* Consolidated _servers and _serverAdvertisedEndpoints, added rebootId, prepared change notifications
* Cleanup
* Added a RebootId type
* Began implementing RebootTracker (still WIP)
* Moved RebootId operators into the class
* Removed RebootId operator<< again
* Added tests, added CallbackGuard, removed/commented old RebootTracker code
* Fix: do not try to call unset callbacks
* Split one test, added another
* Added more tests
* Renamed tests, added more tests
* Fixed missing variable declarations
* Let MockServer appear to be started
* Reorded test, fixed naming
* Implemented callMeOnChange()
* Re-implemented RebootTracker (not yet working)
* Resolved a TODO, updated a test, added comments
* Call old callbacks immediately
* Fixed tests
* Use EXPECT_* instead of ASSERT_*
* Suppress a log message
* Resolved TODOs
* Reverted changes on reading ServersRegistered
* Update RebootTracker
* Introduce `rebootId` into ServerState for Cluster
* A server *boots* if it is started on a previously non-existing data
directory and hence does not have a UUID yet.
* A server *reboots* if it is started on a pre-existing data directory
We keep the rebootId in the cluster's agency under
Current/ServersKnown/$uuid/rebootId.
When rebooting (and subsequently re-joining a cluster), the server increments
its rebootId in Phase 2 of registration. This way it can be detected within the
cluster whether a server was restarted.
This information will later be used to handle cases where server restarts can
lead to problems, for example with transactions or in-progress queries.
* Move rebootId into Current/ServersKnown/
* Fixed typo
* Fixed log ids
* Add deletion of ServersKnown/UUID from agency
* Add deletion of Current/ServersKnown/UUID to removeServer
* Clean up readRebootIdFromAgency and add retry loop around it
* Bugfix
* Added nolint comments
* Fixed initialization order
* Fixed ClusterInfo-test
* Added log messages
* Revert "Fixed ClusterInfo-test"
This reverts commit d983596979.
* Disabled assertion for google tests
* Ignore windows compile warning
* Always call loadServers in loadCurrent
* Fix really subtle bug when not returning a value
* Introduce `rebootId` into ServerState for Cluster
* A server *boots* if it is started on a previously non-existing data
directory and hence does not have a UUID yet.
* A server *reboots* if it is started on a pre-existing data directory

* Move rebootId into Current/ServersKnown/
* Add deletion of ServersKnown/UUID from agency
* Add deletion of Current/ServersKnown/UUID to removeServer
* Clean up readRebootIdFromAgency and add retry loop around it
* Fixed compile error due to forbidden implicit cast
* Fixed compile error on windows
* Fixed compile error due to devel merge
* Removed dead comment
* Removed TODO note
* Extended comment
* Removed TODO note
* Fixed using an invalidated iterator
* Copy string only if necessary
* Fixed compile error
* initial checkin of isRetryOK(). Includes fixes to known code that has previously hung shutdowns by performing infinite retries.
* slight help on getting out of a loop faster during shutdown. not essential.
* Added feature phases
* BasicsPhase and DatabasePhase to the required files. Server now has Feature circles and does not boot. Will be sorted out later on.
* Added ClusterPhase to features
* Added V8Phase to the required features
* Added AQLPhase to the affected features
* Added ServerPhase to Features
* Added FoxxPhase to the relevant features
* Added AgencyPhase to the relevant features
* Moved registration from local variable SYS_SYSTEM_REPLICATION_FACTOR from cluster to V8 as their ordering is now vice versa
* Moved Bootstrap feature into FoxxPhase. It could be moved to ServerPhase easily if the FoxxQueue dependency would be removed
* Final movement of Startup Phases. Now solved all circles.
* Removed merge conflict
* Moved ReplicationTimeout into cluster phase and fixed cross-phase requirements
* Added greetings phase. This phase separates the Basics Phase and is the first to be run. Includes Logger and Hello/Goodbye
* Added the GreetingsPhase in the corresponding features. Now all BasicsPhase features start after greetings Phase. There is some issue in this branch which prevents the Agency from Gossipping right now. Will be fixed next
* Moved creation of the Agent into the prepare phase of the feature. THereby it is guaranteed that agents at least exists before the GeneralServer is activating endpoints
* Recovery needs to be started after the ServerID
* Moved log output of FeaturePhases to DEBUG instead of ERROR.
* Added feature phases for clients
* ClusterFeature now does not directly require AgencyFeature any more
* Added requirement of TravEngineRegistryFeature in AQL feature. Otherwise shutdown may be undefined
* The ApplicationServer can now handout the list of ordered features. Used for testing purposes
* Fixed IResearchVew Tests Setup to honor new feature ordering
* Fixed IResearchViewDBServer Tests Setup to honor new feature ordering
* Started fixing IResearchView Coordinator tests with startup ordering. Not finished yet
* Added startup phases to ViewCoordinator test
* Disabled expected logoutput in ClusterRepairsTest
* Fixed indention in test code
* LinkCoordinator now honors startup ordering
* Link meta now honors startup rdering
* Supress expected cluster logs in ViewTest
* Removed '#' accidentially added.
* 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
* some more bugfixes
* Fixing assert
(cherry picked from commit 1155df173bfb67303077fbe04ee8d909517bfd21)
* do not rely on non-existing feature "AQL"
using such feature makes the server throw two exceptions (which will be caught) on startup, but its silly for debugging
* use condition variable for signalling shutdown
* do not hard-code the log levels for recovery tests
this has taken so many developers so much of their time that it is about time to fix it
* ensure the 'unittests' script properly finds 'arangosh' and the build directory
