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.

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run dumpCheckpoints has been replaced by checkpoints dump as InternalCordaRPCOps needed to change to prevent a function that is meant to be internal from being visible on the shell.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.

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`.

A test was failing due to `assumeFalse` (to stop a test running on windows)
being inside of a `assertThatExceptionOfType` block. The exception it
threw was consumed by the block instead of junit.
If a single whitelisted constraint is being used by input states and the version of the cordapp changes + is signed, then the constraint will transition to a signature constraint.
When a `UnexpectedFlowEndException` or a `FlowException` is received the
peer that the exception was thrown from will be added to the stacktrace.

`ExceptionSerialisingRpcOpsProxy` was removing information about the
original exception in dev mode. This code has been removed. Although
there is no check in `ExceptionSerialisingRpcOpsProxy` for dev mode
(and also due to it being about serialising),
`ExceptionMaskingRpcOpsProxy` will handle the removal of exception data
in non dev mode (production mode).

Addressed review comments - removed nested if and added parameter name for the usage of requiresCertificates.
Removed unnecessary import and white space.
Normally, these requests are left unacknowledged in the MQ broker to allow recovery via installing the missing CorDapp. If this is not applicable then the request be dropped (and the other side informed of the error).
While the node is starting up, we now check for the presence of the certificates directory. This allows us to print out an easily understandable error message if the directory is not present. An exception is made for devMode, as devMode will result in the directory being created in any case.
* ENT-3057: Log hibernate warns and errors in different log
If a hibernate error occurs (deadlock, for example) that would cause a flow to be sent to the hospital, hibernate logs the warnings and errors before we do. This results in duplication in the logs, and pollutes the log. To solve this, we create a new log appender named diagnostic-{node-name}.log and log any org.hibernate messages of warn and above to that file. This way, messages are not lost, which means that the information can be retrieved if need be.
* Corrected indentation of comment (changed tab to space)
* Updated node-administration document to mention diagnostic logging change
* Fixed integration test. It was breaking because it was fetching the first log file in the folder, assuming there would be only one. This assumption is now invalid because the diagnostic log file that was introduced. Two tests were found that used similar logic to find a log file to examine, hence both were corrected to look for log files beginning with "node"
* Updated documentation as per review comments.
Add a cache for notary identities in the PersistentIdentityService. This
solves a reported problem where notary identity lookup fails if its network
map entry is missing, which results in an exception when trying to insert
a state into the vault after recording a transaction.
Test if we have access to the logging path (baseDirectory/logs) before attempting to write to them. This allows us to shut down gracefully with an easily understandable error message.
Without doing this, the log4j2 will attempt to access the logPath when it first uses the logger in the call() function.
* CORDA-2629: Provide a better error msg when notary type misconfig
If a notary service is misconfigured with the type (either validating or not validating) stored in the node's configuration not matching that advertised in the network map cache, the notary will throw an exception and fail on startup.
Previously, this misconfiguration would result in an exception being thrown when attempting to notarise a transaction. This change results in the exception being thrown at node startup and the node operator being aware of the misconfiguration earlier.
* Corrected exception message when the notary does not have a party
* Changed exception message to include configured and advertised values.
Fixed unit test that was failing because of the new check.
* Plumb through the crlCheckSoftFail configuration option to bridge manager
* Add crlCheckSoftFail test to bridge manager and fix equivalent proton wrapper test
* Update documentation and set the node configuration default to true
* Revert default change and clarify consequences of setting option to false
* Remove NodeConfiguration default to leave only AMQPConfiguration default
There's a bug with the ServiceLoader which leaks a file handle to the app jar on shutdown. This causes an issue if a mock node is restarted in Windows. To avoid the problem completely we no longer overwrite any existing jars, as the jar to be copied will be same anyway.
(cherry picked from commit 0038a86481)
Only log a line about looking for notary implementations if at least notary implementation is found.
It might be unnecessary and confusing to log when no implementations are found.
Replaced TrustedAuthorityNotaryService with SinglePartyNotaryService in comment
* CORDA-2665: Updated OwnableState relevancy check is now gated on target version 4
https://github.com/corda/corda/pull/3789 changed the relevancy check of OwnableState to include the participants list in addition to the owner. This however breaks existing apps which assume (in their vault query) an OwnableState is recorded to the vault if-and-only-if the owner matches.
* CORDA-2665 Don't switch to new behaviour on target version upgrade.
When an RPC client disconnects from the RPC server, the log entry created now has its log level set to info rather than warning. It is perfectly normal for an RPC client to disconnect - only the RPC client knows if it was intentional.
* CORDA-2669 - pendingFlowsCount not in public API
Reintroduce `pendingFlowsCount` to public API (as deprecated). Advise
to use the `gracefulShutdown` command in the shell instead.
* CORDA-2669 - Add pendingFlowsCount to api-current.txt
* ENT-3053 Database connection pools leaking memory on every checkpoint. Flip in the thread local from the thread into the fiber.
* Back port to OS (needs some gradle changes) and added TODO, ability for it to avoid erroring if not using Hikari.
* Review feedback to remove warning.
* CORDA-2634 - Fix default currentTargetVersion
* CORDA-2634 - Include abstract flow classes in CorDapp class scanning
* CORDA-2634 - Run test for target platform version 4
To allow rolling upgrades where members of a BN may not all upgrade at the same time, the FinalityHandler is now always enabled, and not disabled if no old apps are installed.
Previously any attempt to use the FinalityHandler in such a scenerio would send the flow to the hospital, where manual intervention would be required to recover the transaction.

