* bpo-34784: Fix PyStructSequence_NewType with heap-allocated StructSequence ↵Eddie Elizondo2018-11-131-0/+27
| | | | (GH-9665)
* bpo-35199: Add an internal _PyTuple_ITEMS() macro (GH-10434)Victor Stinner2018-11-091-1/+1
| | | | | | | * _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: 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.
* bpo-35081: And pycore_lifecycle.h and pycore_pathconfig.h (GH-10273)Victor Stinner2018-11-011-3/+4
| | | | | | | | | | * 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: 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-35059: Add Py_STATIC_INLINE() macro (GH-10093)Victor Stinner2018-10-251-0/+22
| | | | | | | | | * 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-25750: Add test on bad descriptor __get__() (GH-9084)jdemeyer2018-10-191-0/+23

* Revert "bpo-34589: Add -X coerce_c_locale command line option (GH-9378)" ↵Victor Stinner2018-09-191-4/+4
| | | | | | | | | | | | | | | | (GH-9430) * Revert "bpo-34589: Add -X coerce_c_locale command line option (GH-9378)" This reverts commit dbdee0073cf0b88fe541980ace1f650900f455cc. * Revert "bpo-34589: C locale coercion off by default (GH-9073)" This reverts commit 7a0791b6992d420dc52536257f2f093851ed7215. * Revert "bpo-34589: Make _PyCoreConfig.coerce_c_locale private (GH-9371)" This reverts commit 188ebfa475a6f6aa2d0ea14ca8e1fbe7865b6d27.
* bpo-34589: Make _PyCoreConfig.coerce_c_locale private (GH-9371)Victor Stinner2018-09-171-4/+4
| | | | | | | | _PyCoreConfig: * Rename coerce_c_locale to _coerce_c_locale * Rename coerce_c_locale_warn to _coerce_c_locale_warn These fields are now private (name prefixed by "_").
* bpo-34567: pythoninfo gets coreconfig (GH-9043)Victor Stinner2018-09-031-0/+155
| | | | | | * Add _testcapi.get_coreconfig() to get the _PyCoreConfig of the interpreter * test.pythoninfo now gets the core configuration using _testcapi.get_coreconfig()
* bpo-34523: Support surrogatepass in locale codecs (GH-8995)Victor Stinner2018-08-291-0/+94
| | | | | | | | | | | | | | | | | | | | Add support for the "surrogatepass" error handler in PyUnicode_DecodeFSDefault() and PyUnicode_EncodeFSDefault() for the UTF-8 encoding. Changes: * _Py_DecodeUTF8Ex() and _Py_EncodeUTF8Ex() now support the surrogatepass error handler (_Py_ERROR_SURROGATEPASS). * _Py_DecodeLocaleEx() and _Py_EncodeLocaleEx() now use the _Py_error_handler enum instead of "int surrogateescape" to pass the error handler. These functions now return -3 if the error handler is unknown. * Add unit tests on _Py_DecodeLocaleEx() and _Py_EncodeLocaleEx() in test_codecs. * Rename get_error_handler() to _Py_GetErrorHandler() and expose it as a private function. * _freeze_importlib doesn't need config.filesystem_errors="strict" workaround anymore.
* Make GenericAlias_Type and Generic_Type static. (GH-8076)Benjamin Peterson2018-07-041-2/+2

* Replace _PyGC_REFS macros with higher level macros (GH-6852)INADA Naoki2018-05-171-2/+1
| | | | Only gcmodule.c uses _PyGC_REFS* macros now. This makes easy to read GC code.
* bpo-33012: Fix invalid function cast warnings with gcc 8 for METH_NOARGS. ↵Siddhesh Poyarekar2018-04-291-76/+71
| | | | | | | | | (GH-6030) METH_NOARGS functions need only a single argument but they are cast into a PyCFunction, which takes two arguments. This triggers an invalid function cast warning in gcc8 due to the argument mismatch. Fix this by adding a dummy unused argument.

