None of the > regression tests are really suitable, as they do not impose any big backlogs. This isn't something that is amenable to any of our automated testing; it does not seem appropriate to add any explicit test to the suite. The apropos test is more "observational"; just... - Set up a cluster - Set up a data source that's injecting updates to the origin node - Manually stop and start a slon, having debugging set to a level that shows off the SYNC grouping computation. Stop the slon to let some SYNCs build up, restart to see how it catches up. All worked fine for me. This is apropos as a post-2.1 change; once we open development of 2.1, it should go to Steve/Jan for review. Assigning it to Jan to arrange review. -- Configure bugmail: http://www.slony.info/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
