REGRESSION (r194898): Multi download of external SVG defs file by <use> xlinks:href (caching)
​https://bugs.webkit.org/show_bug.cgi?id=156368
<rdar://problem/25611746>

Reviewed by Simon Fraser.

Source/WebCore:

We would load svg resources with fragment identifier again because the encoding never matched.

Test: http/tests/svg/svg-use-external.html

  • loader/TextResourceDecoder.cpp:

(WebCore::TextResourceDecoder::setEncoding):
(WebCore::TextResourceDecoder::hasEqualEncodingForCharset):

Encoding can depend on mime type. Add a comparison function that takes this into account.

(WebCore::findXMLEncoding):

  • loader/TextResourceDecoder.h:

(WebCore::TextResourceDecoder::encoding):

  • loader/cache/CachedCSSStyleSheet.h:
  • loader/cache/CachedResource.h:

(WebCore::CachedResource::textResourceDecoder):

Add a way to get the TextResourceDecoder from a cached resource.

  • loader/cache/CachedResourceLoader.cpp:

(WebCore::CachedResourceLoader::determineRevalidationPolicy):

Use the new comparison function.

  • loader/cache/CachedSVGDocument.h:
  • loader/cache/CachedScript.h:
  • loader/cache/CachedXSLStyleSheet.h:

LayoutTests:

  • http/tests/svg/resources/symbol-defs.svg: Added.
  • http/tests/svg/svg-use-external-expected.txt: Added.
  • http/tests/svg/svg-use-external.html: Added.
