[OpenSIPS-Devel] [opensips] OpenSIPS 1.8.4 can not be started when there are dialogs in the dialogs table (#197)

Hello,

In my tests, the crash no longer occurs with the provided commit.

The underlying issue is that, indeed, the cachedb_sql module does not properly implement the cachedb interface - it manages it's own global connection to the back-end instead of allowing the interface to do it ( this is a side effect of the fact that the module was implemented following the cachedb_local template where there is no actual connection ).

For a full example of the way the interface was meant to work, please take a look at the cachedb_redis ( eg. the init function from the cachedb interface should actually create the connection to the backend , instead of creating the connection in the mod_init func of the back-end module. Further on, that connection can be retrieved when running a command by accessing the cachedb_con->data pointer ).

Best Regards,
Vlad
