Currently integration components, particularly those that interact with the bus, live in
the respective component repos. I have been working with Peter on HAWKULAR-844 to migrate
the bus from ActiveMQ to the default messaging subsystem in WildFly 10, which is based on
ActiveMQ Artemis. While working on this, I started to wonder if all of the integration
components should live in the same repo. Let’s say I make a breaking change in the bus,
then we have to update and cut releases for each of the component repos, which is
currently five or six. If the integration components live in the same repo as the bus, it
is much easier to make the changes and we only have one new release to worry about.
Keeping the integration components in the same repo should also help reduce the number of
dependencies in each of the component repos which makes development on any one of them
easier. I want to know what people think because once HAWKULAR-844 is done, I would like
to consider some refactoring in the bus code to utilize JMS 2.0 APIs including support for
async sending/receiving messages. This would likely entail breaking changes.

Hi John, I was about to write a message on this topic now after I spoke
with mazz :)
integration components, particularly those that interact
with the bus, live in the respective component repos.
I am not 100% sure which are "integration components" for you.
Nevertheless, mazz and me agree to move the "new Bus" (after
HAWKULAR-844) and "new Nest"
(https://github.com/hawkular/hawkular-nest/pull/1 ) to hawkular-commons
git repository. I'll write more about the proposal in the next message.

I am primarily talking about bus integration which would include things like,
* hawkular-metrics-component
* hawkular-alerts-bus
* hawkular-alerts-bus
* hawkular-alerts-actions-bus
* hawkular-inventory-bus-api
* hawkular-inventory-bus
Once we move to WF 10, we will drop the bus subsystem in favor of the default messaging
subsystem. All that remains of the bus is a shared, common library. It will no longer have
(or need to have) any relationship/dependency with the nest. I wonder if the bus
integration components should live in the main hawkular repo. If we have integration tests
involving these components that run in a hawkular server, then I think from a development
stand point, it makes things easier if they live in the main hawkular repo.

Ah OK, this is a little bit different area than I wanted to speak about.
Once we move to WF 10, we will drop the bus subsystem in favor of
the
default messaging subsystem. All that remains of the bus is a shared,
common library. It will no longer have (or need to have) any

I agree that integration tests should be located as close as possible to
the components they are testing, ideally the tests should be located in
the same git repository as the components tested.
However, we cannot move bus-common to HK main, at least because that
would introduce circular dependencies between HK main on one side and
Agent and Command Gateway on the other side.

I think if all that will remain is a common library, which I guess will be located in
hawkular-commons, then it would be better for the integration code to remain with their
components.
Although this work may be disruptive and result in changes in multiple repos, I still see
the bus as plumbing and it should result in a stable API. Whereas the component code that
uses the bus is more likely to change, and therefore it would be easier for the component
developers to have their code in one place.

Gary

Everything has pros and cons.
If we move the glue projects into hawkular repo, yes a change in the bus will be easier to
manager.
On the contrary, a change on the component will need an additional update into the
hawkular repo.
So, synchronization is needed in one side of another.
For alerts, that we relied on the bus for the integration metrics and also internally for
plugins integration we worked fine with the components in alerts repo.
As a change in the bus is rare (like this, once WF10 is out, I don't think a change
here is going to be frequent), but on the contrary a change on these projects are pretty
normal.
So based on how we worked, for us, it would be better to maintain them on the component,
to have all component-related-logic together.
I agree that perhaps it might be parts shared that can be extracted and placed in a
commons location, but most of the logic should remamin in the component IMO.

Similarly, what about the things in hawkular repo's "modules" directory?
Shouldn't those also be moved to the same common repo? Maybe they can't for
technical reasons, but it think we should at least look into it, especially if we are
considering moving components to a common repo.
