* bpo-40939: Rename PyPegen* functions to PyParser* (GH-21016)Lysandros Nikolaou2020-06-211-0/+1
| | | | | | Rename PyPegen* functions to PyParser*, so that we can remove the old set of PyParser* functions that were using the old parser.
* bpo-40421: Add Include/cpython/code.h header file (GH-19756)Victor Stinner2020-04-281-0/+1
| | | | | | | | | | | bpo-35134, bpo-40421: Add Include/cpython/code.h header file. code.h now defines PyCodeObject type in the limited C API. It is now included by Python.h. Give a name to the PyCodeObject structure: it is now called "struct PyCodeObject". So it becomes possible to define PyCodeObject as "struct PyCodeObject" in the limited C API without defining the structure.
* bpo-40421: Add pyframe.h header file (GH-19755)Victor Stinner2020-04-281-0/+1
| | | | | | | | | | Add a new separated pyframe.h header file of the PyFrame public C API: it is included by Python.h. Add PyFrame_GetLineNumber() to the limited C API. Replace "struct _frame" with "PyFrameObject" in header files. PyFrameObject is now defined as struct _frame by pyframe.h which is included early enough in Python.h.
* bpo-40268: Remove explicit pythread.h includes (#19529)Victor Stinner2020-04-151-0/+1
| | | | Remove explicit pythread.h includes: it is always included by Python.h.
* bpo-39481: Implementation for PEP 585 (#18239)Guido van Rossum2020-04-071-0/+1
| | | | | | | | | | | | This implements things like `list[int]`, which returns an object of type `types.GenericAlias`. This object mostly acts as a proxy for `list`, but has attributes `__origin__` and `__args__` that allow recovering the parts (with values `list` and `(int,)`. There is also an approximate notion of type variables; e.g. `list[T]` has a `__parameters__` attribute equal to `(T,)`. Type variables are objects of type `typing.TypeVar`.
* bpo-35081: Move dtoa.h header to the internal C API (GH-18489)Victor Stinner2020-02-121-1/+0
| | | | | | | Move the dtoa.h header file to the internal C API as pycore_dtoa.h: it only contains private functions (prefixed by "_Py"). The math and cmath modules must now be compiled with the Py_BUILD_CORE macro defined.
* bpo-36763: Implement the PEP 587 (GH-13592)Victor Stinner2019-05-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Add a whole new documentation page: "Python Initialization Configuration" * PyWideStringList_Append() return type is now PyStatus, instead of int * PyInterpreterState_New() now calls PyConfig_Clear() if PyConfig_InitPythonConfig() fails. * Rename files: * Python/coreconfig.c => Python/initconfig.c * Include/cpython/coreconfig.h => Include/cpython/initconfig.h * Include/internal/: pycore_coreconfig.h => pycore_initconfig.h * Rename structures * _PyCoreConfig => PyConfig * _PyPreConfig => PyPreConfig * _PyInitError => PyStatus * _PyWstrList => PyWideStringList * Rename PyConfig fields: * use_module_search_paths => module_search_paths_set * module_search_path_env => pythonpath_env * Rename PyStatus field: _func => func * PyInterpreterState: rename core_config field to config * Rename macros and functions: * _PyCoreConfig_SetArgv() => PyConfig_SetBytesArgv() * _PyCoreConfig_SetWideArgv() => PyConfig_SetArgv() * _PyCoreConfig_DecodeLocale() => PyConfig_SetBytesString() * _PyInitError_Failed() => PyStatus_Exception() * _Py_INIT_ERROR_TYPE_xxx enums => _PyStatus_TYPE_xxx * _Py_UnixMain() => Py_BytesMain() * _Py_ExitInitError() => Py_ExitStatusException() * _Py_PreInitializeFromArgs() => Py_PreInitializeFromBytesArgs() * _Py_PreInitializeFromWideArgs() => Py_PreInitializeFromArgs() * _Py_PreInitialize() => Py_PreInitialize() * _Py_RunMain() => Py_RunMain() * _Py_InitializeFromConfig() => Py_InitializeFromConfig() * _Py_INIT_XXX() => _PyStatus_XXX() * _Py_INIT_FAILED() => _PyStatus_EXCEPTION() * Rename 'err' PyStatus variables to 'status' * Convert RUN_CODE() macro to config_run_code() static inline function * Remove functions: * _Py_InitializeFromArgs() * _Py_InitializeFromWideArgs() * _PyInterpreterState_GetCoreConfig()

