TurboGears 1.5 development plans
Chris Arndt
here are the plans Christoph Zwerschke and I came up with for future
development of the TG 1 branch.
Feel free to dicuss, give suggestions and comments!

TurboGears 1.5 Planning
=======================
Team
----
- Ken Kuhlman
- Christoph Zwerschke
- Christopher Arndt
- who else?
Release manager role shared by Christoph Zwerschke and Chris Arndt
Project Infrastructure
----------------------
- Reclaim SVN repository?
- Migrate Trac and SVN to new server
- Separate tags/branches/trunk structure for TG1 and TG2
- Revive turbogears-trunk and make distinction between users and
development
mailing list clear.
Development Process
-------------------
- Commit to 1.5 branch and back-port to 1.1 branch
- Only backport to 1.0 branch if *really* necessary (ticket required).
- Use more branches
New Features
------------
- CP 3.1 support (Ken Kuhlmann)
- Genshi support for TG widgets (Christoph Zwerschke)
- (Start) Sphinx docs (Chris Arndt)
Refactoring
-----------
- make util module into a a package
- remove feeds package
- deprecate scheduler package
- reorganize quickstart templates (Chris Arndt, already started)
- database options loading
- lazy template engine loading (Chris Arndt)
Maybe:
- refactor commands package
- refactor i18n package (maybe replace with Babel?)
- rewrite test configuration loading
Plans
----
- TG 1.1.1 release in 2nd half of November (I have added a milestone
in Trac and started moving tickets into it)
- migration of TG Trac and SVN to dedicated server afterwards
- present development plans on mailing list (this is what you read
now)
- Start discussion about the relationship of TG 1 and TG2 and the
(poor) maintenance state of the TG2 branch.
- TG 1.5 alpha release planned for early January 2010

Why is this necessary? Can't the 1.x branch stay where it is currently?

What exactly needs revival? turbogears-trunk is alive and well AFAIK.
Or you mean an ML that is dedicated to the 1.x branch?

I'd say once 1.5 is out 1.1 users should be encouraged to migrate to
it. Back-porting things is a pain and if everyone is told that they
should use the latest stable release back-porting will not be so
important. I have been using tg from 0.9 or so and have always
upgraded to the latest stable release without lot of issues, now I'm
at 1.1. If everyone does this we can save lot of time for you guys by
not requiring back-ports.

I'd say this shouldn't happen and if people are made understand that
this indeed is not a priority people will either be happy with the
current 1.0 or migrate to 1.5 (once it's out).

Oh wait! And what should we use instead? I'm currently heavily relying
on the scheduler module, but if there is a better alternative I'd be
happy to migrate.

If this would make writing custom tg-admin commands easier, I'm all for it.

SVN reorganization is another matter to be dicussed separately (e.g.

sth on turbogears-trunk in the past months and didn't get any answers
or very little feedback. I get the impression that many devs do not
even read turbogears-trunk properly anymore. I also think we should
make a clear distinction between the main list for *users* of
TurboGears (i.e. people developing *with* TG) and turbogears-trunk for
TG developers (i.e. people developing/contributing *to* TG). It would
be better, IMHO, if the lists where called "turbogears-users" and
"turbogears-devel", but it would not be practical to change this at
this stage.

lists for TG1 and TG2? for the moment, i think not. But we should
evaluate this again in a few months.

I just meant to say, that commits should go to the TG 1.5 branch by
default now. But we need to maintain the 1.1 branch for a while, since
CP3 will introduce some changes, which makes porting your apps a
little bit more involved than a 1.0 -> 1.1 migration.

That's why there needs to be a ticket for every commit to the 1.0
branch, so the importance of the patch can be evaluated.

this topic (you DO read the trunk ml, do you? ;) ).
Chris
Daniel Fetchinson
Yep, I did read that post :)
It was not clear from the item 'deprecate scheduler package' that you
simply mean to replace the shipped tg scheduler module with this
external one. This change would of course be fine!

in "maintenance mode" and 2.0.4 will come out only if a security
release is needed.
http://bitbucket.org/turbogears/tg-dev/
http://bitbucket.org/turbogears/tgdevtools-dev/
and
http://bitbucket.org/turbogears/tg-docs/
have had a ton of changesets.
Are you still looking at the svn repository for this?
Ken Kuhlman
Project Infrastructure
----------------------
- Reclaim SVN repository?
+1. TG2 isn't using the trunk, so it should be recycled back into the 1.x line.
- Migrate Trac and SVN to new server
- Separate tags/branches/trunk structure for TG1 and TG2
- Revive turbogears-trunk and make distinction between users and
development
mailing list clear.
+0 This was more important when the TG community was larger, but it's still a good idea. I doubt that we can put an end to chatter about alpha & pre-alpha releases on the user's list, though.
Development Process
-------------------
- Commit to 1.5 branch and back-port to 1.1 branch
Sweet. I'll post an updated diff between the branches to #1955 ("Ensure 1.1 changes get applied to 1.5") and then close it. (Just as soon as we get that test_json issue fixed).
+10.
Also, I don't think I'm going to make 1.5 for #1952 ("Backport RESTful dispatch"). Should I move it to 1.x?

