In this release

This release contains a new NODE support and a lot of improvements, including the lower latency observed by our load tests.

See below for more information.

Migration

Recommended to do the snapshot on all Matcher servers before update:

curl -X POST -H 'X-Api-Key: your-api-key-here' "http://host:port/matcher/debug/saveSnapshots"

New

  • Support of NODE 1.2.9;
  • Showing an order version for new orders at order history HTTP endpoint;

Huge improvement of Swagger documentation

  • Most methods are provided with examples of entities, both input and output;
  • Models are provided. They also contain a useful documentation, for example, how to sign the request;
  • Added a grouping by purpose.

WebSocket improvements

API changes are still possible, so we don't expose the documentation right now.

  • Clients now receive the MatcherIsStopping error during the graceful shutdown;
  • Scheduling optimizations, which leads to less pressure on the server;
  • Fixed some cases in which matcher sent exceed data to the client.

Fixes

  • Fixed the calculation of the average weighed price of an order;
  • ExchangeTransaction should not be created if a market order wasn't matched at least on 1 coin;
  • Returning a meaningful error, when a user passes an address from another network;
  • If the order wasn't matched, the average weighed price is 0;

Other changes

  • Scala is updated to 2.13, also updated a lot of dependencies;
  • A lot of improvements in the checker utility. It checks that matcher works correctly after update;

Initial support for Docker

We made huge steps to provide Docker images. Now they are in review, but we are already use them in our functional testing.

  • Images wavesplatform/matcher-node (Waves Node with Extension) and wavesplatform/matcher-server (DEX) introduced;
  • Draft of the README.md updates added: README_DOCKER.md. Use it at own risk;
  • An image of NODE with Matcher extension for functional testswaves-integration-it is built upon matcher-node;
  • An image of Matcher server for functional tests dex-it is built upon matcher-server;

Code improvements

Usually we don't mention an internal changes. But there were made a lot of code improvements, so we notice them.

  • A better packages and class names;
  • More unit tests for REST API, added a backward compatibility tests for JSON encoding;
  • Introduced REST API DTO annotated objects, this will add an additional level of API stability;
  • Serialized representation of Waves, Order Statuses, Order Types and Accepted Order Types unified across the project.
