Hi all
I'm a little confused about the corner cases of Condition.wait() with a timeout
parameter in the threading module.
When looking at the code the first thing that I don't quite get is that the
timeout should never work as far as I understand it. .wait() always needs to

As part of my Google Summer of Code project I have developed a hstats
module. It reads a file with profile data saved by hotshot and displays
statistics of it after sorting it. The current interface is very basic in
the philosophy of You Arent Gonna Need It[1]. So my question here is:

I'm surprised no one has mentioned zeromq as transport yet. It provides
scaling from in proc (between threads) to inter-process and remote machines in
a fairly transparent way. It's obviously not the python stdlib and as any
system there are downsides too.

Hi
When in a new-style class you can easily transform attributes into
descriptors using the property() builtin. However there seems to be
no way to achieve something similar on the module level, i.e. if
there's a "version" attribute on the module, the only way to change
that to some computation l

Hi
The introduction from the msilib documentation in python 2.5 claims it
supports reading an msi. However on the Record class there is only a
GetFieldCount() method and some Set*() methods. I was expecting to
see GetString() and GetInteger() methods to be able to read the

Hello
I've been trying to figure out how to override methods of a class in
the C API. For Python code you can just redefine the method in your
subclass, but setting tp_methods on the type object does not seem to
have any influcence. Anyone know of a trick I am missing?
