mperham/connection_pool

This system is a Ruby library that manages connection pooling for multithreaded and multi-process applications. It provides a robust API for initializing pools with configurable timeouts and sizes, while ensuring resource safety through automatic connection discarding and fork-aware cleanup. The library supports lazy connection creation, graceful shutdowns, and per-invocation timeout overrides to handle concurrent access efficiently.

The connection pool library has been significantly refactored, changing the initialization signature to use keyword arguments (timeout, size, auto\_reload\_after\_fork) and introducing a new Wrapper class accessible via ConnectionPool.wrap. A key behavioral change is the addition of discard\_current\_connection, allowing threads to mark invalid connections for disposal rather than returning them to the pool. The API also now supports per-invocation timeout overrides via the with method and automatically reloads connections after a fork by default.

lib · high confidence

The connection pool library has been updated to version 3.0.2, introducing significant behavioral changes to resource management and process safety. A new \lib/connection\_pool/fork.rb\ module ensures that checked-out connections are properly checked in and closed after a process fork, preventing stale resource usage in multi-process environments. The internal \TimedStack\ implementation has been refactored to support lazy connection creation and includes a new \shutdown\ method for graceful teardown, while the legacy \TimedQueue\ class has been removed in favor of the new stack-based approach. Additionally, a \Wrapper\ class is now available to provide a simplified interface for common pool operations like \with\, \pool\_size\, and \pool\_available\.

_lib/connection\pool · high confidence

Added a new test suite covering the ConnectionPool and TimedStack components, including tests for multithreaded usage, timeout handling, stack operations (push, pop, shutdown, reload), and subclassing overrides. Also added a benchmark script to measure ConnectionPool\#with performance and a test helper to manage instance reset and warning suppression.

test · high confidence

The gem now requires Ruby 3.2.0 or higher, dropping support for older versions. Development dependencies have been added to the gemspec, including bundler, maxitest, minitest-mock, and rake, while the Gemfile has been updated to include standard, benchmark-ips, maxitest, and simplecov for local development and testing.
