Launches git cat-file processes which never die #1208
Description
I'm using this package to clone many repos. It's part of a utility which clones all repos under a GitLab group.
While running it I noticed over 6k git processes (and growing). See output below.
They're all git cat-file some with --batch-check and some with --batch.
Doing a search of this repo for batch_check I found these lines:
cmd = self._get_persistent_cmd("cat_file_header", "cat_file", batch_check=True)
# and ...
cmd = self._get_persistent_cmd("cat_file_all", "cat_file", batch=True)I guess emphasis on persistent right?
Are these processes meant to never die? What purpose do they serve?
Gather, count, and look at the procs
