Description Tim Waugh 2013-06-26 13:58:28 UTC
Description of problem:
When using IPP/2.0 (from e.g. Fedora 19), a bug in the IPP writing code for 'collection' attribute types can cause incorrect data to be sent back in response to, for example, a printer attributes query.

In particular, the IPP data sent is shorter than the HTTP Content-Length header advertises, causing the IPP/2.0 client to wait for the rest of the data and, since it is not forthcoming, time out.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.From Fedora 19: lpstat -h theserver/version=2.0 -s

Actual results:
60s delay for each IPP request.

Expected results:
No delay.
