* | bpo-32030: Simplify _PyCoreConfig_INIT macro (#4728)Victor Stinner2017-12-052-35/+7
|/ | | | | | | * Simplify _PyCoreConfig_INIT, _PyMainInterpreterConfig_INIT, _PyPathConfig_INIT macros: no need to set fields to 0/NULL, it's redundant (the C language sets them to 0/NULL for us). * Fix typo: pymain_run_statup() => pymain_run_startup() * Remove a few XXX/TODO

* bpo-32030: _PyPathConfig_Init() sets home and program_name (#4673)Victor Stinner2017-12-022-2/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | _PyPathConfig_Init() now also initialize home and program_name: * Rename existing _PyPathConfig_Init() to _PyPathConfig_Calculate(). Add a new _PyPathConfig_Init() function in pathconfig.c which handles the _Py_path_config variable and call _PyPathConfig_Calculate(). * Add home and program_name fields to _PyPathConfig.home * _PyPathConfig_Init() now initialize home and program_name from main_config * Py_SetProgramName(), Py_SetPythonHome() and Py_GetPythonHome() now calls Py_FatalError() on failure, instead of silently ignoring failures. * config_init_home() now gets directly _Py_path_config.home to only get the value set by Py_SetPythonHome(), or NULL if Py_SetPythonHome() was not called. * config_get_program_name() now gets directly _Py_path_config.program_name to only get the value set by Py_SetProgramName(), or NULL if Py_SetProgramName() was not called. * pymain_init_python() doesn't call Py_SetProgramName() anymore, _PyPathConfig_Init() now always sets the program name * Call _PyMainInterpreterConfig_Read() in pymain_parse_cmdline_envvars_impl() to control the memory allocator * C API documentation: it's no more safe to call Py_GetProgramName() before Py_Initialize().
* bpo-32030: Add Python/pathconfig.c (#4668)Victor Stinner2017-12-012-1/+4
| | | | | | | * Factorize code from PC/getpathp.c and Modules/getpath.c to remove duplicated code * rename pathconfig_clear() to _PyPathConfig_Clear() * Inline _PyPathConfig_Fini() in pymain_impl() and then remove it, since it's a oneliner
* bpo-32030: Don't call _PyPathConfig_Fini() in Py_FinalizeEx() (#4667)Victor Stinner2017-12-011-1/+1
| | | | | | | | | | | | | | | Changes: * _PyPathConfig_Fini() cannot be called in Py_FinalizeEx(). Py_Initialize() and Py_Finalize() can be called multiple times, but it must not "forget" parameters set by Py_SetProgramName(), Py_SetPath() or Py_SetPythonHome(), whereas _PyPathConfig_Fini() clear all these parameters. * config_get_program_name() and calculate_program_full_path() now also decode paths using Py_DecodeLocale() to use the surrogateescape error handler, rather than decoding using mbstowcs() which is strict. * Change _Py_CheckPython3() prototype: () => (void) * Truncate a few lines which were too long
* bpo-32030: Cleanup "path config" code (#4663)Victor Stinner2017-12-011-0/+16
| | | | | | | | | | * Rename PyPathConfig structure to _PyPathConfig and move it to Include/internal/pystate.h * Rename path_config to _Py_path_config * _PyPathConfig: Rename program_name field to program_full_path * Add assert(str != NULL); to _PyMem_RawWcsdup(), _PyMem_RawStrdup() and _PyMem_Strdup(). * Rename calculate_path() to pathconfig_global_init(). The function now does nothing if it's already initiallized.
* bpo-32030: Rework memory allocators (#4625)Victor Stinner2017-11-291-1/+9
| | | | | | | | | | | | | | | | | | | | * Fix _PyMem_SetupAllocators("debug"): always restore allocators to the defaults, rather than only caling _PyMem_SetupDebugHooks(). * Add _PyMem_SetDefaultAllocator() helper to set the "default" allocator. * Add _PyMem_GetAllocatorsName(): get the name of the allocators * main() now uses debug hooks on memory allocators if Py_DEBUG is defined, rather than calling directly malloc() * Document default memory allocators in C API documentation * _Py_InitializeCore() now fails with a fatal user error if PYTHONMALLOC value is an unknown memory allocator, instead of failing with a fatal internal error. * Add new tests on the PYTHONMALLOC environment variable * Add support.with_pymalloc() * Add the _testcapi.WITH_PYMALLOC constant and expose it as support.with_pymalloc(). * sysconfig.get_config_var('WITH_PYMALLOC') doesn't work on Windows, so replace it with support.with_pymalloc(). * pythoninfo: add _testcapi collector for pymem
* bpo-32150: Expand tabs to spaces in C files. (#4583)Serhiy Storchaka2017-11-2815-148/+148

* 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)

* 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.
