Disable `SignatureConstraintMigrationFromHashConstraintsTests.HashConstraint cannot be migrated to SignatureConstraint if a HashConstraint is specified for one state and another uses an AutomaticPlaceholderConstraint()` as it frequently appears in reports about Gradle process failures, to try isolating the actual cause.
* fix suggestion and tests
* detekt suppress
* making sure the forced join works with IndirectStatePersistable and removing unnecessary joinPredicates from parse with sorting
* remove joinPredicates and add tests
* rename sorting
* revert deleting joinPredicates and modify the force join to use `OR` instead of `AND`
* add system property switch
* CORDA-3657 Extract information from state machine
`FlowReadOperations` interface provides functions that extract
information about flows from the state machine manager.
`FlowOperator` implements this interface (along with another currenly
empty interface).
* CORDA-3657 Rename function and use set
* initial test is passing
* wip
* done tests
* additional tests to cover more FlowIORequest variations
* completed tests
* The quasar.jar should nat have been changed
* Fixed issues reported by detekt
* got rid of sync objects, instead relying on nodes being offline
* Added extra grouping test and minor simplification
* Hospital test must use online node which fails on otherside
* Added additional information required for the ENT
* Added tests to cover SEND FlowIORequests
* using node name constants from the core testing module
* Changed flow operator to the query pattern
* made query fields mutable to simply building query
* fixed detekt issue

* Fixed recommendations in PR
* Moved WrappedFlowExternalOperation and WrappedFlowExternalAsyncOperation to FlowExternalOperation.kt as per PR comment
* Moved extension to FlowAsyncOperation
* removed unnecessarily brackets

Fix memory leak due to DB not shutting down in FlowFrameworkPersistenceTests.flow restarted just after receiving payload.
Also reduces number of class-wide variables to reduce scope for references being accidentally held between runs.
`KillFlowTest` is failing quite often. This is probably due to issues in ordering when taking and releasing locks. By using `CountDownLatch` in places instead of `Semaphore`s should reduce the likelihood of tests failing.
* CORDA-3936: Add a fallback mechanism for Enums incorrectly serialised using their toString() method.
* Backport missing piece of Enum serializer from Corda 4.6.
If an error occurs when creating a transition (a.k.a anything inside of
`TopLevelTransition`) then resume the flow with the error that occurred.
This is needed, because the current code is swallowing all errors thrown
at this point and causing the flow to hang.
This change will allow better debugging of errors since the real error
will be thrown back to the flow and will get handled and logged by the
normal error code path.
Extra logging has been added to `processEventsUntilFlowIsResumed`, just
in case an exception gets thrown out of the normal code path. We do not
want this exception to be swallowed as it can make it impossible to
debug the original error.
Save the exception for flows that fail during session init when they are
kept for observation.
Change the exception tidy up logic to only update the flow's status if
the exception was removed.
Add `CordaRPCOps.reattachFlowWithClientId` to allow clients to reattach
to an existing flow by only providing a client id. This behaviour is the
same as calling `startFlowDynamicWithClientId` for an existing
`clientId`. Where it differs is `reattachFlowWithClientId` will return
`null` if there is no flow running or finished on the node with the same
client id.
Return `null` if record deleted from race-condition
Update the compatible flag in the DB if the flowstate cannot be deserialised.
The most common cause of this problem is if a CorDapp has been upgraded
without draining flows from the node.
`RUNNABLE` and `HOSPITALISED` flows are restored on node startup so
the flag is set for these then. The flag can also be set when a flow
retries for some reason (see retryFlowFromSafePoint) in this case the
problem has been caused by another reason.
Added a newpause event to the statemachine which returns an Abort
continuation and causes the flow to be moved into the Paused flow Map.
Flows can receive session messages whilst paused.
