Bug 158299 – Introduce ResourceErrorBase::type

• Component: WebCore Misc.
• Status: RESOLVED FIXED

[youenn fablet]

ResourceErrorBase has three booleans to store whether being null, timeout, cancellation or a combination of all three.
It would be better to introduce a ResourceError type.

In addition to remove the possibility of having errors that can be timeout and null, this patch may allow adding easily new error types.

A "CrossOrigin" error type may be useful to:
- Remove ThreadableLoaderClient::didFailAccessControl/didFailRedirectCheck
- Move response cross-origin checks in SubresourceLoader in lieu of various loaders (DocumentThreadableLoader, ImageLoader...)

This looks like an improvement.  There's another patch I've seen recently changing the way we do errors with the FrameLoader.

> Source/WebCore/loader/EmptyClients.h:334
> +    ResourceError blockedError(const ResourceRequest&) override { return ResourceError(); }

Could we use { } ?

> Source/WebCore/platform/network/ResourceErrorBase.h:58
> +    void setAsCancellation() { m_type = Type::Cancellation; }

Could this have an assertion that type wasn't Timeout?  Could the assertion be even stricter?
Also, I think it would be nice to have a Type parameter required in the constructor.

> Source/WebCore/platform/network/ResourceErrorBase.h:93
> +    Type m_type { Type::Null };

It's confusing that this defaults to Null when there is a Default type.

OK

Yes, m_type should probably set at construct time once for all.

I was tempted to doing so but resisted to get a smaller patch.
I can handle it now or as a follow-up patch.

Right, let's change the name to Type::General and make it the default here.

I got other reviews that this was more readable this way for single assignment constructors. This style is consistent with other patches I made.
But I am fine changing to the bot style.
