So I actually didn't get rid of the memory exhaustion problem, but I *did* get rid of the "Dynamic-wind record doesn't match prompt!" error. I'm not sure exactly how the "fix" fixed it though, I mostly moved the code shape closer to the shape it was previously before the error happened. To reproduce, clone goblins: https://gitlab.com/spritely/goblins.git Now check out the commit 1db58e8, which is the v0.1 release Now follow the instructions on the top of: https://gitlab.com/spritely/goblins/issues/8 (the second code block there has some code you can run yourself to reproduce the bug.) More about the "fix": https://gitlab.com/spritely/goblins/issues/8#note_112548932 Note that I still am hitting problems, but they aren't this problem: - Still have the memory leak. It's very hard for me to figure out why references to the promises, promise resolvers, and listeners are not being cleaned up. - A couple of the fixes I've tried have managed to segfault Racket... one crashed the GC. I guess those might be of interest. I didn't have these problems before I moved to the promise-based architecture I'm now using. There's a lot more allocation of intermediate actors powering things now, and I'm okay with some performance tradeoff if it means a cleaner design, but I should probably sort out the leaks and crashes :) - Chris -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
