A fallback render drops the requested effect and is only a degraded
stand-in, so writing it to the 30 day disk cache kept serving the worse
image long after the local renderer recovered. Cache primary renders only
and let the next request pick up the real render.
Effect renders need a little over 4s, which the 4s primary timeout cut off,
so every avatar with the default effect fell through to an unreachable
public fallback and rendered as a placeholder. Raise the primary budget
above the observed render cost and shorten the fallback budget.
Also stop the proxy from stamping no-store over the avatar and media
responses, so browsers keep the long-lived Cache-Control the route already
sends, and recreate the imaging cache directories with the container user
on every deploy, since root ownership made those cache writes fail
silently.
- Add persistent disk cache for rendered avatars/badges (storage/imaging)
so repeats never touch the flaky local renderer and cached renders
survive upstream downtime
- Serve cache-first with stale-on-error; cut primary/fallback timeouts
from 10s/6s to 4s/4s so failing images cannot stall pages
- Avatar proxy now returns a graceful 200 silhouette instead of 502 when
no renderer can produce a figure, so no broken-image glyphs appear
- Badge endpoint becomes a caching proxy trying configured CDN, public
Habbo CDN and local /swf copy in order, and drops the fragile IP rate
limit that could blank badge streams
- Route all site badge images (profile, me, badges, apply pages) through
the cached proxy instead of hot-linking images.habbo.com