CORDA-2595 address code review comments
* First pass at fixing 2563.
* In memory KMS now maps keys to IDs.
* CreateDatabaseAndMockServices now creates a persistent key management service and a can take a persistent identity service, so now the external id mapping works for mock services.
* * Created a helper for mock services which allows the creation of a mock services with persistent identity management service key management service and vault.
* MockNode now uses persistent key management service - not sure why it didn't do before?
* * MockNode now uses BasicHSMKeyManagementService
* Updated api-current file
* Little fix required after rebase to master.
* Fixed broken test.
* Added informative error messages to UnsupportedOperationExceptions thrown by E2ETestKeyManagementService.
* Removed redundant private constructor for mock services from api-current.txt.
* Addressed Rick's comments.
* Create a new custom migration for populating the state_party table and the relevancy_status column within the vault_states table when migrating from V3 to V4.
* Add a corresponding unit test suite.
* Small refactorings to expose data required by the migration: the isRelevant function in the NodeVaultService, and the node's legal name from the configuration.
Previous implementation was in LedgerTransaction and focused only on contract classes,
but every package matters.
Also fixes some exception types and does misc refactorings.
Take out a useless parameter from a method that was added to the public
API, document it. Add some comments explaining more about why we are
looking up attachment versions in WireTransaction.toLedgerTransaction.
* CORDA-2547: WIP Migrate old notary schema correctly.
Modify liquibase scripts to rename the old committed state table instead of creating a new one.
* Rename liquibase change sets
* Change 3.3 baseline before Liquibase.
* Aligin with ENT, orginal node-notary.changelog-v1.xml moved to node-notary.changelog-v2.xml and it's compatible with ENT (which already has changes from v2).
* Aligin with ENT, orginal node-notary.changelog-v1.xml moved to node-notary.changelog-v2.xml and it's compatible with ENT (which already has changes from v2) - adding v2 to master file.
* Ensure setting up Liquibase on pre-existing pre-Liquibase database
* Add FetchParametersFlow
* No downgrade parameters in ResolveTransactionsFlow
Make sure that parameters in the transaction
graph are ordered (this is to prevent the downgrade attack, when the
malicious notary and participants sign transaction that shouldn't be
notarised otherwise). We ensure that by checking that epochs of network
parameters in the transaction chain are ordered.
* Addressed some minor items from RP review feedback.
* Refactoring following rebase from master.
* Address RP PR review comments (round 2)

