[kgb-maintainers] kgb-bot.deb and dropping RateLimit

[Damyan Ivanov]

Hi there,

With the kind help of Tincho, the "shadow" notifications problem shall 
be fixed in trunk. In the process, I have acquired some POE-foo, which 
may result in more drastic changes in the KGB bot in the future :))

Here's my next idea that needs some support.

Next thing I am targetting is putting the thing in Debian. We shall 
not hide it any more. The only serios obstacle for archive inclusion 
is the inclusion of Schedule::RateLimiter code into kgb-bot source.

The module is rather small, last release in 2003, so not very 
appealing for archive upload. There is an alternative, 
Algorithm::TokenBucket, from February 2008, which is also just 
a couple of tens of lines of code.

OTOH, RateLimiter docs mention that POE has a more heavy-weight 
solution to the rate limitting problem, so I took a look. It seems 
PoCo::IRC has a throttling mechanism that doesn't allow it to flood 
IRC networks. It is enabled by default and not configurable. It is in 
the sl_delayed sub and sets a limit of about 120 chars/second minus 
2 seconds per message.

So I was wondering if we shall drop RateLimiter usage and return "I'm 
overloaded" SOAP error if the sending queue of the PoCo::IRC, whose 
size is available in the send_queue method, grows beyound (say) 15 
messages. Does this seem right to you?
