The _update method detected mutable elements by trapping TypeErrors.
Unfortunately, this masked useful TypeErrors raised by the iterable
itself. For cases where it is possible for an iterable to raise
a TypeError, the iterable is pre-converted to a list outside the
try/except so that any TypeErrors propagate through.

(lastmark_restore): New function, implementing algorithm to restore
a state to a given lastmark. In addition to the similar algorithm used
in a few places of SRE_MATCH, restore lastindex when restoring lastmark.
(SRE_MATCH): Replace lastmark inline restoring by lastmark_restore(),
function. Also include it where missing. In SRE_OP_MARK, set lastindex
only if i > lastmark.

angered some God somewhere. After noticing
>>> range(5000000)[slice(96360, None, 439)]
[]
I found that my cute test for the slice being empty failed due to
overflow. Fixed, and added simple test (not the above!).
bug #596434. (Alas, I don't think this completely covers that bug.)
Remove 'wrapper' argument from BaseTestCase.check_split() -- it's not
actually needed.
Since properties are supported here, is possible that
instance_getattr2() raises an exception. Fix all code that made this
assumption.
Backport candidate.
classes was called with three arguments. This makes no sense, there's
no way to pass in the "modulo" 3rd argument as for __pow__, and
classic classes don't do this. [SF bug 620179]
I don't want to backport this to 2.2.2, because it could break
existing code that has developed a work-around. Code in 2.2.2 that
wants to use __ipow__ and wants to be forward compatible with 2.3
should be written like this:
def __ipow__(self, exponent, modulo=None):
...
initializing GNU readline, setlocale(LC_CTYPE, "") is called, which
changes the <ctype.h> macros to use the "default" locale (which isn't
the *initial* locale -- the initial locale is the "C" locale in which
only ASCII characters are printable). When the default locale is e.g.
Latin-1, the repr() of string objects can include 8-bit characters
with the high bit set; I believe this is due to the recent
PRINT_MULTIBYTE_STRING changes to stringobject.c. This in turn screws
up test_pyexpat and test_rotor, which depend on the repr() of 8-bit
strings with high bit characters.
The solution (for now) is to force the LC_CTYPE locale to "C" after
importing rlcompleter. This is the locale required by the test suite
anyway.
ths "should be" skipped depends on os.path.supports_unicode_filenames,
not really on the platform. Fiddled the expected-skip constructor
appropriately.
list(xrange(sys.maxint / 4))
test. Changed 4 to 2.
The belief is that this test intended to trigger a bit of code in
listobject.c's NRESIZE macro that's looking for arithmetic overflow. As
written, it doesn't achieve that, though, and leaves it up to the platform
realloc() as to whether it wants to allocate 2 gigabytes. Some platforms
say "sure!", although they don't appear to mean it, and disaster ensues.
Changing 4 to 2 (just barely) manages to trigger the arithmetic overflow
test instead, leaving the platform realloc() out of it.
I'll backport this to the 2.2 branch next.
sys.getwindowsversion() on Windows (new enahanced Tim-proof <wink>
version), and fix test_pep277.py in a few minor ways.
Including doc and NEWS entries.
patch #617312, both on the trunk and the 22-maint branch.
Also added a test case, and ported the test_trace I wrote for HEAD
to 2.2.2 (with all those horrible extra 'line' events ;-).
