Hello,

I’m not quite sure if this is to be considered a Windows specific bug. I’m
using Git-1.7.10-preview20120409 on Windows, but the problem exists in
previous versions.

When fast-exporting | fast-importing on Windows a repository with case only
renames, the resulting repository isn’t a copy of the initial repository.
This is because Windows repositories are created with core.ignorecase = true
by default.

The included script shows the problem: it creates a repository with
SomeFile.txt renamed to SOMEFILE.txt, then fast-export it and fast-import it
in two different repositories, with core.ignorecase=false and
core.ignorecase=true. The sha-1 of the second commit in the repository with
core.ignorecase=true is different from the initial repository because the
rename is ignored.
The situation is worse without rename detection on fast-export : the rename
becomes a delete.

I think the configuration variable core.ignorecase should be ignored by
fast-import, and case always taken into account in that case.

Kind regards,
