* bpo-40421: Add PyFrame_GetBack() function (GH-19765)Victor Stinner2020-04-293-15/+32
| | | | | | New PyFrame_GetBack() function: get the frame next outer frame. Replace frame->f_back with PyFrame_GetBack(frame) in most code but frameobject.c, ceval.c and genobject.c.
* bpo-40429: PyThreadState_GetFrame() returns a strong ref (GH-19781)Victor Stinner2020-04-292-4/+6
| | | | The PyThreadState_GetFrame() function now returns a strong reference to the frame.
* bpo-40428: Remove PyTuple_ClearFreeList() function (GH-19769)Victor Stinner2020-04-291-8/+5
| | | | | | | | | | | | | | | | | | | Remove the following function from the C API: * PyAsyncGen_ClearFreeLists() * PyContext_ClearFreeList() * PyDict_ClearFreeList() * PyFloat_ClearFreeList() * PyFrame_ClearFreeList() * PyList_ClearFreeList() * PySet_ClearFreeList() * PyTuple_ClearFreeList() Make these functions private, move them to the internal C API and change their return type to void. Call explicitly PyGC_Collect() to free all free lists. Note: PySet_ClearFreeList() did nothing.
* bpo-40429: PyFrame_GetCode() now returns a strong reference (GH-19773)Victor Stinner2020-04-283-8/+12
|
* bpo-40429: PyFrame_GetCode() result cannot be NULL (GH-19772)Victor Stinner2020-04-282-10/+8
| | | Add frame_nslots() to factorize duplicate code.
* bpo-40421: Add PyFrame_GetCode() function (GH-19757)Victor Stinner2020-04-283-16/+22
| | | | | | | | | PyFrame_GetCode(frame): return a borrowed reference to the frame code. Replace frame->f_code with PyFrame_GetCode(frame) in most code, except in frameobject.c, genobject.c and ceval.c. Also add PyFrame_GetLineNumber() to the limited C API.
* bpo-40334: Support CO_FUTURE_BARRY_AS_BDFL in the new parser (GH-19721)Pablo Galindo2020-04-271-2/+2
| | | This commit also allows to pass flags to the new parser in all interfaces and fixes a bug in the parser generator that was causing to inline rules with actions, making them disappear.
* bpo-40048: Fix _PyCode_InitOpcache() error path (GH-19691)Victor Stinner2020-04-241-1/+1
| | | | | | If _PyCode_InitOpcache() fails in _PyEval_EvalFrameDefault(), use "goto exit_eval_frame;" rather than "return NULL;" to exit the function in a consistent state. For example, tstate->frame is now reset properly.
* bpo-40334: Use old compiler when compile mode is func_type (GH-19692)Guido van Rossum2020-04-231-1/+1
| | | | | This is invoked by mypy, using ast.parse(source, "<func_type>", "func_type"). Since the new grammar doesn't yet support the func_type_input start symbol we must use the old compiler in this case to prevent a crash. https://bugs.python.org/issue40334
* bpo-40334: Improve various PEG-Parser related stuff (GH-19669)Lysandros Nikolaou2020-04-231-1/+1
| | | The changes in this commit are all related to @vstinner's original review comments of the initial PEP 617 implementation PR.
* bpo-40334: Don't downcast from Py_ssize_t to int (GH-19671)Pablo Galindo2020-04-231-1/+1
|
* bpo-40334: Rename PyConfig.use_peg to _use_peg_parser (GH-19670)Victor Stinner2020-04-234-16/+14
| | | | | | | | | | | * Rename PyConfig.use_peg to _use_peg_parser * Document PyConfig._use_peg_parser and mark it a deprecated * Mark -X oldparser option and PYTHONOLDPARSER env var as deprecated in the documentation. * Add use_old_parser() and skip_if_new_parser() to test.support * Remove sys.flags.use_peg: use_old_parser() uses _testinternalcapi.get_configs() instead. * Enhance test_embed tests * subprocess._args_from_interpreter_flags() copies -X oldparser
* bpo-40334: PEP 617 implementation: New PEG parser for CPython (GH-19503)Pablo Galindo2020-04-228-57/+182

* bpo-39562: Prevent collision of future and compiler flags (GH-19230)Batuhan Taşkaya2020-04-221-1/+1
| | | | | | The constant values of future flags in the __future__ module is updated in order to prevent collision with compiler flags. Previously PyCF_ALLOW_TOP_LEVEL_AWAIT was clashing with CO_FUTURE_DIVISION.
* bpo-40313: speed up bytes.hex() (GH-19594)sweeneyde2020-04-211-12/+49

|
* bpo-40302: Replace PY_INT64_T with int64_t (GH-19573)Victor Stinner2020-04-171-3/+3
| | | | | | | | | * Replace PY_INT64_T with int64_t * Replace PY_UINT32_T with uint32_t * Replace PY_UINT64_T with uint64_t sha3module.c no longer checks if PY_UINT64_T is defined since it's always defined and uint64_t is always available on platforms supported by Python.
* Optimize _Py_strhex_impl() (GH-19535)Victor Stinner2020-04-151-24/+26
| | | | | | | Avoid a temporary buffer to create a bytes string: use PyBytes_FromStringAndSize() to directly allocate a bytes object. Cleanup also the code: PEP 7 formatting, move variable definitions closer to where they are used. Fix assertion checking "j" index.
* bpo-40268: Remove unused imports in pylifecycle.c (GH-19533)Victor Stinner2020-04-154-61/+50
| | | | | | | | | | Remove unused imports in files: * initconfig.c * main.c * preconfig.h * pylifecycle.c * python.c * pythonrun.c

|
* bpo-40268: Remove unused structmember.h includes (GH-19530)Victor Stinner2020-04-157-9/+7
| | | | | | If only offsetof() is needed: include stddef.h instead. When structmember.h is used, add a comment explaining that PyMemberDef is used.
* bpo-40268: Remove explicit pythread.h includes (#19529)Victor Stinner2020-04-155-8/+0
| | | | Remove explicit pythread.h includes: it is always included by Python.h.

