[improvement, breaking] output directories are set to bin for cmake
[improvement, breaking] actor_base_t::make_error() is marked as const

[bugfix] fix segfault in delivery plugin in debugging mode
(try to set env ROTOR_INSPECT_DELIVERY=99 to see)
0.28 (22-Jan-2024)
[cmake, bugfix] add missing header into installation
0.27 (21-Jan-2024)
[feature] new interface message_visitor_t
[feature] new interface message_stringifier_t and the default implementation
default_stringifier_t which allows to dump messages. It is not a production but
a diagnostic/debug tool, due to performance restrictions.
[feature] system_context_t provides a reference to default message_stringifier_t;
it is possible to have a custom one
[feature, breaking] extended_error_t holds a reference to a request message,
which caused an error
[examples, tests, win32] fix ev examples and tests
[example] modernize examples/thread/sha512.cpp to use recent openssl version
[breaking] cmake requirements are lowered to 3.15
[breaking] fix minor compilation warnings
0.26 (08-Jan-2024)
[feature] start_timer callback not only method, but any invocable
[feature, conan] enable_ev option which add libev
[breaking, conan] boost minimum version 1.83.0
[testing, conan] remove catch2 from sources and make it dependencies
[bugfix] requests do not outlive actors (i.e. they are cancelled on shutdown_finish)
[example] there is my another open-source project syncspirit,
which uses rotor under hood. I recommend to look at it, if the shipped examples are too-trivial, and
don't give you an architectural insight of using rotor.
0.21 (25-Mar-2022)
[improvement] preliminary support of conan package manager
[bugfix] fix compilation warnings on Windows/MSVC
[bugfix] add missing header for rotor::thread installation
0.20 (20-Feb-2022)
[improvement] superviser can create spawner, which has a policy to auto-spawns
new actor instance if previous instance has been shutdown. This is similar to
escalate_failure supervising in erlang,
see dedicated article
[improvement] actor can now autoshutdown_supervisor(), when it shutdown
[improvement] actor can now escalate_failure(), i.e. trigger shutdown own supervisor
when it finished with failure
[improvement] messages delivery order is persevered per-locality (see issue #41)
[example] examples/thread/ping-pong-spawner (new)
[example] examples/autoshutdown (new)
[example] examples/escalate-failure (new)
[documentation] updated Design principles
[documentation] updated Examples
[documentation] updated Introduction
0.19 (31-Dec-2021)
[improvement] performance improvement in inter-thread (+20%) and cross-thread messaging
[bugfix] supervisor does not shut self down in rare conditions, when it fails to initialize self
[bugfix] link_server plugin should ignore unlink_notifications
[bugfix] avoid cycle (i.e. memleak) in rare cases when supervisor is shutdown, but an external
message arrives for processing
0.18 (03-Dec-2021)
[improvement] add static_assert for noexcept check of a hanler signature
[improvement/breaking] instead of using std::error_code the extended_error class
is used. It wraps std::error_code, provides string context and pointer to the next
extended_error cause. This greatly simplifies error tracking of errors. Every response
now contains ee field instead of ec.
[improvement] actor has shutdown reason (in form of extended_error pointer)
[improvement] delivery plugin in debug mode it dumps shutdown reason in shutdown trigger
messages
[improvement] actor identity has on_unlink method to get it know, when it has been
unlinked from server actor
[improvement] add resources plugin for supervisor
[breaking] all responses now have extended_error pointer instead of std::error_code
[breaking] shutdown_request_t and shutdown_trigger_t messages how have
shutdown reason (in form of extended_error pointer)
[bugfix] link_client_plugin_t do not invoke custom callback, before erasing request
in case of failure
[bugfix] child_manager_plugin_t reactivate self if a child was created from other
plugin.
[bugfix] registry actor incorrectly resolves postponed requests to wrong addresses
0.13 (26-Dec-2020)
[improvement] delivery plugin in debug mode dumps discarded messages
[breaking] state_response_t has been removed
[bugfix] allow to acquire & release resources in via resources_plugin_t, during
other plugin configuration
[bugfix] foreigners_support_plugin_t did not deactivated self properly, caused
assertion fail on supervisor shutdown, when there was foreign subscriptions
[bugfix] link_client_plugin_t did not notified linked server-actors, if its actor is
going to shutdown; now server-actors are requested to unlink
[bugfix] starter_plugin_t sometimes crashed when subscription confirmation message
arrives when actor is in non-initializing phase (i.e. shutting down)
[bugfix] root supervisor is not shutdown properly when it is linked as "server"
[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 accessible via pointer instead of
reference
[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
0.08 (12-Apr-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
0.07 (02-Apr-2020)
[improvement] more modern cmake usage
0.06 (09-Nov-2019)
[improvement] registry actor was added to allow via name/address runtime
matching do services discovery
[improvement, breaking] minor changes in supervisor behavior: now it
is considered initialized 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
0.05 (22-Sep-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
0.04 (14-Sep-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 subscribers 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.
0.03 (25-Aug-2019)
[improvement] locality notion was introduced, which led to possibility
to build supervising trees, see [blog-cpp-supervisors]
[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 completing
initialization.
[bugfix] rotor::supervisor_t sends initialize_actor_t to self
to advance own state to INITIALIZED via common actor mechanism,
instead of changing state directly on early initialization phase
(do_initialize)
[bugfix] rotor::asio::forwarder_t now more correctly dispatches
boost::asio events to actor methods
