* Improved support for testing custom schemas using a MockNetwork.
* Removed `requiredSchemas` from CordaPluginREgistry configuration
Custom schema registration now uses classpath scanning (CorDapps) and explicit registration (tests) following same mechanisms as flow registration.
* Updated following PR review feedback.
* Helper function to return Kotlin object instance fixed and moved to core InternalUtils class.
* Fixed auto-scanning Unit test to assert correct registration of custom schema.
* cleanup comment.
* Changes following rebase from master.
If the serializer is going to support enumerated types then the class
carpenter also has to
Refactor the Carpenter schema and fields to add an enum type, add code
in the carpenter to generate enum's and of course add tests
* ContractState's contract type has been moved to TransactionState and is now a string representing the class name of the contract class to allow classloading of arbitrary contracts from custom classloaders.
* Upgraded isolated JAR to new version.

* [CORDA-303]: Updated change log and added Javadocs.
* [CORDA-303]: Cleaned up test.
* [CORDA-303]: Removed blank lines after class or function declarations.

* All Contract Upgrade functionality performed within a corresponding flow.
Removed RPC API calls for contract upgrade authorisation / de-authorisation.
Added persistence using AppendOnlyPersistentMap.
* Changed to using a PersistentMap to ensure entries can be removed (was causing failing de-authorisation tests).
Fixed all warnings.
* Added mandatory @Suspendable annotations to flows.
* Do not instantiate object unless overridden.
* Updated changelog and CordaDocs.
* Persistence simplification: only store upgrade contract class name (not serialized object)
* Remove nullability from contract_class_name DB column.
The example code uses cash flows and contracts, but doesn't depend on the finance CorDapp. This happens to work at the moment but should be corrected anyway.
Work on database backed NetworkMapCache
Make NodeInfo JPA entity.
Enable node startup with it's database network map cache. Fix schema.
Make node not wait for finishing network map service registration if it
successfully loaded data from database.
Add tests for startup without NetworkMapService.
* Rename networkMapRegistrationFuture
Change networkMapRegistrationFuture to nodeReadyFuture, it no longer
indicates the NetworkMapService registration, because we are able to run
network without map service configured.
* Partially integrate database into NetworkMapCache
Full integrtion will come with service removal.
Move MockServiceHubInternal to net.corda.node.testing
* Add workaround to transaction scope race
Temporary workaround to force isolated transaction (otherwise it causes race conditions when processing
network map registration on network map node).

Infer the node's location based on X500 name
Add serial number on NodeInfo
For tests of running without NetworkMap, start nodes with nonexistent NetworkMap address

Move parseCurrency back onto Amount companion.
Fix smoke tests
Fixup after merge.
* Add LegalProseReference annotation
* Migrate code from autogenerated javascript to TypeScript source
* Add instructions to rebuild the web resources
* Make installWeb more reproducible
This improves the Java API and makes it more idiomatic. The methods
were not moved to be static methods of the relevant types in all cases
due to a bad interaction with a Kotlin auto-completion bug, and because
static methods on interfaces are new in Java 8 and Kotlin is not yet
emitting Java 8 bytecode.
Also, introduce a packages.md file so packages can be documented.
* Removed notary_key (and all references) from vault schema.
Fixed incorrect NOTARY usage in certain tests (cash consumption)
* Fixed broken test.
* Replace CommonSchemaV1.Party in all VaultSchema tables (and associated queries) with string'ified X500Name's only.

Cleaned up several compiler warnings.
Change CashIssueFlow to always issue to ourselves, and require the cash is then moved in a separate payment
operation. This more closely models actual operation inside banks, and is a step towards making all move-like
operations go through a uniform verification process.
* Remove IssuerFlow as it is dangerous and its presence in the finance module risks accidental use in non-test code. As written it will issue arbitary amounts of currency on request from any node on the network, with no validation barring that the currency type is valid.
* Unify interface to CashIssueFlow to match the previous IssuerFlow
*Remove dummy public keys in preference for EdDSA keys generated from fixed entropy sources, as a more accurate reflection of real uses. Also eliminates a serialization format issue with dummy keys which would have to be resolved otherwise.
* Remove deprecated 'by' keyword from contracts DSL
* Remove deprecated parts of CordaPluginRegistry
* Merge identity registration of well known and confidential identities
* Move verification logic into PartyAndCertificate from IdentityService
* Add note about why PartyAndCertificate exists
checkSignaturesAreValid() calls TransactionSignature.verify(), which throws InvalidKeyException but
checkSignaturesAreValid() did not indicate it could throw InvalidKeyException.
* Remove hard coded commercial paper issuer from trader demo
* Issue commercial paper from the Bank of Corda node, as per previous hard-coded issuer name
* Issue cash from the Bank of Corda node rather than in response to the buyer node requesting issuance

