* bpo-32030: Add _PyPathConfig_Init() (#4551)Victor Stinner2017-11-251-2/+3
| | | | | | | | | | | | | | * Add _PyPathConfig_Init() and _PyPathConfig_Fini() * Remove _Py_GetPathWithConfig() * _PyPathConfig_Init() returns _PyInitError to allow to handle errors properly * Add pathconfig_clear() * Windows calculate_path_impl(): replace Py_FatalError() with _PyInitError * Py_FinalizeEx() now calls _PyPathConfig_Fini() to release memory * Fix _Py_InitializeMainInterpreter() regression: don't initialize path config if _disable_importlib is false * PyPathConfig now uses dynamically allocated memory
* bpo-32030: Add _PyMainInterpreterConfig.program_name (#4548)Victor Stinner2017-11-241-0/+2
| | | | | | * Py_Main() now calls Py_SetProgramName() earlier to be able to get the program name in _PyMainInterpreterConfig_ReadEnv(). * Rename prog to program_name * Rename progpath to program_name
* bpo-32030: Add _PyMainInterpreterConfig_ReadEnv() (#4542)Victor Stinner2017-11-243-11/+17
| | | | | | | | | | | | | | | | | | Py_GetPath() and Py_Main() now call _PyMainInterpreterConfig_ReadEnv() to share the same code to get environment variables. Changes: * Add _PyMainInterpreterConfig_ReadEnv() * Add _PyMainInterpreterConfig_Clear() * Add _PyMem_RawWcsdup() * _PyMainInterpreterConfig: rename pythonhome to home * Rename _Py_ReadMainInterpreterConfig() to _PyMainInterpreterConfig_Read() * Use _Py_INIT_USER_ERR(), instead of _Py_INIT_ERR(), for decoding errors: the user is able to fix the issue, it's not a bug in Python. Same change was made in _Py_INIT_NO_MEMORY(). * Remove _Py_GetPythonHomeWithConfig()
* bpo-32125: Remove Py_UseClassExceptionsFlag flag (#4544)Victor Stinner2017-11-241-1/+0
| | | This flag was deprecated and wasn't used anymore since Python 2.0.
* bpo-32096: Remove obj and mem from _PyRuntime (#4532)Victor Stinner2017-11-243-493/+0
| | | | | | | | | | | | | | | | | bpo-32096, bpo-30860: Partially revert the commit 2ebc5ce42a8a9e047e790aefbf9a94811569b2b6: * Move structures back from Include/internal/mem.h to Objects/obmalloc.c * Remove _PyObject_Initialize() and _PyMem_Initialize() * Remove Include/internal/pymalloc.h * Add test_capi.test_pre_initialization_api(): Make sure that it's possible to call Py_DecodeLocale(), and then call Py_SetProgramName() with the decoded string, before Py_Initialize(). PyMem_RawMalloc() and Py_DecodeLocale() can be called again before _PyRuntimeState_Init(). Co-Authored-By: Eric Snow <ericsnowcurrently@gmail.com>
* bpo-32030: Rewrite calculate_path() (#4521)Victor Stinner2017-11-231-16/+22
| | | | | | | | | | | | | | | | | * calculate_path() rewritten in Modules/getpath.c and PC/getpathp.c * Move global variables into a new PyPathConfig structure. * calculate_path(): * Split the huge calculate_path() function into subfunctions. * Add PyCalculatePath structure to pass data between subfunctions. * Document PyCalculatePath fields. * Move cleanup code into a new calculate_free() subfunction * calculate_init() now handles Py_DecodeLocale() failures properly * calculate_path() is now atomic: only replace PyPathConfig (path_config) at once on success. * _Py_GetPythonHomeWithConfig() now returns an error on failure * Add _Py_INIT_NO_MEMORY() helper: report a memory allocation failure * Coding style fixes (PEP 7)
* bpo-29040: Support building Android with Unified Headers (GH-4492)xdegaye2017-11-231-1/+3

