XML sitemap URLs should not append a trailing slash

[jonoaldersonwp]

Requests to XML sitemap URLs, such as ​https://wordpress.org/themes/sitemap.xml, ​https://wordpress.org/themes/sitemap-index-1.xml, ​https://wordpress.org/plugins/sitemap-index-1.xml currently redirect and append a trailing slash.

This should not occur; the redirect should be removed/prevented.

AFAIK, we don't have any sitemaps on w.org.

There is a feature in Jetpack that can generate sitemaps, but that should be turned off on all the sites by default? It might have been on for some reason earlier, but appears to be off now.

Closing this since there isn't a sitemap, but if we decide to make one happen, then things like this should be considered in a more overarching ticket.

Replying to Otto42:

Jetpack Sitemaps were indeed enabled deliberately on a number of sites quite some time ago.

[jonoaldersonwp]

But they're disabled now, seemingly?
Can we (re)enable, and configure/fix them?

[bradleyt]

It should be noted that the (currently disabled) sitemap URLs are also being referenced in ​https://wordpress.org/robots.txt. Either the sitemaps need to be re-enabled, or the robots.txt should remove these references.

Looks like this only applies to the Theme Directory, not plugins?

For reference, this is primarily caused by this:

as mentioned in https://meta.trac.wordpress.org/ticket/4559#comment:9

Nudging this up, as it's increasingly important given the state of the themes directory.

[dd32]

In 9818:

Theme Directory: Don't trailing slash .xml files (Sitemaps).

See #5022.

In 9819:

Theme Directory: Skip outdated themes in the Jetpack Sitemaps.

Fixes #5022.
