* bpo-19764: Implemented support for subprocess.Popen(close_fds=True) on ↵Segev Finer2017-12-182-6/+55
| | | | | | | | | | | | | | | | | 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 Stinner2017-12-161-3/+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-32329, bpo-32030: * The -R option now turns on hash randomization when the PYTHONHASHSEED environment variable is set to 0 Previously, the option was ignored. * sys.flags.hash_randomization is now properly set to 0 when hash randomization is turned off by PYTHONHASHSEED=0. * _PyCoreConfig_ReadEnv() now reads the PYTHONHASHSEED environment variable. _Py_HashRandomization_Init() now only apply the configuration, it doesn't read PYTHONHASHSEED anymore.

* bpo-29240: PEP 540: Add a new UTF-8 Mode (#855)Victor Stinner2017-12-135-4/+63
| | | | | | | | | | | | | | | | | | | | | | * 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-32230: Set sys.warnoptions with -X dev (#4820)Victor Stinner2017-12-123-13/+38
| | | | | | | | | | | | | | Rather than supporting dev mode directly in the warnings module, this instead adjusts the initialisation code to add an extra 'default' entry to sys.warnoptions when dev mode is enabled. This ensures that dev mode behaves *exactly* as if `-Wdefault` had been passed on the command line, including in the way it interacts with `sys.warnoptions`, and with other command line flags like `-bb`. Fix also bpo-20361: have -b & -bb options take precedence over any other warnings options. Patch written by Nick Coghlan, with minor modifications of Victor Stinner.

* closes bpo-31650: PEP 552 (Deterministic pycs) implementation (#4575)Benjamin Peterson2017-12-097-4/+158
| | | | | | | | | | | | | | | | | | | | | | | | | 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.
