Changelog

master

• Removes coalesce_requests from the connection::config, this became a request property now, see request::config::coalesce.

• Removes max_read_size from the connection::config. The maximum read size can be specified now as a parameter of the aedis::adapt() function.

• Removes aedis::sync class, see intro_sync.cpp for how to perform synchronous and thread safe calls. This is possible in Boost. 1.80 only as it requires boost::asio::deferred.

• Moves from boost::optional to std::optional. This is part of moving to C++17.

• Changes the behaviour of the second connection::async_run overload so that it always return an error when the connection is lost.

• Adds TLS support, see intro_tls.cpp for how to use it.

• Adds an example that shows how to resolve addresses over sentinels, see subscriber_sentinel.cpp.

• Adds a connection::config::resp3_handshake_timeout. This is timeout used to send the HELLO command.

• Adds endpoint where in addition to host and port, users can optionally provide username, password and the expected server role (see error::unexpected_server_role).

• connection::async_run checks whether the server role received in the hello command is equal to the expected server role specified in aedis::endpoint. To skip this check let the role variable empty.

• Removes reconnect functionanlity from aedis::connection. It is possible in simple reconnection strategies but bloats the class in more complex scenarios, for example, with sentinel, authentication and TLS. This is trivial to implement in a separate coroutine. As a result the enum event and async_receive_event have been removed from the class too.

• Fixes a bug in connection::async_receive_push that prevented passing any response adapter other that adapt(std::vector<node>).

• Changes the behaviour of aedis::adapt() that caused RESP3 errors to be ignored. One consequence of it is that connection::async_run would not exit with failure in servers that required authentication.

• Changes the behaviour of connection::async_run that would cause it to complete with success when an error in the connection::async_exec occurred.

• Ports the buildsystem from autotools to CMake.

v1.0.0

• Adds experimental cmake support for windows users.

• Adds new class aedis::sync that wraps an aedis::connection in a thread-safe and synchronous API. All free functions from the sync.hpp are now member functions of aedis::sync.

• Split aedis::connection::async_receive_event in two functions, one to receive events and another for server side pushes, see aedis::connection::async_receive_push.

• Removes collision between aedis::adapter::adapt and aedis::adapt.

• Adds connection::operation enum to replace cancel_* member functions with a single cancel function that gets the operations that should be cancelled as argument.

• Bugfix: a bug on reconnect from a state where the connection object had unsent commands. It could cause async_exec to never complete under certain conditions.

• Bugfix: Documentation of adapt() functions were missing from Doxygen.

v0.3.0

• Adds experimental::exec and receive_event functions to offer a thread safe and synchronous way of executing requests across threads. See intro_sync.cpp and subscriber_sync.cpp for examples.

• connection::async_read_push was renamed to async_receive_event.

• connection::async_receive_event is now being used to communicate internal events to the user, such as resolve, connect, push etc. For examples see subscriber.cpp and connection::event.

• The aedis directory has been moved to include to look more similar to Boost libraries. Users should now replace -I/aedis-path with -I/aedis-path/include in the compiler flags.

• The AUTH and HELLO commands are now sent automatically. This change was necessary to implement reconnection. The username and password used in AUTH should be provided by the user on connection::config.

• Adds support for reconnection. See connection::enable_reconnect.

• Fixes a bug in the connection::async_run(host, port) overload that was causing crashes on reconnection.

• Fixes the executor usage in the connection class. Before theses changes it was imposing any_io_executor on users.

• connection::async_receiver_event is not cancelled anymore when connection::async_run exits. This change makes user code simpler.

• connection::async_exec with host and port overload has been removed. Use the other connection::async_run overload.

• The host and port parameters from connection::async_run have been move to connection::config to better support authentication and failover.

• Many simplifications in the chat_room example.

• Fixes build in clang the compilers and makes some improvements in the documentation.

v0.2.1

• Fixes a bug that happens on very high load.

v0.2.0

• Major rewrite of the high-level API. There is no more need to use the low-level API anymore.
• No more callbacks: Sending requests follows the ASIO asynchronous model.
• Support for reconnection: Pending requests are not canceled when a connection is lost and are re-sent when a new one is established.
• The library is not sending HELLO-3 on user behalf anymore. This is important to support AUTH properly.

v0.1.2

• Adds reconnect coroutine in the echo_server example.
• Corrects client::async_wait_for_data with make_parallel_group to launch operation.
• Improvements in the documentation.
• Avoids dynamic memory allocation in the client class after reconnection.

v0.1.1

• Improves the documentation and adds some features to the high-level client.

v0.1.0

• Improvements in the design and documentation.

v0.0.1

• First release to collect design feedback.
