New submission from Beda Kosata:
While re.sub normally returns unicode strings when processing unicode,
it returns a normal string when dealing with an empty unicode string.
Example:
print type( re.sub( XX, , u))
type 'str'
print type( re.sub( XX, , uA))
type 'unicode'
This inconsistency
Vinay Sajip added the comment:
I'm not sure I agree with If fileConfig has no delay_fh option,
fileConfig() would create the FileHandlers with delay_fh as False.
fileConfig will create the FileHandlers using the args= section entry to
pass to the constructor. Hence, by specifying True for this

September 11, 2007 I downloaded py 3.k
The good news :
Under Windows, Python 3k properly reads files larger than 4 Go (in
contrast to python 2.5 that skips some lines, see below)
The bad news : py 3k is very slow compared to py 2.5; see the results below

If you would like to help resolving the issue with the missing lines,
please submit a separate report for that. It is very difficult to track
unrelated bugs in a single tracker issue. It would help if you could
determine which lines are missing, e.g. by writing

Hi Martin
I could certainly do that, but how you get my huge files ? 5 Go of data
is quite big...
If you want to compute runtimes, it is better to not convert them to
local time. Instead, use the pattern
start = time.time()
...
print time.time()-start #
Chris Leary added the comment:
Ah, I see what the miscommunication is now.
Yes, implementing the feature as you suggested would give the user the
ability to specify the delayed handle-opening /within/ the configuration
file. What I had intended was a way to load/inspect a file configuration
Martin v. Löwis added the comment:

[not sure what that is] I did not mean to suggest that you attach such
a large file. Instead, just report that as a separate bug report, and be
prepared to answer
Stefan Sonnenberg-Carstens added the comment:
Perhaps this is an issue of line separation ?
Could you provide the output of wc -l on a *NIX box ?
And, could you try with this code:
import sys
print(sys.version_info)
import time
print (time.localtime())

Hi Stefan

Actually, it already implements the best possible rules, *except* for
the special case of an empty 3rd argument. (When there are no
substitutions, it normally returns the input unchanged; but somehow an
empty input is handled with a shortcut even before that

I think the example in Lib/test/test_ssl.py will have to suffice.

Looks like a *documentation* bug to me; at the implementation level,
None just means no empty parts, treat runs of whitespace as separators.

Nir Soffer added the comment:
I did not look into the source, but obviously there is striping of
leading and trailing whitespace.
When you specify a separator you get:
' '.split(' ')
['', '', '']
' a b '.split(' ')
['', 'a', 'b', '']
So one would expect to get this without striping:

As I said, the *implementation* treats runs of whitespace as
