[New-bugs-announce] [issue21163] asyncio Task Possibly Incorrectly Garbage Collected

Richard Kiss report at bugs.python.org
Sat Apr 5 23:10:31 CEST 2014


New submission from Richard Kiss:

Some tasks created via asyncio are vanishing because there is no reference to their resultant futures.

This behaviour does not occur in Python 3.3.3 with asyncio-0.4.1.

Also, doing a gc.collect() immediately after creating the tasks seems to fix the problem.
