* Test with absurd timeout
* Removed debug timeout
* Better logging and error reporting.
* Preconditions for FollowerInfo.
* Preconditions when updating Current as leader.
* Change a log level.
* Fix unit tests.
* CHANGELOG.
* LOG_TOPIC ids.
* Fix a log id.
* Fix Windows compilation.
* added missing return statements
* only spend up to 10 seconds for initially fetching the list of collections in arangosh
fetching the list of collections is a blocking operation, and the default timeout for this is very high.
If the server is blocked by whatever reason, then the shell is unusable until the collections list request returns.
To avoid this, the initial request is limited to 10 seconds, so the shell can be used afterwards.
* if an index cannot be used for sorting, its sort
cost was previously returned as 0. this will in fact favor
indexes that can be used for filtering but not for sorting
over indexes that can be used for both.
this change is to report the sort cost for indexes that
cannot be used for sorting to n * log(n), where n is the
number of documents that optimizer expects to come out of the
index after filtering
* issue 511.9.1: track DataSource instance instead of only its name in QueryCache
* address use of invalid function
* fix expected test result
* address merge issue
* Bug fix 3.4/bad leader report current (#7574)
* Initialize theLeader non-empty, thus not assuming leadership.
* Correct ClusterInfo to look into Target/CleanedServers.
* Prevent usage of to be cleaned out servers in new collections.
* After a restart, do not assume to be leader for a shard.
* Do nothing in phaseTwo if leader has not been touched. (#7579)
* Drop follower if it refuses to cooperate.
This is important since a dbserver that is follower for a shard will
after a reboot think that it is a leader, at least for a short amount
of time. If it came back quickly enough, the leader might not have
noticed that it was away.
* Forward-port of bug-fix-3.4/mmfiles-replication-get-followers-under-lock
