           Summary: wantsAllStreams always returning false, preventing
                    data pass-through for 500 server errors
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh Intel
        OS/Version: Mac OS X 10.7
            Status: UNCONFIRMED
          Severity: Major
          Priority: P2
         Component: Plug-ins
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: harningt at gmail.com


Similar issue with Firefox that was resolved: https://bugzilla.mozilla.org/show_bug.cgi?id=660989

NPPVpluginWantsAllNetworkStreams is a required item for our plugin in dealing with web service request errors since they return 500 status codes.

Visible in trunk/Source/WebKit/mac/Plugins/Hosted/HostedNetscapePluginStream.mm line 200 is code that always returns false for HostedNetscapePluginStream::wantsAllStreams() and it is marked "TODO".

I couldn't find any other hosted plugin streams browsing through Trac, however I'm guessing this is probably affecting other items.  Currently in progress is the massive checkout to see if this is present in other builds.


Reproducible: Always

Steps to Reproduce:
1. Setup an NPAPI plugin that handled NPP_GetValue return returns 'true' for NPPVpluginWantsAllNetworkStreams in the correct manner (or sets it using NPN_SetValue)
2. Ensure OOPP is enabled for the NPAPI plugin in question
3. Perform a web request known to return a non-200 result with NPP_GetURLNotify or NPP_PostURLNotify


Actual Results:  
1) No callback to NPP_GetValue for NPPVpluginWantsAllNetworkStreams.
2) A URLNotify callback with failure and no additional data

Expected Results:  
1) A callback to NPP_GetValue for NPPVpluginWantsAllNetworkStreams of not set already.
2) A full web request response with headers and data


This bug strongly affects software that we are trying to deploy.
