] | Hi, I'm having hard time for getting the correct "this" context from the native callback by calling jerry_call_function, it always returned "global".
```javascript
export class ClassA
{
print()
{
console.log("This is from Class A\n");
}
set cb_event(cb)
{
native_driver_timer.setTimeoutEvent(cb);
}
constructor(){}
}
```
```c
static jerry_value_t function_native_driver_timer_setTimeoutEvent(const jerry_value_t func_value, /**< function object */
const jerry_value_t this_value, /**< this arg */
const jerry_value_t args[], /**< function arguments */
const jerry_length_t args_cnt) /**< number of function arguments */
{
jerry_release_value(jerry_call_function(args[0],
this_val,
NULL,
0));
return jerry_create_undefined();
}
```
```javascript
let ca = new ClassA();
ca.cb_event = (() => {
this.print(); // Undefined.
console.log(JSON.stringify(this)); //Always returning "global", wondering how to make "this" as a context of variable "ca".
});

"jerryscript-project",

] | I have several questions about the heap allocator which jerry is using, hope someone can help.
* the allocator have 2 different strategies, one is for 8bytes chunk allocation, the other is for large size chunk allocation. why jerry choose 8bytes alignment， not 4, 5 or 7. Is there any special consideration about this?
* In some scenario, i have found some memory fragment issue with jerry. In the future is there any plan that a compacting gc algorithm will be implemented?

] | Hello. I am creating a new issue as I haven't found a better contact. I implemented an integration for JerryScript for Fuzzilli fuzzer https://github.com/googleprojectzero/fuzzilli/pull/79 . It contains also an easy-to-use docker container or it could be invoked directly, as described in the [readme](https://github.com/googleprojectzero/fuzzilli/tree/master/Targets/Jerryscript) file. If you decide to give it a try, I believe it could still find some valuable bugs. | Implemented Fuzzilli Integration | https://api.github.com/repos/jerryscript-project/jerryscript/issues/3931/comments | 2 | 2020-06-25T10:15:59Z | 2020-07-23T08:00:17Z | https://github.com/jerryscript-project/jerryscript/issues/3931 | 645,441,934 | 3,931 |

When executing the testcase below, jerry throws a RangeError when the third argument is present and the value is undefined. According to ES6.0, the expected output should be 0. The value of [[ByteLength]] internal slot may not satisfy the spec. This is an issue about DataView constructor.
#### version
`bd1c4df`
#### testcase
```javascript
var NISLFuzzingFunc = function(){
var a = DataView(new ArrayBuffer(256),0,undefined);
print(a.getInt16(0));
};
var result = NISLFuzzingFunc();
```
#### output
```
RangeError: Start offset is outside the bounds of the buffer.
```
#### expected output
```
0
```

] | When executing the testcase below, the result when the second argument of `JSON.stringify` is `[]` is different from when the parameter is a non-empty array. According to the ES6.0, the expected output should be `{}`. And when executing this testcase on other engines, (like chakraCore, v8, and spiderMonkey) I get the expected output. This may be an issue about `JSON.stringify`.
#### version
`bd1c4df`
#### testcase
```javascript
var NISLFuzzingFunc = function (nislMutationParameter0, nislMutationParameter1, nislMutationParameter2) {
return JSON.stringify(nislMutationParameter0, nislMutationParameter1, nislMutationParameter2);
};
var nislMutationArgument0 = {"4664":false,"18836":true};
var nislMutationArgument1 = [];
var nislMutationArgument2 = "abc";
var NISLCallingResult = NISLFuzzingFunc(nislMutationArgument0, nislMutationArgument1, nislMutationArgument2);
print(NISLCallingResult);
```
#### output
```
{
abc“4664":false,
abc”18836":true

#### expected output

In the body of the issue, optionally give a free-form text description of the
bug. Give the context necessary for others to understand the problem.
Then, provide information necessary to reproduce the bug.
Omit sections that are irrelevant for the bug report, but note that information
like git revision, build platform, build command, and test case are required in
almost all cases.

] | Although `Error#stack` is a non-standard property,
it would be nice to follow other implementations
and return a `String` instead of `Array`.
```javascript
var err = new Error("Er")
print(typeof err.stack, Array.isArray(err.stack))
// node returns: string false
// jerry returns: object true
```
Just message + stack joined with newline would be enough as all stack using libraries does expect different format on different environments.

I know jerryscript does not support all es6 standards, so I want to know if this is an unimplemented feature or a bug? Looking forward your reply, thanks!

"jerryscript-project",
"jerryscript"
] | Traditionally, JerryScript has been a fully ES5.1-compatible JavaScript engine. As the standard evolved, the community started adding features from the next edition of EcmaScript (ES6 or ES2015) into a new profile (configuration) of the engine. The original configuration was called the es5.1 profile, while the new one got the name es2015-subset profile. The original idea was to complete the ES2015 profile -- so as to be able to drop the "-subset" suffix -- and then move on to the next edition of the standard, and so on. I.e., the intent was to support all editions of the standard and allow our users to select the edition they need when they configure and build JerryScript.
It turns out that this is not a maintainable approach and does not even meet the needs of the users. Most JavaScript programmers use the latest edition of the standard, whichever that is, and expect engines to support that edition. Or, at least, support something close to that. Even if we finished the exact implementation of the ES6 specification, that would be both outdated and not even the subset of the latest edition of JavaScript. (Yes, there have been backward incompatible changes in the spec since 2015.) And we definitely wont be able to maintain different ES2015, ES2016, ES2017, ES2018, ES2019 (etc.) configurations. (Moreover, we couldn't even properly test conformance, as the test262 conformance suite has ceased releasing test suites for the different editions of the language after ES5.1.)
Therefore, I propose to keep the original ES5.1 profile (because that's a fully spec-compatible and mature configuration, often enough for constrained applications), but otherwise target the always-latest version of the EcmaScript standard (let's call it the ES.Next profile -- disclaimer: I haven't invented the term).
Notes:
- This would cause a big one-time churn in the code base, as all ES2015 macro guards would need a rename (to something like ESNEXT?). Most probably it's not even only the macros.
- This would cause some backward incompatibility as well, at least build system-wise, as profile name and feature guard names would change. Embedders relying on these would break.
- IMO, we still could and should keep the feature guards in the code base to allow users to trim down functionality. Let's remember that JerryScript is for constrained devices.
