Thanks for the confirmation, and "will do". I still think it is silly as the
discussions on debian-r also revealed that the '>= 4.6.0' on the client
package is sufficient but I acknowledge the change in (upstream) R.
So 'breaks', which we used before, are probably applicable.
But I still have some questions and would appreciate pointers:
- Where did you get the 1.2.0-1 from, i.e. why not the (naive) 1.2.0-1 from
the last version
- I am a little overwhelmed by the list I am confronted with given that
r-base-core is a popular package:
https://qa.debian.org/excuses.php?package=r-base
Is there a way to extract the 'commonalitites' or I have to 'click and
read' any red regression?
- Related, should we add other packages? My onw analysis using testing and
unstable found a few [2] on the client side. Conceivably I could do this
again forcing testing to identify breaks candidates. Or are we content to
survive the onslaught from autopkgtest and move on?
- Also related, what on earth is going on with (Emacs) ess for it breaking?
In short, what is an efficient way to get to the complete list of breaks we
need?
Worst case I can upload a -4 with the breaks for rlang, and we collect the
pieces afterwards and make a -5 (and -6 and ...). It will converge
eventually. But there likely is a better way.
Cheers, Dirk
