Reformat
Fix non-babies remove and modify replication
* Remove some changes introduced by the merge
* Fixed compile errors introduced by merge
* Started Implementing the ServerBasedlocking. There now is a container that can contain multiple query snippets. It now has to setup the necessary calls to the Servers
* Added backwards linking of QueryEngines, sth. DBServers can contact their Coordinators.
* Added LogTopic AQL
* Made AccessMode::Type Hashable
* Created a Mapping Server => LockLevel => Shard and createad a JSON object containing the Lock information for a complete AQL query per server
* Added code to build coordinator engines
* Finished with first draft of Coordinator-side of new DBServer based locking.
* Added a _api/aql/setup route that creates and locks all snippets/collections for one DBServer in a single go
* Fixed some Coordinator parts
* Index node now gracefully reports if it could not find it's collection when created from vpack. Otherwise it just hardly crashed...
* Modified the Coordinator Snippet collector to be able to handle subqueries properly.
* Started adding GraphNode handling. WIP. Need to deploy engines properly. Coordinator crashes on Graph tests
* Fixed compiler errors
* WIP: EngineInfoContainer
* Separated the EngineInfoContainers for Coordinator and DBServer into different files. They diverged more than anticipated
* Added forgotten files. THe DBServer container now creates the TraverserEngine Mapping and moves it into the Infos. They are not keeping it yet and need to add it to the message as well.
* The DBServer engine infos now persist the TraverserEngine infos. Need to add them to messages though.
* The new aql exec-engine now sends out traverserEngines as well
* Formatting and adding DEBUG level output
* Made the RestAQLHandler aware of the TraverserEngineRegistry. Also created the engines now. Return format changed server-side coordinator side needs fix.
* Adapted the Coordinator side for the DBServer based Shard Locking
* The DBServer based Locking now honors restrictions to certain shards
* Fixed a strange double lock bug in the new AQL Server based locking technique. Add some DEBUG output
* Fixed usage of MAINTAINERMODE macro. The assertion was never active
* Added TestCase for ContainerCoordinatorTest to cmake
* Added -DTEST_VIRTUAL to CMAKE. This is used to define virtual functions for mocking ONLY on test-builds.
* Fixed usage of ENABLE_MAINTAINER_MODE ifdef. CLANG format
* On non-enterprise builds ENTERPRISE_VERT defaults to TEST_VIRTUAL => virtual in test else non-virtual
* Added TEST_VIRTUAL to ExecutionEngine, Query and QueryRegistry
* Added first testcase for EngineInfoContainerCoordinator not yet ready.
* Mode CreateBlock a member function of engine, we have the engine in our hands anyways no need to make it static. Included some more TEST_VIRTUAL functions.
* Fixed clang/MacOs compile error. Added some more TEST_VIRTUAL declarations
* Finally fixed the first buildEngines UnitTest \o/
* Added a unit-test for backward linking of dependencies in CoordinatorPlanner
* Added multi-snippet test for EngineInfoContainerCoordinator
* Removed QueryRegistry.h from central header files and replaced by a forward declartion.
* Added a createBlocks method on the ExecutionEngine. It should be responsible to create all those blocks at once. Adapted the UnitTests as well. Not included Tests for the new createBlocks functionality. Need to mock the options feature first
* Added another test that Coordinator Snippets of queries can be created correctly
* Fixed Coordinator-site cleanup of QueryRegistry, if any of the query creations fails with error, incl UnitTest.
* Added first test for RestAqlHandler::setup. It does only test the setup and gives prepartion for real testing.
* Added a assertion of http return code. Still no creation of queries is tested. Requires a huge amount of mocking.
* 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
* add some asserts
* honor collection locking in cluster
* yet one more lock fix
* removed assertion
* Allow the clustercomm to send nolock headers on count. This is used form within AQL
* IsLocked on transactions will now always yield true IF LOCK_NEVER is set. We simply assume someone else holds the lock for us. Also LOCK_NEVER is now set on collection/count if noLock header is send.
* Moved the flag if collections need to be locked into the TraverserEngines.
* Added enterprise-satellite hooks in EngineInfoContainerDBServer
* Removed now obsolete code
* Replaced throwing of Exception by an ResultObject
* Added some more tests and moved adding snippet to query engine more to the outside.
* Added the AQL result type
* Make the branch compile again
* Register WITH collections for Graphs in the new Collector.
* Fixed test code for failing query clone. Idea was to once clone successfully and second time to fail, we verify that first clone is cleaned up properly. However test failed on first clone...
* Removed a double builderClose
* Added Changelog entry
* Removed empty if
* Removed obsolete todo
* Properly initialize the AqlResult with nullptr on error case
* Updated comment
* Simplified Assertion
* Removed debug output object...
* Added additional catch case for std::exception to get some more error info
* Clarified evaluation order for move case
* Added Explicit
* Fixed cleanup of Coordinator if Registry fails to insert query.
* Allow to use other locks than Read/Write for AQL collections. Not yet in API.
* Updated Comments for other Locks on DBSide. Adapted Destruction CatchTests
* Fixed double builderClose and removed unnecessary double commits
* Added a comment to clarify the state
* Moved error output to trace. Leftover from debugging
* Added some tests for complex subquery patterns
* Added a 'fireAndForgetRequests' methods to cluster comm which allows to send out a bunch of messages but does not wait for their results
* Properly cleanup leftovers of queries if the instantiation step already failed
* Added code comment for fireAndForget
* Added indexes to subquery test to make the plan a bit easier
* The cleanup on DBServerEngines in error case now also cleans up traverser engines.
* Removed unnecessary includes
* Removed debug logging
* Fixed hidden merge conflict
* fix some deadlocks found by evil lock manager (tm)
* fix duplicate lock
* fix indentation
* ensure proper lock dependencies
* fix lock acquisition
* removed useless comment

(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
