Re: Moving FirefoxOS into Tier 3 support

[Shawn Huang]

Hi Fabrice,
Following this comment, I'm confused. Do we need to check-in into
b2g-inbound by hand? "checked-in" keyboard no longer supports FirefoxOS
project? Does this mean only people who have Level 3 access permission can
land code?


https://bugzilla.mozilla.org/show_bug.cgi?id=1201778#c102

"dropping the checkin needed keyword here, alphan with the new tier 3
change for b2g and the drop of sheriff support for tier 3 we do not do
checkin needed anymore for b2g-inbound - if this needs to land on
mozilla-central let me know"

Intent to ship: Storage API estimate method

[Shawn Huang]

Summary:
​The Storage Standard defines an API for persistent storage and quota
estimates.
​The estimate()
 method can
be used to determine whether there is enough space left to download,
estimate() method returns both usage and quota per a origin.


Bug:
​​ 
​https://bugzilla.mozilla.org/show_bug.cgi?id=1267941​


Link to standard:

​https://storage.spec.whatwg.org/#dom-storagemanager-estimate


Platform coverage: all platforms.

Estimated or target release: 51

Preference behind which this will be implemented: Not needed.

DevTools bug: Not needed?


​Because ​Storage API needs to have SecureContext support, but currently
not having isSecureContext available in Workers (bug 1269052) is
problematic. Can we initially release the Storage API without Worker
support?

Re: Leakage of amount of storage used

[Shawn Huang]

I wondered that it's easy to find the identity by collecting how much space
all other origins take up together. It's possible that the size of other
origins that user has visited could change next time. Unless users don't
browse other sites. Maybe I missed something?
