* odd fix

* Bug fix 3.4/sync repl release thread (#6784)

* First attempt to not block the thread that requires the EXCLUSIVE sync-up lock

* Fixed insertion of query into registry in rest replication handler.

* Removed unnecessary / false asserts as suggested in review. Fixed code comments.

* Replaced auto with a correct type as suggested in review

* Added a helper function to validate if a query is in use in the registry

* Fixed logic bug in usage of query registry

* Fixed compile issue

* Automaticly transfrom int -> bool in initializerlist sucks...

* Inverted boolen logic bug hidden due to int->bool beeing logically inverted.

* Today it seems that bools are too complicated for my brain.

* Applied chenges required by @goedderz in review

* Bug fix 3.4/shorter foot in door (#7084)

* Implement `syncCollectionCatchup` in DatabaseTailingSyncer.

First stab, might not even compile.

* Further compilation fix.

* Implement two stage catchup.

* Two small corrections.

* Unified error messages in Synchronize shard job.

Tobias Gödderz fc3e11dbbc Async AQL (#5806)
* 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.

* Removed all references to OLD implementations in AQL. only the base wrappers are allowed to call OLD functions from now on. Now the testing part starts

* 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.

* Added IndexBlock::skipSome and IndexBlock::getSome

* getBlock now returns its old return value along with the state

* Switch from getBlockOld to getBlock in IndexBlock::skipSome

* Switch from getBlockOld to getBlock in IndexBlock::getSome

* First steps to adapt ClusterNodes to Async AQL api. Not there yet, need to implement the core still

* Added asnyc implementation for xxxForShard in ClusterBlocks. This commit changes internal logic of _doneForShard. Needs additional testing as soon as everything is in place.

* Adapted CalculationBlock to async API

* Adapted TraversalBlocks to ASYNC Aql. This is not optimal yet, we need a better decission if we are DONE or not on RETURN

* Adapted EnumerateListBlock to Async AQL api

* Adapted RemoteBlock to ASYNC API in getSome/skipSome. The whole thing is now LIVE in the cluster. Exetensive testing to be started now

* Fixed IndexBlock WAITING behaviour if Waiting occurs during a index processing

* Adapted IReasearchViewBlock to ASYNC AQL API

* Fixed SortingGatherBlock in WAITING state.

* 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

* Implemented dump and dumpSync in Cursors, Sync will block a thread, dump allows to wait, only relevant for Streaming cursor

* 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

* Moved general code to module

* Moved noncluster tests into a separate file

* Split aql-profiler testsuite into three files

* Added profiler tests for LimitBlock

* Added a test for NoResultsBlock

* Added profiler tests for TraversalBlock

* Shutdown of an AQL query is now asynchronous. However in Error-Cases it will be executed in a blocking way still

* Optimized TraversalBlock getSome calls due to new (nightly) test results

* Fixed std::min calls I broke

* Let shutdown calls in AQL wait, if the query is executed successfully.

* Fixed queryResult going out of scope

* fix compile error through merge conflict with devel

* Fixed compiler warning "mismatching tags"

* Removed debug log output

* Suppress clang warnings

* Bugfix: use of invalid stack pointer

* Bugfix: RemoteBlock::shutdown now sends code as int, not string

* 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

Jan 349e2c1681 forward-port AQL optimizations from 3.3 (#5020)
* forward-port AQL optimizations from 3.3

* fix restrict-to-single-shard rule

* added tests for specific cases

* ModificationNodes now can know if they are restricted or not

* OptimizerRule now updates the ModificationNode instead of setting ownName on remote node.

* The DBServerEngine container now only sends a subset of snippets (those which are relevant) It is  able to restrict any part of the query to a certain shard or even a list of shards

* ExecutionEngine CreateBlocks in ClusterMode now returns Result instead of throwing.

* Adapted Coordinator side to a bitter mapping of RemoteNode => QuerySnippets. This is still ongoing work.

* Fixed Coordinator enginecontainer test and finisehd implementation of EngineInfoContainerDBServer. Seems to work so far, need to adapt test to prove it.

* Adapted test for modification nodes and restrict to shard.

Feature/aql server based locking (#4783)
* 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