Matching can be done with case insensitive substrings in the identity service, RPC and shell. In future cleverer matching should be possible, e.g. using Lucene or RDBMS free text search features.
Fixed issue where Corda services installed in unit tests were not being marked as serialise as singleton. Also the driver now automatically picks up the scanning annotations. This required moving the NodeFactory used in smoke tests into a separate module.
* Small fix in Bank Of Corda demo, move Notary to Zurich so it's better displayed.
Add CashExitFlow permission to Bank Of Corda node.
* Changes in running-the-demos documentation.
* Increase max network map request size so the notary can register
* Suppress oracle service installation errors in non-oracle nodes

Change PartyAndCertificate to an aggregate class instead of a subclass of Party. This reduces the changes compared to M11, as well as avoiding risk of accidental serialization of a PartyAndCertificate (which may be very large) where a Party is expected.
Cleaned up initial nodes known to the identity service, in particular mock nodes now know about themselves; previously full nodes registered themselves but mock nodes did not.
* Fix bug in demobench. Explorer didn't show correctly location of a node.
There was no nearestCity override in config.
* Remove nearestCity from node configuration. Now information about the location is always taken from
node's legal name. If not present - exception on node startup.
* Add X500Name.locationOrNull that soft fails when location is not in X500 name. Address PR comments.
* Remove unused imports.
* 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.
Fix Bank of Corda, Trader and Notary demos.
In Notary demo, introduce deployNodes task, that deploys all three types of Notary into different directories (so there is no need to do clean, when you want to run them one after another).
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.
* 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

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.

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.
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.

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.

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.
* Document DemoBench's download link and the location of its log file.
* Document locations of DemoBench's runtime dependencies.
* Initial changes following review from Richard Brown.
* CORDA-307: Initial DemoBench documentation.
* CORDA-307: Update with review comments.
* CORDA-307: Update local installation instructions and download site.

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.
* Move merkle building extension functions on wire tx to WireTransaction class.
* Add timestamp, notary, transaction type and signers to wire transaction id calculation.
* Change construction of MerkleTree from duplicating last node on a given level to padding leaves' list with zero hash to size of the nearest power of 2 - so we always have a full binary tree.
The problem was that it was possible to construct 2 different transactions with the same ids. Trick worked for txs having number of leaves that were not power of 2.
* Update tear-offs documentation and diagrams to reflect changes in construction of Merkle trees - padding with zero hashes and including all WireTransaction fields in id computation.
* Change in filtering API of WireTransaction for partial Merkle trees calculation.
Instead of many filtering functions over a transaction only one needs to be provided.
Additional change to check and verification of FilteredTransaction.
* IRS demo change. Make filtering function a protected method of RatesFixFlow class.
Comment on situation when capturing too much scope and connected problems with checkpointing.
Change oracle and tear-offs documentation.
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.

Addressed review comments. Removed spurious buuildinfo file.
Minor changes based on richard's comments. Still waiting on resolution of dev experience preference.
Changed milestone release workflow. Users now should checkout a specific tag.
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.
Change Clause to an abstract class, and merge ConcreteClause into it. CompositeClause now
overrides defaults provided in Clause which are more suitable for composition of clauses.
Rework clauses so that rather than defining match/no-match behaviour themselves, they are
now composed by nesting them within clauses that understand how to match their child clauses.
This unifies a lot of the structure of clauses and removes corner cases needed for the first
design, as well as moving towards a model which is easier to prove.
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")
Change away from extending ClauseVerifier for contracts which support clauses, and explicitely call
clause verification code in the verify() function. This should make the flow of control easier to understand.
# The first commit's message is:
Release notes for M2
# The 2nd commit message will be skipped:

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.
Clear up wording around how the FungibleAsset superclass is used, and in particular
that it contains contract code, but provides an interface that should be extended by
subclass state objects.
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).
* Remove out of date instruction to put license text in each file.
* Add note that where parameters overflow first line, they should be one-per-line
* Add note on how TODO comments should be structured
The progress tracker API lets you model a tree of steps, along the same structure as protocols and subprotocols. Each step has an (optionally changing) label, and thus progress trackers can be arranged in a tree. Updates to the progress at each level flow up the tree via an RxJava observable (I guess we will use this more in future).
A simple console renderer is provided that uses ANSI escapes and Emoji to show animated progress through a protocol.
The trader demo is enhanced to use this framework, when run outside of Gradle.
- Fix a security bug/TODO by having seller send back the signatures rather than a full blown transaction (which would allow a malicious seller to try and confuse the buyer by sending back a completely different TX to the one he proposed)
- Introduce an UntrustworthyData<T> wrapper as an (inefficient) form of taint tracking, to make it harder to forget that data has come from an untrustworthy source and may be malicious.
- Split the giant {Buyer, Seller}.call() methods into a set of smaller methods that make it easier to unit test various kinds of failure/skip bits in tests that aren't needed.
