GDB 7.1 release planning...

GDB 7.1 release planning...

[Joel Brobecker]

Hello,

Time flies. I didn't realize this, but the tentative date for creating
the GDB 7.1 branch was set to Jan 20th, so only 12 days away from now.
It might be a little tight (or not) depending on what we'd like to have
in this release.

Is there anything that would be blocking for the branch creation?
There is a Wiki page for the gdb-7.1 release:

    http://sourceware.org/gdb/wiki/GDB_7.1_Release

There's been one item for a while but it's about documentation,
which is not blocking for the branch (might already be done too).

Anything that would be highly desirable and would potentially
justify delaying the branch?

Thanks,

I'd like to improve the behaviour on Darwin.  Most of the work has already been integrated and I think the
last submitted patch would go in before the dead-line.
The last known issue is proper handling of common symbols, but this work is not yet ready.  I will see
if I can submit this before Jan 15th.

This makes sense to me. Can you add a reference to the patches currently
outstanding in the gdb-7.0 release page (wiki)? Or, if you prefer, you
can send the URLs to me, and I'll update the page.

OK. If you manage to make a change that only influences Darwin,
and you think the patch is safe enough, you can elect to put it
in the branch as well (your decision as the Darwin maintainer).

I thought about check-in in PIE for 7.1 but it slipped a bit for me now:
	http://sourceware.org/ml/gdb-patches/2009-11/msg00167.html

Going to try to catch up with the schedule (and do a re-post).


Thanks,
Jan

FWIW, I would love for you to check in PIE for 7.1.
Any way I can help?

I see that Tom started looking at the patches again (thanks Tom!).
We should certainly try to review them all before branching.
I'll add a reference to the ones still not reviewed to our release wiki.

My two cents, since I'm not the one doing the work - but I received
complaints that enough Python bits for the GTK filtered backtrace
script were not in 7.0.  How much has been merged since the 7.0
release?

Not very much, mostly just bug fixes.

The filtered backtrace work is not fully baked yet.  We know it is still
missing some needed features, at least.

Is this important enough that we want to make it a priority? Do we know
which pieces need some work.

On a side note, what about the Google SoC work? I think it was about
inferior-events, right? I tried to look at it a few weeks ago, out
of curiosity, but couldn't find which branch it is a part of? Does
anyone know? How far are we from being able to submit the code for
inclusion in the FSF tree? I don't want us to press this feature for
7.1, but it'd be nice to not lose all this work. I volunteer to
clean it up later this year.

I'd say it is the second-most-used Python-based feature.

There are a few bug reports about the replacement for "bt" (this written
entirely in Python).  It doesn't always do what users need.  The details
are in the list archives, I can dig them up if anybody is interested in
working on this.

Also, it doesn't work with MI.

So, while I think it is a worthwhile feature, it needs enough work that
I don't think we should wait for it for 7.1.

I thought it was on a branch in archer, but I don't see it right now.

The author posted a patch series to the archer list.  I had a number of
comments, which nobody has addressed yet.  So, I think it is promising
but not ready to go in.

Right now most of our Python work is in fixing bugs in pretty printing.
I'd like us to get back to implementing new features, and I think that
will happen sometime, but we have a lot of things going on and so it is
hard to say exactly when.

Re: GDB 7.1 release planning...

[Joel Brobecker]

OK - thanks everyone for the feedback.

The tentative release schedule has been officially updated:
  - Branch & first pre-release: Feb 10.
  - 7.1: Feb 24.

I think that the wiki page (http://sourceware.org/gdb/wiki/GDB_7.1_Release)
should be up to date, but do take a look, just to make sure I haven't
forgotten one of your items.

I think my host-side tracepoint bits will, fingers crossed, be mostly in 
by then, but they would be a whole lot more interesting if Pedro's 
tracepoint support for gdbserver additions were also there.  However, I 
don't know schedule for submission of those changes.

Couple of weeks or three, but I've no firm schedule.  12 days
seems tight (the whole of CodeSourcery will be busy that week
with anual meetings or stuck in planes).

I'll just drone on extra long in my preso, that will give you plenty of 
time. :-)

In any case, I think the gdbserver bits are sufficiently exciting to be 
worth pushing back 7.1 by a couple weeks.  Plus we lose some momentum if 
new tracepoint features are in 7.1, but target-side code with which to 
try them out doesn't show up until 7.2.

I think that would be fine - I don't want the dates, which are somewhat
chose arbitrarily on a roughly-6-months-calendar, to hurt certain new
features. We pretty much did the same for Python the last time. Also,
I don't think people are waiting for 7.1 with as much anticipation as
they did for 7.0. It took a lot of time and effort before we were ready!

New proposed dates: Branch & Pre-release: Feb 10. That's 3 extra weeks.
Are you guys pretty confident you can make it? That would put the
tentative a couple of weeks later, around Feb 24 [1].

What is the feeling on the new "MI core awareness" feature that Volodya has posted,
making it into 7.1?

Thanks

I don't feel qualified to answer, but perhaps if I said that I don't
see any problem with that, someone else might step in and give a more
authoritative answer? ;-)

Good chances, I'd say.

Probably, thanks.  Note that we also have further tracepoint
actions and breakpoint commands unification and MI tracepoints
support in the queue.  Eclipse is being enhanced with tracepoint
support and is relying on these changes, so it would be nice to
have them in 7.1 too.  Not sure who has the ball on those,
either Stan or Vladimir, not me, I think.

How come there are no dates on the wiki page?

The dates on the release page of the GDB website... I haven't had
a chance to update them, yet, but I'll do that soon.
