For about half a year I have been using the Mozilla Weave Sync plug-in to synchronize the Firefox data from various systems with my own Weave server. Updating the plug-in during this time has been no problem at all, except getting used to the repeated complete UI overhauls.

Keeping the server component updated, or even knowing when such an updated was required by a new version of the plug-in was not quite as easy.  After my recent upgrade to the first beta release 1.0b1 of the plug-in, the sync process failed again, indicating that an upgrade of the server might be needed.

On the server side, the directory and URL layout has been changed, making it somewhat clearer now.  I gathered the necessary changes from the Mozilla Labs wiki, from the pages describing the setup of the sync and user service.

The sync would still not work at this point, but now I could see why in the server’s error log:  for the MySQL table users, the column username no longer was the primary key. Instead, the developers added a synthetic primary key id to the table. Simply dropping the old key and creating the new one helped to get my weave server up and running again:

ALTER TABLE users DROP PRIMARY KEY;
ALTER TABLE users ADD COLUMN id int(11) NOT NULL PRIMARY KEY auto_increment;
