* Construct standard flows using PartyAndCertificate, and add support for launching
flows that are constructed with PartyAndCertificate or just Party.
* Store PartyAndCertificate in network map service
* Expand identity service to store certificates along with all identities.
This removes the need to do manual registration using the PluginServiceHub. As a result CordaPluginRegistry.servicePlugins is no longer needed. For oracles and services there is a CorDappService annotation.
I've also fixed the InitiatingFlow annotation such that client flows can be customised (sub-typed) without it breaking the flow sessions.
Replace X509Certificate with X509CertificateHolder for consistency in implementation of how X.509 certificates
are managed. Using the Java standard class entails the actual implementing class being one of several options
depending how a certificate is built, which makes serialization/deserialization with Kryo inconsistent as some
of these forms cannot be directly built from outside restricted classes.
* De-anonymise parties in AbstractStateReplacementFlow flows
* Convert transaction key negotiation to a subflow instead of utility functions
* Add serialization support for CertPath
* Restructure cash flows so that a counterparty flow can be added later
* Rename raft-notary-demo project to notary-demo
* Refactor serialisation filtering to allow BFT SMaRt to work, it no longer relies on the jdk.serialFilter system property
* In NodeBasedTest remove whitespace in node directory names for consistency with cordform and driver
Remove mock identity service and merge it with the in memory identity service. The two services
provide extremely similar functionality, and having two different version for production/test
risks subtle implementation differences. On that note, this patch includes changes to a number
of tests which worked only with mock identity service.

* Raft notary demo now defined in one place that both IntelliJ/driver and gradle/runnodes can run
* New module cordform-common for code common to cordformation and corda
* Add single notary demo
Switch to using AbstractParty as the standard identifier for parties in
states, so that full parties can be used during construction of
transactions and anonymised parties when the transaction is being added
to the ledger.
* Fix: Add missing @StartableByRPC to fix the Raft notary demo
* Make loadConfig take a Config object, for cordformation Node
* Unduplicate User.toMap
* Unduplicate WHITESPACE regex, choose possessive form
* Use slash to make a Path
* Remove Companion where redundant
* Remove unused code
* If the p2pAddress provided by the configuration is not public, the node tries to discover the public IP:
- First by checking the network interfaces
- If not found, sends a request to the network map service
* Enable initial connection retry
* Improve error handling
* Update docs
Specifically, make the IDE/driver and gradle/NodeRunner methods of launching the demo behave more similarly, with a view to configuring them the same way.
* Add option to driver to nominate a node as network map, so that the driver-based demo doesn't run an additional node
* Change gradle ports to match those chosen by driver
Add functionality for generating certificate paths from identity
certificates to transaction certificates, validating, storing and
retrieving those certificate paths.
Move AbstractParty, AnonymousParty and Party into a new net.corda.core.identity package,
as they're not really cryptography tools, and in preparation for further code coming in
for identity.
Optimize imports on many files to clean up the resulting refactor.
Mark several functions in X509Utilities as @JvmStatic so they're readily accessible from Java.
Add functions for modifying common name of an X.500 name, either direct replacement or adding a postfix.
This removes the need for the shareParentSessions parameter of FlowLogic.subFlow. It also has the flow's version number so FlowVersion is now no longer needed.
Change the legal name of parties to be an X500 name. This ensures that we aren't converting between
common names and X500 names in various places, eliminating substantial scope for error in the conversion
process. As a result, all node names must now be full X500 names, which has impact on most configurations.
* Added queryBy(QueryCriteria) Vault API and Junit tests.
* Minor fix following rebase.
* Spit out Vault Query tests into separate source file.
* WIP
* Enable composition of QueryCriteria specifications.
Additional JUnit test cases to validate API.
* Added Deprecating annotations.
Added QueryCriteria for set of contractStateTypes
* Minor tweaks and additional JUnit test cases (chain of linear id)

* Fixed typo.
* Clarified future work to enforce DB level permissioning.
* Moved PageSpec and Order from QueryCriteria to become parameters of Query itself.

