* bpo-32399: Starting with AIX6.1 there is support in libc.a for uuid ↵Michael Felt2017-12-301-6/+17
| | | | | | | | | | | | (RFC4122) (#4974) Starting with AIX6.1 there is support in libc.a for uuid (RFC4122) This patch provides the changes needed for this integration with the OS. On AIX the base function is uuid_create() rather than uuid_generate_time() The AIX uuid_t typedef is more aligned to the UUID field based definition while the Linux typedef that is more aligned with UUID bytes (or perhaps UUID bytes_le) definitions.

* bpo-32030: Add _Py_FindEnvConfigValue() (#4963)Victor Stinner2017-12-211-72/+9
| | | | | | | | | | | | | | | Add a new _Py_FindEnvConfigValue() function: code shared between Windows and Unix implementations of _PyPathConfig_Calculate() to read the pyenv.cfg file. _Py_FindEnvConfigValue() now uses _Py_DecodeUTF8_surrogateescape() instead of using a Python Unicode string, the Python API must not be used early during Python initialization. Same change in Unix search_for_exec_prefix(): use _Py_DecodeUTF8_surrogateescape(). Cleanup also encode_current_locale(): PyMem_RawFree/PyMem_Free can be called with NULL. Fix also "NUL byte" => "NULL byte" typo.
* bpo-32030: Add _Py_EncodeLocaleRaw() (#4961)Victor Stinner2017-12-212-4/+4
| | | | | | | | | | | | Replace Py_EncodeLocale() with _Py_EncodeLocaleRaw() in: * _Py_wfopen() * _Py_wreadlink() * _Py_wrealpath() * _Py_wstat() * pymain_open_filename() These functions are called early during Python intialization, only the RAW memory allocator must be used.

* bpo-32030: Fix usage of memory allocators (#4953)Victor Stinner2017-12-201-7/+19
| | | | | | | | | * _Py_InitializeCore() doesn't call _PyMem_SetupAllocators() anymore if the PYTHONMALLOC environment variable is not set. * pymain_cmdline() now sets the allocator to the default, instead of setting the allocator in subfunctions. * Py_SetStandardStreamEncoding() now calls _PyMem_SetDefaultAllocator() to get a known allocator, to be able to release the memory with the same allocator.

* bpo-32030: Complete _PyCoreConfig_Read() (#4946)Victor Stinner2017-12-201-325/+366
| | | | | | | | | | * Add _PyCoreConfig.install_signal_handlers * Remove _PyMain.config: _PyMainInterpreterConfig usage is now restricted to pymain_init_python_main(). * Rename _PyMain.core_config to _PyMain.config * _PyMainInterpreterConfig_Read() now creates the xoptions dictionary from the core config * Fix _PyMainInterpreterConfig_Read(): don't replace xoptions and argv if they are already set.
* bpo-32030: Add _PyCoreConfig.warnoptions (#4936)Victor Stinner2017-12-201-421/+446
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Merge _PyCoreConfig_ReadEnv() into _PyCoreConfig_Read(), and _Py_CommandLineDetails usage is now restricted to pymain_cmdline(). Changes: * _PyCoreConfig: Add nxoption, xoptions, nwarnoption and warnoptions * Add _PyCoreConfig.program: argv[0] or "" * Move filename, command, module and xoptions from _Py_CommandLineDetails to _PyMain. xoptions _Py_OptList becomes (int, wchar_t**) list. * Add pymain_cmdline() function * Rename copy_argv() to copy_wstrlist(). Rename clear_argv() to clear_wstrlist(). Remove _Py_OptList structure: use (int, wchar_t**) list instead. * Rename pymain_set_flag_from_env() to pymain_get_env_flag() * Rename pymain_set_flags_from_env() to pymain_get_env_flags() * _PyMainInterpreterConfig_Read() now creates the warnoptions from _PyCoreConfig.warnoptions * Inline pymain_add_warning_dev_mode() and pymain_add_warning_bytes_flag() into config_init_warnoptions() * Inline pymain_get_program_name() into _PyCoreConfig_Read() * _Py_CommandLineDetails: Replace warning_options with nwarnoption and warnoptions. Replace env_warning_options with nenv_warnoption and env_warnoptions. * pymain_warnings_envvar() now has a single implementation for Windows and Unix: use config_get_env_var_dup() to also get the variable as wchar_t* on Unix.
* bpo-31901: atexit callbacks should be run at subinterpreter shutdown (#4611)Marcel Plch2017-12-201-32/+40

