* bpo-35081: Add Include/internal/pycore_tupleobject.h (GH-10705)Victor Stinner2018-11-251-0/+18
| | | | Move _PyTuple_ITEMS() to a new header file: Include/internal/pycore_tupleobject.h
* bpo-34523: Fix C locale coercion on FreeBSD CURRENT (GH-10672)Victor Stinner2018-11-231-0/+8
| | | | | | | | bpo-34523, bpo-35290: C locale coercion now resets the Python internal "force ASCII" mode. This change fix the filesystem encoding on FreeBSD CURRENT, which has a new "C.UTF-8" locale, when the UTF-8 mode is disabled. Add _Py_ResetForceASCII(): _Py_SetLocaleFromEnv() now calls it.
* bpo-35059: Add _PyObject_CAST() macro (GH-10645)Victor Stinner2018-11-221-2/+2
| | | | Add _PyObject_CAST() and _PyVarObject_CAST() macros to cast argument to PyObject* and PyVarObject* properly.
* bpo-35059: Convert _PyObject_GC_TRACK() to inline function (GH-10643)Victor Stinner2018-11-221-24/+46
| | | | | | | | | | | | | * Add _PyObject_ASSERT_FROM() and _PyObject_ASSERT_FAILED_MSG() macros. * PyObject_GC_Track() now calls _PyObject_ASSERT_FAILED_MSG(), instead of Py_FatalError(), if the object is already tracked, to dump more information on error. * _PyObject_GC_TRACK() no longer checks if the object is already tracked at runtime, use an assertion instead for best performances; PyObject_GC_Track() still checks at runtime. * pycore_object.h now includes pycore_pystate.h. * Convert _PyObject_GC_TRACK() and _PyObject_GC_UNTRACK() macros to inline functions.
* bpo-35081: Add Include/internal/pycore_object.h (GH-10640)Victor Stinner2018-11-211-0/+56
| | | | Move _PyObject_GC_TRACK() and _PyObject_GC_UNTRACK() from Include/objimpl.h to Include/internal/pycore_object.h.
* bpo-28604: Fix localeconv() for different LC_MONETARY (GH-10606)Victor Stinner2018-11-201-0/+7
| | | | | | | | | | | | | | | | | | | | | locale.localeconv() now sets temporarily the LC_CTYPE locale to the LC_MONETARY locale if the two locales are different and monetary strings are non-ASCII. This temporary change affects other threads. Changes: * locale.localeconv() can now set LC_CTYPE to LC_MONETARY to decode monetary fields. * Add LocaleInfo.grouping_buffer: copy localeconv() grouping string since it can be replaced anytime if a different thread calls localeconv(). * _Py_GetLocaleconvNumeric() now requires a "struct lconv *" structure, so locale.localeconv() now longer calls localeconv() twice. Moreover, the function now requires all arguments to be non-NULL. * Rename STATIC_LOCALE_INFO_INIT to LocaleInfo_STATIC_INIT. * Move _Py_GetLocaleconvNumeric() definition from fileutils.h to pycore_fileutils.h. pycore_fileutils.h now includes locale.h. * The _locale module is now built with Py_BUILD_CORE defined.

| | | | | | | | | | | | | | | | | | | | | | | | | | * Move "GC" macros together: * PyObject_IS_GC() * _Py_AS_GC() * _PyObject_GC_IS_TRACKED() * _PyObject_GC_MAY_BE_TRACKED() * Mark other GC macros as internal (#ifdef Py_BUILD_CORE): * _PyGCHead_NEXT(g), _PyGCHead_SET_NEXT(g, p) * _PyGCHead_PREV(g), _PyGCHead_SET_PREV(g, p) * _PyGCHead_FINALIZED(g), _PyGCHead_SET_FINALIZED(g) * _PyGC_FINALIZED(o), _PyGC_SET_FINALIZED(o) * _PyObject_GC_TRACK(o), _PyObject_GC_UNTRACK(o) * _PyGC_PREV_MASK_FINALIZED * _PyGC_PREV_MASK_COLLECTING * _PyGC_PREV_SHIFT * _PyGC_PREV_MASK * Replace _PyGC_generation0 with _PyRuntime.gc.generation0 * _queuemodule.c: replace _PyObject_GC_UNTRACK() with with PyObject_GC_UnTrack() * Document that _PyObject_GC_TRACK() _PyObject_GC_UNTRACK() macros have been removed from the public C API.
