[sr-dev] [kamailio/kamailio] sqlops offline database start and live re-connect (#1681)

[Henning Westerholt]

The issue here is that the sql_connect() bind and initialize the internal database handle structure. If this is not properly done, the module can't operate later on the database. If you want to implement a change like this, I would suggest to dig a bit deeper in the code.

One idea would be to periodically trigger (e.g. with a timer) a check if the DB got available, and then initialize it properly. Probably also necessary would be a protection of every DB access with a lock, to prevent errors during the initialization (because of the Kamailio multi-process architecture).
 
If you are interested in digging into that feel free to discuss your approach on our sr-dev list. If you managed to get a first working version, then just open a pull request for a review.
