Installing 2017.12 and later will PERMANENTLY DELETE ALL V1 TEST DATA!
As per the announced roadmap, the LAVA software team are glad to announce the release of 2017.12 which marks the completion of the migration to V2 and the death of V1.
Upgrades normally try to avoid removal of data but this upgrade deliberately drops the V1 data tables, permanently. Whilst this procedure has been tested, there is no guarantee that all instances will manage the removal of the V1 test data cleanly. It is strongly recommended that all instances have a usable backup before proceeding.
At all costs, avoid running commands which activate or execute any further migration operation, especially lava-server manage migrate and lava-server manage makemigrations. Remember that removing, purging or reinstalling the lava-server package without fixing the database will not fix anything as it will attempt to run more migrations. Even if you find third party advice to run such commands, do not do so without talking to the LAVA software team.
It remains possible to escalate a failed upgrade into a complete data loss of V1 and V2 test data by trying to fix a broken system. In the event of a failed upgrade, the LAVA software team may advise you to restore from backup and then determine if there are additional steps which can be taken to allow the upgrade to complete, instead of attempting to fix the breakage directly. Without a backup, your only option may be to start again with a completely fresh installation with no previous test jobs, no users and no configured devices.
Moving to systemd
=================
2017.12 also completes the move to reliance on systemd only as PID 1 for lava-server and lava-dispatcher.
Next stages
===========
Python3
-------
The next large change is the move to Python3. lava-dispatcher continually passes the unit tests using Python3. With the removal of the V1 codebase, work can now start on moving lava-server to using Python3 ahead of the move to Django2 which drops support for Python2.
Stretch
-------
In the new year, the Linaro lab is due to move all machines to Debian 9 Stretch. At some point after that, the LAVA software team will drop support for Debian 8 Jessie.
