* bpo-39028: Performance enhancement in keyword extraction (GH-17576)Sebastian Berg2019-12-181-3/+7
| | | | | | | | All keywords should first be checked for pointer identity. Only after that failed for all keywords (unlikely) should unicode equality be used. The original code would call unicode equality on any non-matching keyword argument. Meaning calling it often e.g. when a function has many kwargs but only the last one is provided.
* bpo-39080: Starred Expression's column offset fix when inside a CALL (GH-17645)Lysandros Nikolaou2019-12-181-1/+1

* bpo-38858: Small integer per interpreter (GH-17315)Victor Stinner2019-12-171-4/+9
| | | | | | | | | | | | 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-39031: Include elif keyword when producing lineno/col-offset info for ↵Lysandros Nikolaou2019-12-121-2/+2
| | | | | | | | | | | | if_stmt (GH-17582) When parsing an "elif" node, lineno and col_offset of the node now point to the "elif" keyword and not to its condition, making it consistent with the "if" node. https://bugs.python.org/issue39031 Automerge-Triggered-By: @pablogsal

* bpo-20443: No longer make sys.argv[0] absolute for script (GH-17534)Victor Stinner2019-12-091-4/+0
| | | | | In Python 3.9.0a1, sys.argv[0] was made an asolute path if a filename was specified on the command line. Revert this change, since most users expect sys.argv to be unmodified.
* bpo-38858: Fix ref leak in pycore_interp_init() (GH-17512)Victor Stinner2019-12-081-5/+10
| | | | | 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-38979: fix ContextVar "__class_getitem__" method (GH-17497)AMIR2019-12-081-3/+4
| | | | | | | | | | now contextvars.ContextVar "__class_getitem__" method returns ContextVar class, not None. https://bugs.python.org/issue38979 Automerge-Triggered-By: @asvetlov

* bpo-38858: Add pycore_interp_init() code to factorize code (GH-17483)Victor Stinner2019-12-061-32/+24
| | | | Add a new pycore_interp_init() function called by new_interpreter() and pyinit_config().
* bpo-38858: new_interpreter() reuses _PySys_Create() (GH-17481)Victor Stinner2019-12-062-54/+46
| | | | | | | 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)Victor Stinner2019-11-222-40/+24
| | | | | | | | | 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)Victor Stinner2019-11-222-45/+64
| | | | | 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: Add init_interp_main() subfunction (GH-17347)Victor Stinner2019-11-221-103/+109
| | | | Fix new_interpreter() error handling: undo it all if status is an exception.

* bpo-36854: Fix refleak in subinterpreter (GH-17331)Victor Stinner2019-11-221-0/+8
| | | | finalize_interp_clear() now explicitly clears the codec registry and then trigger a GC collection to clear all references.
* Produce cleaner bytecode for 'with' and 'async with' by generating separate ↵Mark Shannon2019-11-217-4449/+4322
| | | | | | code for normal and exceptional paths. (#6641) Remove BEGIN_FINALLY, END_FINALLY, CALL_FINALLY and POP_FINALLY bytecodes. Implement finally blocks by code duplication. Reimplement frame.lineno setter using line numbers rather than bytecode offsets.
* bpo-38858: Fix Py_Finalize() when called from a subinterpreter (GH-17297)Victor Stinner2019-11-201-11/+18
| | | | Use _Py_IsMainInterpreter() in Py_Initialize() and Py_Finalize() to detect if the current interpreter is the main interpreter or not.
* bpo-38858: Add _Py_IsMainInterpreter(tstate) (GH-17293)Victor Stinner2019-11-201-0/+6

* bpo-37340: Remove PyMethod_ClearFreeList() and PyCFunction_ClearFreeList() ↵Victor Stinner2019-11-201-2/+0
| | | | | | | | (GH-17284) 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)Victor Stinner2019-11-202-2/+3
| | | | | * Rename _PyGC_InitializeRuntime() to _PyGC_InitState() * finalize_interp_clear() now also calls _PyGC_Fini() in subinterpreters (clear the GC state).
* bpo-38858: Fix reference leak in pycore_init_types() (GH-17286)Victor Stinner2019-11-201-20/+26
| | | | Only call _PyGC_Init(), _PyExc_Init() and _PyErr_Init() in new_interpreter().
* bpo-36854: gcmodule.c gets its state from tstate (GH-17285)Victor Stinner2019-11-201-1/+1
| | | | | | | | | * 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-36854: Clear the current thread later (GH-17279)Victor Stinner2019-11-202-27/+35
| | | | | | | | | | 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-38858: Factorize Py_EndInterpreter() code (GH-17273)Victor Stinner2019-11-202-54/+78
| | | | | | * 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-38835: Don't use PyFPE_START_PROTECT and PyFPE_END_PROTECT (GH-17231)Victor Stinner2019-11-202-6/+0
| | | | | The PyFPE_START_PROTECT() and PyFPE_END_PROTECT() macros are empty: they have been doing nothing for the last year (since commit 735ae8d139a673b30b321dc10acfd3d14f0d633b), so stop using them.
* bpo-36710: Add PyInterpreterState.runtime field (GH-17270)Victor Stinner2019-11-204-82/+70
| | | | | | | | | | | 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".

