| | | | | | | | Partially revert commit 5f2df88b63e50d23914e97ec778861a52abdeaad: add "#undef Yield" to .c files after including Python-ast.h. Fix the warning: winbase.h(102): warning C4005: 'Yield': macro redefinition
* 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).

| | | | | | | | | 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 Stinner2018-11-222-5/+7
| | | Don't pass void* to Python macros: use _PyObject_CAST().
* bpo-35059: Cleanup usage of Python macros (GH-10648)Victor Stinner2018-11-223-89/+112
| | | | | | | | | | | | | 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: Convert _PyObject_GC_TRACK() to inline function (GH-10643)Victor Stinner2018-11-221-6/+7
| | | | | | | | | | | | | * 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-35081: Add Include/internal/pycore_object.h (GH-10640)Victor Stinner2018-11-218-1/+9
| | | | Move _PyObject_GC_TRACK() and _PyObject_GC_UNTRACK() from Include/objimpl.h to Include/internal/pycore_object.h.
* 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 Storchaka2018-11-201-48/+51
| | | | | | | | 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-28604: Fix localeconv() for different LC_MONETARY (GH-10606)Victor Stinner2018-11-202-17/+94
| | | | | | | | | | | | | | | | | | | | | 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.
* Fix a possible reference leak in _socket.getaddrinfo(). (GH-10543)Zackery Spytz2018-11-141-2/+4
| | | "single" needs to be decrefed if PyList_Append() fails.
* bpo-35233: InitConfigTests tests more config vars (GH-10541)Victor Stinner2018-11-141-35/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | test_embed.InitConfigTests tests more configuration variables. Changes: * InitConfigTests tests more core configuration variables: * base_exec_prefix * base_prefix * exec_prefix * home * legacy_windows_fs_encoding * legacy_windows_stdio * module_search_path_env * prefix * "_testembed init_from_config" tests more variables: * argv * warnoptions * xoptions * InitConfigTests: add check_global_config(), check_core_config() and check_main_config() subfunctions to cleanup the code. Move also constants at the class level (ex: COPY_MAIN_CONFIG). * Fix _PyCoreConfig_AsDict(): don't set stdio_encoding twice * Use more macros in _PyCoreConfig_AsDict() and _PyMainInterpreterConfig_AsDict() to reduce code duplication. * Other minor cleanups.
* bpo-35233: Rewrite test_embed.InitConfigTests (GH-10524)Victor Stinner2018-11-131-4/+12
| | | | | | | | | | | | * Fix _PyCoreConfig_SetGlobalConfig(): set also Py_FrozenFlag * Fix _PyCoreConfig_AsDict(): export also xoptions * Add _Py_GetGlobalVariablesAsDict() and _testcapi.get_global_config() * test.pythoninfo: dump also global configuration variables * _testembed now serializes global, core and main configurations using JSON to reuse _Py_GetGlobalVariablesAsDict(), _PyCoreConfig_AsDict() and _PyMainInterpreterConfig_AsDict(), rather than duplicating code. * test_embed.InitConfigTests now test much more configuration variables
* bpo-35233: Fix _PyMainInterpreterConfig_Copy() (GH-10519)Victor Stinner2018-11-132-14/+81
| | | | | | | | * Fix _PyMainInterpreterConfig_Copy(): copy 'install_signal_handlers' attribute * Add _PyMainInterpreterConfig_AsDict() * Add unit tests on the main interpreter configuration to test_embed.InitConfigTests * test.pythoninfo: log also main_config
* bpo-29564:_PyMem_DumpTraceback() suggests enabling tracemalloc (GH-10510)Victor Stinner2018-11-131-0/+6
| | | | | If tracemalloc is not tracing Python memory allocations, _PyMem_DumpTraceback() now suggests to enable tracemalloc to get the traceback where the memory block has been allocated.
* bpo-34784: Fix PyStructSequence_NewType with heap-allocated StructSequence ↵Eddie Elizondo2018-11-132-41/+80
| | | | (GH-9665)
* bpo-35081: Make some _PyGC macros internal (GH-10507)Victor Stinner2018-11-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | * Move "GC" macros together: * PyObject_IS_GC() * _Py_AS_GC() * _PyObject_GC_IS_TRACKED() * _PyObject_GC_MAY_BE_TRACKED() * Mark other GC macros as internal (#ifdef Py_BUILD_CORE): * _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) * _PyObject_GC_TRACK(o), _PyObject_GC_UNTRACK(o) * _PyGC_PREV_MASK_FINALIZED * _PyGC_PREV_MASK_COLLECTING * _PyGC_PREV_SHIFT * _PyGC_PREV_MASK * Replace _PyGC_generation0 with _PyRuntime.gc.generation0 * _queuemodule.c: replace _PyObject_GC_UNTRACK() with with PyObject_GC_UnTrack() * Document that _PyObject_GC_TRACK() _PyObject_GC_UNTRACK() macros have been removed from the public C API.
