Bug 41651 – REGRESSION (Safari 4 - Safari 5): Plugin embedded into an IFRAME doesn't work due to dynamic global object not having a RootObject

• Status: RESOLVED
• Resolution: WONTFIX
• Component: WebCore JavaScript

[verney]

Hello ,

We are developping a Web plugin (using the Webkit API, not the NPAPI) and noticed a major regression related to scriptable plugin in Safari 5 and we have reproduced the issue on the latest Webkit version:

Case 0 : If the plugin is embedded in a simple HTML page, it works perfectly.

Case 1 : If the plugin, is embedded INSIDE and IFRAME, the method gets called correctly from Javascript but when the plugin tries to call a JS function using callWebScriptMethod, then the whole Webket crashes (see report at the end of the mail). This happends everytime.

Case 2 : If my plugin embedded inside an IFRAME which is itself included inside another IFRAME, the plugin gets 'nil' arguments when one of its methods is called by JS.

This happends on OS 10.6 with Webkit 2 / 6533.16, r62241, running in 32 bits compatibility mode as well as with Safari 5.

The same plugin and same HTML pages work fine when running under Mac OS 10.5 with Safari 4.0.4.

Is it a webkit bug? We need to release our Web plugin but this is blocking and for obvious reasons we are unable to modify the page  structures of existing Web sites that are using our plugin to remove all the IFRAMES. How can we correct this?

Here is the code I use to obtain the scripting object :

- (void) initView
{
    if( viewPanel != nil )
    {
        [self setFrame:[viewPanel frame]]; /* adjust the frame from your nib's view to the plug-in's view */
        [self addSubview:viewPanel]; /* add the view from the nib as our one and only sub-view */
    }

    pluginContainer = [pluginArguments objectForKey:WebPlugInContainerKey];
    WebFrame * containerFr = [pluginContainer webFrame];
    m_myWebView = [ containerFr webView ];
    WebFrame * main = [ m_myWebView mainFrame ];
    // Find Iframe of plugin
    // The callback are in the same Iframe of plugin
    if ( main != nil )
    {
        m_mainFrameView = [ main webView ];
    }
    else
    {
        PLG_TRACE(LOG_NOTICE, "No main frame found. Assuming that we are in the main frame.");
        m_mainFrameView = m_myWebView;
    }
 
    NSString* name = [containerFr name];       
    @try
    {
        if ( name != nil && [name length] > 0)
        {
            PLG_TRACE(LOG_DEBUG,"ScriptableObject : Plugin on IFRAME %s",ID_2_CHAR(name));
            NSMutableArray * chaineFrames = [ NSMutableArray arrayWithObject:name ];
            WebFrame * fr = [containerFr parentFrame];
            while (fr != nil && [[fr name] length] > 0)
            {
                [chaineFrames insertObject:[fr name] atIndex:0];
                fr = [fr parentFrame];
            }
            // Get scriptableObject
            m_scriptBridge = [m_myWebView windowScriptObject];
            // travel the tree to find the Iframe of plugin
            for (unsigned int i=0; i < [chaineFrames count]; i++)
            {
                PLG_TRACE(LOG_DEBUG,"Scripteur for frame %s",ID_2_CHAR( [chaineFrames objectAtIndex:i ] ));
                m_scriptBridge = [ m_scriptBridge valueForKey:[chaineFrames objectAtIndex:i ]];
            }
        }
        else
        {
            m_scriptBridge = [m_myWebView windowScriptObject] ;
        }
    }
    @catch (id e)
    {
        PLG_TRACE(LOG_ERROR,"EXCEPTION: %s --- defaulting on window level scripting object",ID_2_CHAR(e) );
        m_scriptBridge = [m_myWebView windowScriptObject];
    }
}

Here is the code executed when trying to call the JS callback function


- (void) FireEvent :( NSString *) callback :( NSArray *) arg
{
    if (m_scriptBridge)
    {
        @try
        {   
            PLG_TRACE(LOG_NOTICE,"send message to JS : %s [%s]",[callback UTF8String],ID_2_CHAR(arg) );
            [m_scriptBridge callWebScriptMethod: callback withArguments:arg];
        }
        @catch (id e)
        {
            PLG_TRACE(LOG_ERROR,"EXCEPTION: %s ",ID_2_CHAR(e));
        }      
    }
    else
    {
        PLG_TRACE(LOG_ERROR,"No scripting object initialized for callbacks.");
    } }


Have attach the crash report related to the case 1.

[Mark Rowe (bdash)]

In order to investigate this we need a way to reproduce this.  Can you please attach the source for a simple plug-in, along with any HTML page, that is required to reproduce the crash you describe?

[verney]

Hi Mark ,

Ok i make a simple plug-in , and test pages as soon as possible .

Thank you ,
Philippe

[verney]

We have now built a test plugin and simple test pages to reproduce and isolate the bugs:

- testPlugin.html is the page that embed the plugin itself. It has three buttons 
   - one to call a method StartPlugin()
   - one to set a property DialDomain
   - one to read the property and display the value in an alert box.

