* bpo-36763: _PyInitError always use int for exitcode (GH-13360)Victor Stinner2019-05-162-14/+15
| | | | | | | | | | | | | | | | | We cannot use "unsigned int" for exitcode on Windows, since Py_Main() and _Py_RunMain() always return an "int". Changes: * _PyPathConfig_ComputeSysPath0() now returns -1 if an exception is raised. * pymain_run_python() no longer uses _PyInitError but display the exception and set exitcode to 1 in case of error. * Fix _Py_RunMain(): return an exitcode rather than calling exit() on pymain_run_python() failure. * _Py_ExitInitError() no longer uses ExitProcess() on Windows, use exit() on all platforms. * _Py_ExitInitError() now fails with a fatal error if 'err' is not an error not an exit.
* bpo-36900: Replace global conf vars with config (GH-13299)Victor Stinner2019-05-144-24/+28
| | | | | | Replace global configuration variables with core_config read from the current interpreter. Cleanup dynload_hpux.c.

* bpo-36728: Remove PyEval_ReInitThreads() from C API (GH-13241)Victor Stinner2019-05-131-2/+1
| | | | | | | | 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 Stinner2019-05-104-260/+292
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

* bpo-35983: skip trashcan for subclasses (GH-11841)Jeroen Demeyer2019-05-102-8/+8
| | | | | Add new trashcan macros to deal with a double deallocation that could occur when the `tp_dealloc` of a subclass calls the `tp_dealloc` of a base class and that base class uses the trashcan mechanism. Patch by Jeroen Demeyer.

| | | | | | | | | | | | | | | | | _PyCoreConfig: Change filesystem_encoding, filesystem_errors, stdio_encoding and stdio_errors fields type from char* to wchar_t*. Changes: * PyInterpreterState: replace fscodec_initialized (int) with fs_codec structure. * Add get_error_handler_wide() and unicode_encode_utf8() helper functions. * Add error_handler parameter to unicode_encode_locale() and unicode_decode_locale(). * Remove _PyCoreConfig_SetString(). * Rename _PyCoreConfig_SetWideString() to _PyCoreConfig_SetString(). * Rename _PyCoreConfig_SetWideStringFromString() to _PyCoreConfig_DecodeLocale().

| | | | | | * 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-36475: Finalize PyEval_AcquireLock() and PyEval_AcquireThread() properly ↵Joannah Nanjekye2019-04-291-12/+16
| | | | | | | | (GH-12667) PyEval_AcquireLock() and PyEval_AcquireThread() now terminate the current thread if called while the interpreter is finalizing, making them consistent with PyEval_RestoreThread(), Py_END_ALLOW_THREADS, and PyGILState_Ensure().

| | | | Add 'state' or 'runtime' parameter to functions in gcmodule.c to avoid to rely directly on the global variable _PyRuntime.
* bpo-36710: Add runtime variable in pystate.c (GH-12956)Victor Stinner2019-04-251-142/+219
| | | | Add 'gilstate', 'runtime' or 'xidregistry' parameter to many functions on pystate.c to avoid lying on _PyRuntime global.
* bpo-36722: Debug build loads libraries built in release mode (GH-12952)Victor Stinner2019-04-251-2/+3
| | | | In debug build, import now also looks for C extensions compiled in release mode and for C extensions compiled in the stable ABI.
* bpo-36710: Add runtime variable to Py_InitializeEx() (GH-12939)Victor Stinner2019-04-244-68/+92
| | | | | | | | Py_InitializeEx() now uses a runtime variable passed to subfunctions, rather than working directly on the global variable _PyRuntime. Add 'runtime' parameter to _PyCoreConfig_Write(), _PySys_Create(), _PySys_InitMain(), _PyGILState_Init(), emit_stderr_warning_for_legacy_locale() and other subfunctions.

* bpo-36635: Change pyport.h for Py_BUILD_CORE_MODULE define (GH-12853)Victor Stinner2019-04-171-0/+4
| | | | | | | | | | | | | | | | | | | | 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-32849: Fix is_valid_fd() on FreeBSD (GH-12852)Victor Stinner2019-04-171-15/+23
| | | | | | | Fix Python Initialization code on FreeBSD to detect properly when stdin file descriptor (fd 0) is invalid. On FreeBSD, fstat() must be used to check if stdin (fd 0) is valid. dup(0) doesn't fail if stdin is invalid in some cases.
* bpo-36623: Clean parser headers and include files (GH-12253)Pablo Galindo2019-04-132-3/+0

| | | | | _Py_AddPendingCall()." (gh-12806) This reverts commit f13c5c8b9401a9dc19e95d8b420ee100ac022208 (gh-12360).
* bpo-33608: Factor out a private, per-interpreter _Py_AddPendingCall(). ↵Eric Snow2019-04-124-97/+118
| | | | | (gh-12360) This is effectively an un-revert of #11617 and #12024 (reverted in #12159). Portions of those were merged in other PRs (with lower risk) and this represents the remainder. Note that I found 3 different bugs in the original PRs and have fixed them here.

| | | | | | | | | | | | | | | Fix time.mktime() error handling on AIX for year before 1970. Other changes: * mktime(): rename variable 'buf' to 'tm'. * _PyTime_localtime(): * Use "localtime" rather than "ctime" in the error message (specific to AIX). * Always initialize errno to 0 just in case if localtime_r() doesn't set errno on error. * On AIX, avoid abs() which is limited to int type. * EINVAL constant is now always available.
