* Remove some changes introduced by the merge
* Fixed compile errors introduced by merge
* Modified header to new initializeCursor API
* Adapted initializeCursor to DONE/WAITING API. Compiles but not tested and no one reacts to WAITING state, it is not returned anywhere yet
* Subqueries now expect a WAITING return from initilize cursor. However they will just return a nullptr and pretend the query is empty, this will be fixed later
* First attempt to simulate thread waiting over information within the query
* Small fix to allow for isDirect handlers to go to sleep.
* Waiting in the necessary places now for the async request to be send.
* Thank you auto-casting compiler, you are totally right i absolutely wanted to use this bool value as an index in may Array. How could i possibly not want to use it here?
* Include cond-var header
* Fixed mutex/cond_var usage
* Added oldAPI wrappers in AQL Blocks for get/skip some variants. This Commit compiles but is NOT tested
* Let getSome now return unique_ptr of AqlItemsBlocks. Also implemented the async variant of getSome in subqueries.

* Fixed endless virtual recursion
* Implemented new getOrSkip API in SortBlock
* Implemented new getOrSkip API in LimitBlock
* Initilaize all variables
* Fixed logic bug in SubqueryBlock
* getBlock in ExecutionBlock now returns a state. All blocks need to handle this properly!
* Createad a wrapper getBlockOld that servers the old sync api and is used now in AQL. To be replaced overtime.

* This commit implements waking up of AQL queries. (#5651)
* Non-compiling intermediate commit for handover.
* Make branch compile again
* Started implementation of continueable rest cursor handler by moving the callbacks to the outer part. This is not yet fully tested!
* Made finalizeExecute noexcept. We cannot react to this errors as the response was potentially written before. Also introduced continueExecution in the RestHandler engine.
* First successful query wakeup.
* The wakeup callback now posts on the scheduler directly. A resthandler only needs to provide a callback that encapsulates the continueExecution call on this handler
* renamed finalizeExecute to shutdownExecute
* Added a differentiation between Handler and Callback in Query continuation. Handler will be posted in IO service. Callback will be executed directly
* fix audit log
* Removed callback from deleteQueryCursor. This cannot be waiting
* use CONDITION_LOCKER
* removed yet another thread-local variable
* Fixed forward declaration
* Made RestAqlHandler repeatable
* Use defer to close the query in RestAqlHandler. Now waiting will close the query as well.
* Added a mutex in the RestHandlers to make sure if the callback over network is too fast that there is only one Thread running in the RestHandler
* Captured the GeneralCommTask if it is posted to a RestHandler. This is necessary in the PAUSED case
* Refactoring of _noLockHeader responsibilities. Now the BaseHandler selects them and resets them after it is done. Only Coordinators are allowed to define them if a query is loaded.
* Removed reaction to existing nolockheaders in Coordinator Query Planning Phase
* Removed incorrect assertion.
* Further refactoring of NoLockHeaders. Now there is a wrapper class around it which allows for debugging and logging. The state now seems to be better. Also all non-rest-handler triggered queries clean up the NoLockHeaders properly.
* Fixed UserManager, now deletes nolock headers properly
* Swing to the Symphony of Destruction
* Forgot about community build...
* Fixed compiling of Catch tests
* Fixed community build
* need thread for size
* Made the restSimpleHndler repeatable

* Reactivated StreamingCursors
* Removed debug output.
* Fixed false query continuation
* Reset thread output to non-debug
* Added missing return statements
* Allow some CollectionMethods to hand-in a context that may contain a transaction. This is meant to honor nolock headers.
* Fixed hidden merge conflict
* Bugfix in aql-profiler.js: use plan.nodes order, not stats
* Added two profiler tests for filter
* Avoid too many getBlock calls in the FilterBlock
* Removed debug output
* RemoteBlock API will now send a done(bool) flag whenever we request documents from remote Servers. It is possible that we are DONE and have a result. The pre 3.4.0 API uses exhausted which is exclusive to a result. This API is still implemented for beckwards compatibility.
* Implemented an executeSync function in AqlQuery. This will block the thread until query execution is complete
* Added another test for FILTER, and one test for the HashedCollectBlock
* Added more tests for HashedCollectBlock; avoid unneccessary getSome calls
* Added an profiler IndexBlock test
* IndexBlock: avoid redundant getSome calls, added missing traceGetSomeEnd calls
* Added a second test profiling IndexBlock
* Added a third test for IndexBlock

* Fixed std::min calls I broke
* Let shutdown calls in AQL wait, if the query is executed successfully.
* Fixed queryResult going out of scope

* Revert "Suppress clang warnings"
This reverts commit 05591649c59743c992edd5e78814edc8ca2a83e0.
* Bugfix: cleanup state in RemoteBlock ::shutdown, ::getSome and ::skipSome
* Bugfix in Subquery shutdown: don't skip subquery shutdown when main query shutdown failed
* Allow copy elision
* fix some deadlocks found by evil lock manager (tm)
* fix duplicate lock
* fix indentation
* ensure proper lock dependencies
* fix lock acquisition
* removed useless comment
* do not lock twice
* create either a V8 transaction context or a standalone transaction context, depending on if we are called from within V8 or not
* AQL micro optimizations
* use explicit constructor
* only use V8DealerFeature's ConditionLocker for acquiring a free V8 context
entering and exiting the selected context is then done later on without having to hold the ConditionLocker
* remove some recursive locks
* Disable custom deadlock detection when Thread Sanitizer is enabled
* Changing ifdef's
* grr
* broke gcc
* Using atomic for ApplicationServer::_server
* fix premature unlock

* removed assertion
* some more bugfixes
* Fixing assert
(cherry picked from commit 1155df173bfb67303077fbe04ee8d909517bfd21)
* Switching from ttl to supervision based failover mechanism
* Allowing canceling of ongoing actions
* refactored asyncjobmanager
* refactoring some code
* adding read-only flag
* catching some exceptions to reduce log pollution, removing unnecessary code, removing tests for _changeMode
* fixing "createsANewDatabaseWithAnInvalidUser"
* auth = off does not longer make everyone superuser
* Fixing cluster_sync and maybe resilience
* 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.
* Testing hash for documents
* fixing logspam error
* added base support for kHash in the edge index
* Current version of hash enabled edge index
* removed rocksdb key type byte, dynamic prefixes for hash-index
* Fixing issues with key classes
