Bug 207683 – Replace the usages of (IPC::Attachment fencePort) with IPC::MachPort

• Status: RESOLVED FIXED

[Peng Liu]

Some IPC messages use IPC::Attachment to carry fence ports, we need to use the class MachPort instead.

This patch looks good.

> Source/WebKit/UIProcess/Cocoa/VideoFullscreenManagerProxy.mm:795
> +    if (DrawingAreaProxy* drawingArea = m_page->drawingArea())

OK as-is. auto* could be used here too.

> Source/WebKit/UIProcess/Cocoa/VideoFullscreenManagerProxy.mm:799
> +    m_page->send(Messages::VideoFullscreenManager::SetVideoLayerFrameFenced(contextId, frame, fenceSendRight));

OK as-is.

> Source/WebKit/WebProcess/WebPage/WebPage.cpp:3176
> +void WebPage::setTopContentInsetFenced(float contentInset, const WTF::MachSendRight& machSendRight)

OK as-is. Could be improved a tiny bit by taking by rvalue reference then need to patch up other places in this patch though. The param name sounds a bit ambiguous too and same comment for same param in WebProcess code.

> Source/WebKit/WebProcess/WebPage/WebPage.cpp:3178
> +    m_drawingArea->addFence(machSendRight);

OK as-is. If ^^^ taken then could patch up addFence to take by rvalue reference and move into.
