The function passed to\n * beginHiddenCallStack is the first hidden function, while the function passed\n * to endHiddenCallStack is the first shown function.\n *\n * When an error is thrown _outside_ of the hidden zone, everything between\n * beginHiddenCallStack and endHiddenCallStack will not be shown.\n * If an error is thrown _inside_ the hidden zone, then the whole stack trace\n * will be visible: this is to avoid hiding real bugs.\n * However, if an error inside the hidden zone is expected, it can be marked\n * with the expectedError(error) function to keep the hidden frames hidden.\n *\n * Consider this call stack (the outer function is the bottom one):\n *\n * 1. a()\n * 2. endHiddenCallStack(b)()\n * 3. c()\n * 4. beginHiddenCallStack(d)()\n * 5. e()\n * 6. f()\n *\n * - If a() throws an error, then its shown call stack will be \"a, b, e, f\"\n * - If b() throws an error, then its shown call stack will be \"b, e, f\"\n * - If c() throws an expected error, then its shown call stack will be \"e, f\"\n * - If c() throws an unexpected error, then its shown call stack will be \"c, d, e, f\"\n * - If d() throws an expected error, then its shown call stack will be \"e, f\"\n * - If d() throws an unexpected error, then its shown call stack will be \"d, e, f\"\n * - If e() throws an error, then its shown call stack will be \"e, f\"\n *\n * Additionally, an error can inject additional \"virtual\" stack frames using the\n * injectVirtualStackFrame(error, filename) function: those are injected as a\n * replacement of the hidden frames.\n * In the example above, if we called injectVirtualStackFrame(err, \"h\") and\n * injectVirtualStackFrame(err, \"i\") on the expected error thrown by c(), its\n * shown call stack would have been \"h, i, e, f\".\n * This can be useful, for example, to report config validation errors as if they\n * were directly thrown in the config file.\n */\n\nconst ErrorToString = Function.call.bind(Error.prototype.toString);\n\nconst SUPPORTED =\n !!Error.captureStackTrace &&\n Object.getOwnPropertyDescriptor(Error, \"stackTraceLimit\")?.writable === true;\n\nconst START_HIDING = \"startHiding - secret - don't use this - v1\";\nconst STOP_HIDING = \"stopHiding - secret - don't use this - v1\";\n\ntype CallSite = NodeJS.CallSite;\n\nconst expectedErrors = new WeakSet<Error>();\nconst virtualFrames = new WeakMap<Error, CallSite[]>();\n\nfunction CallSite(filename: string): CallSite {\n // We need to use a prototype otherwise it breaks source-map-support's internals\n return Object.create({\n isNative: () => false,\n isConstructor: () => false,\n isToplevel: () => true,\n getFileName: () => filename,\n getLineNumber: () => undefined,\n getColumnNumber: () => undefined,\n getFunctionName: () => undefined