* bpo-35081: Rename internal headers (GH-10275)Victor Stinner2018-11-124-1/+1
| | | | | | | | | | | | | | Rename Include/internal/ headers: * pycore_hash.h -> pycore_pyhash.h * pycore_lifecycle.h -> pycore_pylifecycle.h * pycore_mem.h -> pycore_pymem.h * pycore_state.h -> pycore_pystate.h Add missing headers to Makefile.pre.in and PCbuild: * pycore_condvar.h. * pycore_hamt.h * pycore_pyhash.h
* bpo-35081: Internal headers require Py_BUILD_CORE (GH-10363)Victor Stinner2018-11-0914-12/+44
| | | | | | | | | * All internal header files now require Py_BUILD_CORE or Py_BUILD_CORE_BUILTIN to be defined. * _json.c is now compiled with Py_BUILD_CORE_BUILTIN to access pycore_accu.h header. * Add an example to Modules/Setup to show how to build _json as a built-in module; it requires non trivial compiler options.
* bpo-35081: Add pycore_fileutils.h (GH-10371)Victor Stinner2018-11-061-0/+36
| | | | Move Py_BUILD_CORE code from Include/fileutils.h to a new Include/internal/pycore_fileutils.h file.
* bpo-35081: Add _PyCoreConfig_AsDict() (GH-10362)Victor Stinner2018-11-061-0/+4
| | | | | | | | | | | | _testcapimodule.c must not include pycore_pathconfig.h, since it's an internal header files. Changes: * Add _PyCoreConfig_AsDict() function to coreconfig.c. * Remove pycore_pathconfig.h include from _testcapimodule.h. * pycore_pathconfig.h now requires Py_BUILD_CORE to be defined. * _testcapimodule.c compilation now fails if it's built with Py_BUILD_CORE defined.
* bpo-35081: And pycore_lifecycle.h and pycore_pathconfig.h (GH-10273)Victor Stinner2018-11-013-47/+120
| | | | | | | | | | * And pycore_lifecycle.h and pycore_pathconfig.h headers to Include/internal/ * Move Py_BUILD_CORE specific code from coreconfig.h and pylifecycle.h to pycore_pathconfig.h and pycore_lifecycle.h * Move _Py_wstrlist_XXX() definitions and _PyPathConfig code from pycore_state.h to pycore_pathconfig.h * Move "Init" and "Fini" function definitions from pylifecycle.c to pycore_lifecycle.h.
* bpo-35081: Move accu.h to Include/internal/pycore_accu.h (GH-10271)Victor Stinner2018-11-011-0/+35
| | | | | | | The accu.h header is no longer part of the Python C API: it has been moved to the "internal" headers which are restricted to Python itself. Replace #include "accu.h" with #include "pycore_accu.h".
* bpo-35081: Add _PyThreadState_GET() internal macro (GH-10266)Victor Stinner2018-11-011-0/+34
| | | | | | | | | | | | | | | | | | | | | | | | | If Py_BUILD_CORE is defined, the PyThreadState_GET() macro access _PyRuntime which comes from the internal pycore_state.h header. Public headers must not require internal headers. Move PyThreadState_GET() and _PyInterpreterState_GET_UNSAFE() from Include/pystate.h to Include/internal/pycore_state.h, and rename PyThreadState_GET() to _PyThreadState_GET() there. The PyThreadState_GET() macro of pystate.h is now redefined when pycore_state.h is included, to use the fast _PyThreadState_GET(). Changes: * Add _PyThreadState_GET() macro * Replace "PyThreadState_GET()->interp" with _PyInterpreterState_GET_UNSAFE() * Replace PyThreadState_GET() with _PyThreadState_GET() in internal C files (compiled with Py_BUILD_CORE defined), but keep PyThreadState_GET() in the public header files. * _testcapimodule.c: replace PyThreadState_GET() with PyThreadState_Get(); the module is not compiled with Py_BUILD_CORE defined. * pycore_state.h now requires Py_BUILD_CORE to be defined.
