Which version of p4 are you using?

Your suggested fix looks plausible though. Possibly it needs both
chdirs() so that "p4 sync" will work if the caller is using a
.p4config file in the p4 client directory to set the P4CLIENT.

Thanks!

In that case, I have cc'd Luke and Lars, who work on p4

I debugged the issue using the script here:
https://github.com/git/git/blob/master/git-p4.py
I'm not sure how close to the main repo that is.

Do you use the Git as provided from OS X? In that case you better report the bug
to Apple, as their version of Git is slightly different (not close on
upstream, by both
having additional patches as well as not following the upstream closely IIUC).

BUG on OSX `git p4 submit` can fail when the workspace root doesn't exist locally.

[Jacob Smith]

On OS X, if the local p4 workspace root doesn't exist, then git-p4 can
fail on submit. The error message looks like this:

Synchronizing p4 checkout...

Git submit failed!
shell-init: error retrieving current directory: getcwd: cannot
access parent directories: No such file or directory
fatal: Unable to read current working directory: No such file or directory
Command failed: ['git', 'rev-list', '--no-merges',
'remotes/p4/master..master']

The problem is in the function 'run()' around line 1957. The logic in
the code is:

1. Detect if the clientPath exists;
2. If the clientPath doesn't exist, set the 'new_client_dir'
variable to 'True';
3. chdir() to the clientPath; then,
4. If 'new_client_dir' is 'True', then p4_sync("...", True).

On my system, the call to `p4 sync -f` leaves the clientPath directory
that git-p4 had chdir()'d into an orphan, so the call to 'git rev-list
...' a few lines fails because the call to getcwd() fails (the
directory has no parents).

I can make the problem "go away" by moving the location of the call to
'chdir(self.clientPath, is_client_path=True)' after the call to
`p4_sync()`, but I'm not sure if that's really fixing the issue, or
not.

Thanks!
-j.
