Re: [spice-gtk [rfc] 0/2] Clipboard managers and Spice

Hi,

not a full review, but this is my main concern with this series:

If you enable the new --allow-clipboard-managers property, the
behaviour stays the same as it is at the moment, so you're basically
enabling a bug in the code and it's being advertised as a feature.
This seems just wrong to me.

Given that this use-case seems rather rare and that a fix of the race
(most likely) requires a change of the protocol, I'm still in favour
of accepting a patch like [0] that you sent earlier:

Cheers,
Jakub
