704300 - Compatibility update not applied for default-to-compatible addon's that don't meet min compat version in install.rdf

Status: RESOLVED DUPLICATE of bug 527141

(Toolkit :: Add-ons Manager, defect, P1)

Description

If an addon on AMO has in it's install.rdf a maxVersion of 3.7, it's not compatible even with strictCompatibility disabled, since 3.7 is less than the minimum compatible version. However, if AMO declares the maxVersion is actually higher than the minimum compatible version, then the add-on should get the compatibility update and it should be compatible.

If you try to install such an addon, it currently fails - claiming incompatibility. Sounds like the compatibility update isn't getting applied.

Example: https://addons.mozilla.org/en-US/firefox/addon/element-properties/
install.rdf maxVersion: 3.7a1pre
AMO maxVersion: 10.0a1

Looks like this is due to AMO not returning any updates, which means no updated compatibility info is sent either.

So, basically, due to bug 698355 not going live yet. I checked that theory with the same request going to the development site, which does return an update.

Will leave this open until bug 698355 goes live, to make sure this gets verified.

Nope, it's also due to my misunderstanding of compatibility updates - I had assumed they always get applied, but it turns out they only get applied when AddonUpdateChecker thinks they make a difference. So it's a bug in my patch for bug 527141.
