`revisions` only showing the most recent 500 revs

[Michał Sawicz]

For a number of snaps I'm collaborator on, I'm only seeing the most recent 501 revisions:

$ for snap in multipass mir-kiosk subsurface mir-kiosk-apps; do
  REVS=$( snapcraft revisions $snap )
  echo === $snap: $( echo $REVS | wc -l ) total ===
  echo $REVS | tail -n5
done
=== multipass: 501 total ===

It is said that all revisions "live forever" on the snap store. But how do we access them?

[Daniel Manrique (roadmr)]

This sounds like a "snapcraft revisions" bug. The API returns 500-item pages (Maxi observed that the 501st line is a header from snapcraft revisions).

src/devportal/api/v1/handlers.py
MAX_REVISIONS_PER_PAGE = 500
and in src/devportal/api/v2/snaps.py MAX_RELEASES_PER_PAGE = 500

Then this would actually need snapcraft to notice there are more pages and request the following ones as well.

[Michał Sawicz (saviq)]

This actually seems like a different issue to what Chipaca has, and a snapcraft one at that, which seems to not paginate, and there's a hard 500 limit to a page.
