* bpo-46541: Replace core use of _Py_IDENTIFIER() with statically initialized ↵Eric Snow2022-02-081-5/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | global objects. (gh-30928) We're no longer using _Py_IDENTIFIER() (or _Py_static_string()) in any core CPython code. It is still used in a number of non-builtin stdlib modules. The replacement is: PyUnicodeObject (not pointer) fields under _PyRuntimeState, statically initialized as part of _PyRuntime. A new _Py_GET_GLOBAL_IDENTIFIER() macro facilitates lookup of the fields (along with _Py_GET_GLOBAL_STRING() for non-identifier strings). https://bugs.python.org/issue46541#msg411799 explains the rationale for this change. The core of the change is in: * (new) Include/internal/pycore_global_strings.h - the declarations for the global strings, along with the macros * Include/internal/pycore_runtime_init.h - added the static initializers for the global strings * Include/internal/pycore_global_objects.h - where the struct in pycore_global_strings.h is hooked into _PyRuntimeState * Tools/scripts/generate_global_objects.py - added generation of the global string declarations and static initializers I've also added a --check flag to generate_global_objects.py (along with make check-global-objects) to check for unused global strings. That check is added to the PR CI config. The remainder of this change updates the core code to use _Py_GET_GLOBAL_IDENTIFIER() instead of _Py_IDENTIFIER() and the related _Py*Id functions (likewise for _Py_GET_GLOBAL_STRING() instead of _Py_static_string()). This includes adding a few functions where there wasn't already an alternative to _Py*Id(), replacing the _Py_Identifier * parameter with PyObject *. The following are not changed (yet): * stop using _Py_IDENTIFIER() in the stdlib modules * (maybe) get rid of _Py_IDENTIFIER(), etc. entirely -- this may not be doable as at least one package on PyPI using this (private) API * (maybe) intern the strings during runtime init https://bugs.python.org/issue46541
* bpo-46670: Define all macros for stringlib (GH-31176)Victor Stinner2022-02-071-0/+1
| | | | | bytesobject.c, bytearrayobject.c and unicodeobject.c now define all macros used by stringlib, to avoid using undefined macros. Fix "gcc -Wundef" warnings.
* bpo-45434: Remove pystrhex.h header file (GH-28923)Victor Stinner2021-10-131-2/+2
| | | | | | | | | | | | | | | Move Include/pystrhex.h to Include/internal/pycore_strhex.h. The header file only contains private functions. The following C extensions are now built with Py_BUILD_CORE_MODULE macro defined to get access to the internal C API: * _blake2 * _hashopenssl * _md5 * _sha1 * _sha3 * _ssl * binascii

* bpo-42979: Use _Py_CheckSlotResult() to check slots result (GH-24356)Victor Stinner2021-01-291-4/+6
| | | | | | | | | | | | | | | When Python is built in debug mode (with C assertions), calling a type slot like sq_length (__len__() in Python) now fails with a fatal error if the slot succeeded with an exception set, or failed with no exception set. The error message contains the slot, the type name, and the current exception (if an exception is set). * Check the result of all slots using _Py_CheckSlotResult(). * No longer pass op_name to ternary_op() in release mode. * Replace operator with dunder Python method name in error messages. For example, replace "*" with "__mul__". * Fix compiler_exit_scope() when an exception is set. * Fix bytearray.extend() when an exception is set: don't call bytearray_setslice() with an exception set.
* bpo-42924: Fix incorrect copy in bytearray_repeat (GH-24208)Tobias Holl2021-01-131-2/+4
| | | | Before, using the * operator to repeat a bytearray would copy data from the start of the internal buffer (ob_bytes) and not from the start of the actual data (ob_start).
* bpo-42431: Fix outdated bytes comments (GH-23458)Serhiy Storchaka2020-12-031-10/+7
| | | | Also move definitions of internal macros F_LJUST etc to private header.
* bpo-42435: Speed up comparison of bytes and bytearray object (GH--23461)Serhiy Storchaka2020-11-221-12/+8
| | | | | * Speed up comparison of bytes objects with non-bytes objects when option -b is specified. * Speed up comparison of bytarray objects with non-buffer object.
