_GNU_SOURCE

by Juha Heinanen

daniel, thanks for your reply. i started a new thread on _GNU_SOURCE. tcp_main.c includes io_wait.h, which in turn defines _GNU_SOURCE: #define _GNU_SOURCE /* for POLLRDHUP on linux */ _GNU_SOURCE is also included by tls module, which can be considered to be part of "core": #define _GNU_SOURCE 1 /* Needed for strndup */ is it possible to get rid of these two _GNU_SOURCE dependencies? if not, then _GNU_SOURCE version of memmem can be freely used in all modules and we can get rid of ser_memmem. --- juha

rfc: evapi architecture and message format

by Daniel-Constantin Mierla

Hello, (cross-posting because the results are impacting users) recently I added a new module named evapi: - http://www.kamailio.org/docs/modules/devel/modules/evapi.html The purpose is to able to send custom messages to applications that connect to kamailio via tcp on a special port (different than sip port) as well as receive messages and react on them. One of the first use case we look at is integration with cgrates for real time billing. For example: - send notification when a new call comes in and cgrates will return allow/reject - send notification when the call starts so cgrates can start billing - send notification when the call ends so cgrates will close bllling The module is now in quite good shape, sending and receiving messages. Sending is done from config file, in the future some modules might do it from inside. Received message is passed to config file via an event_route and variables. Now, the point of this discussion is to debate following points: 1) should there be a specific format used for this messages? The examples in the README use json. The module can encapsulate them in netstring format when sending over tcp to be easy to parse and read the message at once. This is optional, the message can be sent as it is 2) now messages are sent to all connected applications, should be there some subscription mechanism per event? If yes, then there has to be a way to specify the event, so point 1) might need a specific format 3) handle response - should be there a defined api that will say allow, reject, drop? I was thinking that the return could be some script for an embedded interpreter (e.g., Lua) that can be executed from config file. Or, alternative, manually scripted in the event route, so each user defines its own api 3) other suggestions for what should be discussed? Looking forward to opinions regarding these matters. Cheers, Daniel -- Daniel-Constantin Mierla - http://www.asipto.com http://twitter.com/#!/miconda - http://www.linkedin.com/in/miconda
