svn commit: r1768311 - in /subversion/trunk/subversion: include/svn_ra.h libsvn_client/list.c libsvn_ra/ra_loader.c

[st...@apache.org]

Author: stefan2

New Revision: 1768311

URL: http://svn.apache.org/viewvc?rev=1768311&view=rev
Log:
Use the correct error code to signal that a server does not implement
svn_ra_list.

* subversion/include/svn_ra.h
  (svn_ra_list): Explicitly document the error code that can be expected.

* subversion/libsvn_ra/ra_loader.c
  (svn_ra_list): Return "feature not supported" instead of "entire protocol
                 scheme not supported".

* subversion/libsvn_client/list.c
  (list_internal): We now only need to test for one error condition.
