[issue1688] Incorrectly displayed non ascii characters in prompt using input() - Python 3.0a2
Martin v. Löwis added the comment: Isn't it enough to encode the prompt with the console encoding, instead of letting the default utf-8 conversion? This patch corrects the issue on Windows: Sounds right. Technically, you should be using the stdout encoding, but I don't think it should ever differ from the stdin_encoding. __ Tracker [EMAIL PROTECTED] http://bugs.python.org/issue1688 __ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue1780] Decimal constructor accepts newline terminated strings
Facundo Batista added the comment: Mark Dickinson: The other option that maintains full compliance with the specification is to do what we like with Decimal.__new__ (e.g. allowing leading and trailing whitespace), but make sure that there's a fully conforming to-number elsewhere in the Decimal module. I'm +1 to be more permissive in the __new__ regarding spaces, tabs, and even newlines. I'm -0 to add an special module that does not allow this. I don't see the value of it more than be compliant to the standard in that particular sentence. Guido van Rossum: I'd say that accepting a trailing \n is a bug that should be fixed. I think that ideally we'd be allowed to specify whitespace around the value. I am always annoyed at programs that require Do you want to be able to do Decimal(3 ) but not Decimal(3\n)? That confused me, I always read whitespace here as all these characters, as in the string module: string.whitespace '\t\n\x0b\x0c\r ' To be more practical about my point, I'm +1 to do a .strip() in __new__ before parsing the number. __ Tracker [EMAIL PROTECTED] http://bugs.python.org/issue1780 __ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue1792] o(n*n) marshal.dumps performance for largish objects with patch
New submission from Aaron Watters: Much to my surprise I found that one of my applications seemed to be running slow as a result of marshal.dumps. I think the culprit is the w_more(...) function, which grows the marshal buffer in 1k units. This means that a marshal of size 100k will have 100 reallocations and string copies. Other parts of Python (and java etc) have a proportional reallocation strategy which reallocates a new size based on the existing size. This mean a 100k marshal requires just 5 or so reallocations and string copies (n log n versus n**2 asymptotic performance). I humbly submit the following patch (based on python 2.6a0 source). I think it is a strict improvement on the existing code, but I've been wrong before (twice ;)). -- Aaron Watters -- components: Interpreter Core files: marshal.diff messages: 59710 nosy: aaron_watters severity: normal status: open title: o(n*n) marshal.dumps performance for largish objects with patch type: resource usage versions: Python 2.6 Added file: http://bugs.python.org/file9122/marshal.diff __ Tracker [EMAIL PROTECTED] http://bugs.python.org/issue1792 __ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Raymond, do you want me to add Decimal.__init__(Rational) in this patch or another issue/thread? I don't understand the comment about scaling down long integers. It's already the case that float(Rational(10**23, 10**24 + 7))==0.1. Mark, I agree that .trim() and/or .approximate() (which I think is the same as Haskell's approxRational) would be really useful. Do you have particular reasons to pick .trim? Are those the best names for the concepts? I'd also really like to be able to link from their docstrings to a proof that their implementations are correct. Does anyone know of one? Finally, Decimal(2.5) != Rational(5, 2) because Decimal(2.5) != 2.5 (so it'd make equality even more intransitive) and hash(Decimal(2.5)) != hash(2.5) so we couldn't follow the rule about equal objects implying equal hash codes, which is probably more serious. I don't have a principled explanation for Decimal's behavior, but given that it's fixed, I think the behavior of non-integral Rationals is determined too. On the other hand, I currently have a bug where Rational(3,1) != Decimal(3) where the hash code could be consistent. I'll fix that by the next patch. __ 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

Raymond, do you want me to add Decimal.__init__(Rational)

