just to be sure: this context is going to be associated with a dedicated worker
or a shared worker (and not a shared worker), right? Can we document that?

[horo, 2017/05/17 10:33:52]

Done.

 class WorkerFetchContextImpl : public blink::WebWorkerFetchContext,
                                public mojom::ServiceWorkerWorkerClient {
  public:
   explicit WorkerFetchContextImpl(
       mojom::WorkerURLLoaderFactoryProviderPtrInfo provider_info);
   ~WorkerFetchContextImpl() override;
 
   // blink::WebWorkerFetchContext implementation:
   void InitializeOnWorkerThread(base::SingleThreadTaskRunner*) override;
   std::unique_ptr<blink::WebURLLoader> CreateURLLoader() override;
   void WillSendRequest(blink::WebURLRequest&) override;
   bool IsControlledByServiceWorker() const override;
   void SetDataSaverEnabled(bool) override;
   bool IsDataSaverEnabled() const override;

   void SetControllerServiceWorker(int64_t controller_version_id) override;
 
-  // Sets the service worker status of the parent frame.
+  // Sets the fetch context status of the parent frame.

[falken, 2017/05/17 08:40:26]

What's the "parent frame" when this is for a shared worker? There can be
multiple frames, right?

[horo, 2017/05/17 10:33:52]

Added comment.

   void set_service_worker_provider_id(int id);
   void set_is_controlled_by_service_worker(bool flag);
+  void set_is_secure_context(bool flag);

[falken, 2017/05/17 08:40:26]

Can you document what this flag means?

[horo, 2017/05/17 10:33:52]

Done.
