Sudheer Vinukonda commented on TS-2983:
---------------------------------------
Thanks, [~zwoop]..If everyone agrees to not probe the SSL connection, I would
not mind that very much :=)
[[email protected]] - Just to understand the mystery, I was looking at the
changes in TS-2751 and was wondering if the newly added ProtocolProbeTrampoline
does "everything", that the SSLNextProtocolTrampoline did for SSL connection
prior to TS-2751. In particular, I was curious about the below comments in
SSLNextProtocolAccept.cc indicating that the continuation that's handling the
read event must have a mutex etc. Perhaps, I am missing something, but, it
seemed to me that the new ProtocolProbeTrampoline did not seem to have such a
mechanism?
{code}
"// SSLNextProtocolTrampoline is the receiver of the I/O event generated when
we perform a 0-length read on the new SSL
// connection. The 0-length read forces the SSL handshake, which allows us to
bind an endpoint that is selected by the
// NPN extension. The Continuation that receives the read event *must* have a
mutex, but we don't want to take a global
// lock across the handshake, so we make a trampoline to bounce the event from
the SSL acceptor to the ultimate session
// acceptor.

> After a lot of debugging, figured that the request was getting corrupted even

> 30fcc2b2e698831d1a9e4db1474d8cfc202818a3 in Oct'13), which has altered the
