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).
* Remove WorldMapLocation from NodeInfo
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
Make clearNetworkMapCache callable via RPC.
Adapt CollectSignaturesFlow to handle anonymous transactions where the keys signing commands on a transaction are not necessarily the well known identity of the participating nodes. Also prepares for any potential move away from nodes having a single primary identity by requiring flows to specify the identities they're using for a transaction.
* Hibernate session was not closed when JDBC connection was closed

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 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

Fixup after rebase
* POMs generated by publishing are now correct. The publish extension now requires an explicit call to configure the publishing instead of waiting until after evaluation. This prevents evaluation order issues with the artifact renaming code that causes the POM to have the original, incorrect, artifact names.
* Fixed new test compile issues caused by removal of some dependencies in test utils that caused webserver code to be automatically included in any project also compiling test utils.
* 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
Modify issuer flow test to verify the consumed/produced states, rather than just checking the transaction matches the value returned via the flow state machine. This is both a simpler and more relevant test.
* Cordapps now contain all explicitly specified dependencies (and sub
dependencies).
* Removed some useless compile dependencies for trader demo.
* Dependent Cordapps are excluded from the build.
:Removed unnecessary dependencies of demos.
* Cleaned up exclusion rules for cordapp dependencies.
* 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.
* 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.
* 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
Fix bug in network simulator. It failed on cast when requesting signatures from notary, now it's not a SingleMessageRecipient but InMemoryMessagingNetwork.ServiceHandle.
All references to 'parties' now refer to the inherited 'participants' attribute from ContractState.
Samples: all duplicate references to `parties` now changed to `participants`.
Display party names as common name only in IRS & SIMM samples. This doesn't change the UI where it takes in names (i.e. in IRS), as that requires significantly more infrastructure.
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
* 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.
* 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
* 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.

* Change gradle ports to match those chosen by driver
* Initial commit for CollectSignaturesFlow, some tests and associated documentation via a new "Flow Library" section of the docsite.
* Refactored the TwoPartyDealFlow to use the CollectSignaturesFlow.
* Added the subclassed CollectsigsFlow to the trader demo, whitelisted it and added a flow initiator for the responder.

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.
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.
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.
* 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.
Restructure attachment demo
Restructure attachment demo to pass the attachment hash in the transaction outputs,
rather than trying to use shared memory. Also remove 1kb test for attachments as there's little value in having a smaller test case.
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.

Event generator issues larger random amounts (10,000..1,000,000) to those than are spent (0..10,000)
Adjusted Issue (5:1) and Exit (10:1) generation frequency vs spending.
Minor fixes: added optional lockid into select for spending criteria, set notary, additional trace logging.
Generate Cash Schema by default upon node start-up (as part of NodeSchemaService initialisation).
Explicitly close JDBC statements in finally() blocks.
Tightened HibernateObserver constructor.
Fix CommercialPaper test (was missing auto-generation of CONTRACT_CASH table)
Revert default JVM size back to 200Mb.

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).
