* CORDA-3824: Add unit tests
* CORDA-3824: Fix property rename in AMQP object evolution
* Rename deserializedException to deserializedObject
* Rename test class to EvolutionObjectBuilderRenamedPropertyTests
* Added descriptions of the different object evolution stages in this test
* Rename file containing the serialized object
* Regenerate serialized data
* Add a comment explaining the commented out code.
* Restrict new behaviour to EvolutionObjectBuilder and simplify the loop that builds constructor slots.
We should not overwrite the stack trace of local errors thrown by
`FlowContinuation.Throw` as it hides the real cause of the error.
Exceptions received from peer nodes are still overwritten.
* CORDA-3960: Port MultiRPCClient to OS
* CORDA-3960: Carefully restore serialisation environment in `MultiRpcClientTest` to eliminate side effects on other tests
* CORDA-3960: Move ThreadDumpUtils.kt to `core-utils`
Flows that were started with a client id would hang because it would
retrieve the existing flow's future and wait for it to finish. But,
because the flow has failed its flow init and not saved its initial
checkpoint, it is relying on `startFlow` to start the flow again (by
redelivering the start flow external event).
`FlowWithClientIdStatus` now holds the flow id that it is related to.
This is then checked in `startFlow`. If a matching client id is found
for a flow start, it then checks the flow id as well. If the flow id
matches, then it lets the `startFlow` call continue, allowing it to
actually start the flow again (how a flow without a client id would
retry in this situation).
Previously we were just throwing this away when pausing, meaning
updates would not be passed back to the user.
The progress tracker is now maintained in the `NonResidentFlow`
allowing it to be reused in the flow when it is retried.
* ENT-5672 Update database query to get paused flows which have previously been hospitalised
* NOTICK Remove unneeded check if a database exception was removed when switching a flow to RUNNABLE since we were to remove it anyway
Always attempt to load a checkpoint from the database when a flow
retries.
This is to prevent transient errors where the checkpoint is committed to
the database but throws an error back to the node. When the node tries
to retry in this scenario, `isAnyCheckpointPersisted` is false, meaning
that it will try to insert when it tries to save its initial checkpoint
again.
By loading from the existing checkpoint, even though it doesn't
really use it because it is `Unstarted`, the flag gets put into the
right state and will update rather than insert later on.
The issue with the test was that the environment variable are kept as a static member so it passed if it was the first one to run, but failed if another test runs the config beforehand.
* Draft version of integrating start flow with client id with reconnecting rpc client
* Add recursive reconnect
* Execute 'doInvoke' on a different thread, fixes hanging
* Tidy up code and add explanatory comment
* Add test timeout
* Add test asserting 'removeClientId' does retry to connect if the node is down
* Modify test to not create a new node on node restart
* Add test asserting 'reattachFlowWithClientId' tries to reconnect if the node is down
* Add test asserting returned flow exception future continue working on node restart
* Add assertions for reconnecting future callbacks
* Remove unused import
* Remove unused local var
* Remove unneeded line breaks
* Remove unneeded parentheses
* Amend existing test; assert flow result reconnectable future returned from 'reattachFlowWithClientId' works
* Update test names
* Add explanatory comment
* Minor comment update
* Fix accidental methods moved
* Update obsolete comment
Terminate sessions that need to be removed instantly in whatever transition is currently executing, rather than scheduling another event and doing so at a later time.
To do this, update the transition being created in `TopLevelTransition` to remove the sessions and append the `RemoveSessionBindings` action to it.
This achieves the same outcome as the original code but does so with 1 less transition. Doing this also removes the race condition that can occur where another external event is added to the flow's event queue before the terminate event could be added.
* CORDA-3986 Increase sleep in `FlowSessionCloseTest`
A sleep duration needed to be increased to ensure that an end session
message has time to be processed by the other node.
Locks do not fully fix this because some internal processing needs to be
completed that can't be waited for using a lock. Therefore the sleep
time was increased generously.
* removed dependency from tools.jar
I removed the log line in /node/src/main/kotlin/net/corda/node/internal/NodeStartup.kt because I felt it was not so important
and I modified the checkpoint agent detection simply using a static field (I tested both with and without the checkpoint agent running and detection works correctly)
* move method to node-api to address review comments

* CORDA-3954: Added step to run database migration scripts during initial node registration with -s / --skip-schema-creation option (default to false) to prevent migration.
* CORDA-3954: Applied code convention to if statement
* CORDA-3954: Marked NodeCmdLineOptions' -s/--skip-schema-creation as deprecated and hidden in line with --initial-registration
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).

* 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 test which had dependency on the order int the result (failed for windows)
* 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.
