  • 🛠 [bugfix] asio: more correct timers cancellation implementation

• v0.10 Changes

  November 09, 2020

  • [improvement/breaking] Generic timers interface
  • 👍 [improvement] Request cancellation support
  • [improvement] added make_response methods when message should be created, but
    send later delayed
  • 🔌 [improvement] more debug information in message delivery plugin
  • 📚 [documentation] Integration with event loops
  • 📚 [documentation] Requests cancellation and timers are demonstrated in the
    📄 Advanced Examples section
  • [example] examples/boost-asio/ping-pong-timer.cpp (new)
  • ⚡️ [example] examples/boost-asio/beast-scrapper.cpp (updated)
  • 🛠 [bugfix] avoid double configuration of a plugin in certain cases when interacting
    🔌 with resources plugin
  • 🛠 [bugfix] more correct cmake installation (thanks to Jorge López Tello, @LtdJorge)

• v0.09 Changes

  October 03, 2020

  • 📚 [improvement] rewritten whole documentation
  • 🔌 [improvement/breaking] plugin system where introduced for actors instead of
    behaviors
  • [improvement] actor_config_t was introduced, which now holds pointer to
    supervisor, init and shutdown timeouts
  • 🏗 [improvement] builder pattern was introduced to simplify actors construction
  • [breaking] supervisor_config_t was changed (inherited from actor_config_t)
  • [breaking] actor_base_t and supervisor_t constructors has changed - now
    appropriate config is taken as single parameter. All descendant classes should
    be changed
  • [breaking] if a custom config type is used for actors/supervisors, they
    should define config_t inside the class, and templated config_builder_t.
  • [breaking] supervisor in actor is now accessibe via pointer instead of
    refence
  • [bugfix] supervisor_ev_t not always correctly released EV-resources, which
    lead to leak
  • [bugfix] actor_base_t can be shutted down properly even if it did not
    started yet

• v0.08 Changes

  April 12, 2020

  • 🛠 [bugfix] message's arguments are more correctly forwarded
  • 🛠 [bugfix] actor's arguments are more correctly forwarded in actor's
    creation inrotor::supervisor_t and rotor::asio::supervisor_asio_t
  • 🛠 [bugfix] rotor::asio::forwarder_t now more correctly dispatches
    boost::asio events to actor methods; e.g. it works correctly now with
    async_accept method of socket_acceptor

• v0.07 Changes

  April 02, 2020

  • [improvement] more modern cmake usage

• v0.06 Changes

  November 09, 2019

  • [improvement] registy actor was added to allow via name/address runtime
    matching do services discovery
  • [improvement, breaking] minor changes in supervisor behavior: now it
    is considered initialied when all its children confirmed initialization
  • [improvement] supervisor_policy_t was introduced to control supervisor
    behavior on a child-actor startup failure
  • [example] examples/ev/pong-registry.cpp how to use registry
  • [doc] patterns/Registry was added

• v0.05 Changes

  September 22, 2019

  • [improvement] response can be inherited from rotor::arc_base, to allow
    forwarding requests without copying it (i.e. just intrusive pointer is created)
  • [example] examples/boost-asio/beast-scrapper.cpp has been added; it
    👷 demonstrates an app with pool of actor workers with request-response forwarding

• v0.04 Changes

  September 13, 2019

  • 👍 [improvement] the [request-response] approach is integrated to support basic
    [reliable] messaging: response notification failure will be delivered,
    if the expected response will not arrive in-time
  • 👍 [improvement] lambda subscribiers are supported
  • [improvement] actor behavior has been introduced to offload actor's
    interface
  • [breaking] supervisor is constructed with help of supervisor_config_t,
    ⏱ which contains shutdown timeout value
  • ⏱ [breaking] supervisor does not spawns timeout timer for overall shutdown
    procedure, instead per-child timers are spawned. The root supervisor
    the same way monitors child-supervisor shut down
  • [breaking] supervisor create_actor method now takes child max
    init time value. If it does not confirm, the child actor will be asked
    for shut down.
  • ⏱ [breaking] shutdown request sent to an child actor now timeout-tracked
    by supervisor. The message type has changed to message::shutdown_request_t
  • ⏱ [breaking] init request sent to an child actor now timeout-tracked
    by supervisor. The message type has changed to message::init_request_t
  • [breaking] actor's state request message type now message::state_request_t,
    which follows the generic request/response pattern. The response type
    is now message::state_response_t.
  • [breaking] {asio, ev, ws} supervisor configs are renamed to have
    corresponding suffix.

• v0.03 Changes

  August 24, 2019

  • [improvement] locality notion was introduced, which led to possibilty
    🏗 to build superving trees, see [superving-trees]]
  • [breaking] the outbound field in rotor::supervisor_t was renamed just to queue
  • [breaking] rotor::address_t now contains const void* locality
  • [breaking] rotor::asio::supervisor_config_t now contains
    std::shared_ptr to strand, instead of creating private strand
    for each supervisor
  • [bugfix] redundant do_start() method in rotor::supervisor_t was
    ✂ removed, since supervisor now is able to start self after compliting
    🎉 initialization.
  • [bugfix] rotor::supervisor_t sends initialize_actor_t to self
    to advance own state to INITIALIZED via common actor mechanism,
    instead of changeing state directly on early initialization phase
    (do_initialize)
  • 🛠 [bugfix] rotor::asio::forwarder_t now more correctly dispatches
    boost::asio events to actor methods
  • [bugfix] rotor::ev::supervisor_ev_t properly handles refcounter
