-

So, this patch throws a VC_EVENT_DO_CLOSE event at a NetVC, but it doesn't 
record that fact that the event is outstanding?   What prevents the NetVC from 
being deallocated before the event is processed?

-

So, this patch throws a VC_EVENT_DO_CLOSE event at a NetVC, but it doesn't 
record that fact that the event is outstanding?   What prevents the NetVC from 
being deallocated before the event is processed?

 ] 

Alan M. Carroll commented on TS-857:


Where would it record the pending event? The presumption is that the only other 
thread that might close it is the one that will process the event.

But the real issue is that sometimes the lock is dropped between the time the 
lock try is done and the event is scheduled, leading to scheduling on the null 
thread. If you look at TS-934 you can see how that issue is handled there, but 
even that's not sufficient because normal VC processing from 
NetHandler::mainNetEvent does not lock the VCs, so there isn't any way do 
anything safely in this case.

 ] 

Alan M. Carroll commented on TS-857:


I have reviewed the patch and it looks basically correct to me. I had a few 
style issues, which I have corrected in my version of the patch.

* I put the new event type in iocore/eventsystem/I_VConnection.h where the 
other VConnection events are.
* Added some comments.
* Fixed a broken comment in I_Event.h which misdirected me about schedule_imm 
in my earlier work. I found the correct comment in a very old copy of the file 
and put it back.

I am currently doing some live testing, but I would like to commit this for 
3.1.1.
