Please describe the problem.
The git annex assistant committer stops working and crashes under certain circumstances when dealing with small files.
This seems to occur when a small file is in the committer queue but is deleted before the queue is flushed.
What steps will reproduce the problem?
Set the annex.largefiles option to exclude certain files from the annex: git config annex.largefiles 'exclude=*.txt'.
Create and immediately delete some file that is excluded from the annex:
touch somefile.txt && rm somefile.txt
This will cause a "user error" to occur every time the committer thread tries to do a commit, essentially causing it to stop working.
In addition, if no file activity occurs for 5 minutes, creating another file will cause the committer to crash:
sleep 310
touch someotherfile.txt
What version of git-annex are you using? On what operating system?
Operating system: Arch Linux x86_64
git-annex version: 10.20230329
