Bug Description

If we change a global-requirement in a non overlapping way... like

psutil < 1.0


psutil > 1.1

We cause a lot of failures in the gate.

The reason is that the requirements change is co-gating. So requirement enters gate.

Everything behind that requirement is told to use the new thing. It can't, it's not in the mirror, and only the requirements job is allowed to punch through the mirror.

Changes behind the requirements change will then fail, over and over again. Gate carnage will ensue. Until eventually the requirements change merges, triggers a mirror rebuild, and that then updates the mirror.

We should probably either prevent this in requirements, or we should come up with a way to let projects punch holes in the mirror if they are in a window where requirements change is going on.

message:"Could not find a version that satisfies the requirement psutil>1.1.0" AND filename:console.html

The following non-overlapping requirements change broke the gate because there is a small lag in the mirror job

This could be prevented with a fairly minor change to the requirements check job. Adding low-hanging-fruit tag accordingly.

    Checks if requirements overlap between head and branch reqs

    If there is a requirement in head and branches, and are not equal,
    check if the head requirement is overlapping with branch one,
    if not it triggers an error

This change actually ended up enforcing overlap on project-specific requirements changes rather than global requirements changes, spawning bug 1326504. It is being reverted, then we can regroup and look into inserting it into the right place.

I think the place to have it apply to the requirements repo is by adding a test script in openstack/requirements and then running it via tox from a new job (the skeleton would probably look like openstack-infra/config's config-compare-xml job which compares configuration between the parent commit and the proposed one).

    Remove requirements overlap check

    The requirements overlap check was originally designed to address
    a behavior introduced by our requirements-driven pypi mirror. Now
    that we use full mirrors of pypi, it is no longer necessary and
    is an artifical restriction that may cause problems for us.
