Removed the new max_diff argument to assertSequenceEqual. All unittest.TestCase assert methods that use difflib to produce failure messages now truncate overly long messages. New class attribute unittest.TestCase.maxDiff to configure this if necessary. Issue 8351.

unittest TestLoader test discovery filename matching done in a method. This makes it easier to override the matching strategy in subclasses. No behaviour change in actual implementation.

Previously, unexpected results occurred when email was passed, for example,
'utf8' as a charset name, since email would accept it but would *not* use
the 'utf-8' codec for it, even though Python itself recognises that as
an alias for utf-8.  Now Charset checks with codecs for aliases as well
as its own internal table.  Issue 8898 has been opened to change this
further in py3k so that all aliasing is routed through the codecs module.

multiprocessing module.

FreeBSD doesn't have socket.EAI_NODATA.  I rewrote the routine because
there's no easy way to conditionally include a context manager in a
with statement.  As a side benefit, instead of a stack of context
managers there's now only one.

If a body part ended with \r\n, feedparser, using '$' to terminate its
search for the newline, would match on the \r\n, and think that it needed
to strip two characters in order to account for the line end before the
boundary.  That made it chop one too many characters off the end of
the body part.  Using \Z makes the match correct.

the curses module must be linked against ncurses as well. Otherwise it
is not safe to load both the readline and curses modules in an application.

Thanks Thomas Dickey for answering questions about ncurses/ncursesw
and readline!

for extracting symbolic and hard link entries as regular files as a
work-around on platforms that do not support filesystem links.

This stopped working reliably after a change in r74571. I also added
a few tests for this functionality.

expose this bug because it was broken too.

honor the MacOSX SDK when one is specified.

This is needed to be able to build using the 10.4u SDK while running

This is a fixed version of the patch in r80963, I've tested this patch
on OSX and Linux.

Fixes (mysterious, to the end user) UnicodeErrors when using utf-8 as
the charset and unicode as the _text argument.  Also makes the way in
which unicode gets encoded to quoted printable for other charsets more
sane (it only worked by accident previously).  The _payload now is encoded
to the charset.output_charset if it is unicode.

Put docs for RegexObject.search() before RegexObject.match() to mirror re.search() and re.match() order.
