I believe these need to be const char[].

I don't see any reason to output these with capitalization. In any case, we will
never output them over the wire, so simplify the production code below by using
lower-case.

Done.

[huangs, 2013/04/15 21:29:40]

Done.

+std::string kPriorityMedium("Medium");
+std::string kPriorityHigh("High");

+NET_EXPORT const std::string PriorityToString(CookiePriority priority) {
+  std::string ret;
+  if (priority == PRIORITY_HIGH)

just return from here.

[huangs, 2013/04/15 21:29:40]

Done (although this leads to longer code).

Well, you did also add 3 lines of whitespace ;)

The WS is not required. Up to you. Same in StringToCookiePriority

Consider whether you still find a case statement with returns instead of breaks
distasteful. It might make the code easier to read at this point.

+  else if (priority == PRIORITY_MEDIUM)
+    ret = kPriorityMedium;
+  else if (priority == PRIORITY_LOW)
+    ret = kPriorityLow;
+  else
+    NOTREACHED();  // Returns empty string.
+  return ret;
+}
+
+NET_EXPORT CookiePriority StringToPriority(const std::string& priority_str) {
+  std::string priority_comp(priority_str);
+  StringToLowerASCII(&priority_comp);
+  // Capitalize first letter to match case with constants.
+  if (!priority_comp.empty())
+    *(priority_comp.begin()) = base::ToUpperASCII(*(priority_comp.begin()));
+
+  CookiePriority ret = PRIORITY_DEFAULT;
+  if (priority_comp == kPriorityHigh)
+    ret = PRIORITY_HIGH;

[erikwright (departed), 2013/04/15 19:00:37]

just return the value directly here.

[huangs, 2013/04/15 21:29:40]

Done.

+  else if (priority_comp == kPriorityMedium)
+    ret = PRIORITY_MEDIUM;
+  else if (priority_comp == kPriorityLow)
+    ret = PRIORITY_LOW;
+  return ret;
