783855 - Migrated image/attachment all need a REDIRECT to be fetched

Status: RESOLVED WONTFIX

(Developer Documentation Graveyard :: General, defect, P3)

Description

[Jean-Yves Perrier [:teoli]]

All migrated images/attachments need a REDIRECT when used in a page.

E.g. on https://developer.mozilla.org/en-US/docs/CSS/linear-gradient there are 2 image links:
https://developer.mozilla.org/@api/deki/files/5961/=linear-gradient.png
https://developer.mozilla.org/@api/deki/files/3849/=lingradexample.png

both lead to a REDIRECT to the new URLs:
https://developer.mozilla.org/files/3537/linear-gradient.png
https://developer.mozilla.org/files/2843/lingradexample.png

This may lead up to 1.5s gain for pages with 1 to 8 attachment, more with pages with more attachments.

This is a upper limit as these REDIRECT are fetched in parallel with other requests.

We can edit these manually, but with have 1000s of these and the relation between old and new URLs is somewhere in the system as we perform a redirect.

I was wondering about speed of image loading in canvas docs and other areas as well recently, but those images often have the final url already, it seems.

Luke, can you or someone get us a list of pages that still use these old image links? (would do myself, I have no dump anymore)

Basically, docs (the rendered content/last revision) which have "@api/deki/files" in the content, so that we can see how many pages are affected and if this is a content-debt that is worth to fix.

Looks like we can get the list via the admin interface:

Closing; probably not actionable at this point.
