RE: [wtp-dev] The Big Picture
|
Hi Konstantin,
Thanks for building this tool - the
graphs really help to provide an overview of the dependencies and should
generate some good discussion. I also have a home brew tool that scans
for dependencies and provides information on references, calculates install
sizes, etc., so maybe we can find a way to collaborate.
> I
then ran my utility against 3.0 M1 installation which included WTP SDK
and WTP automated tests.
We may want to compare without test
plugins as well - I know in some cases teams have built test harnesses
that aren't strictly component specific, e.g. a test that extends WTP like
an adopter to test extension points and interactions across components.
We'll need to examine these dependencies to understand if they are valid,
mistakes, or if there is some restructuring that should occur. All of this
should be done in light of the installable options we want to provide in
addition to our current features and new component definitions.
I have to send my regrets for today's
call, but David will be announcing the formation of an Architecture Working
Group. I'll setup a call next week so that we can start talking about these
issues, update our current docs, and decide what work needs to be done.
Thanks,
Tim deBoer

One of my goal was to better understand
the new organization as specified by the project refactoring proposal,
so using existing features would not work for that since they have yet
to be updated to reflect this. Part of this process (at least as far as
it applies to common) is to drive the creation of new features.
So... If you look at the component
listings in my e-mail, you will notice that WST and JST parts co-mingle
(just like they do in the project refactoring proposal). Now, if under
each of the new projects we define a WST and a JST component and graph
dependencies of those components, then we would not end up with any cycles
(the build works, as you point out). Is that good enough? Is it ok to have
cycles at project-level as long as we can define components such as no
cycles would exists? How would you build such a structure once the codebase
is re-organized based on the project refactoring proposal? We wouldn't
be able to have a project-level build since a top-level driver would need
to know how to weave builds of components of different projects such that
cycles are avoided.
The Java EE <-> Common cycle
is due to jst.common.frameworks depending on wst.web. This seems wrong
to me. This builds right now because by the time jst.common builds, all
of wst has been compiled, but I think jst.common should only be able to
see wst.common.

I'm not sure I understand, but if you are saying that Common depends on
Java EE, then I think something is amiss.
The way our build works, it wouldn't compile if that was the case.
Does your analysis also take into account the WST/JST split?
I think the way to approach this would be more along the lines of our defined
features?
Or, am I simply not understanding?

So in my quest to understand the "Common Project", I've been
writing a little utility that can analyze plugin dependencies and produce
a component-to-component dependencies (given component definitions). Until
today, I've been mostly focused on understanding how the rest of WTP depends
on common, but today I decided to let my utility show me the rest of the
picture. Attached is the result.
I knew the dependency lines were not going to be clean, but I was a bit
surprised by the result. There are four simple circles that can be easily
spotted...
Java EE <-> Common (yikes!)
Java EE <-> EJB
Java EE <-> Server Tools
Java EE <-> Web Services
More complicated circles are also present, but these are harder to spot.
One example is Web Services -> EJB -> Java EE -> Web Services.
It strikes me that we either have a lot of work ahead of us on refactoring
the dependencies or these boxes aren't quite right. Maybe a bit of both.
Thoughts? Does any of this come as a surprise?
I used information found in http://www.eclipse.org/webtools/devProcess/wtpProjects/Refactor%20WTP%20Proposal.pdf
as the definition of the component boundaries. I then ran my utility against
3.0 M1 installation which included WTP SDK and WTP automated tests. Let
me know if the component membership as listed is not accurate and needs
to be tweaked. The only two plugins that are not accounted for are org.eclipse.wst
and org.eclipse.jst. Not sure where these would end up.
