locks

Documentation

Overview

Package locks provides a process-global keyed mutex used to serialize mutating filesystem operations on a single pack's cache directory.

The lock must live at package scope: the runner factory and resolver are constructed fresh per HTTP request and per detonation, so an instance-scoped lock would not be observed across those independent instances.

Functions

func Acquire

func Acquire(key string) (release func())

Acquire locks the mutex associated with key and returns a release closure that unlocks it. Calls with the same key are serialized; calls with different keys proceed concurrently.
