Bug 111913 – [chromium] Helper Plugin does not have a URL for its Document

• Status: RESOLVED
• Resolution: FIXED
• Component: WebKit Misc.

[David Dorwin]

WebHelperPluginImpl creates a Document using DocumentWriter, but it does not provide a URL to begin(). As a result, the Document does not have a URL, meaning the browser cannot make decisions based on the host. Since the Helper Plugin is working on behalf or an element, it should have the same origin as the element.

Why do we pass in a hostFrame instead of a hostDocument?

Frames don't have URLs.  Documents have URLs.

These changes look spurious.

Thanks.

Any concerns about how |url| is used while creating the Document or during its lifetime? During creation, it seems to mostly be important whether it is a plugin (i.e. foo.swf), which is not the case here.

Done.

No reason really. Now, it's a const ref, which is nice.

Done.
