Database Changes to OpenGroupware v5.5

For those building from trunk, or currently pulling packages from OBS, there is a new table required as of r2256.

CREATE TABLE ctags (
entity VARCHAR NOT NULL,
ctag INTEGER NOT NULL DEFAULT 0
);
INSERT INTO ctags (entity) VALUES ('Person');
INSERT INTO ctags (entity) VALUES ('Enterprise');
INSERT INTO ctags (entity) VALUES ('Date');
INSERT INTO ctags (entity) VALUES ('Job');
INSERT INTO ctags (entity) VALUES ('Team');

This is part of adding ctag support to OGo (specifically ZideStore). ctags allow a client to *very* quickly detect if the contents of a collection have changed; such as the /public/Contacts folder. Thus avoiding doing a PROPFIND on the entire folder to determine if a re-sync is needing. ctag support is not complete or working yet, but without this table a server post-r2256 will fails some operations with a database error.

The subversion repository contains an update script for migrating a v5.4 database to v5.5.
