* bpo-45459: C API uses type names rather than structure names (GH-31528)Victor Stinner2022-02-241-3/+3
| | | | Thanks to the new pytypedefs.h, it becomes to use type names like PyObject rather like structure names like "struct _object".
* bpo-45459: Add pytypedefs.h header file (GH-31527)Victor Stinner2022-02-241-10/+0
| | | | | | | | | | | | | | | | | | Move forward declarations of Python C API types to a new pytypedefs.h header file to solve interdependency issues between header files. pytypedefs.h contains forward declarations of the following types: * PyCodeObject * PyFrameObject * PyGetSetDef * PyInterpreterState * PyLongObject * PyMemberDef * PyMethodDef * PyModuleDef * PyObject * PyThreadState * PyTypeObject
* bpo-45434: Remove useless space in includes (GH-28963)Victor Stinner2021-10-141-1/+1
| | | Micro-optimize spaces!
* pycore_pystate.h no longer redefines PyThreadState_GET() (GH-28921)Victor Stinner2021-10-131-10/+2
| | | | | | | | | | | | | | | | | | | | | | Redefining the PyThreadState_GET() macro in pycore_pystate.h is useless since it doesn't affect files not including it. Either use _PyThreadState_GET() directly, or don't use pycore_pystate.h internal C API. For example, the _testcapi extension don't use the internal C API, but use the public PyThreadState_Get() function instead. Replace PyThreadState_Get() with _PyThreadState_GET(). The _PyThreadState_GET() macro is more efficient than PyThreadState_Get() and PyThreadState_GET() function calls which call fail with a fatal Python error. posixmodule.c and _ctypes extension now include <windows.h> before pycore header files (like pycore_call.h). _PyTraceback_Add() now uses _PyErr_Fetch()/_PyErr_Restore() instead of PyErr_Fetch()/PyErr_Restore(). The _decimal and _xxsubinterpreters extensions are now built with the Py_BUILD_CORE_MODULE macro defined to get access to the internal C API.
* Update code comment re: location of struct _is. (GH-20067)Chris Jerdonek2020-05-151-1/+1

* bpo-40421: Add pyframe.h header file (GH-19755)Victor Stinner2020-04-281-2/+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 Stinner2020-04-151-2/+0
| | | | Remove explicit pythread.h includes: it is always included by Python.h.

| | | | Add PyThreadState_GetInterpreter(tstate): get the interpreter of a Python thread state.
* bpo-39947: Add PyInterpreterState_Get() function (GH-18979)Victor Stinner2020-03-131-0/+11
| | | | | | * Rename _PyInterpreterState_Get() to PyInterpreterState_Get() and move it the limited C API. * Add _PyInterpreterState_Get() alias to PyInterpreterState_Get() for backward compatibility with Python 3.8.
* bpo-37878: Remove PyThreadState_DeleteCurrent() function (GH-15315)Joannah Nanjekye2019-09-051-1/+0
| | | | | | | * Rename PyThreadState_DeleteCurrent() to _PyThreadState_DeleteCurrent() * Move it to the internal C API Co-Authored-By: Carol Willing <carolcode@willingconsulting.com>
* bpo-36124: Add PyInterpreterState.dict. (gh-12132)Eric Snow2019-03-151-2/+8

* bpo-36142: Exclude coreconfig.h from Py_LIMITED_API (GH-12111)Victor Stinner2019-03-011-1/+0
| | | | | | | | | 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-35886: Make PyInterpreterState an opaque type in the public API. (GH-11731)Eric Snow2019-02-231-14/+12
| | | Move PyInterpreterState into the "internal" header files.
* bpo-35134: Don't define types twice in header files (GH-10754)Victor Stinner2018-11-271-17/+20
| | | | | | Fix the following clang warning: Include/cpython/pystate.h:217:3: warning: redefinition of typedef 'PyThreadState' is a C11 feature [-Wtypedef-redefinition]
* bpo-35134: Create Include/cpython/pystate.h (GH-10733)Victor Stinner2018-11-261-281/+3
| | | | Move pystate.h code surrounded by "#ifndef Py_LIMITED_API" to a new Include/cpython/pystate.h header file.
