Category: Library (Lib) Group: Python 2.4 Status: Open Resolution: None Priority: 5 Private: No Submitted By: BC (hashstat) Assigned to: Nobody/Anonymous (nobody) Summary: bug# 1607041: Condition.wait timeout fails on clock change Initial Comment: This patch if for bug# 1607041. If the system clock is adjusted after Condition.wait is called with a timeout, the timeout does not expire as expected. This appears to be due to the threading.Condition class using the system clock to calculate the timeout expiration without taking system clock changes into account. No matter what timeout is used, setting the system clock ahead reduces or eliminates the wait while setting the system clock back increases the wait. So if the clock is set back one hour in the middle of a 1 microsecond wait (c.wait(1)), wait will return in an hour and 1 microsecond rather than after 1 microsecond. This patch modifies the Condition classes wait method to check for variations in the clock between calls to sleep and ajust for abnormalities. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=305470&aid=1607149&group_id=5470 _______________________________________________ Patches mailing list Patches@python.org http://mail.python.org/mailman/listinfo/patches
