* Rename some functions to more descriptive names
* Remove some egregious whitespace
* Revert some changes that were a dangling holdover from an aborted
refactoring - put it back how it was
* Move all alterations on the amqp schema object out of the actual
amqp/Schema file and have them live in the carpenter as extension
functions
* Move carpenter exceptions to their own file
* Rename the schema name corrupter to the name mangler
* reduce whitespace
* alter comment style
Squashed commit messages:
* Nested schema creation now works with dependencies recursvly created in
the carpenter
* Remove spurious prints from tests
* Remove warnings
* Don't add cladd member dep by name
Since that's the name of the field, not the type we depend on. If we do
we'll never actually be able to craft the type as the dependency chain
will be horribly broken
Various bug fixes
* Fix merge issue where types weren't being seen as Prims
* IntelliJ auto code cleanup / reformat
* Whitespace changes
* Add comment blocking as I like seeing it in files
A complete amqp schema can now be used to generate a set of carpetner
schemas representing all of the classes not found on the deserialzing
end.
A dependency and depdendent chain is setup such that all classes are
created in the order required
Squashed commit messages:
* IntelliJ reformat of the code

Various bug fixes
Unit tests that pull out the envelope from a deserialsed object (which
we have already serialised) then using the AMQP schema contained within
convert that to a carpenter schema and build an object
Currently testing only simple classes with a single type member
Squashed merge commits:
* Fix for the type issue in the SerializerFactory
Needs to pull in the actual Java types otherwise we use the Kotlin types
as the map keys which will never correspond to the java types that the
wrapper wraps around the primitive before doing a map lookup
Boolean just doesn't seem to work as pulling that in starts breaking
Kotlin and Character also seems broken. There is a fix for this also on
Rick's branch so pushing this in for now and can use his actual changes
when they're available on Master
* Better tests
* Add support for sub classes known to the JVM
* Initial work towards integrating serializer with the carpenter

* Switch to using anonymous party as recipient
* Enable anonymisation for issuance as well as move in issuer flows.
* Pass notary into issuer flow rather than taking a notary at random from the network map.
* Enable anonymisation in Bank of Corda RPC test
* Parameterize issuer flow tests into anonymous and deanonymised versions
For testing I need to be able to mess with the schema before it gets
added to the envelope, extract the function where that happens and make
it open so the tests can do what they want
* Pagination improvements (fail-fast on too many results without pagination specification)
* Fix incorrectly returned results count.
* Performance optimisation: only return totalStatesAvailable count on Pagination specification.
* Changed DEFAULT_PAGE_NUMBER to 1 (eg. page numbering starts from 1)
* Changed MAX_PAGE_SIZE to Int.MAX_VALUE
* Fixed compiler WARNINGs in Unit tests.
* Fixed minimum page size check (1).
* Updated API-RST docs with behavioural notes.
* Updated documentation (RST and API);
* Provide sorting by state reference (and individual constituents of: txId, index)

* Fix missing imports after rebase from master.
* Fix errors following rebase from master.
* Updates on expression handling following feedback from RP.

* Correct registration of transaction key flows
* Move TransactionKeyFlow.Provider into CoreFlowHandlers
* Move TransactionKeyFlow.Request up to the top level class instead of being a class within an object.
* Remove AbstractIdentityFlow and move the validation logic into individual flows to make it clearer that it's registering the received identities.
* Cash flows now return the recipient identity instead of full identity lookup, as this is what
the caller actually needs and simplifies a lot of cases.
Remove prohibition against non string object classes such as arrays
Squashed Commmits:
* Tidyup whitespace
* WIP
* Review Comments
* WIP - adding concept of nullabltily into the carpenter
* Add explicit nullable and non nullable fields
* Rebase onto master, fix package names in carpenter
* Fix https://github.com/corda/corda/issues/949 by providing a default StateStatus argument to all QueryCriteria types.
* Abstracted Common Criteria into its own abstract data class + associated visitor.
* Incorporating feedback from RP PR review.
Remove use of Sun internal APIs and algorithm identifiers (which are incomplete and non-standard) in Crypto. Also eliminates uncertainty about which signature scheme is being used (and therefore iterating through several to find the correct one).
* Add functions for:
* Retrieving nodes via their legal identity
* Filtering a set of public keys down to those the node has corresponding private keys for
* Modify contract upgrade flows to handle identifying participants after an anomymisation step
* Correct terminology: "party who" -> "party which"
* Modify CashIssueFlow and CashPaymentFlow to optionally use an anonymous identity for the recipient.
* Replace kotlin Pair with DataFeed data class
* remove unintended changes
* Replace Vault.PageAndUpdates with DataFeed data class
* Remove PageAndUpdates
* First stage of changing fields in NodeInfo.
Part of work related to NetworkMapService upgrade. Create slots for
multiple IP addresses and legalIdentities per node.
* NodeInfo stores HostAndPort.
Move information specific to messaging layer away from NodeInfo.
Only HostAndPort addresses are stored. Add peer name - peer handle
mapping to MockNetwork to reflect that change.
* Enforce that the identity service must always have a root CA specified, which all identities have
certificates signed by (or intermediaries of). Also adds a certificate store to the identity service
for help building/verifying certificate paths.
* Add a certificate store for the CA certificate and intermediaries
* Use the certificate factory directly to build paths rather than assembling them via an interim
API call. After reducing the complexity of the utility API, it's replacing two lines of code,
at which point it seems better to make the behaviour clearer rather than having a function
hide what's actually going on.
Added Kotlin extension functions for ease of use in simplest case.
Added missing Java contractType class (previously was forced cast of ContractState::class)
Fixed generic typing.
Addressed items raised in SA PR review.
Removed 2 blank lines.
Fixed generics typing.
Updates RST doc and grouped API helpers accordingly.

