[Unreleased]

[4.1.0]

Changed

Remove dependency on mutex_m, instead using Thread::Mutex directly.

[4.0.0]

Changed

Moved select_db inside of the with_raw_connection block of the #raw_execute method. This should allow for using Rails' built-in reconnect & retry logic with the Trilogy adapter or Rails 7.1+.
In Rails 7.1+, when a new ConnectionProxy is instantiated the database switch is lazily triggered by the subsequent database query instead of immediately.

Removed

Calling #clean! and #verified! on connections because it is no longer necessary.

[3.2.0]

Added

Calls #verified! on the connection after #clean!.

[3.1.1]

Fixed

A typo causing #clean! to not run.

[3.1.0]

Added

Calls #clean! on the connection after switching databases.

[3.0.0]

Added

Support and testing for Rails 7.2 & Rails main.

Removed

Support for ActiveRecord's legacy connection handling.

[2.2.0]

Removed

Support for Ruby 3.0.

Added

Rails 6.1 testing with Trilogy.

Fixed

Fixed using ActiveRecordHostPool and the activerecord-trilogy-adapter v3.1+.

Changed

ActiveRecordHostPool will now raise an exception if you try to use a version of activerecord-trilogy-adapter < 3.1.

[2.1.0]

Changed

ActiveRecordHostPool now uses prepend to patch #execute, #raw_execute, #drop_database, #create_database, and #disconnect!. Prepending is incompatible when also using alias or alias_method to patch those methods; avoid aliasing them to prevent an infinite loop.

Removed

Dropped support for Ruby 2.7.x.

[2.0.0]

Added

Add support for Rails 7.1.
Trilogy is now a supported MySQL database adapter. ActiveRecordHostPool no longer requires mysql2, nor does it explicitly require activerecord-trilogy-adapter. Applications using ARHP will now need to explicitly require one of these adapters in its gemfile. When using activerecord-trilogy-adapter also ensure that the trilogy gem is locked to v2.5.0+.

Removed

Remove mysql2 as a direct dependency, test Rails 7.0 with mysql2 and activerecord-trilogy-adapter.
Remove support for Rails 5.1, 5.2, and 6.0.

Fixed

Implement equality for connection proxies to consider database; allows fixture loading for different databases

[1.2.5] - 2023-07-14

Added

Start testing with Ruby 3.2.

Removed

Drop Ruby 2.6.

Fixed

Use a mutex inside PoolProxy#disconnect!. This might fix some ActiveRecord::ConnectionNotEstablished issues when a multi-threaded application is under heavy load. (Only applies when using Rails 6.1 or newer).

[1.2.4] - 2023-03-20

Fixed

Fixed the warning when using ruby2_keywords on execute_with_switching.
Simplified the clear_query_caches_for_current_thread patch.

[1.2.3] - 2023-01-19

Fixed

Fix the patch for ActiveRecord::Base.clear_query_caches_for_current_thread to work correctly right after the creation of a new connection pool. (#105)

[1.2.2] - 2023-01-18

Added

Add a new ActiveRecordHostPool::PoolProxy#_unproxied_connection method which gives access to the underlying, "real", shared connection without going through the connection proxy, which would call #_host_pool_current_database= on the underlying connection. (#104)

Fixed

Fix the patch for ActiveRecord::Base.clear_on_handler to work correctly right after the creation of a new connection pool. (#104)

[1.2.1] - 2022-12-23
