Created attachment 286772 [details] Adding FormData upload

Note the small difference of the request content-type between XHR and fetch API for FormData upload: XHR has a space before boundary (legacy), not fetch API (as per fetch spec). I guess XHR should be aligned. But from what I saw, chrome and Firefox also insert a space before boundary parameter for fetch API (and XHR I guess).

Thanks for the review.

FetchRequest built-in constructor takes a ScriptExecutionContext. The check is done in createJSObject. We could make setBody take a ScriptExecutionContext& but that would add never-used binding generated code and an unneeded if check. > > Source/WebCore/Modules/fetch/FetchRequest.cpp:300 > > + ASSERT(scriptExecutionContext()); > > What guarantees this assertion will not fail? internalRequest() is called from FetchLoader::start which would not be called if scriptExecutionContext is null. The check is done in DOMWindowFetch/WorkerGlobalScope::fetch. Maybe it would be clearer to pass a ScriptExecutionContext& as parameter in that case. > > Source/WebCore/Modules/fetch/FetchResponse.cpp:85 > > + ASSERT(scriptExecutionContext()); > > What guarantees this assertion will not fail? This is similar to the first case, the check is done in createJSObject.
