The resolver collects previously known incompatibilites and sends them to the provider. But previously the provider does not correctly exclude the currently-installed candidate if it is present in that incompatibility list, causing the resolver to enter a loop trying that same candidate.
This patch correctly applies
incompat_ids
when producing anAlreadyInstalledCandidate
to exclude it if itsid()
is in the set.I’m hesitant to add a test since it would hang the entire test suite if it fails. Is there a way to set a timeout on a pip call instead?
Fix #9841.
