Bug 108612 – [WK2][Win] MessageID.h related changes broke the build

• Component: New Bugs
• Status: RESOLVED FIXED

[Zoltan Arvai]

In range of r141459 and r141528 there were several changes in CoreIPC that broke Qt windows build.
Probably its related to r141465, r141472, r141528 and 141538.

Trying to fix the build, more modifications needed as i see.

[Zoltan Arvai]

With the patch I got some other error messages:

C:\WebKitBuildSlave\proba\WebKit\Source\WebKit2\Platform\win\WorkQueueWin.cpp(147) : error C2065: 'm_isValidMutex' : undeclared identifier
C:\WebKitBuildSlave\proba\WebKit\Source\WebKit2\Platform\win\WorkQueueWin.cpp(148) : error C2065: 'm_isValid' : undeclared identifier

let's see....

I think you can just get rid of realBufferSize and use m_readBuffer.size() directly here. Without the ASSERT there I guess the comment doesn't add any value neither?

The attached patch should fix that part, I think.

[Zoltan Arvai]

Build is seems fine with MSVC. I'll create the aggregated patch for buildfix soon :)

Newline missing before this line?

corrected patch, sorry

[Simon Hausmann]

This patch doesn't touch any Qt specific files, so replacing [Qt] in the bug title with [WK2] :)

And sorry again. Replacing Qt with WK2 in changelog, too. I see Qt everywhere :)

I think it's better if WorkItemWin just used a RefPtr instead of manually reffing and dereffing.

[Zoltan Arvai]

Is that possible, that the current WorkQueueWin.cpp implementation has the required RefPtr functionality and doing ref - deref was not necessary in the last patch?

No, that is not possible:

    class WorkItemWin : public ThreadSafeRefCounted<WorkItemWin> {
    public:
        static PassRefPtr<WorkItemWin> create(const Function<void()>&, WorkQueue*);
        virtual ~WorkItemWin();

        Function<void()>& function() { return m_function; }
        WorkQueue* queue() const { return m_queue; }

    protected:
        WorkItemWin(const Function<void()>&, WorkQueue*);

    private:
        Function<void()> m_function;
        WorkQueue* m_queue;
    };

m_queue needs to be a RefPtr.

This should just return a raw pointer. Patch looks good otherwise!

Correcting raw pointer return. Thanks.

Is the Win EWS broken?

Who cares the Apple Win EWS here? Your patch touches only WK2 
files, but WK2 isn't supported by Apple Windows port. This
change can affect only Qt-WK2 Windows port.
