"""Basic infrastructure for asynchronous socket service clients and servers.
|
||||
|
||||
There are only two ways to have a program on a single processor do "more
|
||||
than one thing at a time". Multi-threaded programming is the simplest and
|
||||
most popular way to do it, but there is another very different technique,
|
||||
that lets you have nearly all the advantages of multi-threading, without
|
||||
actually using multiple threads. it's really only practical if your program
|
||||
is largely I/O bound. If your program is CPU bound, then pre-emptive
|
||||
scheduled threads are probably what you really need. Network servers are
|
||||
rarely CPU-bound, however.
|
||||
|
||||
If your operating system supports the select() system call in its I/O
|
||||
library (and nearly all do), then you can use it to juggle multiple
|
||||
communication channels at once; doing other work while your I/O is taking
|
||||
place in the "background." Although this strategy can seem strange and
|
||||
complex, especially at first, it is in many ways easier to understand and
|
||||
control than multi-threaded programming. The module documented here solves
|
||||
many of the difficult problems for you, making the task of building
|
||||
sophisticated high-performance network servers and clients a snap.
