"Case folding" error trying to clone a mercurial repo

Question

I try to clone a local mercurial repository on windows.

I get this error:

   C:\temp\toolkit1.1>hg clone \src\toolkit
   destination directory: toolkit
   updating working directory
   abort: case-folding collision between sdk/Api.h and sdk/api.h

It looks like I changed capitalization of API.H at some point, but I don't know how to resolve this. Any tips?

I am using the version: 1.2.1

Answer 1

This is a problem that sometimes occurs when you work with a Mercurial repository on a case-insensitive file system (Windows). See the Fixing Case Collisions on the Mercurial wiki.

Probably the easiest is if you have access to a Unix computer check out the project there and remove the offending file, merging changes first (if any), then commit and push.

Answer 2

I fixed this by renaming the file in windows to Api.h.old. Committing that. Then renaming to Api.h with corrected capitalization. Commiting again.

Then clone worked.
