Hi,
We're in a discussion on the APR dev mailing list regarding a problem
with tcnative on XP. On XP the poller implemented in APR with select()
is being used. According to Jeff Trawick of APR, select can never give
an APR_POLLHUP return event (see
http://mail-archives.apache.org/mod_mbox/apr-dev/201105.mbox/browser).
I followed the discussion and the ideal solution would be to make sure
that the correct flags are returned.
In the case where we encounter 100% cpu usage when the client connection
has gone, processSocket() returns true (as almost always). Is this
intended or wopuld this be a place where a fix could be introduced
following the line of Jeff Trwick's message mentioned above?
I suppose the problem is that inside Tomcat we don't check the data
processed. Here the solution would be that if the socket comes out
from the Poller with POLLIN and the subsequent read returns 0 we
should close that socket instead putting it back to Poller.
I presume this is what's going on, right?
