Max Neunhöffer f3acea797b Feature/cluster inventory version (#3152) 
* Get rid of a compiler warning in community edition.

* Teach /_api/replication/clusterInventory to report Plan/Version and readiness.

This is first implemented in the ClusterInfo library.
Then the clusterInventory code uses it and checks readiness.
Readiness of a collection means that it is created and all shards
and all replications have been created and are in sync.

Jan 8e65fbb539 Bug fix/issues 1708 (#3060) 
* we must now ignore that datafiles are not sealed

this is because an unsealed datafile may have been produced by
renaming multiple journals to datafiles at server start

* acquire collection count after we have acquired the lock

* count the null byte as well

* fix count value acquisition

* send query fragments to the correct servers, even after failover or when a follower drops

the problem with using the previous shard-based approach is that responsibilities for shards may change at runtime
however, an AQL query must send all requests for the query to the initially used servers.
if there is a failover while the query is executing, we must still send all following requests to the same servers, and not the newly responsible servers
otherwise we potentially would try to get data from a query from server B while the query was only
instanciated on server A.

Michael Hackstein 4f899bfd2c Integreated a ShortestPathEngine on DBServers and wired it up with ShortestPathNode and Options. The path seems to be computed correctly in clsuter now, but the vertices are not yet retrieved. 2017-04-20 13:57:14 +02:00
