Mercurial ignores a file rename (changing case)

Question

I'm working with a project I inherited from a Windows guy. It's under Hg version control. It got some inconsistent filename convention which I'm trying to fix so I renamed a file named jquery.fullpage.js to jquery.fullPage.js (just uppercased "P") to adhere to the original author of that jQuery library.

However, Hg doesn't detect the lowercase-uppercase change as a rename or even as deleted/created file. As a result, I can't commit that change and push it live. It works locally but on the remote staging server where I pushed, it gives 404 errors. Apparently, the files on the remote weren't renamed to the uppercase P.

I know I can fix this by deleting the file, commit, restore the file and rename, commit again but that seems to be a crude way of fixing it.

How do I fix this?

Answer 1

This is a case folding problem. Try to rename the file through Mercurial: hg rename jquery.fullpage.js jquery.fullPage.js.

Answer 2

If you're renaming a file you are good to go with hg rename as already said.

However (at least on Windows), if you're renaming a folder then you can't rename it directly. The common workaround is to use an intermediate:

hg rename Foo tmp
hg rename tmp foo

Another workaround is using intermediate delete. But this is discouraged because you would lose the file history.