* bpo-35081: Add pycore_ prefix to internal header files (GH-10263)Victor Stinner2018-10-3111-8/+8
| | | | | | | | | | | | | | | | | | | | * Rename Include/internal/ header files: * pyatomic.h -> pycore_atomic.h * ceval.h -> pycore_ceval.h * condvar.h -> pycore_condvar.h * context.h -> pycore_context.h * pygetopt.h -> pycore_getopt.h * gil.h -> pycore_gil.h * hamt.h -> pycore_hamt.h * hash.h -> pycore_hash.h * mem.h -> pycore_mem.h * pystate.h -> pycore_state.h * warnings.h -> pycore_warnings.h * PCbuild project, Makefile.pre.in, Modules/Setup: add the Include/internal/ directory to the search paths of header files. * Update includes. For example, replace #include "internal/mem.h" with #include "pycore_mem.h".
* bpo-35081: Move Py_BUILD_CORE code to internal/mem.h (GH-10249)Victor Stinner2018-10-311-0/+12
| | | | | * Add #include "internal/mem.h" to C files using _PyMem_SetDefaultAllocator(). * Include/internal/mem.h now requires Py_BUILD_CORE to be defined.
* bpo-35081: Move Include/pyatomic.c to Include/internal/ (GH-10239)Victor Stinner2018-10-304-5/+548
| | | Add pyatomic.h to the VS project (it wasn't referenced).
* bpo-34651: Only allow the main interpreter to fork. (gh-9279)Eric Snow2018-09-141-0/+1
| | | | | When os.fork() is called (on platforms that support it) all threads but the current one are destroyed in the child process. Consequently we must ensure that all but the associated interpreter are likewise destroyed. The main interpreter is critical for runtime operation, so we must ensure that fork only happens in the main interpreter. https://bugs.python.org/issue34651
* bpo-31650: Remove _Py_CheckHashBasedPycsMode global config var (GH-8608)Victor Stinner2018-08-011-6/+0
| | | | | | | | bpo-31650, bpo-34170: Replace _Py_CheckHashBasedPycsMode with _PyCoreConfig._check_hash_pycs_mode. Modify PyInit__imp() and zipimport to get the parameter from the current interpreter core configuration. Remove Include/internal/import.h file.
* bpo-34170: Add Python/coreconfig.c for _PyCoreConfig (GH-8607)Victor Stinner2018-08-011-0/+6
| | | | | | | * Add Include/coreconfig.h * Move config_*() and _PyCoreConfig_*() functions from Modules/main.c to a new Python/coreconfig.c file. * Inline _Py_ReadHashSeed() into config_init_hash_seed() * Move global configuration variables to coreconfig.c
* bpo-34170: Add _PyCoreConfig.isolated (GH-8417)Victor Stinner2018-07-241-3/+3
| | | | | | | | | | | | | | | * _PyCoreConfig: add isolated and site_import attributes * Replace Py_IgnoreEnvironment with config->ignore_environment when reading the current configuration * _PyCoreConfig_Read() now sets ignore_environment, utf8_mode, isolated and site_import from Py_IgnoreEnvironment, Py_UTF8Mode, Py_IsolatedFlag and Py_NoSiteFlag * _Py_InitializeCore() now sets Py_xxx flags from the configuration * pymain_read_conf() now uses _PyCoreConfig_Copy() to save/restore the configuration. * Rename _disable_importlib of _PyCoreConfig to _install_importlib * _PyCoreConfig_SetGlobalConfig() now also set Py_HashRandomizationFlag * Replace !Py_NoSiteFlag with core_config->site_import
* bpo-34170: _PyCoreConfig_Read() leaves Py_IsolatedFlag unchanged (GH-8361)Victor Stinner2018-07-211-1/+9
| | | | | | | | | | * _PyCoreConfig_Read() no longer directly modifies Py_IsolatedFlag and Py_NoSiteFlag global configuration flags. The function now requires two pointers to integer, so these flags can be set later, to avoid side effets in _PyCoreConfig_Read(). * pathconfig_global_init() now leaves Py_IsolatedFlag and Py_NoSiteFlag unchanged. * Fix pathconfig_global_init(): avoid computing the path configuration twice, use _PyCoreConfig_SetPathConfig().
