[issue22068] test_gc fails after test_idle
Terry J. Reedy added the comment: ConfigDialog is a good guess as I added a minimal test this month. I will try to revise to not create loops in the first place. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue22068 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue22068] test_gc fails after test_idle
Serhiy Storchaka added the comment: Here is a patch against 2.7 which get rid of reference loops in Tk variables and Font. This will fix not only ConfigDialog, but any similar user code. In 3.4+ such reference loops are successfully resolved, but I think we should foreport this path to 3.4+ because it also fixes other minor bug: callbacks registered to trace variable now live while the variable lives, not while widget lives. -- assignee: - serhiy.storchaka components: +Tkinter stage: - patch review Added file: http://bugs.python.org/file36105/tkinter_refloops-2.7.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue22068 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

STINNER Victor added the comment: It looks like test_idle leaks uncollectable objects. I modified regrtest to use tracemalloc, I attach the output: tracemalloc.txt.

Serhiy Storchaka added the comment: Indeed, there are a lot of small reference loops in ConfigDialog. Tk variables save reference to the dialog and the dialog saves references to variables. Either variables should be created with different argument (i.e. self.parent), or they should be deleted when ConfigDialog is destroyed. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue22068 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
