* bpo-32030: Enhance Py_Main() (#4412)Victor Stinner2017-11-161-34/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Parse more env vars in Py_Main(): * Add more options to _PyCoreConfig: * faulthandler * tracemalloc * importtime * Move code to parse environment variables from _Py_InitializeCore() to Py_Main(). This change fixes a regression from Python 3.6: PYTHONUNBUFFERED is now read before calling pymain_init_stdio(). * _PyFaulthandler_Init() and _PyTraceMalloc_Init() now take an argument to decide if the module has to be enabled at startup. * tracemalloc_start() is now responsible to check the maximum number of frames. Other changes: * Cleanup Py_Main(): * Rename some pymain_xxx() subfunctions * Add pymain_run_python() subfunction * Cleanup Py_NewInterpreter() * _PyInterpreterState_Enable() now reports failure * init_hash_secret() now considers pyurandom() failure as an "user error": don't fail with abort(). * pymain_optlist_append() and pymain_strdup() now sets err on memory allocation failure.
* bpo-32030: Split Py_Main() into subfunctions (#4399)Victor Stinner2017-11-151-32/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Don't use "Python runtime" anymore to parse command line options or to get environment variables: pymain_init() is now a strict separation. * Use an error message rather than "crashing" directly with Py_FatalError(). Limit the number of calls to Py_FatalError(). It prepares the code to handle errors more nicely later. * Warnings options (-W, PYTHONWARNINGS) and "XOptions" (-X) are now only added to the sys module once Python core is properly initialized. * _PyMain is now the well identified owner of some important strings like: warnings options, XOptions, and the "program name". The program name string is now properly freed at exit. pymain_free() is now responsible to free the "command" string. * Rename most methods in Modules/main.c to use a "pymain_" prefix to avoid conflits and ease debug. * Replace _Py_CommandLineDetails_INIT with memset(0) * Reorder a lot of code to fix the initialization ordering. For example, initializing standard streams now comes before parsing PYTHONWARNINGS. * Py_Main() now handles errors when adding warnings options and XOptions. * Add _PyMem_GetDefaultRawAllocator() private function. * Cleanup _PyMem_Initialize(): remove useless global constants: move them into _PyMem_Initialize(). * Call _PyRuntime_Initialize() as soon as possible: _PyRuntime_Initialize() now returns an error message on failure. * Add _PyInitError structure and following macros: * _Py_INIT_OK() * _Py_INIT_ERR(msg) * _Py_INIT_USER_ERR(msg): "user" error, don't abort() in that case * _Py_INIT_FAILED(err)
* Replace KB unit with KiB (#4293)Victor Stinner2017-11-081-2/+2
| | | | | | | | | | | kB (*kilo* byte) unit means 1000 bytes, whereas KiB ("kibibyte") means 1024 bytes. KB was misused: replace kB or KB with KiB when appropriate. Same change for MB and GB which become MiB and GiB. Change the output of Tools/iobench/iobench.py. Round also the size of the documentation from 5.5 MB to 5 MiB.
* faulthandler: use _PyTime_t rather than double for timeout (#4139)Victor Stinner2017-10-271-20/+31
| | | | | | | | | | | | | | | | | Use the _PyTime_t type rather than double for the faulthandler timeout in dump_traceback_later(). This change should fix the following Coverity warning: CID 1420311: Incorrect expression (UNINTENDED_INTEGER_DIVISION) Dividing integer expressions "9223372036854775807LL" and "1000LL", and then converting the integer quotient to type "double". Any remainder, or fractional part of the quotient, is ignored. if ((timeout * 1e6) >= (double) PY_TIMEOUT_MAX) { The warning comes from (double)PY_TIMEOUT_MAX with: #define PY_TIMEOUT_MAX (PY_LLONG_MAX / 1000)
* bpo-31701: faulthandler: ignore MSC and COM Windows exception (#3929)Victor Stinner2017-10-091-3/+19

* bpo-25658: Implement PEP 539 for Thread Specific Storage (TSS) API (GH-1362)Masayuki Yamamoto2017-10-061-1/+1
| | | | | | | | | See PEP 539 for details. Highlights of changes: - Add Thread Specific Storage (TSS) API - Document the Thread Local Storage (TLS) API as deprecated - Update code that used TLS API to use TSS API

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().

* 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

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.
