Perforce will mark files as readonly when it does a checkout. When you use `p4 edit` to say you have made changes to the file, Perforce removes the readonly bit. What is happening here is that the sync (checkout) command is trying to write foo.h/c to your build_scripts directory, but because they already exist there *and* are not readonly, Perforce is producing that error as it does not want to overwrite any files that have changed locally. Not sure what is happening on the git-p4 side, though. - Reece ``` ## Gary Yang, 2008-12-03 00:14 Subject: Re: git-p4 submit, Can't clobber writable file Message-ID: <94261.93438.qm@web37908.mail.mud.yahoo.com> URL: https://gitlist.dev/e/94261.93438.qm%40web37908.mail.mud.yahoo.com In-Reply-To: <3f4fd2640812021551t5451e6e3i91e6d2694c89e085@mail.gmail.com> ``` Reece, I understand your explanation.

You might want to clone to a git working dir different than the p4 working dir. For instance, if your p4 workspace has the working dir set to build_scripts/, try 'git p4 clone //build/scripts build_scripts.git'. You would then normally work under build_scripts.git/. build_scripts/ would only be used by git-p4 at submission time.

When you do 'git p4 submit', it basically: 1. calls 'p4 sync' in the p4 working dir, 2. generates patches from p4/master..HEAD, 3. for each of the patches, applies it in the p4 working dir, and 'p4 submit' it as one changelist. > Then, p4 submit code into > Perforce. Is this the only way of using git-p4? Note: I cannot use > git-p4 submit at build_scripts. It claims "Cannot clobber writable > file". Is it a bug of git-p4 or the instruction is not correct? Git-p4.txt does mention this (although briefly) in the "Submitting" section: "git-p4 has support for submitting changes from a git repository back to the Perforce depot. This requires a Perforce checkout separate from your git repository..."

The doc should clearly state that we need a separated P4 working dir in order to make git p4 submit work. Many thanks to Jing.
