Using git

[Brent Atkinson <br...@gmail.com>]

I saw the conversations fly by on dev@archiva and it got me thinking... how
difficult would this be for continuum and what is involved?

Brett do you know more about this or who an appropriate contact would be?

Do you know if this is a big undertaking or a fairly simple matter of
conversion?

Louis,

Thank you for offering your feedback. My understanding so far was that we
were talking about the relevance and logistics of the different ideas. It
did not make sense to talk about schedule quite yet because it wasn't clear
we would want to do it. Also, I didn't think we were talking about making
major changes to the implementations necessarily.

The git migration is a source control-only change, it does not include
changing continuum's support for git. The talk about svnpubsub, the parent
pom and Apache CMS was in response to my query about what effects migrating
to read/write git would have on how we manage the rest of the project. It
should not affect functionality.

The source code reorganization would be about moving the code around to
redraw the module boundaries. While there might be functionality impacts
due to the scope of what would be changing, it would mostly be moving code
and not rewriting it (for now).

I think it makes sense to talk about release timing, but it probably makes
sense as a separate thread still.

Should all the initiatives under discussion be combined into a major
project?  Make this Continuum 3.0?  Include full GIT support, move to GIT,
re-factor (per the other thread), move reports to Apache CMS... Seems like
a HUGE amount of work has been discussed when you collapse the various
threads here.

How large is the Continuum user base at this point?  How would this impact
them?  What would the upgrade path be?

>From my point of view, I have nearly 300 projects (200 or so "active) in
one of my clients SDI.  With nearly 2 dozen support libraries, 10
multi-module,  80 "under development" up to the 64 in production.  Releases
are done almost daily.

A major "upgrade" impact would be something we would have to carefully
schedule - but it would actually be easier than 4 or 5 smaller ones.

Just random thoughts from the old man who hasn't had enough coffee yet...

Really no effect there - svnpubsub is still used for the site publish, but it's a checkout from a separate SVN repo. Likewise, the parent POM is published to an artifact repository, so that's the same.

Whether the site & parent POM get moved to Git or left in SVN is something to decide. I'd suggest just starting with the main trunk and approach the others later if needed. For example, we might later decide to use the Apache CMS for the site instead of a Maven project, and in that case the parent POM probably isn't needed.

I think the steps are:
- hold a vote here
- if passed, ask infra to convert the repository and coordinate with the list
- once done, go through the POMs, developer and contributor documentation and make sure repository references point to the new location

As always, I'm happy to help - I just don't have cycles to drive that at the moment.

Cheers,

That is encouraging. I am happy to do this myself if people find it
valuable. The project is already converted to git as you said. However, how
site publishing and the parent pom fit into this is not clear to me. Not
knowing the ins and outs of the Apache-specific processes like svn pubsub
and how and when parent poms are staged (just for example), it is not clear
what effect if any moving to git would have. I am more than happy to figure
it out, though I may need help identifying the most relevant channels to do
it.

The conversion itself is very simple (the read mirror we already have becomes write). The main thing is doing the work to update documentation, CI, release process, etc. afterwards. If you're willing to do that, or can locate a volunteer, then by all means put forward a vote to switch :)

Cheers,
Brett
