Subject svn commit: r1150841 - /subversion/trunk/subversion/libsvn_auth_gpg_agent/gpg_agent.c
Date Mon, 25 Jul 2011 18:45:58 GMT
Author: stsp
Date: Mon Jul 25 18:45:57 2011
New Revision: 1150841

URL: http://svn.apache.org/viewvc?rev=1150841&view=rev
Log:
* subversion/libsvn_auth_gpg_agent/gpg_agent.c
  (password_get_gpg_agent): We can pass the full BUFFER_SIZE to
   receive_from_gpg_agent() and send_option() because they will
   NUL-terminate. (Historically these were arguments to recv() and
   send() which do not.)
