I have since learned the following about accessing tk widgets from non-main threads. 1. It seem to be reliable when tcl/tk is compiled with thread support but not when tcl/tk is not so compiled. (The latter is contrary to a claim in the doc.) 2. The tcl default is 'without' 8.5 and 'with' for 8.6, and PSF installers follow the default. I am guessing that this is likely true for Linux distributions. 3. The 2.7 Windows installer currently includes 8.5.15. The 3.5+ Windows installers include 8.6.z. Hence the different results on my Windows machine. 4. Mac installers now use 8.6.z even, I believe, for 2.7. I have the impression that the system tcl/tk for current Linux distributes is also 8.6.z. Hence, the issue of tkinter thread safety is resolving itself. I reran e10909.py with 2.7.16 with the B config call disabled and it ran until I stopped it at 24 minutes. Printing from a thread is not an issue on my machine. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue10909> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
