[infinispan-issues] [JBoss JIRA] (ISPN-9028) Write-only segments should be invalidated during the READ_NEW phase

Write-only segments should be invalidated during the READ_NEW phase ------------------------------------------------------------------- Key: ISPN-9028 URL: https://issues.jboss.org/browse/ISPN-9028 Project: Infinispan Issue Type: Bug Components: Core Affects Versions: 9.2.1.Final Reporter: Dan Berindei Assignee: Dan Berindei Labels: testsuite_stability Fix For: 9.3.0.Alpha1 When a rebalance removes a segment X from node A, node A keeps updating entries in segment X until the rebalance finishes, and only deletes the entries of segment X after entering the NO_REBALANCE phase. This is problematic for tests that work with the data container directly, because {{waitForNoRebalance()}} doesn't wait for the removal of stale entries. The test will work without an explicit wait most of the time, so this is a recipe for random test failures (e.g. ISPN-8728). As described in ISPN-5021, we can prevent any writes to segment X at the start of the READ_NEW_WRITE_ALL phase, send the phase confirmation to the coordinator, and then remove the entries asynchronously. We just need to keep track of the removal task and only install/confirm the NO_REBALANCE phase once all the entries that we don't own have been removed.
