(Win32 API) callback to Python, threading hiccups

ll I figure out what's really happening. Could someone save my precious and already sparse sleeping time, by pointing me to what I'm missing here? WinXP SP1 Python 2.4.1 MinGW GCC 3.4.2 TIA, Francois De Serres -- http://mail.python.org/mailman/listinfo/python-list

The GIL, callbacks, and GPFs

Hello, I'm chasing a GPF in the interpreter when running my extension module. It's not very elaborated, but uses a system (threaded) callback, and therefore the GIL. Help would be mucho appreciated. Here's the rough picture: win32_spam.c /* code here is unit-tested OK */ typedef st

Building a function call?

Hiho, Having a string: "dothat" and a tuple: (x, y) 1. What's the best way to build a function call like: dothat(x,y)? Assuming dothat is def'd in the same module, 2. is: eval("dothat(x,y)", None, (('x', 100), ('y', 200))) the right way to have it executed? If dothat is def'd in another module:

**kwargs?

All your **kwargs are belong to us. *args is documented in the Tutorial. I reckon **kwargs represents a dictionary of arguments. But I don't quite get the semantics of **x. Undefined length tuple of undefined length tuples? Are there other practical use cases for ** (common enough please, I wis

Documenting extension modules?

Hiho, I can't seem to find a proper way to document my extension module. Following the C API doc: static PyMethodDef ioMethods[] = { {"o_count", o_count, METH_VARARGS, "Return the count of available MIDI outputs."}, } lacks: a) module level documentation b) function parameters Also,

Exception in callback => GPF?

Hiho, When there's an unhandled exception in my extension-module's-callback-into-Python-function-object, I get a GPF and Python exits. When the exception is being handled within the callback (hence in Python), I get a very significant hiccup (1 to 5 seconds freeze). Question: is there a specif

tuple to string?

hiho, what's the clean way to translate the tuple (0x73, 0x70, 0x61, 0x6D) to the string 'spam'? TIA, Francois -- http://mail.python.org/mailman/listinfo/python-list