This includes all of the cash selection logic, JSON support using jackson and a bunch of utilities which are not relevant to contract verification. The exception to this are Interpolator which has been moved to the IRS demo, and PhysicalLocationStructures.kt which is now in explorer.
* Allow for duplicate (contract class, version) signed attachments in devMode.
* Code clean-up.
* Fix compilation error in test code.
* Additional gating/warning and added Unit test for development mode behaviour.
* Remove locks around database access in AppendOnlyPersistentMap and introduce
a unit test that checks that known deadlock scenarios of the old version
are avoided.
* Fix Deadlock unit test
* Add some extra latching to try and make timing less fragile. Can never be perfect though.
* Review feedback, and some thread safety fixes.
* Start pooling classpath scanning
Quickly patch synchronisation of attachment class loader cache. Needs a revisit but more complicated due to DJVM.
Annotate away for DJVM
Take ClassGraph utils into their own file so we can exclude for DJVM
Clean up a little
* Daemonize the threads
* Seems to be some concurrency problems with use of ClassGraph. Using a mutex for now to work around.
Merged three tests into one to avoid repeating the same node startups. The assertions the original tests made can be done in one test without any contamination.
* Removed `restart node successfully with suspended flow` as it duplicates `TraderDemoTest#Test restart node during flow works properly`
* Removed the need for a notary
This is only testing the internal cordappForClasses method which is used for internal testing. This method is covered by other unit and integration tests.
CORDA-2497 fix
* Added test to show the fix working.
* Now backwards compatible.
* Refactored out some duped code.
* Added better explanations for what's going on.
* Fixed test which was failing due to the serializationEnvRule problem.
* Addressed Tudor's review comments.
The column 'uploader' was marked as not updatable entity so any update wasn't propagated to the database when the attachment was uploaded again and the uploader field was changed to a trusted one. Also 'saveOrUpdate' removed, the entity is already managed, saveOrUpdate is for detached/new entity.
Upgrade from node 3.0 to 4.0 fails to create versions of whitelisted JARs from networkParameters - read parameters from file at first as in Corda 3.0 there no relevant table, then try from the table.
As this is migration, the code will run only once on each node, she increased log level to info for messages. Tested using https://r3-cev.atlassian.net/browse/R3T-1549

* Rewrite of upgrade notes for vault state query updates
* Address review comments
There were two issues:
* The original "sealing violation: can't seal package net.corda.nodeapi" issue was due to the isolated CorDapp containing some code in the net.corda.nodeapi namespace. This has been moved to the isolated namespace.
* The test was not correctly creating the second transaction with the dummy command
* Add whitelists and custom serializers from cordapps to serialization context
* Remove changes in TransactionBuilder, add caching

