v1.0.1 - Module Path Fix & Performance Improvements

Patch release addressing package installability, code formatting, and memory optimization.

Changes

• Module Path: Updated go.mod path to github.com/boldbug1/tiny-redis to allow installation via go install.
• Routing: Refactored command dispatch from nested if/else checks to an idiomatic Go switch.
• Memory Optimization: Swapped fmt.Sprintf with fmt.Appendf across response handlers to eliminate intermediate heap allocations.
• Code Standards: Applied canonical formatting via gofmt.

Full Changelog: v1.0.0...v1.0.1

v1.0.0 - Core Engine, AOF Persistence & Graceful Shutdown

Initial release of tiny-redis, a lightweight in-memory key-value database written in Go implementing core Redis internals and protocol serialization.

Features

• Network & Concurrency: Multi-client TCP server utilizing a goroutine-per-connection model with thread-safe data access via sync.RWMutex.
• Wire Protocol: Handcrafted Redis Serialization Protocol (RESP) deserializer reading binary-safe bulk string arrays directly from buffered network streams (bufio.Reader).
• Storage & Operations: In-memory storage supporting PING, ECHO, SET, GET, DEL, EXPIRE, and TTL.
• Two-Tier Eviction:
  • Passive: On-access validation during reads to evict stale entries immediately.
  • Active: Probabilistic background sweeper running on a 100ms ticker with an adaptive 25ms execution cap.
• AOF Persistence: Mutating operations are logged to appendonly.aof using raw RESP format and deterministically replayed on server startup.
• Graceful Shutdown: Traps SIGINT/SIGTERM via channels to cleanly exit the connection accept loop, flush unwritten kernel page buffers to disk via fsync, and close file descriptors.
