* bpo-43268: _Py_IsMainInterpreter() now expects interp (GH-24577)Victor Stinner2021-02-191-2/+2
| | | | The _Py_IsMainInterpreter() function now expects interp rather than tstate.
* bpo-40826: Add _PyOS_InterruptOccurred(tstate) function (GH-20599)Victor Stinner2020-06-031-0/+3
| | | | | | | | | | | | my_fgets() now calls _PyOS_InterruptOccurred(tstate) to check for pending signals, rather calling PyOS_InterruptOccurred(). my_fgets() is called with the GIL released, whereas PyOS_InterruptOccurred() must be called with the GIL held. test_repl: use text=True and avoid SuppressCrashReport in test_multiline_string_parsing(). Fix my_fgets() on Windows: fgets(fp) does crash if fileno(fp) is closed.
* PyOS_AfterFork_Child() uses PyStatus (GH-20596)Victor Stinner2020-06-021-2/+5
| | | | | | | | PyOS_AfterFork_Child() helper functions now return a PyStatus: PyOS_AfterFork_Child() is now responsible to handle errors. * Move _PySignal_AfterFork() to the internal C API * Add #ifdef HAVE_FORK on _PyGILState_Reinit(), _PySignal_AfterFork() and _PyInterpreterState_DeleteExceptMain().
* bpo-40826: Add _Py_EnsureTstateNotNULL() macro (GH-20571)Victor Stinner2020-06-011-1/+18
| | | | Add _Py_EnsureTstateNotNULL(tstate) macro: call Py_FatalError() if tstate is NULL, the error message contains the current function name.
* bpo-40522: _PyThreadState_Swap() sets autoTSSkey (GH-19939)Victor Stinner2020-05-051-2/+18
| | | | | | | | | | | | | | | | | | In the experimental isolated subinterpreters build mode, _PyThreadState_GET() gets the autoTSSkey variable and _PyThreadState_Swap() sets the autoTSSkey variable. * Add _PyThreadState_GetTSS() * _PyRuntimeState_GetThreadState() and _PyThreadState_GET() return _PyThreadState_GetTSS() * PyEval_SaveThread() sets the autoTSSkey variable to current Python thread state rather than NULL. * eval_frame_handle_pending() doesn't check that _PyThreadState_Swap() result is NULL. * _PyThreadState_Swap() gets the current Python thread state with _PyThreadState_GetTSS() rather than _PyRuntimeGILState_GetThreadState(). * PyGILState_Ensure() no longer checks _PyEval_ThreadsInitialized() since it cannot access the current interpreter.
* bpo-40268: Rename _PyInterpreterState_GET_UNSAFE() (GH-19509)Victor Stinner2020-04-141-1/+2
| | | | | | | 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 Stinner2020-04-141-2/+1
| | | | pycore_pystate.h no longer includes pycore_interp.h: it's now included explicitly in files accessing PyInterpreterState.
* bpo-40241: Add pycore_interp.h header (GH-19499)Victor Stinner2020-04-131-165/+1
| | | | Move PyInterpreterState and related functions to a new internal pycore_interp.h header file.
* bpo-40268: Add pycore_runtime.h header file (GH-19493)Victor Stinner2020-04-131-121/+1
| | | | | | 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 Stinner2020-04-131-0/+4
| | | | | | | | Don't access PyInterpreterState.config member directly anymore, but use new functions: * _PyInterpreterState_GetConfig() * _PyInterpreterState_SetConfig() * _Py_GetConfig()
* bpo-40082: trip_signal() uses the main interpreter (GH-19441)Victor Stinner2020-04-081-4/+9
| | | | | | | | | | | | | | | | | | | | | | 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-37127: Remove _pending_calls.finishing (GH-19439)Victor Stinner2020-04-081-1/+0
|
* bpo-39946: Remove _PyThreadState_GetFrame (GH-19094)Victor Stinner2020-03-201-4/+0
| | | | | Remove _PyRuntime.getframe hook and remove _PyThreadState_GetFrame macro which was an alias to _PyRuntime.getframe. They were only exposed by the internal C API. Remove also PyThreadFrameGetter type.
* bpo-40010: Optimize pending calls in multithreaded applications (GH-19091)Victor Stinner2020-03-201-2/+8
| | | | | | | | | | | | | | | If a thread different than the main thread schedules a pending call (Py_AddPendingCall()), the bytecode evaluation loop is no longer interrupted at each bytecode instruction to check for pending calls which cannot be executed. Only the main thread can execute pending calls. Previously, the bytecode evaluation loop was interrupted at each instruction until the main thread executes pending calls. * Add _Py_ThreadCanHandlePendingCalls() function. * SIGNAL_PENDING_CALLS() now only sets eval_breaker to 1 if the current thread can execute pending calls. Only the main thread can execute pending calls.
* bpo-40010: COMPUTE_EVAL_BREAKER() checks for subinterpreter (GH-19087)Victor Stinner2020-03-201-1/+27
| | | | | | | | | COMPUTE_EVAL_BREAKER() now also checks if the Python thread state belongs to the main interpreter. Don't break the evaluation loop if there are pending signals but the Python thread state it belongs to a subinterpeter. * Add _Py_IsMainThread() function. * Add _Py_ThreadCanHandleSignals() function.
