[PATCH v1] git-p4: fix git-p4.pathEncoding for removed files

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

 



From: Lars Schneider <larsxschneider@xxxxxxxxx>

In a9e38359e3 we taught git-p4 a way to re-encode path names from what
was used in Perforce to UTF-8. This path re-encoding worked properly for
"added" paths. "Removed" paths were not re-encoded and therefore
different from the "added" paths. Consequently, these files were not
removed in a git-p4 cloned Git repository because the path names did not
match.

Fix this by moving the re-encoding to a place that affects "added" and
"removed" paths. Add a test to demonstrate the issue.
