Subject upgrade path 4.1.1 -> 4.2/master
Date Thu, 01 Aug 2013 11:59:25 GMT
H,

I am testing an upgrade of my code for sdn based vpc private gateways
(not in the mainstream code). It runs on a custom 4.1.1 based on the
4.1 branch. I have tested it against a 4.0 database and it upgrades
fine.

Now I try to have a master version to which I applied my code to run
against the same environment. I added
        _upgradeMap.put("4.1.1", new DbUpgrade[] {new Upgrade410to420()});
to the class com.cloud.upgrade.DatabaseUpgradeChecker.
I have the systemvm.iso ready on the hypervisors, but not on my
(windows) development machine. When I start my version in eclipse I
get

INFO  [c.c.u.DatabaseUpgradeChecker] (Timer-2:null) Database upgrade

I found that vm_template should contain a line for this;

                    //Get 4.2.0 system Vm template Id for
corresponding hypervisor
                    pstmt = conn.prepareStatement("select id from
`cloud`.`vm_template` where name = ? and removed is null order by id
desc limit 1");
                    pstmt.setString(1, hypervisorAndTemplateName.getValue());
                    rs = pstmt.executeQuery();

Should I add a row by hand?
Is there a readme/howto-upgrade, I should read (or create using my findings)?
Why is this not automatic this time?

sorry if I missed the mail thread explaining all of this,
Daan Hoogland
