v0.5.1

Bug Fixes

• Fix data race in OnTrafficFromServer — The same v1.Struct pointer was sent to UpdateCacheChannel and returned to GatewayD via gRPC. The UpdateCache goroutine mutated Fields while gRPC serialized them concurrently, corrupting responses under load. Fixed by cloning the struct with proto.Clone before sending to the channel.
• Fix lint issues — Added checked type assertion for proto.Clone result and widened depguard allow list to permit google.golang.org/protobuf.

v0.5.0

What's Changed

Bug Fixes

• Fix goroutine death in UpdateCache — return statements on error paths permanently killed the cache update goroutine after a single transient error (e.g. empty database name). Changed to continue so caching survives errors. Resolves #64.
• Fix IsCacheNeeded checking cache key instead of query — Date/time function detection was applied to the raw cache key (binary bytes) instead of the parsed SQL query string, making it unreliable.
• Fix ExitOnStartupError read before set — The flag was checked before its value was loaded from config, so the first startup error check always evaluated to false.
• Fix close(nil) channel panic — Closing the UpdateCacheChannel when config was nil caused a runtime panic.
• Fix double-counting cache misses — CacheMissesCounter was incremented twice on a single cache miss in OnTrafficFromClient.

Improvements

• New CacheErrorsCounter metric — Separates Redis operation errors from genuine cache misses. Previously both were conflated under CacheMissesCounter.
• Config validation with defaults — redisURL, expiry, and scanCount are now validated with warnings and sensible defaults instead of silently accepting zero-values.
• Graceful goroutine shutdown — Added WaitGroup to ensure the UpdateCache goroutine drains pending updates before process exit.
• Deduplicated startup error handling — Extracted repeated ExitOnStartupError + close + exit pattern into a handleStartupError helper.
• Reduced nestif complexity — Inverted caching precondition in UpdateCache to use early continue.
• Fixed typos — cachedRespnseKey → cachedResponseKey, DateFucntion → DateFunction.
