Not sure if trying to use an unhandled file type via InstantCommons makes sense; the image parameters in the wikitext and the image parameters in the URL (or imageinfo API or hypothetical linking API) don't necessarily use the same syntax; what would transform that? (Granted, you get similar problems when parameter transformation is handled by the local extension and there is a version mismatch between the local and remote installation.) Fetching all thumbnail URLs in a single request is T56037 <https://phabricator.wikimedia.org/T56037> and should not be particularly complicated. Fetching the thumbnails themselves, well, if you care about speed, you probably use hotlinking <https://phabricator.wikimedia.org/T114098#1717456> or a 404 handler anyway. > (Iframe embedding as a fallback for unknown handlers sounds possible, > could expose > a frame URL in the imageinfo data.) > In general that would be a nice idea (see T27854 <https://phabricator.wikimedia.org/T27854>). Specifically for embedding unknown file types in MediaWiki though, we would probably have to introduce some standard key-value syntax for image parameters first, instead of the current mess where it's parsed by an arbitrary set of regexes defined by the media handlers and generated in a similarly flexible way. And then you still have the problem of handling unknown media types in VisualEditor which would need some kind of parameter metadata at least. _______________________________________________ Wikitech-l mailing list [email protected] https://lists.wikimedia.org/mailman/listinfo/wikitech-l