* bpo-35081: Rename internal headers (GH-10275)Victor Stinner2018-11-121-1/+1
| | | | | | | | | | | | | | 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 _PyThreadState_GET() internal macro (GH-10266)Victor Stinner2018-11-011-25/+31
| | | | | | | | | | | | | | | | | | | | | | | | | 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 Stinner2018-10-311-1/+1
| | | | | | | | | | | | | | | | | | | | * 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: 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-34523: Use _PyCoreConfig instead of globals (GH-9005)Victor Stinner2018-08-291-2/+6
| | | | | Use the core configuration of the interpreter, rather than using global configuration variables. For example, replace Py_QuietFlag with core_config->quiet.
* bpo-34301: Add _PyInterpreterState_Get() helper function (GH-8592)Victor Stinner2018-08-031-0/+7
| | | | sys_setcheckinterval() now uses a local variable to parse arguments, before writing into interp->check_interval.
* bpo-34170: Add Python/coreconfig.c for _PyCoreConfig (GH-8607)Victor Stinner2018-08-011-255/+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-34170: Rename _PyCoreConfig.unbuffered_stdip (GH-8594)Victor Stinner2018-08-011-8/+8
| | | | * Rename _PyCoreConfig.unbuffered_stdio to buffered_stdio * Rename _PyCoreConfig.debug to parser_debug
* bpo-34170: Add _PyCoreConfig._frozen parameter (GH-8591)Victor Stinner2018-08-011-1/+8
| | | Modify frozenmain.c to use _Py_InitializeFromConfig().
* bpo-34170, test_embed: write Py_Initialize() tests (GH-8484)Victor Stinner2018-07-261-1/+6
|
* bpo-34170: Cleanup pymain_read_conf() (GH-8476)Victor Stinner2018-07-261-2/+7
| | | | | | | | | | * Config: Rename ignore_environment field to use_environment. * _PyCoreConfig_Read(): if isolated is set, use_environment and site_import are now always set to 0. * Inline pymain_free_raw() into pymain_free() * Move config_init_warnoptions() call into pymain_read_conf_impl() * _PyCoreConfig_Read(): don't replace values if they are already set: faulthandler, pycache_prefix, home.
* bpo-34170: Enhance _PyCoreConfig_Read() (GH-8468)Victor Stinner2018-07-261-5/+14
| | | | | | | | | | | | * Inline cmdline_get_env_flags() into config_read_env_vars(): _PyCoreConfig_Read() now reads much more environment variables like PYTHONVERBOSE. * Allow to override faulthandler and allocator even if dev_mode=1. PYTHONMALLOC is now the priority over PYTHONDEVMODE. * Fix _PyCoreConfig_Copy(): copy also install_signal_handlers, coerce_c_locale and coerce_c_locale_warn * _PyCoreConfig.install_signal_handlers default is now 1: install signals by default * Fix also a compiler warning: don't define _PyPathConfig type twice.
* bpo-34228: Allow PYTHONTRACEMALLOC=0 (GH-8467)Victor Stinner2018-07-251-0/+1
| | | | | PYTHONTRACEMALLOC=0 environment variable and -X tracemalloc=0 command line option are now allowed to disable explicitly tracemalloc at startup.
* bpo-34170: Add _Py_InitializeFromConfig() (GH-8454)Victor Stinner2018-07-251-2/+1
| | | | | | | | | | | | | | * If _Py_InitializeCore() is called twice, the second call now copies and apply (partially) the new configuration. * Rename _Py_CommandLineDetails to _PyCmdline * Move more code into pymain_init(). The core configuration created by Py_Main() is new destroyed before running Python to reduce the memory footprint. * _Py_InitializeCore() now returns the created interpreter. _Py_InitializeMainInterpreter() now expects an interpreter. * Remove _Py_InitializeEx_Private(): _freeze_importlib now uses _Py_InitializeFromConfig() * _PyCoreConfig_InitPathConfig() now only computes the path configuration if needed.
