Bug 194651 – Make ServiceWorkerClientFetch closer to WebResourceLoader

• Component: Service Workers
• Status: RESOLVED FIXED

[youenn fablet]

Now that service worker registrations are in the network process, we could consider serve service worker content through the regular network process loading code path.
The first step is to make ServiceWorkerClientFetch closer to WebResourceLoader.

Could we make this a default parameter?

Do we want to just inform that a redirect happened, or will we in the future have a need for the service worker to be able to reject the redirect?

Could we just call m_formData.releaseNonNull() without WTFMove?

> Source/WebKit/WebProcess/Storage/WebServiceWorkerFetchTaskClient.h:86
> +    RefPtr<WebCore::SharedBuffer> m_buffer;

Can these be a Variant, or could we have more than one of these?

Making this a std::unique_ptr would save memory in the common case.

Sure, could be done as a separate patch.

When fetch event respondWith is called, there is no way back.
A DocumentLoader may trigger another service worker fetch which will be treated as another fetch event.

I updated the patch to make all of these a Variant with proper Ref<>, UniqueRef<>.
