Hello,
I noticed that check for filename collision on case insensitive
systems happen only upon clone:
https://github.com/git/git/blob/c522f061d551c9bb8684a7c3859b2ece4499b56b/entry.c#L499
and
https://github.com/git/git/blob/c522f061d551c9bb8684a7c3859b2ece4499b56b/unpack-trees.c#L445
What if collision exists on some commit that is checked out only after clone?
Is this behavior intentional (eg. for performance reasons)? If its a
bug, can I volunteer to solve it?
Best regards
Paweł

The OS will overwrite e.g. the content of "FILE.TXT" with "file.txt" if
both exist in the repo.
(Or the other way around)
As a result, "FILE.TXT" would have the contents of "file.txt" which is
typically different, and Git will report "FILE.TXT" as "modified".

That depends on the definition of "performance".
The Git-developpers have not yet implemented a better solution,
since most of them do such things in their spare time.
As a consequence, we haven't been able to measure the performance
on a computer running Git.
>If its a bug, can I volunteer to solve it?
I would call it a feature, worth to be implemented.
And of course, you are wellcome to solve it.
I (and probably many others) are happy to help with code-reviews
and other tips, hints, suggestions.
