495e870b74 NodeInfo remove main identity (#1284)
* Remove node's main identitiy from NodeInfo.

Preparation for getting rid of services + supporting multiple identities
on the node.
NodeInfo keeps multiple identities as a list. For now the first one is treated as a special one.
Introduced function chooseIdentity in CoreTestUtils as a preparation for proper handling of multiple identities in the future.
Remove legalIdentityKey from ServiceHub, add extension function - chooseIdentity on ServiceHub.
Add `me` field on FlowStateMachineImplemetation, flows should know what the calling identity is.
Remove SERVICES_PREFIX in artemis messaging layer.

* Address minor comments.

* Fixes after rebase.

Remove chooseIdentity from ServiceHub

* Rename me to ourIdentity on FlowLogic

* Fixes after rebase

* Address Ross comments, fixes

* Fix after rebase

* Fix services certificate paths

Apply Patrick's patch.

3d577e5eed CORDA-499: Remove further Kt classes (#1489)
* Change how NetworkHostAndPort is parsed

Change from using a global extension function to parse
NetworkHostAndPort strings, into using a function on the companion
object. This is a lot easier for Java interop and matches the common
style used elsewhere both in Corda and in Java libraries.

* Move JAR extraction into new utils file

* Move path verification function to ArtemisUtils

Move path verification function "requireOnDefaultFileSystem()" to new
ArtemisUtils.kt file, as this makes more sense from a Java interop
perspective.

* Add JvmName to AMQPSchemaExtensions

* Add JvmName to AMQPSerializationScheme

* Revert "Move JAR extraction into new utils file"

This reverts commit 1f0f41909b68ff21cc24b5efd6a1a360393a0a14.

* Reformat code

* Run formatter on ArtemisUtils

ef409c4d65 CORDA-539 - Fix for attempting to create a primitive nullable field
Refactoring meant that the secondary constructor wasn't being called any
more and thus the check wasn't being made. Originally, we always
created copies of fields when constructing a schema which meant we always
called the secondary constructor, now we don't

a829dfadaa Bring enum serializer into line with AMQP
AMQP doesn't define an enum type itself yet the old implementation
listed our snum type as that in the schema despite what we are actually
doing which is serialising the enum down as a list of a string and an
int accompanied by a list of AMQP choices that represent all of the enum
values

Review Comments

include the enum constants in the fingerprint to avoid any collisions

1e023fcf54 Add alt serialise method that returns the schema and the bytes

this in the same way we can for deserialize

299b8026c7 Add constructor annotation for evolve selection
Current implementation is such that if we find *a* constructor that
works for us we use that, this is of course rather non deterministic, it
also means we may not select the best constructor

for example

old versions had constructors that took

V1: A B
V2: A B C D

if current version, V3 is

V3: A B C D E

which provides secondary constructors for the above then there is a
chance we'd de-serialise objects that were serialised as V2 using the V1
constructor and thus throw away information we don't need to

Additional Changes:

Fixes following rebase onto master

1d131eced5 Add Evolvability to Serializer
If we attempt to deserialize a class and find that since it's
serialization the definition has changed we need to create a serializer
capable of evolving the serialised data and constructing an instance of
the new type

We currently cope with

* Removing members
* Adding nullable members
* Adding non nullable members if a constructor is provided that
  allows us to set the old arguments and defaults the new (mandatory)
  fields
* Reordering paramters

Hibernate entities require explicit call to flush() to persist to disk.

* Removed redundant requery converters (equivalents not even required in Hibernate).

* Removed remaining gradle requery dependency definitions.

* Fixed broken tests.

* Fixes for failing NodeVaultService tests:
- Dynamic SQL updates (in soft locking code)
- Explicit request by session to participate in transaction (causing "TransactionRequiredException" Executing an update/delete query)
- Explicit flush() required to persist to disk

* Updated changelog.

* Fixed WHERE clause AND/OR condition.
Enforced immediate data visibility through transaction commit.

* Final fixes to address failing tests.

* Deferred all hibernate session/txn management to DatabaseTransactionManager.

* Fixed transaction boundaries in failing Cash tests.

* Fixes to address failing tests (transaction boundaries, merge detached object, config clean-up).

* Final adjustment to transaction boundaries in JUnit tests.

* Refactored AttachmentSchemaV1 into NodeAttachmentService itself and referenced from NodeServicesV1.

* Refactored HSQL UPDATE statements to use CriteriaUpdate API.

* Updated all criteria API getters to reference attribute names by type.

* Remove redundant VaultSchema entity name (required when previously using HSQL UPDATE syntax)

1f9c04544d Make the carpenter a member of the serialiser factory
If it's not then the caroenter's class loader isn't persistent and thus
we will be constantly recarpenting objects

45ed78b1a8 Serialiser / Synthesiser work and cleanup
- Adding test case that shows it should work
      AS it works with concrete classes, not if we carpent up the back end
    - WIP
    - The current test fails because the carpenter is creating the map (for
      some reason) as a linked hash map and not a normal map that we can't
      serialise. Added a test to confirm that it's not the carpenter here.

      Two questions really, why are we creating it as a linked has map, AFAIK
      the carpenter should just be whipping up what it's told to and it's not
      being given a linked map

      Secondly, should we support serialisation of these objects

    - Remove debug
    - Remove yet more debug

92ba0c33e1 Adding more / better tests, splitting existing tests up
Squashed commit messages
    - Split up the serialiser/synthesiser tests into more manageable sizes
    - WIP - found test which breaks deserialiser
      Looks to be soemthign to do with synthesising a class with a container
      of Interfaces

4cfa376d7d Add the carpenter into the deserializer
Deseializing any blob that contains a type unknown to the classloader
will cause a class object to be carpented up and a suitable object
returned
