schema: guard schemaCache map with mutex to fix data race - #11
Merged
Conversation
Load writes the package-level schemaCache map while Validate reads it via schemaForType. If Load runs concurrently with request validation (or is called twice concurrently), this is a concurrent map read/write race. Guard access with a sync.RWMutex so writes in Load and reads in schemaForType are properly serialized.
