This isn’t the best fix. The correct fix is to not capture this, since we’re not using it. Not sure we should be capturing protectedThis either.

Better fix is to wrap this line in:

#if !RELEASE_LOG_DISABLED
#endif

> Source/WebKit/WebProcess/Network/WebLoaderStrategy.cpp:359
> +#endif

I think this #endif should be up above, not wrapped around the entire block. We don’t want or need to nest the #if

> Source/WebKit/WebProcess/Storage/WebSWContextManagerConnection.cpp:160
>      RELEASE_LOG(ServiceWorker, "Created service worker %" PRIu64 " in process PID %i", serviceWorkerIdentifier.toUInt64(), getCurrentProcessID());
> +    UNUSED_VARIABLE(serviceWorkerIdentifier);

Better fix is to use data.serviceWorkerIdentifier in the RELEASE_LOG line and get rid of the local variable.

> Source/WebKit/WebProcess/WebPage/WebURLSchemeTaskProxy.cpp:55
> +static UNUSED_FUNCTION uint64_t pageIDFromWebFrame(const RefPtr<WebFrame>& frame)

Better fix is to put these functions inside #if !RELEASE_LOG_DISABLED.

But `this` is uses in RELEASE_LOG_IF_ALLOWED macro. It will be warned if RELEASE_LOG_DISABLED.

Right.

Ah, okay. Make sense.

Right.

I will add RELEASE_LOG_IF_ALLOWED for RELEASE_LOG_DISABLED case.

Ah, no. it is passed with WTFMove(data). We shouldn't use that. Wrap with #!RELEASE_LOG_DISABLED.

Don’t need this any more since you put a fix into RELEASE_LOG_IF_ALLOWED

Can we do something for this?

That was defined in SubresourceLoader.cpp, so I have to define that here for this file. Okay.
