问题描述
我有一个使用POE :: Component :: IRC的简单IRC机器人.只是当我试图通过退出一条有用的消息使它优雅地处理SIGINT时，我发现无论是作为信号处理程序的一部分还是作为常规调用，我都无法使它完全退出任何消息.退出.
I have a simple IRC bot using POE::Component::IRC. It was only when I was attempting to make it gracefully handle SIGINT by quitting with a useful message that I found that I can't make it quit with any message at all, ever whether as part of a signal handler or just a normal call to quit.
比方说，我已经在会话中创建了以下内容:
Let's say I've got the session created something like this:
POE::Session->create(
inline_states => {
irc_disconnected => \&bot_reconnect,
irc_error => \&bot_reconnect,
irc_socketerr => \&bot_reconnect,
connect => \&bot_reconnect,
.
.
.
},
);
bot_reconnect只是要连接回IRC出问题了:
And bot_reconnect is just going to connect back to IRC shouldanything go wrong:
sub bot_reconnect
{
my ($kernel, $heap) = @_[KERNEL, HEAP];
if (1 == $heap->{shutting_down}) {
$heap->{irc}->yield(shutdown => 'blah');
} else {
some_log_func("Reconnecting in 60 secs");
$kernel-delay(connect => 60);
}
}
如果在代码中的其他任何地方，我都将shutting_down设置为1并告诉它要退出(例如$irc->yield(quit => "bye!"))，则立即退出没有退出消息的IRC("Client Quit"(客户端退出)，显示ircd)否则显示远程主机已关闭连接".
If, anywhere else in the code I set shutting_down to 1 and tell itto quit (e.g. $irc->yield(quit => "bye!")) it immediately quitsIRC with either no quit message ("Client Quit", the ircd displays)or else with "Remote host closed the connection".
然后接收到irc_disconnected事件，该事件将其发送到上面的bot_reconnect，其中shutdown似乎不起作用全部.实际上，如果在shutdown之后我没有明确地exit 0然后该过程只是处于混乱状态而没有与IRC的任何连接更多.
It then receives the irc_disconnected event which takes it tobot_reconnect above, where shutdown appears to do nothing atall. In fact if I don't explicitly exit 0 after that shutdownthen the process just stays in limbo with no connect to IRC anymore.
那应该发生什么吗?
我发现:
表示使用shutdown.如您所见，我尝试了似乎不起作用.
which says to use shutdown. As you can see, I tried that, and itdoesn't seem to work.
在另一个问题中，我还找到了一些示例代码:
I also found some sample code for this in another question:
如何正确关闭Bot :: BasicBot机器人(基于POE :: Component :: IRC)?
但是，这与我现在所拥有的非常相似，而且也没有似乎表现出任何不同.
However that is very similar to what I have now, and it also doesn'tseem to behave any differently.
libpoe-component-irc-perl的软件包版本为6.78 + dfsg-1，因此如上面的URL所示，该值应大于6.50.
The package version of libpoe-component-irc-perl is 6.78+dfsg-1 sothat should be greater than 6.50 as the above URL says.
有什么想法吗?
推荐答案
事实证明，这是ircd的故障".
It turns out that this is the "fault" of the ircd.
我也将其报告为POE :: Component :: IRC的请求跟踪程序的错误，Hinrik做出了回应，问我是否要在Freenode上执行此操作. Freenode的ircd具有一项功能，如果您未连接很长时间，它将忽略您的退出消息.
I also reported this as a bug to POE::Component::IRC's request tracker, and Hinrik responded, asking me if I was trying to do this on Freenode. Freenode's ircd has a feature where it ignores your quit message if you haven't been connected for very long.
我没有尝试在Freenode上执行此操作，但事实证明，我在上执行此操作的网络是.他们正在使用Charybdis:
I wasn't trying to do it on Freenode, but it turns out that the network I was doing it on does do this. They're using Charybdis:
