bpo-38858: new_interpreter() reuses _PySys_Create() (GH-17481)

2019-12-06T01:43:30+00:00

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() reuses pycore_init_builtins() (GH-17351)

2019-11-22T18:24:49+00:00

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-38858: _PyImport_FixupExtensionObject() handles subinterpreters (GH-17350)

2019-11-22T17:52:27+00:00

If _PyImport_FixupExtensionObject() is called from a subinterpreter,
leave extensions unchanged and don't copy the module dictionary
into def->m_base.m_copy.

bpo-38858: Call _PyUnicode_Fini() in Py_EndInterpreter() (GH-17330)

2019-11-22T11:27:50+00:00

Py_EndInterpreter() now clears the filesystem codec.

bpo-38858: Add _Py_IsMainInterpreter(tstate) (GH-17293)

2019-11-20T16:34:39+00:00

bpo-37340: Remove PyMethod_ClearFreeList() and PyCFunction_ClearFreeList() (GH-17284)

2019-11-20T11:59:12+00:00

Remove PyMethod_ClearFreeList() and PyCFunction_ClearFreeList()
functions: the free lists of bound method objects have been removed.

Remove also _PyMethod_Fini() and _PyCFunction_Fini() functions.

bpo-36854: Move _PyRuntimeState.gc to PyInterpreterState (GH-17287)

2019-11-20T11:25:50+00:00

* Rename _PyGC_InitializeRuntime() to _PyGC_InitState()
* finalize_interp_clear() now also calls _PyGC_Fini() in
  subinterpreters (clear the GC state).

bpo-36854: gcmodule.c gets its state from tstate (GH-17285)

2019-11-20T10:48:18+00:00

* Add GCState type for readability
* gcmodule.c now gets its gcstate from tstate
* _PyGC_DumpShutdownStats() now expects tstate rather than runtime
* Rename "state" to "gcstate" for readability: to avoid confusion
  between "state" and "tstate" for example.
* collect() now only expects tstate: it gets gcstate from tstate.
* Pass tstate to _PyErr_xxx() functions

bpo-38858: Factorize Py_EndInterpreter() code (GH-17273)

2019-11-20T09:38:34+00:00

* Factorize code in common between Py_FinalizeEx() and
  Py_EndInterpreter().
* Py_EndInterpreter() now also calls _PyWarnings_Fini().
* Call _PyExc_Fini() and _PyGC_Fini() later in the finalization.

bpo-36710: Add PyInterpreterState.runtime field (GH-17270)

2019-11-20T01:27:56+00:00

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".
