I just updated to the stable dogfood build that went up this morning, Build ID 20121127132302.

Using that build, I just did "check for updates".

That added the "Checking for updates..." text below the button, like usual, but now that text never goes away. (It doesn't tell me whether there's an update available or not.)

Additionally, my logcat output contains:

Sorry for the late response, I think :marshall_law can help answering this question.

:marshall_law, looks like we get 404 while retrieving update.xml, which results the exception on nsIPromptFactory.getPrompt(). Do you know more details about this exception?
Flags: needinfo?(schien) → needinfo?(marshall)
Is this a Gaia bug that Settings app doesn't handle the error response, or a Gecko bug that DOM API doesn't return the error response?

We need an assignee and clarification here.

The 404 exception is expected when a new update hasn't been posted yet (this error is meant to be swallowed in our current setup).
Flags: needinfo?(marshall)
FWIW, this is currently WORKSFORME -- "checking for updates..." is replaced with "This is already the latest version of Firefox OS" after a few seconds.

That might be because the update URL is _not_ currently a 404, though.  (In logcat, it looks like we successfully download update.xml, and then it says "AUS:SVC UpdateService:selectUpdate - skipping update because the update's application version is less than the current application version" and then "UpdatePrompt: Setting gecko.updateStatus: already-latest-version").

So, we may still suffer from the symptoms described in comment 0 when the update URL *is* a 404 (e.g. from network issues or server downtime).  If so, we should still be sure to handle that gracefully.
I took a look of the code logic in Settings app, Gaia should be notified if one of the following cases happened:
 * - no-updates
 * - already-latest-version
 * - check-complete
 * - retry-when-online
As my understand, the update URL is specified in Gecko, so Gaia can do nothing but represents the fact either *no update* or *update failed*. I guess Gecko needs to handle 404 URL case, and report correct error in this case.

Assign to Steve for testing and tracking this issue.

I used build 20121213110234 and test two cases. Corresponding logs are as the following:

Network (WiFi) turning off:
E/GeckoConsole( 802): AUS:SVC getStatusTextFromCode - transfer error: Update server not found (check your internet connection), code: 2152398878

Network (WiFi) turning on but failing to connect to the internet:
E/GeckoConsole( 802): AUS:SVC getStatusTextFromCode - transfer error: Network is offline (go online), code: 2152398864

In the first case Gecko triggers a property change of "gecko.updateStatus" with value "retry-when-online". In the second one nothing happens, thus Gaia is unable to handle the error. 

Marshall, Any suggestion on this?

IMO, a 404 should reply with the "no-updates" status, since that is what the HTTP response code actually means. Does anyone object to me fixing platform this way?

Hrm, that's a surprising result. How quickly are you turning off / on the wifi? After wifi is off, is your device still using cellular data?

The "retry-when-online" status should only happen when the network is offline. AFAIK the network online/offline status doesn't actually check for an external "internet" connection -- this is just a simple check of (wifi_connected || cell_data_connected).

I think this will just set the error code to the HTTP error code, I'd prefer to set this to an error cod defined up top like for example CERT_ATTR_CHECK_FAILED_HAS_UPDATE.  Especially since some HTTP status codes could conflict with the previous values.

If I understand correctly this._getChannelStatus can return either an HTTP status code or an nsresult status.  Yuck, but not your code.  I'm not sure what you're be using the errorCode for internally but it may be possible for _getChannelStatus to return a value which is within the range of HTTP status codes.  I'll leave it up to you if you want to try to fix that now by changing _getChannelStatus.  If so I think that function should be split into 2.

actually on second thought if the function does return both status codes and nsresults (which I think it does) then I think it's best to fix it now.

I'm not sure I fully understand how you want to fix this function -- should I just move the http range / offset logic into _getChannelStatus?

Splitting the function up seems like it might cause more headaches than it's worth, since Firefox error strings are localized based on both HTTP and nsresult error codes:

https://mxr.mozilla.org/mozilla-central/source/toolkit/locales/en-US/chrome/mozapps/update/updates.properties#100
Inside _getChannelStatus, I think that:
 var status = 0;
    try {
      status = request.status; <<---- returns http status code
    }
    catch (e) {
    }

    if (status == 0)
      status = request.channel.QueryInterface(Ci.nsIRequest).status; <<---- returns nsresult
    return status;

Can you verify that is the case? I think it is.
What I'm suggesting is to make a _getChannelHTTPStatus and a _getChannelNSResult function which does each part respectively and delete _getChannelStatus.
You'd replace the existing calls of _getChannelStatus with calls to _getChannelHTTPStatus, but if that fails then you'd call _getChannelNSResult.  If the call to _getChannelHTTPStatus succeeded then you'd set the errorCode at that time.

I'm not sure I fully understand what you mean about the localization please expand if you think it's still a problem with my clarification.

Seems this won't be needed because nsresults will never contain a code in the HTTP status code range.  So this is r+.

you just need _('check-error'); the 3rd parameter is for fallback

I'd prefer something like :

if (value !== 'check-complete') {
  systemStatus.textContent = _(value) || _('check-error');
  console.info('Error during system update, code is', value);
}

So that we always have a generic catch-all error, but still output the real error code to the console.
