Bill Burcham commented on GEODE-8240:
-------------------------------------
with [~rhoughton]'s help I was able to convince geode-old-versions to vend my
locally-modified old version (based on 1.12.0). Added a README out on my PR
that’ll make it to develop eventually:
https://github.com/apache/geode/blob/540db11040dbf01a84bd4c3f4e891ae3768ac20b/geode-old-versions/README.md
So the fix for the proximate cause of the rolling upgrade bug has gotten some
validation now (the test from [~alberto.gomez]'s PR passes in my development
environment).

> This problem was introduced in 1.12.0 and is present in all lines derived
> from that one, including 9.10, 1.13, and current develop/1.14
> What's actually happening is that the locator _is_ upgraded to a newer
> version. It joins with an older coordinator (that's running e.g. 1.12.0) and
> that coordinator produces a view showing the new locator/member as running
> the same version, in this case 1.12.0, as the coordinator.
> Eventually, all locators will be upgraded. But the view carries the incorrect
> version indication.
> The root cause seems to be that when {{GMSMemberData.setVersionObject(short
> versionOrdinal)}} sees a version ordinal that is unknown, i.e. a version
> ordinal corresponding to a new line of development: 1.13, 1.14, … that method
> throws away that version ordinal and replaces it with the one for the 1.12
> line.
> Since the current {{support/1.13}} and {{develop}} branches have the bug
> upgrading a current 1.13 to 1.14 or a current development/1.14 to 1.15 would
> exhibit the same behavior (locator apparently stuck at the older version in
> the view.)
> Ramifications of this incorrect version indication in the view are TBD.
> Whether or not this situation resolves itself after _another_ round of
> restarts is TBD.
