Hi,
I discovered this while rebasing a branch after having converted files
to use LF line endings. I got around the problem by using
--ignore-whitespace but the error still seems strange to me so I'm
reporting it.
The following script is equivalent: it creates a repo with a CRLF file,
creates a "feature" branch, converts the file and then tries to rebase
the feature branch with git rebase -X ignore-whitespace-at-eol:
git init
echo "That's some catch, that Catch-1984" >file.txt
unix2dos file.txt
git add file.txt
git commit -m 'Initial commit'
git checkout -b feature
ex -sc 's/1984/22/|x' file.txt
git commit -m "Fix literary confusion" file.txt
git checkout master
echo '* text=auto' > .gitattributes
dos2unix file.txt
git add .
git commit -m 'CRLF to LF'
git checkout feature
gti config merge.renormalize true
git rebase -X ignore-space-at-eol master
While rebasing the following error appears:
error: addinfo_cache failed for path 'file.txt'
It comes from the git-merge-recursive invocation git-rebase performs[1]
and is printed because make_cache_entry() fails[2]. I also get this
error when using the other 'ignore-*' strategy options, as well as
'theirs'.
At this point file.txt still has its CRLF terminator, but simply:
git add file.txt
git rebase --continue
has the desired effect (as it did in my real life situation). I've
tested this on Git 2.2.0, 2.1.3 and 1.9.0.
I don't know whether this is actually related to git-rebase. It's a way
to reproduce it if nothing else. I haven't tried any experiments with
git-merge-recursive directly, I get the impression I'm not supposed to
since it doesn't have a manpage ;) Interestingly, removing the creation
of .gitattributes makes the problem go away.
Additionally, git-merge-recursive exits with status 0. This confuses
git-rebase which will continue and then complain about the state of the
index. (Interestingly, at this point my prompt thingy complains that
.git/rebase-merge/done isn't there).
Regards,
Øsse
