Description From Jaime Frey 2007-01-23 23:09:13

I've found a file that causes globus-url-copy to fail when transferring it from
a local file to a remote gass server. globus-url-copy exits with status 1 and
prints this:

error: [globus_l_gass_copy_gass_write_callback]: gass_transfer_request_status:
3

I see this when using globus-url-copy and globus-gass-server from Globus 4.0.3
with and without the globus_gass_transfer-2.11 advisory applied.

I tested this a bit with the test file with globus-url-copy and with another
http client. This appears to be a server HTTP parsing error causing a premature
connection close on the server side.

Patch  to globus_gass_transfer

Attaching a patch to globus_gass_transfer which seems to fix the issue. I think
the HTTP specification is a little vague on whether chunk extension parsers are
supposed to accept linearize whitespace after a chunk size token. This code
change affects the parsing in the case a chunk begins with a tab followed by a 
semicolon.

I can confirm that the patch fixes the problem in transferring this file.