* Exposed new Vault Query API functions via RPC.
* Fixed compiler error in java test.
* Addressed a couple of minor PR review scomments from MH.
* Major updates following PR discussion and recommendations.
* All pagination and sorting arguments are optional (and constructed with sensible defaults).
Added Java helper functions for queryBy and trackBy interfaces.
Added Java trackBy unit tests.
Miscellaneous cleanup.
* Added Generic Index schema mapping and query support.
* Query criteria referencing Party now references a String (until Identity framework built out).
Added participants attribute to general query criteria.
* Fleshed our IndexCriteria including PR recommendation to define column aliases for index mappings.
* Removed all directly exposed API dependencies on requery.
* Updated documentation.
* Provide sensible defaults for all Query arguments.
Add RPC Java helpers and increase range of Vault Service helpers.
* Further improvements (upgrading notes) and updates to documentation.
* RST documentation updates.
* Updates to address RP latest set of review comments.
* Updates to address MH latest set of review comments.
* Updated to highlight use of VaultIndexQueryCriteria to directly reference a JPA-annotated entity (versus the indirect, explicitly mapped attribute to GenericIndexSchema approach)
* Aesthetic updates requested by MH
* Reverted Indexing approach: removed all references to VaultIndexedQueryCriteria and GenericVaultIndexSchemaV1 scheme.
* Final clean-up and minor updates prior to merge.
* Fixed compiler warnings (except deprecation warnings)
* Reverted all changes to Vault Schemas (except simple illustrative VaultLinearState used in VaultQueryTests)
* Reverted all changes to Vault Schemas (except simple illustrative VaultLinearState used in VaultQueryTests)
* Commented out @Deprecated annotations (as a hedge against us releasing M12 with the work half-done)
* Renamed RPC JavaHelper functions as RPCDispatcher does not allow more than one method with same name.
This is an intermediary step to introducing X500Names in all Party instances, which adds:
* Party constructor which accepts X500Name and then converts it to string.
* startNode() function which takes in X500Name instead of String
* Numerous legal name fixes to use full distinguished names
Core flows, which are baked into the platform, are also versioned using the platform version of the node. Several core flows, such as the data vending ones, which were provided via plugins are now instead baked into the node.
BFTNotaryServiceTests generates a master node independently of the cluster nodes, so it can put it
at the end of the list of nodes. The calling function however treats the first node in the list as
the master, not the last node. This simplifies the code while maintaining the same behaviour.
* Add information on why state machine was removed from StateMachineManager.
There are two cases: normal end of flow or error.
Return flow result as part of state machine remove data.
Make Change a sealed class with Add and Remove.
fiber.actionOnEnd takes ErrorOr<R> parameter.
* Remove unnecessary fields from StateMachineManager.Change.
* Add information on who started flow on a node with name where possible.
Add sealed class holding information on different ways of starting a flow: RPC, peer, shell, scheduled.
* Remove invokeFlowAsync from ServiceHub, move it to ServiceHubInternal.
We shouldn't be able to start new state machines from inside flows.
Move functions for generating transactions into OnLedgerAsset from various locations in
the code (VaultService, AbstractConserveAmount, etc.) to unify the code paths and reduce
duplication.
* Remove progress Observable from FlowHandle, unless explicitly requested.
* Refactor FlowHandle creation into FlowStateMachine.
* Prevent server-side queue subscription for dummy Observable.
* Refactor so that RPC client does not receive any unused progress Observables. This is the simplest way of ensuring we have no dangling "hot" Observables when the RPC client closes.
* Test flow has correct handle.
* Resolve some compiler warnings.
