As part of T30135: Review and deploy VipsScaler extension we added the option to set the comment of a thumbnail with the file descriptionpage url that it came from, as we did for the imagemagick scalar. It seems however that the option was never actually enabled in the configuration for the sites, and that we have been generating thumbnails without 'backtrack' urls ever since then...
That's not really what was intended.
This relates to the "setcomment" options of wgVipsOptions

Change 309505 had a related patch set uploaded (by Dereckson):
Install exiv2 to mediawiki::packages::multimedia
So the question is to know if we want to do this with exiv2, or if we want to update the VIPS extension code to support exiftool, already installed on multimedia servers.
@TheDJ Do you have an opinion about this?
@Dereckson right. I have no opinion on this. My ticket was only an observation about functionality that we lost compared to the pre-vips stages, and I have no specific preferences in how it gets resolved.
Change 309505 abandoned by Dereckson:
Install exiv2 to mediawiki::packages::multimedia
Reason:
No preference for this solution
To summarize, it was offered to solve right now the issue installing the missing software. This solution doesn't have any enthusiasm from the current extension maintainers.
An alternative solution offered is to improve the extension code to use exiftool, already deployed on the scalers, to perform this task.
It seems like thumbor has taken over thumbnailing, and it never sets the old jpg comment at all.
So i guess this could be closed?
I also don't know why we have VIPS installed at all in a post-thumbor world.
Closing, as i don't think there's much point anymore when we don't use vips to scale things.