* bpo-34170: Rework _PyCoreConfig_Read() to avoid side effect (GH-8353)Victor Stinner2018-07-211-3/+7
| | | | | | | | | | | | | | | | | | | | | | | | | Rework _PyCoreConfig_Read() function which *reads* core configuration to not *modify* the path configuration. A new _PyCoreConfig_SetPathConfig() function now recreates the path configuration from the core configuration. This function is now called very late in _Py_InitializeCore(), just before calling initimport(). Changes: * Add _PyCoreConfig.dll_path * Py_SetPath() now fails with a fatal python error on memory allocation failure. * Rename _PyPathConfig_Calculate() to _PyPathConfig_Calculate_impl() * Replace _PyPathConfig_Init() with _PyPathConfig_Calculate(): the function now requires a _PyPathConfig * Add _PyPathConfig_SetGlobal() to set the _Py_path_config global variable. * Add _PyCoreConfig_InitPathConfig(): compute the path configuration * Add _PyCoreConfig_SetPathConfig(): set path configuration from core configuration * Rename wstrlist_append() to _Py_wstrlist_append() * _Py_wstrlist_append() now handles integer overflow.
* bpo-33615: Re-enable a subinterpreter test. (gh-7251)Eric Snow2018-06-021-3/+4
| | | For bpo-32604 I added extra subinterpreter-related tests (see #6914), which caused a few buildbots to crash. This patch fixes the crash by ensuring that refcounts in channels are handled properly.

Core config: * Rename _PyMainInterpreterConfig_ReadEnv() to _PyCoreConfig_ReadEnv() * Move 3 strings from _PyMainInterpreterConfig to _PyCoreConfig: module_search_path_env, home, program_name. * Add _PyCoreConfig_Clear() * _PyPathConfig_Calculate() now takes core config rather than main config * _PyMainInterpreterConfig_Read() now requires also a core config Main config: * Add _PyMainInterpreterConfig.module_search_path: sys.path list * Add _PyMainInterpreterConfig.argv: sys.argv list * _PyMainInterpreterConfig_Read() now computes module_search_path
* closes bpo-31650: PEP 552 (Deterministic pycs) implementation (#4575)Benjamin Peterson2017-12-092-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | Python now supports checking bytecode cache up-to-dateness with a hash of the source contents rather than volatile source metadata. See the PEP for details. While a fairly straightforward idea, quite a lot of code had to be modified due to the pervasiveness of pyc implementation details in the codebase. Changes in this commit include: - The core changes to importlib to understand how to read, validate, and regenerate hash-based pycs. - Support for generating hash-based pycs in py_compile and compileall. - Modifications to our siphash implementation to support passing a custom key. We then expose it to importlib through _imp. - Updates to all places in the interpreter, standard library, and tests that manually generate or parse pyc files to grok the new format. - Support in the interpreter command line code for long options like --check-hash-based-pycs. - Tests and documentation for all of the above.

| | | | | | | | | | | | | | | | | | | | | | | | | | _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 Stinner2017-12-011-0/+4

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 Stinner2017-11-151-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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)

| | | | | | | | | | | 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-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.
