Bug 183010 – [Curl] Remove unnecessary copied ResourceRequest member variable.

• Component: WebCore Misc.
• Status: RESOLVED FIXED

[Basuke Suzuki]

It was used when both redirect and authentication happens, but by adding const reference getter to CurlRequest, it is no longer needed.

I am not clear what PreflightRequest means in that context.
In the context of HTTP, preflight requests are used for CORS, but this does not seem related.
Would there be a better name to explicit the purpose. Is it a mechanism to do conditional requests?

> Source/WebCore/platform/network/curl/ResourceHandleCurl.cpp:136
> +Ref<CurlRequest> ResourceHandle::createCurlRequest(ResourceRequest& request, PreflightRequest preflight)

Would it make sense to take a ResourceRequest&& in case CurlRequest is probably creating its own copy of the request?

Is the isolatedCopy needed here?

Ah, right. I use preflight not meaning about CORS, but general meaning of preparation by parsing the headers or such info. Is `Preprocess` the better name?

Okay, i'll think about it.

Ditto.

Preprocess is very generic as well and it seems that this is related to an existing cache so I would try to come up with a name inducing the notion of cache.

If this is related to HTTP conditional request/revalidation, I would try to make the name as specific as possible.

Patch

Rename Preflight to RequestStatus which indicates it's new or reuse. Also stop isolateCopy, but simple copy. Move is not used here because original request need to be valid in m_firstRequest.