How about focusing on the rational module and when you've done, I'll
adapt the Decimal constructor to accept a rational input.
I don't understand the comment about scaling down long integers.
My understanding is that you're going to let numerators and denominators
grow arbitrarily large. When they get over several hundred digits each,
you will have to scale the down before converting to a float. For
example when numerator=long('2'*400+'7') and
denominator=long('3'*400+'1'), the long--float conversion will
overflow, so it is necessary to first scale-down the two before
computing the ratio: scale=325;
float_ratio=float(numeratorscale)/float(denominatorscale)

Thomas Heller added the comment: The cross-platform function is ctypes.util.find_library, which is currently not very useful on Windows. This patch changes it so that, on Windows, find_library(c) or find_library(m) finds the MS C runtime lib which exposes functions the are typically in libc and libm. The runtime lib in Windows is special anyway; the 'open' function, for example, is exported as '_open'. However, the easiest way on Linux (don't know about other platforms) to load the C runtime lib is to use ctypes.CDLL(None), which translates to dlopen(NULL) in C.

[issue1794] Hot keys must work in any keyboard layout
Christian Heimes added the comment: I *think* Nashev is talking about assigning hot keys by scan code rather than by character code. E.g. on a German keyboard the 'z' and 'y' are switched and the 'z' key is left to the 't' key. If a program assigns a hot key to 'z' by character code than the user has to press the 'z' key which is a different key on the German keyboard. However if a hot key is assigned by scan code (not sure if it's the right term) than the hot key is still assigned the physical key in the lower left corner. -- nosy: +tiran __ Tracker [EMAIL PROTECTED] http://bugs.python.org/issue1794 __ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue1794] Hot keys must work in any keyboard layout
Nashev added the comment:
WOW, so active discussion!
OS - Windows Mac OS X, both
Programs - most system and many others.
Keyboard layouts - I mean mostly non latin (see
http://en.wikipedia.org/wiki/Keyboard_layout#Keyboard_layouts_for_non-Roman_alphabetic_scripts)
In case of russian keyboard layout i have in place of latin char 'x'
russian letter 'ч', and want to call Cut command by pressing this
hot key when keyboard really sent to application some like Ctrl+Ч too
In Windows we have messages WM_KeyDown and WM_KeyUp that send always key
index, stored as constants (defined in windows.h or messages.h) like
wk_return, wk_F1, etc. For letter keys, messages come with codes that
always equal to index of similar uppercase latin chars. for example,
first key code in middle row equal ord ('A') = 65. And in context of
russian layout this code translated to Cyrillic letter Ф and sent to
window with next message wm_char. Hot key handling based on WM_KeyDown,
nor WM_Char
P.S.: Samples of localized showing of the hot keys in menu based on
interface language or current keyboard layout I can't find right now,
but i remember that I have this experience. This is feature not
necessary, because reading some like Ctrl+Ч near menu Cut is really
frustrating.

