Subject svn commit: r1655354 - in /subversion/trunk/subversion: mod_dav_svn/repos.c tests/cmdline/commit_tests.py
Date Wed, 28 Jan 2015 14:47:50 GMT
Author: rhuijben

New Revision: 1655354

URL: http://svn.apache.org/r1655354
Log:
Resolve issue #2295, by making mod_dav produce an svn specific error report
on MKCOL requests that hit an existing resource during commit.

* subversion/mod_dav_svn/repos.c
  (prep_working): When parsing for mkcol, break out early.

* subversion/tests/cmdline/commit_tests.py
  (mkdir_conflict_proper_error): New test.
  (test_list): Add mkdir_conflict_proper_error.
