Are you talking specifically about something at the c level rather than
e.g. c++?
As far as I recall, the c layer has no built in support for
reconnection, that is added by the c++ (or other) wrappers.
In the c++ api, perhaps the reconnect options in use could be exposed
(such that they can then be altered), or else there could be a way to
provide a function that returns the next url to use rather than a static
list (this is sort of what the python wrapper allows). That may be what
you mean by the onReconnect callback? If so, it sounds reasonable to me,
though it would be better to get the thoughts of those more involved
with that component. (Alan, Cliff, Andrew?)

Subject: RE: [Proton-C] Discovery
Hello,
We looked into the proton-c implementation and didn't find anything that would
allow us to implement a qpid-jms like discovery.
So I was wondering if we could add, directly in proton-c, an onReconnect
callback (or something similar) that would allow us to modify the list of URLs
the client tries to connect to.
We need this to answer the following use case:
the dispatch-router (host1:1234) on which the client was connected goes down
the client enters the reconnect loop (on host1:1234)
we restart the dispatch-router but on another machine (host2:5678)
the client reconnects -> this is currently not happening
Note that we can do the pull-request but I wanted to run the proposition by you
first.
Thanks,
Olivier

Subject: [Proton-C] Discovery
Hello,
I was looking into the qpid-jms-discovery project which seems very nice for
what I'm trying to do: update the list of dispatch-routers the client can
connect to during failover (with a custom discovery logic).
I wanted to know if there is something similar with proton-c or at least a way
for me to implement it?
Thanks,
Olivier
