4.0.0.

September 20th, 2017

• ZADD score param changed from map to multimap to allow multiple elements with same score
• connection_callback (replacement of disconnection_callback). Called for any steps of connection process (attempt, success, failure, reconnection, drop, ...)

• Sentinel support
• Automatic reconnection if requested
• Connection timeout
• Ability to set number of io workers if you are working with tacopie
• redis_client renamed into client
• redis_subscriber renamed into subscriber
• commands that failed to be sent (client not connected or disconnected) get their callback called with an error reply connection failure. This ensure that now all callbacks are always called
• if reconnection process is enabled and succeed, failed commands are resent
• if you send command and commit while client is not connected, it will now dismiss the commands and call their callback with an error, or resend them if reconnection is enabled. This is a change compared to the existing behavior that simply kept the commands in the buffer.
• doxygen documentation

• future_client: all functions have been merge into the redis_client
• disconnection_callback: it is now replaced by the connection callback

This is a major release with lots of breaking changes. It aims to enable high availability configuration as well as improved consistency with an enhanced design.

If you are upgrading please consider the following breaking changes:

• redis_client is now client and redis_subscriber is now subscriber
• future_client has been removed, but it is actually merged into client. Simply switch from future_client to client and you will have the same behavior
• disconnection_callback has been removed and replaced by a connection_callback. If you are looking for exact same behavior, you will have to check if the state param is equal to dropped.
• commands callbacks are always called. In case of failure, an error reply is passed in.

Any other changes should not be breaking changes but you might be interested into the added features.

None

None

3.5.0.

April 9th, 2017

None

• New feature - Update tacopie ref - Provide support for Unix socket. Simply pass in 0 as the port when building a redis_client, redis_subscriber or future_client. Then, the host will automatically be treated as the path to a Unix socket instead of a real host. - More in #67.

None

3.4.0.

• Change: update tacopie ref - IO Service is now based on select and not on poll anymore to solve some issues encountered on windows due to the buggy implementation of poll on windows Systems.

None

None

3.3.0.

• Rename redis_client::before_callback into redis_client::set_callback_runner which is more relevant.
• Before, future_client automatically called .commit when sending a command, meaning that no pipelining was done for the future_client. This has been changed and the future_client do not call .commit anymore: this is a breaking change and you must call .commit or .sync_commit when you wish the commands to be effectively sent. Please refer to the examples if necessary.

• Add commit and sync_commit methodsto the future_client for pipelining support.
• documentation for redis_client::before_callback has been added
• documentation for future_client has been added

None

3.2.1.

• Fix static initialization order fiasco condition
• Change __CPP_REDIS_USE_TACOPIE (cmake variable: USE_TACOPIE) into __CPP_REDIS_USE_CUSTOM_TCP_CLIENT (cmake variable: USE_CUSTOM_TCP_CLIENT). Of course, the meaning is now the opposite.

None

None

3.2.0.

• tacopie is no longer a mandatory dependency, but just provided by default and can be override if necessary.

• add a new interface, cpp_redis::network::tcp_client_iface that allows you to use your own tcp_client in place of tacopie.

• The sync_client has been removed as it was a duplicate of redis_client::sync_commit but with a different implementation based on futures. Please use redis_client and call sync_commit instead.

3.1.2.

• rename the setbit() function into setbit_() in order to avoid conflict with the standard library macro setbit causing compilation error.

• add send() method to the sync_client and future_client.

None

3.1.1.

• Fix: subscriber callbacks were sometimes not called due to poll not listening to the appropriate events. Mostly impacted windows as referred in #51, but unix version might also be impacted. Fixed by updating the reference tacopie which contains the fix.

None

None

3.1.0.

• Fix: compilation for specific windows compilers concerning atomic variables
• Fix: handle correctly array replies with negative size by returning a null reply instead of throwing an invalid format exception
• Fix: Bump tacopie version to retrieve a fix concerning gethostbyname() thread-safety issue on unix
• Fix: compilation for programs based on Qt ('slots' conflict)

• Add some overloads for the Z set functions to support floating point values
• Add an auth method to the subscriber class to allow a subscriber to authenticate on the redis server

None

3.0.0.

• Rewrite the network side of cpp_redis by using the tacopie library

• Tacopie is now a submodule of cpp_redis

• redis_client and redis_subscriber instances can be assigned specific io_service

• Integration Tests
• Travis Integration
• Wiki
• Port of the library on Windows
• Support for acknowledgement callbacks for cpp_redis::redis_subscriber
• Logging system
• Compilation Customizations