| | | | | * Rename _PyGC_Initialize() to _PyGC_InitializeRuntime() * Add _PyGC_Init(): initialize _PyRuntime.gc.garbage list * Call _PyGC_Init() before _PyTypes_Init()
* bpo-38858: Reorganize pycore_init_types() (GH-17265)Victor Stinner2019-11-201-20/+11
| | | | * Call _PyLong_Init() and _PyExc_Init() earlier * new_interpreter() reuses pycore_init_types()
* bpo-38644: Add _PyEval_EvalCode() (GH-17183)Victor Stinner2019-11-161-4/+24
| | | _PyFunction_Vectorcall() now pass tstate to function calls.
* bpo-38644: Add _PyObject_Call() (GH-17089)Victor Stinner2019-11-143-15/+19
| | | | | | | | | | * Add pycore_call.h internal header file. * Add _PyObject_Call(): PyObject_Call() with tstate * Add _PyObject_CallNoArgTstate(): _PyObject_CallNoArg() with tstate * Add _PyObject_FastCallDictTstate(): _PyObject_FastCallDict() with tstate * _PyObject_Call_Prepend() now takes tstate * Replace _PyObject_FastCall() calls with _PyObject_VectorcallTstate() calls
* bpo-38644: Add _PyEval_EvalFrame() with tstate (GH-17131)Victor Stinner2019-11-141-5/+7
| | | | Add _PyEval_EvalFrame() static inline function to get eval_frame from tstate->interp.
* bpo-38644: Add _PyObject_VectorcallTstate() (GH-17052)Victor Stinner2019-11-081-17/+31
| | | | | * Add _PyObject_VectorcallTstate() function: similar to _PyObject_Vectorcall(), but with tstate parameter * Add tstate parameter to _PyObject_MakeTpCall()
* bpo-38733: PyErr_Occurred() caller must hold the GIL (GH-17080)Victor Stinner2019-11-071-0/+3
| | | | | | | | | | | bpo-3605, bpo-38733: Optimize _PyErr_Occurred(): remove "tstate == NULL" test. Py_FatalError() no longer calls PyErr_Occurred() if called without holding the GIL. So PyErr_Occurred() no longer has to support tstate==NULL case. _Py_CheckFunctionResult(): use directly _PyErr_Occurred() to avoid explicit "!= NULL" test.
* bpo-37645: add new function _PyObject_FunctionStr() (GH-14890)Jeroen Demeyer2019-11-051-19/+30
| | | | | | | | | | | | Additional note: the `method_check_args` function in `Objects/descrobject.c` is written in such a way that it applies to all kinds of descriptors. In particular, a future re-implementation of `wrapper_descriptor` could use that code. CC @vstinner @encukou https://bugs.python.org/issue37645 Automerge-Triggered-By: @encukou

* bpo-38644: Pass tstate to _Py_CheckFunctionResult() (GH-17050)Victor Stinner2019-11-052-1/+16
| | | | | * Add tstate parameter to _Py_CheckFunctionResult() * Add _PyErr_FormatFromCauseTstate() * Replace PyErr_XXX(...) with _PyErr_XXX(state, ...)
* bpo-38644: Pass tstate to Py_EnterRecursiveCall() (GH-16997)Victor Stinner2019-11-051-7/+7
| | | | | | | | | | | | | * Add _Py_EnterRecursiveCall() and _Py_LeaveRecursiveCall() which require a tstate argument. * Pass tstate to _Py_MakeRecCheck() and _Py_CheckRecursiveCall(). * Convert Py_EnterRecursiveCall() and Py_LeaveRecursiveCall() macros to static inline functions. _PyThreadState_GET() is the most efficient way to get the tstate, and so using it with _Py_EnterRecursiveCall() and _Py_LeaveRecursiveCall() should be a little bit more efficient than using Py_EnterRecursiveCall() and Py_LeaveRecursiveCall() which use the "slower" PyThreadState_GET().
