Short description:

The current *_user_text fields are being replaced with nullable *_user_ip fields containing the user_ip only for anonymous users.  This first half of the schema update adds the *_user_ip fields.

Which wikis are affected:

test, test2, and mediawiki.  But the changes are only to tables 
on the extension1 cluster's flowdb.

Which tables:

flow_workflow
flow_revision
flow_tree_revision


What is the change to those tables:

ALTER TABLE /*_*/flow_workflow ADD workflow_user_ip varbinary(39) default null;
ALTER TABLE /*_*/flow_tree_revision ADD tree_orig_user_ip varbinary(39) default null;

ALTER TABLE /*_*/flow_revision
        ADD rev_user_ip varbinary(39) default null,
        ADD rev_mod_user_ip varbinary(39) default null,
        ADD rev_edit_user_ip varbinary(39) default null;

These new columns are not queried directly, only selected as part of other queries.   They are 39 bytes to hold either ipv4 or ipv6 addresses formatted as strings, same as they are displayed in the interface.  They are superseding the  current *_user_text fields which will be dropped from the table after migrations have run.
