Description David Kilzer (:ddkilzer) 2011-03-29 13:34:52 PDT
When resource load priorities are round-tripped through CFNetwork for the experimental HTTP pipelining feature, we currently map 4 WebCore priorities to 3 CFNetwork priorities.  This should be fixed so that the load priorities match when they are round-tripped.

Patch v2

Made a small fix in ResourceHandleMac.mm compared to Patch v1:

     if (isHTTPPipeliningEnabled()) {
-        int priority = mapResourceLoadPriorityToHTTPPipeliningPriority(m_priority);
-        wkSetHTTPPipeliningPriority(nsRequest, shouldForceHTTPPipeliningPriorityHigh() ? 2 : priority);
+        int priority = toHTTPPipeliningPriority(shouldForceHTTPPipeliningPriorityHigh() ? ResourceLoadPriorityHigh : m_priority);
+        wkSetHTTPPipeliningPriority(nsRequest, priority);
