rawdb: Race condition in freezer table #20420

Description

@MariusVanDerWijden

Hi I noticed a race condition between
func (t *freezerTable) Retrieve(item uint64) ([]byte, error) { and
func (t *freezerTable) Close() error {
because retrieve does not lock the rlock at the beginning.
We could use the same methodology as in


However I think since close isn't called often we could just not acquire the second lock as it would impact every retrieve calls performance.
If you guys agree, please put a wontfix label and close the issue!
