Changes for version 0.60 - 2026-02-24

  • ENHANCEMENTS
    • Added debugobj() and debugfh() methods to DBIx::Class::Async::Storage::DBI for full API compatibility with DBIx::Class::Storage::DBI. These methods enable SQL debugging and logging with custom debug objects or filehandles.
    • Enhanced worker processes to respect debug flag from parent process. When storage->debug(1) is called, SQL statements are now logged to STDERR in worker processes, enabling comprehensive query debugging in async mode.
    • Improved SQL generation consistency in DBIx::Class::Async::ResultSet. Column ordering and attribute merging are now fully deterministic across multiple invocations of the same query, improving query cache effectiveness and debugging reliability.
    • Added attribute deduplication in ResultSet->search() chaining. Accumulating attributes (join, prefetch, columns, select, as, order_by, group_by, having) are now automatically deduplicated using stable serialization, preventing duplicate JOINs and maintaining consistent SQL structure.
  • TESTS
    • Added t/152-sql-consistency.t to verify deterministic SQL generation across multiple query invocations, including tests for column order stability, attribute merging, and deduplication behaviour.
    • Added t/spelling.t to perform British spell check for AUTHOR_TESTING.
  • DOCUMENTATION
    • Added comprehensive DEBUGGING section to DBIx::Class::Async::Storage::DBI documenting debug(), debugobj(), and debugfh() methods with usage examples.
    • Enhanced debug() method documentation to clarify integration with debugobj and worker process behavior.
    • Added detailed POD for SQL generation consistency guarantees and their benefits for query caching, performance analysis, and testing.
  • INTERNAL
    • Refactored _merge_attrs() in ResultSet.pm with clearer logic and improved deduplication using Data::Dumper for nested structure comparison.
    • Extracted _merge_cond(), _is_empty_cond(), and _dedup_key() helper methods for better code organization and reusability.
    • Modified _call_worker() in Async.pm to pass debug flag to worker processes, enabling consistent debug behavior across process boundaries.