* bpo-41334: Convert constructors of str, bytes and bytearray to Argument ↵Serhiy Storchaka2020-07-201-11/+13

* bpo-41175: Guard against a NULL pointer dereference within bytearrayobject ↵stratakis2020-07-081-1/+3
| | | | | | | (GH-21240) The issue is triggered by the bytearray() + bytearray() operation. Detected by GCC 10 static analysis tool.
* bpo-37999: Simplify the conversion code for %c, %d, %x, etc. (GH-20437)Serhiy Storchaka2020-06-291-13/+6
| | | | Since PyLong_AsLong() no longer use __int__, explicit call of PyNumber_Index() before it is no longer needed.
* bpo-39939: Add str.removeprefix and str.removesuffix (GH-18939)sweeneyde2020-04-221-0/+67
| | | | | Added str.removeprefix and str.removesuffix methods and corresponding bytes, bytearray, and collections.UserString methods to remove affixes from a string if present. See PEP 616 for a full description.
* bpo-40268: Remove unused pycore_pymem.h includes (GH-19531)Victor Stinner2020-04-151-1/+0
|
* bpo-40268: Remove unused structmember.h includes (GH-19530)Victor Stinner2020-04-151-2/+1
| | | | | | If only offsetof() is needed: include stddef.h instead. When structmember.h is used, add a comment explaining that PyMemberDef is used.
* bpo-40268: Add _PyInterpreterState_GetConfig() (GH-19492)Victor Stinner2020-04-131-5/+2
| | | | | | | | Don't access PyInterpreterState.config member directly anymore, but use new functions: * _PyInterpreterState_GetConfig() * _PyInterpreterState_SetConfig() * _Py_GetConfig()
* bpo-40170: Add _PyIndex_Check() internal function (GH-19426)Victor Stinner2020-04-081-3/+4
| | | | | | | | | Add _PyIndex_Check() function to the internal C API: fast inlined verson of PyIndex_Check(). Add Include/internal/pycore_abstract.h header file. Replace PyIndex_Check() with _PyIndex_Check() in C files of Objects and Python subdirectories.
* bpo-35081: Move bytes_methods.h to the internal C API (GH-18492)Victor Stinner2020-02-121-1/+1
| | | | | Move the bytes_methods.h header file to the internal C API as pycore_bytes_methods.h: it only contains private symbols (prefixed by "_Py"), except of the PyDoc_STRVAR_shared() macro.
* bpo-39245: Switch to public API for Vectorcall (GH-18460)Petr Viktorin2020-02-111-2/+2

* bpo-39573: Use Py_SET_SIZE() function (GH-18402)Victor Stinner2020-02-071-5/+5
| | | | Replace direct acccess to PyVarObject.ob_size with usage of the Py_SET_SIZE() function.
* bpo-39573: Use Py_TYPE() macro in Objects directory (GH-18392)Victor Stinner2020-02-071-2/+2
| | | Replace direct access to PyObject.ob_type with Py_TYPE().

* bpo-22385: Support output separators in hex methods. (#13578)Gregory P. Smith2019-05-291-8/+26
| | | | | | | | | | | | | | | | | | * bpo-22385: Support output separators in hex methods. Also in binascii.hexlify aka b2a_hex. The underlying implementation behind all hex generation in CPython uses the same pystrhex.c implementation. This adds support to bytes, bytearray, and memoryview objects. The binascii module functions exist rather than being slated for deprecation because they return bytes rather than requiring an intermediate step through a str object. This change was inspired by MicroPython which supports sep in its binascii implementation (and does not yet support the .hex methods). https://bugs.python.org/issue22385
* bpo-36763: Implement the PEP 587 (GH-13592)Victor Stinner2019-05-271-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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-36946: Fix possible signed integer overflow when handling slices. (GH-13375)Zackery Spytz2019-05-171-1/+2
| | | | | | | The final addition (cur += step) may overflow, so use size_t for "cur". "cur" is always positive (even for negative steps), so it is safe to use size_t here. Co-Authored-By: Martin Panter <vadmium+py@gmail.com>
* bpo-36900: Replace global conf vars with config (GH-13299)Victor Stinner2019-05-141-2/+4
| | | | | | Replace global configuration variables with core_config read from the current interpreter. Cleanup dynload_hpux.c.
