Re: profiling differences using an extra function call

2009-11-24T02:08:24Z

That's because there is a function call overhead.
A very simple function body will (in terms of percentage) have larger
function overhead. With a slightly more complex function body, the body
will takes much more time than the function call overhead.
Look in the absolute numbers: 0.666 CPU seconds vs. 0.248 CPU seconds

Typo, edited for clarity:
That is: "..the thread can go *away* by itself after the default timeout
expires." You don't need to explicitly kill it.

Graphine does this with the following:
from base import Graph
def K(n):
"""Generates a completely connected undirected graph of size n.
The verticies are numbered [0, n).
The edges are named after the verticies they connect such that
an edge connected verticies 1 and 2 is named (1,2).

Also, if you are using multiple threads to retrieve the xml source(s)
and any thread blocks due to network problems, the thread can go way by
itself after the default timeout expires.

Just file a bug report listing what part you find unclear and what you
suggest they put to clarify it.

Re: Relative versus absolute paths on Windows

Given that it's documented to work that way, I'll agree that this is not
a bug -- however, that doesn't mean it's /right/.
From the documentation:
Join one or more path components *intelligently*.
To me, that means taking into account the bizarre in the MS world of
multiple roots on a system... I know I have looked at os.path.join a

Re: UnicodeDecodeError? Argh! Nothing works! I'm tired and hurting and...

I believe this is the same as
write = sys.stdout.write
though you never use it that I see.
I presume you are expecting the line to be undecoded bytes, as with
open(f,'rb'). To be sure, add write(type(line)).
I do not understand why you are writing since you just wanted to look.
In any case, you open in text mode.

Re: Capturing output of os.system to a string

You can't with os.system; use subprocess module instead.

Capturing output of os.system to a string

2009-11-24T01:27:50Z

How do I capture output to a string? For example, the output of
os.system('whoami').
I guess I need to redirect stdout, but I'm a total beginner, and I
haven't been able to find out from the tutorials how to do this.

Re: Relative versus absolute paths on Windows

2009-11-24T01:23:19Z

No, it's not a bug. Since \bar is an absolute path, all path segments
before the absolute path are ignored. This is documented at
[link]
True
'\\bar'
Posixpath follows the same rules, too.

Hmmm, as I understood the code, either that should be ... 'last': {} ...

{'middle': {'Larry': ['John Larry Smith'],

I find the syntax far to complicated than it should be. Here is an
example just to insert some text..

1. Get the uno component context from the PyUNO runtime
2. Create the UnoUrlResolver
3. Get the central desktop object
