My repo has a change where a directory named Src was renamed to src.   
When I run "git filter-branch HEAD", my repo history is  rewritten so  
it appears that the Src directory was simply deleted.  I'm using case  
insensitive HFS+.
Fortunately, I can work around this by using -d to work off a case  
sensitive HFS+ volume - "git filter-branch -d /Volumes/CaseSensitive/ 
test HEAD" correctly changes nothing.

Anyone know why this happens?

Jon

That is no problem for git-filter-branch.

That is the problem.

Of course, we could work around that in git, but frankly, you will turn 
into problems once you have files whose names differ only in case.  And I 
am certain somebody will come soon and report this as a bug in git!

I vote for wont-fix (or more accurately "invalid") in git and 
please-fix-in-your-setup.

Ciao,

Would love to switch to case sensitive HFS+, but it causes a number of  
problems for OS X users - a number of 3rd party applications don't  
bother supporting case sensitive formatting (notably Adobe :/ ).


I appreciate that it's difficult and/or impossible to make certain  
operations work on case insensitive FS's, but it seems like git ought  
to at least complain noisily when it encounters such a situation...
