[issue6235] \d missing from effects of re.ASCII flag

[Mitchell Model]

New submission from Mitchell Model :

In the documentation of the re module the ASCII flag is described as
"Make \w, \W, \b, \B, \s and \S perform ASCII-only matching instead of
full Unicode matching." This should also include \d and \D.

[issue6136] Make logging configuration files easier to use

[Vinay Sajip]

Vinay Sajip  added the comment:

"If it was never intended for end users, then perhaps you could rename
this request as "provide an end-user-friendly log configuration format"
(that would live alongside the current one). It's hardly unusual that
users should be able to troubleshoot systems themselves by requesting
more (or different) logging, is it?"

It's unlikely that this would be provided as part of the Python stdlib:
requirements which are truly end-user-friendly are also likely to be
application-specific. When the configuration format was devised I did
seek feedback - but people with strong opinions on the issue told me
they'd prefer to roll their own. I'm fine with that; you can't please
all of the people all of the time and I sadly can't devote much time to
this at the moment.

"For example, log4py's format looked like this:
[my_logger]
LogLevel: Normal
Target: my_filename.log"

Looks fine for logging to files only. Does log4py support the wide range
of output sinks that Python logging does? If not, then the more
complicated logging configuration would seem reasonable as there are
more options in Python logging.

"As for mentions of this issue online, I linked to one such on my
comp.lang.python posting."

I'm not sure which posting you mean - I didn't see any recent postings
by you on c.l.py (I look at it via the corresponding Google group).

Re. the links you posted - Richard Jones' thread came out shortly after
logging was released and was largely about documentation and the need
for casual-use functionality which was subsequently provided by
basicConfig(). The MarkMail thread which you linked to doesn't appear to
raise the same points you did - Steve Hindle's original post of 17 May
2006 mentions only in point 4 about "crufty config file syntax", with no
specifics, and I can only find 3 messages in that thread - 2 by Steve
Hindle and one by Aahz which simply suggests moving the discussion to
c.l.py. I checked the Baypiggies archive on mail.python.org - same thing.

My suggestion would be - if you want to promote a simpler config file
syntax for logging, implement one and upload it on PyPI, and post
announcements on c.l.py and c.l.py.announce. If there is demand for this
functionality, people can easily download your package from PyPI and use
it. After all, logging.config is a separate sub-module and need not be
loaded at all.

[issue6234] cgi.FieldStorage is broken when given POST data

[Evan Fosmark]

New submission from Evan Fosmark :

Right now, it seems impossible to use cgi.FieldStorage in 3.0 if you're

post_data = cgi.FieldStorage(
fp=environ["wsgi.input"],

It gives the following error:

[issue6233] ElementTree (py3k) doesn't properly encode characters that can't be represented in the specified encoding

[Neil Muller]

New submission from Neil Muller :

In py3k, ElementTree no longer correctly converts characters to entities
when they can't be represented in the requested output encoding.

Python 2:

>>> import xml.etree.ElementTree as ET
>>> e = ET.XML("t\xe3t")
>>> ET.tostring(e, 'ascii')
"\ntãt"

Python 3:

>>> import xml.etree.ElementTree as ET
>>> e = ET.XML("t\xe3t")
>>> ET.tostring(e, 'ascii')
.
UnicodeEncodeError: 'ascii' codec can't encode characters in position
1-2: ordinal not in range(128)


It looks like _encode_entity isn't ever called inside ElementTree
anymore - it probably should be called as part of _encode for characters
that can't be represented.

Pretty much anyone can edit a bunch of sections that look like that

As for mentions of this issue online, I linked to one such on my
comp.lang.python posting. It isn't recent, but the points about the
config file still apply as it hasn't substantially changed since then as
far as I can see. 3 different users raise essentially the same point
(and you also contributed to this thread)

[issue2947] subprocess (Replacing popen) - add a warning / hint

[R. David Murray]

R. David Murray  added the comment:

Patch attached that adds an example that shows how to translate return
code handling, loosely based on Helmut's example.  I also turned the
function references in the section titles into links because I think
that would be very useful to someone wanting to do a translation
(provides easy access to the docs for the old functions).  The font size
looks a bit weird in the generated docs, though, so perhaps that is why
this wasn't done originally.  If putting references in section titles is
a no-no let me know and I'll remove them from the patch.

Also included in the patch is a fix for the cross reference link from
the os.spawn section to the 'replacing functions' section of the
subprocess docs.

