New submission from STINNER Victor <victor.stin...@haypocalc.com>: codecs module (and codecs.open() function) was added to Python 2.0. codecs.open() creates a StreamReaderWriter object which use two other objects: StreamReader and StreamWriter.
Python 2.6 and 3.0 have a new API: the io module. io.open() creates a TextIOWrapper object which is fully compatible with the file object API (it *is* the (text) file object API :-)). TextIOWrapper supports univeral newline and does better support reading+writing than StreamReaderWriter. TextIOWrapper has a better test suite and is used by default to read and write text files in Python3 (since Python 3.0). The io module has an *optimized* design and the io module was rewritten in C (in Python 2.7 and 3.1). codecs.open() should be deprecated in Python 3.2 and removed in Python 3.3 (not in Python 2.7). Maybe also StreamReader, StreamWriter and StreamReaderWriter: I don't know if any program use directly these classes, but I think that TextIOWrapper can be used instead. ---------- components: Library (Lib), Unicode messages: 106339 nosy: haypo, pitrou priority: normal severity: normal status: open title: Deprecate codecs.open() versions: Python 3.2, Python 3.3 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue8796> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
