nit: add a default case with NOTREACHED() << "Unknown action " << action;

Done.

[Daniel Erat, 2012/09/05 19:28:32]

nit: any reason that you actually need a scoped_ptr here instead of just
allocating this on the stack?

nit: move 'i' declaration into the loop condition

Done.

[Daniel Erat, 2012/09/05 19:28:32]

we talked earlier about sorting phone numbers and email addresses so the entry
with its 'primary' field set to true will come first.  how about doing something
like this instead:

  for (...) {
    const Contact_EmailAddress& email_address = ...;
    StringValue* value = Value::CreateStringValue(...);
    if (email_address.primary())
      CHECK(email_list->Insert(0, value));
    else
      email_list->Append(value);
  }

?

[zel, 2012/09/05 19:56:03]

Done.

+    const Contact_EmailAddress& email_address = contact->email_addresses(i);
+    email_list->Append(Value::CreateStringValue(email_address.address()));
+  }
+
+  std::string data;

[Daniel Erat, 2012/09/05 19:28:32]

is this something that you actually need to check here?  we won't even be
loading any contacts, let alone passing them to this code, when the flag is off.

[zel, 2012/09/05 19:56:03]

Fair enough. Removed.
