broadcast LCC+delay issue #13035

Open ornicar opened 1 year ago

ornicar commented 1 year ago

as seen in the broadcast channel:


There is something wrong with LiveChessCloud + lila delay combination specifically https://lichess.org/broadcast/delay-check-2/fzfsmjkw

Chapter 1: LiveChessCloud + lila delay Chapter 2: LiveChessCloud -> mule + lila delay Chapter 3: LiveChessCloud (no delay)

Chapters 2 and 3 are working fine, they are receiving new moves (2 new moves 15 Jun, 13:57:08 ...)

Chapter 1 is stuck in an old state

I was testing the delay in another test broadcast. It loaded the moves, but never updated. That's the same "old state" that Chapter 1 is stuck with

As a temporary fix, we can replace LCC with mule in the delayed broadcasts (that use LCC)

Currently it's just US National Open 2023 and US Women's National Open 2023, right? Las Vegas Walter Browne Memorial Blitz in 2 days.

Looks like it, other broadcasts are either not delayed or don’t use an LCC

:ok: I'll set mule reminders for both National Opens and change the sources

Running one more test with the Turkish tournament starting in 13 minutes https://lichess.org/broadcast/delay-check-2/event-2-lcc--120s/5nMhOBru

Yup, the same thing is happening

I think if we reset chapter 4 (LCC + delay), it will load the moves once, but won't update after that. Let's save that for the devs to see, though.

We are experiencing delay problems other than the LCC At French Youth Championships 2024 is with Lila delay And since there is a private version that has no delay The one without delay works perfectly With delay: mode takes several minutes to start (until disconnections occur) or halfway through the event the delay stops and does not update the movements, which in turn can also cause disconnections

It is not the first time that there has been suspicion about the last one but it has become clear now
