svn commit: r1499727 - in /subversion/trunk/subversion:
libsvn_ra_svn/client.c libsvn_ra_svn/protocol svnserve/serve.c
Author: danielsh
Date: Thu Jul 4 11:45:20 2013
New Revision: 1499727
URL: http://svn.apache.org/r1499727
Log:
Follow-up to r1498550: widely document the implementation detail that r1498550
relies on, and elevate it to a protocol promise.
No functional change (comment changes only).
Suggested by: philip
* subversion/libsvn_ra_svn/client.c
(ra_svn_commit): Extend documentation of the LOG_MSG manipulation.
* subversion/libsvn_ra_svn/protocol
(commit):
Specify the behaviour of the server when both LOGMSG and REVPROP-TABLE are
present. I verified (by code inspection) that 1.5.x@HEAD behaves that way,
so presumably everything in [1.5.0, trunk@HEAD].
* subversion/svnserve/serve.c
(commit): Point to the new protocol promise.
