* _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
* _PyCoreConfig_Read() no longer directly modifies Py_IsolatedFlag
and Py_NoSiteFlag global configuration flags. The function now
requires two pointers to integer, so these flags can be set later,
to avoid side effets in _PyCoreConfig_Read().
* pathconfig_global_init() now leaves Py_IsolatedFlag and
Py_NoSiteFlag unchanged.
* Fix pathconfig_global_init(): avoid computing the path
configuration twice, use _PyCoreConfig_SetPathConfig().
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.
During development of the limited API support for PySide,
we saw an error in a macro that accessed a type field.
This patch fixes the 7 errors in the Python headers.
Macros which were not written as capitals were implemented
as function.
To do the necessary analysis again, a script was included that
parses all headers and looks for "->tp_" in serctions which can
be reached with active limited API.
It is easily possible to call this script as a test.

* Set the limited API version for PyImport_GetModule and PyOS_*Fork
functions.
* Add PyImport_GetModule and Py_UTF8Mode in PC/python3.def.
* Add several functions in Doc/data/refcounts.dat.
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.
This is not the ideal solution; this means that a test module is now
always included in the main python3x.dll. However, we're already
including xxsubtype, so why not?
bpo-31399: Let OpenSSL verify hostname and IP
The ssl module now uses OpenSSL's X509_VERIFY_PARAM_set1_host() and
X509_VERIFY_PARAM_set1_ip() API to verify hostname and IP addresses.
* Remove match_hostname calls
* Check for libssl with set1_host, libssl must provide X509_VERIFY_PARAM_set1_host()
* Add documentation for OpenSSL 1.0.2 requirement
* Don't support OpenSSL special mode with a leading dot, e.g. ".example.org" matches "www.example.org". It's not standard conform.
* Add hostname_checks_common_name

_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.
Add a new _Py_FindEnvConfigValue() function: code shared between
Windows and Unix implementations of _PyPathConfig_Calculate() to read
the pyenv.cfg file.
_Py_FindEnvConfigValue() now uses _Py_DecodeUTF8_surrogateescape()
instead of using a Python Unicode string, the Python API must not be
used early during Python initialization. Same change in Unix
search_for_exec_prefix(): use _Py_DecodeUTF8_surrogateescape().
Cleanup also encode_current_locale(): PyMem_RawFree/PyMem_Free can be
called with NULL.
Fix also "NUL byte" => "NULL byte" typo.
_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
_PyPathConfig_Init() now also initialize home and program_name:
* Rename existing _PyPathConfig_Init() to _PyPathConfig_Calculate().
Add a new _PyPathConfig_Init() function in pathconfig.c which
handles the _Py_path_config variable and call
_PyPathConfig_Calculate().
* Add home and program_name fields to _PyPathConfig.home
* _PyPathConfig_Init() now initialize home and program_name
from main_config
* Py_SetProgramName(), Py_SetPythonHome() and Py_GetPythonHome() now
calls Py_FatalError() on failure, instead of silently ignoring
failures.
* config_init_home() now gets directly _Py_path_config.home to only
get the value set by Py_SetPythonHome(), or NULL if
Py_SetPythonHome() was not called.
* config_get_program_name() now gets directly
_Py_path_config.program_name to only get the value set by
Py_SetProgramName(), or NULL if Py_SetProgramName() was not called.
* pymain_init_python() doesn't call Py_SetProgramName() anymore,
_PyPathConfig_Init() now always sets the program name
* Call _PyMainInterpreterConfig_Read() in
pymain_parse_cmdline_envvars_impl() to control the memory allocator
* C API documentation: it's no more safe to call Py_GetProgramName()
before Py_Initialize().
* Factorize code from PC/getpathp.c and Modules/getpath.c to remove
duplicated code
* rename pathconfig_clear() to _PyPathConfig_Clear()
* Inline _PyPathConfig_Fini() in pymain_impl() and then remove it,
since it's a oneliner
Changes:
* _PyPathConfig_Fini() cannot be called in Py_FinalizeEx().
Py_Initialize() and Py_Finalize() can be called multiple times, but
it must not "forget" parameters set by Py_SetProgramName(),
Py_SetPath() or Py_SetPythonHome(), whereas _PyPathConfig_Fini()
clear all these parameters.
