Re: [argouml-dev] ArgoUML and GitHub

Message This is a non-trivial task. There are actually over 60 (!) repos with
hundreds of mailing lists and thousands of contributors/followers plus 15
years (!) of history.


Having said that Tigris has long been marginalized by the other forges and
since it stopped accepting new projects last year, it's probably just a
matter of time before it closes.

There are actually three separate but related decisions to be made:

1. Choice of SCM - SVN, git, Mercurial (hg)
2. Choice of forge - Github, Bitbucket, Sourceforge, etc
3. Choice of ancilliary tools - mailing lists, issue tracker, wiki, etc
(this usually defaults to whatever is provided by the forge, but doesn't
have to)
4. If the lists of committers is going to be changed, that's another
separate decision

I don't think there's any question that git or hg would be better than
SVN. I mostly use git, but I know hg has its supporters. Github is git
only, but Bitbucket and Sourceforge give the option of choosing Mercurial.

I use Github for other projects and, while it's certainly popular, it's not
without its weaknesses. The issue tracker in particular is pretty weak and
it'd be worth considering whether to use Jira or some other alternative

Transitioning mailing lists will be eased to some degree by the fact that
their archived in MarkMail and the new lists could just be added to the
current archives, but the thousands of subscribers would need to
resubscribe (or not).

Choosing not to migrate the issues would mean abandoning a pretty
significant piece of the project history. That's not a decision to be made
lightly. I've successfully used my tweaked version of this script to
migrate issues to Github:
https://github.com/a​rthur-debert/google-​code-issues-migrator​/pull/18 and
Tigris has a way to dump all issues in XML e.g.

Although Github has a nice easy to use SVN importer (you just give it a
URL), it can't deal with the ArgoEclipse SVN repo on Tigris, so almost
certainly won't be able to deal with the main repo which is many times
larger and more complex, so the migration will need to be done using
svn2git locally (probably followed by a bunch of handtweaking/pruning to
get rid of large binaries, etc).

I'm supportive of migrating (although I'm sure there are some that will be
nostalgic for Tigris since ArgoUML has been hosted there for 15 years
but you shouldn't underestimate how much work it'll be.
