fetlife/rollout

This system is a feature flag library that manages the activation and rollout of features for specific users, groups, or percentages. It provides a core API for state management and history tracking, backed by pluggable persistence adapters for Redis and Active Record. The architecture separates the core logic from storage implementations, allowing users to choose their preferred backend while maintaining consistent feature lifecycle operations.

The \rollout-redis-adapter\ gem is now available as a standalone package, providing a \Rollout::Adapters::Redis\ backend that stores feature states and history in Redis. This adapter supports full feature lifecycle management (create, read, update, delete), preserves history timestamps using Redis sorted sets, and includes utilities for exporting feature states and history. Users can now integrate the Rollout library with Redis by requiring the new gem entry point.

A new \rollout-active\_record-adapter\ gem is available, allowing feature flag state and history to be stored in application database tables (PostgreSQL, MySQL, SQLite) instead of Redis. This adapter supports Rails generators for migrations, standalone Active Record setups, and an optional in-process feature-state cache (disabled by default). It also includes a migration tool to copy existing feature data from a Redis adapter to the new database tables.

_rollout-active\record-adapter · high confidence

Introduces a new \rollout-active\_record-adapter\ gem that allows storing feature flag states and event history in a relational database via Active Record. This includes a Rails generator to create the necessary \rollout\_features\ and \rollout\_events\ tables, a schema definition with MySQL-specific optimizations (utf8mb4 collation, mediumtext limits), and an adapter implementation that supports an optional in-process feature-state cache with configurable TTL and max size. The adapter also provides a migration tool to import feature data from other sources with verification.

The project now explicitly targets Ruby 2.3.0 via a new .ruby-version file and configures Travis CI to test against Ruby versions 2.0 through 2.6 using both Redis 3 and Redis 4 gemfiles. The build system has been refactored from Jeweler to standard RSpec rake tasks, adding specific tasks for running tests in the Redis and Active Record adapter subdirectories. Documentation has been converted from RDoc to Markdown, and the copyright holder has been updated to BitLove, Inc.

The core Rollout API has been restructured to provide distinct methods for managing feature states, replacing the previous overloaded activate/deactivate calls with specific operations. Users can now explicitly activate or deactivate features, groups, and individual users via new methods such as activate\_group, deactivate\_group, activate\_user, deactivate\_user, and activate\_users. The API also introduces bulk user management with set\_users, percentage-based rollout control via activate\_percentage and deactivate\_percentage, and the ability to attach arbitrary metadata to features using set\_feature\_data and clear\_feature\_data. Additionally, the class now supports querying the state of multiple features at once through multi\_get, feature\_states, and active\_features, and provides a clear! method to reset all feature data.

This release updates the library to version 3.1.0 and introduces a new \FeatureState\ class that serves as the canonical persistence boundary for feature metadata, ensuring data is canonicalized through JSON. The \Feature\ class is now isolated in its own file and uses \FeatureState\ to manage state, improving ergonomics and isolation. Additionally, an optional logging system is added, allowing users to track feature changes with context support, history truncation, and the ability to temporarily disable logging per thread.

Added backend contract and history integration tests; Added comprehensive test suite for Rollout feature management and metadata handling; Added test coverage for Rollout feature state, logging, and backend contracts; Added test suite for the new ActiveRecord adapter gem.

The project has been restructured to split the feature-flip functionality into three distinct gems: the core \rollout\ gem, \rollout-redis-adapter\ (version 0.3.0), and \rollout-active\_record-adapter\ (version 0.1.0). This separation allows users to install only the persistence backend they need, reducing dependencies for those not using Redis or Active Record. The core \rollout\ gem now depends on the \observer\ library and specifies a Ruby version requirement of \>= 2.3, while the adapter gems define their own specific version constraints for Redis (\>= 4.0, \< 7) and Active Record (\>= 7.1, \< 9).
