Py_Initialize() and Py_Main() cannot enable the C locale coercion
(PEP 538) anymore: it is always disabled. It can now only be enabled
by the Python program ("python3).
test_embed: get_filesystem_encoding() doesn't have to set PYTHONUTF8
nor PYTHONCOERCECLOCALE, these variables are already set in the
parent.
_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 "_").
* Py_FileSystemDefaultEncoding and Py_FileSystemDefaultEncodeErrors
default value is now NULL: initfsencoding() set them
during Python initialization.
* Document how Python chooses the filesystem encoding and error
handler.
* Add an assertion to _PyCoreConfig_Read().
_PyCoreConfig_Read() is now responsible to choose the filesystem
encoding and error handler. Using Py_Main(), the encoding is now
chosen even before calling Py_Initialize().
_PyCoreConfig.filesystem_encoding is now the reference, instead of
Py_FileSystemDefaultEncoding, for the Python filesystem encoding.
Changes:
* Add filesystem_encoding and filesystem_errors to _PyCoreConfig
* _PyCoreConfig_Read() now reads the locale encoding for the file
system encoding.
* PyUnicode_EncodeFSDefault() and PyUnicode_DecodeFSDefaultAndSize()
now use the interpreter configuration rather than
Py_FileSystemDefaultEncoding and Py_FileSystemDefaultEncodeErrors
global configuration variables.
* Add _Py_SetFileSystemEncoding() and _Py_ClearFileSystemEncoding()
private functions to only modify Py_FileSystemDefaultEncoding and
Py_FileSystemDefaultEncodeErrors in coreconfig.c.
* _Py_CoerceLegacyLocale() now takes an int rather than
_PyCoreConfig for the warning.
* _Py_InitializeCore() now sets the LC_CTYPE locale to the user
preferred locale before checking if the C locale should be coerced
or not in _PyCoreConfig_Read().
* Fix pymain_read_conf(): remember if the C locale has been coerced
when the configuration should be read again if the encoding has
changed.
On HP-UX with C or POSIX locale, sys.getfilesystemencoding() now returns
"ascii" instead of "roman8" (when the UTF-8 Mode is disabled and the C locale
is not coerced).
nl_langinfo(CODESET) announces "roman8" whereas it uses the Latin1
encoding in practice.
* The UTF-8 Mode is now also enabled by the "POSIX" locale, not only
by the "C" locale.
* On FreeBSD, Py_DecodeLocale() and Py_EncodeLocale() now also forces
the ASCII encoding if the LC_CTYPE locale is "POSIX", not only if
the LC_CTYPE locale is "C".
* test_utf8_mode.test_cmd_line() checks also that the command line
arguments are decoded from UTF-8 when the the UTF-8 Mode is enabled
with POSIX locale or C locale.
bpo-34492: Python/coreconfig.c: Add missing NULL check to _Py_wstrlist_copy().
Fix _Py_wstrlist_clear() call on a wrong list.
Reported by Svace static analyzer.
bpo-31650, bpo-34170: Replace _Py_CheckHashBasedPycsMode with
_PyCoreConfig._check_hash_pycs_mode. Modify PyInit__imp() and
zipimport to get the parameter from the current interpreter core
configuration.
Remove Include/internal/import.h file.
* 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
