needs of pickling longs. Backed off to a definition that's much easier
to understand. The pickler will have to work a little harder, but other
uses are more likely to be correct <0.5 wink>.
_PyLong_Sign(): New teensy function to characterize a long, as to <0, ==0,
or >0.
classes have a __reduce__ that returns (self.__class__,
self.__getstate__()). tzinfo.__reduce__() is a bit smarter, calling
__getinitargs__ and __getstate__ if they exist, and falling back to
__dict__ if it exists and isn't empty.
for this iconv() implementation in the init function.
For encoding: use a byteswapped version of the input if
neccessary.
For decoding: byteswap every piece returned by iconv()
if neccessary (but not those pieces returned from the
callback)
Comment out test_sane() in the test script, because
whether this works depends on whether byte swapping
is neccessary or not (an on Py_UNICODE_SIZE)
METH_NOARGS functions are still called with two arguments, one NULL,
so put that back into the function definitions (I didn't know this
until recently).
Make get_history_length() METH_NOARGS.
start for the C implemention of new pickle LONG1 and LONG4 opcodes (the
linear-time way to pickle a long is to call _PyLong_AsByteArray, but
the caller has no idea how big an array to allocate, and correct
calculation is a bit subtle).
compare against "the other" argument, we raise TypeError,
in order to prevent comparison from falling back to the
default (and worse than useless, in this case) comparison
by object address.
That's fine so far as it goes, but leaves no way for
another date/datetime object to make itself comparable
to our objects. For example, it leaves Marc-Andre no way
to teach mxDateTime dates how to compare against Python
dates.
Discussion on Python-Dev raised a number of impractical
ideas, and the simple one implemented here: when we don't
know how to compare against "the other" argument, we raise
TypeError *unless* the other object has a timetuple attr.
In that case, we return NotImplemented instead, and Python
will give the other object a shot at handling the
comparison then.
Note that comparisons of time and timedelta objects still
suffer the original problem, though.
This gives much the same treatment to datetime.fromtimestamp(stamp, tz) as
the last batch of checkins gave to datetime.now(tz): do "the obvious"
thing with the tz argument instead of a senseless thing.
checked in two days agao:
Refactoring of, and new rules for, dt.astimezone(tz).
dt must be aware now, and tz.utcoffset() and tz.dst() must not return None.
The old dt.astimezone(None) no longer works to change an aware datetime
into a naive datetime; use dt.replace(tzinfo=None) instead.
The tzinfo base class now supplies a new fromutc(self, dt) method, and
datetime.astimezone(tz) invokes tz.fromutc(). The default implementation
of fromutc() reproduces the same results as the old astimezone()
implementation, but tzinfo subclasses can override fromutc() if the
default implementation isn't strong enough to get the correct results
in all cases (for example, this may be necessary if a tzinfo subclass
models a time zone whose "standard offset" (wrt UTC) changed in some
year(s), or in some variations of double-daylight time -- the creativity
of time zone politics can't be captured in a single default implementation).
60: Added support for the SkippedEntityHandler, new in Expat 1.95.4.
61: Added support for namespace prefixes, which can be enabled by setting the
"namespace_prefixes" attribute on the parser object.
65: Disable profiling changes for Python 2.0 and 2.1.
66: Update pyexpat to export the Expat 1.95.5 XML_GetFeatureList()
information, and tighten up a type declaration now that Expat is using
an incomplete type rather than a void * for the XML_Parser type.
67: Clarified a comment.
Added support for XML_UseForeignDTD(), new in Expat 1.95.5.
68: Refactor to avoid partial duplication of the code to construct an
ExpatError instance, and actually conform to the API for the exception
instance as well.
69: Remove some spurious trailing whitespace.
Add a special external-entity-ref handler that gets installed once a
handler has raised a Python exception; this can cancel actual parsing
earlier if there's an external entity reference in the input data
after the the Python excpetion has been raised.
70: Untabify APPEND.
71: Backport PyMODINIT_FUNC for 2.2 and earlier.
When daylight time ends, an hour repeats on the local clock (for example,
in US Eastern, the clock jumps from 1:59 back to 1:00 again). Times in
the repeated hour are ambiguous. A tzinfo subclass that wants to play
with astimezone() needs to treat times in the repeated hour as being
standard time. astimezone() previously required that such times be
treated as daylight time. There seems no killer argument either way,
but Guido wants the standard-time version, and it does seem easier the
new way to code both American (local-time based) and European (UTC-based)
switch rules, and the astimezone() implementation is simpler.
underlying DB has already been closed (and thus all of its cursors).
This fixes a potential segfault.
SF pybsddb bug id 667343
bugfix: close the DB object when raising an exception due to an error
during DB.open. This prevents an exception when closing the
environment about not all databases being closed.
SF pybsddb bug id 667340
hoped it would be, but not too bad. A test had to change:
time.__setstate__() can no longer add a non-None tzinfo member to a time
object that didn't already have one, since storage for a tzinfo member
doesn't exist in that case.
into time. This is little more than *exporting* the datetimetz object
under the name "datetime", and similarly for timetz. A good implementation
of this change requires more work, but this is fully functional if you
don't stare too hard at the internals (e.g., right now a type named
"datetime" shows up as a base class of the type named "datetime"). The
docs also need extensive revision, not part of this checkin.
