New submission from patrick vrijlandt <patrick.vrijla...@gmail.com>:
Line 154 in standard library's queue.py, in the definition of Queue.put() is: self.unfinished_tasks += 1 This line should be protected by acquiring the all_tasks_done lock. Theoretically, the increment could occur somewhere during task_done()! Additional note: Personally, I would like the increment to occur *before* instead of *after* _put(). This is because I would like to be able to implement a _put() that does not put everything. This put should be able to undo the increment. As it is, calling task_done() from put might decrease the counter to zero inadvertently. ---------- components: Library (Lib) messages: 135063 nosy: patrick.vrijlandt priority: normal severity: normal status: open title: queue.Queue.put should acquire mutex for unfinished_tasks type: behavior versions: Python 3.2 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue11987> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
