Hello all

I'm starting to play with lua scripting in Kamailio. It's really cool, some complex stuff in the script becomes really easy this way. The script is becoming quite big, therefore I'd like to use lua_run instead of lua_dofile. My doubt is pretty basic: if i load a script in memory at startup via the "load" parameter and the script is modifed afterwards, is there any way to reload the module so the script is reread?

the two contexts created by app_lua were designed one for loading at startup and the other for reloading every time. Reloading on demand at runtime is not possible. I thought of checking the timestamp of the script, but can be a bit risky if saving on intermediary state during updates. The scripts are loaded in each process, sending a mi/rpc command will require to do some inter-process signaling. Both doable, not in my short term plans, though, if someone is contributing, will be appreciated.

Understood, we may give it a try in the next weeks.

Some options for speed up with existing code:
- you can compile the Lua scripts, so reloading it each time will be faster (no more compile on-the-fly)

I agree it's the most logical approach.

- not sure about this one: in your script loaded at startup you may have some logic to load another script based on your rules (e.g., file timestamp, periodically, ...)

Not sure either, will try.

What about using luajit?