* config_get_program_name() and calculate_program_full_path() now
also decode paths using Py_DecodeLocale() to use the
surrogateescape error handler, rather than decoding using
mbstowcs() which is strict.
* Change _Py_CheckPython3() prototype: () => (void)
* Truncate a few lines which were too long
* _PyMainInterpreterConfig_ReadEnv() now sets program_name from
environment variables and pymain_parse_envvars() implements the
falls back on argv[0].
* Remove _PyMain.program_name: use the program_name from
_PyMainInterpreterConfig
* Move the Py_SetProgramName() call back to pymain_init_python(),
just before _Py_InitializeCore().
* pathconfig_global_init() now also calls
_PyMainInterpreterConfig_Read() to set program_name if it isn't set
yet
* Cleanup PyCalculatePath: pass main_config to subfunctions to get
directly fields from main_config (home, module_search_path_env and
program_name)
* Rename PyPathConfig structure to _PyPathConfig and move it to
Include/internal/pystate.h
* Rename path_config to _Py_path_config
* _PyPathConfig: Rename program_name field to program_full_path
* Add assert(str != NULL); to _PyMem_RawWcsdup(), _PyMem_RawStrdup()
and _PyMem_Strdup().
* Rename calculate_path() to pathconfig_global_init(). The function
now does nothing if it's already initiallized.
* Py_Main() now calls Py_SetProgramName() earlier to be able to get
the program name in _PyMainInterpreterConfig_ReadEnv().
* Rename prog to program_name
* Rename progpath to program_name
Py_GetPath() and Py_Main() now call
_PyMainInterpreterConfig_ReadEnv() to share the same code to get
environment variables.
Changes:
* Add _PyMainInterpreterConfig_ReadEnv()
* Add _PyMainInterpreterConfig_Clear()
* Add _PyMem_RawWcsdup()
* _PyMainInterpreterConfig: rename pythonhome to home
* Rename _Py_ReadMainInterpreterConfig() to
_PyMainInterpreterConfig_Read()
* Use _Py_INIT_USER_ERR(), instead of _Py_INIT_ERR(), for decoding
errors: the user is able to fix the issue, it's not a bug in
Python. Same change was made in _Py_INIT_NO_MEMORY().
* Remove _Py_GetPythonHomeWithConfig()
Previously, 'msilib.OpenDatabase()' function raised a
cryptical exception message when it couldn't open or
create an MSI file. For example:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
_msi.MSIError: unknown error 6e
* calculate_path() rewritten in Modules/getpath.c and PC/getpathp.c
* Move global variables into a new PyPathConfig structure.
* calculate_path():
* Split the huge calculate_path() function into subfunctions.
* Add PyCalculatePath structure to pass data between subfunctions.
* Document PyCalculatePath fields.
* Move cleanup code into a new calculate_free() subfunction
* calculate_init() now handles Py_DecodeLocale() failures properly
* calculate_path() is now atomic: only replace PyPathConfig
(path_config) at once on success.
* _Py_GetPythonHomeWithConfig() now returns an error on failure
* Add _Py_INIT_NO_MEMORY() helper: report a memory allocation failure
* Coding style fixes (PEP 7)
* Py_Main() now reads the PYTHONHOME environment variable
* Add _Py_GetPythonHomeWithConfig() private function
* Add _PyWarnings_InitWithConfig()
* init_filters() doesn't get the current core configuration from the
current interpreter or Python thread anymore. Pass explicitly the
configuration to _PyWarnings_InitWithConfig().
* _Py_InitializeCore() now fails on _PyWarnings_InitWithConfig()
failure.
* Pass configuration as constant
Changes:
* Py_Main() initializes _PyCoreConfig.module_search_path_env from
the PYTHONPATH environment variable.
* PyInterpreterState_New() now initializes core_config and config
fields
* Compute sys.path a little bit ealier in
_Py_InitializeMainInterpreter() and new_interpreter()
* Add _Py_GetPathWithConfig() private function.
See PEP 539 for details.
Highlights of changes:
- Add Thread Specific Storage (TSS) API
- Document the Thread Local Storage (TLS) API as deprecated
- Update code that used TLS API to use TSS API
