+
+ The parser may end up yielding during XHR or DOMParser parsing even though those should be
+ synchronous. This appears to be a long standing bug that was made more visible by r277818
+ because it makes the parser yield more eagerly. This only affects cases where the document
+ being parsed contains <script> tags as those are considered potential yield points.
+
+ Tests: http/tests/xmlhttprequest/xhr-and-parse-large-document.html
+ http/tests/xmlhttprequest/xhr-large-document.html
+
+ * dom/Document.cpp:
+ (WebCore::Document::setContent):
+
+ Explicitly parse synchronously. The comment was wrong, nothing forces parser flushing on close().
+
+ * dom/DocumentParser.h:
+ (WebCore::DocumentParser::appendSynchronously):
+ * html/parser/HTMLDocumentParser.cpp:
+ (WebCore::HTMLDocumentParser::append):
+ (WebCore::HTMLDocumentParser::appendSynchronously):
+ * html/parser/HTMLDocumentParser.h:
+ * html/parser/HTMLParserScheduler.cpp:
+ (WebCore::HTMLParserScheduler::shouldYieldBeforeExecutingScript):
+
+ Also avoid script yielding if script execution is not allowed.
