New submission from Kevin Watters <[EMAIL PROTECTED]>: in Lib/ctypes/__init__.py the wstring_at and string_at functions are declared with CFUNCTYPE.
This means that in Modules/_ctypes/callproc.c when the functions are invoked, Py_UNBLOCK_THREADS and Py_BLOCK_THREADS surround the call. But string_at and wstring_at call PyString_FromString and PyUnicode_FromWideChar, respectively. The solution (I think) is to declare the functions with PYFUNCTYPE instead, so that callproc.c doesn't release the GIL when calling them. ---------- assignee: theller components: ctypes messages: 71135 nosy: kevinwatters, theller severity: normal status: open title: ctypes.wstring_at and string_at call Python API without the GIL type: crash versions: Python 2.5, Python 2.6, Python 2.7, Python 3.0, Python 3.1 _______________________________________ Python tracker <[EMAIL PROTECTED]> <http://bugs.python.org/issue3554> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