* bpo-39984: Move pending calls to PyInterpreterState (GH-19066)Victor Stinner2020-03-191-4/+4
| | | | | | | | | | | | | | | | | If Py_AddPendingCall() is called in a subinterpreter, the function is now scheduled to be called from the subinterpreter, rather than being called from the main interpreter. Each subinterpreter now has its own list of scheduled calls. * Move pending and eval_breaker fields from _PyRuntimeState.ceval to PyInterpreterState.ceval. * new_interpreter() now calls _PyEval_InitThreads() to create pending calls lock. * Fix Py_AddPendingCall() for subinterpreters. It now calls _PyThreadState_GET() which works in a subinterpreter if the caller holds the GIL, and only falls back on PyGILState_GetThisThreadState() if _PyThreadState_GET() returns NULL.
* bpo-39984: Add PyInterpreterState.ceval (GH-19047)Victor Stinner2020-03-171-6/+10
| | | | | | | | | | | | | | | 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-38500: Add _PyInterpreterState_SetEvalFrameFunc() (GH-17340)Victor Stinner2020-03-121-2/+0
| | | | | | | | | | | | 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: _PyRuntimeState.finalizing becomes atomic (GH-18816)Victor Stinner2020-03-061-6/+17
| | | | | | | | | | | | Convert _PyRuntimeState.finalizing field to an atomic variable: * Rename it to _finalizing * Change its type to _Py_atomic_address * Add _PyRuntimeState_GetFinalizing() and _PyRuntimeState_SetFinalizing() functions * Remove _Py_CURRENTLY_FINALIZING() function: replace it with testing directly _PyRuntimeState_GetFinalizing() value Convert _PyRuntimeState_GetThreadState() to static inline function.
* Add PyInterpreterState.fs_codec.utf8 (GH-18367)Victor Stinner2020-02-051-0/+1
| | | | | | Add a fast-path for UTF-8 encoding in PyUnicode_EncodeFSDefault() and PyUnicode_DecodeFSDefaultAndSize(). Add _PyUnicode_FiniEncodings() helper function for _PyUnicode_Fini().
* bpo-38858: Small integer per interpreter (GH-17315)Victor Stinner2019-12-171-0/+12
| | | | | | | | | | | | 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: _PyImport_FixupExtensionObject() handles subinterpreters (GH-17350)Victor Stinner2019-11-221-0/+6
| | | | | 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 _Py_IsMainInterpreter(tstate) (GH-17293)Victor Stinner2019-11-201-0/+2
|
* bpo-36854: Move _PyRuntimeState.gc to PyInterpreterState (GH-17287)Victor Stinner2019-11-201-4/+3
| | | | | * Rename _PyGC_InitializeRuntime() to _PyGC_InitState() * finalize_interp_clear() now also calls _PyGC_Fini() in subinterpreters (clear the GC state).
* bpo-36710: Add PyInterpreterState.runtime field (GH-17270)Victor Stinner2019-11-201-1/+5
| | | | | | | | | | | 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".
* bpo-36876: Moved Parser/listnode.c statics to interpreter state. (GH-16328)Vinay Sajip2019-11-071-0/+9
|
* bpo-38353: Cleanup includes in the internal C API (GH-16548)Victor Stinner2019-10-021-10/+3
| | | | Use forward declaration of types to avoid includes in the internal C API. Add also comment to justify other includes.
* bpo-38070: Add _PyRuntimeState.preinitializing (GH-16245)Victor Stinner2019-09-171-3/+8
| | | | | | Add _PyRuntimeState.preinitializing field: set to 1 while Py_PreInitialize() is running. _PyRuntimeState: rename also pre_initialized field to preinitialized.
* bpo-37392: Remove sys.setcheckinterval() (GH-14355)Victor Stinner2019-06-251-3/+0
| | | | | | | Remove sys.getcheckinterval() and sys.setcheckinterval() functions. They were deprecated since Python 3.2. Use sys.getswitchinterval() and sys.setswitchinterval() instead. Remove also check_interval field of the PyInterpreterState structure.
* bpo-36710: Use tstate in pylifecycle.c (GH-14249)Victor Stinner2019-06-191-1/+1
| | | | In pylifecycle.c: pass tstate argument, rather than interp argument, to functions.
* bpo-36710: Add tstate parameter in import.c (GH-14218)Victor Stinner2019-06-191-0/+3
| | | | | | | | | | | | | * Add 'tstate' parameter to many internal import.c functions. * _PyImportZip_Init() now gets 'tstate' parameter rather than 'interp'. * Add 'interp' parameter to _PyState_ClearModules() and rename it to _PyInterpreterState_ClearModules(). * Move private _PyImport_FindBuiltin() to the internal C API; add 'tstate' parameter to it. * Remove private _PyImport_AddModuleObject() from the C API: use public PyImport_AddModuleObject() instead. * Remove private _PyImport_FindExtensionObjectEx() from the C API: use private _PyImport_FindExtensionObject() instead.

* bpo-36710: Add 'ceval' local variable to ceval.c (GH-12934)Victor Stinner2019-05-101-6/+53
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.
