| | | | | | | | | Include <pyconfig.h> ealier in Modules/expat/xmltok.c to define properly _POSIX_C_SOURCE.

* bpo-35050: AF_ALG length check off-by-one error (GH-10058) (GH-11069)Victor Stinner2018-12-101-3/+7
| | | | | | | | | The length check for AF_ALG salg_name and salg_type had a off-by-one error. The code assumed that both values are not necessarily NULL terminated. However the Kernel code for alg_bind() ensures that the last byte of both strings are NULL terminated.

| | | | | | | | | | | | In _localemodule.c and selectmodule.c, remove dead code that would cause double decrefs if run. In addition, replace PyList_SetItem() with PyList_SET_ITEM() in cases where a new list is populated and there is no possibility of an error. In addition, check if the list changed size in the loop in array_array_fromlist().

These also encode the detail that address sanitizer and memory sanitizer should disable pymalloc. Define MEMORY_SANITIZER when appropriate at build time and adds workarounds to existing code to mark things as initialized where the sanitizer is otherwise unable to determine that. This lets our build succeed under the memory sanitizer. not all tests pass without sanitizer failures yet but we're in pretty good shape after this.

We agree that it is better to change both the C and pure Python versions to use repr. * Retain non-sanitized dtstr for error printing This does not create an extra string, it just holds on to a reference to the original input string for purposes of creating the error message. * PEP 7 fixes to from_isoformat * Separate handling of Unicode and other errors In the initial implementation, errors other than encoding errors would both raise an error indicating an invalid format, which would not be true for errors like MemoryError. * Drop needs_decref from _sanitize_isoformat_str Instead _sanitize_isoformat_str returns a new reference, even to the original string.
