* CORDA-3356 Subflow ledger consistency tests + move statemachine tests to slow integration tests
Add tests for subflows that fail during transitions.
Split out `StatemachineErrorHandlingTest` into a series of smaller tests.
Move these tests into the `integration-test-slow` category so they are
not run against every PR.
* CORDA-3356 Fix detekt issue
* CORDA-3356 Tidy test names
* Added a timestamp property to Checkpoint getting a new Instant.now() value at every Checkpoint instantiation/ copy instantiation. FlowMonitor is now using this new property (Checkpoint#timestamp) and StateMachineState#isFlowResumed to determine which flows are actually suspended. It leaves out flows that are doing work in their FlowLogic#call method.
* Cleaner comment
* Broke FlowMonitor#logFlowsWaitingForParty into logFlowsWaitingForParty and waitingFlowsToDurations. This way waitingFlowsToDurations is modular and can be tested.
Made FlowMonitor constructor get StateMachineManager instead of the retrieveFlows lamda. This way FlowMonitor is more consistent as a service, and entire flow filtering process is now being done in FlowMonitor#waitingFlowsToDurations.
Removed "smm as? StateMachineManagerInternal" in AbstractNode#start as it made no sense.
Updated CheckpointDumper to mention the Checkpoint#timestamp when writing the checkpoint as json.
* Added tests for FlowMonitor service.
* Remove old comment
* 1. FLowMonitor#waitingFlowDurations now returns a Sequence to have an iteration less.
It used to be, one iteration from returning a Set from FLowMonitor#waitingFlowDurations plus one iteration from FlowMonitor#logFlowsWaitingForParty.

* Quick and dirty change to stop "Unable to start notaries." error message (#5686)
"Unable to start notaries. A required port might be bound already" is
returned whenever a startup error occurs while starting the notary nodes
in driver tests. This hides the real error.
This change prints the actual error to std_err and read from file
at a later point. This means the real error is not lost and will be
shown in failed builds.
* Suppress detekt warnings
This is to potentially help with debugging in the future as the
`flowId` could become confusing for received messages where the `flowId`
has nothing to do with the current flow.

- Add method to `StaffedFlowHospital` that was missed during original merge
* CORDA-3194 Do not allow killed flows back into the hospital
This change has been made to prevent killed flows from being added back
to the hospital after being forcibly removed by `killFlow`. Not doing so,
could leave references to a flow inside of the hospital, which is not
the correct behaviour.
`killFlow` now sets a flow's `StatemachineState.isRemoved` to true.
This check is then used in `StaffedFlowHospital` and the
`DumpHistoryOnErrorInterceptor`.
* CORDA-3194 Log different message for transition error due to killed flow
When a flow is killed, its checkpoint is deleted. Currently, the
statemachine will still try a process the next event even if it has
been killed. This can lead to an error when trying to update the
deleted checkpoint. The exception thrown from this is logged out.
An if statement has been added to log a different message at debug level
if it is due to an update error for a killed flow. This is done to not
alarm node operators of the exception.
* CORDA-3194 Relax duplicate insert flow hospital handling
Revert a previous change to now make the duplicate insert staff member to
give a diagnosis of discharge or not my speciality (previously gave
terminal).
This is to prevent duplicate insert handling from overriding finality
flow error handling.
* added the warning as a TimerTask at StaffedFlowHospital#delayedDischargeTimer
* moved the scheduling of the warning task at StaffedFlowHospital#init block. That way we ensure that the task will be scheduled only once at StaffedFlowHospital initialization.
* Corrected overnight observation warning task's logging message. Changed StaffedFlowHospital#delayedDischargeTimer to the more generic StaffedFlowHospital#hospitalJobTimer since it now schedules delayed discharges tasks as well the overnight observation warning task. Removed this from property reference
* switching to fun timerTask for the instantiation of anonymous TimerTask classes
* Correct condition to log patients who are currently in the hospital, whose last record in their medical records is Outcome.OVERNIGHT_OBSERVATION. Extended logging to include treatableSessionInits staying in the hospital
* Add not empty check for patientsUnderOvernightObservation. Correct strings.
