[Ardour-Dev] Issue 0007157: Cannot move an automation curve together with a region

[Tobi Stadelmaier]

Hi everyone,

I'd like to make you aware of the issue above, since it bit me personally,
but more importantly, I think it's something that might well break someone
else's workflow.

Effectively, the checkbox that says "move automation together with regions"
in the preferences is ineffective in recent Ardour versions - it broke just
after 5.0, and has been broken ever since. With a current version, you
can't have Ardour move the automation of one track together with your edits
of the regions any more. No matter if you have that checkbox set or not,
the automation data of a track stays where it is, even when you move a
region (or ripple-delete it, for that matter). Which I think certainly has
the potential to be a major pain for certain users.

The workaround that did it for me is to consolidate the track _before_ you
move things around, but that's really only a workaround for sure.

Anyway, I bisected it to a certain commit, and double-checked whether this
really fixed it for me - details are in the bug report.

Now, while I'm now personally running a patched version of 5.5 that solves
it for me, I am really a bit uncomfortable with the alleged "fix" - the
commit in question clearly tried to fix _another_ thing, which is not a
factor in my personal workflow (since I don't use midi), so I'd be much
more comfortable if someone who knows their way around the region.cc file
could take a look. Quite honestly, I have no idea what the commit in
question tried to do in the first place. But I'd be glad to learn :)

Of course I'll be happy to help (bear in mind that I'm a Java person,
though, and was basically banging my head against the keyboard until it
worked for me again :)) But I'd certainly be able to help with testing a
real fix, do some more bisection, or whatever. Just let me know.

Cheers,
Tobi
