* bpo-35233: InitConfigTests tests more config vars (GH-10541)Victor Stinner2018-11-142-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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-35230: dict: Remove some macros (GH-10513)INADA Naoki2018-11-141-2/+0
| | | | Remove _Py_REF_DEBUG_COMMA, DK_DEBUG_INCREF, and DK_DEBUG_DECREF. Convert DK_INCREF and DK_DECREF to static inline functions.
* bpo-35233: Rewrite test_embed.InitConfigTests (GH-10524)Victor Stinner2018-11-131-0/+1
| | | | | | | | | | | | * 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 Stinner2018-11-131-0/+2
| | | | | | | | * 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-35081: Make some _PyGC macros internal (GH-10507)Victor Stinner2018-11-132-29/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | * 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 Ganssle2018-11-131-21/+7
| | | | | | | | | | | | | | 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. Smith2018-11-131-2/+2
| | | | 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. Smith2018-11-121-0/+9
| | | | | | | | | | 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 Stinner2018-11-125-2/+2
| | | | | | | | | | | | | | 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 Stinner2018-11-114-3/+23
| | | | | | | | | | | | | | * 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 Stinner2018-11-091-0/+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 Stinner2018-11-0914-12/+44
| | | | | | | | | * 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.
* bpo-35081: Add pycore_fileutils.h (GH-10371)Victor Stinner2018-11-062-46/+49
| | | | 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 Stinner2018-11-062-2/+7
| | | | | | | | | | | | _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.
* bpo-33462: Add __reversed__ to dict and dict views (GH-6827)Rémi Lapeyre2018-11-061-0/+3
|
* bpo-35147: Fix _Py_NO_RETURN for GCC (GH-10300)Alexey Izbyshev2018-11-021-3/+3
| | | | | | | | | Use `__GNUC__` instead of non-existing `__GNUC_MAJOR__`. https://bugs.python.org/issue35147
* bpo-35081: And pycore_lifecycle.h and pycore_pathconfig.h (GH-10273)Victor Stinner2018-11-015-89/+120
| | | | | | | | | | * 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 Stinner2018-11-011-9/+7
| | | | | | | 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 Stinner2018-11-012-25/+65
| | | | | | | | | | | | | | | | | | | | | | | | | 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 Stinner2018-10-3112-9/+9
| | | | | | | | | | | | | | | | | | | | * 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".
* bpo-35081: Move Py_BUILD_CORE code to internal/mem.h (GH-10249)Victor Stinner2018-10-312-10/+12
| | | | | * Add #include "internal/mem.h" to C files using _PyMem_SetDefaultAllocator(). * Include/internal/mem.h now requires Py_BUILD_CORE to be defined.
* bpo-35081: Move Include/pyatomic.c to Include/internal/ (GH-10239)Victor Stinner2018-10-305-9/+15
| | | Add pyatomic.h to the VS project (it wasn't referenced).
* bpo-35081: Cleanup pystate.c and pystate.h (GH-10240)Victor Stinner2018-10-301-4/+3
| | | | | | | | | | | | * Remove _PyThreadState_Current * Replace GET_TSTATE() with PyThreadState_GET() * Replace GET_INTERP_STATE() with _PyInterpreterState_GET_UNSAFE() * Replace direct access to _PyThreadState_Current with PyThreadState_GET() * Replace _PyThreadState_Current with _PyRuntime.gilstate.tstate_current * Rename SET_TSTATE() to _PyThreadState_SET(), name more consistent with _PyThreadState_GET() * Update outdated comments
* bpo-35059: Convert _Py_Dealloc() to static inline function (GH-10223)Victor Stinner2018-10-301-6/+15
| | | | | Convert _Py_Dealloc() macro into a static inline function. Moreover, it is now also defined as a static inline function if Py_TRACE_REFS is defined.
* bpo-32030: Make _PySys_AddXOptionWithError() private (GH-10236)Victor Stinner2018-10-301-5/+0
| | | | | | | | Make _PySys_AddXOptionWithError() and _PySys_AddWarnOptionWithError() functions private again. They are no longer needed to initialize Python: _PySys_EndInit() is now responsible to add these options instead. Moreover, PySys_AddWarnOptionUnicode() now clears the exception on failure if possible.
* bpo-34523: Fix config_init_fs_encoding() for ASCII (GH-10232)Victor Stinner2018-10-301-0/+2
| | | | | | | * bpo-34523, bpo-34403: Fix config_init_fs_encoding(): it now uses ASCII if _Py_GetForceASCII() is true. * Fix a regression of commit b2457efc78b74a1d6d1b77d11a939e886b8a4e2c. * Fix also a memory leak: get_locale_encoding() already allocates memory, no need to duplicate the string.
* bpo-33237: Improve AttributeError message for partially initialized module. ↵Serhiy Storchaka2018-10-301-0/+1
| | | | (GH-6398)
* bpo-35059: Convert Py_XINCREF() to static inline function (GH-10224)Victor Stinner2018-10-291-13/+17
| | | | Convert Py_XINCREF() and Py_XDECREF() macros into static inline functions.
