Volatile fields in the decoders

[Frederic Bregier]

Hi Trustin,

For me; I agree that most of the time, Codec are before ExecutionHandler.
In fact, I have no real idea of other cases, except, if I search the extreme case, when one wants to "pipeline" two kinds of channels, for instance:
"network-channel -> one codec -> execution handler -> business handler which writes on local-channel -> another codec -> another execution handler -> another business handler"

I do this to pipeline several "business" stream into one network-channel.
My guess is that probably there the codec for the local channel (the one in the middle named another codec) must be ok for multiple thread suport.
Perhaps not all codec are necessary for that.
Also I'm not completely sure that my example is a good one.. Just a guess more than an example...
WDYT ?

Frederic

  Hi folks, 

  Currently, all decoders distributed with Netty define their state 
  fields as volatile, because I assumed that the decoders might be 
  placed after ExecutionHandler.  However, nobody seem to place them 
  after ExecutionHandler because decoding is a CPU bound task. 
  Therefore, I'd like to remove the volatile modifier if I did not miss 
  anything.  Please feel free to post your idea - it will be very 
  helpful regardless whether it's agreement or disagreement. 

  Thanks
