I've added some debugging code but don't have time for further investigation |

Thanks! * Added a new ThrowawayDrawBagCanMemLeak data type, and this internally uses our existing ThrowawayListCanMemLeak type (which is mostly used in mapgen until now). ** These are used for very short periods of time, and are meant to be thrown to the garbage collector. I had wanted to avoid this sort of thing, but we've been having persistent intermittent issues with cross-threading issues on certain worker methods (like for wave spawn), and the RapidAntiLeakPoolable approach that I had developed is just not robust enough. I also worry about that contention on that leading to slowdown in larger games. ** I am going to build out some more of these kinds of throwaway collections and probably will phase out a lot of the RapidAntiLeakPoolable thing since it seems to only be causing problems. ** There is also a new interface called IDrawBag<T>, which can be used to manipulate either kind of draw bag without knowing or caring which kind it is. *** I actually am not yet using that on any methods, because on the methods where it would be relevant, I actually want to signal that only a throwaway draw bag should be used, because the sorts of manipulations that are being done in those methods are not for permanent data. ** As an aside, this should not be taken as a signal by modders/developers to just use the throwaway collections willy-nilly. There are many better code patterns, such as not using a collection at all and instead using an iterator/dofor, which have the benefit of both performance and better memory usage, while still having the same amount of readability. *** This is essentially something that should be used in place of places where we were using RapidAntiLeakPoolable stuff before, because that had its own performance implications and occasional cross-threading issues. If you can refactor slightly to avoid the need for any of this, and just use an iterator, then so much the better. |