- testPlugin1frame.html: this page includes the former page inside an IFRAME. It has also three buttons
  - one to call the mthod StartPlugin by calling a JS function defined inside the child IFRAME
  - one to call the method StartPlugin by calling it directly from inside the page
  - one method to set the DialDomain property by calling a JS function defined inside the child IFRAME

- testPlugin2frame.html the page includes testPlugin1frame.html insde an IFRAME to create a second level of IFRAME embedding.

TestPlugin.zip is the source code of the test plugin. YOu'll have to compile it with XCode and copy the plugin directory into /USers/yourusername/Library/Internet-Plugins to activate it. It sends traces to the system console messages

Here are the situation where the plugin work

1/ load testPlugin.html in Webkit browser

- call StartPlugin(): method called ok. argument ok, callback is raised corrrectly
- set property: ok. data received correctly
- read propery: ok

2/ load testPlugin1frame.html in Webkit browser

- call StartPlugin() from inside the IFRAME: method called ok. argument ok, callback is raised corrrectly
- set property from inside the IFRAME: ok. data received correctly
- read propery from inside the IFRAME : ok

- call StartPlugin from parent page using function defined in child: ok
- call StartPlugin from parent page acessing plugin directly from paren: ok
- call set property from parent page using function defined in child: ok

Now Here is how to reproduce the bugs

LOAD testPlugin2frame.html

- call StartPlugin from parent page using function defined in child: NOK. Data received is NULL and callback is not executed 

- call StartPlugin from parent page acessing plugin directly from parent: Data received is NULL and callback is not executed 

- call set property from parent page using function defined in child: NOT data received is null.

Please advise

[Alexey Proskuryakov]

We fail to create a RootObject for the middle frame, so convertValueToObjcObject() cannot find one, and bails out.

The top frame has a RootObject because DocumentWriter::begin() creates it, and the plug-in frame has it thanks to runtimeObjectCustomGetOwnPropertySlot() asks HTMLPlugInElement to create it. But nothing creates a RootObject for the middle frame.

This sounds like it should affect NPAPI plug-ins, too.

[Alexey Proskuryakov]

Yes, this affects NPAPI plug-ins, at least in 32 bit.

work in progress

This contains a regression test for NPAPI plug-ins, and a fix for those. But then I went to fix WebKit plug-ins, and saw separate notions of root object and "origin root object" in relevant functions, and got confused. I may take another look some time later.

On an unrelated note, please be advised that WebKit plug-ins are not recommended - they won't work with WebKit2 multiprocess model.

So what is recommended? NPAPI?

When do you believe that a fix will be available?

I have been looking to NPAPI on Mac to follow your advise but we are facing a huge blocking problem:

- on Windows, the NPAPI provides an HWND form where we can build the user interface of our plgin
- on Mac OS X it seems that it is impossible to obtain an NSView as for Webkit plugins.

If you have a safe method of obtaining an NSView using NPAPI please advise.

In the meantime, if you could fix Webkit this would be great because the rollout of Safari 5 has introduced this regression on our services which were working fine on Safari 4

Plug-ins can run in a separate process, and there is no NSView provided automatically. You can find plug-in sample code in <http://trac.webkit.org/browser/trunk/WebKitExamplePlugins>, and with a quick web search, I found this discussion: <http://cocoadev.com/forums/comments.php?DiscussionID=1577>.

Let's not discuss NPAPI plug-in writing here any further. You can e-mail webkit-help <http://webkit.org/contact.html> if you need further assistance, or you can get help from Apple directly via DTS <http://developer.apple.com/programs/mac/support.html>.

> In the meantime, if you could fix Webkit this would be great because the rollout of Safari 5 has introduced this regression on our services which were working fine on Safari 4

Apple doesn't discuss future products, so I can't comment on whether or when this will be fixed in Safari.

If you can update the affected Web pages, then there is an easy workaround - just make sure that every frame has had some JavaScript activity. An empty onload handler would do.

Ok sorry. Thanks for the links and all the info.

Make sense but if this is fixed in Webkit, we have a chance that it will be fixed in the future on Safari.

> If you can update the affected Web pages, then there is an easy workaround - just make sure that every frame has had some JavaScript activity. An empty onload handler would do.

Mmmm interesting... But, in our "real" pages, it seems that we have Js in every frames and the issue is still happening.

Also, I am not sure that this would fix the issue that causes javascript functions not to be called from inside the plugin an dor services relay heavily on those.

We are more in the process of eliminating one level of I-FRAME to get back to a working condition.

NPAPI support is removed from Safari 14 onward and it is not supported in Webkit Builds like WebkitGTK as well. I think this can be marked as "RESOLVED WONTFIX". Thanks!

Further, WebkitAPI for plugin is also not supported in Webkit2. Unless if it is supported till today for Legacy Webkit or any other iOS webkit views then my comment can be ignored.

Additionally, from the patch the change (partial fix) was in one of this NP_jsobject.cpp file, which was removed based on below commit:

https://github.com/WebKit/WebKit/commit/043ef2367e62a2cc7e9facb1bdc42b0867b8dd6d

I think this can be "WONTFIX". Thanks!
