Re: [eigen] git

[Benoit Jacob <jacob.benoit.1@xxxxxxxxx>]

and thinking more about it, and discussing with Thomas: this operation
is really bad for KDE's SVN server.

it's downloading 30% of all of KDE's history when really there is no reason to!

So I stop it.
- either there's a way to convert from svn to git without checking all
revisions in the given timespan, only the revisions that matter for
the given directories;
- or we use Mercurial.

Again, the problem didn't exist when converting only trunk/kdesupport/eigen2.
The problem seems to be that the "greatest common divisors" between
our trunk,branches,tags in SVN is the root.

Cheers,
Benoit
