http://replays.springrts.com/replay/b75791559dee6fbf008ac254f5de8711 I managed to reproduce the memory allocation with just the projectile lights widget, all other lua turned off. It's possible to also reproduce it with just a few instances of the fleagoth, merely 5 or so will do. Once the memory exceeds some amount the GC never catches up. |
|
|
Here is the same thing reproduced with 8 fleagoths and 2 core bases (they can't die, they have to be captured, it's a NOTA mode in xta) http://replays.springrts.com/replay/fa5991559dee6fbf6df924fb0e889dd9/ With projectile light the memory allocation goes up to 750 Mb, with luaui reload it is freed. Without that widget the memory allocation is stable at 12 Mb. |

doesn't that just mean your widget has issues? |
|
|
Yes, the widget has issues, maybe the discussion can continue here: https://springrts.com/phpbb/viewtopic.php?f=23&t=32631&p=562147&hilit=projectile+lights#p562147 But this is easy to say only because I knew the issue was likely this widget, there was a lot of troubleshooting before we could isolate it. Does the engine monitor luaui memory allocation on widget level? Does the widgethandler have access to memory allocation? Can a warning message be written to infolog when luaui memory allocation exceeds a certain level? When engine shuts off luaui when it reaches more memory than 750 mb, is it possible to pass this information to luaui with a callin so gamedevs can take the proper action? |

I'm not going to implement any of the things you mentioned myself. |
|
|
i don't see this happen in a reasonable timeframe. contributions welcome! but i don't think that it is doable in a way that doesn't impact the performance badly. currently the engine can't distingish between lua widgets or gadgets, it only knows about the lua states/instances. |
