What was the end-user or developer problem that led to this PR?
See #6355 for the original problem.
What is your fix for the problem, implemented in this PR?
#6355 turned a crash into a nicer error. This commit auto-heals the corrupt lockfile instead.
In this particular case (a corrupt Gemfile.lock with missing dependencies) the LazySpecification will not have accurate dependency information, so we have to materialize the SpecSet to determine there are missing dependencies. We've already got a way to handle this, via
SpecSet#incomplete_specs
, but it wasn't quite working for this case because we'd get to@incomplete_specs += lookup[name]
andlookup[name]
would be empty for the dependency.With this commit we catch it a bit earlier, marking the spec containing the missing dependency as incomplete.
(I had originally opened #6399, but misunderstood a few things there. I closed it and then force pushed to the branch, preventing me from reopening it.)