When a flow fails to retry, it should be kept in for overnight observation and aborted.
In the future, it might be possible to retry flows again that failed during their retry, but for now keeping for observation and aborting is satisfactory.
* CORDA-3194 Remove hospitalised flows from `HospitalisingInterceptor`
Small refactor to remove some of the hospital logic out of the
`HospitalisingInterceptor` and into the `StaffedFlowHospital`.
Add some comments to help clarify the purpose of the two maps inside
of the hospital.
* CORDA-3194 When a flow fails to retry force it into observation
When a flow fails to retry, it should be kept in for overnight
observation and aborted.
In the future, it might be possible to retry flows again that failed
during their retry, but for now keeping for observation and aborting is
satisfactory.
* CORDA-3194 Test for database commit failure when retrying a flow
Failing during the database commit failure that occurs after the retry
flow action does not stop the flow from actually retrying. This test
confirms this functionality.
The retried flow gets scheduled as part of the retry action. The failure
in the commit action does not prevent this since it has already been
scheduled.
* CORDA-3194 Replay start flow events when responding flow fails initial checkpoint commit
Logic has already been added to recover from initial checkpoint commit
failures on the initiating flow side but this did not suffice for
the same failure occurring on the responding flow's side.
The same idea has been added to resolve the responding flow's issue.
`ExternalMessageEvent` now has a `flowId` that is maintained on the
event. Messages can then be replayed to start/restart the flow, while
the event provides the flow id to each flow start.
Each `ExternalMessageEvent` implementation generates a random `flowId`
when constructed.
Events are stored in Artemis. This allows the solution to recover across
node restarts as the events will be pulled from artemis again when
restarting.
In the future `flowId`s will probably moved off of the events and
generated purely on the responding flow's node.
* CORDA-3194 Add test to verify that errors removing a responding flow are recoverable
* Unwrap rx.OnErrorNotImplementedException so the hospital can handle the cause appropriately
* Add db failure cordapp
* Renamed folders to avoid ambiguity in gradle
* Add integration test for exception hospitalisation when thrown from an RX observable.
* Make the test slightly cleaner
* Fix the schema to actually match the requirements for my custom state. Thanks a bunch, H2.
* Switch test to use SqlException base class.
* Schedule error event if we detect that a commit or db flush has thrown (forcing the flow to error even if customer code then goes ahead to swallow the exception)
* Revert change to schedule extra error
* Add more tests for edge case with DB exceptions, changed CorDapp to suppor this an hook in the flow hospital
* Warning about unsubscribe
Check state transitioned from clean to error for hospital admission.

* More tests for various error/catch combinations
* Clean up and comments
* Code reformat
* Fix test compilation
Wrap exceptions that occur in state machine transitions with a custom exception type which is
then handled inside of the flow hospital. As part of this change, a number of side negative side
effects have been addressed.
General summary:
- `StateTransitionException` wraps exceptions caught in `TransitionExecutorImpl`
- `StateTransitionExceptions` are handled in the flow hospital, retried 3 times and then kept in
for observation if errors persist (assuming conditions below are false)
- Exceptions that occur in `FlowAsyncOperation` events are wrapped in
`AsyncOperationTransitionException` and ignored by the flow hospital transition staff member
- `InterruptException`s are given a `TERMINAL` diagnosis by the flow hospital transition staff
member (can occur due to `killFlow`)
- Allow flows which have not persisted their original checkpoint to still retry by replaying their
start flow messages
- Swallow exceptions in `AcknowledgeMessages` actions
Detailed summary:
* CORDA-3194 Add state machine transition error handling to flow hospital
Wrap exceptions that are caught in `TransitionExecutorImpl` (coming from
new errors) with `StateTransitionException`. This exception is then
handled explicitly by the flow hospital.
