→Things to tweak in the repository conversion

:There was also some cleanup I performed after the CVS -> SVN switch, which in retrospect is not nice to have in the history. E.g. I cleaned up various branches, and many SVN properties. So commits like <http://scummvm.svn.sourceforge.net/viewvc/scummvm?view=revision&revision=20471> would be nice to suppress. Those SVN properties wouldn't be visible in git anyway, I guess. | :There was also some cleanup I performed after the CVS -> SVN switch, which in retrospect is not nice to have in the history. E.g.

::Property change commits can be pruned with filter-branch --prune-empty | |||
:Also, what about fake branching commits created by cvs2svn, like <http://scummvm.svn.sourceforge.net/viewvc/scummvm?view=revision&revision=3488>, can we get rid of those, too? | :Also, what about fake branching commits created by cvs2svn, like <http://scummvm.svn.sourceforge.net/viewvc/scummvm?view=revision&revision=3488>, can we get rid of those, too? | ||
::Many of those actually change things (like updating version numbers or removing files), so probably not all of them. | |||
:Also, I think when we made the CVS conversion back then, something went slightly wrong with the very old history. Consider e.g. <http://scummvm.svn.sourceforge.net/viewvc/scummvm/scummvm/trunk/?pathrev=3486>, where the code that should be in trunk is hidden away in a subdirectory "scummvm-old" of trunk. Not terrible, but certainly annoying. Esp. since later on, at some point the two are mixed: Trunk is populated but "scummvm-old" is still there.This happened in revision 4785, see <http://scummvm.svn.sourceforge.net/viewvc/scummvm?view=revision&revision=4785>, and while it lists me as the committer with commit message "Initial revision", I am not quite sure why that is... probably because we switch to a new CVS repository back then, with a revised file structure... And things were never properly stitched together. The annoying part is that "scummvm-old" is still visible much, much later, see e.g. <http://scummvm.svn.sourceforge.net/viewvc/scummvm/scummvm/trunk/?pathrev=18000>. It was only removed in revision 20419, see <http://scummvm.svn.sourceforge.net/viewvc/scummvm?view=revision&revision=20419>, manually. | :Also, I think when we made the CVS conversion back then, something went slightly wrong with the very old history.