* bpo-34170: Add _PyCoreConfig.bytes_warning (GH-8447)Victor Stinner2018-07-241-2/+142
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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-34170: Add _PyCoreConfig.isolated (GH-8417)Victor Stinner2018-07-241-4/+28
| | | | | | | | | | | | | | | * _PyCoreConfig: add isolated and site_import attributes * Replace Py_IgnoreEnvironment with config->ignore_environment when reading the current configuration * _PyCoreConfig_Read() now sets ignore_environment, utf8_mode, isolated and site_import from Py_IgnoreEnvironment, Py_UTF8Mode, Py_IsolatedFlag and Py_NoSiteFlag * _Py_InitializeCore() now sets Py_xxx flags from the configuration * pymain_read_conf() now uses _PyCoreConfig_Copy() to save/restore the configuration. * Rename _disable_importlib of _PyCoreConfig to _install_importlib * _PyCoreConfig_SetGlobalConfig() now also set Py_HashRandomizationFlag * Replace !Py_NoSiteFlag with core_config->site_import
* bpo-34170: Rework _PyCoreConfig_Read() to avoid side effect (GH-8353)Victor Stinner2018-07-211-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | Rework _PyCoreConfig_Read() function which *reads* core configuration to not *modify* the path configuration. A new _PyCoreConfig_SetPathConfig() function now recreates the path configuration from the core configuration. This function is now called very late in _Py_InitializeCore(), just before calling initimport(). Changes: * Add _PyCoreConfig.dll_path * Py_SetPath() now fails with a fatal python error on memory allocation failure. * Rename _PyPathConfig_Calculate() to _PyPathConfig_Calculate_impl() * Replace _PyPathConfig_Init() with _PyPathConfig_Calculate(): the function now requires a _PyPathConfig * Add _PyPathConfig_SetGlobal() to set the _Py_path_config global variable. * Add _PyCoreConfig_InitPathConfig(): compute the path configuration * Add _PyCoreConfig_SetPathConfig(): set path configuration from core configuration * Rename wstrlist_append() to _Py_wstrlist_append() * _Py_wstrlist_append() now handles integer overflow.
* bpo-33499: Add PYTHONPYCACHEPREFIX env var for alt bytecode cache location. ↵Carl Meyer2018-06-161-1/+2
| | | | | | | | | | | | | | | (GH-6834) In some development setups it is inconvenient or impossible to write bytecode caches to the code tree, but the bytecode caches are still useful. The PYTHONPYCACHEPREFIX environment variable allows specifying an alternate location for cached bytecode files, within which a directory tree mirroring the code tree will be created. This cache tree is then used (for both reading and writing) instead of the local `__pycache__` subdirectory within each source directory. Exposed at runtime as sys.pycache_prefix (defaulting to None), and can be set from the CLI as "-X pycache_prefix=path". Patch by Carl Meyer.
* bpo-32604: Clean up created subinterpreters before runtime finalization. ↵Eric Snow2018-02-171-0/+4
| | | | | | (gh-5709)
* bpo-32030: Add _PyCoreConfig.module_search_paths (#4954)Victor Stinner2018-01-241-13/+27
| | | | | | | | | | | _PyCoreConfig_Read() is now responsible to compute sys.path. So sys.path is now computed before calling _Py_InitializeCore(). Changes: * Add module_search_path, module_search_paths, executable, prefix, base_prefix, exec_prefix and base_exec_prefix to _PyCoreConfig. * _PyMainInterpreterConfig_Read() now only converts wchar_t** lists into a Python list, it doesn't compute sys.path anymore.
