[ https://issues.jboss.org/browse/ISPN-8168?page=com.atlassian.jira.plugin.... ] Gustavo Fernandes commented on ISPN-8168: ----------------------------------------- The cache {{LuceneIndexesMetadata}} has an entry with a value of type {{FileListCacheValue}} that store a list of Strings, which is {{DeltaAware}}. So a command to replace an item from a value replicates only the removed item. In the TRACE below, the value "_4.nvd" is supposed to be removed from the list, but the whole list is wiped: The delta aware becomes a FunctionalCommand {code} 09:29:22,672 TRACE (jgroups-6,ISPN,gfernandes-29609:[]) [StateTransferInterceptor] Retrying command ReadWriteKeyValueCommand {key=*|emails|-1, value=*FileListCacheValueDelta{ops=[DeleteOperation{element='_4.nvd'}]}*, prevValue=null, prevMetadata=null, flags=[SKIP_INDEXING, IGNORE_RETURN_VALUES, COMMAND_RETRY], valueMatcher=MATCH_ALWAYS, successful=true} for topology 11 {code} Topology is changed in every step of the test, so a retry happens: {code} 09:29:22,673 TRACE (jgroups-6,ISPN,gfernandes-29609:[]) [EntryWrappingInterceptor] This is a retry- removing looked up entry ReadCommittedEntry(392a2ecf){key=*|emails|-1, value=FileListCacheValue [filenames=[_3.si, _0.si, _1.cfe, _1.si, _2.si, _0.cfs, _2.cfs, _4.cfe, _3.cfe, segments_6, segments_5, _4.fdx, _4_Lucene50_0.doc, _4_Lucene50_0.tim, _1.cfs, _0.cfe, _2.cfe, _3.cfs, _4.cfs, _4.si]], isCreated=false, isChanged=false, isRemoved=false, isValid=true, isExpired=false, skipLookup=false, metadata=MetaParamsInternalMetadata{params=MetaParams{length=0, metas=[]}}} {code} We can see that in the data container the FileListCacheValue contains lots of values: {code} 09:29:22,673 TRACE (jgroups-6,ISPN,gfernandes-29609:[]) [EntryFactoryImpl] Exists in context? null 09:29:22,673 TRACE (jgroups-6,ISPN,gfernandes-29609:[]) [EntryFactoryImpl] Retrieved from container MetadataImmortalCacheEntry{key=*|emails|-1, value=FileListCacheValue [filenames=[_3.si, _0.si, _1.cfe, _1.si, _2.si, _0.cfs, _2.cfs, _4.cfe, _3.cfe, segments_6, segments_5, _4.fdx, _4_Lucene50_0.doc, _4_Lucene50_0.tim, _1.cfs, _0.cfe, _2.cfe, _3.cfs, _4.cfs, _4.si]], metadata=MetaParamsInternalMetadata{params=MetaParams{length=0, metas=[]}}} 09:29:22,673 TRACE (jgroups-6,ISPN,gfernandes-29609:[]) [EntryFactoryImpl] Creating new entry for key *|emails|-1 09:29:22,673 TRACE (jgroups-6,ISPN,gfernandes-29609:[]) [EntryFactoryImpl] Updated context entry null -> ReadCommittedEntry(31f4a69f){key=*|emails|-1, value=FileListCacheValue [filenames=[_3.si, _0.si, _1.cfe, _1.si, _2.si, _0.cfs, _2.cfs, _4.cfe, _3.cfe, segments_6, segments_5, _4.fdx, _4_Lucene50_0.doc, _4_Lucene50_0.tim, _1.cfs, _0.cfe, _2.cfe, _3.cfs, _4.cfs, _4.si]], isCreated=false, isChanged=false, isRemoved=false, isValid=true, isExpired=false, skipLookup=false, metadata=MetaParamsInternalMetadata{params=MetaParams{length=0, metas=[]}}} 09:29:22,673 TRACE (jgroups-6,ISPN,gfernandes-29609:[]) [CallInterceptor] Invoking: ReadWriteKeyValueCommand {code} But those values are wiped when the functional command is executed: {code} 09:29:22,674 TRACE (jgroups-6,ISPN,gfernandes-29609:[]) [ReadWriteKeyValueCommand] Execute read-write function on previous value null and previous metadata null 09:29:22,674 TRACE (jgroups-6,ISPN,gfernandes-29609:[]) [BaseDistributionInterceptor] Current topology 11, command topology 11 09:29:22,674 TRACE (jgroups-6,ISPN,gfernandes-29609:[]) [EntryWrappingInterceptor] About to commit entry ReadCommittedEntry(31f4a69f) {key=*|emails|-1, value=FileListCacheValue [filenames=[]], isCreated=false, isChanged=true, isRemoved=false, isValid=true, isExpired=false, skipLookup=false, metadata=MetaParamsInternalMetadata{params=MetaParams{length=0, metas=[]}}} 09:29:22,674 TRACE (jgroups-6,ISPN,gfernandes-29609:[]) [DefaultDataContainer] Creating new ICE for writing. *Existing=MetadataImmortalCacheEntry{key=*|emails|-1, value=FileListCacheValue [filenames=[_3.si, _0.si, _1.cfe, _1.si, _2.si, _0.cfs, _2.cfs, _4.cfe, _3.cfe, segments_6, segments_5, _4.fdx, _4_Lucene50_0.doc, _4_Lucene50_0.tim, _1.cfs, _0.cfe, _2.cfe, _3.cfs, _4.cfs, _4.si]*], metadata=MetaParamsInternalMetadata{params=MetaParams{length=0, metas=[]}}}, metadata=MetaParamsInternalMetadata{params= MetaParams{length=0, metas=[]}}, new value=FileListCacheValue [filenames=[]] 09:29:22,674 TRACE (jgroups-6,ISPN,gfernandes-29609:[]) [DefaultDataContainer] Store MetadataImmortalCacheEntry {key=*|emails|-1, value=FileListCacheValue [*filenames=[]]*, metadata=MetaParamsInternalMetadata{params=MetaParams{length=0, metas=[]}}} in container {code} -- This message was sent by Atlassian JIRA (v7.2.3#72005)
