bpo-38644: Pass tstate to _Py_FinishPendingCalls() (GH-17990)
_Py_FinishPendingCalls() now expects a tstate argument, instead of a
runtime argument.

bpo-38858: Small integer per interpreter (GH-17315)
Each Python subinterpreter now has its own "small integer
singletons": numbers in [-5; 257] range.

It is no longer possible to change the number of small integers at
build time by overriding NSMALLNEGINTS and NSMALLPOSINTS macros:
macros should now be modified manually in pycore_pystate.h header
file.

For now, continue to share _PyLong_Zero and _PyLong_One singletons
between all subinterpreters.

bpo-38858: Fix ref leak in pycore_interp_init() (GH-17512)
bpo-38858, bpo-38997: _PySys_Create() returns a strong reference to
the sys module: Py_DECREF() is needed when we are done with the
module.

bpo-38858: new_interpreter() reuses _PySys_Create() (GH-17481)
new_interpreter() now calls _PySys_Create() to create a new sys
module isolated from the main interpreter. It now calls
_PySys_InitCore() and _PyImport_FixupBuiltin().

init_interp_main() now calls _PySys_InitMain().

bpo-38858: new_interpreter() uses pycore_init_import_warnings() (GH-17353) 2019-11-22 21:54:33 +01:00
Victor Stinner 2582d46fbc
bpo-38858: new_interpreter() reuses pycore_init_builtins() (GH-17351)
new_interpreter() now calls _PyBuiltin_Init() to create the builtins
module and calls _PyImport_FixupBuiltin(), rather than using
_PyImport_FindBuiltin(tstate, "builtins").

pycore_init_builtins() is now responsible to initialize
intepr->builtins_copy: inline _PyImport_Init() and remove this
function.

bpo-36854: Clear the current thread later (GH-17279)
Clear the current thread later in the Python finalization.

* The PyInterpreterState_Delete() function is now responsible
  to call PyThreadState_Swap(NULL).
* The tstate_delete_common() function is now responsible to clear the
  "autoTSSKey" thread local storage and it only clears it once the
  thread state is fully cleared. It allows to still get the current
  thread from TSS in tstate_delete_common().

bpo-36710: Add PyInterpreterState.runtime field (GH-17270)
Add PyInterpreterState.runtime field: reference to the _PyRuntime
global variable. This field exists to not have to pass runtime in
addition to tstate to a function.  Get runtime from tstate:
tstate->interp->runtime.

Remove "_PyRuntimeState *runtime" parameter from functions already
taking a "PyThreadState *tstate" parameter.

_PyGC_Init() first parameter becomes "PyThreadState *tstate".

backward compatibility.

* Replace private _config_version field with public struct_size field
  in PyPreConfig and PyConfig.
* Public PyPreConfig_InitIsolatedConfig() and
  PyPreConfig_InitPythonConfig()
  return type becomes PyStatus, instead of void.

  _PyPreConfig_InitFromPreConfig() return type becomes PyStatus,
  instead of void.
* Remove _Py_CONFIG_VERSION
* Update the Initialization Configuration documentation.

bpo-38234: Remove _PyPathConfig.dll_path (GH-16307)
The DLL path is not computed from any user configuration and cannot
be configured by PyConfig. Instead, add a new _Py_dll_path global variable.

Remove _PyConfig_SetPathConfig(): replaced with _PyPathConfig_Init().

Py_Initialize() now longer sets the "global path configuration",
but only initialize _Py_dll_path.

bpo-36829: Add sys.unraisablehook() (GH-13187)
Add new sys.unraisablehook() function which can be overridden to
control how "unraisable exceptions" are handled. It is called when an
exception has occurred but there is no way for Python to handle it.
For example, when a destructor raises an exception or during garbage
collection (gc.collect()).

Changes:

* Add an internal UnraisableHookArgs type used to pass arguments to
  sys.unraisablehook.
* Add _PyErr_WriteUnraisableDefaultHook().
* The default hook now ignores exception on writing the traceback.
* test_sys now uses unittest.main() to automatically discover tests:
  remove test_main().
* Add _PyErr_Init().
* Fix PyErr_WriteUnraisable(): hold a strong reference to sys.stderr

* Fix _Py_LegacyLocaleDetected(): don't attempt to coerce the
  C locale if LC_ALL environment variable is set. Add 'warn'
  parameter: emit_stderr_warning_for_legacy_locale() must not
  the LC_ALL env var.
* _PyPreConfig_Write() sets coerce_c_locale to 0 if
  _Py_CoerceLegacyLocale() fails.
