* bpo-24658: os.read() reuses _PY_READ_MAX (GH-10657)Victor Stinner2018-11-221-5/+1
| | | | | os_read_impl() now also truncates the size to _PY_READ_MAX on macOS, to avoid to allocate a larger buffer even if _Py_read() is limited to _PY_READ_MAX bytes (ex: INT_MAX on macOS).
* bpo-18407: ast.c uses Py_ssize_t for asdl_seq_LEN() iterator (GH-10655)Victor Stinner2018-11-222-10/+10
| | | | | | | When iterating using asdl_seq_LEN(), use 'Py_ssize_t' type instead of 'int' for the iterator variable, to avoid downcast on 64-bit platforms. _Py_asdl_int_seq_new() now also ensures that the index is greater than or equal to 0.
* bpo-18407: win32_urandom() uses PY_DWORD_MAX (GH-10656)Victor Stinner2018-11-221-4/+2
| | | | | | CryptGenRandom() maximum size is PY_DWORD_MAX, not INT_MAX. Use DWORD type for the 'chunk' variable Co-Authored-By: Jeremy Kloth <jeremy.kloth@gmail.com>
* bpo-9566: Fix compiler warnings in pyexpat.c (GH-10654)Victor Stinner2018-11-221-2/+4
| | | | | | | | | | Explicit cast a pointer difference (intptr_t) to int to fix two warnings on 64-bit Windows: Modules\pyexpat.c(1181): warning C4244: 'initializing': conversion from '__int64' to 'int', possible loss of data Modules\pyexpat.c(1192): warning C4244: 'initializing': conversion from '__int64' to 'int', possible loss of data
* cjkcodecs: Fix compiler warning (GH-10651)Victor Stinner2018-11-221-2/+2
| | | | | | | | | Fixed the following compiler warning in multibytecodec.c: warning C4244: '=': conversion from 'Py_ssize_t' to 'unsigned char', possible loss of data Cast Py_ssize_t to unsigned char: the maximum value is checked on the previous line.
* bpo-35059: Cast void* to PyObject* (GH-10650)Victor Stinner2018-11-224-11/+17
| | | Don't pass void* to Python macros: use _PyObject_CAST().
* bpo-35059: Cleanup usage of Python macros (GH-10648)Victor Stinner2018-11-224-90/+114
| | | | | | | | | | | | | Don't pass complex expressions but regular variables to Python macros. * _datetimemodule.c: split single large "if" into two "if" in date_new(), time_new() and datetime_new(). * _pickle.c, load_extension(): flatten complex "if" expression into more regular C code. * _ssl.c: addbool() now uses a temporary bool_obj to only evaluate the value once. * weakrefobject.c: replace "Py_INCREF(result = proxy);" with "result = proxy; Py_INCREF(result);"
* bpo-35059: Add _PyObject_CAST() macro (GH-10645)Victor Stinner2018-11-225-23/+29
| | | | Add _PyObject_CAST() and _PyVarObject_CAST() macros to cast argument to PyObject* and PyVarObject* properly.
* bpo-35059: Convert _PyObject_GC_TRACK() to inline function (GH-10643)Victor Stinner2018-11-223-42/+68
| | | | | | | | | | | | | * Add _PyObject_ASSERT_FROM() and _PyObject_ASSERT_FAILED_MSG() macros. * PyObject_GC_Track() now calls _PyObject_ASSERT_FAILED_MSG(), instead of Py_FatalError(), if the object is already tracked, to dump more information on error. * _PyObject_GC_TRACK() no longer checks if the object is already tracked at runtime, use an assertion instead for best performances; PyObject_GC_Track() still checks at runtime. * pycore_object.h now includes pycore_pystate.h. * Convert _PyObject_GC_TRACK() and _PyObject_GC_UNTRACK() macros to inline functions.
* bpo-35059: Enhance _PyObject_AssertFailed() (GH-10642)Victor Stinner2018-11-213-14/+20
| | | | | | Enhance _PyObject_AssertFailed() * Exchange 'expr' and 'msg' parameters * 'expr' and 'func' arguments can now be NULL
* bpo-35081: Add Include/internal/pycore_object.h (GH-10640)Victor Stinner2018-11-2134-50/+93
| | | | Move _PyObject_GC_TRACK() and _PyObject_GC_UNTRACK() from Include/objimpl.h to Include/internal/pycore_object.h.
* bpo-35189: Fix eintr_tester.py (GH-10637)Victor Stinner2018-11-211-22/+18
| | | | | | | | | | | | | Call setitimer() before each test method, instead of once per test case, to ensure that signals are sent in each test method. Previously, only the first method of a testcase class got signals. Changes: * Replace setUpClass() with setUp() and replace tearDownClass() with tearDown(). * tearDown() now ensures that at least one signal has been sent. * Replace support.run_unittest() with unittest.main() which has a nicer CLI and automatically discover test cases.
* bpo-35035: Rename email.utils documentation to email.utils.rst (GH-10023)Zhiming Wang2018-11-213-1/+2
| | | I'll watch for 404 on the old URL and will setup an HTTP redirection if needed.
* bpo-35290: Add debug info to test_c_locale_coercion (GH-10631)Victor Stinner2018-11-211-6/+15
| | | | In verbose mode, test_c_locale_coercion now dumps global variables at startup.
* bpo-35221: Additional hint that the placeholder is to be replaced. (GH-10604)Julien Palard2018-11-211-1/+2

* bpo-35081: Move _PyGC_FINALIZED() back to C API (GH-10626)Victor Stinner2018-11-201-3/+3
| | | | | | | | | | | | | | | | Partially revert commit 1a6be91e6fd65ce9cb88cbbbb193db7e92ec6076, move back PyGC API from the internal API to the C API: * _PyGCHead_NEXT(g), _PyGCHead_SET_NEXT(g, p) * _PyGCHead_PREV(g), _PyGCHead_SET_PREV(g, p) * _PyGCHead_FINALIZED(g), _PyGCHead_SET_FINALIZED(g) * _PyGC_FINALIZED(o), _PyGC_SET_FINALIZED(o) * _PyGC_PREV_MASK_FINALIZED * _PyGC_PREV_MASK_COLLECTING * _PyGC_PREV_SHIFT * _PyGC_PREV_MASK _PyObject_GC_TRACK(o) and _PyObject_GC_UNTRACK(o) remain in the internal API.
* bpo-34532: Fixed exit code for py.exe list versions arg (GH-9039)Brendan Gerrity2018-11-202-4/+6

* bpo-25750: Fix a compiler warning introduced in GH-9084. (GH-10234)Serhiy Storchaka2018-11-201-5/+5

* bpo-35021: Fix assertion failures in _datetimemodule.c. (GH-10039)Serhiy Storchaka2018-11-202-54/+88
| | | | | | | | Fixes assertion failures in _datetimemodule.c introduced in the previous fix (see bpo-31752). Rather of trying to handle an int subclass as exact int, let it to use overridden special methods, but check the result of divmod().
* bpo-35169: Improve error messages for forbidden assignments. (GH-10342)Serhiy Storchaka2018-11-206-96/+140

* 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.

| | | | | | | | | | | * The _PySys_EndInit() function now copies the config->module_search_path list, so config is longer modified when sys.path is updated. * config->warnoptions list and config->xoptions dict are also copied * test_embed: InitConfigTests now also tests main_config['module_search_path'] * Fix _Py_InitializeMainInterpreter(): don't use config->warnoptions but sys.warnoptions to decide if the warnings module should be imported at startup.
