1. If an object needs a custom function to |write|, it will be added to |memory| in |JSStructuredCloneWriter| before calling the custom function. But in JSStructuredCloneReader::startRead we did the opposite. This will cause out-of-order if the custom function also writes some objects (e.g. WriteStructuredCloneImageData). We fix this by keeping the same order in |startRead|. 2. |JS_WriteTypedArray| should not call |writeTypedArray| directly, because it will miss an entry in |memory| for the typed array itself. We fix this by calling |startWrite| instead. Differential Revision: https://phabricator.services.mozilla.com/D24670 --HG-- extra : moz-landing-system : lando
