Re: [cdt-dev] Re: New Debug Model (was: Editor technology subgroup)
|
Hi Mikhail,
A simple answer is GDB. A more accurate answer is little involved:
In our commercial product, where the base design for our prototype was
lifted from, we use an out-of-process back end which could run on the
same or different host... just like gdb. Also the protocol that we use
to communicate with this back end is GDB/MI with extensions... lots of
extensions.
As far as the prototype itself. For most of its development, I used the
Push Down Automata example back end, which has a very simple text-based
protocol that carries over two socket data streams. And relatively
recently, Ted took the prototype and ported it to use GDB.
That said, the most mature part of the prototype is the framework that
the different components use to communicate with each other. The
specific interfaces for back-end communication, representation of
threads, stack frames, etc, are just place holders, even for the GDB
back end implementation.

Hi Pawel,
A quick question. What are you using as a backend?
Thanks,

Hi All,
I'll start off by apologizing. I've been meaning to edit the
http://wiki.eclipse.org/index.php/DSDP/DD/DebugModel 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.
-Pawel
P.S. I just signed up for dsdp-dd-dev and cdt-dev... better late then
never.

Hi,
while Doug Gaff is at the WR User Conference in Orlando,
let me go ahead and start the new thread :-)
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.
Cheers,
Martin

Hi,
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.
Thanks,
Ewa.

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...

Doug,
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
doing
some work in this direction. Is there any new information
available on what
they are doing?
Thanks,
Mikhail Khodjaiants

Doug,
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
portions
of CDT
debugger functionality in the parallel debugger
implementation, it would
make sense to try and combine efforts here.

Hi folks,
I've asked Toni Leherbauer from my team to provide input
on the
editor.
Toni is currently looking at enhancing the CDT editor and is
collecting
some features on the CDT project plan.
http://wiki.eclipse.org/index.php/CDT/planning/4.0
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
discussing
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
Eclipse
3.2
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
weeks
so that the community can start discussing architecture,
interfaces, and
requirements.
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).
Doug
