9758023 apis/database: Fix ContentMetadata UnmarshalJSON

Summary

transports/websocket has been rewritten from scratch.

It uses github.com/sourcegraph/jsonrpc2 and github.com/gorilla/websocket now.

The transport package should be more robust. The code is much less messy and it uses up-to-date packages.

The transport API is also changes. You can now pass multiple WebSocket endpoint URLs and the auto-reconnect logic will use round-robin to rotate between the URLs provided.

f4bba9c transport/websocket: Rewrite from scratch

Summary

Improved types.Authority to be actually a map. That is how it is defined in steemd.

This is a breaking change, sorry.

Commits

79c5181 types: Improve type Authority
480ea8d types: Add StringInt64Map

Summary

Basically reverted the previous release, added types.CommentOperation.JsonMetadata as a string field.

Commits

86fb422 types: Add CommentOperation.JsonMetadata 57b3a4f Revert "Add CommentOperation.JsonMetadata"

Summary

Added CommentOperation.JsonMetadata. Had to move ContentMetadata from apis/database into types, hence the version number incremented.

Commits

efaa109 Add CommentOperation.JsonMetadata

Summary

Added Client.Database.GetOpsInBlock.

b923545 apias/database: Add GetOpsInBlock
bf16641 apis/db: Add GetOpsInBlockRaw
c534224 examples/upvote: Update README

Summary

This is a very exciting release since from now on go-steem/rpc supports signed transactions! This means that it is not only possible to read data from the blockchain, you can broadcast new transactions as well!

See examples/upvote for an example how it all works.

Please note, though, that the transaction API is totally new and it is possible that it will be cleaned and refactored in the future to make SignedTransaction nicer to use.

Roadmap

For the next release I would like to focus on cleaning up the existing API, particularly considering transactions.

Summary

Operation unmarshalling was largely remade and improved. Many more operations are now supported natively as statically typed Go structs. This includes CustomJSONOperation, which also has some superpowers to parse the embedded JSON and return relevant Go struct as well.

Full support for login_api and partial support for follow_api was added.

Other than that there have been numerous bugfixes related to wrong JSON unmarshalling.

Summary

This release includes multiple breaking changes. Basically the whole package was heavily refactored.

The major changes are following:

• The way the RPC client is created is different now. You don't pass a URL into the constructor, but rather a transport implementation that is then used by the client internally.
• Since there are multiple APIs exposed via the RPC endpoint, the database api, that is the only API supported so far, is not accessible on the client object itself any more, you need to use client.Database, i.e client.Database.GetConfig() instead of client.GetConfig().
• The WebSocket transport now supports auto-reconnect mode. When enabled, the transport will try to reconnect automatically when the connection is not there yet or it is lost. The transport is also emitting events so that it is possible to see whether the underlying connection is established or not.
• It is also possible to set WebSocket connection read and write timeouts.

Most of the changes are visible in examples/voting_monitor, except connection deadlines.

MVP release of go-steem/rpc.
