| | | | | | | | | | | * bpo-6532: Make the thread id an unsigned integer. From C API side the type of results of PyThread_start_new_thread() and PyThread_get_thread_ident(), the id parameter of PyThreadState_SetAsyncExc(), and the thread_id field of PyThreadState changed from "long" to "unsigned long". * Restore a check in thread_get_ident().

* | faulthandler: add Windows exception handlerVictor Stinner2016-03-231-64/+189
| | | | | | | | | | | | Issue #23848: On Windows, faulthandler.enable() now also installs an exception handler to dump the traceback of all Python threads on any Windows exception, not only on UNIX signals (SIGSEGV, SIGFPE, SIGABRT).

|/ | | | | | | | | | | Issue #26563: * Add _PyGILState_GetInterpreterStateUnsafe() function: the single PyInterpreterState used by this process' GILState implementation. * Enhance _Py_DumpTracebackThreads() to retrieve the interpreter state from autoInterpreterState in last resort. The function now accepts NULL for interp and current_tstate parameters. * test_faulthandler: fix a ResourceWarning when test is interrupted by CTRL+c

* Add _PyThreadState_UncheckedGet()Victor Stinner2016-01-201-1/+1
| | | | | | | | | | | | | | | | | | | Issue #26154: Add a new private _PyThreadState_UncheckedGet() function which gets the current thread state, but don't call Py_FatalError() if it is NULL. Python 3.5.1 removed the _PyThreadState_Current symbol from the Python C API to no more expose complex and private atomic types. Atomic types depends on the compiler or can even depend on compiler options. The new function _PyThreadState_UncheckedGet() allows to get the variable value without having to care of the exact implementation of atomic types. Changes: * Replace direct usage of the _PyThreadState_Current variable with a call to _PyThreadState_UncheckedGet(). * In pystate.c, replace direct usage of the _PyThreadState_Current variable with the PyThreadState_GET() macro for readability. * Document also PyThreadState_Get() in pystate.h

| | | | | | | | | | | | | | | | | | | | to its signal handlers. Use also _Py_write_noraise() instead of write() to retry write() if it is interrupted by a signal (fail with EINTR). faulthandler.dump_traceback() also calls PyErr_CheckSignals() to call the Python signal handler if a signal was received.
