Re: [SR-Users] No "child_destroy" export - issue with module flatstore and flush=0

Hi Nicolas, the module API could be changed of course, so far it was not needed as the module needs could be covered in the current API version. What kind of errors are you observing, some race conditions or similar?

For the record, I'm using Kamailio module "flatstore" with the flush deactivated. In this situation, when Kamailio is stopped, I'm losing the remaining data in files not yet flushed. So my idea was, when destroy is called, to iterate over the connection pools, and flush/close all the opened files properly. But I found out that it's not that simple :/ Do you think this is something that could be fixed in Kamailio ? Regards, Nicolas.

Hi Nicolas, you are right, there is no special function for children destroy. Most modules do not need it, as the data is in shared memory, processes are started over standard kamailio APIs which will be stopped from the core automatically, to give some background. Some modules do it by just iterating over an internal list of their children and then do the cleanup task. You can find an example in cdp module (destroy, diameter_peer_destroy).

Hello, I have a module, for which I need to perform some processing in the children processes when Kamailio is being stopped. I've looked at the "struct module_export", in which I see "mod_init", "child_init", "mod_destroy"... but no "child_destroy". :/ Is there a way to achieve this ? Thanks for your help.
