You've changed the part where git-p4 reads the submit message back from the text editor. There has been no interaction with p4 yet. The self.isWindows check after your changes is just to remove "\r" from newlines that many windows editors produce. Now could be that you're worried not about this message, but about failing in the later apply when it tries to put the "\n"-terminated patch onto a workspace full of "\r\n". There was a recent thread: http://thread.gmane.org/gmane.comp.version-control.git/221664/focus=223625 suggesting that core.autocrlf was to blame. Would be interesting if this turns out to be your problem too. Maybe we could look for that and do something sensible. The other thing to check is "p4 client -o" and see what LineEnd setting exists for the backing p4 workspace. -- Pete > From aef963f0c45dea81f3e6f30d3b4185a0983ca4de Mon Sep 17 00:00:00 2001 > From: David Foster <davidf...@gmail.com> > Date: Mon, 6 May 2013 10:50:01 -0700 > Subject: [PATCH] Compensate for Windows-style output from the p4 command on > non-Windows systems. > > --- > git-p4.py | 18 ++++++++++++++++++ > 1 files changed, 18 insertions(+), 0 deletions(-) > > diff --git a/git-p4.py b/git-p4.py > index 647f110..949d66d 100755 > --- a/git-p4.py > +++ b/git-p4.py > @@ -1454,6 +1454,24 @@ class P4Submit(Command, P4UserMap): > tmpFile = open(fileName, "rb") > message = tmpFile.read() > tmpFile.close() > + > + # HACK: If Perforce spontaneously generates Windows-style output, > + # compensate by assuming the entire p4 command went into > + # Windows mode. > + if separatorLine not in message: > + print "WARNING: Perforce has spontaneously decided to > generate Windows-style output.
