Description:

• Unable to overwrite function compiled (PREP/CBA_fnc_compileFunction) by CBA while using cba_cache_disable.pbo. After reviewing the current version of CBA_fnc_compileFunction it appears this line should've been changed to use compile instead of compileFinal https://github.com/CBATeam/CBA_A3/blob/master/addons/xeh/fnc_compileFunction.sqf#L34 although I'm not sure is problem as I'm not too familiar with this code. I also feel that I should be able to disable the compileFinal calls without completely disabling the function caching feature, that being said I could resolve that on my own by making my own pbo that changes the CfgSettings >> CBA >> Caching >> compile value to 0 without messing with any of the other variables. What I am attempting to do is build an addon that overwrites some internal functions inside of ACE3 but due to ACE3's use of CBA_fnc_compileFunction I am unable to change the function.

Steps to reproduce:

• Added cba_cache_disable.pbo to cba addons and verified CfgSettings >> CBA >> Caching values reflecting changes made by pbo.

• Created a new singleplayer mission, placed Rifleman unit down and started mission preview.

• Opened escape menu and started typing in required variables for test scenario

• Added the following to the watch variable boxes

  • dev_fnc_testFunc
  • uiNamespace getVariable "dev_fnc_testFunc"
  • missionNamespace getVariable "dev_fnc_testFunc"

• Ran the following code via Local exec button

  • ["A3\ui_f\scripts\IGUI\RscUnitInfo.sqf", "dev_fnc_testFunc"] call CBA_fnc_compileFunction

• Reviewed updated watch fields and noted that all watched variables contain:

  • #line 1 "A3\ui_f\scripts\IGUI\RscUnitInfo.sqf" which is the correct script

• Ran the following code via Local exec button

  • ["\A3\ui_f\scripts\pauseLoadinit.sqf", "dev_fnc_testFunc"] call CBA_fnc_compileFunction

• Reviewed updated watch fields and noted that all watched variables contain:

  • #line 1 "A3\ui_f\scripts\IGUI\RscUnitInfo.sqf" which is the same as before and is not desired

• I also attempted to do a variable overwrite and the change did not apply

  • dev_fnc_testFunc = compile preprocessFileLineNumbers "\A3\ui_f\scripts\pauseLoadinit.sqf"

• After reviewing RPT log I see multiple entries of:

  • Attempt to override final function - dev_fnc_testfunc

Where did the issue occur?

• Self-Hosted Multiplayer / Singleplayer / Editor (Singleplayer) / Editor (Multiplayer)

Normal:
First run compileFinal's to uiNamespace
all further runs use uNamespace version for missionNamespace (which inheritis the compileFinal)

Cache Disabled:
compileFinal's to missionNamespace each restart

So, do we want a 3rd setting that does not compileFinal at all?

Yes. In the scenario that I'm in I would like to be able to overwrite functions that are created in overpressure ACE3 addon without having to remove the existing pbo and create a copy and have to maintain version numbers and such without loosing the performance gain from caching.

[PabstMirror]

could hack in functions with something like this, define your funcs before ace runs

requiredAddons = {"ace_overpressure"};

class Extended_PreInit_EventHandlers {
    class ace_overpressure {
        init = "myInit.sqf";
               
myInit.sqf:
["myX", "ace_overpressure_fnc_x"] call CBA_fnc_compileFunction;
call compile preprocessFileLineNumbers "z\ace\addons\overpressure\XEH_PReInit.sqf";

That is not what disabling the compile cache is for. It's for debugging.

Close?

I believe PabstMirror's solution will work for what I am attempting.
