Hello,
I was asked by WMF to make the database views on Toolserver fit to their privacy policy they applied at Toollabs.
This means some data in the databases should not be displayed any longer.
It regards fields in the tables revision, logging, recentchanges, oldimage and filearchive.
Table entries that should be hidden will not be displayed by the Toolserver database servers.
These entries can be unhidden by the Steward level users of the Wikipedias and are then accessible again.
Some fields are not even shown in the default view because queries on these tables then no longer can use indexes which makes the
databases and queries run very slow.
I put alternative views in place in this case in case you need more fields you'll find slower views with most of the fields (but
redacted).
Please note that this may change the number of rows and other results of your tools.
If you have any issues with your tools because of this change please let me know.
Cheers
