201803ff36 Now runs Java CommercialPaper unit tests 
Acted upon comments from last pull request.
Added an interface to enable the usage of the same tests for both the Kotlin and Java example CommercialPaper class - did appropriate refactoring to enable.
Added javadoc, removed public modifier from interfaces.
Various fixes from code review comments.

1e8ea8eb2c Implement the beginnings of a serving node. 
It uses Artemis (an embeddable MQ broker) and can run in either a 'serving' mode, in which case it will sit around waiting to sell fake commercial paper assets, or a 'buying' mode in which case it will connect to a specified serving node and run the two party trade protocol.

Most services are either mocked out or too trivial to be useful at this point. They will be fleshed out in the future.

78849f44d2 Protocols: simplify the two party (dvp) protocol some more, now that we've switched to Quasar. There's no longer any need to define InitialArgs objects. 2016-01-12 12:14:45 +01:00
Mike Hearn
c59603c26f Implement timestamping as a separate service that the two party (dvp) protocol calls out to via a simple client object. 
Lots of big changes in this commit:
* Introduction of "network map" and "legally identifiable node" concepts to the networking abstraction.
* State machines framework now lets you send messages to multiple different destinations in the same protocol.
* Timestamping service that can run inside a node is now implemented and unit tested.
* Starting to benefit from the improvements in Quasar (the initialArgs concept can mostly be got rid of now, etc)

412212a860 Switch from JavaFlow to Quasar to provide fibers. 
Quasar is a more modern, better maintained and more powerful framework. The main improvement is that this lets us avoid the ClassLoader tricks that JavaFlow was requiring, by using an agent. This introduces a requirement to mark methods that might be on a suspended stack as @Suspendable, but means that code interops cleanly. In Java 9 it is hoped that the marking requirement may even go away entirely.

31fbf5e1eb Improve the transactions API a small amount with lazily deserialized access to the WireTransaction inside a SignedTransaction, and id/hash fields (again lazily calculated). 
This required bringing back the ImmutableClassSerializer and registration of classes that need it, to ensure the constructors run.

049f0aa3b3 Rename PartialTransaction -> TransactionBuilder. The term "partial transaction" should be reserved to mean a transaction that is lacking some signatures as it's in the process of being built up by multiple parties. 2015-12-22 15:28:38 +00:00
Mike Hearn
bcc56859af Add a unit test to check before/after processing by the dummy timestamper. 
Tweak the timestamping API a bit.
 2015-12-22 15:03:11 +00:00
Mike Hearn
784452ac50 Reorganise how time is handled: timestamping authorities are now oracles who sign the entire transaction. 
As a result, TimestampedWireTransaction is gone. Timestamp fields are gone. Timestamp commands contain before/after fields. The notion of time tolerance is now a part of the timestamping interface and timestamp data.

TODO:
- Unit tests to verify the notBefore/notAfter logic
- Documentation update

65c5fa7502 Messaging: (mock) in memory network implementation improvements. 
- Now supports simulated restart of nodes
- Messages sent to non-running nodes are queued for delivery
- Messages received by a node that don't match any topics are queued until handlers are registered

These improvements help us unit test various robustness features and ensure things work in truly concurrent context where there can be race conditions like receiving a message before the node had a chance to register the right handlers.

7881be07ed Delete a lot of Kryo/serialisation related boilerplate. 
This is/was an attempt to be secure against malicious streams, but as Kryo is just a temporary bit of scaffolding and isn't intended to be actually used in any real product, it was just a waste of time and the registration requirement was getting increasingly awkward.

73cbd41a09 Misc fixes: 
- Use the OpaqueBytes wrapper (a box for byte[]) inside TimestampedWireTransaction to avoid array comparison issues.
- Introduce a few utility functions to make OpaqueBytes less painful.
- Make StateAndRef serialisable
- Introduce the notion of an OwnedState which abstracts out the owner field.
