rust: fix possible out-of-bounds read through index_get_parents()...
rust: fix possible out-of-bounds read through index_get_parents() index_get_parents() is an internal function, which doesn't check if the specified rev is valid. If rustlazyancestors() were instantiated with an invalid stoprev, it would access to invalid memory region. This is NOT a security fix as there's no Python code triggering the bug, but included in this series to not give a notion about the memory issue fixed by the previous patch.

Integration with the share extension needs improvement. Right now we've seen some odd bugs.

Address commentary in manifest.excludedmanifestrevlog.add - specifically we should improve the collaboration with core so that add() never gets called on an excluded directory and we can improve the stand-in to raise a ProgrammingError.

Reason more completely about rename-filtering logic in narrowfilelog. There could be some surprises lurking there.

Formally document the narrowspec format. For bonus points, unify with the server-specified narrowspec format.

narrowrepo.setnarrowpats() or narrowspec.save() need to make sure they're holding the wlock.

The follinwg places do an unrestricted dirstate walk (including files outside the narrowspec). Some of them should perhaps not do that.

  • debugfileset
  • perfwalk
  • sparse (but restricted to sparse config)
  • largefiles
