Nit: #include <utility>

[Hzj_jie, 2017/04/26 22:05:56]

Done.

+KeyboardLockServiceImpl::~KeyboardLockServiceImpl() = default;
+
+// static
+void KeyboardLockServiceImpl::CreateMojoService(
+    RenderFrameHost* render_frame_host,
+    blink::mojom::KeyboardLockServiceRequest request) {
+  new KeyboardLockServiceImpl(std::move(request));

Is this leaked? The binding isn't a strong binding, and I see no delete.

[Hzj_jie, 2017/04/26 22:05:56]

I do not think so: the object is owned by binding_.

[dcheng, 2017/04/27 02:53:10]

Talked offline and we agree that this needs to be cleaned up.

I would just recommend using mojo::MakeStrongBinding() for now; we can change it
later if it doesn't make sense as the implementation is filled out.

Done.

For IPC reviews, it's generally beneficial to include the actual service
implementation--otherwise, it's hard to evaluate for the IPC security review. Is
there any possibility of doing that here?

[Hzj_jie, 2017/04/26 22:05:56]

I'd only say we still have bunch of changes needed to support this callback,
which is not likely to be able to be done in this change.

[dcheng, 2017/04/27 02:53:10]

Please include an IPC security reviewer on the followup CLs then.

[Hzj_jie, 2017/04/28 00:10:31]

Done.
