Thanks, I updated the title to cover all 3 places.

2 branches + 1 follow-up and it's ready for review.

@oleq since we won't be tackling #5875 soon, can you add a PR with instanbul ignore directive for the upload package?

[oleq]

Are you sure this is the right thing to do? This is a real case where we don't have coverage because we don't understand how the code works. This is a good reminder that we need to address this issue.

[mlewand]

I hear you, that being said, I don't think we have the time to investigate it properly now. So marking it with an ignore and giving a reference to #5875 sounds like a sane idea. I'm not sure whether #5875 is severe enough to put it in the next iteration or should it stay in our todo list. @Reinmar what's your take on this?

[oleq]

I created a follow-up in #5892 so we can close this issue and get back to the problem later on.