The version of contract attachments that are whitelisted should be read from NetworkParameters.whitelistedContractImplementations.
It use the lattes network map from db with the highest epoch.
* Fixed bug in state pointer search and added tests.
* Blacklisted problematic package.
* Addressed Shams' comments.
* Addressed round two of comments.
* Fixed another bug whereby the DFS gets stuck in an infinite loop.
The API has been reverted to be completely ABI compatible with V3, and the small changes that were made to the wire format in https://github.com/corda/corda/pull/4260 have also been reverted.
Corda Node ensures a given contract class and version can be sourced from only one signed and trusted Attachment (JAR).
An attempt to import a signed JAR as a trusted uploader (or promote to be trusted) with a class and version already present in the other trusted Attachment will raise DuplicateContractClassException.
Minor fixes to Hibernate Attachment Query parser (original query to select attachment without signers would always return no attachments)
Move Raft and BFT-Smart notaries back into node to preserve backwards compatibility.
* Allow overriding full node config when using internal mock network parameters.
* Make BFT-Smart notary start up in prod mode as well
* Move raft & bftsmart notaries to net.corda.notary.experimental package
* Make sure Raft notary handles reference state edge cases correctly.
* Make sure BFT-Smart notary handles reference state edge cases correctly.
* Include notary schemas in node internal schemas
* Undo Raft notary table schema changes to maintain compatibility.
* Add cordapp code signing dev key to production blacklist.
* Remove code used to generate the actual PK hash (it is now attached to the JIRA story)
* Remove wiki page reference.
* Remove the non redundant cash transfer.
* ENT-2923 - remove db access code from the verification thread pool
* Remove worker pool for tx verification and disable db access.
* Address code review comments
* Reduce the operation of ip autodetect to nodes specifying localhost, rather than any node with a 192.168.x.x or 10.x.x.x address. Also, catch the common user error of specifying 0.0.0.0 in p2pAddress.
* Fix test that uses invalid config
Apps may depend on the previous behaviour of catching Throwable rather than just Exception. Better to not risk this break and instead provide a helper to throw Errors.
Also using Consumer to avoid ugly usage in Java for doOnSuccess and doOnFailure.
* Update the documentation for trackBy to better indicate that updates are not filtered according to the query criteria
* Add a test that shows the behaviour, which is skipped for now until a solution is implemented.
* [CORDA-2376]: Unable to make contract attachment trusted if it was received via network (fixed).
* [CORDA-2376]: Wrote some tests.
* [CORDA-2376]: Wrote some tests.
* [CORDA-2376]: Code review changes.
* [CORDA-2376]: Code review changes.
* Fixed incorrect attachment loading integration test
`AttachmentLoadingTests.test that attachments retrieved over the network are not used for code` was a false-positive - it was incorrect on multiple levels. Fixing it required updating the finance:isolated CorDapp, at which point it was given the new MANIFEST metadata for V4, and moved out of the net.corda.finance namespace to avoid package sealing issues.
The new test exposed a bug in the LedgerTransaction verification logic. This was cleaned up as it was too easy to verify on the wrong instance.
The overload that takes in a String does NOT check that the exception thrown has that message, which is what these tests are assuming. Rather it's the assertion message when the test fails.
* CORDA-1839 - Remove race condition between trackBy and notifyAll
* Fix null check

* api-current.txt change to remove warnings of abstract methods in new interfaces.
* Fix indent
TestCordapp has now two implementations to clearly separate the two use cases it has in the Corda repo:
* TestCordappImpl which implements the revised public API of TestCordapp; namely that a TestCordapp instance references a real CorDapp jar on the classpath. This is either an external dependency jar in which case it’s taken as is and given to the node, or it’s a local gradle project in which case it’s compiled using the gradle “jar” task to generate the CorDapp jar. This approach means the jar has all the original CorDapp versioning information, which is important that it’s correct when testing. To this end, TestCordapp only needs to expose the ability to specify the app’s config. All the remaining properties have moved to CustomCordapp.
* CustomCordapp for creating arbitrary custom CorDapps, including specifying the jar’s MANIFEST values. This is internal API and only used for testing the platform. Technically this shouldn’t implement TestCordapp but does so to reduce the complexity of the driver and mock network.
* Split Workflow and contracts of Finance App into separate Cordapps, part 1 - content which is different between OS and ENT is still in contract Cordapp.
* Move CashSelection implementations to workflow module.
* Move CashSelection implmentations to workflow module.
* Move finance module to finance-flows, top level finance module is empty.
* Move finance module to finance-flows, top level finance module is empty.

* Align CorDapp configuration filename with workflows jar.
* Fix breaks caused by finance module naming changes.
* Final alignment between OS/ENT of finance contract code.
* Make TimedFlows retry forever, and cap the growth of the time out interval.
* Only time flows for restart if that is sensible (i.e. notary flows that actually have an alternative node to talk to).
* Move check for multi node notary into getter so it the `canBeRestarted` attribute can't be set too late.
* Make restartable timed flow a concept on SubFlow metadata and the relevant events so we can handle it properly for subflows based on their metadata.
* Addressing review comments.
* Consistent naming
