Error with the TOTAL_MEMORY parameter

[stoomm]

Hello,

I made a rapid benchmark test file for testing performance with constraints.
When I launch the test, I've this error :

uncaught exception: Assertion: Cannot enlarge memory arrays. Either (1) compile with -s TOTAL_MEMORY=X with X higher than the current value ( 20971520), (2) compile with ALLOW_MEMORY_GROWTH which adjusts the size at runtime but prevents some optimizations, or (3) set Module.TOTAL_MEMORY before the program runs.

I think there an error because :

• ammo was compiled with TOTAL_MEMORY=52428800 (50Mb), not 20Mb ( 20971520)
• setting TOTAL_MEMORY in the source with Ammo.TOTAL_MEMORY=xxxxxxx doesn't work (always 20 Mb instead 50Mb)

File for test : http://www.stoomm.com/benchconstraint.js (lauch with test.py)

Thanks a lot for your help.

The message was misleading about 20MB/50MB, I fixed that now.

The problem with changing Ammo.TOTAL_MEMORY is that it must be done during load of ammo.js - it is fixed at startup, and cannot be changed later (unless you build with ALLOW_MEMORY_GROWTH, which slows things down). What you can do is either (1) change in ammo.js where it says Module.TOTAL_MEMORY||52428800, altering that number will change it, or (2) add this JS code before you load ammo.js: var Module = { TOTAL_MEMORY: ... };, during startup ammo.js will look at the Module object.

I saw the test runner used to do that and set it to 20MB, which is not needed now that the default is 50MB. I removed it from the test runner now.
