FiberedMysql2

FiberedMysql2 adds Fiber support to ActiveRecord::ConnectionAdapters::Mysql2Adapter for Rails 6. This is a stop-gap until Rails 7, which adds isolation_level: :fiber to ActiveRecord.

Add this line to your application's Gemfile:

gem 'fibered_mysql2'

And then execute:

$ bundle

Or install it yourself as:

$ gem install fibered_mysql2

Tested with Rails 6.0, Ruby 3, and Async.

Behaves the same as ActiveRecord::ConnectionAdapters::Mysql2Adapter but with using Fibers rather than Threads for tracking ownership when leasing/expiring connections.

connection = FiberedMysql2::FiberedMysql2Adapter.new(client, logger, options, config)
connection.lease
connection.expire

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
