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.
* [IMP] module_auto_update: Create new module
* Add checksum_dir and checksum_installed fields to ir.module.module
* Add checksum_dir to compute current checksum of module directory
in addons path
* Add checksum_installed to store checksum of module directory
when module was last installed or upgraded
* Use checksumdir Python library to compute module directory sha1
hashes, ignoring pyc and pyo extensions
* Extend update_list method to compare modules' checksum_dir and
checksum_installed, then change state of modules with differing
checksums to 'to upgrade'
* Replace Apps/Updates menu item with menu item of same name, which
updates apps list and displays tree view of ir.module.module
records with state 'to upgrade'
* Extend create and write methods to store computed checksum_dir as
checksum_installed during module installation and upgrade, and
set checksum_installed to False on uninstall
* Use context to stop checksum_installed from being updated during
upgrade/uninstall cancellation
* Add cron job to periodically check for module upgrades by
comparing checksums, then perform any available upgrades
* Extend upgrade_module method (called by cron and 'Apply Scheduled
Upgrades' menu item) to call update_list
* Add post_init_hook to store checksum_installed of existing
modules
* Add test coverage
* [FIX] module_auto_update: Fix test broken by changes
* Use dummy module to test update_list method instead of
module_auto_update
