Subject: [PATCH 1/2] Defer sending a KeyUpdate until after pending writes are
|
|
complete
|
|
|
|
If we receive a KeyUpdate message (update requested) from the peer while
|
|
we are in the middle of a write, we should defer sending the responding
|
|
KeyUpdate message until after the current write is complete. We do this
|
|
by waiting to send the KeyUpdate until the next time we write and there is
|
|
no pending write data.
|
|
|
|
This does imply a subtle change in behaviour. Firstly the responding
|
|
KeyUpdate message won't be sent straight away as it is now. Secondly if
|
|
the peer sends multiple KeyUpdates without us doing any writing then we
|
|
will only send one response, as opposed to previously where we sent a
|
|
response for each KeyUpdate received.
|
|
|
|
Fixes #8677
