Hi Ben, Hi All,

I'm quite conservative when it comes to relying on others' infrastructure so I need some help making me take the plunge. Please see below:

Moving the Subversion repository to a more reliable host (which likely means migrating to Git) would also cut down on the false positives Travis reports because the Subversion server has a habit of dropping connections.

btw, Did you know that github supports subversion clients since 2011 [1]?
Here are supported features [2]. Are these sufficient for your
current svn workflows?
Potentially we could have ONE repository and those liking subversion
can stick with it and those liking git can use that. Of course, this
would need to be proven.

Ah, that's interesting. So my concern is whether github is a safe long-term bet. Specifically what is there to prevent some third party from buying github, or of github going public and the board taking the decision, or github on its own, deciding to charge for hosting, keeping the data hostage to extract payment? What safeguards are in place to prevent this? I'm not interested in "this will never happen" arguments. I'm interested in hard data please.

[4] Provides pragmatic advice for cutting over. Esteban appears to
have done similar to step 1 and 2 [3] - but it seem sometimes his
modifications directly update this mirror so its not clear to see when
that branch is an *exact* copy of the current svn trunk. So I'd love
to see a github repository that is always an *exact* mirror of the svn
repository, with any pharo mods occurring in a branch off that. Even
better if the repository for svn users resides on github in place of
that mirror.

I've been googling around for problems reported using github via an
svn client, and haven't found any smoking guns.
Is this something we can trial? I'm willing to put some effort into
it. A key requirement would be not interrupting Eliots work on
Spur-64. Potentially we could stay for months on step 3 [4] with the
CI infrastructure running on the git side, but code check-ins
continuing onthe svn side.

btw2, [5] provides a use case for the advantages of a full switch.
