810057 - Data Usage bar doesn't update in real-time, so it's hard to know how accurate it actually is

Status: RESOLVED FIXED

(Firefox OS Graveyard :: Gaia::System, defect)

Description

[Daniel Holbert [:dholbert]]

STR:
 1. Open Cost Control app, and go into its settings (gear icon), and set a small max data cap (e.g. 1 MB)
 2. Open browser.
 3. Drag down the status bar, to see what your current data usage is.
 4. Open some ~200 KB or larger file in the browser, e.g. http://tinyurl.com/8tcorqn
(which redirects to http://th05.deviantart.net/fs70/PRE/i/20

se_follow_me_by_sharpwriter-d5buwfu.jpg )
 5. After the file loads, drag down the status bar to look at your data usage.

ACTUAL RESULTS: Data usage hasn't changed.
EXPECTED RESULTS: data usage should have increased by 0.2 MB

If you wait a few minutes and then drag down the status bar, *then* the bar will have updated -- at least, it seems like it.

So it does eventually update, but there's a significant delay.

I'm working on this to update when the application is shown. I think it is a lack of the API, it could be great if we can attach a callback to an "event" saying: "each time XXX bytes are consumend, please, call me".

This should be fixed as refactor (bug #816927) already landed and now the data usage is updated every time the widget / application is shown. Resolving.
