The current database upgrade instructions for Beaker 0.16 add the new power.power_quiescent_period column (which has a Python-level default of 5, but no SQL-level default) but they fail to set the value to 5 for existing rows in the table.
Need to add:
UPDATE power SET power_quiescent_period = 5;
*** Bug 1079603 has been marked as a duplicate of this bug. ***
The updated instructions are now in the branch-specific docs here:
The document is available on page https://beaker-project.org/docs-release-0.16/whats-new/upgrade-0.16.html
Beaker 0.16.1 has been released.
Existing installations of Beaker 0.16.0 may prefer to run a conditional version of the UPDATE statement, which will avoid overwriting any quiescent period settings which have already been changed from the incorrect default 0:
SET power_quiescent_period = 5
WHERE power_quiescent_period = 0;
