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. i����N( t EALREADYt EINPROGRESSt EWOULDBLOCKt ECONNRESETt EINVALt ENOTCONNt ESHUTDOWNt EINTRt EISCONNt EBADFt ECONNABORTEDt EPIPEt EAGAINt errorcodec C sK y t j | � SWn3 t t t f k rF | t k r> t | Sd | SXd S( Ns Unknown error %s( t ost strerrort ValueErrort OverflowErrort NameErrorR ( t err( ( s /usr/lib64/python2.7/asyncore.pyt _strerrorD s t ExitNowc B s e Z RS( ( t __name__t __module__( ( ( s /usr/lib64/python2.7/asyncore.pyR L s c C s9 y | j � Wn$ t k r$ � n | j � n Xd S( N( t handle_read_eventt _reraised_exceptionst handle_error( t obj( ( s /usr/lib64/python2.7/asyncore.pyt readQ s c C s9 y | j � Wn$ t k r$ � n | j � n Xd S( N( t handle_write_eventR R ( R ( ( s /usr/lib64/python2.7/asyncore.pyt writeY s c C s9 y | j � Wn$ t k r$ � n | j � n Xd S( N( t handle_expt_eventR R ( R ( ( s /usr/lib64/python2.7/asyncore.pyt _exceptiona s c C s� yz | t j @r | j � n | t j @r7 | j � n | t j @rQ | j � n | t j t j Bt j B@ry | j � n Wnc t j k r� } | j d t k r� | j � q� | j � n$ t k r� � n | j � n Xd S( Ni ( t selectt POLLINR t POLLOUTR t POLLPRIR t POLLHUPt POLLERRt POLLNVALt handle_closet sockett errort argst _DISCONNECTEDR R ( R t flagst e( ( s /usr/lib64/python2.7/asyncore.pyt readwritei s" g c C s | d k r t } n | r�g } g } g } x� | j � D]v \ } } | j � } | j � } | rt | j | � n | r� | j r� | j | � n | s� | r: | j | � q: q: Wg | k o� | k o� | k n r� t j | � d Sy% t j | | | | � \ } } } Wn3 t j k rF} | j d t k r?� qGd Sn Xx9 | D]1 } | j | � } | d k ruqNn t | � qNWx9 | D]1 } | j | � } | d k r�q�n t | � q�Wx< | D]1 } | j | � } | d k r�q�n t | � q�Wn d S( Ni ( t Nonet socket_mapt itemst readablet writablet appendt acceptingt timet sleepR!
