* gh-98433: Fix quadratic time idna decoding. (#99092)Gregory P. Smith2022-11-081-17/+25
| | | | | | | | There was an unnecessary quadratic loop in idna decoding. This restores the behavior to linear. This also adds an early length check in IDNA decoding to outright reject huge inputs early on given the ultimate result is defined to be 63 or fewer characters.
* bpo-46659: Fix the MBCS codec alias on Windows (GH-31218)Victor Stinner2022-02-221-4/+7

* bpo-46659: Update the test on the mbcs codec alias (GH-31168)Victor Stinner2022-02-061-3/+4
| | | | | | | | | | | encodings registers the _alias_mbcs() codec search function before the search_function() codec search function. Previously, the _alias_mbcs() was never used. Fix the test_codecs.test_mbcs_alias() test: use the current ANSI code page, not a fake ANSI code page number. Remove the test_site.test_aliasing_mbcs() test: the alias is now implemented in the encodings module, no longer in the site module.

* bpo-29240: PEP 540: Add a new UTF-8 Mode (#855)Victor Stinner2017-12-131-2/+3
| | | | | | | | | | | | | | | | | | | | | | * 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.

| | | | | | | | | | | | | | | | | | | | | | | | str.encode, bytes.decode and bytearray.decode now use an internal API to throw LookupError for known non-text encodings, rather than attempting the encoding or decoding operation and then throwing a TypeError for an unexpected output type. The latter mechanism remains in place for third party non-text encodings. Backported changeset d68df99d7a57.

| | | | | | | | | | | | | | | | | | | | | | | | The codecs themselves were restored in Python 3.2, this completes the restoration by adding back the convenience aliases. These aliases were originally left out due to confusing errors when attempting to use them with the text encoding specific convenience methods. Python 3.4 includes several improvements to those errors, thus permitting the aliases to be restored as well.
