UNRELEASED
|
||||
----------
|
||||
|
||||
* A new RPC has been added to support fuzzy matching of X.500 names, for instance, to translate from user input to
|
||||
an unambiguous identity by searching the network map.
|
||||
|
||||
* The node driver has moved to net.corda.testing.driver in the test-utils module
|
||||
|
||||
* Enable certificate validation in most scenarios (will be enforced in all cases in an upcoming milestone)
|
||||
|
||||
* Added DER encoded format for CompositeKey so they can be used in X.509 certificates
|
||||
|
||||
* Corrected several tests which made assumptions about counterparty keys, which are invalid when confidential identities
|
||||
are used

Milestone 13
|
||||
------------
|
||||
----------
|
||||
Special thank you to `Frederic Dalibard <https://github.com/FredericDalibard>`_, for his contribution which adds
|
||||
support for more currencies to the DemoBench and Explorer tools.
|
||||
|
||||
* Web API related collections ``CordaPluginRegistry.webApis`` and ``CordaPluginRegistry.staticServeDirs`` moved to
|
||||
``net.corda.webserver.services.WebServerPluginRegistry`` in ``webserver`` module.
|
||||
Classes serving Web API should now extend ``WebServerPluginRegistry`` instead of ``CordaPluginRegistry``
|
||||
and they should be registered in ``resources/META-INF/services/net.corda.webserver.services.WebServerPluginRegistry``.
|
||||
* A new Vault Query service:
|
||||
|
||||
* Implemented using JPA and Hibernate, this new service provides the ability to specify advanced queries using
|
||||
criteria specification sets for both vault attributes and custom contract specific attributes. In addition, new
|
||||
queries provide sorting and pagination capabilities.
|
||||
The new API provides two function variants which are exposed for usage within Flows and by RPC clients:
|
||||
- ``queryBy()`` for point-in-time snapshot queries
|
||||
(replaces several existing VaultService functions and a number of Kotlin-only extension functions)
|
||||
- ``trackBy()`` for snapshot and streaming updates
|
||||
(replaces the VaultService ``track()`` function and the RPC ``vaultAndUpdates()`` function)
|
||||
Existing VaultService API methods will be maintained as deprecated until the following milestone release.
|
||||
|
||||
* The NodeSchema service has been enhanced to automatically generate mapped objects for any ContractState objects
|
||||
that extend FungibleAsset or LinearState, such that common attributes of those parent states are persisted to
|
||||
two new vault tables: vault_fungible_states and vault_linear_states (and thus queryable using the new Vault Query
|
||||
service API).
|
||||
Similarly, two new common JPA superclass schemas (``CommonSchemaV1.FungibleState`` and
|
||||
``CommonSchemaV1.LinearState``) mirror the associated FungibleAsset and LinearState interface states to enable
|
||||
CorDapp developers to create new custom schemas by extension (rather than duplication of common attribute mappings)
|
||||
|
||||
* A new configurable field ``requiredSchemas`` has been added to the CordaPluginRegistry to enable CorDapps to
|
||||
register custom contract state schemas they wish to query using the new Vault Query service API (using the
|
||||
``VaultCustomQueryCriteria``).
|
||||
|
||||
* See :doc:`vault-query` for full details and code samples of using the new Vault Query service.
|
||||
|
||||
* Identity and cryptography related changes:
|
||||
|
||||
* Enable certificate validation in most scenarios (will be enforced in all cases in an upcoming milestone).
|
||||
|
||||
* Added DER encoded format for CompositeKey so they can be used in X.509 certificates.
|
||||
|
||||
* Corrected several tests which made assumptions about counterparty keys, which are invalid when confidential
|
||||
identities are used.
|
||||
|
||||
* A new RPC has been added to support fuzzy matching of X.500 names, for instance, to translate from user input to
|
||||
an unambiguous identity by searching the network map.
|
||||
|
||||
* A function for deterministic key derivation ``Crypto.deterministicKeyPair(privateKey: PrivateKey, seed: ByteArray)``
|
||||
has been implemented to support deterministic ``KeyPair`` derivation using an existing private key and a seed
|
||||
as inputs. This operation is based on the HKDF scheme and it's a variant of the hardened parent-private ->
|
||||
child-private key derivation function of the BIP32 protocol, but it doesn't utilize extension chain codes.
|
||||
Currently, this function supports the following schemes: ECDSA secp256r1 (NIST P-256), ECDSA secp256k1 and
|
||||
EdDSA ed25519.
|
||||
|
||||
* A new ``ClassWhitelist`` implementation, ``AllButBlacklisted`` is used internally to blacklist classes/interfaces,
|
||||
which are not expected to be serialised during checkpoints, such as ``Thread``, ``Connection`` and ``HashSet``.
|
||||
This implementation supports inheritance and if a superclass or superinterface of a class is blacklisted, so is
|
||||
the class itself. An ``IllegalStateException`` informs the user if a class is blacklisted and such an exception is
|
||||
returned before checking for ``@CordaSerializable``; thus, blacklisting precedes annotation checking.
|
||||
|
||||
* ``TimeWindow`` has a new 5th factory method ``TimeWindow.fromStartAndDuration(fromTime: Instant, duration: Duration)``
|
||||
which takes a start-time and a period-of-validity (after this start-time) as inputs.
|
||||
|
||||
* The node driver has moved to net.corda.testing.driver in the test-utils module.
|
||||
|
||||
* Web API related collections ``CordaPluginRegistry.webApis`` and ``CordaPluginRegistry.staticServeDirs`` moved to
|
||||
``net.corda.webserver.services.WebServerPluginRegistry`` in ``webserver`` module.
|
||||
Classes serving Web API should now extend ``WebServerPluginRegistry`` instead of ``CordaPluginRegistry``
|
||||
and they should be registered in ``resources/META-INF/services/net.corda.webserver.services.WebServerPluginRegistry``.
|
||||
|
||||
* Added a flag to the driver that allows the running of started nodes in-process, allowing easier debugging.
|
||||
To enable use `driver(startNodesInProcess = true) { .. }`, or `startNode(startInSameProcess = true, ..)`
|
||||
to specify for individual nodes.
|
||||
|
||||

|
||||
* Upgraded Kotlin to v1.1.2.
|
||||
* Upgraded Dokka to v0.9.14.
