Bug 223094 – Drop some unnecessary RunLoop::isMain() / IsMainRunLoop() checks

• Component: WebCore Misc.
• Status: RESOLVED FIXED

[Chris Dumez]

Drop some unnecessary RunLoop::isMain() / IsMainRunLoop() checks. callOnMainThread() / ensureOnMainRunLoop() take care of calling their lambda synchronously when already on the main runloop.

I slightly prefer the "only capture protectedThis" style, but I guess you like the "capture both" style?

Better as a one-liner:

    delete toNPObjectProxy(npObject);

> Source/WebKit/WebProcess/Storage/WebServiceWorkerFetchTaskClient.cpp:225

Maybe we should just capture the three identifiers and not capture the object at all? Would be nice to not have to worry about reference counting at all.

Just call the local variable "proxy"?

Yes, I like capturing this because it makes the code more concise in the lambda.

OK

Good idea, will do.