* Document how starting a flow does not involve progress tracking by default.
* Update changelog and release notes for RPC API.
* Rename new RPC API to startTrackedFlow().
* Remove optimisation because of its affect on the client-side.
* Update documentation.
This introduces new functions for fetching parties by their X.500 name, Kryo serialization support for X500Name objects, an X500Name generator and some X509 utility support in preparation for full X.500 name support.
Add CompositeSignature and CompositeSignatureWithKeys classes as part of preliminary work to make CompositeKey signature validation compatible with java.security classes, so that these keys and signatures can be used readily in X.509 certificates.
Standaridise the identity names of Alice, Bob and Charlie, notary, map service, etc. in order
to ensure consistency across the code base and reduce number of places that have to be changed
to introduce proper X.500 names.
Move Alice, Bob & Charlie identities into the utilities package so they can be used in demos
* Make CompositeKey implement PublicKey
The initial implementation of composite keys as their own distinct class separate from PublicKey
means that the keys cannot be used on standard classes such as Certificate. This work is a beginning
to modifying CompositeKey to being a PublicKey implementation, although significant further work
is required to integrate this properly with the standard Java APIs, especially around verifying
signatures using the new key type.
* First stage of making CompositeKey implement PublicKey interface. Revert to using PublicKey everywhere we expect a key.
* Move algorithm and format into companion object (#432)
Move algorithm and format into companion object so that they can be referenced from other
classes (i.e. the upcoming signature class).
* Add simple invariants to construction of CompositeKey.
Builder emits CompositeKeys in simplified normalised form. Forbid keys with single child node, force ordering on children and forbid duplicates on the same level. It's not full semantical normalisation.
* Make constructor of CompositeKey private, move NodeWeight inside the class.
Add utility function for Kryo deserialization to read list with length constraints.
Add tests for CashIssueFlow, CashPaymentFlow and CashExitFlow. While these were mostly covered by other tests
already, CashExistFlow was not, and any bugs would be harder to identify because they are mixed in with other
functionality (i.e. vault tests)
* Fixed bug whereby Cash Exit was not taking into account the issuer reference.
Added additional JUnit tests for coin selection by issuer.
Added some trace logging in AbstractConserveAmount.
* PR review: added additional state with 3rd issuer reference in test.
Clarify exceptions thrown from loading a key store as a general cleanup. Also tightens the
exceptions caught when loading key stores from AbstractNode, so in case of an unexpected error
we don't silently drop the exception.
This eliminates JIT java compilation and the consequent need for
tools.jar (which doesn't get shipped in DemoBench). It also makes
development more pleasant by avoiding weird IDE integration issues
that came from having java-in-resources.
* Reduce warning and info messages in node log files (Artemis)
Add an additional lof message for conflicting states identified by the Notary.
* Upgraded severity of user login message from trace to debug.
* Suppress Artemis log4j WARNING's for core.server.checkDeadLetterAddressAndExpiryAddress
* Test SELECT WHERE IN composite key using requery 1.2.0
Upgraded Vault Service code to use Requery 1.2.0 SELECT .. WHERE IN
Updated generated schema code with Requery 1.2.0
Upgrade to Requery 1.2.1
Upgrade to Requery 1.2.1 - converted to use update DSL with composite key
Removed redundant JDBC SQL test cases.
Minor updates following PR review comments from RP.
* Streamline companion object initialisation.
* Display Corda node legal name in JVisualVM Console for MockNode testing.
* Removed dash in displayed corda node name.
* Reinstated the dash in displayed corda node name (as JVisualVM does not parse the space correctly)

