#7166: erratic disconnects  from yahoo messenger

 For the past couple days, Yahoo messenger's server will kicked me out it
 in random. I am on pidgin 2.5.1 using windows xp prof.

 I spoke to Y's customer service, and I was told that pidgin is sending too
 many pings to their servers, so they treated pidgin clients as spammers,
 as a result, connections are dropped.

 While observing both Yahoo messenger (8.x and 9.x) and pidgin on ethereal,
 I see that pidgin is sending ping every 30 secs. Y's messenger clients are
 sending one ping per ~1hr.

 On even closer inspection, it looks like during the initial connect to Y's
 server, YAHOO_SERVICE_PING includes 143 and 144. 60 is assigned to 143,
 and 1 is assigned to 144. If my guess is right, 143 is the ping timeout in
 min, so 60min is 1hour.

 I skimmed through libpurple code a little, and I only see send_keepalive
 function (which sends a keepalive every 30 (sec which is my guess)), but
 no send_ping function. And I think libpurple is using this for both ping
 and keepalive.

 Can someone that's familiar with the libpurple confirm what I found is
 correct? And of course, a solution will be greatly appreciated too.

 Thanks a lot!