Sure. But one of the main reasons why people use the TG1 branch is that
they do *not* want to migrate, because it is time consuming and error
prone. I have projects which make heavy use of TG widgets; migrating
them to TW/TW2 would be a major issue. If I did this, I could just as
well migrate the whole app to TG2. And it's just incosistent that the
default templating engine of TG>1.1 is Genshi, but widgets can only work
with Kid. Using Genshi page templates with Kid based widgets also leads
to some nasty compatibility issues: ET(...) needs to be called. This is
done automatically in newer versions, but it's still ugly.
Independent from that, TG1 should of course also support TW/TW2.

against moving TG1 into hg anytime soon.
To be honest, I was never happy with the way the decision of migrating
TG2 to hg decision was made and I still don't see what advantages it
has brought. On the contrary, there exists considerable confusion now
where the official repo is (do the 2.0 docs even mention the hg
repository?) and it is poorly maintained (e.g. missing tags for
official releases).

not archived properly, unstructured and hard to search. Ideally,
development discussion and decisions should be documented in the docs
or the ticket system, but a mailing list is the next best thing.

- There are more than 30 tickets pertaining to TG2 on the turbogears
trac, which have not had a milestone assigned and it looks like they
are not being attended to
See http://trac.turbogears.org/query?status=!closed&group=version&milestone=&milestone=__unclassified__&order=priority
I mentioned this several times on the mailing list, but nothing
happens.

Exactly. I don't need tw/tw2 at all, I'm perfectly happy with tg
widgets. Currently I'm using kid but I actually might migrate to
genshi for performance reasons at which point genshi support for tg
widgets would be great. But in the foreseeable future I'll be
perfectly happy with kid and tg widgets as is.

+1 In an optimal world a large chunk of the development discussion
happens on the mailing list. That way users who are interested in the
development process (like me) have all the information they need in a
simple archivable and searchable format.

Methinks no. Instead we should create a 1.5a1 release milestone and move
tickets into it (one at a time), about which we are confident that we
can resolve them before this release.

You are so right about this. For starters, I'm not even *allowed* to go
to IRC at work. So from the about potentially 16-18h a day, I could only
stay on IRC for about half of them. But then there is the issue of
timezones, the fact that permanently following a chat in the hope of
something interesting or relevant happening is massively distracting (to
me at least), the interleaved discussions of others...
I don't mind the occasional IRC conference. But even that I can't
guarantee to attend. Real Live and such.
And where are the results of those discussions you guys have? Can I read
them? Can I comment on them? Can I *work* on them? No.
So I'm feeling I'm cut out of the development efforts. The public
visibility of those is reduced, as no one can follow discussions and
decisions by searching through ML or TRAC. Which might give the
impression to others that the project isn't very much alive.
For me this resulted in not doing anything anymore, except fixing maybe
concrete bugs I encounter when working with TG2.
The whole HG vs. Mercurial issue I also don't see as benefitial - but I
can cope with it.

Daniel Fetchinson
I guess you mean svn vs. mercurial.

The reason why the move isn't finished is because we are waiting on an
upgrade of the turbogers account to point hg.turbogears.org to it. Yet
again another topic not for the main list.

didn't explained myself correctly. I'm not saying we are going to
replace the ML with irc. I'm just saying a lot of discussion has
happen on IRC which reduced the traffic of the ML.

been moved there. All mayor changes had been discussed in the list.
I do agree with what you say and from my part I'm sorry we should
indeed use the ML more to report some bugs for everyone to see,
although other things are way better in a faster feedback channel. For
example the recent content-type bug will not be fixed if we didn't had
people on IRC discussing it.

checkins you see the more active a project is. Yes ML and trac help
with the impression but a project that is getting tons of tickets is
not more active than a project that is getting tons of checkins.

"TurboGears2" entry on PyPI, Florent must have added me while he was
adding me for the "TurboGears" entry. I'll add you as soon as I have
access to my PyPI login data. What is your PyPI account name?

it be. I hung out there the last couple of days in the evening, and nothing
was really happening.
But to be honest: even for support, I'd prefer if people would give it on the
ML.
Because there it is persistent, visible, and searchable, linkable. So IMHO
those giving support there should consider moving that support over to the
ML. Which I can't force anybody to do, but maybe the core devs and supporters
can ponder this.

benefitial in a concrete situation such as fixing a bug - I've done that
numerous times with Florent over IM.
But for others to report and see if bugs are reported, IRC (or any other
non-archived form of communcation) isn't the right thing. See above.

find it. Which might mean that I'm to stupid for the whole
bitbucket/HG-thing, but when I look at
http://hg.turbogears.org/tg-21/
I see the last checkin being 4 months ago. If I'm supposed to look anywhere
else, pray tell me. But please do *not* tell me that I've got to look at all
forks. That they exist is of course perfectly fine - but frequent
back-integration is crucial to prevent doubled or worse, conflicting work.
