* bpo-36763: Add _PyCoreConfig_InitPythonConfig() (GH-13388)Victor Stinner2019-05-171-7/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add new functions to get the Python interpreter behavior: * _PyPreConfig_InitPythonConfig() * _PyCoreConfig_InitPythonConfig() Add new functions to get an isolated configuration: * _PyPreConfig_InitIsolatedConfig() * _PyCoreConfig_InitIsolatedConfig() Replace _PyPreConfig_INIT and _PyCoreConfig_INIT with new functions _PyPreConfig_Init() and _PyCoreConfig_Init(). _PyCoreConfig: set configure_c_stdio and parse_argv to 0 by default to behave as Python 3.6 in the default configuration. _PyCoreConfig_Read() no longer sets coerce_c_locale_warn to 1 if it's equal to 0. coerce_c_locale_warn must now be set to -1 (ex: using _PyCoreConfig_InitPythonConfig()) to enable C locale coercion warning. Add unit tests for _PyCoreConfig_InitPythonConfig() and _PyCoreConfig_InitIsolatedConfig(). Changes: * Rename _PyCoreConfig_GetCoreConfig() to _PyPreConfig_GetCoreConfig() * Fix core_read_precmdline(): handle parse_argv=0 * Fix _Py_PreInitializeFromCoreConfig(): pass coreconfig.argv to _Py_PreInitializeFromPyArgv(), except if parse_argv=0
* bpo-36763: Add PyMemAllocatorName (GH-13387)Victor Stinner2019-05-172-7/+18
| | | | | | | | | | | | | | * Add PyMemAllocatorName enum * _PyPreConfig.allocator type becomes PyMemAllocatorName, instead of char* * Remove _PyPreConfig_Clear() * Add _PyMem_GetAllocatorName() * Rename _PyMem_GetAllocatorsName() to _PyMem_GetCurrentAllocatorName() * Remove _PyPreConfig_SetAllocator(): just call _PyMem_SetupAllocators() directly, we don't have do reallocate the configuration with the new allocator anymore! * _PyPreConfig_Write() parameter becomes const, as it should be in the first place!
* bpo-36763: Remove _PyCoreConfig.program (GH-13373)Victor Stinner2019-05-171-5/+9
| | | Use _PyCoreConfig.program_name instead.
* bpo-36763: Add _PyCoreConfig.configure_c_stdio (GH-13363)Victor Stinner2019-05-161-0/+9
| | | Add tests for configure_c_stdio and pathconfig_warnings parameters.
* bpo-36763: Add _Py_InitializeMain() (GH-13362)Victor Stinner2019-05-162-4/+10
| | | | | | | | | * Add a private _Py_InitializeMain() function. * Add again _PyCoreConfig._init_main. * _Py_InitializeFromConfig() now uses _init_main to decide if _Py_InitializeMainInterpreter() should be called. * _PyCoreConfig: rename _frozen to pathconfig_warnings, its value is now the opposite of Py_FrozenFlag. * Add an unit test for _init_main=0 and _Py_InitializeMain().
* bpo-36763: Add _PyCoreConfig.parse_argv (GH-13361)Victor Stinner2019-05-161-22/+39
| | | | | | | * _PyCoreConfig_Read() doesn't parse nor update argv if parse_argv is 0. * Move path configuration fields in _PyCoreConfig. * Add an unit test for parse_argv=0. * Remove unused "done": label in _Py_RunMain().
* bpo-36763: _PyInitError always use int for exitcode (GH-13360)Victor Stinner2019-05-161-4/+0
| | | | | | | | | | | | | | | | | We cannot use "unsigned int" for exitcode on Windows, since Py_Main() and _Py_RunMain() always return an "int". Changes: * _PyPathConfig_ComputeSysPath0() now returns -1 if an exception is raised. * pymain_run_python() no longer uses _PyInitError but display the exception and set exitcode to 1 in case of error. * Fix _Py_RunMain(): return an exitcode rather than calling exit() on pymain_run_python() failure. * _Py_ExitInitError() no longer uses ExitProcess() on Windows, use exit() on all platforms. * _Py_ExitInitError() now fails with a fatal error if 'err' is not an error not an exit.
* bpo-36763: Remove _PyCoreConfig._init_main (GH-13066)Victor Stinner2019-05-021-5/+1

* bpo-36763: Make _PyCoreConfig.check_hash_pycs_mode public (GH-13052)Victor Stinner2019-05-021-4/+3
| | | | | _PyCoreConfig: Rename _check_hash_pycs_mode field to check_hash_pycs_mode (make it public) and change its type from "const char*" to "wchar_t*".
* bpo-36763: Rework _PyInitError API (GH-13031)Victor Stinner2019-05-011-15/+28
| | | | | | | | | * Remove _PyInitError.user_err field and _Py_INIT_USER_ERR() macro: use _Py_INIT_ERR() instead. _Py_ExitInitError() now longer calls abort() on error: exit with exit code 1 instead. * Add _PyInitError._type private field. * exitcode field type is now unsigned int on Windows. * Rename prefix field to _func. * Rename msg field to err_msg.

