Steven Hardy created QPID-4583:
----------------------------------
Summary: python-qpid limits map element size to 65535 bytes
Key: QPID-4583
URL: https://issues.apache.org/jira/browse/QPID-4583
Project: Qpid
Issue Type: Bug
Components: Python Client
Affects Versions: 0.20
Environment: Tested on Fedora 17, python-qpid-0.20-1.fc17.noarch
Reporter: Steven Hardy
It seems that we hit a limit of 65535 bytes when encoding a map via
python-qpid, because the map elements are encoded as a str16 (write_map in
codec010.py)
Looking at the amqp 0-10 spec, it says "An encoded map may contain up to
(4294967295 - 4) octets worth of encoded entries.", and I don't see any
specified limit for individual map elements. This limitation does not appear
to exist when testing on rabbitmq, so I'm wondering if it's possible to work
out a way to remove this limit when using qpid.
