-----------------------------------
Summary: c proactor listening behavior
Key: PROTON-1438
URL: https://issues.apache.org/jira/browse/PROTON-1438
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
Improved listening behavior for pn_proactor_listen to allow selective listening
by protocol (ipv4/v6) or portable "listen to everything".
Host can be a host name, IPV4 or IPV6 literal,
or the empty string/NULL (treated the same). The empty string listens on all
local addresses. A host name listens on all addresses associated with the name.
An IPV6 literal address (or wildcard '[::]') listens only for IPV6. An IPV4
literal address (or wildcard '0.0.0.0') listens only for IPV4.
- pn_proactor_listen may listen on more than one socket for ipv6/v4 or
for DNS names with multiple address records.
- the 'backlog' applies to *each* socket (open for debate - we might
want to divide the backlog among sockets with some minimum if there's
not enough)
- pn_listener_close() closes all sockets, PN_LISTENER_CLOSE event
indicates all sockets are closed.
- An error on any socket will close all the sockets of the listener,
PN_LISTERN_CLOSE event indicates all sockets are closed and provides
the error that triggered the close.
