Redirect status

[rsbivand]

It is of course best to link to the site using for example https://grass.osgeo.org/grass-stable/manuals/variables.html, where grass-stable redirects to the current stable release. However, redirection is given as permanent:

$ curl -o - -I https://grass.osgeo.org/grass-stable/manuals/variables.html
HTTP/1.1 301 Moved Permanently
Server: nginx/1.18.0 (Ubuntu)
Date: Fri, 17 Mar 2023 19:28:48 GMT
Content-Type: text/html; charset=iso-8859-1
Connection: keep-alive
Location: https://grass.osgeo.org/grass82/manuals/variables.html
Front-End-Https: on

In CRAN/R, permanent redirection is not permitted in URLs in package documentation, so the current release (now grass82) has to be hard-coded. Could the server-side redirection infrastructure reply 307 instead of 301? Then rgrass could use grass-stable, not grass82, which means that the maintainer would avoid havng to update the GRASS version number each time it changes.

Likely yes, I'll look into this.

I have updated the related config lines to:

## latest "stable" redirect:
# Jun 2022 grass-stable -> grass82
    Redirect 307 /grass-stable/ https://grass.osgeo.org/grass82/
## latest "devel" redirect:
# Jun 2022 grass-devel -> grass83
    Redirect 307 /grass-devel/ https://grass.osgeo.org/grass83/
## latest "legacy" redirect:
# Oct 2022 grass-legacy -> grass78
    Redirect 307 /grass-legacy/ https://grass.osgeo.org/grass78/

Does this now work for you?

[rsbivand]

Yes, now:

$ curl -o - -I https://grass.osgeo.org/grass-stable/manuals/variables.html
HTTP/1.1 307 Temporary Redirect
Server: nginx/1.18.0 (Ubuntu)
Date: Sat, 18 Mar 2023 12:10:46 GMT
Content-Type: text/html; charset=iso-8859-1
Connection: keep-alive
Location: https://grass.osgeo.org/grass82/manuals/variables.html
Front-End-Https: on

The warning on CRAN checking is gone too, as expected. Thanks!
