From 61d61448a91b74f889c33cad54e95f8fdb9d2c61 Mon Sep 17 00:00:00 2001 From: Gabriel Schulhof Date: Tue, 29 Oct 2019 18:59:09 -0700 Subject: deps: V8: cherry-pick e5dbc95 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Original commit message: [api] Fix handle leak when getting Context embedder data The `Context::SlowGetAlignedPointerFromEmbedderData()` method returns a pointer, so the fact that it allocates handles is not obvious to the caller. Since this is the slow path anyway, simply add a handle scope inside of it. The tests are also modified to perform the same check for the `Object` equivalent of this method.
