Numpy migration?

Show all headers | View raw

Hi all,

Since a few days, a new RC is stalled in unstable:

 testing: 1:1.15.4-2
unstable: 1:1.16.0~rc1-3

The reason that it can't migrate is that it breaks the CI tests of
several packages in testing. For example astropy (where I am the
uploader), and its dependencies. The CI test failures were caused by
astropy (#917466) and are fixed since a week in unstable.

However, astropy cannot migrate now, to testing, since it depends on the
new numpy version (and therefore can only migrate after numpy). And
numpy is blocked by the CI failure of astropy ...

Looks like a deadlock. Which will be resolved before the migration delay
ends. Which is in the second half of february, and therefore will cause
all packages that depend on numpy and are not in testing yet to be kept
outside of Buster (due to the release timeline).

What is the way to resolve those problems? These deadlocks probably
appear regularly when a package gets a major update: package A breaks
the CI test of the rdep B in testing, and a rebuild of B in unstable
depends on the newer version of A.

Another CI problem is python-astropy, which is the Python 2 version of
Astropy. python-astropy is going to be removed as soon as there are no
backward dependencies left; however there is still some cruft in
unstable that depends on python-astropy. But this should not hinder
numpy to migrate.

How to solve this?

Best

Ole
