* bpo-31901: atexit callbacks should be run at subinterpreter shutdown (#4611)Marcel Plch2017-12-201-1/+0
| | | | Change atexit behavior and PEP-489 multiphase init support.
* bpo-32030: Fix compilation on FreeBSD, #include <fenv.h> (#4919)Victor Stinner2017-12-181-8/+0
| | | | | * main.c: add missing #include <fenv.h> on FreeBSD * indent also other #ifdef in main.c * cleanup Programs/python.c
* bpo-29240, bpo-32030: Py_Main() re-reads config if encoding changes (#4899)Victor Stinner2017-12-161-90/+1
| | | | | | | | | | | | | | | | | | bpo-29240, bpo-32030: If the encoding change (C locale coerced or UTF-8 Mode changed), Py_Main() now reads again the configuration with the new encoding. Changes: * Add _Py_UnixMain() called by main(). * Rename pymain_free_pymain() to pymain_clear_pymain(), it can now be called multipled times. * Rename pymain_parse_cmdline_envvars() to pymain_read_conf(). * Py_Main() now clears orig_argc and orig_argv at exit. * Remove argv_copy2, Py_Main() doesn't modify argv anymore. There is no need anymore to get two copies of the wchar_t** argv. * _PyCoreConfig: add coerce_c_locale and coerce_c_locale_warn. * Py_UTF8Mode is now initialized to -1. * Locale coercion (PEP 538) now respects -I and -E options.
* bpo-29240: PEP 540: Add a new UTF-8 Mode (#855)Victor Stinner2017-12-131-9/+14
| | | | | | | | | | | | | | | | | | | | | | * Add -X utf8 command line option, PYTHONUTF8 environment variable and a new sys.flags.utf8_mode flag. * If the LC_CTYPE locale is "C" at startup: enable automatically the UTF-8 mode. * Add _winapi.GetACP(). encodings._alias_mbcs() now calls _winapi.GetACP() to get the ANSI code page * locale.getpreferredencoding() now returns 'UTF-8' in the UTF-8 mode. As a side effect, open() now uses the UTF-8 encoding by default in this mode. * Py_DecodeLocale() and Py_EncodeLocale() now use the UTF-8 encoding in the UTF-8 Mode. * Update subprocess._args_from_interpreter_flags() to handle -X utf8 * Skip some tests relying on the current locale if the UTF-8 mode is enabled. * Add test_utf8mode.py. * _Py_DecodeUTF8_surrogateescape() gets a new optional parameter to return also the length (number of wide characters). * pymain_get_global_config() and pymain_set_global_config() now always copy flag values, rather than only copying if the new value is greater than the old value.
* bpo-20891: Fix PyGILState_Ensure() (#4650)Victor Stinner2017-11-301-0/+49
| | | | | | | When PyGILState_Ensure() is called in a non-Python thread before PyEval_InitThreads(), only call PyEval_InitThreads() after calling PyThreadState_New() to fix a crash. Add an unit test in test_embed.
* bpo-32030: Rework memory allocators (#4625)Victor Stinner2017-11-291-13/+6
| | | | | | | | | | | | | | | | | | | | * 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-32096: Ensure new embedding test can find the encodings module (GH-4566)Nick Coghlan2017-11-261-1/+2

* bpo-32096: Remove obj and mem from _PyRuntime (#4532)Victor Stinner2017-11-241-0/+23
| | | | | | | | | | | | | | | | | 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: Split Py_Main() into subfunctions (#4399)Victor Stinner2017-11-152-4/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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-31877: Add _Py_LegacyLocaleDetected and _PyCoerceLegacyLocale to ↵Erik Bray2017-10-271-14/+10
| | | | | | | | 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-28180: Implementation for PEP 538 (#659)Nick Coghlan2017-06-111-0/+37
| | | | | | | | | | - new PYTHONCOERCECLOCALE config setting - coerces legacy C locale to C.UTF-8, C.utf8 or UTF-8 by default - always uses C.UTF-8 on Android - uses `surrogateescape` on stdin and stdout in the coercion target locales - configure option to disable locale coercion at build time - configure option to disable C locale warning at build time