* bpo-32030: Add _PyMainInterpreterConfig.pythonhome (#4513)Victor Stinner2017-11-233-2/+13
| | | | | | | | | | | | * Py_Main() now reads the PYTHONHOME environment variable * Add _Py_GetPythonHomeWithConfig() private function * Add _PyWarnings_InitWithConfig() * init_filters() doesn't get the current core configuration from the current interpreter or Python thread anymore. Pass explicitly the configuration to _PyWarnings_InitWithConfig(). * _Py_InitializeCore() now fails on _PyWarnings_InitWithConfig() failure. * Pass configuration as constant
* bpo-32030: Move PYTHONPATH to _PyMainInterpreterConfig (#4511)Victor Stinner2017-11-232-4/+4
| | | | Move _PyCoreConfig.module_search_path_env to _PyMainInterpreterConfig structure.
* bpo-32030: Add _PyCoreConfig.module_search_path_env (#4504)Victor Stinner2017-11-222-2/+10
| | | | | | | | | | | Changes: * Py_Main() initializes _PyCoreConfig.module_search_path_env from the PYTHONPATH environment variable. * PyInterpreterState_New() now initializes core_config and config fields * Compute sys.path a little bit ealier in _Py_InitializeMainInterpreter() and new_interpreter() * Add _Py_GetPathWithConfig() private function.
* bpo-32030: Add more options to _PyCoreConfig (#4485)Victor Stinner2017-11-212-9/+12
| | | | | | Py_Main() now handles two more -X options: * -X showrefcount: new _PyCoreConfig.show_ref_count field * -X showalloccount: new _PyCoreConfig.show_alloc_count field
* bpo-32089: Fix warnings filters in dev mode (#4482)Victor Stinner2017-11-211-1/+3
| | | | | | | | | | The developer mode (-X dev) now creates all default warnings filters to order filters in the correct order to always show ResourceWarning and make BytesWarning depend on the -b option. Write a functional test to make sure that ResourceWarning is logged twice at the same location in the developer mode. Add a new 'dev_mode' field to _PyCoreConfig.
* bpo-32030: Enhance Py_Main() (#4412)Victor Stinner2017-11-163-2/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Stinner2017-11-155-11/+52
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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)
* bpo-31979: Simplify transforming decimals to ASCII (#4336)Serhiy Storchaka2017-11-131-9/+7

* Replace KB unit with KiB (#4293)Victor Stinner2017-11-081-3/+3
| | | | | | | | | | | 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.

* bpo-31784: Implement PEP 564: add time.time_ns() (#3989)Victor Stinner2017-11-021-1/+19
| | | | | | | | | | | | | | | | | | | | | | | | | Add new time functions: * time.clock_gettime_ns() * time.clock_settime_ns() * time.monotonic_ns() * time.perf_counter_ns() * time.process_time_ns() * time.time_ns() Add new _PyTime functions: * _PyTime_FromTimespec() * _PyTime_FromNanosecondsObject() * _PyTime_FromTimeval() Other changes: * Add also os.times() tests to test_os. * pytime_fromtimeval() and pytime_fromtimeval() now return _PyTime_MAX or _PyTime_MIN on overflow, rather than undefined behaviour * _PyTime_FromNanoseconds() parameter type changes from long long to _PyTime_t

* bpo-25720: Fix the method for checking pad state of curses WINDOW (#4164)Masayuki Yamamoto2017-11-011-7/+12
| | | | | | | | | Modify the code to use ncurses is_pad() instead of checking WINDOW _flags field. If your platform does not provide the is_pad(), the existing way that checks the field will be enabled. Note: This change does not drop support for platforms where do not have both WINDOW _flags field and is_pad().
* bpo-31891: Fix building the curses module on NetBSD. (#4165)Serhiy Storchaka2017-10-311-10/+6

* bpo-31877: Add _Py_LegacyLocaleDetected and _PyCoerceLegacyLocale to ↵Erik Bray2017-10-271-0/+6
| | | | | | | | pylifecycle.h (GH-4134) Only declaring these as interns inside the CLI's main C module caused build problems on some platforms (notably Cygwin), so this switches them to a regular underscore prefixed "private" C API declaration.