* bpo-35081: Remove Py_BUILD_CORE from datetime.h (GH-10416)Paul Ganssle2018-11-131-8/+21
| | | | | | | | | | | | | | 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-35214: Add _Py_ prefix to MEMORY_SANITIZER def. (GH-10503)Gregory P. Smith2018-11-132-4/+4
| | | | Rename our new MEMORY_SANITIZER define to _Py_MEMORY_SANITIZER. Project based C Preprocessor namespacing at its finest. :P
* bpo-35214: Initial clang MemorySanitizer support (GH-10479)Gregory P. Smith2018-11-123-1/+19
| | | | | | | | | | 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.
* bpo-35081: Rename internal headers (GH-10275)Victor Stinner2018-11-128-12/+12
| | | | | | | | | | | | | | Rename Include/internal/ headers: * pycore_hash.h -> pycore_pyhash.h * pycore_lifecycle.h -> pycore_pylifecycle.h * pycore_mem.h -> pycore_pymem.h * pycore_state.h -> pycore_pystate.h Add missing headers to Makefile.pre.in and PCbuild: * pycore_condvar.h. * pycore_hamt.h * pycore_pyhash.h
* bpo-35177: Add dependencies between header files (GH-10361)Victor Stinner2018-11-111-3/+2
| | | | | | | | | | | | | | * ast.h now includes Python-ast.h and node.h * parsetok.h now includes node.h and grammar.h * symtable.h now includes Python-ast.h * Modify asdl_c.py to enhance Python-ast.h: * Add #ifndef/#define Py_PYTHON_AST_H to be able to include the header twice * Add "extern { ... }" for C++ * Undefine "Yield" macro conflicting with winbase.h * Remove "#undef Yield" from C files, it's now done in Python-ast.h * Remove now useless includes in C files
* bpo-35199: Add an internal _PyTuple_ITEMS() macro (GH-10434)Victor Stinner2018-11-092-4/+4
| | | | | | | * _PyTuple_ITEMS() gives access to the tuple->ob_item field and cast the first argument to PyTupleObject*. This internal macro is only usable if Py_BUILD_CORE is defined. * Replace &PyTuple_GET_ITEM(ob, 0) with _PyTuple_ITEMS(ob). * Replace PyTuple_GET_ITEM(op, 1) with &_PyTuple_ITEMS(ob)[1].
* bpo-35081: Internal headers require Py_BUILD_CORE (GH-10363)Victor Stinner2018-11-091-0/+1
| | | | | | | | | * All internal header files now require Py_BUILD_CORE or Py_BUILD_CORE_BUILTIN to be defined. * _json.c is now compiled with Py_BUILD_CORE_BUILTIN to access pycore_accu.h header. * Add an example to Modules/Setup to show how to build _json as a built-in module; it requires non trivial compiler options.
* Fixing wording in comment. (GH-10425)Raymond Hettinger2018-11-091-1/+1
| | | | Since the n==1 case just returns *max*, it cannot be larger than the magnitude of the vector entry.
* bpo-35194: Fix a wrong constant in cp932 codec (GH-10420)Alexey Izbyshev2018-11-091-1/+1
| | | | | | | | | | | This typo doesn't affect the result because wrong bits are discarded on implicit conversion to unsigned char, but it trips UBSan with -fsanitize=implicit-integer-truncation. https://bugs.python.org/issue35194
* bpo-35081: Add pycore_fileutils.h (GH-10371)Victor Stinner2018-11-061-0/+1
| | | | Move Py_BUILD_CORE code from Include/fileutils.h to a new Include/internal/pycore_fileutils.h file.
* bpo-35081: Add _PyCoreConfig_AsDict() (GH-10362)Victor Stinner2018-11-061-147/+5
| | | | | | | | | | | | _testcapimodule.c must not include pycore_pathconfig.h, since it's an internal header files. Changes: * Add _PyCoreConfig_AsDict() function to coreconfig.c. * Remove pycore_pathconfig.h include from _testcapimodule.h. * pycore_pathconfig.h now requires Py_BUILD_CORE to be defined. * _testcapimodule.c compilation now fails if it's built with Py_BUILD_CORE defined.
* Fix possible crashes in pwdmodule.c. (GH-10331)Zackery Spytz2018-11-051-0/+2
| | | "p" was not initialized if the first PyMem_RawRealloc() call failed.
* bpo-35133: Fix mistakes when concatenate string literals on different lines. ↵Serhiy Storchaka2018-11-053-4/+4
| | | | | | | | | | (GH-10284) Two kind of mistakes: 1. Missed space. After concatenating there is no space between words. 2. Missed comma. Causes unintentional concatenating in a list of strings.
