* bpo-36820: Break unnecessary cycle in socket.py, codeop.py and dyld.py ↵Mario Corchero2019-12-061-0/+2
| | | | | | | | | | | | (GH-13135) Break cycle generated when saving an exception in socket.py, codeop.py and dyld.py as they keep alive not only the exception but user objects through the ``__traceback__`` attribute. https://bugs.python.org/issue36820 Automerge-Triggered-By: @pablogsal
* Remove binding of captured exceptions when not used to reduce the chances of ↵Pablo Galindo2019-11-191-1/+1
| | | | | | | creating cycles (GH-17246) Capturing exceptions into names can lead to reference cycles though the __traceback__ attribute of the exceptions in some obscure cases that have been reported previously and fixed individually. As these variables are not used anyway, we can remove the binding to reduce the chances of creating reference cycles. See for example GH-13135

* bpo-37140: Fix StructUnionType_paramfunc() (GH-15612)Victor Stinner2019-08-301-6/+45
| | | | | | | | | | | | Fix a ctypes regression of Python 3.8. When a ctypes.Structure is passed by copy to a function, ctypes internals created a temporary object which had the side effect of calling the structure finalizer (__del__) twice. The Python semantics requires a finalizer to be called exactly once. Fix ctypes internals to no longer call the finalizer twice. Create a new internal StructParam_Type which is only used by _ctypes_callproc() to call PyMem_Free(ptr) on Py_DECREF(argument). StructUnionType_paramfunc() creates such object.

* bpo-36946: Fix possible signed integer overflow when handling slices. (GH-13375)Zackery Spytz2019-05-171-0/+11
| | | | | | | The final addition (cur += step) may overflow, so use size_t for "cur". "cur" is always positive (even for negative steps), so it is safe to use size_t here. Co-Authored-By: Martin Panter <vadmium+py@gmail.com>

* bpo-27643 - skip test_ctypes test case with XLC compiler. (GH-5164)Michael Felt2018-12-261-0/+4
| | | | | | | | | This test case needs "signed short" bitfields, but the IBM XLC compiler (on AIX) does not support this. Skip the code and test when AIX and XLC are used. Use __xlc__ as identifier to detect the XLC compiler.
* bpo-35523: Remove ctypes callback workaround (GH-11211)Victor Stinner2018-12-181-5/+0

* bpo-10746: Fix ctypes PEP 3118 type codes for c_long, c_bool, c_int (#31)Pauli Virtanen2017-08-281-28/+55
| | | | | | | | | | | | | | | Ctypes currently produces wrong pep3118 type codes for several types. E.g. memoryview(ctypes.c_long()).format gives "<l" on 64-bit platforms, but it should be "<q" instead for sizeof(c_long) == 8 The problem is that the '<>' endian specification in the struct syntax also turns on the "standard size" mode, which makes type characters have a platform-independent meaning, which does not match with the codes used internally in ctypes. The struct module format syntax also does not allow specifying native-size non-native-endian items. This commit adds a converter function that maps the internal ctypes codes to appropriate struct module standard-size codes in the pep3118 format strings. The tests are modified to check for this.
* [security] bpo-13617: Reject embedded null characters in wchar* strings. (#2302)Serhiy Storchaka2017-06-281-0/+2
| | | | | | | Based on patch by Victor Stinner. Add private C API function _PyUnicode_AsUnicode() which is similar to PyUnicode_AsUnicode(), but checks for null characters.
* bpo-30708: Check for null characters in PyUnicode_AsWideCharString(). (#2285)Serhiy Storchaka2017-06-271-2/+2
| | | | | Raise a ValueError if the second argument is NULL and the wchar_t\* string contains null characters.

| | | Also fixed a few more line endings that were missed in GH-840, which were causing failure.
