Hello,
Even if we have agreed on meeting in Glasgow sometime between the 21rst
and the 23rdf of August, I would like us to establish a plan for
migrating to 0.10. I have added a list of tasks for migrating to 0.10
(it is based on what Gordon has done for C++). It would be nice to put
estimate on those tasks and also to allocate them to people (note that
some tasks may be missing). More generally it would be good to know what
people involvement for the 0.10 migration is.
==model:==
* new query methods for exchange and binding (and possibly queue)
* minor changes to method arguments etc
- separation of 'auto-delete' from 'exclusive' in queue.declare
- removal of responses and no-wait field from several methods
- 'reject-unroutable' flag
* new flow control for message transfer
* new acking method for deliveries
* dtx - expose basic functionality through client
* changes to encoding of transfer
==execution layer:==
* track execution mark for outgoing requests
* manage execution mark for incoming framesets
* generic correlation support (details still vague)
==session layer:==
* session abstraction
- Channel should be Session
- channel exceptions are now session aborts
- channel open and close should be altered
- ack and hwm exchange
* session management
- maintain map of detached sessions, with timeouts
- simple case: sessions destroyed on detach
- failover: re-attach session to a channel on a new connection
- manage requested timeout
* replay buffer management
- record all outgoing frames along with a sequence number
- on receipt of an ack, delete as appropriate
* session re-establishment & replay
- implement session resumption (broker side only)
- re-establish connection (client side only)
- send any frames not seen by peer
==framing:==
* new field table encoding (including lots of new value types)
* new uuid type
* new type for 'long sets' (for ack structures)
* revised frame encoding
* decoding from (& encoding to?) discontinuous data
* revised architecture (chains, assembly of segments & framesets,
memory management etc)
