766281 - ContentPermissionPrompt handleExistingPermission - handle null URIs

Status: RESOLVED INCOMPLETE

(Core :: DOM: Device Interfaces, defect)

Description

[Doug Turner (:dougt)]

gaia wants to use device APIs from chrome.  We don't have a URI for the document that is running that code and see this assertion:

[12:45:04] E/GeckoConsole(  116): [JavaScript Error: "[Exception... "Component returned failure code: 0x80004003 (NS_ERROR_INVALID_POINTER) [nsIPermissionManager.testExactPermission]"  nsresult: "0x80004003 (NS_ERROR_INVALID_POINTER)"  location: "JS frame :: jar:file:///system/b2g/omni.ja!/components/ContentPermissionPrompt.js :: handleExistingPermission :: line 18"  data: no]"


We grab the uri from the document like this:

http://mxr.mozilla.org/mozilla-central/search?string=+//+Grab+the+uri+of+the+document


Maybe there is a better way to grab the document's uri for chrome -- or maybe we should just check to see if the request has a uri before using it.

This bug is blocking our ability to take screenshots (Home+Sleep) from Gaia.

If this is hard or unlikely to be fixed soon, please let me know so I can revert Gaia back to its crappy content-only screenshots, which are at least better than nothing.

If https://bugzilla.mozilla.org/show_bug.cgi?id=768701 lands, then I don't need this bug fixed for Gaia system screenshots.

FxOS has been removed, we can refile this if we need chrome access to APIs that need permission.
