[webkit-dev] Correct relative URL behavior

[Xianzhu Wang]

Hi,

KURL's relative URL behavior is different between Chromium and non-Chromium
ports, because Chromium ports use KURLGoogle.cpp instead of KURL.cpp.

In KURL(base, relative), when base is a not hierarchical, WebKit's
KURL::string() returns relative, while Chromium's returns an empty string.
The behavior of Chromium causes
https://bugs.webkit.org/show_bug.cgi?id=55643 (Chromium unnecessarily
creates SVGImage when an SVG document contains images).

I'm wondering which behavior is correct. Assuming WebKit's KURL behavior is
correct, my first patch is to change KURLGoogle.cpp to match KURL.cpp, which
affects the result of fast/url/relative.html.
platform/chromium/fast/url/relative-expected.txt
contains all PASSs, while fast/url/relative-expected.txt contains 8 expected
FAILs, 2 of which relate to my question:

FAIL canonicalize('baz.html') should be . Was baz.html.
FAIL canonicalize(':foo') should be . Was :foo.

My questions are:
1. Are all the PASS expectations of fast/url/relative.html correct? If yes,
we should file a bug to track the failures of KURL.
2. With my patch, Chromium will produce the above two FAILs for
fast/url/relative.html. Is this acceptable to be rebaselined?

Thanks,
Xianzhu
