[WPE][GTK] Add WebKitWebPage::did-associate-form-controls-for-frame and deprecate original did-associate-form-controls

• Component: WebKitGTK
• Status: RESOLVED FIXED

[Michael Catanzaro]

WebKitWebPage::did-associate-form-controls should provide a WebKitFrame argument so that Epiphany can run JS in the frame the form exists in rather than only the main frame. But we can't do that without breaking API, so add a new signal instead and deprecate the old one.

Note this needs a WK2 owner.

[Michael Catanzaro]

Note the point of deprecating is to remind us to get rid of did-associate-form-controls-for-frame and add the parameter to did-associate-form-controls next time we break API (e.g. for GTK 4).

WK2 owner approval for the cross-platform bits would be great.

What prevents m_frame from being null here?

If didAssociateFormControlsForFrame is implemented, we probably do not want to call didAssociateFormControls.

It's guaranteed by:

Page* Document::page() const
{
    return m_frame ? m_frame->page() : nullptr;
}

so I preferred to write it out as an ASSERT, rather than add an unneeded conditional or leave it ambiguous whether a conditional was missed here.

I'm not sure what advantage that would have, but either way seems reasonable to me, so OK.

This check should probably be updated so that a client that sets didAssociateFormControlsForFrame does not have to set didAssociateFormControls.

The idea is that the clients should transition from the old one to the new one.
Once a client opt in the new callback, it seems better for the old callback to become a no-op.

I think we should null check this.  Otherwise I think we'll introduce a rare crash.

[Michael Catanzaro]

As explained above, no check is needed, it's guaranteed to be nonnull. The assert is just there to document that.

I think you need to use #WebKitWebPage::form-controls-associated-for-frame for the link to be created.
