Official spec links to non-official w3c.github.io

[Loirooriol]

AFAIK the w3c.github.io mirror is not official.
So why does the official https://drafts.csswg.org/css-backgrounds-3/#border-width have a link to https://w3c.github.io/csswg-drafts/css-values-4/#snap-a-length-as-a-border-width instead of https://drafts.csswg.org/css-values-4/#snap-a-length-as-a-border-width ?

Not sure if this is specific of css-backgrounds or if other specs are affected too.

I wonder if we should try to avoid absolute links all together, and instead prefer relative ones (either /css-values-4/@snap-a-length-as-a-border-width or ../css-values-4/@snap-a-length-as-a-border-width)

I don't see how you can construct a relative cross-spec link that works across all of the base URLs:

• https://www.w3.org/TR/2023/CRD-css-backgrounds-3-20230214/
• https://www.w3.org/TR/css-backgrounds-3/
• https://drafts.csswg.org/css-backgrounds/

The "snapped as a border width" is an autolink, so the URL is coming from the Reffy db. However, I just did a bikeshed update, and get:

╰╴bikeshed refs --text="snap as a border width"
text:      snap as a border width
type:      dfn
spec:      css-values-4
shortname: css-values
level:     4
status:    current
url:       https://drafts.csswg.org/css-values-4/#snap-a-length-as-a-border-width
export:    True
normative: True
for_:      []
==========
text:      snap as a border width
type:      dfn
spec:      css-values-4
shortname: css-values
level:     4
status:    snapshot
url:       https://www.w3.org/TR/css-values-4/#snap-a-length-as-a-border-width
export:    True
normative: True
for_:      []

So the db looks good. And there's nothing locally overriding that either. And I don't see these URLs ever appearing in https://github.com/w3c/webref/commits/main/ed/dfns/css-values-4.json. So I have absolutely no idea how it's showing that URL.

There's a search-and-replace on the github mirror CI that changes links from drafts.csswg.org to csswg-drafts.github.io, but that obviously shouldn't affect anything built by the drafts server.

There's a search-and-replace on the github mirror CI that changes links from drafts.csswg.org to csswg-drafts.github.io, but that obviously shouldn't affect anything built by the drafts server.

The draft server is currently proxying the github mirror for the actual drafts, so it's not serving anything it builds itself.

I recommend the search and replace on the github CI be removed. Nothing should be using public facing csswg-drafts.github.io links anymore.

[tabatkins]

Oh, I didn't realize that had been completed! Okay, yeah, I can make the change. I'll add in the script to auto-redirect if you visit the github.io site, too.

[tabatkins]

And done. The CI build no longer replaces links, and it automatically inserts a redirect script that detects if the url is on github.io, redirecting to the drafts server. The root page also redirects to the drafts server listing.

Hm, I just realized that all the redirects that caught the unversioned links are broken now, tho. I'll restore them.

[tabatkins]

Actually, ehhhhh, it'd be a bunch of trouble. I won't bother unless there's an obvious need.
