It’s really only practical if your program is largely I/O bound. If your program is processor bound, then pre-emptive scheduled threads are probably what you really need. Network servers are rarely processor bound, however.</p> <p>If your operating system supports the <tt class="xref c c-func docutils literal"><span class="pre">select()</span></tt> 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 <a class="reference internal" href="#module-asyncore" title="asyncore: A base class for developing asynchronous socket handling services."><tt class="xref py py-mod docutils literal"><span class="pre">asyncore</span></tt></a> module solves many of the difficult problems for you, making the task of building sophisticated high-performance network servers and clients a snap.

To make it more useful, it has a few methods for event-handling which are called from the asynchronous loop. Otherwise, it can be treated as a normal non-blocking socket object.</p> <p>The firing of low-level events at certain times or in certain connection states tells the asynchronous loop that certain higher-level events have taken place. For example, if we have asked for a socket to connect to another host, we know that the connection has been made when the socket becomes writable for the first time (at this point you know that you may write to it with the expectation of success). The implied higher-level events are:</p> <table border="1" class="docutils"> <colgroup> <col width="35%" /> <col width="65%" /> </colgroup> <thead valign="bottom"> <tr class="row-odd"><th class="head">Event</th> <th class="head">Description</th> </tr> </thead> <tbody valign="top"> <tr class="row-even"><td><tt class="docutils literal"><span class="pre">handle_connect()</span></tt></td> <td>Implied by the first read or write event</td> </tr> <tr class="row-odd"><td><tt class="docutils literal"><span class="pre">handle_close()</span></tt></td> <td>Implied by a read event with no data available</td> </tr> <tr class="row-even"><td><tt class="docutils literal"><span class="pre">handle_accept()</span></tt></td> <td>Implied by a read event on a listening socket</td> </tr> </tbody> </table> <p>During asynchronous processing, each mapped channel’s <a class="reference internal" href="#asyncore.dispatcher.readable" title="asyncore.dispatcher.readable"><tt class="xref py py-meth docutils literal"><span class="pre">readable()</span></tt></a> and <a class="reference internal" href="#asyncore.dispatcher.writable" title="asyncore.dispatcher.writable"><tt class="xref py py-meth docutils literal"><span class="pre">writable()</span></tt></a> methods are used to determine whether the channel’s socket should be added to the list of channels <tt class="xref c c-func docutils literal"><span class="pre">select()</span></tt>ed or <tt class="xref c c-func docutils literal"><span class="pre">poll()</span></tt>ed for read and write events.</p> <p>Thus, the set of channel events is larger than the basic socket events.
