fatal error: concurrent map read and map write #940

Closed altergui closed 1 year ago

altergui commented 1 year ago

Disclaimer: i came across this while testing #925, so not on master. so there's a chance that it's a bug of that particular PR, but i want to copypaste the full stack trace here, just in case it's an actual bug from master that only happens very rarely

// LRU implements a non-thread safe fixed size LRU cache

:facepalm:

altergui commented 1 year ago

https://pkg.go.dev/github.com/hashicorp/golang-lru/v2

All caches in this package take locks while operating, and are therefore thread-safe for consumers.

but that refers to caches (ARCCache, Cache or TwoQueueCache) not to the LRU
