Why does TortoiseHg randomly capitalize my file name on commit?

Question

The file is not capitalized in the directory. There is nothing that would indicate that the file is different from any other file. Yet, on commit, the file name is capitalized including the type "CS". What's up with that?

Answer 1

It's not just filenames. It can also happen to any segment of the file's path.

This was a recent bug in Mercurial itself on Windows (discussion). It seems to be resolved in Mercurial 2.1, which will be included with TortoiseHg 2.3. There is a release candidate available, TortoiseHg 2.3-rc, and the final release should be out in less than a week.