* bpo-35059: Remove Py_STATIC_INLINE() macro (GH-10216)Victor Stinner2018-10-293-42/+25
| | | | "static inline" should be used directly. Forcing the compiler to inline is not recommended.
* bpo-35059: Convert Py_INCREF() to static inline function (GH-10079)Victor Stinner2018-10-291-29/+42
| | | | | * Convert Py_INCREF() and Py_DECREF() macros into static inline functions. * Remove _Py_CHECK_REFCNT() macro: code moved into Py_DECREF().
* bpo-35064 prefix smelly symbols that appear with COUNT_ALLOCS with _Py_ ↵Pablo Galindo2018-10-281-4/+4
| | | | | | | (GH-10152) Configuring python with ./configure --with-pydebug CFLAGS="-D COUNT_ALLOCS -O0" makes "make smelly" fail as some symbols were being exported without the "Py_" or "_Py" prefixes.
* bpo-35059: Convert PyObject_INIT() to function (GH-10077)Victor Stinner2018-10-261-6/+23
| | | | | * Convert PyObject_INIT() and PyObject_INIT_VAR() macros to static inline functions. * Fix usage of these functions: cast to PyObject* or PyVarObject*.
* bpo-35053: Define _PyTraceMalloc_NewReference in object.h (GH-10107)Victor Stinner2018-10-252-4/+4
| | | | | | _PyTraceMalloc_NewReference() is now called by _Py_NewReference(), so move its definition to object.h. Moreover, define it even if Py_LIMITED_API is defined, since _Py_NewReference() is also exposed even if Py_LIMITED_API is defined.
* bpo-9263: Dump Python object on GC assertion failure (GH-10062)Victor Stinner2018-10-252-1/+48
| | | | | | | | | | | | | | | | | | | | | | | Changes: * Add _PyObject_AssertFailed() function. * Add _PyObject_ASSERT() and _PyObject_ASSERT_WITH_MSG() macros. * gc_decref(): replace assert() with _PyObject_ASSERT_WITH_MSG() to dump the faulty object if the assertion fails. _PyObject_AssertFailed() calls: * _PyMem_DumpTraceback(): try to log the traceback where the object memory has been allocated if tracemalloc is enabled. * _PyObject_Dump(): log repr(obj). * Py_FatalError(): log the current Python traceback. _PyObject_AssertFailed() uses _PyObject_IsFreed() heuristic to check if the object memory has been freed by a debug hook on Python memory allocators. Initial patch written by David Malcolm. Co-Authored-By: David Malcolm <dmalcolm@redhat.com>
* bpo-35059: Add Py_STATIC_INLINE() macro (GH-10093)Victor Stinner2018-10-253-36/+53
| | | | | | | | | * Add Py_STATIC_INLINE() macro to declare a "static inline" function. If the compiler supports it, try to always inline the function even if no optimization level was specified. * Modify pydtrace.h to use Py_STATIC_INLINE() when WITH_DTRACE is not defined. * Add an unit test on Py_DECREF() to make sure that _Py_NegativeRefcount() reports the correct filename.
* bpo-35053: Add Include/tracemalloc.h (GH-10091)Victor Stinner2018-10-254-37/+49
| | | | | | | * Modify object.h to ensure that pymem.h is included, to get _Py_tracemalloc_config variable. * Move _PyTraceMalloc_XXX() functions to tracemalloc.h, they need PyObject type. Break circular dependency between pymem.h and object.h.
* bpo-35053: Enhance tracemalloc to trace free lists (GH-10063)Victor Stinner2018-10-252-0/+41
| | | | | | | | | | | | tracemalloc now tries to update the traceback when an object is reused from a "free list" (optimization for faster object creation, used by the builtin list type for example). Changes: * Add _PyTraceMalloc_NewReference() function which tries to update the Python traceback of a Python object. * _Py_NewReference() now calls _PyTraceMalloc_NewReference(). * Add an unit test.
* bpo-9263: _PyObject_Dump() detects freed memory (GH-10061)Victor Stinner2018-10-232-1/+4
| | | | | | | | | _PyObject_Dump() now uses an heuristic to check if the object memory has been freed: log "<freed object>" in that case. The heuristic rely on the debug hooks on Python memory allocators which fills the memory with DEADBYTE (0xDB) when memory is deallocated. Use PYTHONMALLOC=debug to always enable these debug hooks.
* Update opcode.h header comment to mention the source data file (GH-9935)Shivank982018-10-181-1/+1
| | | This is intended to help code explorers find out more about what's defined there.
* bpo-24658: Fix read/write greater than 2 GiB on macOS (GH-1705)Stéphane Wirtel2018-10-171-0/+13
| | | On macOS, fix reading from and writing into a file with a size larger than 2 GiB.
