[PATCH 2/3] git-p4: [usability] RCS Keyword failure should suggest help

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Ben Keene <seraphire@xxxxxxxxx>

When applying a commit fails because of RCS keywords, Git
will fail the P4 submit. It would help the user if Git suggested that
the user set git-p4.attemptRCSCleanup to true.

Change the applyCommit() method that when applying a commit fails
becasue of the P4 RCS Keywords, the user should consider setting
git-p4.attemptRCSCleanup to true.
