* [3.9] bpo-43710: Rollback the 3.9 bpo-42500 fix, it broke the ABI in 3.9.3 ↵Gregory P. Smith2021-04-041-0/+16
| | | | | | | (#25179) This reverts commit 8b795ab5541d8a4e69be4137dfdc207714270b77. It changed the PyThreadState structure size, breaking the ABI in 3.9.3.
* bpo-42500: Fix recursion in or after except (GH-23568) (#24501)Mark Shannon2021-03-021-16/+0
| | | | | * Use counter, rather boolean state when handling soft overflows. (cherry picked from commit 4e7a69bdb63a104587759d7784124492dcdd496e)
* [3.9] bpo-40514: Remove --with-experimental-isolated-subinterpreters in 3.9 ↵Victor Stinner2020-05-191-4/+0
| | | | | | | (GH-20228) Remove --with-experimental-isolated-subinterpreters configure option in Python 3.9: the experiment continues in the master branch, but it's no longer needed in 3.9.
* bpo-40513: Per-interpreter GIL (GH-19943)Victor Stinner2020-05-051-0/+4
| | | | | | | | In the experimental isolated subinterpreters build mode, the GIL is now per-interpreter. Move gil from _PyRuntimeState.ceval to PyInterpreterState.ceval. new_interpreter() always get the config from the main interpreter.
* bpo-40513: Per-interpreter recursion_limit (GH-19929)Victor Stinner2020-05-051-11/+13
| | | | | | | | | | | Move recursion_limit member from _PyRuntimeState.ceval to PyInterpreterState.ceval. * Py_SetRecursionLimit() now only sets _Py_CheckRecursionLimit of ceval.c if the current Python thread is part of the main interpreter. * Inline _Py_MakeEndRecCheck() into _Py_LeaveRecursiveCall(). * Convert _Py_RecursionLimitLowerWaterMark() macro into a static inline function.
* bpo-40421: Add pyframe.h header file (GH-19755)Victor Stinner2020-04-281-2/+1
| | | | | | | | | | Add a new separated pyframe.h header file of the PyFrame public C API: it is included by Python.h. Add PyFrame_GetLineNumber() to the limited C API. Replace "struct _frame" with "PyFrameObject" in header files. PyFrameObject is now defined as struct _frame by pyframe.h which is included early enough in Python.h.
* bpo-40232: Update PyOS_AfterFork_Child() to use _PyThread_at_fork_reinit() ↵Dong-hee Na2020-04-141-2/+3
| | | | (GH-19450)
* bpo-40268: Include explicitly pycore_interp.h (GH-19505)Victor Stinner2020-04-141-2/+2
| | | | pycore_pystate.h no longer includes pycore_interp.h: it's now included explicitly in files accessing PyInterpreterState.
* bpo-40082: trip_signal() uses the main interpreter (GH-19441)Victor Stinner2020-04-081-2/+2
| | | | | | | | | | | | | | | | | | | | | | 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 Stinner2020-04-081-3/+4
| | | | | | | | | | | | | | | 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-39984: trip_signal() uses PyGILState_GetThisThreadState() (GH-19061)Victor Stinner2020-03-181-3/+1
| | | | | | | | | | | bpo-37127, bpo-39984: * trip_signal() and Py_AddPendingCall() now get the current Python thread state using PyGILState_GetThisThreadState() rather than _PyRuntimeState_GetThreadState() to be able to get it even if the GIL is released. * _PyEval_SignalReceived() now expects tstate rather than ceval. * Remove ceval parameter of _PyEval_AddPendingCall(): ceval is now get from tstate parameter.
* bpo-39984: Pass tstate to _PyEval_SignalAsyncExc() (GH-19049)Victor Stinner2020-03-181-4/+2
| | | | _PyEval_SignalAsyncExc() and _PyEval_FiniThreads() now expect tstate, instead of ceval.
* bpo-39984: _PyThreadState_DeleteCurrent() takes tstate (GH-19051)Victor Stinner2020-03-181-0/+2
| | | | | | | | | | * _PyThreadState_DeleteCurrent() now takes tstate rather than runtime. * Add ensure_tstate_not_null() helper to pystate.c. * Add _PyEval_ReleaseLock() function. * _PyThreadState_DeleteCurrent() now calls _PyEval_ReleaseLock(tstate) and frees PyThreadState memory after this call, not before. * PyGILState_Release(): rename "tcur" variable to "tstate".
* bpo-39984: Add PyInterpreterState.ceval (GH-19047)Victor Stinner2020-03-171-3/+4
| | | | | | | | | | | | | | | subinterpreters: Move _PyRuntimeState.ceval.tracing_possible to PyInterpreterState.ceval.tracing_possible: each interpreter now has its own variable. Changes: * Add _ceval_state structure. * Add PyInterpreterState.ceval field. * _PyEval_EvalFrameDefault(): add ceval2 variable (struct _ceval_state*). * Rename _PyEval_Initialize() to _PyEval_InitRuntimeState(). * Add _PyEval_InitState(). * Don't export internal _Py_FinishPendingCalls() and _PyEval_FiniThreads() functions anymore.