* bpo-32436: Implement PEP 567 (#5027)Yury Selivanov2018-01-231-0/+8

* bpo-32591: Add native coroutine origin tracking (#5250)Nathaniel J. Smith2018-01-211-0/+2
| | | | | | * Add coro.cr_origin and sys.set_coroutine_origin_tracking_depth * Use coroutine origin information in the unawaited coroutine warning * Stop using set_coroutine_wrapper in asyncio debug mode * In BaseEventLoop.set_debug, enable debugging in the correct thread
* bpo-32030: Complete _PyCoreConfig_Read() (#4946)Victor Stinner2017-12-201-1/+3
| | | | | | | | | | * Add _PyCoreConfig.install_signal_handlers * Remove _PyMain.config: _PyMainInterpreterConfig usage is now restricted to pymain_init_python_main(). * Rename _PyMain.core_config to _PyMain.config * _PyMainInterpreterConfig_Read() now creates the xoptions dictionary from the core config * Fix _PyMainInterpreterConfig_Read(): don't replace xoptions and argv if they are already set.
* bpo-32030: Add _PyCoreConfig.warnoptions (#4936)Victor Stinner2017-12-201-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Merge _PyCoreConfig_ReadEnv() into _PyCoreConfig_Read(), and _Py_CommandLineDetails usage is now restricted to pymain_cmdline(). Changes: * _PyCoreConfig: Add nxoption, xoptions, nwarnoption and warnoptions * Add _PyCoreConfig.program: argv[0] or "" * Move filename, command, module and xoptions from _Py_CommandLineDetails to _PyMain. xoptions _Py_OptList becomes (int, wchar_t**) list. * Add pymain_cmdline() function * Rename copy_argv() to copy_wstrlist(). Rename clear_argv() to clear_wstrlist(). Remove _Py_OptList structure: use (int, wchar_t**) list instead. * Rename pymain_set_flag_from_env() to pymain_get_env_flag() * Rename pymain_set_flags_from_env() to pymain_get_env_flags() * _PyMainInterpreterConfig_Read() now creates the warnoptions from _PyCoreConfig.warnoptions * Inline pymain_add_warning_dev_mode() and pymain_add_warning_bytes_flag() into config_init_warnoptions() * Inline pymain_get_program_name() into _PyCoreConfig_Read() * _Py_CommandLineDetails: Replace warning_options with nwarnoption and warnoptions. Replace env_warning_options with nenv_warnoption and env_warnoptions. * pymain_warnings_envvar() now has a single implementation for Windows and Unix: use config_get_env_var_dup() to also get the variable as wchar_t* on Unix.
* bpo-31901: atexit callbacks should be run at subinterpreter shutdown (#4611)Marcel Plch2017-12-201-0/+3

* bpo-32030: Add _PyCoreConfig.argv (#4934)Victor Stinner2017-12-191-1/+9
| | | | | | | * Add argc and argv to _PyCoreConfig * _PyMainInterpreterConfig_Read() now builds its argv from _PyCoreConfig.arg * Move _PyMain.env_warning_options into _Py_CommandLineDetails * Reorder pymain_free()
* bpo-29240, bpo-32030: Py_Main() re-reads config if encoding changes (#4899)Victor Stinner2017-12-161-2/+6
| | | | | | | | | | | | | | | | | | bpo-29240, bpo-32030: If the encoding change (C locale coerced or UTF-8 Mode changed), Py_Main() now reads again the configuration with the new encoding. Changes: * Add _Py_UnixMain() called by main(). * Rename pymain_free_pymain() to pymain_clear_pymain(), it can now be called multipled times. * Rename pymain_parse_cmdline_envvars() to pymain_read_conf(). * Py_Main() now clears orig_argc and orig_argv at exit. * Remove argv_copy2, Py_Main() doesn't modify argv anymore. There is no need anymore to get two copies of the wchar_t** argv. * _PyCoreConfig: add coerce_c_locale and coerce_c_locale_warn. * Py_UTF8Mode is now initialized to -1. * Locale coercion (PEP 538) now respects -I and -E options.
