Re: [cdt-dev] Re: New Debug Model (was: Editor technology subgroup)

As promised, I started on defining the requirements for an optimal debug model design for embedded debugging. I took kind of a fun approach to the problem, so please let me know if you think it's confusing or inappropriate.

Hi All,
I'll start off by apologizing. I've been meaning to edit the to start collecting requirements, but it seems like such a daunting task that I ended up putting it off week after week :-( So rather than make up more excuses I'll make sure that I get started on it today. If anyone already has a set of requirements written up, please feel free to post them on the twiki page or mail them to the list, it'll make this process a lot easier.

Separately, we have been working on a prototype that we will commit to CVS shortly. This is the same prototype that we talked about in the February DSDP meeting, except we have rewritten it a couple of time since to take advantage of standards that are in JDK 5.0 and in OSGI. At this point, aside from javadocs and example code, the prototype code is ready to commit, we're just waiting to get the required signatures from within the company. So rather than try to describe what this thing is about, I'd rather wait another week or so and just post the code for everyone to look at.


P.S. I just signed up for dsdp-dd-dev and cdt-dev... better late then never.

Yes, Pawel P has made quite some progress on prototyping
against the Flexible Debug Model. Sine quite a bit of this
is based on former WR proprietary code, we'll need to wait
for IP clearance before we can actually make a contribution.

We hope this to happen anytime soon.

I propose starting a new thread for future communications about the
Debug Model since there's a technology subgroup in the DSDP-DD. I would like to leave this thread for Editor enhancement/ideas/requests focusing
on embedded development.

I got confused by all the Dougs. :-) I'd like to work with anyone on this!

Which Doug is everyone talking about :).

Since the Greg's note was sent to cdt-dev, I thought it was for me. This
note sounds like it is for Doug G...

There was a special group formed among others at the last DSDP meeting to work on the design of the debug model. I volunteered to participate, but I haven't heard anything since. You mentioned that Pavel and
Ted are
some work in this direction. Is there any new information available on what
they are doing?

I wonder if we could be involved in the design of the next generation debugger model? We're also looking at how to use the flexible debug model for the parallel debugger. Since we reused considerable
of CDT
debugger functionality in the parallel debugger implementation, it would
make sense to try and combine efforts here.

BTW, Welcome Toni!

We've been in need of some focus on the CDT editor for a while and I

Hi folks,

I've asked Toni Leherbauer from my team to provide input
on the
Toni is currently looking at enhancing the CDT editor and is collecting
some features on the CDT project plan.

Since there is interest in the editor in both the CDT and DD projects, we should keep both groups in the loop. And of course, we should have one editor solution in the end (in CDT). We started
this in
the DD project in Toronto simply as a way to capture requirements as
they related to debugging.

Also, as I mentioned on the recent DD call, Ted and Pawel are working on a prototype for a generic debugger implementation of the
debug model interfaces (EDMI 3.2 for short). The goal
is that this
prototype will form the basis of a next-generation debugger model that benefits folks using CDT and folks working directly with the Eclipse platform today. We intend to get this committed in the
next few
so that the community can start discussing architecture, interfaces, and

So regarding the editor, I see open questions around how we integrate disassembly, breakpoints, instruction pointers, etc. with a new debugger implementation. I am also wondering how the editor will
deal with
multiple debug engines simultaneously (for example, how
to set the
default breakpoint scope).