Add `TransitionErrorGeneralPractitioner` to `StaffedFlowHospital`. This
staff member handles errors that mention `StateTransitionException`.
Errors are retried and then kept in the hospital if the errors persist.
* CORDA-3194 Remove a fiber from the `hospitalisedFlows` if its previous state was clean
If the fiber's previous state was clean then remove it from
`HospitalisingInterceptor.hospitalisedFlows`. This allows flows that are
being retried to clean themselves. Doing this allows them to re-enter
the flow hospital after executing the fiber's transition (if an error
occurs).
This is important for retrying a flow that has errored during a
transition.
* CORDA-3194 Set `isAnyCheckpointPersisted` to true when retrying a flow
Added to prevent a single flow from creating multiple checkpoints when
a failure occurs during `Action.AcknowledgeMessages`.
More specifically, to `isAnyCheckpointPersisted` is false when retrying
the flow, even though a checkpoint has actually been saved. Due to this
a brand new flow is started with a new flow id (causing duplication).
Setting `isAnyCheckpointPersisted` to true specifically when retrying a
flow resolves this issue.
* CORDA-3194 Add Byteman test to verify transition error handling
Add `StatemachineErrorHandlingTest` to verify transition error handling.
Byteman allows exceptions to be injected at certain points in the code's
execution. Therefore exceptions can be thrown when needed inside of the
state machine.
The current tests check errors in events:
- `InitiateFlow`
- `AcknowledgeMessages`
* CORDA-3194 Swallow all exceptions in `ActionExecutorImpl.executeAcknowledgeMessages`
Swallow the exceptions that occur in the `DeduplicationHandler`s when
inside of `ActionExecutorImpl.executeAcknowledgeMessages`.
The side effects of the failures that can happen in the handlers are
not serious enough to put the transition into a failure state.
Therefore they are now caught. This allows the transition to continue
as normal, even if an error occurs in one any of the handlers.
* CORDA-3194 Wrap unexpected exceptions thrown in async operation transitions
Exceptions thrown inside of `FlowAsyncOperation.execute` implementations
that are not returned as part of the future, are caught, wrapped and
rethrown. This prevents unexpected exceptions thrown by (most likely)
user code from being handled by the hospital by the transition
staff member.
This handling might change moving forward, but it allows the async
operation to continue working as it was before transition error handling
was added.
* CORDA-3194 Verify that errors inside of `AcknowledgeMessages` work as expected
Update `StatemachineErrorHandlingTest` to correctly test errors that
occur when executing the `AcknowledgeMessages` action.
* CORDA-3194 Retry flows that failed to persist their original checkpoint
Allow a flow that failed when creating their original checkpoint (for
example - failing to commit the db transaction) to retry.
The flow will create a brand new checkpoint (as the original did not
saved).
This required adding `flowId` to `ExternalStartFlowEvent` to allow the
event to keep a record of the flow's id. When the flow is retried, the
events are replayed which trigger a flow to be started that has the
id stored in the event.
To allow this change, code was removed from `retryFlowFromSafePoint` to
allow the function to continue, even if no checkpoint matches the passed
in flow id.
* CORDA-3194 Correct `FlowFrameworkTests` test due to error handling
Test assumed that errors in transitions are not retried, this has now
been updated so the test passes with the flow succeeding after an
exception is thrown.
* CORDA-3194 Remove unneeded import
* CORDA-3194 Make the state transition exceptions extend `CordaException`
`StateTransitionException` and `AsyncOperationTransitionException` now
extend `CordaException` instead of `Exception`.
* CORDA-3194 Improve log messages
* CORDA-3194 Remove unneeded code in `HospitalisingInterceptor`
Due to a previous change, a section of code that removes a flow id
from the `hospitalisedFlows` map is no longer required. This code has
been removed.
