Version 2.0.3

In this release

This release basically affects order validation. It also contains fixes and improvements with a fresh Node's version dependency.

Migration

No needed.

Settings migration

1. We removed waves.dex.rest-order-limit setting. All active orders will be available via REST API order history methods.
2. Settings waves.dex.max-active-orders (our value is 400) and waves.dex.order-db.max-orders (our value is 100) added. Please, specify them.

Changes

The NODE dependency was updated to 1.1.10.

New

Orders validation

• Order fee validation was changed. So far it was possible to place buy order with received asset equals to fee asset and without sufficient balance by fee asset to cover matcher fee (if received amount would be greater than fee). Now this trick is forbidden and it is required to have sufficient balance to cover matcher fee in any case. Use gateway assets for fee payment;
• Market order validation by order book state has been weakened. Senders of market orders are not required to have sufficient balance to fully fill their order amounts. Nevertheless, its required to have nonzero balance by spendable asset and sufficient balance to cover matcher fee. Validation of the market orders price remains.

REST API

• Admin method cancelAllById has been added. It allows to cancel orders by a list of order ids;
• GET /matcher/settings - now contains matcher's public key and network byte;
• Max active and closed orders counts now can be set in appropriate settings in application.conf (in waves.dex.max-active-orders and waves.dex.order-db.max-orders respectively). Max active order count was increased to 400. Order history methods in REST API got ability to retrieve all active and closed orders.

Other

• Added support for Base58 in Waves DEX Cli.

Fixes

• GET /matcher/orderbook/{amountAsset}/{priceAsset} - loss of the query parameter depth during redirection fixed;
• GET ​/matcher​/orderbook​/{amountAsset}​/{priceAsset}​/tradableBalance​/{address} - excess assets in response fixed;
• Batch order cancel returns the latest order status;
• Saving of orders with rounding issues into Postgres history database fixed;
• After failing of storing order placement event in queue reserved balance is freed and order is removed from active ones;
• Fixed issues those led to unexpected order cancellation and wrong rejection of the order placements;
• Improved balance stream from Node. Detecting of a stream closing from the client side added.

Other changes

• We removed .travis.yml. Compilation and unit test command checkPR was renamed to quickCheck. Introduced fullCheck command to run quickCheck and integration tests too.
