Motivation for this change

This adds macfsevents in order to fix #32087. This new package is required to fix pynotify on darwin.

Caveat

As of now this is still WIP, because during the checkPhase, I get a segmentation fault:

test_existing_directories_are_not_reported (tests.FileObservationTestCase) ... /nix/store/0igxxngigjgfkgg3cw547n92b8bpg6b1-stdenv-darwin/setup: line 1230: 45926 Segmentation fault: 11  /nix/store/4llw0i5jbb7p5n0r58w9z0azqgx5wk09-python-2.7.14/bin/python2.7 nix_run_setup test

Maybe someone could give me some pointers on how to proceed.
I guess this has something to do with the darwin headers on nixpkgs not actually matching the kernel version. (I'm on OS 10.11.6)

Things done
  • Tested using sandboxing (nix.useSandbox on NixOS, or option build-use-sandbox in nix.conf on non-NixOS)
  • Built on platform(s)
    • NixOS
    • macOS
    • other Linux distributions
  • Tested via one or more NixOS test(s) if existing and applicable for the change (look inside nixos/tests)
  • Tested compilation of all pkgs that depend on this change using nix-shell -p nox --run "nox-review wip"
  • Tested execution of all binary files (usually in ./result/bin/)
  • Fits CONTRIBUTING.md.

@LnL7 Do you have any tips on how to diagnose the segmentation fault for this darwin package?

Yes, python packages that depend on frameworks still suffer from #12346, #31865. Sadly interpreters need DYLD_FRAMEWORK_PATH as a workaround, both for tests like this case and in the final wrapper of the command that depends on it.

DYLD_FRAMEWORK_PATH=/System/Library/Frameworks

There's still the problem with the whole macOS frameworks don't work properly with python issue. I have no idea how to properly solve this except wrapping all downstream applications, which is somewhat ugly. I guess, I'm closing this for now.

makeWrapperArgs = [ "--set DYLD_FRAMEWORK_PATH /System/Library/Frameworks" ]

If this applies to all Darwin packages we may as well add it to the builder.
