Here is the v11 patch-set. Changes are:
1) Updated conflict type names in accordance with the recent commit[1] as -
update_differ --> update_origin_differs
delete_differ --> delete_origin_differs
2) patch-001:
- Implemented the RESET command to restore the default resolvers as
suggested in pt.2a & 2b in [2]
3) patch-004:
- Rebased the patch which implements last_update_wins resolver and
clock-skew management.
- Restricts the setting of two_phase and last_update_wins together
- Prevents the start of parallel apply-worker if 'last_update_wins'
is configured for any conflict_type.
- Added test cases for last_update_wins in 034_conflict_resolver.pl
Thanks, Shveta for your help in patch-004 solutions and thank you Ajin
for providing RESET command changes(patch-001).
