inaka/worker_pool

This system is an Erlang library named \worker\_pool\ that provides a robust implementation for managing concurrent worker processes. It offers configurable strategies for worker selection, request queuing, and lifecycle supervision, along with event-based monitoring and overrun detection. The project includes a comprehensive test suite to verify pool behavior, worker selection algorithms, and error isolation.

This change introduces the \worker\_pool\ application, providing a robust Erlang worker pool implementation. It includes the main \wpool\ interface for managing pools, a \wpool\_pool\ supervisor for worker lifecycle management, and a \wpool\_queue\_manager\ for handling request queuing and worker availability. The library supports configurable worker strategies (such as best, random, round-robin, and available), overrun detection with customizable handlers, and an event-based callback system for monitoring worker events like creation and death. It also provides a default \wpool\_worker\ implementation for simple RPC-style tasks and exposes statistics and worker retrieval APIs.

src · high confidence

The project has been modernized by switching to rebar3 as the build system, setting the minimum supported OTP version to 27, and adding a suite of development tools including erlfmt for code formatting, hank for shell script linting, and dialyzer for static analysis. The README has been updated to reflect these changes and the new installation instructions.

(repo-wide) · high confidence

Added a comprehensive Common Test suite and supporting test helpers to verify wpool functionality. The new test files include \wpool\_SUITE.erl\ for testing pool lifecycle, shutdown strategies, overrun handling, broadcasting, and supervisor pools; \wpool\_pool\_SUITE.erl\ for worker selection strategies (available, next, random, etc.), queue types, and queue manager options; \wpool\_process\_SUITE.erl\ for gen\_server behavior within workers (init, cast, call, continue, format\_status); and \wpool\_process\_callbacks\_SUITE.erl\ for callback module lifecycle and error isolation. Supporting test doubles (\crashy\_server\, \echo\_server\, \sleepy\_server\, \echo\_supervisor\) and utility functions (\wpool\_test\_utils\, \wpool\_bench\) were also added to facilitate these tests.
