I wonder why gerrit did not flush the draft messages... Hopefully it works this time. https://gerrit.osmocom.org/#/c/5881/9/include/osmocom/mgcp_client/mgcp_client_fsm.h File include/osmocom/mgcp_client/mgcp_client_fsm.h: Line 11: * > naming is not clear enough "conn_info" sounds like some generic information "peer" sounds good to me. The call-id and the endpoint in that struct are debatable. For the CRCX when I use the struct as input parameter I need to supply an endpoint-id and a call-id. When I get the response. I might be interested in the endpoin-id the MGW actually supplied, so I need this parameter there too. I might not necessarily need the call-id since I already know it, but we can echo it here as service for the user so he does not need to memorize it. If the endpoint-id was already specific, than its the same for the endpoint-id Trouble starts when it comes to an MDCX. Then I definitely do not need to supply a call-id or a connection-id. The FSM knows this by itself. So in this case its not entirely clear. The only way I see to resolve this is to have separate structs for each case, but this also would complicate the API then. https://gerrit.osmocom.org/#/c/5881/9/include/osmocom/mgcp_client/mgcp_client_internal.h File include/osmocom/mgcp_client/mgcp_client_internal.h: Line 32: struct mgcp_client *mgcp, > unrelated whitespace change?

When we terminate regularly (OSMO_FSM_TERM_REGULAR) the cleanup is executed, right? I was thinking about an unconditional DLCX in case of error situations, we could do this, but I think it does not make too much sense. Normally errors occur because the MGW times out. This usually means that the MGW is down. Sending a DLCX in those situation does not make too much sense. Thats why I skipped this. If we want to implement the unconditional DLCX anyway, we could go by the cause code to distinguish clean exists from unclean ones. Line 511: .name = "MGCP_CONN", > I think it's not a client FSM, but a client connection (or mgcp connection I have renamed it now, but I think the other namings should stay as they are, there is already the "mgcp_client" and with "mgcp_client_fsm" I want to express the close relationship between the two. -- To view, visit https://gerrit.osmocom.org/5881 To unsubscribe, visit https://gerrit.osmocom.org/settings Gerrit-MessageType: comment Gerrit-Change-Id: I887ce0c15a831dffeb6251a975337b83942af566 Gerrit-PatchSet: 10 Gerrit-Project: osmo-mgw Gerrit-Branch: master Gerrit-Owner: dexter <pmaier at sysmocom.de> Gerrit-Reviewer: Harald Welte <laforge at gnumonks.org> Gerrit-Reviewer: Jenkins Builder Gerrit-Reviewer: dexter <pmaier at sysmocom.de> Gerrit-HasComments: Yes
