Hello list,
I have had a short attempt:
set GLOBAL read_only=true;
on the MySQL that runs my curriki and it kind of works.
A few exceptions are thrown at the beginning but otherwise it seems to render well.
The interest is that it could allow some of the web requests to be served by a database
that is a slave of the main database, in live synchronization with the master MySQL.
Has anyone tried that?
thanks in advance

You mean that the public wiki reads data from the read-only database,
which is actually updated by cloning another read-write database updated
from a private wiki? That's an interesting idea for securing a public
server.
You should also set in xwiki.cfg:
xwiki.readonly=1
This might reduce some of the errors that you get, although there's a
lot of code that ignores this setting. It would be nice if you could
report (on jira) what exactly breaks so that we can fix it properly.

could be though you need a filtering mechanism thn.
You should also set in xwiki.cfg:
xwiki.readonly=1
why *also* ?

If you say a lot of code ignores that than I'd better not rely on it I'm afraid.
Nonetheless, the previous option sounds good.

"Set" it so that some of the code inside the platform is aware that the
wiki is supposed to be read-only and act accordingly. "Also", because
that's not enough to guarantee that no changes will be made to the data,
and the database-level read-only is much safer.