| | | | | | Add a new _testinternalcapi module to test the internal C API. Move _Py_GetConfigsAsDict() function to the internal C API: _testembed now uses _testinternalcapi to access the function.
* bpo-35134: Add Include/cpython/pymem.h (GH-12840)Victor Stinner2019-04-151-0/+99
| | | | Move unstable CPython API from Include/pymem.h into a new Include/cpython/pymem.h header file.
* bpo-36389: Add _PyObject_CheckConsistency() function (GH-12803)Victor Stinner2019-04-121-0/+15
| | | | | | Add a new _PyObject_CheckConsistency() function which can be used to help debugging. The function is available in release mode. Add a 'check_content' parameter to _PyDict_CheckConsistency().

| | | | | * Add config_read_cmdline() subfunction. Remove _PyCmdline structure. * _PyCoreConfig_Read() now also parses config->argv command line arguments
* bpo-36443: Disable C locale coercion and UTF-8 Mode by default (GH-12589)Victor Stinner2019-03-271-7/+20
| | | | | | | | | | | | | | | | | | | | | | | | bpo-36443, bpo-36202: Since Python 3.7.0, calling Py_DecodeLocale() before Py_Initialize() produces mojibake if the LC_CTYPE locale is coerced and/or if the UTF-8 Mode is enabled by the user configuration. This change fix the issue by disabling LC_CTYPE coercion and UTF-8 Mode by default. They must now be enabled explicitly (opt-in) using the new _Py_PreInitialize() API with _PyPreConfig. When embedding Python, set coerce_c_locale and utf8_mode attributes of _PyPreConfig to -1 to enable automatically these parameters depending on the LC_CTYPE locale, environment variables and command line arguments Alternative: Setting Py_UTF8Mode to 1 always explicitly enables the UTF-8 Mode. Changes: * _PyPreConfig_INIT now sets coerce_c_locale and utf8_mode to 0 by default. * _Py_InitializeFromArgs() and _Py_InitializeFromWideArgs() can now be called with config=NULL.
* bpo-36444: Rework _Py_InitializeFromConfig() API (GH-12576)Victor Stinner2019-03-272-19/+19

* bpo-36301: Add _Py_PreInitializeFromConfig() (GH-12536)Victor Stinner2019-03-252-1/+5
| | | | | | | * Initialize _PyPreConfig.dev_mode to -1. * _PyPreConfig_Read(): coreconfig has the priority over preconfig. * _PyCoreConfig_Read() now calls _PyPreCmdline_Read() internally. * config_from_cmdline() now pass _PyPreCmdline to config_read(). * Add _PyPreCmdline_Copy().
* bpo-36301: Cleanup preconfig code (GH-12535)Victor Stinner2019-03-251-1/+6
| | | | | | | | | | | | | | | Prepare code to move some _PyPreConfig parameters into _PyPreCmdline. Changes: * _PyCoreConfig_ReadFromArgv(): remove preconfig parameter, use _PyRuntime.preconfig. * Add _PyPreCmdline_GetPreConfig() (called by _PyPreConfig_Read()). * Rename _PyPreCmdline_Init() to _PyPreCmdline_SetArgv() * Factorize _Py_PreInitializeFromPreConfig() code: add pyinit_preinit(). * _PyPreConfig_Read() now sets coerce_c_locale to 2 if it must be coerced. * Remove _PyCoreConfig_ReadPreConfig(). * _PyCoreConfig_Write() now copies updated preconfig into _PyRuntime.

| | | | | | | | | * Add _PyRuntime.pre_initialized: set to 1 when Python is pre-initialized * Add _Py_PreInitialize() and _Py_PreInitializeFromPreConfig(). * _PyCoreConfig_Read() now calls _Py_PreInitialize(). * Move _PyPreConfig_GetGlobalConfig() and _PyCoreConfig_GetGlobalConfig() calls from main.c to preconfig.c and coreconfig.c.
* bpo-36356: Release Unicode interned strings on Valgrind (#12431)Victor Stinner2019-03-191-2/+0
| | | | | | | | | | | When Python is compiled with Valgrind support, release Unicode interned strings at exit in _PyUnicode_Fini(). * Rename _Py_ReleaseInternedUnicodeStrings() to unicode_release_interned() and make it private. * unicode_release_interned() is now called from _PyUnicode_Fini(): it must be called with a running Python thread state for TRASHCAN, it cannot be called from pymain_free(). * Don't display statistics on interned strings at exit anymore
* Fix typo in _PyObject_FastCallDict documentation (GH-12383)Rémi Lapeyre2019-03-181-1/+1
