* bpo-28604: Fix localeconv() for different LC_MONETARY (GH-10606)Victor Stinner2018-11-208-60/+145
| | | | | | | | | | | | | | | | | | | | | locale.localeconv() now sets temporarily the LC_CTYPE locale to the LC_MONETARY locale if the two locales are different and monetary strings are non-ASCII. This temporary change affects other threads. Changes: * locale.localeconv() can now set LC_CTYPE to LC_MONETARY to decode monetary fields. * Add LocaleInfo.grouping_buffer: copy localeconv() grouping string since it can be replaced anytime if a different thread calls localeconv(). * _Py_GetLocaleconvNumeric() now requires a "struct lconv *" structure, so locale.localeconv() now longer calls localeconv() twice. Moreover, the function now requires all arguments to be non-NULL. * Rename STATIC_LOCALE_INFO_INIT to LocaleInfo_STATIC_INIT. * Move _Py_GetLocaleconvNumeric() definition from fileutils.h to pycore_fileutils.h. pycore_fileutils.h now includes locale.h. * The _locale module is now built with Py_BUILD_CORE defined.

* bpo-35081: Remove Py_BUILD_CORE from datetime.h (GH-10416)Paul Ganssle2018-11-132-29/+28
| | | | | | | | | | | | | | Datetime macros like PyDate_Check() have two implementations, one using the C API capsule and one using direct access to the datetime type symbols defined in _datetimemodule.c. Since the direct access versions of the macros are only used in _datetimemodule.c, they have been moved out of "datetime.h" and into _datetimemodule.c. The _PY_DATETIME_IMPL macro is currently necessary in order to avoid both duplicate definitions of these macros in _datetimemodule.c and unnecessary declarations of C API capsule-related macros and varibles in datetime.h.

* bpo-29564: warnings suggests to enable tracemalloc (GH-10486)Victor Stinner2018-11-133-11/+40
| | | | | The warnings module now suggests to enable tracemalloc if the source is specified, tracemalloc module is available, but tracemalloc is not tracing memory allocations.
* bpo-35214: Initial clang MemorySanitizer support (GH-10479)Gregory P. Smith2018-11-129-4/+115
| | | | | | | | | | Adds configure flags for msan and ubsan builds to make it easier to enable. 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.
