Line 231 is the @socket.close line. Nothing gets done to the socket
after this, or if it is, it's not getting to it because it crashes on
@socket.close. Nothing should even be touching the entire object after
this, because it sets a flag saying "I'm dead, please GC me."
It's a large program, and the code is available at
http://synapse.malkier.net/browser. The socket closing is in
lib/xmppd/xmpp/stream.rb. The code right there doesn't have the
exception catching written in, because I removed the thing that causes
this to happen, which is this:
# Check for connection timeouts.
#Timer::Timer.new('check connection timeouts', 60, true) do
# $connections.each do |c|
# c.error('connection-timeout') if ($time - c.rtime) >= 30
# end
I'll try putting the exception around this. One second.
No, that doesn't work. Nor does this:
# Check for connection timeouts.
Timer::Timer.new('check connection timeouts', 60, true) do
$connections.each do |c|
next if c.dead? or c.socket.closed?
c.error('connection-timeout') if ($time - c.rtime) >= 30
end
The socket.closed? returns false, then ONE LINE LATER when I call
socket.close, the IOError is raised and cannot seem to be rescued.
Ok, I've updated the code in svn. Relevant files are
http://synapse.malkier.net/browser/trunk/lib/xmppd.rb (which is where
the Timer is started),
http://synapse.malkier.net/browser/trunk/lib/xmppd/timer.rb (which is
the Timers themselves), and
http://synapse.malkier.net/browser/trunk/lib/xmppd/xmpp/stream.rb
(which is where the socket is closing.
This code outputs this:
/Users/rakaur/Sources/wc/ruby/synapse/trunk/lib/xmppd/xmpp/stream.rb:230:in
`ioloop': stream closed (IOError)
from /Users/rakaur/Sources/wc/ruby/synapse/trunk/lib/xmppd.rb:197:in `loop'
from /Users/rakaur/Sources/wc/ruby/synapse/trunk/lib/xmppd.rb:197:in `ioloop'
from ./bin/xmppd:20
Perhaps it has to do with the timers running in a separate thread?
Putting begin/rescue in the tread doesn't catch it, either.
Thanks.