* bpo-36142: Exclude coreconfig.h from Py_LIMITED_API (GH-12111)Victor Stinner2019-03-011-1/+1
| | | | | | | | | The whole coreconfig.h header is now excluded from Py_LIMITED_API. Move functions definitions into a new internal pycore_coreconfig.h header. * Move Include/coreconfig.h to Include/cpython/coreconfig.h * coreconfig.h header is now excluded from Py_LIMITED_API * Move functions to pycore_coreconfig.h
* bpo-28503: Use crypt_r() when available instead of crypt() (GH-11373)Gregory P. Smith2018-12-301-0/+10
| | | | | Use crypt_r() when available instead of crypt() in the crypt module. As a nice side effect: This also avoids a memory sanitizer flake as clang msan doesn't know about crypt's internal libc allocated buffer.
* 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: Move Include/pyatomic.c to Include/internal/ (GH-10239)Victor Stinner2018-10-301-2/+0
| | | Add pyatomic.h to the VS project (it wasn't referenced).
* bpo-35053: Add Include/tracemalloc.h (GH-10091)Victor Stinner2018-10-251-0/+1
| | | | | | | * 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-34674: Assume unistd.h exists on Unix. (GH-9290)Benjamin Peterson2018-09-141-1/+1

* bpo-34170: Add Python/coreconfig.c for _PyCoreConfig (GH-8607)Victor Stinner2018-08-011-0/+1
| | | | | | | * Add Include/coreconfig.h * Move config_*() and _PyCoreConfig_*() functions from Modules/main.c to a new Python/coreconfig.c file. * Inline _Py_ReadHashSeed() into config_init_hash_seed() * Move global configuration variables to coreconfig.c
* bpo-32635: Fix a segfault when importing the crypt module with libxcrypt. ↵stratakis2018-01-231-0/+3
| | | | | | | (#5284) glibc is deprecating libcrypt in favor of libxcrypt, however python assumes that crypt.h will always be included. This change makes the header inclusion explicit when libxcrypt is present on the system.

* bpo-30860: Consolidate stateful runtime globals. (#2594)Eric Snow2017-09-061-0/+4
| | | | | | | | | * group the (stateful) runtime globals into various topical structs * consolidate the topical structs under a single top-level _PyRuntimeState struct * add a check-c-globals.py script that helps identify runtime globals Other globals are excluded (see globals.txt and check-c-globals.py).
* bpo-22257: Small changes for PEP 432. (#1728)Eric Snow2017-05-231-1/+1
| | | PEP 432 specifies a number of large changes to interpreter startup code, including exposing a cleaner C-API. The major changes depend on a number of smaller changes. This patch includes all those smaller changes.

Reasons for the change: a) Make the comment more explicit. b) If char is unsigned, the cast is optimized away. c) If char is unsigned, gcc emits spurious "array subscript has type 'char'" warnings.
* Make (most of) Python's tests pass under Thread Sanitizer.Jeffrey Yasskin2010-05-031-0/+2
| | | | | | | | | | | | | | | | | | http://code.google.com/p/data-race-test/wiki/ThreadSanitizer is a dynamic data race detector that runs on top of valgrind. With this patch, the binaries at http://code.google.com/p/data-race-test/wiki/ThreadSanitizer#Binaries pass many but not all of the Python tests. All of regrtest still passes outside of tsan. I've implemented part of the C1x atomic types so that we can explicitly mark variables that are used across threads, and get defined behavior as compilers advance. I've added tsan's client header and implementation to the codebase in dynamic_annotations.{h,c} (docs at http://code.google.com/p/data-race-test/wiki/DynamicAnnotations). Unfortunately, I haven't been able to get helgrind and drd to give sensible error messages, even when I use their client annotations, so I'm not supporting them.
