Re: [sr-dev] extension of DMQ module to support several notifcation servers

Hello, thank you both for the reply. So, it seems that option 2) seems to be the preferred way. We will investigate this then and if necessary, update this discussion.

Now you will be asked to support both :) On Mon, Oct 5, 2020 at 8:38 AM Daniel-Constantin Mierla <miconda@gmail.com<mailto:miconda@gmail.com>> wrote: Hello, the problem I see with 1) is in case one wants to set there SIP URI for other transports than UDP, the ; is used to separate URI parameters as well. I think now it supports only UDP anyhow, but to have it open for future, this should be kept in mind From my point of view, for the modules I work with and develop, the style of separating with ; within same modparam value suits for sip-params-like-values, respectively name1=value1;name2=value2; ... because parase param function can be used. In this case, a value can contain ; but the entire value has to be enclosed in quotes. So far 1) maybe another delimiter between URIs should be used, like comma. Personally I would like more for 2), it is more compact in case one uses many addresses, not to have a single very long value, but I don't really mind 1) with a different separator (at the end both variants can be supported :-) , but more coding is needed, without much benefits ...)

Right now the module supports only one server in the notification_address parameter. It is possible to set multi_notify to 1, and then the module will resolve the one sip URI over DNS to multiple servers, thought. There is interest in extending the module to support multiple notification_address servers natively without using DNS. I see two options right now: 1. Separate the multiple servers, with “;”, e.g. modparam(“dmq”, “notification_address”, “sip:server1;sip:server2”). If only one server in the param, use the existing logic. 2. Use multiple notification_servers parameter calls, e.g. modparam(“dmq”, “notification_address”) - modparam(“dmq”, “notification_address”, “sip:server2”). If only one param statement, use the existing logic. As the module already has support to use a notification server list internally, the change should be small in both cases. I think option 1) is the better way, as its already done in other modules like this to support multiple server scenarios. Any comments or objections about this extension?
