Susan Hinrichs updated TS-3272:
-------------------------------
    Attachment: ts-3272-4.diff
                ts-3272-master.diff

Lev noticed, that the PreAccept callback no longer works with the 
ts-3272-3.diff patch (which has been commited to master).

Tracing through, we have a HandShake buffer in this case, but it is empty.  The 
code copies over the data in the buffer (count 0) and issues a READ_COMPLETE, 
but the underlying handler does a close on the vc if it gets a READ_COMPLETE 
and the read count is less than 1.

So added logic to only issue the second READ_COMPLETE if in fact there is data 
in the HandShake buffer.

I'm attaching this as two patches.  ts-3272-4.diff should include all the 
changes for this bug (including those already committed to master).  
ts-3272-master, only contains this latest fix and not the changes already 
committed to master.

> I have created a simple plugin with TS_SSL_SNI_HOOK handler. Handler starts 
> thread. Thread function has small sleep and after that calls TSVConnTunnel.
> The problem is that during sleep duration TS_SSL_SNI_HOOK handler gets 
> continuously called.
> I would expect that TS_SSL_SNI_HOOK handler should be called just once.
> See plugin code in attach.
