- Introduced coalescing logic in `coalescing.go` to handle concurrent identical upstream fetches, including a state machine and response buffering for improved performance.
- Implemented a new cache file format in `format.go`, supporting serialization and deserialization of HTTP responses, along with range request handling.
- Developed an HTTP handler in `handler.go` to manage requests, including special endpoint handling and metrics reporting.
- Added rate limiting functionality in `ratelimit.go` to control per-client and global request rates, enhancing security and performance.
- Created service management capabilities in `service.go` to define and manage cacheable services, including user-agent detection.
- Updated tests in `steamcache_test.go` to cover new functionalities, ensuring robustness and reliability across the codebase.
- Updated `disk.New` to support asynchronous initialization for large caches, improving responsiveness during startup.
- Introduced an eviction function parameter to `disk.New`, ensuring proper handling of over-capacity scenarios.
- Enhanced error handling in various components, including memory and disk tests, to ensure robustness and clarity.
- Refactored tests to validate new behaviors, including checks for delayed attachment and proper error propagation.
- Removed obsolete error handling code and tests related to the now-deleted errors package, streamlining the codebase.
- Updated the 'bench' target in the Makefile to run all benchmarks for MemoryFS and DiskFS, improving clarity and coverage.
- Added explicit post-eviction consistency checks in DiskFS tests to ensure on-disk files are removed after eviction.
- Introduced new benchmarks for memory eviction strategies under pressure, enhancing test coverage for memory management.
- Improved error handling in benchmark tests for both disk and memory file systems, ensuring robustness during performance evaluations.
- Refactored key generation in tests for consistency and clarity.
- Introduced a YAML-based configuration system, allowing for automatic generation of a default `config.yaml` file.
- Updated the application to load configuration settings from the YAML file, improving flexibility and ease of use.
- Added a Makefile to streamline development tasks, including running the application, testing, and managing dependencies.
- Enhanced `.gitignore` to include build artifacts and configuration files.
- Removed unused Prometheus metrics and related code to simplify the codebase.
- Updated dependencies in `go.mod` and `go.sum` for improved functionality and performance.
- Updated disk_test.go to replace Set and Get with Create and Open methods for better clarity and functionality.
- Modified fileinfo.go to include package comment.
- Refactored gc.go to streamline garbage collection handling and removed unused statistics.
- Updated gc_test.go to comment out large random tests for future implementation.
- Enhanced memory.go to implement LRU caching and metrics for memory usage.
- Updated memory_test.go to replace Set and Get with Create and Open methods.
- Removed sync.go as it was redundant and not utilized.
- Updated vfs.go to reflect changes in the VFS interface, replacing Set and Get with Create and Open.
- Added package comments to vfserror.go for consistency.
