Subject [jira] [Created] (CB-1388) Add reset() to plugin API and fix callback collisions on all platforms
Date Fri, 07 Sep 2012 14:10:07 GMT
Braden Shepherdson created CB-1388:

             Summary: Add reset() to plugin API and fix callback collisions on all platforms
                 Key: CB-1388
             Project: Apache Cordova
          Issue Type: Bug
          Components: Android, Bada, BlackBerry, CordovaJS, iOS, Qt, Tizen, webOS, Windows
8, WP7
    Affects Versions: 2.0.0
            Reporter: Braden Shepherdson
            Assignee: Braden Shepherdson
             Fix For: 2.2.0

There are three parts to this bug.

First, platform-specific: we should add a reset() function to the plugin API which is called
on top-level navigation or refresh, so that plugins can know to cancel any long-running requests
and reinitialize themselves. This won't be relevant to some platforms 

Second, platform-independent: the callback IDs generated on the Javascript side should be
randomized in some way to prevent collisions after navigation. Otherwise a request might get
the ID "Service1", and before it has a chance to complete we navigate and a new request is
made, also receiving "Service1". Then the first response comes back and the new Service1 callback
is handed the old results.

Third, we should add a test for this to Mobile Spec, if possible. This is a tricky thing to
reproduce reliably, unfortunately.

I'll tackle the second and third parts, and Android for the first part. It would be great
if people who work on other platforms would add the reset() logic, or close the platform bugs
if the platform is all-Javascript and fully reloaded on navigation.
