504048 - Implement update retries, backoffs and fuzzing

Status: RESOLVED WONTFIX

(Firefox :: Search, enhancement, P5)

Description

[Ryan Flint [:rflint] (ping via IRC for reviews)]

Currently if an engine update fails, it won't be attempted again until next scheduled update. We should retry failed updates after a certain amount of time, backing off exponentially if we're encountering server errors.
We should also fuzz scheduled updates (similar to what we do for app updates) to avoid having a bunch of clients hitting the update server at or near the same time.

Is this why http://www.mozilla.com/en-US/plugincheck/ shows i'm running a vulnerable Flash version but the built-in add-on update check says that everything's fine?

This is completely different and has nothing to do with updating search engines. The current version of the Add-ons Manager doesn't have a integrated plugin checker yet. So you are looking for bug 613305.

We already check every 6 hours, and most sites don't support OpenSearch updates, therefore I'm closing this as wontfix as it isn't worth implementing.
