* Removed unused active(...) method in Agent
* Inception's restart from persistence allows peer with empty active RAFT list to join
* Agency's UUID is persisted outside of the database comparable to coordinator and db server action.
* Publicized Methods to UUID stuff in ServerState
* Inception method documentation
* added --agency.disaster-recovery-id to allow for specification of known former agency id. this is a very dangerous option potentially.
* Delete a unused methods.
* separate _id and _recoveryId
* populating active list with entire pool
* Improve logging.
* reject gossip from unknown agent, if pool is complete
* Send out empty heartbeats regardless of non-empty AppendEntriesRPC.
* Also improve logging:
Note if a log in the empty heartbeat sending takes > 0.01 s.
Clearly mark places where a leader resigns in logging.
Log if no empty heartbeat is sent out.
* Make leader more tolerant w.r.t. incoming AppendEntriesRPC responses.
* Add debug logging for _lastAcked and challengeLeadership.
* Remove some unused code. Do not count ourselves in challengeLeadership.
* Removal of entire activation/deactivation mechanisms in agency
* TRI_microtime up to c++11
* added term to response to sendAppendEntries.
Also improve logging:
Note if a log in the empty heartbeat sending takes > 0.01 s.
Clearly mark places where a leader resigns in logging.
Log if no empty heartbeat is sent out.
* fixed a bug, where when servers failed, when also agency leadership changes
* redid entire design of checkDBServers/checkCoordinators.
* comparison in supervision must be between oldPersisted and newHealth
* UI stuff
* UI stuff
* FailedServer test needed adjustment
* Hopefully final round
* fixed supervision failure detection
* FailedServer tests back to origin devel
* oldNot documented among preconditions in Agency HTTP API docs
* changed only look for status updated
* non action line in api-cluster
* added debugging methods
* try to fix invalid access in case of error
* remove unused members
* bugfixes and comments
* all agency fixes in
* merge bug
* partially unguarded Agent::lead fixed
* all agency fixes in
* added nrBlocked to thread startup eval
* added nrBlocked to thread startup eval
* recombination of cases in State::get
* some maps replaced with unordered_maps
* optimized maps some
* Take out 503 timeouts altogether.
* Overhaul of AgencyComm::sendWithFailover loop.
* Let performRequests optionally ignore 404 coll not found.
* Fix error message "database not found" when AgencyComm failed.
* Add log entries in Agency if locks are acquired too slowly.
* Reexecute the javascript cluster sync stuff even if there was no plan/current change...So failed sync jobs can retry later...
* Cover callbacks in Communicator by lock. This fixes https://github.com/arangodb/planning/issues/370
* Put in delay in waiting for leader in agency test.
* Schmutz logging to heartbeat topic.
* Add more lock time diagnostic in agent.
* Switch on agencycomm tracing in coordinator.
