Subject svn commit: r1694249 - /subversion/trunk/subversion/libsvn_subr/stream.c
Date Wed, 05 Aug 2015 15:28:31 GMT
Author: stefan2

New Revision: 1694249

URL: http://svn.apache.org/r1694249
Log:
Fix a limitation in our svn_stream_skip fallback implementation found while
playing around with stream wrappers:  Some streams don't implement read_full,
others don't implement the normal read. Make the fallback code work in either
case.

Note that this is not a problem for any of our currently used stream
implementations.

* subversion/libsvn_subr/stream.c
  (svn_stream_skip): Our default implemenation for skip will work with any
                     read function.  So, fall back to any read function
                     that the stream actually implements.
