Subject svn commit: r1378634 - /subversion/trunk/subversion/libsvn_ra_serf/update.c
Date Wed, 29 Aug 2012 16:36:26 GMT
Author: cmpilato

New Revision: 1378634

URL: http://svn.apache.org/viewvc?rev=1378634&view=rev
Log:
Finish issue #3993 ("serf corrupts wc by calling close_edit for an
incomplete update-report").

* subversion/libsvn_ra_serf/update.c
  (report_context_t): Add 'report_completed' flag.
  (end_report): Toggle the new 'report_completed' flag once we've seen
    the closing update-report tag.
  (finish_report): Only call the update editor's close_edit() if we
    saw the closing update-report tag; otherwise, raise an error.
