[RFC,0/3] Parallel submodule status

Message

Atneya Nair March 5, 2024, 1:21 a.m. UTC

This set tries to speed up git status (and other commands which examine
the tree state) for repositories with many submodules.

Currently, submodules, unlike regular files, are examined serially
despite the expense of this operation. Fsmonitor also doesn't support
submodules, so there isn't a great alternative here.

Atneya Nair (3):
  Make read_gitfile and resolve_gitfile thread safe
  Make ce_compare_gitlink thread-safe
  Preload submodule state in refresh_index
