stdout). In that case we have to shutdown the write side to force the remote nix process to exit.
