  • docs: integrate coverity scan, remove dead link
  • Contributors: Taehun Lim, Wonguk Jeong

0.3.1 (2022-04-27)

  • Version 0.3.1
    • inspector UI enhanced
    • unit test updated
  • foros: unittest updated add raft unittest when inspector is enabled
  • docs: inspector screenshot updated
  • Contributors: Wonguk Jeong

0.3.0 (2022-04-25)

  • docs: doxygen updated show test result using inspector not console
  • Version 0.3.0
    • inspector introduced
    • locking added for multithreading
  • foros: remove unnecessary logs
  • foros: add default period of instpector
  • foros: fill timstamp in inspector msg
  • foros: send cluster_size to inspector
  • foros: inspector implemented enable inspector with environment variables

    • FOROS_INSPECTOR : 1 to enable

    - FOROS_INSPECTOR_PERIOD : inspector message publish period if inspector is enabled, publish inspector message every FOROS_INSPECTOR_PERIOD second(s)

  • foros: add mutex for supporting multithread add mutex for

    • callback of observable
    • state transition of state machine
    • data getter/setter of context store
    • commit/revert callback of context
    • index of other node
  • docs: fix test failure of doxygen mainpage add new line at the end of foros/docs/foros.hpp

  • docs: doxygen main page added

  • Contributors: Wonguk Jeong

0.1.0 (2021-12-22)

  • foros: raft state machine TC added
  • foros: more unit TC
  • foros: unit TC added
    • add more test for cluster node class
    • add raft context, context store test cases
  • foros: refine functio signature
  • foros: raft TC added, coverage script added
  • foros: context store ldata loading bug fix
  • foros_msgs: rename fields
    • data -> entries
    • prev_data_term -> prev_log_term
    • prev_data_index -> prev_log_index
  • foros: maintain command logs by framework not user as-is: maintains command logs (data) outside (by user) to-be: maintains command logs internally using leveldb (by framework)
  • foros: maintain persistent data using leveldb election_term, voted_for, voted values should be stored in storage. (deleted on reboot) Therefore, 1) created raft context store using leveldb

    2) add options to set temp directory. default is std::filesystem::temp_directory_path() TODO: add command logs in store

  • foros: check validity of raft RPC check whether the RAFT message is sent by node which is not included in the cluster.

  • foros: quorum calculation changed as-is: calculate quorum from the number of available candidates to-be: calculate quorum from full cluster

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

  • foros: data commit API implemented

  • foros: fix method signiture mismatch

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

    • index -> id
    • term -> sub_id
  • foros: align doxygen style

  • foros: add data constructor

  • foros: specify missing const arg of function

  • 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: send current commit index in the vote request RPC

  • 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: rename callbacks of data interface

  • foros: initialize the last commit index

  • foros: add data replicatoin logic in RPC response

  • foros: the lastest data request interface added

  • foros: CommitInfo class added CommitInfo stores the index, the term, request counts. It used for storing commit information in the pending commits map.

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

  • foros: store term, request count in pending commit

  • foros: rename interfaces, add more doxygen

  • 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.

  • rename failsafe::fsros to failover::foros
