array. Our samplesort special-cases the snot out of this, running about
12x faster than *sort. The experimental mergesort runs it about 8x
faster than *sort without special-casing, but should really do better
than that (when merging runs of different lengths, right now it only
does something clever about finding where the second run begins in
the first and where the first run ends in the second, and that's more
of a temp-memory optimization).
from test.test_support import TestSkipped, run_unittest
to
from test_support import TestSkipped, run_unittest
Otherwise, if the Japanese codecs aren't installed, regrtest doesn't
believe the TestSkipped exception raised by this test matches the
except (ImportError, test_support.TestSkipped), msg:
it's looking for, and reports the skip as a crash failure instead of
as a skipped test.
I suppose this will make it harder to run this test outside of
regrtest, but under the assumption only Barry does that, better to
make it skip cleanly for everyone else.
(i.e. email.test), so move the guts of them here from Lib/test. The
latter directory will retain stubs to run the email.test tests using
Python's standard regression test.
test_email_torture.py is a torture tester which will not run under
Python's test suite because I don't want to commit megs of data to
that project (it will fail cleanly there). When run under the mimelib
project it'll stress test the package with megs of message samples
collected from various locations in the wild.

email/test/data is a copy of Lib/test/data. The fate of the latter is
still undecided.
backwards compatibility, we're silently deprecating get_type(),
get_subtype() and get_main_type(). We may eventually noisily
deprecate these. For now, we'll just fix a bug in the splitting of
the main and subtypes.
get_content_type(), get_content_maintype(), get_content_subtype(): New
methods which replace the above. These /always/ return a content type
string and do not take a failobj, because an email message always at
least has a default content type.
set_default_type(): Someday there may be additional default content
types, so don't hard code an assertion about the value of the ctype
argument.
for the time module, because somehow configure won't define the
symbols HAVE_STRUCT_TM_TM_ZONE, HAVE_TM_ZONE, and HAVE_TZNAME in this
case.
I've got no time to research this further, so I leave it in Jeremy and
Martin's capable hands to find a different solution for True64 (or to
devise a way to get the time tests to succeed while defining
_XOPEN_SOURCE).
C implementation. See SF patch 474274, by Brett Cannon.
(As an experiment, I'm adding a line that #undefs HAVE_STRPTIME,
so that you'll always get the Python version. This is so that it
gets some good exercise. We should eventually delete that line.)

Then I did what was needed, but didn't check it in. Here it is.
listsort. If the former calls itself recursively, they're a waste of
time, since it's called on a random permutation of a random subset of
elements. OTOH, for exactly the same reason, they're an immeasurably
small waste of time (the odds of finding exploitable order in a random
permutation are ~= 0, so the special-case loops looking for order give
up quickly). The point is more for conceptual clarity.
Also changed some "assert comments" into real asserts; when this code
was first written, Python.h didn't supply assert.h.
introduced, list.sort() was rewritten to use only the "< or not <?"
distinction. After rich comparisons were introduced, docompare() was
fiddled to translate a Py_LT Boolean result into the old "-1 for <,
0 for ==, 1 for >" flavor of outcome, and the sorting code was left
alone. This left things more obscure than they should be, and turns
out it also cost measurable cycles.
So: The old CMPERROR novelty is gone. docompare() is renamed to islt(),
and now has the same return conditinos as PyObject_RichCompareBool. The
SETK macro is renamed to ISLT, and is even weirder than before (don't
complain unless you want to maintain the sort code <wink>).
Overall, this yields a 1-2% speedup in the usual (no explicit function
passed to list.sort()) case when sorting arrays of floats (as sortperf.py
does). The boost is higher for arrays of ints.
quoting:
in non-strict mode, messages don't require a blank line at the end
with a missing end-terminator. A single newline is sufficient now.
Handle trailing whitespace at the end of a boundary. Had to switch
from using string.split() to re.split()
Handle whitespace on the end of a parameter list for Content-type.
Handle whitespace on the end of a plain content-type header.
Specifically,
get_type(): Strip the content type string.
_get_params_preserve(): Strip the parameter names and values on both
sides.
_parsebody(): Lots of changes as described above, with some stylistic
changes by Barry (who hopefully didn't screw things up ;).
This gets compilation of posixmodule.c to succeed on Tru64 and does no
harm on Linux. We may need to undefine it on some platforms, but
let's wait and see.
