在libevent 为这些需要忽略的errno定义了宏 EVUTIL_ERR_ACCEPT_RETRIABLE,宏里定义了上面三个需要忽略的信号,在 accept 处理时会判断如果遇到这些信号则进行忽略,下次重试就好。 /* True iff e is an error that means a accept can be retried. */ #defineEVUTIL_ERR_ACCEPT_RETRIABLE(e) \ ((e) == E...

This means that a TCP RST was received and the connection is now closed. This occurs when a packet is sent from your end of the connection but the other end does not recognize the connection; it will send back a packet with the RST bit set in order to forcibly close the connection. ...

Theerrnovariable is set to certain error values by many functions whenever an error has occurred. Theerrnovariable may be implemented as a macro, but you can always examine or set it as if it were a simple integer variable. Each thread in a multi-threaded program has its own error value ...
0 means that the data will be loaded in the main process. (default: 0) num_workers参数允许输入的数据类型是整型,表示加载数据的子进程数。也就是使用多进程来加载数据,这样效率更高一些。如果设置为0表示子进程数是0,也就是只用一个主进程来加载数据。数据量不多的情况下,不需要用多进程,因为进程的...
# Set to yes to apply rules to support IPv6 (no means only IPv6 on loopback # accepted). You will need to 'disable' and then 'enable' the firewall for # the changes to take affect. IPV6=no In my case setting it to IPV6=yes followed by disabling and enabling ufw fixes the ...

This probably means that you are not using fork to start your child processes and you have forgotten to use the proper idiom in the main module: if __name__ == '__main__': freeze_support() ... The "freeze_support()" line can be omitted if the program ...
