I'm experiencing an annoying issue which leaves the repository in a
weird, broken state. I am attempting a rather vanilla rebase, rebasing
the commits from a feature branch on top of the newest commits on
master.
So, I run a typical series of commands:
1. git checkout feature-branch
2. git rebase master (conflicts ensue)
3. git mergetool
The conflicts are expected, but when using mergetool to resolve them,
I encounter many "no such file or directory" errors.
mv: cannot stat
‘app/components/mediaManager/kbImageEditor.directive.coffee’: No such
file or directory
cp: cannot stat
‘./app/components/mediaManager/kbImageEditor.directive_BACKUP_13615.coffee’:
No such file or directory
mv: cannot move ‘.merge_file_ogGjXX’ to
‘./app/components/mediaManager/kbImageEditor.directive_BASE_13615.coffee’:
No such file or directory
/usr/lib/git-core/git-mergetool: 229: /usr/lib/git-core/git-mergetool:
cannot create ./app/components/mediaManager/kbImageEditor.directive_LOCAL_13615.coffee:
Directory nonexistent
/usr/lib/git-core/git-mergetool: 229: /usr/lib/git-core/git-mergetool:
cannot create ./app/components/mediaManager/kbImageEditor.directive_REMOTE_13615.coffee:
Directory nonexistent
This leaves weird dangling files like '.merge_file_ogGjXX' in the
repo, and I assume I should not proceed with the merge since it
couldn't even create the files to compare.
Is this a known issue? Is there any workaround? Is it safe to proceed
with the merge?
Thanks,
Joe Einertson

Can you tell us a little more about what's in the branch being
rebased? Is it perhaps a public project that you can share so
that we can reproduce the issue?
Here are a few more questions that can help narrow down the
issue:
* What Git vesion are you using?
* What mergetool are you using?
- See the output "git config merge.tool"
* What platform are you on? Are you on Windows?
* Does the conflicting commit contain renames?
I'm trying to figure out whether we are missing a `mkdir -p`
somewhere, and whether we hadn't run into this in the past
because the merge needs to involve renames.

1. git checkout feature-branch

If you got a failure at this step you can safely delete those
temporary dangling files and then follow the advice given by
`git status`.
Typically it'll list files with conflicts. Open them with
your $EDITOR, resolve conflicts like normal, and add the
result using `git add`. Nonetheless, we'd like to get to the
bottom of this issue.

I've never ran into this myself, and it's never been reported
here so this is not a known issue.
It's still safe to proceed with the merge and resolve files the
normal way. If you would rather undo the rebase and go back to
your original state (before the rebase) then you can do
`git rebase --abort` anytime.
I'm not sure about a workaround, but.. it might possibly work if
you were to `mkdir -p` the directory mentioned above, but that's
a guess. If that does workaround the issue then please let us
know since that would be an interesting data point.

Thanks for the thorough response. Here is some basic info:
$ git --version
git version 2.5.0
$ cat /etc/issue
Ubuntu 15.10
$ git config merge.tool
kdiff3
The issue seems as if it may be related to different renames of the
same file/folder in both the master branch and the feature branch.
I have a minimal repro in a repository located here:
https://github.com/royaldark/git-mergetool-issue
The repository has 2 branches, master and feature-branch. There are 3
commits: the initial commit, an additional commit on master, and a
commit on the feature branch. The initial commit has a folder named
"a" with a text file in it. The commit on the feature branch renames
that folder to "b", and the second commit on master renames it to "c".
Both commits modify the text file in the folder.
To repro the issue,
1. Clone the repo
2. git checkout feature-branch
3. git rebase master (or git merge master, either way works)
4. git mergetool
This produces errors like the following:
mv: cannot stat ‘a/b.txt’: No such file or directory
cp: cannot stat ‘./a/b_BACKUP_32417.txt’: No such file or directory
mv: cannot move ‘.merge_file_EYnyGH’ to ‘./a/b_BASE_32417.txt’: No
such file or directory
/usr/lib/git-core/git-mergetool: 229: /usr/lib/git-core/git-mergetool:
cannot create ./a/b_LOCAL_32417.txt: Directory nonexistent
/usr/lib/git-core/git-mergetool: 229: /usr/lib/git-core/git-mergetool:
cannot create ./a/b_REMOTE_32417.txt: Directory nonexistent
As for your thoughts on a workaround, you were exactly right:
I'm not sure about a workaround, but.. it might possibly work if
you were to `mkdir -p` the directory mentioned above, but that's
a guess. If that does workaround the issue then please let us
know since that would be an interesting data point.
The following steps do NOT cause the issue:
1. git checkout feature-branch
2. git rebase master (or git merge master, either way works)
3. mkdir a
4. git mergetool
Creating the "a" directory solves the issue, and git-mergetool runs
without error.
Please let me know if I can provide any additional information.