* bpo-40232: Update PyOS_AfterFork_Child() to use _PyThread_at_fork_reinit() ↵Dong-hee Na2020-04-143-10/+14
| | | | (GH-19450)
* bpo-40268: Remove a few pycore_pystate.h includes (GH-19510)Victor Stinner2020-04-1419-31/+32
|
* bpo-40268: Rename _PyInterpreterState_GET_UNSAFE() (GH-19509)Victor Stinner2020-04-1412-24/+24
| | | | | | | Rename _PyInterpreterState_GET_UNSAFE() to _PyInterpreterState_GET() for consistency with _PyThreadState_GET() and to have a shorter name (help to fit into 80 columns). Add also "assert(tstate != NULL);" to the function.
* bpo-40268: Include explicitly pycore_interp.h (GH-19505)Victor Stinner2020-04-149-4/+14
| | | | pycore_pystate.h no longer includes pycore_interp.h: it's now included explicitly in files accessing PyInterpreterState.

* bpo-40268: Add pycore_runtime.h header file (GH-19493)Victor Stinner2020-04-132-4/+3
| | | | | | Move PyRuntimeState from pycore_pystate.h to pycore_runtime.h. Remove _PyGILState_check_enabled macro: access directly _PyRuntime.gilstate.check_enabled.
* bpo-40268: Add _PyInterpreterState_GetConfig() (GH-19492)Victor Stinner2020-04-139-38/+58
| | | | | | | | Don't access PyInterpreterState.config member directly anymore, but use new functions: * _PyInterpreterState_GetConfig() * _PyInterpreterState_SetConfig() * _Py_GetConfig()
* bpo-40246: Report a better error message for invalid string prefixes (GH-19476)Lysandros Nikolaou2020-04-121-0/+3

* bpo-40082: trip_signal() uses the main interpreter (GH-19441)Victor Stinner2020-04-082-64/+69
| | | | | | | | | | | | | | | | | | | | | | Fix the signal handler: it now always uses the main interpreter, rather than trying to get the current Python thread state. The following function now accepts an interpreter, instead of a Python thread state: * _PyEval_SignalReceived() * _Py_ThreadCanHandleSignals() * _PyEval_AddPendingCall() * COMPUTE_EVAL_BREAKER() * SET_GIL_DROP_REQUEST(), RESET_GIL_DROP_REQUEST() * SIGNAL_PENDING_CALLS(), UNSIGNAL_PENDING_CALLS() * SIGNAL_PENDING_SIGNALS(), UNSIGNAL_PENDING_SIGNALS() * SIGNAL_ASYNC_EXC(), UNSIGNAL_ASYNC_EXC() Py_AddPendingCall() now uses the main interpreter if it fails to the current Python thread state. Convert _PyThreadState_GET() and PyInterpreterState_GET_UNSAFE() macros to static inline functions.

* bpo-40226: PyInterpreterState_Delete() deletes pending calls (GH-19436)Victor Stinner2020-04-083-49/+105
| | | | | | | | | | | | | | | PyInterpreterState_New() is now responsible to create pending calls, PyInterpreterState_Delete() now deletes pending calls. * Rename _PyEval_InitThreads() to _PyEval_InitGIL() and rename _PyEval_InitGIL() to _PyEval_FiniGIL(). * _PyEval_InitState() and PyEval_FiniState() now create and delete pending calls. _PyEval_InitState() now returns -1 on memory allocation failure. * Add init_interp_create_gil() helper function: code shared by Py_NewInterpreter() and Py_InitializeFromConfig(). * init_interp_create_gil() now also calls _PyEval_FiniGIL(), _PyEval_InitGIL() and _PyGILState_Init() in subinterpreters, but these functions now do nothing when called from a subinterpreter.
* bpo-40170: Add _PyIndex_Check() internal function (GH-19426)Victor Stinner2020-04-082-3/+5
| | | | | | | | | Add _PyIndex_Check() function to the internal C API: fast inlined verson of PyIndex_Check(). Add Include/internal/pycore_abstract.h header file. Replace PyIndex_Check() with _PyIndex_Check() in C files of Objects and Python subdirectories.
* bpo-40089: Add _at_fork_reinit() method to locks (GH-19195)Victor Stinner2020-04-071-0/+20
| | | | | | | | | | | | | | | Add a private _at_fork_reinit() method to _thread.Lock, _thread.RLock, threading.RLock and threading.Condition classes: reinitialize the lock after fork in the child process; reset the lock to the unlocked state. Rename also the private _reset_internal_locks() method of threading.Event to _at_fork_reinit(). * Add _PyThread_at_fork_reinit() private function. It is excluded from the limited C API. * threading.Thread._reset_internal_locks() now calls _at_fork_reinit() on self._tstate_lock rather than creating a new Python lock object.
* bpo-40147: Fix a compiler warning on Windows in Python/compile.c (GH-19389)Zackery Spytz2020-04-061-4/+5
| | | Change the type of nkeywords to Py_ssize_t.