* bpo-35713: Rework Python initialization (GH-11647)Victor Stinner2019-01-221-11/+0
| | | | | | | | | | | | | | | | | | | * The PyByteArray_Init() and PyByteArray_Fini() functions have been removed. They did nothing since Python 2.7.4 and Python 3.2.0, were excluded from the limited API (stable ABI), and were not documented. * Move "_PyXXX_Init()" and "_PyXXX_Fini()" declarations from Include/cpython/pylifecycle.h to Include/internal/pycore_pylifecycle.h. Replace "PyAPI_FUNC(TYPE)" with "extern TYPE". * _PyExc_Init() now returns an error on failure rather than calling Py_FatalError(). Move macros inside _PyExc_Init() and undefine them when done. Rewrite macros to make them look more like statement: add ";" when using them, add "do { ... } while (0)". * _PyUnicode_Init() now returns a _PyInitError error rather than call Py_FatalError(). * Move stdin check from _PySys_BeginInit() to init_sys_streams(). * _Py_ReadyTypes() now returns a _PyInitError error rather than calling Py_FatalError().
* bpo-35444: Unify and optimize the helper for getting a builtin object. ↵Serhiy Storchaka2018-12-111-2/+3
| | | | | | | | (GH-11047) This speeds up pickling of some iterators. This fixes also error handling in pickling methods when fail to look up builtin "getattr".
* bpo-35081: Add Include/internal/pycore_object.h (GH-10640)Victor Stinner2018-11-211-0/+1
| | | | Move _PyObject_GC_TRACK() and _PyObject_GC_UNTRACK() from Include/objimpl.h to Include/internal/pycore_object.h.
* bpo-35081: Rename internal headers (GH-10275)Victor Stinner2018-11-121-2/+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-35081: Add pycore_ prefix to internal header files (GH-10263)Victor Stinner2018-10-311-2/+2
| | | | | | | | | | | | | | | | | | | | * 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-34984: Improve error messages for bytes and bytearray constructors. ↵Serhiy Storchaka2018-10-211-4/+20
| | | | (GH-9874)
* bpo-34974: Do not replace unexpected errors in bytes() and bytearray(). ↵Serhiy Storchaka2018-10-141-2/+1
| | | | | | | (GH-9852) bytes and bytearray constructors converted unexpected exceptions (e.g. MemoryError and KeyboardInterrupt) to TypeError.
* bpo-34170: Add _PyCoreConfig.bytes_warning (GH-8447)Victor Stinner2018-07-241-5/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add more fields to _PyCoreConfig: * _check_hash_pycs_mode * bytes_warning * debug * inspect * interactive * legacy_windows_fs_encoding * legacy_windows_stdio * optimization_level * quiet * unbuffered_stdio * user_site_directory * verbose * write_bytecode Changes: * Remove pymain_get_global_config() and pymain_set_global_config() which became useless. These functions have been replaced by _PyCoreConfig_GetGlobalConfig() and _PyCoreConfig_SetGlobalConfig(). * sys.flags.dont_write_bytecode value is now restricted to 1 even if -B option is specified multiple times on the command line. * PyThreadState_Clear() now uses the config from the current interpreter rather than using global Py_VerboseFlag
* bpo-20180: complete AC conversion of Objects/stringlib/transmogrify.h (GH-8039)Tal Einat2018-07-061-6/+5
| | | | * converted bytes methods: expandtabs, ljust, rjust, center, zfill * updated char_convertor to properly set the C default value
* bpo-33012: Fix invalid function cast warnings with gcc 8 for METH_NOARGS. ↵Siddhesh Poyarekar2018-04-291-17/+17
| | | | | | | | | (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.
* bpo-32677: Add .isascii() to str, bytes and bytearray (GH-5342)INADA Naoki2018-01-271-0/+2
