From b2cd254c35b6b1b128beea0eacdb8e814d91e003 Mon Sep 17 00:00:00 2001 From: Kenta Moriuchi Date: Thu, 4 Jan 2024 13:12:38 +0900 Subject: fix: strict type check for cross realms (#21669) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Deno v1.39 introduces `vm.runInNewContext`. This may cause problems when using `Object.prototype.isPrototypeOf` to check built-in types. ```js import vm from "node:vm"; const err = new Error(); const crossErr = vm.runInNewContext(`new Error()`); console.assert( !(crossErr instanceof Error) ); console.assert( Object.getPrototypeOf(err) !== Object.getPrototypeOf(crossErr) ); ``` This PR changes to check using internal slots solves them. --- current: ``` > import vm from "node:vm"; undefined > vm.runInNewContext(`new Error("message")`) Error {} > vm.runInNewContext(`new Date("2018-12-10T02:26:59.002Z")`) Date {} ``` this PR: ``` > import vm from "node:vm"; undefined > vm.runInNewContext(`new Error("message")`) Error: message at :1:1 > vm.runInNewContext(`new Date("2018-12-10T02:26:59.002Z")`) 2018-12-10T02:26:59.002Z ``` --------- Co-authored-by: Bartek IwaƄczuk --- ext/node/polyfills/internal/console/constructor.mjs | 8 +++++--- 1 file changed, 5 insertions(+), 3 deletions(-) (limited to 'ext/node/polyfills/internal/console/constructor.mjs') diff --git a/ext/node/polyfills/internal/console/constructor.mjs b/ext/node/polyfills/internal/console/constructor.mjs index e9160cf70..45bca6675 100644 --- a/ext/node/polyfills/internal/console/constructor.mjs +++ b/ext/node/polyfills/internal/console/constructor.mjs @@ -5,7 +5,9 @@ // deno-lint-ignore-file prefer-primordials import { core } from "ext:core/mod.js"; -const ops = core.ops; +const { + op_preview_entries, +} = core.ensureFastOps(true); // Mock trace for now const trace = () => {}; @@ -502,7 +504,7 @@ const consoleMethods = { let isKeyValue = false; let i = 0; if (mapIter) { - const res = ops.op_preview_entries(tabularData, true); + const res = op_preview_entries(tabularData, true); tabularData = res[0]; isKeyValue = res[1]; } @@ -537,7 +539,7 @@ const consoleMethods = { const setIter = isSetIterator(tabularData); if (setIter) { - tabularData = ops.op_preview_entries(tabularData, false); + tabularData = op_preview_entries(tabularData, false); } const setlike = setIter || mapIter || isSet(tabularData); -- cgit v1.2.3