* CORDA-3194 Constraint violations are given `TERMINAL` diagnosis
Add `Diagnosis.TERMINAL` to `StaffedFlowHospital` to allow an error
to be ignored and left to die a quick and painful death.
`StateTransitionException` changed so it does not cause serialisation
errors when propagated from a flow.

NotaryFlow.Client flow assumes the passed transaction is verified, which is
the case when it's invoked as a sub-flow in FinalityFlow. However,
NotaryFlow.Client can also be called directly from any custom flow, so
we need to ensure it performs transaction verification to avoid accidentally
sending an invalid transaction to a non-validating notary.

- fixed unit tests.
- added comment to changelog.rst.
- added helper functions to `StatePointer` to allow easier creation of static and linear pointers.
Allow node operators to blacklist signing keys (using blacklistedAttachmentSigningKeys config option). These blacklisted keys prevent attachments that are received over the network from being trusted. The docs have been updated to detail how to generate the key hashes that the config requires.
A new shell command attachments trustRoots has been added to see what attachments exist on the node along with information about their trust and where it comes from.
run dumpCheckpoints has been replaced by checkpoints dump as InternalCordaRPCOps needed to change to prevent a function that is meant to be internal from being visible on the shell.

- Handle errors in Jackson and checkpoint deserialisation. A file
notifying the user that the checkpoint dump failed is created when
errors occur.
- Handle message deserialisation errors. A string placeholder is used
if an error occurs.
- Add more information about subflows (include their `FlowLogic`)
- Increase clarity in checkpoint output field names
* CORDA-3904 Add `flowCallStackSummary`
Add `flowCallStackSummary` to the output which contains the same content
as `flowCallStack` minus each subflow's `FlowLogic`. The `FlowLogic`
contains a ton of info which is normally repeated in each subflow.
Adding the summary gives an overview of the steps the flow executed
and which step it is currently on.
The `suspendedOn` field is put underneath the summary and the original
call stack is moved below the suspended info.
This puts the most useful information towards the top of the json file.
* CORDA-3018 Allow loading an untrusted contract jar if another attachment exists that was signed with the same keys and uploaded by a trusted uploader
`TransactionUtils.isAttachmentTrusted` requirements have been relaxed
to allow an untrusted attachment to be loaded as long as another
attachment exists that is signed by the same keys and was uploaded
by a trusted uploader.
The requirement of containing the same contract classes has been
removed. Therefore the contents of the existing trusted attachment
no longer matters.
* CORDA-3018 Allow a subset/intersection of signers in `isAttachmentTrusted`
Allow a subset/intersection of signers to satisfy the signer
requirements of `isAttachmentTrusted`. This allows an "untrusted"
attachment that is signed by one or more keys to be "trusted" as long
as another trusted attachment already exists that is signed by at least
one of the "untrusted" attachments signers.
A cache of trusted and untrusted public keys is now held (replacing the
previous cache of `List<PublicKey>`.
Tests have been added to `NodeAttachmentServiceTest` to confirm that
an attachment query using an `EQUAL` statement will actually return
attachments that are signed by any of the keys passed into the query.
Confirming this allowed an `EQUAL` query to satisfy the search that
had to be done as part of this change.
`MockAttachmentStorage`'s query criteria was updated to better match
the real `NodeAttachmentService` implementation.
* CORDA-3018 Update cache name and kdoc on `isAttachmentTrusted`
* CORDA-3018 Verify that chains of trust do not occur
* CORDA-3018 Switch keys around to improve chain of trust tests
* [ENT-3801] Store transactions in the database during transaction resolution (#2305)
* ENT-3801: Store downloaded txns as part of the backchain resolution into the db rather than the checkpoint
It's very inefficient to store the downloaded backchain in the checkpoint as more of it downloaded. Instead, if a threshold is reached (which currently defaults at 0) then the backchain is stored in the transactions table as unverified. A new is_verified column has been added to track this. Initially testing on the OS codebase has been very promising but unfortunately this current code is not quite ready. I had to quickly port it to ENT as this is meant to be an ENT-only optimisation.
