4b5aa5ed72 [#1402] Added a sentence into ARM 
It says that the synchronization is also required when the
delayed-updates-limit is exceeded when the server is in the
communication-recovery state.

5f87bb512f [#1402] Send ha-reset to partner 
The ha-reset command is sent to the partner when communication is
re-established but the lease backlog is overflown or an attempt to send
lease updates failed. This causes the partner to synchronize its lease
database with the server sending ha-reset.

single std::deque, as requested in review comment.

9ab9bc9b90 [#1402] Watch for invalid partner state 
If the local server detects that its partner is in an unexpected state
it will transition to the waiting state. Insufficient checks were indicated
in the review comments.

ccbe6410d5 [#1402] Trivial changes to HAService tests 
For tests which verify the case of communication recovery failure, moved
listeners startup into the test part that checks that communication
can be re-established, per review comments.

723eb8f238 [#1402] LeaseUpdateBacklog is no longer a template 
LeaseUpdateBacklog now holds LeasePtr and is no longer a template class
as suggested in review comments. Classes using this class were simplified.
In particular, the HAService class has now only one backlog queue.

fce77a2dad [#1402] Correct wrong log message 
When the server transitioned to the communication-recovery state it used
to say that lease updates will be sent in that state. In fact, the updates
are not sent (but they are queued). The code was corrected to address this.
 2021-01-13 10:11:31 +01:00

3658bfb585 [#1402] Comm recovery enabled via config 
There is a new parameter, delayed-updates-limit, which can be used to
enable communication-recovery state in the load-balancing mode and control
how many lease updates can be queued while being in this state.

392c2640ad [#1402] Sending lease updates backlog 
A backlog of lease updates is sent to a partner upon resuming communication
between the servers. If any of the lease updates fails, we simply
transition to the waiting state and let them re-synchronize.

2657ddb456 [#1402] Collect unsent lease updates 
In the communication-recovery state, the server collects unsent lease
updates with an intent to send them later when communication with the
partner is back.

4249525828 [#1402] Added lease updates backlog queue
