Issue #7673: Fix security vulnerability (CVE-2010-2089) in the audioop module,
ensure that the input string length is a multiple of the frame size
........
reality it's simply an implementation detail for CPython. This point is now
clearly documented in both the docs for dis and the glossary.
Closes issue #7829. Thanks to Terry Reedy for some initial suggestions on
wording.
1) #8271: when a byte sequence is invalid, only the start byte and all the
valid continuation bytes are now replaced by U+FFFD, instead of replacing
the number of bytes specified by the start byte.
See http://www.unicode.org/versions/Unicode5.2.0/ch03.pdf (pages 94-95);
2) 5- and 6-bytes-long UTF-8 sequences are now considered invalid (no changes
in behavior);
3) Change the error messages "unexpected code byte" to "invalid start byte"
and "invalid data" to "invalid continuation byte";
4) Add an extensive set of tests in test_unicode;
5) Fix test_codeccallbacks because it was failing after this change.
SourceLoader is a simplification of both PyLoader and PyPycLoader. If one only
wants to use source, then they need to only implement get_data and
get_filename. To also use bytecode -- sourceless loading is not supported --
then two abstract methods -- path_mtime and set_data -- need to be implemented.
Compared to PyLoader and PyPycLoader, there are less abstract methods
introduced and bytecode files become an optimization controlled by the ABC and
hidden from the user (this need came about as PEP 3147 showed that not treating
bytecode as an optimization can cause problems for compatibility).
PyLoader is deprecated in favor of SourceLoader. To be compatible from Python
3.1 onwards, a subclass need only use simple methods for source_path and
is_package. Otherwise conditional subclassing based on whether Python 3.1 or
Python 3.2 is being is the only change. The documentation and docstring for
PyLoader explain what is exactly needed.
PyPycLoader is deprecated also in favor of SourceLoader. Because PEP 3147
shifted bytecode path details so much, there is no foolproof way to provide
backwards-compatibility with SourceLoader. Because of this the class is simply
deprecated and users should move to SourceLoader (and optionally PyLoader for
Python 3.1). This does lead to a loss of support for sourceless loading
unfortunately.
At some point before Python 3.2 is released, SourceLoader will be moved over to
importlib._bootstrap so that the core code of importlib relies on the new code
instead of the old PyPycLoader code. This commit is being done now so that
there is no issue in having the API in Python 3.1a1.
from the fact that OPT contains -Wall be default. This is annoying when
compilers like clang have thorough debugging information about things that
Python does extensively (e.g. -Wunused-value for unused return values caused by
a macro use).

dealing with unary minus applied to a constant. The removed code was
mutating the ST, causing a second compilation to fail. (The peephole
optimizer already takes care of optimizing this case, so there's no
lost optimization opportunity here.)

#8720: fix inspect regression by teaching getsourcefile about linecache.
The fix for issue 4050 caused a regression: before that fix, source
lines in the linecache would eventually be found by inspect. After the
fix inspect reports an error earlier, and the source isn't found.
The fix for the fix is to have getsourcefile look in the linecache for
the file and return the psuedo-filename if the source is there, just as
it already returns it if there is a PEP 302 loader.

#5610: use \Z not $ so we don't eat extra chars when body part ends with \r\n.
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.
Patch and test by Tony Nelson.
