Documentation

Overview

Package memorylocker provides an in-memory locking mechanism.

When multiple processes are attempting to access an upload, whether it be by reading or writing, a synchronization mechanism is required to prevent data corruption, especially to ensure correct offset values and the proper order of chunks inside a single upload.

MemoryLocker persists locks using memory and therefore allowing a simple and cheap mechanism. Locks will only exist as long as this object is kept in reference and will be erased if the program exits.