To that effect, there is a TransactionResolver abstraction with two implementations: an in-memory one which has the old behaviour, and which will be the behaviour for OS, and a db one.
DBTransactionStorage hasn't been fully updated and I had to comment out the optimistic path for now.
Most of these changes will need to be ported to OS to keep the merge conflicts in check, but obviously not DbTransactionsResolver and the "is_verified" changes in DBTransactionStorage. DBTransactionStorage does have other refactoring which will make sense to port though.

Change to `SingleThreadedStateMachineManager`.
Instead of throwing an exception when a flow's fiber cannot be found,
just log the message at info level.
(cherry picked from commit 70b2a94fda)
Allow Hash Constraints to propagate to Signature Constraints. When
propagating, the new jar is added to the transaction instead of the
original contract attachment (jar).
The following requirements must be met to do so:
- System property "net.corda.node.disableHashConstraints" must be set
to `true`
- The min platform version must be 4 or greater
- There must be an input state with a hash constraint
- There must be no output states with a hash constraint
- The new jar must be signed
If these requirements are not met, the original Hash
Constraint will be kept and the contract attachment related to it is
also used.
This transition is done at the start of `handleContract` as it is not
the normal path a transition would follow. It is considered a backdoor
and should be treated separately from the rest of the attachment and
constraint logic. Furthermore, it will only work in private network
since all nodes must set the special `disableHashConstraints` flag.
* Fix test execution flakiness on fast hardware: set node info polling interval to 1 second in DriverDSL Node Startup (was only being set to 1 sec in Node Registration). Follow-up to https://github.com/corda/corda/pull/5240
* Diagnostics: add additional logging to NodeInfoFilersCopier.
* Diagnostics: add additional logging to NodeInfoWatcher
* Downgrade logging level severity to debug.
* Make atomic counter unique across instances.
Change to `SingleThreadedStateMachineManager`.
Instead of throwing an exception when a flow's fiber cannot be found,
just log the message at info level.
When set to true the RPC client will:
* automatically reconnect when the connection is broken
* simple RPC calls will block until connection is established
* Observables returned from RPC will automatically resubscribe on reconnect so the client continues to receive events. This doesn't guarantee that events will not be lost during the reconnect.
As a general purpose API, allPersisted should not be loading the entire contents of the database table into memory. Instead now it returns a Stream for processing of elements.

Which after discussion with @dimosr and @fowlerrr proven to be contradictory.
Dumps all the node's checkpoints as JSON into a single zip file in the node's directory. The output contains:
* All the fields for the top-level flow
* The current sub-flow call stack, along with the current progress tracker step for each sub-flow
* The event that suspended the flow, which if it's a send or sendAndReceive will show the payload that was sent
* Low level information on the active sessions with other peers
* Initial commit with a test that can detect a logger that isn't initialised with by lazy that gets called during startup.
* Test improvement. Test fix for api stability.
* Added explanatory comment for the test.
* Changes according to PR review. Added empty file check to make test more robust.
Party and AnonymousParty have been retrofitted to implement this interface and are currently the only supported types. A new FlowLogic.initiateFlow(Destination) method overload to easily support the addition of new destination types in future versions.
To prevent making `dumpCheckpoints` part of the public API a new
interface, `InternalCordaRPCOps` has been created and the function
has been moved there. `InternalCordaRPCOps` inherits from
`CordaRPCOps`.
`CordaRPCOpsImpl` now implements `InternalCordaRPCOps`.
`RunShellCommand` and `StringToMethodCallParser` required additional
changes due to issues handling inherited functions. This has only been
raised now due to `InternalCordaRPCOps` inheriting from `CordaRPCOps`.
Many classes have had references to `CordaRPCOps` changed to
`InternalCordaRPCOps`.
