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.
PyUnicode_DecodeCharmap() the accept a unicode string as the mapping
argument which is used as a mapping table.
This code isn't used by any of the codecs yet.
about illegal code points. The codec now supports PEP 293 style error handlers.
(This is a variant of the Nik Haldimann's patch that detects truncated data)
the last character read is "\r" (and size is None, i.e. we're allowed to
call read() multiple times), so that we can return the correct line ending
(this additional character might be a "\n").
If the stream is temporarily exhausted, we might return the wrong line ending
(if the last character read is "\r" and the next one (after the byte stream
provides more data) is "\n", but at least the atcr member ensure that we
get the correct number of lines (i.e. this "\n" will not be treated as
another line ending.)
trying to return a complete line even if a size parameter was given (see
http://www.python.org/sf/1076985). This leads to buffer overflows with long
source lines under Windows if e.g. cp1252 is used as the source encoding.
This patch reverts the behaviour of readline() to something that behaves more
like Python 2.3: If a size parameter is given, read() is called only once.
As a side effect of this, readline() now supports all types of linebreaks
supported by unicode.splitlines().
Note that the tokenizer is still broken and it's possible to provoke segfaults
(see http://www.python.org/sf/1089395).
decoding incomplete input (when the input stream is temporarily exhausted).
codecs.StreamReader now implements buffering, which enables proper
readline support for the UTF-16 decoders. codecs.StreamReader.read()
has a new argument chars which specifies the number of characters to
return. codecs.StreamReader.readline() and codecs.StreamReader.readlines()
have a new argument keepends. Trailing "\n"s will be stripped from the lines
if keepends is false. Added C APIs PyUnicode_DecodeUTF8Stateful and
PyUnicode_DecodeUTF16Stateful.

Also don't use "from test.test_support import ...", but
"from test import test_support" in a few spots.
From SF patch #662807.
of PyString_DecodeEscape(). This prevents a call to
_PyString_Resize() for the empty string, which would
result in a PyErr_BadInternalCall(), because the
empty string has more than one reference.
This closes SF bug http://www.python.org/sf/603937
imports e.g. test_support must do so using an absolute package name
such as "import test.test_support" or "from test import test_support".
This also updates the README in Lib/test, and gets rid of the
duplicate data dirctory in Lib/test/data (replaced by
Lib/email/test/data).
Now Tim and Jack can have at it. :)
