[ https://jira.jboss.org/jira/browse/JGRP-940?page=com.atlassian.jira.plugi... ] Bela Ban updated JGRP-940: -------------------------- Summary: MERGE: issue with overlapping merges (NAKACK / UNICAST) (was: MERGE: issue with merging) Description: Merge issue (see attached logs). When we have {A,B,C} on (A, B and C) and {A,B,C,D} (on D) merging, the NAKACK information for C might be incorrect due to the fact that D returned a digest containing old information on C. The issue for UNICAST is similar: D's UNICAST connection table was *not* cleared for A, B or C because it never received a view change. However, A, B and C cleared their UNICAST connection table of D because they excluded D. After a merge, D's unicasts to the other partition (and vice versa) will likely fail because D's UNICAST connection tables for A, B and C still contains the old sequence numbers, but the ones for A, B and C start with #1 again ! A possible solution for NAKACK is to verify we handle digests for overlapping partitions OK, and for UNICAST, we'll might have to introduce a seqno agreement protocol, ie. tagging the first seqno as first=true. A more detailed description will follow. was: Merge issue (see attached logs). When we have {A,B} and {C,D}, A ignores its own portion of the digest {A,B,C,D} on a merge, and installs B, C and D. However, maybe it should ignore the digest information for *all* members it knows about, in this case B as well.