Revert unrelated changes.
PR review updates: blank lines, isRelevant.
Fixed wiring of updatesPublisher for dynamic trackBy queries.

* Minor fix following rebase from master.
* Remove blank line as per RP PR feedback request.
* Minor Java documentation and example clean-up.
* Disable BFT Notary Service tests.
* The fancy classloader setup in Cordform.loadCordformDefinition is defeated by certificates in 2 ways
** Class cast when creating a cert (via TestConstants) in a CordformDefinition
** Some issue when persisting a cert in ServiceIdentityGenerator
* This PR is a quickfix to get the demos working again
* Proper fix (not this PR) is to work out why it's not enough for eddsa to be in the project runtime classpath - if it can be removed from the gradle environment that ought to properly fix the above problems
Use the certificate factory directly to build paths rather than assembling them via an interim
API call. After reducing the complexity of the utility API, it's replacing two lines of code,
at which point it seems better to make the behaviour clearer rather than having a function
hide what's actually going on.
Add extremely rough DER format encoding for CompositeKey so that they can be used in X.509 certificates,
and switch service identity generator to using the proper identity cert for signing.
* Fix BFT config that only worked with clusters of size 4
* Shutdown BFT properly so that tests can run back to back in theory
* Wait for initial connection between client and all replicas before touching it
* Add test for non-trivial BFT cluster
* Shutdown NodeBasedTest nodes in parallel, as BFT shutdown time is non-trivial
* Overlapping ports check no longer assumes all on localhost
* Fix overlapping ports test to actually check the messages
* Correct path composition in identity service tests
* Correct identity service certificate path verification to handle the owning certificate being anywhere in the path, rather than expecting it to be trust root
Correct construction of anonymous parties to use the first certificate (the target)
rather than the last (the trust root). Worked because early tests used single certificate
paths, but later work introducing multi-certificate paths reveal it's rather broken.
* Remove unused type param
* If we drop Runnable we can use conciser syntax
* Sometimes we need the fully-fledged object, so retire separate handle class
* Implement IntelliJ suggestion
Deterministic Key Derivation for ECDSA R1/K1 and EdDSA
* DKG description and comments
* Removing a (confusing) not-required comma in comments.
* rename deterministic and generate to derive
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.
Modify generateExit to return full set of signing keys in preparation for anonymity work meaning
that owner and issuer keys are typically not the same.
All references to 'parties' now refer to the inherited 'participants' attribute from ContractState.
Samples: all duplicate references to `parties` now changed to `participants`.
Clean up cash tests ahead of anonymisation work. This simplifies some boiler plate setup/teardown
and ensures idenities and flows are correctly registered.
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.
Core corda publications and JARs now have cord or corda at the start (excluding gradle plugins). Removed an unnecessary dependency on test-utils in node-schemas to prevent an evaluation order bug in gradle.
* Increase max network map request size so the notary can register
* Suppress oracle service installation errors in non-oracle nodes
* Make demos automatically build capsule jars
* Fix how network visualiser displays node X500 names.
* Change locations of test nodes, so when used for explorer map visualisation not all of them are stacked one on another in London.
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.
* Specifically, DriverTests and WebserverDriverTests
* RPCDriver.startRpcBroker now waits for port to be unbound, as was probably intended
* Explicitly drop network map future while ensuring the error is logged
* 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.
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
* Add "TLS" to createTlsServerCert() to differentiate it from future work to introduce a non-TLS variant.
*Change to using Java 8 time types for certificate validity - does introduce so unnecessary roundtrips, but makes the code significantly easier to read/follow. In particular avoids opaque integers in the code and replaces them with Duration.
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.

* Addressed Sham's comments.
* Rebased to M11.
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 API documentation (including coding snippets and examples).
* Added @JvmOverloads to QueryCriteria classes for easy of use from Java.
* Refactored QueryCriteria API to use composition via sealed data classes.

* Fixed typo.
* Clarified future work to enforce DB level permissioning.
* Moved PageSpec and Order from QueryCriteria to become parameters of Query itself.
* 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.
Clean up X500 names in Corda simulation, and ensure they're consistent with the standard test names.
This includes using the locations present in those test names, which requires updates to the node
config test.
* Fix /attachments endpoint on WebServer, and update demo to use it.
* Add @Throws statements to servlet methods.
* Ensure target entry is not a directory.
* Simplify, because JarInputStream verifies signatures by default.
* Move JarInputStream.extractFile() function into core.
* Don't close the output stream automatically as it commits our response.
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.
* 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.
DemoBench: Misc usability improvements:
- Pre-fill details for some fictional banks when Add Node is pushed.
- Make services a checkbox list rather than one where you have to know how to use the keyboard to do multi-select.
- Make web server launch button spin until server is launched to show activity.
- Suppress an exception that spams the log due to inability to load all the states. It'll get fixed as part of the vault API and serialisation work.
* 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.
Assuming that Autocomplete will be added, according to JIRA https://r3-cev.atlassian.net/browse/CORDA-367
Note that there are still a few duplicates in the source with slightly different coordinates. I assume the autocomplete will be able to cope, or these can be removed.
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.
