Comment on attachment 425357 [details] Patch View in context: https://bugs.webkit.org/attachment.cgi?id=425357&action=review > Source/WebKit/Scripts/webkit/messages.py:951 > + result.append(' ASSERT_NOT_REACHED_WITH_MESSAGE("Unhandled stream message %s to %llu", description(decoder.messageName()), decoder.destinationID());\n') These are not quite right. Nothing guarantees that destinationID() is an unsigned long long. We need to use PRIu64 (not sure I got that right) instead of %llu.
PRIu64 is the right specifier here indeed.
