Hello
recently, I met a problem with one python application running with
python2.5 | debian/lenny adm64 system: it crashed occasionally in our
production environment. The problem started to happen just after we
upgraded the python application from python2.4 | debian/etch amd64.

A simple thread pool example. My question is, since *MyThread.run*
will loop endless, how does the thread know the time to quit? how does
the *queue* notify the thread? is there any shared variables, like a

When I set daemon false, it stays in the loop, not quit any more.

Hello.
I read a string from an utf-8 file:
fichierLaTeX = codecs.open(sys.argv[1], "r", "utf-8")
s = fichierLaTeX.read()
fichierLaTeX.close()
I can then print the string without error with 'print s'.
Next I parse this string:
def parser(s):
i = 0
while i < len(s):
if s[i:i+1] == '\\':

But you should be aware of the effeciency implications of doing

Yup:

For instance, this seems to be correct :
>>> z=[45,12,96,33,66,'c',20,99]
>>> del z[2], z[6],z[0]
>>> z
[12, 33, 66, 'c', 20]

However, the following doesn't work :

Hi everyone,
I have a production server running a Windows Service written in Python, which
uses python 2.5.4 (yes I know it is old, but I am somewhat stuck with this for
now) and pywin32 214.
Given a set of manipulations, I get a stack overflow in the service, and a bad
crash. The same opera
I'm looking for a Python-based, small, self-contained package to
hand out API keys, in the same spirit as Google API keys.
The basic specs are simple: 1) enforce the "one key per customer"
rule; 2) be robot-proof; 3) be reasonably difficult to circumvent
even for humans.
(This is for a web se
I have a function exposed through ctypes that returns a c_char_p.
Since I need to deallocate that c_char_p, it's inconvenient that
ctypes copies the c_char_p into a string instead of giving me the raw
pointer. I believe this will cause a memory leak, unless ctypes is
smart enough to free the string

Your withhacks module looks very interesting.

What are your specific concerns about its use? Are there portability
concerns?

It is guaranteed that objects with a reference count of zero will be
disposed. In my experiments, this happens immediately.
