As I wrote earlier last night, I restarted the calculation, pushing the limits to maximum. It took 20 minutes for graphviz to calculate. Here's the result: http://py2graph.infomaniak.ch/py2.7.deps.svg As you can see the graph is big in size (a large 11 MB svg file), and large in the screen (it doesn't fit on my work's 38" screen). It's also very hard to interpret, because too big. The consequence I see with it, is that it's going to be really too slow and almost impossible to do the Py2 removal the correct way in just 2 years of time. This reinforce my first impression that we unfortunately must allow ourselves to break reverse dependencies when doing the job, even if we should, at least, attempt to first remove Py2 from leaf packages as much as possible. > I think a transition tracker would also be useful (start at the top > level, not the bottom). I'll ask the release team to set one up. Thanks, that'd be indeed super useful, thanks for it. Hopefully, more than this huge graph that hardly helps the decision making process.
