* Decoupled IO handling from Scheduler.
* Fixed SSL start up bug.
* Replaced Scheduler with new worker farm implementation.
* Added minimal statistics and info string for Scheduler.
* Added support for timed submissions.
* Updated delayed submission api. Updated code that used timers.
* Extracted new Scheduler into a virtual parent class. The implementation can now depend on the usecase.
* Signal handler now working.
* Changed threads names, `_stop` is atomic, check for failure during thread start + exception handling like old scheduler did.
* Commented on source code and added TODOs.
* Played around with start-stop-conditions
* Play around with start stop condition.
* start stop cond
* Sart Stop Conditions
* Removed bad cv_status check.
* Bug fix: now compare the actual objects instead of pointer values. Setup t1 and t2 depending on the thread id.
* Moved most of the stuff now unrelated to the Scheduler to GeneralServer. Got rid of JobGuard.
* Instead of waiting for a thread to terminate, put it on a clean up list and check for its termination in each supervisor run.
* Allow detaching long running threads.
* Fixed test mock.
* Updated the WorkHandle logic. Removed post functions.
* Fixed crash when obtaining shared_ptr from this in destructor.
* Added lost mutex.
* Fixed memory leak.
* Fixed merge bug.
* Changed a lot of code to optimize the scheduler.
* Fixed bug of invalidated iterator. Dont remove task on shutdown at different places. Let scheduler threads run until queue is empty.
* Only by value calls to queue.
* Added options again.
* Clean up of code.
* UI Request Lane added.
* Bug fixes in Scheduler.
* Applied reformat.
* Use sigaction.
* 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.
* Make isRestore work in the cluster.
This covers sharded collections with default sharding and non-default
sharding.
* always use locally generate revision ids for storing and looking up documents
* do not use V8 variant of AQL functions in early optimization stage when a C++ variant is available
* additionally, simplify AQL function definitions and aliases
* warn when more than 90% of max mappings are in use
* added C++ variant of replication catchup
* added `--log.role` option
* updated CHANGELOG
* removed non-existing scheduler.threads option from config
* removed useless __FILE__, __LINE__ invocations
* updated CHANGELOG
* allow a priority V8 context
* remove TRI_CORE_MEM_ZONE
* try to fix Windows errors & warnings
* cleanup
* removed memory zones altogether
* exclude system collections from collection tests
* added V8 context lifetime control options `--javascript.v8-contexts-max-invocations` and `--javascript.v8-contexts-max-age`
* make thread scheduling take into account most of the tasks dispatched via the io service
* fix buffer overruns in linenoise for long input lines
* don't make historian repeatedly print the same error messages that nothing can be done about
* make the implementations of the logging operator<<s not throw exceptions, so that logging does throw exceptions as an unintended side effect
* update CHANGELOG
* improve error message
* don't copy strings, but pass them by const reference
* reduce extractions to projections
* recycle string buffers in SocketTask
* micro optimizations for mmfiles indexes
* added special lookup function for _key
* moved function into the correct file
* speed up key buffer allocations a bit
* added noexcept specifier
* correctly name variable
* explicitly move bounds
* fix and speedup from/toPersistent functions
* reuse string from ManagedDocumentResult for multiple lookups
* use move-assign
* a bit less work for single server
* speedup AQL function HASH
* single fetch optimization
* performance optimization for the case when no documents need to be returned
* make reduce-extraction-to-projection a RocksDB-only optimizer rule
* cppcheck
* try to fix compile error on MacOS
* bug fix for MacOSX
* missing namespace (in Windows compile)
* Take out 503 timeouts altogether.
* Overhaul of AgencyComm::sendWithFailover loop.
* Let performRequests optionally ignore 404 coll not found.
* Fix error message "database not found" when AgencyComm failed.
* Add log entries in Agency if locks are acquired too slowly.
* Reexecute the javascript cluster sync stuff even if there was no plan/current change...So failed sync jobs can retry later...
* Cover callbacks in Communicator by lock. This fixes https://github.com/arangodb/planning/issues/370
* Put in delay in waiting for leader in agency test.
* Schmutz logging to heartbeat topic.
