----------------------------------------
Summary: FileCache getIfPresent doesn't update cache hit/miss
counters
Key: OAK-6413
URL: https://issues.apache.org/jira/browse/OAK-6413
Project: Jackrabbit Oak
Issue Type: Bug
Components: blob
Affects Versions: 1.6.1
Reporter: Ioan-Cristian Linte
Priority: Minor
{{FileCache.getIfPresent}} bypasses cache access if key is not in cache and
CacheStats for "DataStore-DownloadCache" MBean will always have 100% hit rate
even when Blobs will be downloaded from the BlobStore backend by
{{AbstractSharedCachingDataStore}} because of the miss in the cache.
I suggest the following change:
{{FileCache.getIfPresent}} to call {{CacheLIRS.getIfPresent}} which will update
the cache stats (miss and hit counters).