Fix CommercialPaper test (was missing auto-generation of CONTRACT_CASH table)
Revert default JVM size back to 200Mb.
Revert default number of iterations in Explorer Node Simulation mode (back to 10000 with .5 sec sleep interval).

Fixed small memory leak.
Removed stray } in logger trace message.
Slight rewording of description of Soft Locking in docs.

generateSpend is now Suspendable (calls sleep method on flow upon coin selection retry).
Added companion function to enable a Strand to sleep but without locking transactional context.
Improved logging, changed to StateNotAvailableException, using Flow sleep upon retry, tweaked SELECT criteria in coin selection, fixed bug when insufficient states selectable, generateSpend is now @suspendable
Improved handling and logging of flow results in Simulation Mode.
Fixed minor error in sleep when not an active flow.
Retry coin selection when unavailable states (as these may become available as new states).

Improved trace logging for coin selection (SQL row level info).
Correctly calling FlowStateMachineImpl sleep (now inlined and working correctly)
Fixed rebase error.
Remove redundant TODO message.
RBS report problems with multiple nodes being able to find each other in the identity service. This extends the name
lookup test case to try three nodes, to check all of the stored values, and to use random keys rather than static.
Add trace log of identity registrations to aid with tracking state.
- :finance and :node-schemas no longer contain junit-quickcheck-*
and so no longer need to exclude javassist:javassist.
- RPCStructures.kt has been moved to :node-api, and so we no longer
need the commons-fileupload dependency here.
The shell is embedded in the node and offers the ability to monitor
and control the node via the launching terminal.
Still to do:
* Switch to a fork of CRaSH that we can maintain ourselves, and merge in Marek's SSH patch so we can enable SSH access.
* Add persistent command history that survives restarts.
* Tab completion for the 'flow' and 'run' commands.
* Remove the 'jul' command and replace it with a command that lets you see and tail the log4j logs instead.
* Fix or remove the other crash commands that have bitrotted since 2015.
* Record a metric for the duration and rate of execution for every flow. This is useful for task intense scenarios to detect performance degradation.
* Measure both successful and failed flow durations

* CORDA-304: Migrate DriverBasedTest from node into test-utils.
* CORDA-304: Rename .fx. package to .jfx. to prevent confusion with "exchange rate".
* CORDA-304: Rename module to ':client:jfx'.
* We were leaving trailing attachmentStorage on pooled kryo instances after some tests. Changed attachment storage logic to make it impossible to leave it behind.
* Some low level tests corrupt the Kryo config, so do not return to pool when this is the case. Also, we discovered that Kryo is caching class name to class resolution. We don't want to do this where attachments are involved. The errors raised highlighted a class missing from the whitelist. Need to write a unit test to test the class loader issue.
* Unit test for attachment class loading with kryo.
* Non-ssl artemis acceptor for RPC connection. (#271)
* New non-ssl acceptor in artemis server for RPC connection.
* Rename artemisAddress with messagingAddress
Rename artemisAddress with messagingAddress so that the node configuration file properties match
the code variable names.
Rename artemisPort to messagingPort in Gradle configuration to match node configuration naming.
* Add rpcPort configuration option for Gradle
* Update docs to reflect changes to RPC port configuration
* Renumber ports in example CorDapp to match numbering used elsewhere
* Restructure upgrade guide
* added config file checks on corda startup to make the upgrade path a bit smoother.
Add Capsule configuration for the webserver JAR, so that the classes-only `webserver.jar` is published as well
as the full fat `corda-webserver.jar`. This is required for running the tutorial/template from IntelliJ.
Convert NodeVaultService states to return Iterable (backed by Sequence) Vs the old way using a List. Worth noting this relieves memory pressure as the number of vault states grows.
* remove toList in ContractUpgradeFlowTest
Basic crypto API to support 5 signature schemes and MetaData-ed signatures.
Supported schemes: (1) RSA_SHA256, (2) ECDSA_SECP256K1_SHA256, (3) ECDSA_SECP256R1_SHA256, (4) EDDSA_ED25519_SHA512, (5) SPHINCS-256_SHA512.
To sign a transaction, a signer should create a MetaData wrapper that contains transaction's merkle root and some extra information, such as signer's public key, timestamp and visibleInputs. Actually, MetaData is utilised to support a practical partial, blind and extra-data attached signature model.
When a MetaData object is signed, the signer sends a TransactionSignature object that contains the signed output and the corresponding MetaData object.
Remarks:
This is an temporary solution for signature algorithmic agility. Further development is required for a robust and extensible Crypto Manager/Provider PKI that will support certificate creation, key generation, signing/verifying, deterministic key derivation, encoding formats, SGX/HSM support, identity and key management, versioning, revocation, asynchronicity, metadata, partial sig. policies etc.
* QueuedObservable could not leak due to hard references. Have made it weak referenced but also had to reference count a hard reference to prevent early GC. Explained in comments.
* Improved comments.
* Fixed typo
* Fixed another typo
* CORDA-265: Implement "ALL" permission for RPC users. Users with this permission in node.conf can use any flow.
* CORDA-265: Ensure that we always close the RPC proxy object after each test.
* CORDA-265: Refactor construction of dummy RPC client into an abstract base class.
* CORDA-265: Document RPC "ALL" permission.
* BFT notary prototype: add a non-validating service.
Each replica now validates the transaction timestamp and returns an individual signature to the BFT client. The client then returns a list of signatures back to the notary service flow.
The validating variant is still incomplete - it requires the ability to suspend flows on arbitrary function calls.
* Exclude old version of Javassist in favour of Hibernate's version.
* Comment why we are excluding javassist:javassist, and add TODO for when junit-quickcheck 0.8 is released.
Make notary flow return a collection of signatures to support the BFT notary. For a single-node or RAFT notary it would just contain a single signature.
* Make the network registration process more verbose
* removed gradle task for building standalone jar for the certificate signing request utility
* Added a flag "--initial-registration" to the corda jar to start the registration
* Initial prototyping with Requery as a persistence replacement for Exposed/Hibernate
Applied changes following PR review by RP
Updated timestamp naming (removed committedTimestamp) and StateStatus (removed AWAITING_CONSENSUS) after discussion with RP.
Removed FungibleState and LinearState schemas (and associated tests) - awaiting Requery uni-directional relationship fix.
Added Transaction propagation such that requery re-uses any existing transaction context.
Made requery default logging configurable (disabled by default)
Nullable fields are now truly nullable (in the Kotlin and DDL sense)
Fix for SimmValuation integration test.
Workarounds applied to resolve Requery issues when sharing Transactional context.

