[Geoserver-devel] [Geotools-devel] Discussing a switch to a time boxed release model

Hi all,
I really would like to move forward with this proposal.

I’m currently having a lot of difficulties to get an idea of a plan on wich version of GeoServer/GeoTools schedule on my projects, so having a programmatic release project would be very welcomed and useful.

High automation also is a great idea, would very very helpful for the release process which usually takes a lot of time and resources.

I also volunteer to provide help as much as possible to have all of this implemented soon.

Regards,
Alessio.

In general I think it looks great, a few things though. I think given the current effort to put out releases 1 month is probably asking a bit much given the resources we have on the project. So I think to do one month cycles we really do need to better automate our release process with a hudson job that does most of the work.

It would also be good to have some better defined (and perhaps stricter) guidelines about what is acceptable to commit given the current phase of an iteration. For instance obviously once we move to a stable or hardening phase GSIP’s that drastically alter the core are out of the question. It would be good if we had a more concrete definition of “drastically alter the core”. Like should we be strict and say stable/hardening means strictly only bug fixes? With a faster release cycle it could make more sense to have stricter guidelines since if you don’t get something into this release there is one not too far off. This is exactly why we ran into the fluerry of gsip issue… with another release 1.5 years away it certainly puts the pressure on to cram stuff in.

Anyways, great stuff. I like where this is going, big things from my standpoint.

  1. better automation of release, which i am happy to help with
  2. better guidelines for what type of development is acceptable during what phases

Fully agree on the higher automation (tried to discuss some ideas about it in my
original mail).

About what is acceptable and not, what about the following:

  • stable series: only bug fixes and new features that do not require API changes
    or large patches to existing systems (that is, if you are contributing a new module
    the patch can be as large as you want, but a “bug fix” that rewrites half of WFS
    is not welcomed unless the PSC really really wants such change badly in)
  • trunk: free reign, but large changes still need a GSIP and reviews
  • hardening: no new features, only bug fixing to make sure people concentrate on
    that, if you have something new it has to go on trunk for the time being

The above should be, imho, taken more or less as strict rules that the PSC should
try to enforce (the above, or whatever we come up with).
That said, the PSC should be allowed to decide outside of the above rules
in case of dire necessity (e.g., something that could threaten or damage the
project severely if not done outside of the rules).

Cheers

Andrea

+1 on all this.

Perhaps two GSIP's should come out of this? One for the release model
/ schedule. And then another for automation improvements? Or perhaps
we don't need a GSIP for that, but should get a jira and a plan of
attack for it.

We can have two GSIPs, first the automation one, once it’s there we
can do the release schedule one?

I can help for the automation one too (within the limits of what
can be done without direct access to the build server, that is).

I am not sure we need a full blown proposal for the automation stuff, but i guess it can’t hurt, if anything it will help specify what the imports/outputs are. In my head the idea is to have a new job that takes a revision and a README description and basically that would be it. A bunch of core artifacts would spit out the opposite end.

Taking it further will be automating the osx and win installers jobs, for which we have machines that would be suitable for this already.

I am happy to script it out, if i find i can’t do it in a reasonable amount of time I will try to find some help. I actually would like to store all of our build scripts from hudson in version control anyways so anyone can hack on them easily, this seems like a good time to do that.

Yep, that sounds cool. Let me know how I can help.

I also agree I don’t see the need for a full blown GSIP, maybe better to use the time to hash out the scripts.
The time boxed model instead really needs a management comitee vote, thus we’ll really need to make a proposal for it.