* closes bpo-32285: Add unicodedata.is_normalized. (GH-4806)Max Bélanger2018-11-042-21/+134
|
* bpo-35161: Fix stack-use-after-scope in grp.getgr{nam,gid} and ↵Alexey Izbyshev2018-11-042-4/+8
| | | | | | pwd.getpw{nam,uid}. (GH-10319) Reported by ASAN.
* bpo-29341: Clarify that path-like objects are accepted in some os methods ↵BNMetrics2018-11-022-31/+31
| | | | | (GH-10101) Some methods in the os module can accept path-like objects. This is documented in the general documentation but not in the function docstrings. To keep both in sync, the docstrings need to be updated to reflect that path-like objects are also accepted.
* bpo-33578: Fix getstate/setstate for CJK decoder (GH-10290)Christopher Thorne2018-11-021-5/+22
| | | | Previous version was casting to Py_ssize_t incorrectly and exhibited unexpected behavior on big-endian systems.
* closes bpo-35139: The `pyexpat` module's macros in `Modules/Setup` now match ↵Max Bélanger2018-11-021-1/+1
| | | | | `setup.py` (GH-10289) This could cause compile errors on macOS or other platforms.
* bpo-33578: Add getstate/setstate for CJK codec (GH-6984)Christopher Thorne2018-11-014-22/+273
| | | | | | | | This implements getstate and setstate for the cjkcodecs multibyte incremental encoders/decoders, primarily to fix issues with seek/tell. The encoder getstate/setstate is slightly tricky as the "state" is pending bytes + MultibyteCodec_State but only an integer can be returned. The approach I've taken is to encode this data into a long, similar to how .tell() encodes a "cookie_type" as a long. https://bugs.python.org/issue33578
* bpo-35081: And pycore_lifecycle.h and pycore_pathconfig.h (GH-10273)Victor Stinner2018-11-013-5/+9
| | | | | | | | | | * And pycore_lifecycle.h and pycore_pathconfig.h headers to Include/internal/ * Move Py_BUILD_CORE specific code from coreconfig.h and pylifecycle.h to pycore_pathconfig.h and pycore_lifecycle.h * Move _Py_wstrlist_XXX() definitions and _PyPathConfig code from pycore_state.h to pycore_pathconfig.h * Move "Init" and "Fini" function definitions from pylifecycle.c to pycore_lifecycle.h.
* bpo-35081: Move accu.h to Include/internal/pycore_accu.h (GH-10271)Victor Stinner2018-11-012-2/+2
| | | | | | | The accu.h header is no longer part of the Python C API: it has been moved to the "internal" headers which are restricted to Python itself. Replace #include "accu.h" with #include "pycore_accu.h".
* bpo-35081: Add _PyThreadState_GET() internal macro (GH-10266)Victor Stinner2018-11-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | If Py_BUILD_CORE is defined, the PyThreadState_GET() macro access _PyRuntime which comes from the internal pycore_state.h header. Public headers must not require internal headers. Move PyThreadState_GET() and _PyInterpreterState_GET_UNSAFE() from Include/pystate.h to Include/internal/pycore_state.h, and rename PyThreadState_GET() to _PyThreadState_GET() there. The PyThreadState_GET() macro of pystate.h is now redefined when pycore_state.h is included, to use the fast _PyThreadState_GET(). Changes: * Add _PyThreadState_GET() macro * Replace "PyThreadState_GET()->interp" with _PyInterpreterState_GET_UNSAFE() * Replace PyThreadState_GET() with _PyThreadState_GET() in internal C files (compiled with Py_BUILD_CORE defined), but keep PyThreadState_GET() in the public header files. * _testcapimodule.c: replace PyThreadState_GET() with PyThreadState_Get(); the module is not compiled with Py_BUILD_CORE defined. * pycore_state.h now requires Py_BUILD_CORE to be defined.
* bpo-35081: Add pycore_ prefix to internal header files (GH-10263)Victor Stinner2018-10-3111-21/+21
| | | | | | | | | | | | | | | | | | | | * Rename Include/internal/ header files: * pyatomic.h -> pycore_atomic.h * ceval.h -> pycore_ceval.h * condvar.h -> pycore_condvar.h * context.h -> pycore_context.h * pygetopt.h -> pycore_getopt.h * gil.h -> pycore_gil.h * hamt.h -> pycore_hamt.h * hash.h -> pycore_hash.h * mem.h -> pycore_mem.h * pystate.h -> pycore_state.h * warnings.h -> pycore_warnings.h * PCbuild project, Makefile.pre.in, Modules/Setup: add the Include/internal/ directory to the search paths of header files. * Update includes. For example, replace #include "internal/mem.h" with #include "pycore_mem.h".
