Passing the wrong types to codecs can currently lead to rather confusing exceptions, like:
====================
>>> b"ZXhhbXBsZQ==\n".decode("base64_codec")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib64/python3.2/encodings/base64_codec.py", line 20, in base64_decode
return (base64.decodebytes(input), len(input))
File "/usr/lib64/python3.2/base64.py", line 359, in decodebytes
raise TypeError("expected bytes, not %s" % s.__class__.__name__)
TypeError: expected bytes, not memoryview
====================
>>> codecs.decode("example", "utf8")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib64/python3.2/encodings/utf_8.py", line 16, in decode
return codecs.utf_8_decode(input, errors, True)
TypeError: 'str' does not support the buffer interface
====================
This situation could be improved by having the affected APIs use the exception chaining system to wrap these errors in a more informative exception that also display information on the codec involved. Note that UnicodeEncodeError and UnicodeDecodeError are not appropriate, as those are specific to text encoding operations, while these new wrappers will apply to arbitrary codecs, regardless of whether or not they use the unicode error handlers. Furthermore, for backwards compatibility with existing exception handling, it is probably necessary to limit ourselves to specific exception types and ensure that the wrapper exceptions are subclasses of those types.
These new wrappers would have __cause__ set to the exception raised by the codec, but emit a message more along the lines of the following:
==============
codecs.DecodeTypeError: encoding='utf8', details="TypeError: 'str' does not support the buffer interface"
==============
Wrapping TypeError and ValueError should cover most cases, which would mean four new exception types in the codecs module:
Raised by codecs.decode, bytes.decode and bytearray.decode:
* codecs.DecodeTypeError
* codecs.DecodeValueError
Raised by codecs.encode, str.encode:
* codecs.EncodeTypeError
* codecs.EncodeValueError
Instances of UnicodeError wouldn't be wrapped, since they already contain codec information.

There may also be some specific improvement to be made to str.encode, bytes.decode and bytearray.decode in relation to the additional type checks they do to enforce the appropriate input and output types (see the bizarre "expected bytes, not memoryview" example)

I tracked down the proximate cause of the weird exception in the bytes.decode case: the base64 module only accepts bytes and bytearray objects, instead of using memoryview to accept anything that supports the buffer API and provides a C-contiguous 8-bit view of the underlying data. Raised as issue 17839.

Here's an example of the specific type errors raised by additional checks in the text-encoding specific methods. I believe the main improvement needed here is to mention the encoding name in the exception message:
"example".encode("rot_13")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: encoder did not return a bytes object (type=str)

Ezio pointed out on IRC that the extra type checks in str.encode, bytes.decode and bytearray.decode should reference the appopriate codecs module function in addition to the codec in use.
So if str.encode produces something other than bytes, it should reference codecs.encode, while the binary decoding methods should mention codecs.decode if they produce something other than str.

The attached patch changes the error message of str.encode/bytes.decode when the codec returns the wrong type:
>>> import codecs
>>> 'example'.encode('rot_13')
TypeError: encoder returned 'str' instead of 'bytes', use codecs.decode for str->str conversions
>>> codecs.encode('example', 'rot_13')
'rknzcyr'
>>>
>>> b'000102'.decode('hex_codec')
TypeError: decoder returned 'bytes' instead of 'str', use codecs.encode for bytes->bytes conversions
>>> codecs.decode(b'000102', 'hex_codec')
b'\x00\x01\x02'
This only solves part of the problem though, because individual codecs might raise other errors if the input type is wrong:
>>> 'example'.encode('hex_codec')
Traceback (most recent call last):
File "/home/wolf/dev/py/py3k/Lib/encodings/hex_codec.py", line 16, in hex_encode
return (binascii.b2a_hex(input), len(input))

To summarize:
* str.encode does only str->bytes;
* bytes.decode does only bytes-> str;
* codecs.encode/decode do obj->obj;
The things that could go wrong are:
1) the input type is wrong (i.e. the codec doesn't accept the type of the input);
2) the input value is invalid;
3) for str.encode/bytes.decode only, the output type is wrong (i.e. the codec returned a non-bytes/non-str object);
My patch only covers 3. The four new exceptions suggested by Nick in msg187704 would cover the first 2 cases.
For str.encode/bytes.decode, if we knew the input type accepted by the codec we could also provide a better error message (e.g. "codecs accepts '...', not '...'; use ... instead"), but we don't.

The attached proof of concept catches Type/ValueError in str.encode and raises another exception with a better message:
>>> 'example'.encode('hex_codec')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: invalid input type for hex_codec codec ('str' does not support the buffer interface)
(note: the patch doesn't handle the exception chaining yet and probably leaks.)
If Nick proposal in msg187704 is accepted, this should become a codecs.EncodeTypeError. The same should then be done for bytes.decode and for codecs.encode/decode.

Updated patch. The results of this suggests to me that the input wrappers are likely infeasible at this point in time, but improving the errors for the wrong *output* type is entirely feasible. Since the main conversion we need to prompt is things like "binary_object.decode(binary_codec)" -> "codecs.decode(binary_object, binary_codec)", I suggest we limit the scope of this issue to that part of the problem.
>>> import codecs
>>> codecs.encode(b"hello", "bz2_codec").decode("bz2_codec")
Traceback (most recent call last):

TypeError: 'bz2_codec' decoder returned 'bytes' instead of 'str'; use codecs.decode to decode to arbitrary types

The other thing is that this patch doesn't wrap AttributeError. I'm OK with that, since I believe the only codec in the standard library that currently throws that for a bad input type is rot_13.

