Moin Wiki

I'm still in the process of updating my web server machine from Fedora 25 (now EOL) to Fedora 27. One of the things I noticed that wasn't working was search on this wiki, which was failing with this error:

FeatureUnavailableError: Flint backend no longer supported

It seems the update to the underlying Xapian search library rendered my existing index obsolete. The fix was to rebuild the index: 

# runuser -s /bin/sh -c "moin --config-dir=/srv/www/tips/cgi-bin --wiki-url=http://www.city-fan.org/tips/ index build --mode=buildnewindex" apache
# systemctl stop httpd
# runuser -s /bin/sh -c "moin --config-dir=/srv/www/tips/cgi-bin --wiki-url=http://www.city-fan.org/tips/ index build --mode=usenewindex" apache
# systemctl start httpd
