The previous implementation of this addon proved being extremely buggy:
- It supplied out of the box a enabled cron to update Odoo that didn't restart the server, which possibly meant that upgrades broke things.
- It overloaded standard Odoo upgrade methods that made i.e. installing an addon sometimes forced to upgrade all other addons in the database.
- The checksum system wasn't smart enough, and some files that didn't need a module upgrade triggered the upgrade.
- It was based on a dirhash library that was untested.
- Some updates were not detected properly.
- Storing a column into `ir.module.module` sometimes forbids uninstalling the addon.
Thanks to Stéphane Bidoul (ACSONE), now we have new methods to perform the same work in a safer and more stable way.
All I'm doing here is:
- Cron is disabled by default.
- Installed checksums are no longer saved at first install.
- Old installations should keep most functionality intact thanks to the migration script.
- Drop some duplicated tests.
- Allow module uninstallation by pre-removing the fields from ir.mode.model.
- When uninstalling the addon, the deprecated features will get removed for next installs always.
Besides that, fixes for the new implementation too:
- When uninstalling the addon, we remove the stored checksum data, so further installations work as if the addon was installed from scratch.
