493815 - Preferences.js module should transparently save fractional numbers

Status: RESOLVED INVALID

(Cloud Services :: General, defect)

Description

[Dan Mills [:thunder]]

The prefs API doesn't support fractional numbers, they get rounded down to an integer.  Preferences.js prints a warning in this case, but ideally we should have an API that can transparently save fractional numbers.

It's possible to do right now by using the site-specific prefs API, which takes an nsIVariant, and can therefore correctly save/restore pretty much anything, but this is at the cost of not using the regular prefs API (so it's an interop cost).

Myk, any idea where this should be filed?  It's not Weave.

I suppose it should go to the jsmodules project bug tracker:

https://www.mozdev.org/bugs/enter_bug.cgi?product=jsmodules

I have filed it there:

https://www.mozdev.org/bugs/show_bug.cgi?id=21060

I'm not sure how it should be resolved here, though.  Incomplete?  Or maybe it should stay open as a "Weave should update Preferences.js once that module implements this capability" bug?
