0.1.0 (2021-12-22)

• foros_examples: add missing dependency std_msgs dependency added in package.xml, CMakeLists.txt

• foros_examples: log replication test updated

  • "clsuter_log_replication_with_commit" commit every 1 sec
  • "cluster_log_replication_withou_commit" check replication by callback

• foros_example/cluster_service: support test with given cluster size

• foros_example/cluster_publisher: support test with given cluster size

• foros_examples/cluster_election: support test with given cluster size

• foros: use rclcpp logger not std::cerr, std::cout

• foros: data commit API implemented

• foros: refine cluster node data itnerface Do not use internal terminology in APIs

  • index -> id
  • term -> sub_id

• foros: update commit index, next index as needed

  1) update last commit index,

  • on local commit

  - on rollback commit

  2) update next indeice of other nodes, when the node becomes leader

• foros: data replication logic added (phase 1)

  • implemented replication using broadcast

  - example added TODO:

  • bug fix
  • implement replication using data commit API

• foros: add lifecycle callback register APIs The virtual function is not guarenteed to be invoked in the constructor. Therefore, uses register APIs not overriding As-Is: overriding using interface To-Be: register using API explicitly

• foros: add data replicatoin logic in RPC response

• fsros: add prev commt info in Data class To achieve raft data duplication, need to pass previous commit index and previous commit term.

• foros: data commit interface added for data replication,

  1) add data interface API 2) data commit API added in raft context

• foros: align coding style (CommitData, CommitResponse)

• foros: change commit data API to asnyc API This API need to make a consensus in the cluster. Therefore, change to async API.

  • use promise-future

  - for now, return result immediately until the business logic is implemented.
