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( u EALREADYu EINPROGRESSu EWOULDBLOCKu ECONNRESETu EINVALu ENOTCONNu ESHUTDOWNu EISCONNu EBADFu ECONNABORTEDu EPIPEu EAGAINu errorcodec C sO y t j | � SWn7 t t t f k rJ | t k r> t | Sd | SYn Xd S( Nu Unknown error %s( u osu strerroru ValueErroru OverflowErroru NameErroru errorcode( u err( ( u- /opt/alt/python33/lib64/python3.3/asyncore.pyu _strerrorD s u _strerrorc B s | Ee Z d Z d S( u ExitNowN( u __name__u __module__u __qualname__( u __locals__( ( u- /opt/alt/python33/lib64/python3.3/asyncore.pyu ExitNowL s u ExitNowc C s; y | j � Wn& t k r% � Yn | j � Yn Xd S( N( u handle_read_eventu _reraised_exceptionsu handle_error( u obj( ( u- /opt/alt/python33/lib64/python3.3/asyncore.pyu readQ s u readc C s; y | j � Wn& t k r% � Yn | j � Yn Xd S( N( u handle_write_eventu _reraised_exceptionsu handle_error( u obj( ( u- /opt/alt/python33/lib64/python3.3/asyncore.pyu writeY s u writec C s; y | j � Wn& t k r% � Yn | j � Yn Xd S( N( u handle_expt_eventu _reraised_exceptionsu handle_error( u obj( ( u- /opt/alt/python33/lib64/python3.3/asyncore.pyu _exceptiona s u _exceptionc 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 Wnw t j k r� } z/ | j d t k r� | j � n | j � WYd d } ~ Xn& t k r� � Yn | j � Yn Xd S( Ni ( u selectu POLLINu handle_read_eventu POLLOUTu handle_write_eventu POLLPRIu handle_expt_eventu POLLHUPu POLLERRu POLLNVALu handle_closeu socketu erroru argsu _DISCONNECTEDu handle_erroru _reraised_exceptions( u obju flagsu e( ( u- /opt/alt/python33/lib64/python3.3/asyncore.pyu readwritei s" u readwriteg c C s� | d k r t } n | r�g } g } g } x� t | j � � D]v \ } } | j � } | j � } | rz | 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 | | | | � \ } } } Wn t k r/d SYn Xx9 | D]1 } | j | � } | d k r^q7n t | � q7Wx9 | D]1 } | j | � } | d k r�qsn t | � qsWx< | D]1 } | j | � } | d k r�q�n t | � q�Wn d S( N( u Noneu socket_mapu listu itemsu readableu writableu appendu acceptingu timeu sleepu selectu InterruptedErroru getu readu writeu _exception( u timeoutu mapu ru wu eu fdu obju is_ru is_w( ( u- /opt/alt/python33/lib64/python3.3/asyncore.pyu poll} sJ ' % u pollc C sK | d k r t } n | d k r4 t | d � } n t j � } | rGx� t | j � � D]t \ } } d } | j � r� | t j t j BO} n | j � r� | j r� | t j O} n | rY | j | | � qY qY Wy | j | � } Wn t k r� g } Yn XxE | D]: \ } } | j | � } | d k r3qn t | | � qWn d S( Ni� i ( u Noneu socket_mapu intu selectu pollu listu itemsu readableu POLLINu POLLPRIu writableu acceptingu POLLOUTu registeru InterruptedErroru getu readwrite( u timeoutu mapu pollsteru fdu obju flagsu r( ( u- /opt/alt/python33/lib64/python3.3/asyncore.pyu poll2� s. u poll2g >@c C s� | d k r t } n | r3 t t d � r3 t } n t } | d k rb xJ | r^ | | | � qH Wn0 x- | r� | d k r� | | | � | d } qe Wd S( Nu polli i ( u Noneu socket_mapu hasattru selectu poll2u poll( u timeoutu use_pollu mapu countu poll_fun( ( u- /opt/alt/python33/lib64/python3.3/asyncore.pyu loop� s u loopc B s� | Ee Z d Z dB Z dB Z dB Z dB Z dB Z dA Z e d g � Z dA dA d d � Z d d � Z e Z dA d d � Z dA d d � Z e j e j d d � Z dA d d � Z d d � Z d d � Z d d � Z d d � Z d d � Z d d � Z d d � Z d d � Z d d � Z d d!
