Thanks Brian. It's great to get an email from Mr. Glance.

I managed to patch Devstack, and a first test was successful. Perfect!

A bit late, I then found numerous warnings in release notes and other documents that UWSGI should not be used when deploying Glance. My earlier web searches flew by these documents without noticing them.

Trying Glance's new import process, my images are all stuck in status

I can see that there are tasks for those images; they are pending. The
Glance API log doesn't contain anything that clues me in (debug logging
is enabled).

The source code is too involved for my feeble Python and OpenStack
Internals skills.

*How can I find out what blocks the tasks? *

This is a stable Rocky Devstack without any customization of the Glance
config.

The tasks engine Glance uses to facilitate the "new" (experimental in
Pike, current in Queens) image import process does not work when Glance
is deployed as a WSGI application using uWSGI [0]; as you observed, the
tasks remain stuck in 'pending'.  You can apply this patch [1] to your
devstack Glance and restart devstack@g-api and image import should work
without additional glance api-changes (the patch applied cleanly last
time I checked, which was a Stein-1 milestone devstack; it should apply
cleanly to your stable Rocky devstack).  You may also want to take a
look at the Glance admin guide [2] to see what configuration options are
available.
