i thought it would just fail silently and tell you at the end what it failed to fix and you could do it yourself. i guess the thing is you can't abort the whole process if one package fails because others might still work without that package? as i don't have twisted-2.0 and zope installed, i'm not quite sure how the dependencies with those packages work out in python-updater. any of the other python devs care the comment?
I'm using depreorder.py within ghc-updater, which is a near-clone of python-updater, and I also discovered that the dependency ordering isn't correct. If I understand the code correctly, it fails with nested dependencies. Assume package A depends on B, and package B depends on C. Then the original code will create a list [B, A, C, B], and then remove duplicates yielding [B, A, C], which is obviously wrong. I've patched depreorder.py to use a topological sort of the dependency cache instead. I hope that the code is correct. It at least seems to work in the few limited test cases I've put it through. Would be nice if you'd consider this patch for inclusion. Cheers, ks
Created attachment 68252 [details, diff] the patch for depreorder.py
Thanks Andres, added your patch to python-updater in 2.4.2-r1. Not going to change the ctrl-C handling at this moment.
