Review Request 22812: Broker recovery forgets auto-delete flag on queues and exchanges

-----------------------------------------------------------

Review request for qpid, Ernie Allen, Justin Ross, and Kim van der Riet.


Bugs: QPID-5835
    https://issues.apache.org/jira/browse/QPID-5835


Repository: qpid


Description
-------

Simple extension of [Exchange|Queue]::[encode|restore] by adding boolean as int8_t at the end of the buffer. Should be backwards compatible.

There is one question how queue node with auto-delete:True _and_ auto-delete timeout set should be recovered: should be the timer ticking or not? Currently implemented option is the timer is not running: as we dont know if the queue had a consumer before restart, let be conservative and think it hadn't.

But this might cause queue leak in scenarios like "create auto-delete queue with timeout, subscribe to it, restart broker, dont re-subscribe there"


Diffs
-----

  /trunk/qpid/cpp/src/qpid/broker/Exchange.cpp 1603448 
  /trunk/qpid/cpp/src/qpid/broker/Queue.cpp 1603448 

Diff: https://reviews.apache.org/r/22812/diff/


Testing
-------

Automated tests passed, manual tests show JIRA is fixed by the patch.


Thanks,
