Changes to bug heat


Hi Everyone,

The way in which bug heat is calculated and displayed in Launchpad, is
changing. From 6th February, bug heat will no longer age/degrade, and
the active flame counter symbol will be replaced by a number, next to
a static flame.

Bug heat ageing is the cause of a wide range of timeouts in Launchpad.
Every bug’s heat has to be recalculated and updated every day using a
series of complex calculations, and when there are around 1 million
bugs reports to track, that’s a lot of pressure on the system,
consuming a significant chunk of resources.  Turning off bug ageing is
the simplest way to solve this issue.

The flame counter symbol, although adding some visual flair (and
flare), also needs to update every time the bug age recalculations are
made.  The continual stream of updates to the bug rows also results in
poor search index performance.

We’ll still have a flame symbol, however it’ll be static, with the bug
heat number next to it. Although not as visually dynamic, it’ll be
easier to work out bug heat scores more exactly, at a glance.

Although I’m sure some of us will miss this little Launchpad feature,
fewer timeouts are good news for everyone. If you'd like to see a

My Best,
