sasa1977/con_cache

ConCache is an in-memory caching library for Elixir that provides concurrent access to ETS-based data stores. It manages cache instances and their associated lock processes to ensure reliable, non-blocking operations. The system focuses on modernizing the internal architecture by replacing legacy lock modules with dedicated GenServers and supervisors, while maintaining comprehensive test coverage for all cache operations.

The project now specifies Erlang/OTP 26.2 and Elixir 1.16 in .tool-versions, updating the development environment to the latest supported versions. Additionally, a .formatter.exs file has been added to configure the Mix formatter, standardizing code formatting for the project.

The lock subsystem now uses new internal data structures: ConCache.Lock.Monitors tracks process references and lock instances using Maps and MapSets, while ConCache.Lock.Resource manages lock state, ownership, and pending queues. This refactors the underlying implementation to use modern Elixir collections (Map/MapSet) instead of older HashDict/HashSet, improving consistency and performance.

_lib/con\cache/lock · high confidence

The cache implementation has been refactored to use Elixir structs instead of records, including a new \ConCache.Item\ struct for storing values and TTLs. The legacy \BalancedLock\, \KeyBalancer\, \Lock\, and \TtlManager\ modules have been removed, simplifying the internal architecture and aligning with modern Elixir conventions.

lib · high confidence

The internal architecture of ConCache has been restructured to improve concurrency and reliability. The library now uses a dedicated GenServer for lock management (lib/con\_cache/lock.ex) and a separate supervisor for lock processes (lib/con\_cache/lock\_supervisor.ex), which helps avoid mutual blocking of caches. The owner process (lib/con\_cache/owner.ex) has been converted to a plain GenServer and is now started under a separate supervisor, ensuring that all cache processes terminate correctly upon registry termination. Additionally, the application entry point (lib/con\_cache/application.ex) now starts a Registry to manage cache instances, replacing the previous custom registry implementation.

_lib/con\cache · high confidence

Added comprehensive tests for ConCache operations including put, insert\_new, delete, update, update\_existing, and get\_or\_store, with specific coverage for bag and duplicate\_bag ETS options. Added tests for TTL validation errors and child\_spec generation. Updated lock tests to use ConCache.Lock namespace and added monitoring/timeout tests for the lock mechanism. Refactored test helper to use ExUnit.start() with parentheses.

test · high confidence

The project now requires Elixir 1.7 or higher, reflecting a significant jump from earlier versions (previously 1.4/1.5/1.6). The \mix.exs\ file has been updated to include a \package\ section with metadata (description, maintainers, licenses, links) and a \docs\ configuration for \ex\_doc\. Dependencies have been modernized: \exactor\ has been removed entirely, while \dialyxir\ and \ex\_doc\ are now specified with version constraints for development. A new runtime dependency on \:telemetry\ has been added, and the application configuration now explicitly lists \:logger\ and \:telemetry\ as extra applications, with a dedicated application module \ConCache.Application\ defined.
