Vikas Saurabh updated OAK-3494: ------------------------------- Attachment: OAK-3494.patch Attached [patch|OAK-3494.patch] (which includes the test case patch from above). [~mreutegg], [~egli] can you guys please review? I'm completely unsure if I've used Jsop parsing correctly. > MemoryDiffCache should also check parent paths before falling to Loader (or > returning null) > ------------------------------------------------------------------------------------------- > > Key: OAK-3494 > URL: https://issues.apache.org/jira/browse/OAK-3494 > Project: Jackrabbit Oak > Issue Type: Bug > Components: core > Reporter: Vikas Saurabh > Labels: performance > Attachments: OAK-3494-TestCase.patch, OAK-3494.patch > > > Each entry in {{MemoryDiffCache}} is keyed with {{(path, fromRev, toRev)}} > for the list of modified children at {{path}}. A diff calcualted by > {{DocumentNodeStore.diffImpl}} at '/' (passively via loader) or > {{JournalEntry.applyTo}} (actively) fill each path for which there are > modified children (including the hierarchy) > But, if an observer calls {{compareWithBaseState}} on a unmodified sub-tree, > the observer will still go down to {{diffImpl}} although cached parent entry > can be used to answer the query. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
