Issue #2154 - svn blame to error out gracefully given a directory

From: VK Sameer <sameer_at_collab.net>
Date: 2005-02-23 11:24:32 CET


I have a couple of questions about this issue

While debugging this, verbosity on the client side could be increased
with neon_debug_mask. What is the equivalent on the server side?
Alternatively, not having delved enough into the code, any pointers to
the area to instrument to find out what goes over the wire from the
server end? Looking at an Ethereal trace doesn't give all of the info
contained in this error message:

subversion/libsvn_ra_dav/util.c:682: (apr_err=175002)
svn: REPORT request failed on '/repositories/blame_tests-3/!svn/bc/1/A'
subversion/libsvn_ra_dav/util.c:668: (apr_err=175002)
svn: The REPORT request returned invalid XML in the response: XML parse
error at line 1: Extra content at the end of the document
. (/repositories/blame_tests-3/!svn/bc/1/A)

The error messages show up in the httpd server logs, but don't get sent
over the wire.
dav_svn__file_revs_report() does generate the correct error message and
a status of 500. I don't understand all the details, but it looks like
it is not possible to modify the header at that point. Can this be put
into the HTTP packet's body as an xml error message?

There also seems to be an inconsistency in the way dav_svn_convert_err()
handles error messages:

     derr = dav_new_error_tag(pool, status,
                              serr->apr_err, apr_pstrdup(pool,
     if (message != NULL)
         derr = dav_push_error(pool, status, serr->apr_err,
                               message, derr);

As currently implemented for this issue, message and serr->message are
both NULL (and in fact message = serr->message). There is no check for
NULL before calling apr_pstrdup(). Is this a problem?