-1 for the same reasons I keep repeating over and over and over again :-)
The codec system was designed to work obj->obj. Python 3 limits the types
for the bytes/str helper methods, but that limitation does not extend
to the codec design.
+1 on having better error messages. In the long run, we should add
supported input/output type information to codecs, so that error
reporting and codec introspection becomes easier.

I think I figured out a better way to structure this that avoids the need for the output flag and is more easily expanded to whitelist additional exception types as safe to wrap.
I'll try to come up with a new patch tonight.

New and improved implementation attached that extracts the exception chaining to a helper functions and calls it only when it is the call in to the codecs machinery that failed (eliminating the need for the output flag, and covering decoding as well as encoding).
TypeError, AttributeError and ValueError are all wrapped with chained exceptions that mention the codec that failed.
(Annoyingly, bz2_codec throws OSError instead of ValueError for bad input data, but wrapping OSError safely is a pain due to the extra state potentially carried on instances. So letting it escape unwrapped is the simpler and more conservative option at this point)
>>> import codecs
>>> codecs.encode(b"hello", "bz2_codec").decode("bz2_codec")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: 'bz2_codec' decoder returned 'bytes' instead of 'str'; use codecs.decode to decode to arbitrary types

The above exception was the direct cause of the following exception:

Checking the other binary<->binary and str<->str codecs with input type and value restrictions:
- they all throw TypeError and get wrapped appropriately when asked to encode str input (rot_13 throws the output type error)
- rot_13 throws an appropriately wrapped AttributeError when asked to decode bytes or bytearray object
For bad value input, "uu_codec" is the only one that throws a normal ValueError, I couldn't figure out a way to get "quopri_codec" to complain about the input value and the others throw a module specific error:
binascii (base64_codec, hex_codec) throws binascii.Error (a custom ValueError subclass)
zlib (zlib_codec) throws zlib.error (inherits directly from Exception)
As with the OSError that escapes from bz2_codec, I think the simplest and most conservative option is to not worry about those at this point.

Updated patch adds systematic tests for the new error handling to test_codecs.TransformTests
I also moved the codecs changes up to a "Codec handling improvements" section.
My rationale for doing that is that this is actually a pretty significant usability enhancement and Python 3 codec model clarification for heavy users of binary codecs coming from Python 2, and because I also plan to follow up on this issue by bringing back the shorthand aliases for these codecs that were removed in issue 10807 (thus closing issue 7475).
If issue 15216 gets finished (changing stream encodings after creation) that would also be a substantial enhancement worth mentioning here.

Updated patch (v5) with a more robust chaining mechanism provided as a private "_PyErr_TrySetFromCause" API. This version eliminates the previous whitelist in favour of checking directly for the ability to replace the exception with another instance of the same type without losing information.
This version also has more direct tests of the exception wrapping behaviour as a dedicated test class.
If I don't hear any objections in the next couple of days, I plan to commit this version.

This doesn't look right:

+ );
BTW: Why don't we make that API a public one ? It could be useful
in C extensions as well.
In the error messages, I'd use "codecs.encode()" and "codecs.decode()"
(ie. with parens) instead of "codecs.encode" and "codecs.decode".

The signature? That API doesn't currently let you change the exception
type, only the message (since the codecs machinery doesn't need to
change the exception type, and changing the exception type is fraught
with peril from a backwards compatibility point of view).

Because I'm not sure it's a good idea in general and hence am wary of
promoting it too much at this point in time (especially given the
severe limitations of what it can currently wrap). I'm convinced it's
worth it in this particular case (since being told the codec involved
directly makes the meaning of codec errors much clearer and even with
the limitations it can still wrap most errors from standard library
codecs), and the implementation *has* to be in exceptions.c since it
pokes around comparing the exception details to the internals of
BaseException to figure out if it can safely wrap the exception or
not.
Issue 18861 also makes me wonder if there's an underlying structural
problem in the way exception chaining currently works that could be
better solved by making it possible to annotate traceback frames while
unwinding the stack, which also makes me disinclined to add to the
public C API in this area before 3.5.

After sending my previous reply, I realised you may have been
referring to the comment. I copied that from the PyErr_Format
signature. According to
http://docs.python.org/dev/c-api/unicode.html#PyUnicode_FromFormat,
the format string still has to be ASCII-encoded, and if that's no
longer true, it's a separate bug from this one that will require a
docs fix as well.

Sorry about the false warning. After looking at those lines
again, I realized that the "..." is the argument ellipsis,
not some omitted code. At first this look like a function
definition to me :-)

Also note that it's not clear whether the "ASCII"
refers to the format string or the resulting formatted string.
For the format string, ASCII would probably be fine, but
for the formatted string, UTF-8 should be allowed, since it's
not uncommon to add e.g. parameter strings that caused the
error to the error string.
That's a separate ticket, though.

Patch for the final version that I'm about to commit.
- I realised the exception chaining would only trigger for the encode() and decode() methods, when it was equally applicable to the codecs.encode() and codecs.decode() functions, so I updated the test cases and moved it accordingly.
- reworded the What's New text to better clarify the historical confusion around the nature of the codecs module that these changes are intended to rectify (since the intent is clear from the existence of codecs.encode and codecs.decode and their coverage in the test suite since Python 2.4).