* bpo-39947: Move Py_EnterRecursiveCall() to internal C API (GH-18972)Victor Stinner2020-03-131-0/+60
| | | | | | Move the static inline function flavor of Py_EnterRecursiveCall() and Py_LeaveRecursiveCall() to the internal C API: they access PyThreadState attributes. The limited C API provides regular functions which hide implementation details.
* bpo-38500: Add _PyInterpreterState_SetEvalFrameFunc() (GH-17340)Victor Stinner2020-03-121-1/+1
| | | | | | | | | | | | PyInterpreterState.eval_frame function now requires a tstate (Python thread state) parameter. Add private functions to the C API to get and set the frame evaluation function: * Add tstate parameter to _PyFrameEvalFunction function type. * Add _PyInterpreterState_GetEvalFrameFunc() and _PyInterpreterState_SetEvalFrameFunc() functions. * Add tstate parameter to _PyEval_EvalFrameDefault().
* bpo-39877: PyGILState_Ensure() don't call PyEval_InitThreads() (GH-18891)Victor Stinner2020-03-091-0/+1
| | | | | | | | PyGILState_Ensure() doesn't call PyEval_InitThreads() anymore when a new Python thread state is created. The GIL is created by Py_Initialize() since Python 3.7, it's not needed to call PyEval_InitThreads() explicitly. Add an assertion to ensure that the GIL is already created.
* bpo-39877: Py_Initialize() pass tstate to PyEval_InitThreads() (GH-18884)Victor Stinner2020-03-091-0/+2
|
* bpo-38644: Pass tstate to _Py_FinishPendingCalls() (GH-17990)Victor Stinner2020-01-131-1/+1
| | | | _Py_FinishPendingCalls() now expects a tstate argument, instead of a runtime argument.
* bpo-38644: Add _PyEval_EvalCode() (GH-17183)Victor Stinner2019-11-161-0/+10
| | | _PyFunction_Vectorcall() now pass tstate to function calls.
* bpo-38644: Add _PyEval_EvalFrame() with tstate (GH-17131)Victor Stinner2019-11-141-0/+9
| | | | Add _PyEval_EvalFrame() static inline function to get eval_frame from tstate->interp.
* bpo-38353: Fix compiler warning in internal headers (GH-16573)Victor Stinner2019-10-041-3/+3
| | | | Replace "_PyRuntimeState" with "struct pyruntimestate" to avoid a warning on typedef re-definition.
* bpo-38353: Cleanup includes in the internal C API (GH-16548)Victor Stinner2019-10-021-3/+3
| | | | Use forward declaration of types to avoid includes in the internal C API. Add also comment to justify other includes.
* bpo-36710: Pass explicitly tstate in sysmodule.c (GH-14060)Victor Stinner2019-06-131-0/+3
| | | | | | | | * Replace global var Py_VerboseFlag with interp->config.verbose. * Add _PyErr_NoMemory(tstate) function. * Add tstate parameter to _PyEval_SetCoroutineOriginTrackingDepth() and move the function to the internal API. * Replace _PySys_InitMain(runtime, interp) with _PySys_InitMain(runtime, tstate).
* Revert "bpo-33608: Factor out a private, per-interpreter ↵Victor Stinner2019-06-031-8/+5
| | | | | _Py_AddPendingCall(). (gh-13714)" (GH-13780) This reverts commit 6a150bcaeb190d1731b38ab9c7a5d1a352847ddc.
* bpo-26219: per opcode cache for LOAD_GLOBAL (GH-12884)Inada Naoki2019-06-031-0/+3
| | | | | | This patch implements per opcode cache mechanism, and use it in only LOAD_GLOBAL opcode. Based on Yury's opcache3.patch in bpo-26219.

| | | | (gh-13714)
* bpo-36710: Add tstate parameter in ceval.c (GH-13547)Victor Stinner2019-05-241-0/+1
| | | | | | | | | | | | | | | | * Fix a possible reference leak in _PyErr_Print() if exception is NULL. * PyErr_BadInternalCall(): replace PyErr_Format() with _PyErr_SetString(). * Add pycore_pyerrors.h header file. * New functions: * _PyErr_Clear() * _PyErr_Fetch() * _PyErr_Print() * _PyErr_Restore() * _PyErr_SetObject() * _PyErr_SetString() * Add 'tstate' parameter to _PyEval_AddPendingCall().
* bpo-36728: Remove PyEval_ReInitThreads() from C API (GH-13241)Victor Stinner2019-05-131-0/+2
| | | | | | | | Remove the PyEval_ReInitThreads() function from the Python C API. It should not be called explicitly: use PyOS_AfterFork_Child() instead. Rename PyEval_ReInitThreads() to _PyEval_ReInitThreads() and add a 'runtime' parameter.
