Serhiy Storchaka added the comment: _PyBytesWriter and _PyUnicodeWriter have differen use cases. While _PyUnicodeWriter used primary in formatter where resulting size is rarely known and reallocation in decoders usually caused by widening result, _PyBytesWriter is used only in decoders where we usually can estimate a result size or it's upper bound. Resizing happened only in exceptional cases, when error handler called.
The patch contains a special case for writing only one bytes object. This is very unlikely case. It happened only when an encoded string contains only one illegal character. I think this case is not worth a complication and obfuscation of the code. I think we should drop readonly attribute and a piece of the code (which looks buggy for me anyway). ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue17742> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
