bpo-43510: Implement PEP 597 opt-in EncodingWarning. (GH-19481)

2021-03-29T03:28:14+00:00

See [PEP 597](https://www.python.org/dev/peps/pep-0597/).

* Add `-X warn_default_encoding` and `PYTHONWARNDEFAULTENCODING`.
* Add EncodingWarning
* Add io.text_encoding()
* open(), TextIOWrapper() emits EncodingWarning when encoding is omitted and warn_default_encoding is enabled.
* _pyio.TextIOWrapper() uses UTF-8 as fallback default encoding used when failed to import locale module. (used during building Python)
* bz2, configparser, gzip, lzma, pathlib, tempfile modules use io.text_encoding().
* What's new entry

bpo-43268: Pass interp rather than tstate to internal functions (GH-24580)

2021-02-19T14:10:45+00:00

Pass the current interpreter (interp) rather than the current Python
thread state (tstate) to internal functions which only use the
interpreter.

Modified functions:

* _PyXXX_Fini() and _PyXXX_ClearFreeList() functions
* _PyEval_SignalAsyncExc(), make_pending_calls()
* _PySys_GetObject(), sys_set_object(), sys_set_object_id(), sys_set_object_str()
* should_audit(), set_flags_from_config(), make_flags()
* _PyAtExit_Call()
* init_stdio_encoding()
* etc.

bpo-42521: Add note about 'Python -d' only working on debug builds (GH-23607)

bpo-42260: Improve error handling in _PyConfig_FromDict (GH-23488)

2020-11-24T12:07:32+00:00

bpo-42260: Fix _PyConfig_Read() if compute_path_config=0 (GH-23220)

2020-11-10T20:10:22+00:00

Fix _PyConfig_Read() if compute_path_config=0: use values set by
Py_SetPath(), Py_SetPythonHome() and Py_SetProgramName(). Add
compute_path_config parameter to _PyConfig_InitPathConfig().

The following functions now return NULL if called before
Py_Initialize():

* Py_GetExecPrefix()
* Py_GetPath()
* Py_GetPrefix()
* Py_GetProgramFullPath()
* Py_GetProgramName()
* Py_GetPythonHome()

These functions no longer automatically computes the Python Path
Configuration. Moreover, Py_SetPath() no longer computes
program_full_path.

bpo-42260: Compute the path config in the main init (GH-23211)

2020-11-10T12:21:52+00:00

The path configuration is now computed in the "main" initialization.
The core initialization no longer computes it.

* Add _PyConfig_Read() function to read the configuration without
  computing the path configuration.
* pyinit_core() no longer computes the path configuration: it is now
  computed by init_interp_main().
* The path configuration output members of PyConfig are now optional:

  * executable
  * base_executable
  * prefix
  * base_prefix
  * exec_prefix
  * base_exec_prefix

* _PySys_UpdateConfig() now skips NULL strings in PyConfig.
* _testembed: Rename test_set_config() to test_init_set_config() for
  consistency with other tests.

bpo-42260: PyConfig_Read() only parses argv once (GH-23168)

2020-11-05T17:58:07+00:00

The PyConfig_Read() function now only parses PyConfig.argv arguments
once: PyConfig.parse_argv is set to 2 after arguments are parsed.
Since Python arguments are strippped from PyConfig.argv, parsing
arguments twice would parse the application options as Python
options.

* Rework the PyConfig documentation.
* Fix _testinternalcapi.set_config() error handling.
* SetConfigTests no longer needs parse_argv=0 when restoring the old
  configuration.

bpo-42260: Add _PyConfig_FromDict() (GH-23167)

2020-11-05T17:12:33+00:00

* Rename config_as_dict() to _PyConfig_AsDict().
* Add 'module_search_paths_set' to _PyConfig_AsDict().
* Add _PyConfig_FromDict().
* Add get_config() and set_config() to _testinternalcapi.
* Add config_check_consistency().

bpo-42260: Add _PyInterpreterState_SetConfig() (GH-23158)

2020-11-04T23:45:56+00:00

* Inline _PyInterpreterState_SetConfig(): replace it with
  _PyConfig_Copy().
* Add _PyErr_SetFromPyStatus()
* Add _PyInterpreterState_GetConfigCopy()
* Add a new _PyInterpreterState_SetConfig() function.
* Add an unit which gets, modifies, and sets the config.
