CLOUDSTACK-10377: Fix Network restart for Nuage by fmaximus · Pull Request #2672 · apache/cloudstack

fmaximus · 2018-05-24T10:03:01Z

Description

Changes in PR #2508 have caused network restart to fail in a Nuage setup,
as the new VR takes the same IP as the old one, and the old VR is still running.
Nuage doesn't support multiple VM's having the same IP.
We delay provisioning the interfaces in VSD until the old VR interface is released.

You can use BooleanUtils here.

The null check is on answer, not on answer.getResult().

Would you mind extracting these blocks of code to specific methods and unit testing them? Some documentation might help as well.

This is a comment to for this PR only: We really need to change our mind set and start using smaller, concise, well-documented and unit-tested methods. This in turn can greatly improve our productivity.

+            if (!Boolean.TRUE.equals(vm.getParameter(VirtualMachineProfile.Param.RollingRestart))) {


You can use BooleanUtils to evaluate vm.getParameter(VirtualMachineProfile.Param.RollingRestart))

Then I would have to cast, as vm.getParameter() returns Object

rafaelweingartner · 2018-05-25T10:52:16Z

                super.deallocate(network, nic, vm);
            }
+
+            if (virtualMachine.getType() == VirtualMachine.Type.DomainRouter) {


Can you extract this blob to a method?

Do we really want to go into creating methods for checking enum values?
I'm not in favor of creating that kind of method in this class,
so it should go either in VirtualMachine or in VirtualMachine.Type

I am pretty sure @rafaelweingartner means the entire if block and not the enum check, @fmaximus

Spot on. I was referring to the IF body, and not to the IF condition. We really need shorter methods and more unit tests.

yadvr · 2018-05-29T10:40:03Z

@fmaximus can you address outstanding review comments?

Address review comments

yadvr · 2018-06-04T07:53:30Z

While one comment around refactoring code to a different method is outstanding, @fmaximus can you comment? I'm okay to merge this in order to unblock for RC2. /cc @PaulAngus @DaanHoogland

fmaximus · 2018-06-04T09:17:09Z

Still was running some tests on the refactoring.

ok by me @rhtyd should it be packaged and smoke tested again? I saw you started that

It's good!

@PaulAngus I did a walk through and am fine to merge this one, ok?