* Add webAddress back to NMS as it shifts the port allocation for all subsequent nodes and causes all demos to break.
* Attachment demo: fix node names
* Notary demo: fix certificate paths & ports
* IRS demo: role decider fixed to allocate roles properly. Previously it used to pick current node as the Fixer, causing both nodes to initiate the trade flow, resulting in double spend exceptions..
Make FinalityFlow do more, and be used more consistently.
Add a new waitForLedgerCommit API that is intended to be used at the end of flows, or at any other point where a flow wants to wait for a transaction to finalise (but the finalisation flow is being done by someone else).
Update the docs a bit.
* Prevent node from starting across upgrades (until we support it better).
On first run a version file is created in the node dir, and on subsequent runs the node version is matched against it.
* Move version check from caplet to node.
InMemoryNetworkMapCacheTest was not actually asserting that an expected exception was thrown, which
meant when earlier changes to the service changed the operation it wasn't caught. The service now
overwrites previous node if a new matching node is added, and this updates the test to follow that
design.
Change Party instances to be uniquely identified by the owning key, without taking into account name.
This requires that mock node key generation is reworked so that keys for services and the node itself
are distinct, otherwise the network map service cannot differentiate them.

Remove TransferRecipient from StateMachineManagerTests to get rid one of the approximately 6 different ways
in which we refer to endpoints, as part of work to simplify this data model.

* Add logging to avoid node startup "hang" when it attempt to connects to the network map, also can use as a hint telling user Network map might be down or unreachable.
This reveals that building the first RPC client is ludicrously slow (like 1.8 seconds) but subsequent builds are more like 30 msec. This might be interpreter overhead, or it might be due to Artemis/SSL doing lots of piggy lazy initialisation or something. But at any rate it may be worth investigating a bit later.
* Update notary change flow to support encumbrances.
Move encumbrance pointer from ContractState to TransactionState.
* Refactor & add new encumbrance tests
Check that the SMM.add method is being called on the SMM thread and throw if not. Make ServiceHubInternal.startFlow() do a blocking call onto the server thread. Update unit tests.
This resolves an issue whereby the scheduler was starting flows outside of the server thread, which isn't intended.

