Redis Tools

Some redis utils depend on https://github.com/go-redis/redis

import (
    gredis "github.com/Laisky/go-redis/v2"
    "github.com/go-redis/redis"
)

func main() {
    rtils := NewRedisUtils(redis.NewClient(&redis.Options{}))
}

• getset.go: common utils of get/set
• sync.go: distributed locks

Keep the acquisition context returned by Lock and pass that exact context to Unlock. A shared object may be used concurrently; logical acquisitions receive different tokens. Recursive calls must use a live returned lock context and balance every successful call. Parent-only release of an active lease fails closed. Upgrade every client sharing a lock name before relying on the repaired protocol. Lease contexts do not replace datastore fencing for noncooperative work.

Prefix lookup treats metacharacters literally and has key, byte, work and time budgets; a limit failure returns no partial map. GetItemWithPrefixLimited permits explicit trusted limits. RPush enforces its maximum atomically and rejects an oversized batch. See security remediation.
