* bpo-31440: Changed default module search path for windowsgauravbackback2017-11-281-2/+2
|
* bpo-24641: Improved error message for JSON unserializible keys. (#4364)Serhiy Storchaka2017-11-251-2/+3
| | | | | Also updated an example for default() in the module docstring. Removed quotes around type name in other error messages.
* bpo-32030: Add _PyPathConfig_Init() (#4551)Victor Stinner2017-11-252-183/+249
| | | | | | | | | | | | | | * 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 Stinner2017-11-242-33/+48
| | | | | | * 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 Stinner2017-11-242-82/+85
| | | | | | | | | | | | | | | | | | 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-32030: Fix calculate_path() on macOS (#4526)Victor Stinner2017-11-231-8/+9

* bpo-32030: Rewrite calculate_path() (#4521)Victor Stinner2017-11-232-369/+542
| | | | | | | | | | | | | | | | | * 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-32030: Add _PyMainInterpreterConfig.pythonhome (#4513)Victor Stinner2017-11-232-17/+70
| | | | | | | | | | | | * 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 Stinner2017-11-232-18/+18
| | | | Move _PyCoreConfig.module_search_path_env to _PyMainInterpreterConfig structure.
* bpo-32030: Add _PyCoreConfig.module_search_path_env (#4504)Victor Stinner2017-11-222-29/+106
| | | | | | | | | | | 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 Stinner2017-11-211-1/+9
| | | | | | 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 Stinner2017-11-211-7/+2
| | | | | | | | | | 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-32043: New "developer mode": "-X dev" option (#4413)Victor Stinner2017-11-161-0/+10
| | | | | | | | | | | | | Add a new "developer mode": new "-X dev" command line option to enable debug checks at runtime. Changes: * Add unit tests for -X dev * test_cmd_line: replace test.support with support. * Fix _PyRuntimeState_Fini(): Use the same memory allocator than _PyRuntimeState_Init(). * Fix _PyMem_GetDefaultRawAllocator()
* bpo-32037: Use the INT opcode for 32-bit integers in protocol 0 pickles. (#4407)Serhiy Storchaka2017-11-161-23/+23

* bpo-32030: Enhance Py_Main() (#4412)Victor Stinner2017-11-164-248/+343
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Stinner2017-11-152-376/+825
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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-32025: Add time.thread_time() (#4410)Antoine Pitrou2017-11-151-0/+117

* bpo-31927: Fix bugs in socketmodule.c on NetBSD and other issues. (#4235)Serhiy Storchaka2017-11-092-65/+71
| | | | | | | * Fix compilation of the socket module on NetBSD 8. * Fix the assertion failure or reading arbitrary data when parse a AF_BLUETOOTH address on NetBSD and DragonFly BSD. * Fix other potential errors and make the code more reliable.
* Replace KB unit with KiB (#4293)Victor Stinner2017-11-086-8/+8
| | | | | | | | | | | 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-31933: fix blake2 multi-byte params on big endian platforms (#4250)Jack O'Connor2017-11-032-4/+8
| | | | | | | | | | | | All Blake2 params have to be encoded in little-endian byte order. For the two multi-byte integer params, leaf_length and node_offset, that means that assigning a native-endian integer to them appears to work on little-endian platforms, but gives the wrong result on big-endian. The current libb2 API doesn't make that very clear, and @sneves is working on new API functions in the GH issue above. In the meantime, we can work around the problem by explicitly assigning little-endian values to the parameter block. See https://github.com/BLAKE2/libb2/issues/12.
* bpo-30057: Fix potential missed signal in signal.signal(). (#4258)Antoine Pitrou2017-11-031-1/+4
| | | Bug report and patch by Jeroen Demeyer.
* bpo-31926: fix missing *_METHODDEF statements by argument clinic (#4230)Tal Einat2017-11-032-5/+5
| | | | | | | | | When a single .c file contains several functions and/or methods with the same name, a safety _METHODDEF #define statement is generated only for one of them. This fixes the bug by using the full name of the function to avoid duplicates rather than just the name.
* bpo-31784: Implement PEP 564: add time.time_ns() (#3989)Victor Stinner2017-11-022-138/+349
| | | | | | | | | | | | | | | | | | | | | | | | | 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-31917: Add 3 new clock identifiers (#4207)Victor Stinner2017-11-021-0/+9

* Remove nested comments in blake2 (#4173)Lars Viklund2017-11-011-2/+4
| | | | | | | | | | | Replace occurence of nested comments in blake2 reference implementation with preprocessor directive for disabling unused code. `blake2s-load-xop.h` is conditionally pulled in only on chips with XOP support, among others the AMD Bulldozer. The malformed comments in the source file breaks the build of `hashlib`'s `_blake2` on GCC 6.3.0. Official reference code on github uses `#if` so this change should be uncontroversial.
* bpo-25720: Fix the method for checking pad state of curses WINDOW (#4164)Masayuki Yamamoto2017-11-011-8/+16
| | | | | | | | | 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-18835: Cleanup pymalloc (#4200)Victor Stinner2017-10-311-7/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | Cleanup pymalloc: * Rename _PyObject_Alloc() to pymalloc_alloc() * Rename _PyObject_FreeImpl() to pymalloc_free() * Rename _PyObject_Realloc() to pymalloc_realloc() * pymalloc_alloc() and pymalloc_realloc() don't fallback on the raw allocator anymore, it now must be done by the caller * Add "success" and "failed" labels to pymalloc_alloc() and pymalloc_free() * pymalloc_alloc() and pymalloc_free() don't update num_allocated_blocks anymore: it should be done in the caller * _PyObject_Calloc() is now responsible to fill the memory block allocated by pymalloc with zeros * Simplify pymalloc_alloc() prototype * _PyObject_Realloc() now calls _PyObject_Malloc() rather than calling directly pymalloc_alloc() _PyMem_DebugRawAlloc() and _PyMem_DebugRawRealloc(): * document the layout of a memory block * don't increase the serial number if the allocation failed * check for integer overflow before computing the total size * add a 'data' variable to make the code easiler to follow test_setallocators() of _testcapimodule.c now test also the context.
* bpo-31893: Fix errors in b9052a0f91d2e83bbc27267247a5920c82b242a3. (#4196)Serhiy Storchaka2017-10-311-4/+4
| | | | | * Fix a compilation error on FreeBSD. * Fix the data attribute size on Mac OS X.
* bpo-31893: Fixed select.kqueue(). (#4166)Serhiy Storchaka2017-10-311-47/+71
| | | | * Fixed the layout of the kqueue_event structure on OpenBSD and NetBSD. * Fixed the comparison of the kqueue_event objects.
* bpo-31891: Fix building the curses module on NetBSD. (#4165)Serhiy Storchaka2017-10-311-33/+40

* 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-16135: Cleanup: Code rot left over from OS/2 support (GH-4147)Erik Bray2017-10-272-12/+1
| | | | Remove dangling references to PYCC_VACPP that are not relelvant since removal of OS/2 support.
* Fix _socket module compilation on Cygwin. (#4137)Erik Bray2017-10-271-1/+1