Remove old refs to Royal Mint and Federal Reserve
Increase JDBCHashMap default bucket size. With the current implementation of the Vault, once the number of stored transactions (or UTXO) goes over the max bucket size we end up reloading each transaction from the db and deserializing it, which causes severe performance degradation.
Add unit tests of ScheduledFlow running on simulated network.
Just use existing DumyContract in test
DummyContract requires value equality so that assertEquals over states works as expected.
Remove blank line.
Add TODO on waitQuiescent.

which isn't awesome either but at least tells the user what to do.
Fix handling of node shutdown so protocols don't blow up when they encounter the messaging layer already shutdown. Protocols will also stop resuming once shutdown has commenced.
No longer delete all pending messages from the database and move into memory before putting back into the database again, which is vulnerable to failure. Now we delete individual pending messages on successful redelivery.
Speed up JDBCHashMapTestSuite by 3min on my laptop by avoiding Exposed table existence checks each time a map/table is created by re-using the map/sets across tests (after clear()-ing to reset their state).
InMemoryNetworkMapCache.getNodeByPublicKey() previously returned null if multiple nodes matched
a given public key (for example if the same node is registered more than once with different

Delete duplicated code
some minor changes, including gitignore rule changes. The largest change
is replacing the current fresh key for each transaction with a single
static identity in preparation for aimproved and more fleshed out key
sharing infrastructure.
Use synchronized wrapper over set.
Drop discard message to trace level logging.
Fix code layout
Use lazy trace extension method
Track message id's to deduplicate replays. Widen the auto-acknowledgement window of Artemis back to the default.
Use synchronized wrapper over set.
Include tx message unique id in checkpointed data.
Add test for checkpointed resend
Fix bug in not getting UUID off message.
Tidy formatting
Add explanation comments to test asserts
Put unique id even on Client messages.
Tidy formatting
Add some unit tests of the late init behaviour.
Fix merge error
Change statemachine logic to use an in-memory only flag on checkpoints to track their materialisation during startup.
Add annotations for test method
Fix possible race condition on storing checkpoint objects
Correctly create checkpoint
Use then helper function
Cleanup imports
The RPC mechanism uses message queues and is essentially conventional except for the fact that it supports marshalling observables. An observable encapsulates a stream of ongoing events, and server-side observables sent to the client are automatically bound to message queues and managed by Artemis.
Add log4j-web to node so it stops complaining that it's running in a web environment without that option.
Longer term we may want to split the web parts into their own optional extra for node, but for now I think
this is a sensible solution.
This moves a lot of the test support code into its own package which is only imported for tests,
so it's not shipped as a part of core Corda. The node currently depends on this support code to
compile, although future work could try to separate this out. This change highlights that parts
of production code is dependent on test elements (i.e. dummy keys), and makes it harder for
such accidental crosses to occur later.
An integration test category is also added as part of this work, to contribute towards COR-345.
Add new protocol which manages the entire process of taking a signed transaction ready
for notarisation, through notarisation and onto recording it both locally and informing
remote nodes.
This protocol also optionally can include the ClientToServiceCommand which triggered a transaction
being created, to give the remote nodes context on why a change occurred (i.e. "You are being sent
£100")
Fixup after rebase and fix issue with checking previous deployment of bridges
Correct comments on ArtemisMessagingClient constructor
Fixup rates fix demo
Get rid of when statements
Make NetworkMapCache send modify as well as add//remove events. Make inboxes for nodes persistent.
Suppress warnings
Fix message acknowledgement so that it actually consumes messages properly.
Change queueName to SimpleString to stop lots of wasted conversions
Get rid of spurious import
Tidy up and add comments
Update to include comments on PR
Remove unnecessary import
Remove the ability to exit cash not held by the cash issuer; this solves a number of problems:
* Ensuring owner of the cash is aware of the funds being destroyed
* Determining where to send any change resulting from partial exiting of funds
* Auditing the destruction of funds
Try providing a helper interface to encourage enforcing LinearState rules
Fixup after rebase
Change to using Clauses for verifying LinearState standard properties
Fix whitespace change
Tidy up ClauseVerifier after PR comments