[issue1798] Add ctypes calling convention that allows safe access of errno
New submission from Thomas Heller: This patch adds new calling conventions to ctypes foreign functions by passing 'errno=True' or 'GetLastError=True' to the CDLL or WinDLL constructor. If CDLL(..., errno=True) or WinDLL(..., errno=True) is used, the function objects available in the CDLL or WinDLL instance will set the C global errno to zero before the actual call, and attach the C global errno value after the call as 'errno' attribute to the function object. This attribute is stored in thread-local storage. Similarly, if CDLL(..., GetLastError=True) or WinDLL(..., GetLastError=True) is used, the win32 api function 'SetLastError(0)' is used to reset the windows last error code before the actual call, and the value returned by 'GetLastError()' is attached as 'LastError' attribute to the function object, in thread local storage. Of course this only occurs on Windows. The LastError and errno attributes are readonly from Python code, accessing them before a foreign function call has occurred in the current thread raises a ValueError. -- assignee: theller components: Extension Modules files: ctypes-errno.patch keywords: patch messages: 59748 nosy: theller severity: normal status: open title: Add ctypes calling convention that allows safe access of errno type: rfe versions: Python 2.6 Added file: http://bugs.python.org/file9130/ctypes-errno.patch __ Tracker [EMAIL PROTECTED] http://bugs.python.org/issue1798 __ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Here is an example: Python 2.5.1 (r251:54863, Apr 18 2007, 08:51:08) [MSC v.1310 32 bit (Intel)] on win32 Type help, copyright, credits or license for more information. from ctypes import * A = c_int * 1 A class '__main__.c_long_Array_1' Foo = CFUNCTYPE(None, A) def py_foo(a): ... print a ... print a[0] ... foo = Foo(py_foo) foo(A(42)) __main__.c_long_Array_1 object at 0x00B54440 11879448 It works correctly when the callback is declared with a pointer argument instead: A = c_int * 1 Foo = CFUNCTYPE(None, POINTER(c_int)) def py_foo(p): ... print p ... print p[0] ... foo = Foo(py_foo) foo(A(42)) ctypes.LP_c_long object at 0x00B54440 42 -- components: Library (Lib), Windows messages: 59759 nosy: kermode severity: normal status: open title: ctypes callback fails when called in Python with array argument type: behavior versions: Python 2.5 __ Tracker [EMAIL PROTECTED] http://bugs.python.org/issue1800 __ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue1810] Partial AST compile() patch
New submission from Thomas Lee: This patch against HEAD provides the inverse operations to all the ast2obj_* functions in Python/Python-ast.c: effectively, this allows conversion to from a PyObject representation of a Python AST.

[issue1682] Move Demo/classes/Rat.py to Lib/rational.py and fix it up.
Mark Dickinson added the comment:
More comments, questions, and suggestions on the latest patch:
1. In _binary_float_to_ratio, the indentation needs adjusting. Also 'top = 0L'
could be replaced with 'top =
0', unless you need this code to work with Python 2.3 and earlier, in which
case top needs to be a long so
that behaves correctly. Otherwise, this looks good.
2. Rational() should work, and it should be possible to initialize from a
string. I'd suggest that
Rational(' 1729 '), Rational('-3/4') and (' +7/18 \n') should be
acceptable: i.e. leading and trailing
whitespace, and an optional - or + sign should be permitted. But space between
the optional sign and the
numerator, or on either side of the / sign, should be disallowed. Not sure
whether the numerator and
denominator should be allowed to have leading zeros or not---probably yes, for
consistency with int().
3. I don't think representing +/-inf and nan as Rationals (1/0, -1/0, 0/0) is a
good idea---special values
should be kept out of the Rational type, else it won't be an implementation of
the Rationals any more---it'll
be something else.
4. hash(n) doesn't agree with hash(Rational(n)) for large integers (I think you
already mentioned this
above).
5. Equality still doesn't work for complex numbers:
from rational import *
Rational(10**23) == complex(10**23) # expect False here
True
Rational(10**23) == float(10**23)
False
float(10**23) == complex(10**23)
True
6. Why the parentheses around the str() of a Rational?
7. How about having hash of a Rational (in the case that it's not equal to an
integer or a float) be
given by hash((self.numerator, self.denominator))? That is, let the tuple hash
take care of avoiding lots of
hash collisions.

[issue1682] Move Demo/classes/Rat.py to Lib/rational.py and fix it up.
Mark Dickinson added the comment: About .trim and .approximate: it sounds like these are different, but quite closely related, methods: one takes a positive integer and returns the best approximation with denominator bounded by that integer; the other returns the 'smallest' rational in a given interval centered at the original rational. I guess we probably don't need both of these, but I can't give any good reason for preferring one over the other. I don't have anything to offer about names, either. I can try to find out whether the algorithms are published anywhere on the web---certainly, neither algorithm should be particularly hard to implement and prove the correctness of; they both essentially rely on computing the continued fraction development of the given rational. Almost any not-too-basic elementary number theory text should contain proofs of the relevant results about continued fractions. Am willing to help out with implementing either of these, if that's at all useful. __ 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