* bpo-36710: Add 'ceval' local variable to ceval.c (GH-12934)Victor Stinner2019-05-101-41/+12
| | | | | | | | | | | | | | | | | | | | | | | | | Add "struct _ceval_runtime_state *ceval = &_PyRuntime.ceval;" local variables to function to better highlight the dependency on the global variable _PyRuntime and to point directly to _PyRuntime.ceval field rather than on the larger _PyRuntime. Changes: * Add _PyRuntimeState_GetThreadState(runtime) macro. * Add _PyEval_AddPendingCall(ceval, ...) and _PyThreadState_Swap(gilstate, ...) functions. * _PyThreadState_GET() macro now calls _PyRuntimeState_GetThreadState() using &_PyRuntime. * Add 'ceval' parameter to COMPUTE_EVAL_BREAKER(), SIGNAL_PENDING_SIGNALS(), _PyEval_SignalAsyncExc(), _PyEval_SignalReceived() and _PyEval_FiniThreads() macros and functions. * Add 'tstate' parameter to call_function(), do_call_core() and do_raise(). * Add 'runtime' parameter to _Py_CURRENTLY_FINALIZING(), _Py_FinishPendingCalls() and _PyThreadState_DeleteExcept() macros and functions. * Declare 'runtime', 'tstate', 'ceval' and 'eval_breaker' variables as constant.
* Revert "bpo-36356: Destroy the GIL at exit (GH-12453)" (GH613006)Victor Stinner2019-04-291-3/+0
| | | This reverts commit b36e5d627d4232a01850707eb78a5067f3fd77f4.
* bpo-36356: Destroy the GIL at exit (GH-12453)Victor Stinner2019-04-291-0/+3
| | | | | | * Add _PyEval_FiniThreads2(). _PyEval_FiniThreads() now only clears the pending lock, whereas _PyEval_FiniThreads2() destroys the GIL. * pymain_free() now calls _PyEval_FiniThreads2(). * Py_FinalizeEx() now calls _PyEval_FiniThreads().
* bpo-36635: Change pyport.h for Py_BUILD_CORE_MODULE define (GH-12853)Victor Stinner2019-04-171-2/+2
| | | | | | | | | | | | | | | | | | | | Change PyAPI_FUNC(type), PyAPI_DATA(type) and PyMODINIT_FUNC macros of pyport.h when Py_BUILD_CORE_MODULE is defined. The Py_BUILD_CORE_MODULE define must be now be used to build a C extension as a dynamic library accessing Python internals: export the PyInit_xxx() function in DLL exports on Windows. Changes: * Py_BUILD_CORE_BUILTIN and Py_BUILD_CORE_MODULE now imply Py_BUILD_CORE directy in pyport.h. * ceval.c compilation now fails with an error if Py_BUILD_CORE is not defined, just to ensure that Python is build with the correct defines. * setup.py now compiles _pickle.c with Py_BUILD_CORE_MODULE define. * setup.py compiles _json.c with Py_BUILD_CORE_MODULE define, rather than Py_BUILD_CORE_BUILTIN define * PCbuild/pythoncore.vcxproj: Add Py_BUILD_CORE_BUILTIN define.

* bpo-33608: Factor out a private, per-interpreter _Py_AddPendingCall(). ↵Eric Snow2019-02-241-5/+13
| | | | | | | (GH-11617) This involves moving the global "pending calls" state to PyInterpreterState. https://bugs.python.org/issue33608
* bpo-35423: Stop using the "pending calls" machinery for signals. (gh-10972)Eric Snow2019-01-111-0/+2
| | | | | This change separates the signal handling trigger in the eval loop from the "pending calls" machinery. There is no semantic change and the difference in performance is insignificant. The change makes both components less confusing. It also eliminates the risk of changes to the pending calls affecting signal handling. This is particularly relevant for some upcoming pending calls changes I have in the works.
* bpo-35081: Internal headers require Py_BUILD_CORE (GH-10363)Victor Stinner2018-11-091-0/+4
| | | | | | | | | * All internal header files now require Py_BUILD_CORE or Py_BUILD_CORE_BUILTIN to be defined. * _json.c is now compiled with Py_BUILD_CORE_BUILTIN to access pycore_accu.h header. * Add an example to Modules/Setup to show how to build _json as a built-in module; it requires non trivial compiler options.
* bpo-35081: Add pycore_ prefix to internal header files (GH-10263)Victor Stinner2018-10-311-0/+52
* Rename Include/internal/ header files: * pyatomic.h -> pycore_atomic.h * ceval.h -> pycore_ceval.h * condvar.h -> pycore_condvar.h * context.h -> pycore_context.h * pygetopt.h -> pycore_getopt.h * gil.h -> pycore_gil.h * hamt.h -> pycore_hamt.h * hash.h -> pycore_hash.h * mem.h -> pycore_mem.h * pystate.h -> pycore_state.h * warnings.h -> pycore_warnings.h * PCbuild project, Makefile.pre.in, Modules/Setup: add the Include/internal/ directory to the search paths of header files. * Update includes. For example, replace #include "internal/mem.h" with #include "pycore_mem.h".
