I'm looking into a piece of logic for extracting basic information about a working copy (basically, the output of `svn info` on the the current directory or on the wc root), and trying to teach it to detect the situation "This is a working copy, but I can't read it".
What error codes should I look for? In a few test cases I managed to get straight `svn info` to report SVN_ERR_WC_UPGRADE_REQUIRED, SVN_ERR_WC_UNSUPPORTED_FORMAT, and SVN_ERR_WC_CORRUPT on the one hand, and SVN_ERR_WC_NOT_WORKING_COPY on the other hand, and I'm sure there are more... Thanks, Daniel