Change from SecureHash to a TradeIdentifier class
Change TradeIdentifier to UniqueIdentifier
Add observable for transactions being stored, so the UI can show transactions as they're received, rather than being
limited to the summarised version available from the wallet service.
- Fix thread safety issues in ArtemisMessagingClient. The Artemis API isn't thread safe, but that isn't well documented and it will happily invoke callbacks in parallel.
- Add discussion of how we tackle threading currently in the codebase and make a few other improvements.
- Add a shutdown hook so we stop properly when the user presses ctrl-c
First working Exposed-assisted persistent wallet
Cleaned up Exposed-based persistent wallet
Cleaned up warnings
Fixed up some generic types
Improved comments
Fix up TODO comment
Hikari and config integration
Fix existing tests
Clean up after looking at PR
Clean up commented out lines
Fix initialisation of IRS demo leaving database open
Fix up after rebase
Review feedback. Main change is lazy wallet iteration.
Rebased and incorporated config changes.
Use standardised config loading. Make wallet cash test use persistent wallet.
Added test to ensure wallet retains state in database across instance creation.
Tidy up whitespace and fix bug in test.
Changes include:
- LedgerTransaction is now much more central: it represents a fully resolved and looked-up tx, with the inputs available.
- TransactionGroup and TransactionForVerification are gone. There is a temporary TransactionForContract class for backwards
compatibility but it will also be gone soon.
- ResolveTransactionsProtocol is simplified, and now commits a tx to the database as soon as it's determined to be valid.
- ServiceHub is now passed in more consistently to verification code, so we can use more services in future more easily e.g. a sandboxing service.
- A variety of APIs have been tweaked or documented better.
This change reduces the testing confusion that can occur when cash is issued by one of the parties in a transaction rather than e.g. a neutral third party like a central bank.
Break down what is referred to as "topic" of a message into its component parts. This splits the
general topic from the session ID, so it's clear where a session ID is provided, and whether any
given topic string includes a session ID or not.
Move FiberRequest out to a top level class, both because it is expanding as functionality is added,
and to enable alternative state machine implementations to share it.
Where state machine change events are to be serialized for relay to external systems, serializing the entire
protocol is excessive. Instead being able to identify changes based on the ID of the fiber is a lot simpler
for these use-cases.
Unhandled messages in the in memory messaging network can disrupt runNetwork(), as they
result in getNextQueue() returning null, irrespective of whether there is further work
which could be done. This modifies the flow to loop through the remaining transfers on
the queue before giving up, rather than stopping after the first.
- Move code out of ambiguously named TestUtils files (there were three). Sometimes it's simpler to just put these things into the contract source files directly.
- Remove JavaTestHelpers objects (there were three), in favour of just giving the top level kotlin file class better names.
- Misc other small tweaks and cleanups.
As the timestamping authority is now always the notary service, contracts should
no longer be using name-based lookup of the timestamping authority (as this will
generally be wrong). This introduces a new "timestamp" property on a transaction,
and updates most contracts to refer to it.
In some cases (IRS, CommercialPaper) there are transactions with no input states
to derive notary from, that use timestamps. In these cases a notary is specified
in the command.
- Rename NodeWalletService to InMemoryWalletService and move into the core module where it's available for unit testing.
- Make a new NodeWalletService that just inherits from InMemoryWalletService and doesn't customise it at all, for now.
- Take the cash specific functionality out of Wallet and into an extension property in the Cash contract (this compiles as CashKt.getCashBalance(wallet) for java users).
- Return the generated states in the fillWalletWithTestCash function.
Add issuer of a cash when referring to amounts of cash (except for the very few cases where
the issuer is not important, such as when referring to aggregated totals across a set of
issuers). Replaces CommonCashState with TokenDefinition, as a more accurate reflection of
what the class represents.
Split the verification and commands for the Cash contract into a new AbstractCashLike
class, and make Cash a concrete implementation of that class, specialised for dealing
with Currency as the underlying token.
Make the Amount class generic so it doesn't have to represent a quantity of a
currency, but can handle other things such as assets as well, or extended detail
(for example a currency-issuer tuple).