[issue6136] Make logging configuration files easier to use

[Vinay Sajip]

Vinay Sajip  added the comment:

"Who said anything about not supporting users who want the hierarchy?
I'm talking about making "qualname" optional, not removing it
entirely!"

Ok, I see - sorry for the misunderstanding on my part.

"... these files need to be read and edited by non-coders and they're a
lot scarier (and harder to tweak) than the old ones were. Basically
they're full of abstract technical concepts ("qualname", "handler") and
bits of python code to be eval'ed."

The configuration format is not (and was never) intended for
non-technical end users. Because of the way it works, typos in the
elements which are eval'd can throw exceptions, which is obviously
undesirable. If you want such users to be able to change the logging
configuration, I would advise you implement your own layer which does
not use any technical terminology such as "handler" or "qualname", and
from that layer either update the logging configuration via the logging
API, or write a standard logging config file.

"It's not particularly hard to find people out there raising this if you
google a bit."

Well, I did do a search for "+python +logging +config +problems" which
didn't throw up much (other than this issue). I'd be grateful for some
specific links to recent items which you have found.

[issue6230] ElementTree.Element and cElementTree.Element have slightly different repr

[Neil Muller]

New submission from Neil Muller :

ElementTree and cElementTree give slightly different results for
repr(Element):

>>> import xml.etree.ElementTree as ET
>>> import xml.etree.cElementTree as cET
>>> repr(ET.ElementTree('tag'))
''
>>> repr(cET.ElementTree('tag')
""

The quoting around the tag name is missing from ElementTree.

This inconsistency seems pointless.

Attached patch changes ElementTree to match cElementTree behaviour, and
adds a test.

[issue6228] round() error

[Mark Dickinson]

Mark Dickinson  added the comment:

Thanks for the report.

This is fixed in Python 3.1 (except on a few unusual hardware/OS 
combinations):

Python 3.1rc1+ (py3k:73252, Jun  6 2009, 10:35:36) 
[GCC 4.0.1 (Apple Computer, Inc. build 5367)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> round(697.04157958254996, 10)
697.0415795825

It's a "won't fix" for Python 2.x.  Rounding to 10 decimal places 
involves multiplying by 10**10., rounding to the nearest integer, then 
dividing by 10**10. again;  the problem in this case is that 
multiplication by 10.**10 is inexact, and the error involved in the 
multiplication by 10**10. pushes the value from the 'round down' region 
into the 'round up region':

Python 2.7a0 (trunk:73252, Jun  6 2009, 10:16:08) 
[GCC 4.0.1 (Apple Computer, Inc. build 5367)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> 697.04157958254996 * 10**10
6970415795825.5
[38623 refs]

There's no easy way to fix this, short of using multiple-precision 
arithmetic to do the rounding (which is what Python 3.1 does).


By the way, Python's float can't represent the number

697.04157958254996

exactly (assuming IEEE 754 arithmetic):  the closest it gets is the 
value:

697.041579582549957194714806973934173583984375

but the repr of a float (in Python 3.0 and 2.x) only produces 17 
significant digits, since that's enough to guarantee that the
repr() value evaluates back to the correct float (assuming correct
rounding).

[issue4749] Issue with RotatingFileHandler logging handler on Windows

[Vinay Sajip]

Vinay Sajip  added the comment:

ConcurrentLogHandler is for multiple *processes* writing to the same
file, not multiple threads in a single process. Python logging does not
support multiple processes writing to the same file because there is no
portable IPC locking across all platforms supported by Python.
ConcurrentLogHandler uses portalocker to achieve interprocess
synchronization, and there is no equivalent mechanism which is part of
the Python stdlib. AFAIK portalocker works on Windows and Linux - I'm
not sure about other platforms.

Python logging *does* support multiple threads in a single process
writing to the same file, which is why I asked Robert if it was
definitely a single-process environment he was working in.

[issue6228] round() error

[steve21]

New submission from steve21 :

I wish to round the float 697.04157958254996 to 10 decimal digits after
the decimal point.

$ python3.0
Python 3.0.1 (r301:69556, Jun  7 2009, 14:51:41)
[GCC 4.3.2 20081105 (Red Hat 4.3.2-7)] on linux2

>>> 697.04157958254996
697.04157958254996  # python float can represent this number exactly

>>> 697.0415795825  # this is the expected result
697.04157958250005  # this is the closest python float representation

round() gives a result that is closer to
697.0415795826
than the expected result of
697.0415795825
- it has not rounded to the closest 10th decimal digit after the decimal
point.
