* chore: use my referral link of DO * docs: correct WithNonblocking comment about its returned error (#390) * fix: make Reboot() wait for pool to fully release before resetting state (#395) * fix: resolve data race on poolCommon.once field using atomic.Pointer The data race occurred between Reboot() writing p.once = &sync.Once{} and worker goroutines reading p.once.Do(...) concurrently. Fix: change the once field from *sync.Once to atomic.Pointer[sync.Once] so all reads (Load) and writes (Store) are atomic.

Fix: Reboot() now waits on the allDone channel (which is closed when the last worker exits) before resetting pool state. This ensures no worker goroutine is running when the fields are reassigned, eliminating the data race without needing atomic wrappers. Reverts the atomic.Pointer[sync.Once] approach in favor of this fundamental fix.

This prevents a logic race where the old goroutine could set purgeDone/ticktockDone=1 after Reboot() resets them to 0.

By using atomic.Pointer[sync.Once], all reads (Load) and writes (Store) to the once field are properly synchronized.

The real issue is that Reboot() proceeded after allDone (running count hit 0) while worker goroutines were still executing deferred cleanup code. Add workerWg sync.WaitGroup to poolCommon. Each worker goroutine calls wg.Add(1) before spawning and defer wg.Done() as the outermost defer (runs last). Reboot() calls workerWg.Wait() after <-allDone to block until every goroutine has fully exited before resetting pool state.

If workers are still running, the last one to exit closes allDone in its defer as before. This eliminates the race between Reboot() and running workers on once.Do, and removes the unnecessary workerWg complexity.

What
Refactored variable names in
binarySearchfor better readability, while keeping the original logic unchanged.Why
Original variable names like
nlenandbaselare less clear. Renaming them tonandbasemakes the binary search logic easier to follow, without changing any behavior.Changes
worker_loop_queue.gobinarySearchand kept all comments intact.Risk
Zero risk, no logic change.