| | | | | | | | | | | Fix compiler warnings in Py_FinalizeEx(): only define variables if they are needed, add #ifdef. Other cleanup changes: * _PyWarnings_InitWithConfig() is no more needed: call _PyWarnings_Init() instead. * Inline pymain_init_main_interpreter() in its caller. This subfunction is no more justifed.

* bpo-19764: Implemented support for subprocess.Popen(close_fds=True) on ↵Segev Finer2017-12-182-24/+260
| | | | | | | | | | | | | | | | | Windows (#1218) Even though Python marks any handles it opens as non-inheritable there is still a race when using `subprocess.Popen` since creating a process with redirected stdio requires temporarily creating inheritable handles. By implementing support for `subprocess.Popen(close_fds=True)` we fix this race. In order to implement this we use PROC_THREAD_ATTRIBUTE_HANDLE_LIST which is available since Windows Vista. Which allows to pass an explicit list of handles to inherit when creating a process. This commit also adds `STARTUPINFO.lpAttributeList["handle_list"]` which can be used to control PROC_THREAD_ATTRIBUTE_HANDLE_LIST directly.

* bpo-29240, bpo-32030: Py_Main() re-reads config if encoding changes (#4899)Victor Stinner2017-12-162-54/+248
| | | | | | | | | | | | | | | | | | 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-32030: Rewrite _PyMainInterpreterConfig (#4854)Victor Stinner2017-12-142-129/+211
| | | | | | | | | | | | | | | | | | | | _PyMainInterpreterConfig now contains Python objects, whereas _PyCoreConfig contains wchar_t* strings. 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
* bpo-32030: Add _PyPathConfig_ComputeArgv0() (#4845)Victor Stinner2017-12-131-16/+91
| | | | | | | | | | | | | | | | Changes: * Split _PySys_SetArgvWithError() into subfunctions for Py_Main(): * Create the Python list object * Set sys.argv to the list * Compute argv0 * Prepend argv0 to sys.path * Add _PyPathConfig_ComputeArgv0() * Remove _PySys_SetArgvWithError() * Py_Main() now splits the code to compute sys.argv/path0 and the code to update the sys module: add pymain_compute_argv() subfunction.
* bpo-32296: Implement asyncio.get_event_loop and _get_running_loop in C. (#4827)Yury Selivanov2017-12-132-8/+323
| | | | | | | | asyncio.get_event_loop(), and, subsequently asyncio._get_running_loop() are one of the most frequently executed functions in asyncio. They also can't be sped up by third-party event loops like uvloop. When implemented in C they become 4x faster.
* pymain_set_sys_argv() now copies argv (#4838)Victor Stinner2017-12-131-28/+58
| | | | | | | | | | bpo-29240, bpo-32030: * Rename pymain_set_argv() to pymain_set_sys_argv() * pymain_set_sys_argv() now creates of copy of argv and modify the copy, rather than modifying pymain->argv * Call pymain_set_sys_argv() earlier: before pymain_run_python(), but after pymain_get_importer(). * Add _PySys_SetArgvWithError() to handle errors
* bpo-29240: PEP 540: Add a new UTF-8 Mode (#855)Victor Stinner2017-12-133-56/+129
| | | | | | | | | | | | | | | | | | | | | | * 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.
