[issue1125] bytes.split shold have same interface as str.split, or different name

[Walter Dörwald]

Walter Dörwald added the comment:

Because it's not clear whether b'\xa0' *is* whitespace or not. Bytes
have no meaning, characters do.

[issue1125] bytes.split shold have same interface as str.split, or different name

[Guido van Rossum]

Guido van Rossum added the comment:

I tend to agree with the author; I've run into this myself. For
whitespace, I propose to use only the following: tab LF FF VT CR space.
These are the whitespace ASCII characters according to isspace() in libc.

(Unicode also treats hex 1C, 1D, 1E and 1F as whitespace; I have no idea
what these mean. In practice I don't think it matters either way.)

[issue1764044] copy 2

[robs pythonid]

robs pythonid
 added the comment:

Thanks for your reaction, I do not really now the answer to your 
question but I added the code to copy files in a directory (to keep it 
simple I removed the recursiveness):

import os
import shutil

sourcedir="d:\\testsourcedir"
targetdir="d:\\testtargetdir"

filelist=os.listdir(sourcedir)  
for afile in filelist:
source=sourcedir + "\\" + afile
if os.path.isfile(source):
time1=os.path.getmtime(source)
print source,time1,
docopy=0
target=targetdir+"\\"+afile
if os.path.isfile(target):
time2=os.path.getmtime(target)
if time1>time2:
docopy=1
else:
docopy=1
if docopy==1:
print " copying"
shutil.copy2(source,target)
else:
print " not copied"

If I run this program twice without changing any file in the source 
directory it should not copy any files anymore (but is does 20% of the 
files it there are 10 files). Now that I have been thinking about 
this a little the problems I see, happen on a Windows Vista Business 
machine, on my XP machine i don't seem to be able to reproduce the 
issues, maybe it is somethin in Vista.

quite frustrating

[issue1129] OpenSSL detection broken for Python 3.0a1

[Stefan Sonnenberg-Carstens]

New submission from Stefan Sonnenberg-Carstens:

In line 618 the comparison must be this:

if (openssl_ver >= 0x00908000):

otherwise there are complaints about not being able to build
the _sha256 and _sha512 modules, even if OpenSSL >= 0.9.8 is installed,
as in my case.

[issue1126] file.fileno and file.isatty() should be implementable by any file like object

[Stefan Sonnenberg-Carstens]

Stefan Sonnenberg-Carstens added the comment:

You are free to do what you want.
Reasons for not implementing fileno and isatty are:
- fileno should be an integer pointing to a real file,
so that low-level functions in libc can handle that. Can you provide
such ? (see http://netbsd.gw.com/cgi-bin/man-cgi?open++NetBSD-current)
- duck-typing / there must be a difference to "real" files in the first
sense

[Georg Brandl]

Georg Brandl added the comment:

I think you misunderstood the setup.py message; from OpenSSL 0.9.8, building
the _sha modules is not needed.  That they are reported as not built is a
bug which has been fixed now in SVN.

Here's a patch that fixes bytes.split and .rsplit.  I'll hold off for a
