i_divmod: New and simpler algorithm. Old one returned gibberish on most
boxes when the numerator was -sys.maxint-1. Oddly enough, it worked in the
release (not debug) build on Windows, because the compiler optimized away
some tricky sign manipulations that were incorrect in this case.
Makes you wonder <wink> ...
Bugfix candidate.
Summary: NAMESPACE support in imaplib.py
Initial Comment:
Support for the IMAP NAMESPACE extension defined in rfc
2342. This is almost a necessity for working with
modern IMAP servers.
and trace functions lazily, which incurs extra argument pushing and checks
in the C overhead for profiling/tracing, create the strings semi-lazily
when the Python code first registers a profile or trace function. This
simplifies the trampoline into the profile/trace functions.
Gave Python linear-time repr() implementations for dicts, lists, strings.
This means, e.g., that repr(range(50000)) is no longer 50x slower than
pprint.pprint() in 2.2 <wink>.
I don't consider this a bugfix candidate, as it's a performance boost.
Added _PyString_Join() to the internal string API. If we want that in the
public API, fine, but then it requires runtime error checks instead of
asserts.
Protect several more uses of constants with #ifdefs; these are necessary on
(at least) SCO OpenServer 5. Fixes a non-SF-submitted bugreport by Michael
Kent.
is allocated than needed (used to allocate 80 bytes of digit space no
matter how small the long input). This also runs faster, at least on 32-
bit boxes.
the new PyLong_{As,From}{Unsigned,}LongLong tests, so the bulk of the
code is in the new #include file testcapi_long.h, which generates
different code depending on how macros are set. This sucks, but I couldn't
think of anything that sucked less.
UNIX headache? If we still maintain dependencies by hand, someone who
knows what they're doing should teach whatever needs it that
_testcapimodule.c includes testcapi_long.h.
Unfortunately, the std-mode bBhHIL codes don't do any range-checking; if
and when some of those get fixed, remove their letters from the
IntTester.BUGGY_RANGE_CHECK string. In the meantime, a msg saying that
range-tests are getting skipped is printed to stdout whenever one is
skipped.
Replaced PyLong_{As,From}{Unsigned,}LongLong guts with calls
to _PyLong_{As,From}ByteArray.
_testcapimodule.c:
Added strong tests of PyLong_{As,From}{Unsigned,}LongLong.
Fixes SF bug #432552 PyLong_AsLongLong() problems.
Possible bugfix candidate, but the fix relies on code added to longobject
to support the new q/Q structmodule format codes.
functions. I intend to replace their guts with calls to the new
_PyLong_{As,From}ByteArray() functions, but AFAICT there's no tests for
them at all now; I also suspect PyLong_AsLongLong() isn't catching all
overflow cases, but without a std test to demonstrate that why should you
believe me <wink>.
Also added a raiseTestError() utility function.
Add a -F option similar to "cvs commit -F <file>".
Add a -t option to allow specifying the prefix to the directory into which
the docs should be unpacked (useful when I start trying out new styles for
the presentation).
This completes the q/Q project.
longobject.c _PyLong_AsByteArray: The original code had a gross bug:
the most-significant Python digit doesn't necessarily have SHIFT
significant bits, and you really need to count how many copies of the sign
bit it has else spurious overflow errors result.
test_struct.py: This now does exhaustive std q/Q testing at, and on both
sides of, all relevant power-of-2 boundaries, both positive and negative.
NEWS: Added brief dict news while I was at it.
_PyLong_FromByteArray
_PyLong_AsByteArray
Untested and probably buggy -- they compile OK, but nothing calls them
yet. Will soon be called by the struct module, to implement x-platform
'q' and 'Q'.
If other people have uses for them, we could move them into the public API.
See longobject.h for usage details.
functions -- these are not available on traditional Mac OS platforms.
Corrected the version annotations for the spawn*() functions and related
constants; these were added in Python 1.6, not 1.5.2.
