2016-05-27 Thread Evan Jones
Evan Jones added the comment: I have a crazy idea, but I'm not 100% sure how to implement it: If Python was able to detect and report this error in a friendly way, it would allow people to easily understand what is happening and to work around it. How can we do it? First idea: I

[issue27126] Mac system sqlite3 not fork safe: Bundle a version?

2016-05-25 Thread Evan Jones
New submission from Evan Jones: The system version of libsqlite3 that is included in Mac OS X is not fork safe. This means that if a process forks, and the child calls into it, it will crash with the stack trace below. I've reproduced this with both Python 2.7.10 and Python 3.5.1 on Mac
