[PATCH] testbot: Allow explicitly specifying a Step's dependency.
Francois Gouget
fgouget at codeweavers.com
Sun Feb 25 18:40:25 CST 2018
This allows the TestBot to start running the 64 bit tests even if there
are still some 32 bit tests to run.
It also lets the TestBot more freely schedule the tasks when a job
involves many test units (and thus many steps).

This patch requires updating the database schema. So:
* Apply testbot/ddl/update31.sql
* Restart Engine.pl
* Restart the web server.
