6cb86ab840 Plumb attachments through to the contract verify functions (no contract uses them yet). 
The right way to do this is probably to put the contracts onto the classpath before execution of the contract. However, this interacts closely with the sandboxing work, which isn't yet started, so for now this will do.

c3f86f6557 Integrate a simple progress tracking system into the protocol framework. 
The progress tracker API lets you model a tree of steps, along the same structure as protocols and subprotocols. Each step has an (optionally changing) label, and thus progress trackers can be arranged in a tree. Updates to the progress at each level flow up the tree via an RxJava observable (I guess we will use this more in future).

A simple console renderer is provided that uses ANSI escapes and Emoji to show animated progress through a protocol.

The trader demo is enhanced to use this framework, when run outside of Gradle.

1243ca2066 Trading: in the two party trade protocol, check that the proposed transaction is contract-valid, and that the missing signatures are what is expected. 2016-02-17 18:38:24 +01:00
Mike Hearn
cd28733360 Major: Separate out the dep resolution protocol into a couple of sub protocols and use on both sides of the trade. 
* Dependency resolution/checking is now working on both sides of the two party trading protocol.
* The commercial paper contract was changed to check timestamping authority identities by name instead of key.
* The trader demo has been rewritten to use the protocol framework, which simplifies the code.

d98a3871da Refactor the 2-party trading protocol 
- Fix a security bug/TODO by having seller send back the signatures rather than a full blown transaction (which would allow a malicious seller to try and confuse the buyer by sending back a completely different TX to the one he proposed)
- Introduce an UntrustworthyData<T> wrapper as an (inefficient) form of taint tracking, to make it harder to forget that data has come from an untrustworthy source and may be malicious.
- Split the giant {Buyer, Seller}.call() methods into a set of smaller methods that make it easier to unit test various kinds of failure/skip bits in tests that aren't needed.

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.

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.
