adrian-prantl30 days ago👍 1We usually do something like this (copied from another test)
DEFAULT_TIMEOUT = 20 * (10 if ("ASAN_OPTIONS" in os.environ) else 1)
to guard against even slower as an bots.
adrian-prantl24 days agoEven better would be to wait for something the target actually does, like reading from stdin or creating a file.
Add actor call to hopefully initialize swift concurrency threads
New algorithm to ensure actor is sufficiently setup
Add IsValid asserts
New approach did not work, restore previous
