Bug 102354 – Avoid copying of ViewportArguments in computeViewportAttributes function

• Component: WebCore Misc.
• Status: REOPENED

[Mikhail Pozdnyakov]

Since r134749 we do not need copying of ViewportArguments parameter in computeViewportAttributes() as we're not modifying it any more.

Are you sure you dont need to change export symbols?

This change broke the Apple Windows Debug build:

12>   Creating library C:\cygwin\home\buildbot\slave\win-debug\build\WebKitBuild\Debug\lib\DumpRenderTree.lib and object C:\cygwin\home\buildbot\slave\win-debug\build\WebKitBuild\Debug\lib\DumpRenderTree.exp

After discussing this issue with Mikhail Pozdnyakov on IRC this morning, we decided to rollout this change so as to fix it offline.

For completeness, I tried to fix the build in <http://trac.webkit.org/changeset/134913>, but it didn't work out :( I reverted this attempt in the patch for bug #102472.

I've carefully checked exported symbols and did not find any reason it should cause build failure (all .def files are updated), logs say:
unresolved external symbol "struct WebCore::ViewportAttributes __cdecl WebCore::computeViewportAttributes(struct WebCore::ViewportArguments,int,int,int,float,class WebCore::IntSize)

which does not exist already, so I suppose the problem could have been solved by clean build triggering.
