Description From Jaime Frey 2007-03-12 11:16:09

If you call a gram client library function with a jobmanager contact string
that doesn't have a path, the library segfaults. The problem is in
globus_gram_protocol_frame_request(), which assumes that if globus_url_parse()
returns GLOBUS_SUCCESS, then globus_url_t.url_path will be non-NULL. That's not
true for URLs like https://gate02.grid.umich.edu:40041.

You can reproduce this using globusrun:

globusrun -status https://foo.edu:40041

This problem is currently affecting Condor-G. A rare bug in Condor-G causes
some jobmanager contact strings to be truncated. When this bug occurs, the gram
bug described here exacerbates the problem. We are working on finding the
Condor-G bug, but it's tricky to track down.

Patch to GRAM Client / Protocol libraries

Attaching a patch which avoids the crash and returns an invalid contact error
when the contact URL does not contain a path.

I applied the patch and the crashes ceased. Now, the functions return gram
error 80 as expected.

Fix applied to 4.0 branch and trunk.
