diff Python/codecs.c @ 36996:7fa4c29d7030 legacy-trunk
Patch #1436130: codecs.lookup() now returns a CodecInfo object (a subclass
of tuple) that provides incremental decoders and encoders (a way to use
stateful codecs without the stream API). Functions
codecs.getincrementaldecoder() and codecs.getincrementalencoder() have
been added.
