[Bug 1828608] Re: Chardev websocket might not support pasting more than a few chars

[Thomas Huth]

The QEMU project is currently considering to move its bug tracking to
another system. For this we need to know which bugs are still valid
and which could be closed already. Thus we are setting older bugs to
"Incomplete" now.

If you still think this bug report here is valid, then please switch
the state back to "New" within the next 60 days, otherwise this report
will be marked as "Expired". Or please mark it as "Fix Released" if
the problem has been solved with a newer version of QEMU already.

Thank you and sorry for the inconvenience.

Title:
  Chardev websocket might not support pasting more than a few chars

Status in QEMU:
  Incomplete

Bug description:
  When sending more than 4-5 characters on the websocket serial console
  (with pasting for example), the guest might not receive all of them,
  or worse interpret the input as Magic SysRq keys.

  This might be due to the io loop not checking the backend readiness
  before calling the read function.

  Attached patched fixes the problem on my system. I'm not sure it's the
  proper approach, this is just to start discussion.
