2021-10-14add pos to EvalState::forceValueKevin Amado
- This way we improve error messages on infinite recursion - Demo: ```nix let x = builtins.fetchMercurial x; in x ``` - Before: ```bash $ nix-instantiate --show-trace --strict error: infinite recursion encountered ``` - After: ```bash nix-instantiate --show-trace --strict error: infinite recursion encountered at /data/github/kamadorueda/test/default.nix:2:7: 1| let 2| x = builtins.fetchMercurial x; | ^ 3| in ``` Mentions: #3505

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.

2021-10-11(partially) Revert "Don't copy in rethrow"regnat
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.

2021-10-07Allow builtins.{path,filterSource} on paths with a contextEelco Dolstra
We now build the context (so this has the side-effect of making builtins.{path,filterSource} work on derivations outputs, if IFD is enabled) and then check that the path has no references (which is what we really care about).

2021-10-06libexpr: remove matchAttrs boolean from ExprLambdaAndreas Rammhold
The boolean is only used to determine if the formals are set to a non-null pointer in all our cases. We can get rid of that allocation and instead just compare the pointer value with NULL. Saving up to sizeof(bool) + platform specific alignment per ExprLambda instace. Probably not a lot of memory but perhaps a few kilobyte with nixpkgs? This also gets rid of a potential issue with dereferencing formals based on the value of the boolean that didn't have to be aligned with the formals pointer but was in all our cases.

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.
