-----------------------------------
Summary: Change proactor ownership model
Key: PROTON-1445
URL: https://issues.apache.org/jira/browse/PROTON-1445
Project: Qpid Proton
Issue Type: Improvement
Components: proton-c
Affects Versions: 0.17.0
Reporter: Alan Conway
Assignee: Alan Conway
Fix For: 0.18.0
Change ownership model for pn_connection_t and pn_listener_t managed by the
proactor: instead of proactor freeing automatically after the final event, the
user must free on or after the final event.
There are 2 basic use cases:
1. Free connection/listener immediately on the last event.
2. Keep connection/listener in memory until all application pointers are
cleaned up.
Proactor ownership does 1. very well, but makes 2. very difficult without
exposing reference-counts.
User ownership supports both reasonably easily: 1. is implemented by calling
pn_connection_free() or pn_listener_free() in the event handler on the last
event.