* bpo-30768: Recompute timeout on interrupted lock (GH-4103)Victor Stinner2017-10-242-7/+17
| | | | | | | | | | | | | | | | Fix the pthread+semaphore implementation of PyThread_acquire_lock_timed() when called with timeout > 0 and intr_flag=0: recompute the timeout if sem_timedwait() is interrupted by a signal (EINTR). See also the PEP 475. The pthread implementation of PyThread_acquire_lock() now fails with a fatal error if the timeout is larger than PY_TIMEOUT_MAX, as done in the Windows implementation. The check prevents any risk of overflow in PyThread_acquire_lock(). Add also PY_DWORD_MAX constant.
* Move exc state to generator. Fixes bpo-25612 (#1773)Mark Shannon2017-10-224-12/+27

* bpo-31558: Add gc.freeze() (#3705)brainfvck2017-10-161-0/+2
| | | | | Freeze all the objects tracked by gc - move them to a permanent generation and ignore all the future collections. This can be used before a POSIX fork() call to make the gc copy-on-write friendly or to speed up collection.
* bpo-31773: _PyTime_GetPerfCounter() uses _PyTime_t (GH-3983)Victor Stinner2017-10-161-3/+3
| | | | | | | | * Rewrite win_perf_counter() to only use integers internally. * Add _PyTime_MulDiv() which compute "ticks * mul / div" in two parts (int part and remaining) to prevent integer overflow. * Clock frequency is checked at initialization for integer overflow. * Enhance also pymonotonic() to reduce the precision loss on macOS (mach_absolute_time() clock).
* bpo-31773: time.perf_counter() uses again double (GH-3964)Victor Stinner2017-10-121-11/+12
| | | | | | | | time.clock() and time.perf_counter() now use again C double internally. Remove also _PyTime_GetWinPerfCounterWithInfo(): use _PyTime_GetPerfCounterDoubleWithInfo() instead on Windows.
* bpo-31415: Add _PyTime_GetPerfCounter() and use it for -X importtime (#3936)Victor Stinner2017-10-101-0/+16
| | | | | * Add _PyTime_GetPerfCounter() * Use _PyTime_GetPerfCounter() for -X importtime
* bpo-25658: Implement PEP 539 for Thread Specific Storage (TSS) API (GH-1362)Masayuki Yamamoto2017-10-062-10/+64
| | | | | | | | | 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

* bpo-31574: importlib dtrace (#3749)Christian Heimes2017-09-292-0/+6
| | | | | Importlib was instrumented with two dtrace probes to profile import timing. Signed-off-by: Christian Heimes <christian@python.org>

* bpo-31497: Add private helper _PyType_Name(). (#3630)Serhiy Storchaka2017-09-171-0/+1
| | | | This function returns the last component of tp_name after a dot. Returns tp_name itself if it doesn't contain a dot.
* bpo-28411: Support other mappings in PyInterpreterState.modules. (#3593)Eric Snow2017-09-151-0/+6
| | | | | The concrete PyDict_* API is used to interact with PyInterpreterState.modules in a number of places. This isn't compatible with all dict subclasses, nor with other Mapping implementations. This patch switches the concrete API usage to the corresponding abstract API calls. We also add a PyImport_GetModule() function (and some other helpers) to reduce a bunch of code duplication.
* bpo-31464: asdl_c.py no longer emits trailing spaces in Python-ast.h. (#3568)Serhiy Storchaka2017-09-151-59/+59
|
* bpo-31338 (#3374)Barry Warsaw2017-09-151-0/+2
| | | | | | | * Add Py_UNREACHABLE() as an alias to abort(). * Use Py_UNREACHABLE() instead of assert(0) * Convert more unreachable code to use Py_UNREACHABLE() * Document Py_UNREACHABLE() and a few other macros.
* bpo-28411: Isolate PyInterpreterState.modules (#3575)Eric Snow2017-09-142-3/+18
| | | | | A bunch of code currently uses PyInterpreterState.modules directly instead of PyImport_GetModuleDict(). This complicates efforts to make changes relative to sys.modules. This patch switches to using PyImport_GetModuleDict() uniformly. Also, a number of related uses of sys.modules are updated for uniformity for the same reason. Note that this code was already reviewed and merged as part of #1638. I reverted that and am now splitting it up into more focused parts.
* bpo-30860: Fix a refleak. (#3567)Eric Snow2017-09-142-4/+1
| | | | | Resolves bpo-31420. (This was accidentally reverted when in #3565.)
