Re: [jetty-users] Dependency tree built

[Muhui Jiang <jiangmuhui@xxxxxxxxx>]

BTW: Something wanna make sure with you Simone.

I saw you just create another construct method for HeadersFrame with the default streamid 0;

But here I am not so clear what do you mean

>We were sending the streamId as the parentStreamId
>and viceversa.

If you are available, could you please give me a short example. For example, I have  requests A ,B & C. I hope the dependency tree can be this:

       A

     /     \

   B      C 

And then their HeadersFrame is

HeadersFrame A = new HeadersFrame(?,?,new PriorityFrame(?,?,?,?),?)

HeadersFrame B = new HeadersFrame(?,?,new PriorityFrame(?,?,?,?),?)

HeadersFrame C = new HeadersFrame(?,?,new PriorityFrame(?,?,?,?),?)

Thank you very much.

Best Regards

Thanks Simone.

I am going to have a try on it. I will tell you the result later.

Okay, my mistake. We were sending the streamId as the parentStreamId
and viceversa.
That was probably the reason H2O did not apply any priority logic,
since the stream ids were sent wrong.

This is also fixed.

Can you please try and build the "master" branch, and try again to see
if H2O now applies the priority logic ?

Thanks !
