[PATCH v4 2/3] git-svn: enable "svn.pathnameencoding" on dcommit

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

 



From: Kazutoshi Satoda <k_satoda@xxxxxxxxxxxxx>

Without the initialization of $self->{pathnameencoding}, conversion in
repo_path() is always skipped as $self->{pathnameencoding} is undefined
even if "svn.pathnameencoding" is configured.

The lack of conversion results in mysterious failure of dcommit (e.g.
"Malformed XML") which happen only when a commit involves a change on
non-ASCII path.

[ew: add test case to t9115,
 squash LC_ALL=$a_utf8_locale export from Kazutoshi for Cygwin]
