Issue #7022 has been updated by rogerdpack (Roger Pack). hmm...correct me if I'm wrong (I'm trying to maintain the ruby-prof gem here) will the dtrace probes in #2565 help me if I'm running profiling in windows? Actually if a hook were added for "GC DONE" or the like, I could query using the API at that point, which would probably be enough. Feedbacks? ---------------------------------------- Feature #7022: add event hook for garbage collection https://bugs.ruby-lang.org/issues/7022#change-29308 Author: rogerdpack (Roger Pack) Status: Open Priority: Normal Assignee: Category: Target version: It would be useful for profilers to have more insight into garbage collection. Feature request: add event hooks for garbage collect start/stop. For the lazy sweep, start and stop events would also be interesting. Thanks. -- http://bugs.ruby-lang.org/