* bpo-32030: Add _PyMainInterpreterConfig.executable (#4876)Victor Stinner2017-12-151-6/+9
| | | | | | | | | | | | * Add new fields to _PyMainInterpreterConfig: * executable * prefix * base_prefix * exec_prefix * base_exec_prefix * _PySys_EndInit() now sets sys attributes from _PyMainInterpreterConfig
* bpo-32030: Add _PyMainInterpreterConfig.warnoptions (#4855)Victor Stinner2017-12-141-0/+2
| | | Add warnoptions and xoptions fields to _PyMainInterpreterConfig.

| | | | | | | | | | | | | | | | | | | | _PyMainInterpreterConfig now contains Python objects, whereas _PyCoreConfig contains wchar_t* strings. Core config: * Rename _PyMainInterpreterConfig_ReadEnv() to _PyCoreConfig_ReadEnv() * Move 3 strings from _PyMainInterpreterConfig to _PyCoreConfig: module_search_path_env, home, program_name. * Add _PyCoreConfig_Clear() * _PyPathConfig_Calculate() now takes core config rather than main config * _PyMainInterpreterConfig_Read() now requires also a core config Main config: * Add _PyMainInterpreterConfig.module_search_path: sys.path list * Add _PyMainInterpreterConfig.argv: sys.argv list * _PyMainInterpreterConfig_Read() now computes module_search_path
* bpo-29240: PEP 540: Add a new UTF-8 Mode (#855)Victor Stinner2017-12-131-0/+1
| | | | | | | | | | | | | | | | | | | | | | * Add -X utf8 command line option, PYTHONUTF8 environment variable and a new sys.flags.utf8_mode flag. * If the LC_CTYPE locale is "C" at startup: enable automatically the UTF-8 mode. * Add _winapi.GetACP(). encodings._alias_mbcs() now calls _winapi.GetACP() to get the ANSI code page * locale.getpreferredencoding() now returns 'UTF-8' in the UTF-8 mode. As a side effect, open() now uses the UTF-8 encoding by default in this mode. * Py_DecodeLocale() and Py_EncodeLocale() now use the UTF-8 encoding in the UTF-8 Mode. * Update subprocess._args_from_interpreter_flags() to handle -X utf8 * Skip some tests relying on the current locale if the UTF-8 mode is enabled. * Add test_utf8mode.py. * _Py_DecodeUTF8_surrogateescape() gets a new optional parameter to return also the length (number of wide characters). * pymain_get_global_config() and pymain_set_global_config() now always copy flag values, rather than only copying if the new value is greater than the old value.
* bpo-32030: Add pymain_get_global_config() (#4735)Victor Stinner2017-12-061-4/+6
| | | | | | | | | | | | | * Py_Main() now starts by reading Py_xxx configuration variables to only work on its own private structure, and then later writes back the configuration into these variables. * Replace Py_GETENV() with pymain_get_env_var() which ignores empty variables. * Add _PyCoreConfig.dump_refs * Add _PyCoreConfig.malloc_stats * _PyObject_DebugMallocStats() is now responsible to check if debug hooks are installed. The function returns 1 if stats were written, or 0 if the hooks are disabled. Mark _PyMem_PymallocEnabled() as static.
* bpo-32030: Simplify _PyCoreConfig_INIT macro (#4728)Victor Stinner2017-12-051-18/+4
| | | | | | | * Simplify _PyCoreConfig_INIT, _PyMainInterpreterConfig_INIT, _PyPathConfig_INIT macros: no need to set fields to 0/NULL, it's redundant (the C language sets them to 0/NULL for us). * Fix typo: pymain_run_statup() => pymain_run_startup() * Remove a few XXX/TODO
