- io.TextIOWrapper (and hence the open() builtin) now use the
internal codec marking system added for issue #19619
- also tweaked the C code to only look up the encoding once,
rather than multiple times
- the existing output type checks remain in place to deal with
unmarked third party codecs.
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.
Use faster PyUnicode_FromEncodedObject() for bytes/bytearray.decode().
Add new PyCodec_KnownEncoding() API.
Add new PyUnicode_AsDecodedUnicode() and PyUnicode_AsEncodedUnicode() APIs.
Add missing PyUnicode_AsDecodedObject() to unicodeobject.h
Fix punicode codec to also work on memoryviews.
(branch-creation time) up to 43067. 43068 and 43069 contain a little
swapping action between re.py and sre.py, and this mightily confuses svn
merge, so later changes are going in separately.
This merge should break no additional tests.
The last-merged revision is going in a 'last_merge' property on '.' (the
branch directory.) Arbitrarily chosen, really; if there's a BCP for this, I
couldn't find it, but we can easily change it afterwards ;)