| | | | | | | | | | | | | | | | | | | | * Fix _PyMem_SetupAllocators("debug"): always restore allocators to the defaults, rather than only caling _PyMem_SetupDebugHooks(). * Add _PyMem_SetDefaultAllocator() helper to set the "default" allocator. * Add _PyMem_GetAllocatorsName(): get the name of the allocators * main() now uses debug hooks on memory allocators if Py_DEBUG is defined, rather than calling directly malloc() * Document default memory allocators in C API documentation * _Py_InitializeCore() now fails with a fatal user error if PYTHONMALLOC value is an unknown memory allocator, instead of failing with a fatal internal error. * Add new tests on the PYTHONMALLOC environment variable * Add support.with_pymalloc() * Add the _testcapi.WITH_PYMALLOC constant and expose it as support.with_pymalloc(). * sysconfig.get_config_var('WITH_PYMALLOC') doesn't work on Windows, so replace it with support.with_pymalloc(). * pythoninfo: add _testcapi collector for pymem

* bpo-18835: Cleanup pymalloc (#4200)Victor Stinner2017-10-311-7/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | Cleanup pymalloc: * Rename _PyObject_Alloc() to pymalloc_alloc() * Rename _PyObject_FreeImpl() to pymalloc_free() * Rename _PyObject_Realloc() to pymalloc_realloc() * pymalloc_alloc() and pymalloc_realloc() don't fallback on the raw allocator anymore, it now must be done by the caller * Add "success" and "failed" labels to pymalloc_alloc() and pymalloc_free() * pymalloc_alloc() and pymalloc_free() don't update num_allocated_blocks anymore: it should be done in the caller * _PyObject_Calloc() is now responsible to fill the memory block allocated by pymalloc with zeros * Simplify pymalloc_alloc() prototype * _PyObject_Realloc() now calls _PyObject_Malloc() rather than calling directly pymalloc_alloc() _PyMem_DebugRawAlloc() and _PyMem_DebugRawRealloc(): * document the layout of a memory block * don't increase the serial number if the allocation failed * check for integer overflow before computing the total size * add a 'data' variable to make the code easiler to follow test_setallocators() of _testcapimodule.c now test also the context.

* bpo-31173: Rewrite WSTOPSIG test of test_subprocess (#3055)Victor Stinner2017-08-101-0/+22
| | | | | | | | | | | | | The current test_child_terminated_in_stopped_state() function test creates a child process which calls ptrace(PTRACE_TRACEME, 0, 0) and then crash (SIGSEGV). The problem is that calling os.waitpid() in the parent process is not enough to close the process: the child process remains alive and so the unit test leaks a child process in a strange state. Closing the child process requires non-trivial code, maybe platform specific. Remove the functional test and replaces it with an unit test which mocks os.waitpid() using a new _testcapi.W_STOPCODE() function to test the WIFSTOPPED() path.

* bpo-30039: Don't run signal handlers while resuming a yield from stack (#1081)Nathaniel J. Smith2017-05-171-0/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If we have a chain of generators/coroutines that are 'yield from'ing each other, then resuming the stack works like: - call send() on the outermost generator - this enters _PyEval_EvalFrameDefault, which re-executes the YIELD_FROM opcode - which calls send() on the next generator - which enters _PyEval_EvalFrameDefault, which re-executes the YIELD_FROM opcode - ...etc. However, every time we enter _PyEval_EvalFrameDefault, the first thing we do is to check for pending signals, and if there are any then we run the signal handler. And if it raises an exception, then we immediately propagate that exception *instead* of starting to execute bytecode. This means that e.g. a SIGINT at the wrong moment can "break the chain" – it can be raised in the middle of our yield from chain, with the bottom part of the stack abandoned for the garbage collector. The fix is pretty simple: there's already a special case in _PyEval_EvalFrameEx where it skips running signal handlers if the next opcode is SETUP_FINALLY. (I don't see how this accomplishes anything useful, but that's another story.) If we extend this check to also skip running signal handlers when the next opcode is YIELD_FROM, then that closes the hole – now the exception can only be raised at the innermost stack frame. This shouldn't have any performance implications, because the opcode check happens inside the "slow path" after we've already determined that there's a pending signal or something similar for us to process; the vast majority of the time this isn't true and the new check doesn't run at all.
