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. � N) �EALREADY� EINPROGRESS� EWOULDBLOCK� ECONNRESET�EINVAL�ENOTCONN� ESHUTDOWN�EISCONN�EBADF� ECONNABORTED�EPIPE�EAGAIN� errorcodec C sO y t j | � SWn7 t t t f k rJ | t k r> t | Sd | SYn Xd S)NzUnknown error %s)�os�strerror� ValueError� OverflowError� NameErrorr )�err� r �-/opt/alt/python34/lib64/python3.4/asyncore.py� _strerrorD s r c @ s e Z d Z d S)�ExitNowN)�__name__� __module__� __qualname__r r r r r L s r c C s; y | j � Wn& t k r% � Yn | j � Yn Xd S)N)�handle_read_event�_reraised_exceptions� handle_error)�objr r r �readQ s r c C s; y | j � Wn& t k r% � Yn | j � Yn Xd S)N)�handle_write_eventr r )r r r r �writeY s r" c C s; y | j � Wn& t k r% � Yn | j � Yn Xd S)N)�handle_expt_eventr r )r r r r � _exceptiona s r$ 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 Wnt t k r� } z/ | j d t k r� | j � n | j � WYd d } ~ Xn& t k r� � Yn | j � Yn Xd S)Nr )�select�POLLINr �POLLOUTr! �POLLPRIr# ZPOLLHUPZPOLLERRZPOLLNVAL� handle_close�OSError�args� _DISCONNECTEDr r )r �flags�er r r � readwritei s" r/ g 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)� socket_map�list�items�readable�writable�append� accepting�timeZsleepr% �InterruptedError�getr r" r$ ) �timeout�map�r�wr. �fdr Zis_rZis_wr r r �poll} sJ ' % r?
