New submission from Graham Dumpleton <[EMAIL PROTECTED]>: Because the readline module uses PyGILState_Ensure() to facilitate triggering callbacks into Python code, this would make the ability to use the hook functions incompatible with use in sub interpreters.
If this is the case, then that readline module cannot be used in sub interpreters should be documented if not already. Better still, attempts to register hooks from sub interpreters should result in an exception. Further, when in use, in sub interpreter, callback hooks should also not be called if defined, because if defined they would be the hooks from the main interpreter since variables holding the hooks are static C variables and shared across all interpreters. This issue derived from reading of code only and not tested in real program. ---------- components: Interpreter Core messages: 75201 nosy: grahamd severity: normal status: open title: Multiple interpreters and readline module hook functions. versions: Python 2.5, Python 3.0 _______________________________________ Python tracker <[EMAIL PROTECTED]> <http://bugs.python.org/issue4202> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
