I was able to turn this into a much smaller test case.
What is happening is that rebase works something like:
1. reset to "onto" commit
2. replay each commit between "upstream" and "branch"
but there is a bug in step 1 that is leaving the bogus
"public/dispatch.fcgi" file in the index and working tree. So step 2
correctly complains that the file is already there and uncommitted.
The bug in step 1 seems to be very hard to trigger, and requires that
the "branch" commit and the "onto" commit differ such that:
- there is a file on the branch that was a directory in "onto"
- there is a file on the branch that is new since "onto", and that
sorts lexically after the file mentioned above
So you can see that it is rare for it to come up. :)
I'm not sure of the correct fix for the bug, but I have posted a request
for help under the subject "bug in unpack_trees", so hopefully somebody
more wise than I will have something to say.
