Ah, sorry, I misread the player_alloc stuff.

Thanks for the comments! I will change the patch accordingly.

Could you help me to find the place there default ai player_alloc is called?

The calling structure is:
ai->funcs.player_alloc
. => lai_player_alloc (lai_func.c)
.. => player_set_ai_data (using struct lai_plr *luaplr as ai data)
.. => lai_api_player_alloc (api_lai_base.c)
... => dai_data_init

First data handling error I notice:

luaai player_alloc allocates memory and stores it to player structure. But default ai player_alloc gets called too, overwriting the pointer.

- Build system needs to handle luaai as independent type. Now it seems to depend on how threaded ai is configured.
- Increase of maximum number of simultaneous AI types is separate change which should not be part of this patch.

I reworked the lua ai patch. At the moment it can be activated (use ./fcser -L lua) and runs without crash or errors. But, the lua AI does not really moves its units etc. Thus, help is needed!

I suspect the error in the area of data handling. The AI functions use arguments which are not handled in the default lua name space. Remembering the calling flow:

<server> => LuaAI function => call to lua => callback to C => default AI

the arguments (pointers) have to be 'tunneled' throw lua. I use a 'dummy' data type lai_data for this. It 'transports' the pointer via the lua environment. I'm not sure if this is the corret way to go ...

I've skimmed through the whole patch, and I have to say that it looks promising. I hope you can commit this soon (As a general note, I personally don't like your habit of committing huge patch series at once - while you keep individual patches manageable small, committing them at once does not really give me possibility to look them one small bit at a time. I usually end up checking only first patch of the series. I'd much prefer you committed first patches of the series once they are ready and you're still working on latter ones)

Looked just configure stuff, and that at least is not at all correct. Search ai/Makefile.am and configure.ac for word "threaded" to see how enabling/disabling static/dynamic threaded ai is implemented.

updated version - it (kind of) works:

- all callbacks are implemented but do nothing at the moment

Well, finishing of default ai code refactoring is still week or two away since I were absent for a while. I'm not only posting to repeat over and over that we are still a week away from completion. Progress has been made, and now all the patches have already been made (they still need fixing, but at least we have tickets to follow now). Remaining ones are patch #2692, patch #2693, patch #2694 and patch #2286

In any case I think we should finish refactoring of default ai code before lua ai module stuff starts to go in. I don't want latter to postpone former by adding complexities. Default ai work is more than our internal cleanup (of default ai itself). It gives clear base to build other ai modules, and I actually consider it a requirement for any custom ai module.
Default ai refactoring is quite close to completion. This means. scale of the project being that I started it almost two years ago, that we should be just a couple of weeks from the point where it can be considered done.
