[issue1367711] Remove usage of UserDict from os.py
Andrew Dalke added the comment:
Ahh, so the bug here that the environ dict should use neither UserDict nor
dict, it should implement the core {get,set,del}item and keys and use
DictMixin.
Martin mentioned that the patch doesn't support setdefault. He didn't note
though that the current code also doesn't support the dictionary interface
consistently. This shows a problem with popitem.

[issue923643] long - byte-string conversion
Antoine Pitrou added the comment: Unless I'm mistaken, the patch provides only half of the solution: the stringToLong part, but not longToString. I agree this feature is interesting, not for optimization but becomes it avoids using clunky ways (long - hex - bin) to implement something simple. However, perhaps making it part of either the binascii or the struct module would allow more formatting choices (e.g. big-endian or little-endian, fixed-length or not). For example in cryptography you would want a byte string of a fixed size even if your 512-bit number happens to have its 8 most significant bits set to zero. -- nosy: +pitrou Tracker [EMAIL PROTECTED] http://bugs.python.org/issue923643 ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue1682] Move Demo/classes/Rat.py to Lib/rational.py and fix it up.
Jeffrey Yasskin added the comment:
_binary_float_to_ratio: Oops, fixed.
Rational() now equals 0, but I'd like to postpone Rational('3/2') until
there's a demonstrated need. I don't think it's as common a use as
int('3'), and there's more than one possible format, so some real world
experience will help (that is, quite possibly not in 2.6/3.0). I'm also
postponing Rational(instance_of_numbers_Rational).
+/-inf and nan are gone, and hash is fixed, at least until the next bug.
:) Good idea about using tuple.
Parentheses in str() help with reading things like
%s**2%Rational(3,2), which would otherwise format as 3/2**2. I don't
feel strongly about this.
Equality and the comparisons now work for complex, but their
implementations make me uncomfortable. In particular, two instances of
different Real types may compare unequal to the nearest float, but equal
to each other and have similar but inconsistent problems with =. I can
trade off between false ==s and false !=s, but I don't see a way to make
everything correct. We could do better by making the intermediate
representation Rational instead of float, but comparisons are inherently
doomed to run up against the fact that equality is uncomputable on the
computable reals, so it's probably not worthwhile to spend too much time
on this.
I've added a test that float(Rational(long('2'*400+'7'),
long('3'*400+'1'))) returns 2.0/3. This works without any explicit
scaling on my part because long.__truediv__ already handles it. If
there's something else I'm doing wrong around here, I'd appreciate a
failing test case.
The open issues I know of are:
* Is it a good idea to have both numbers.Rational and
rational.Rational? Should this class have a different name?
* trim and approximate: Let's postpone them to a separate patch (I do
think at least one is worth including in 2.6+3.0). So that you don't
waste time on them, we already have implementations in the sandbox and
(probably) a good-enough explanation at
http://en.wikipedia.org/wiki/Continued_fraction#Best_rational_approximations.
Thanks for the offer to help out with them. :)
* Should Rational.from_float() exist and with the current name? If
there's any disagreement, I propose to rename it to
Rational._from_float() to discourage use until there's more consensus.
* Rational.from_decimal(): punted to a future patch. I favor this for
2.6+3.0.
* Rational('3/2') (see above)
I think this is close enough to correct to submit and fix up the
remaining problems in subsequent patches. If you agree, I'll do so.

[issue1700288] Armin's method cache optimization updated for Python 2.6
Amaury Forgeot d'Arc added the comment:
After some debug work, I found an explanation:
- The attribute name is the name of a type slot. So it becomes cached
during the type construction.
- in function ctypes/_ctypes.c::StructUnionType_new(), the type's
__dict__ is replaced by a stgdict.
- this stgdict is then modified with PyDict_ functions, without any
call to _PyType_Lookup()
- the method cache becomes out of sync == boom.
I have come with a patch which corrects the problem, and all ctypes
tests pass:

I think that these changes are sensible: The first one deal with the
type's attribute instead of updating its __dict__, and the second
properly delegates tp_setattro to the base class ('type' in this case).

Though i don't think we have many (any?) of that type of regression test right now. Such a test would need to setup a test user site package, os.system another instance python with and without -s to confirm if it saw the test site package that was just created or not followed by cleaning it all up. -- nosy: +gregory.p.smith __ Tracker [EMAIL PROTECTED] http://bugs.python.org/issue1799 __ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue1682] Move Demo/classes/Rat.py to Lib/rational.py and fix it up.
Mark Dickinson added the comment: The latest version of rational.py looks good to me---nice work! (I haven't looked properly at numbers.py or test_rational.py, yet. I do plan to, eventually.) I do think it's important to be able to create Rational instances from strings: e.g., for easy reading from and writing to files. But maybe I'm alone in this opinion. You say there's more than one possible format---what other formats were you considering? And since you pointed it out, I think Rational(Rational(a, b)) should work too. There's also the not-entirely-insignificant matter of documentation :) Other than that, I don't see why this shouldn't go in. Other comments: I have a weak preference for no parentheses on the str() of a Rational, but it's no big deal either way. I agree that equality and comparisons are messy. This seems almost inevitable: one obvious cause is that the existing int - float comparisons already break the `numeric tower' model (push both operands to the highest common type before operating). So I'm not sure there can be an easy and elegant solution here :( I like the name Rational for this class. Maybe change the name of numbers.Rational instead? Postponing trim, approximate, from_decimal sounds fine to me. Finally: the very first line of rational.py is, I think, no longer accurate. Please add your name so everyone knows who to blame/credit/assign bug reports to :) __ Tracker [EMAIL PROTECTED] http://bugs.python.org/issue1682 __ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue1771] Remove cmp parameter to list.sort() and builtin.sorted()

[issue1682] Move Demo/classes/Rat.py to Lib/rational.py and fix it up.
Mark Dickinson added the comment:
Just had a quick look at numbers.py. Only two comments:
1. I think there's a typo in the docstring for Inexact: one of those == should
be a !=
2. Not that it really matters now, but note that at least for Decimal, x-y is
not the same
as x+(-y) (I'm looking at Complex.__sub__), and +x is not a no-op (Real.real,
Real.conjugate). In both cases signs of zeros can be problematic:
x = Decimal('-0')
y = Decimal('0')
x-y
Decimal(-0)
x+(-y)
Decimal(0)
x
Decimal(-0)
+x
Decimal(0)
Of course the first point wouldn't matter anyway since Decimal already
implements __sub__;
the second means that if Decimal were to join Real, something would need to be
done to
avoid Decimal(-0).real becoming Decimal(0).

[issue1816] sys.cmd_flags patch

[issue1820] Enhance Object/structseq.c to match namedtuple and tuple api
New submission from Christian Heimes: Raymond Hettinger wrote: Here's a couple more if you want to proceed down that path: 1. Have structseq subclass from PyTupleObject so that isinstance(s, tuple) returns True. This makes the object usable whenever tuples are needed. 2. Add _fields, _asdict, and _replace to match the API in collections.namedtuple(). The _fields tuple should only include the visible positional fields while _asdict() and _replace() should include all of the fields whether visible or accessible only by attribute access. 3. Change the constructor to accept keyword args so that eval(repr(s)) == s works. NOTE: I've marked the task as easy but it's not a task for a total newbie. It's a feasible yet challenging task for somebody who likes to get into CPython core programming.
