"jerryscript-project",
"jerryscript"
] | I've got a bug that only shows up when cross compiling for a raspberry pi target. The code base was cloned from github in October 2019. Unfortunately, the git information wasn't preserved when it was cloned. It looks like the relevant functions haven't changed since then. I'm not terribly familiar with the jerryscript code base so if someone could weigh in and help debug, that would be great.
On the raspberry pi target, I'm getting a stack smash in ecma_errol0_dtoa()
. The backtraces and whatnot are shown below. It appears that in ecma_errol0_dtoa() iterates around the loop "while (high_bound.value != 0.0 || high_bound.offset != 0.0)" adding 0x30 to the buffer until it walks up the stack and clobbers something that causes the crash.
The maddening thing is that this bug only shows up on the raspberry pi builds and only triggers every few builds. The X64 and ESP8266 targets never have the same crash.

arm-unknown-linux-gnueabi-gcc (crosstool-NG 1.24.0) 8.3.0
###### Build steps
python tools/build.py --profile=minimal --external-context=ON --verbose --clean --toolchain cmake/toolchain_raspberry_pi.cmake --lto off --jerry-cmdline off
###### Javascript
print('Task Init');
automation.thisDevice.deviceID="8acaf075-2edd-4c27-ab9b-74c62b14d41d";
var p=automation.points[0];
print("Initial point",JSON.stringify(p));
This is the output on a loop that didn't crash. The conversion is obviously bad here as well.
Initial point {"globalPointID":"20605adf-9566-80eb-7646-9a28c5fa3af3","localPointID":"aaaaaaaa-bbbb-cccc-dddd-eeeeeeeeeeee","description":"Percent door open","value":0.0005000000249999986823290498705318896099925041198730468750,"type":7}
p is a structure created in C. The double that it's trying to convert to a string is created using this function.
jerry_value_t pointValueToJerryValue(PointValueVariant* v){
debug3("pointValueToJerryValue\n");
switch (v->type){
case PointTypeInvalid:
case PointTypeUnknown:
return jerry_create_null();
case PointTypeBoolean:
return jerry_create_boolean(v->value.boolean);
case PointTypeInteger:
return jerry_create_number(v->value.integer);
case PointTypeDouble:
return jerry_create_number(v->value.dbl);
default:
error2("Cannot convert this point type to javascript\n");
return jerry_create_undefined();
}
}
I'm happy to provide a test binary with the issue.

] | I have a question about ToLength function. I analyzed usage of Array.prototype.Map and it resulted in wrong output for lengths bigger than **2<sup>32</sup>**
###### Test code:
```js
function callbackfn(val, idx, obj) {
print("Inside callback, idx:", idx);
return val;
}
var obj = { 0: 5, 1: 13, length: "Infinity" };
var ret = Array.prototype.map.call(obj, callbackfn);
print(ret)
```
###### Output:
```
Inside callback, idx: 0
Inside callback, idx: 1
[application hangs]
```
###### Expected output:
```
RangeError
```
Application hangs, because JerryScript parses **Infinity** to **2<sup>32</sup>-1** and in internal functions it is just passed as *unit_32t* variable.
In [ES6 ToLength](http://www.ecma-international.org/ecma-262/6.0/#sec-tolength) function there is limit to **2<sup>53</sup> - 1** and it differs with [ES5.1 ToUint32](http://www.ecma-international.org/ecma-262/5.1/#sec-9.6) (which plays role of ToLength function).
I see that in the JerryScript both implementations use limits equal to **UINT32_MAX**:
[ecma-conversion.c:943](https://github.com/jerryscript-project/jerryscript/blob/1b1460e61fa468829984134c92761088d3cc8cbd/jerry-core/ecma/operations/ecma-conversion.c#L943).
I noticed that the same difference occurs in [String.prototype.split](https://github.com/jerryscript-project/jerryscript/blob/1b1460e61fa468829984134c92761088d3cc8cbd/jerry-core/ecma/builtin-objects/ecma-builtin-string-prototype.c#L795) and [RegExp.prototype [ @@split ]](https://github.com/jerryscript-project/jerryscript/blob/1b1460e61fa468829984134c92761088d3cc8cbd/jerry-core/ecma/operations/ecma-regexp-object.c#L1826)
Is there any specific reason why it is limited to 32 bits? Of course changing it would result in many modifications - because we would need to pass 64 bits variable in *ecma_op_to_length* function and change all uses.
Maybe it is made on purpose - JerryScript aims to low memory devices - probably nobody would ever need that sizes of Arrays / Strings? | ToLength function uses different limits than stated in ES6 standard | https://api.github.com/repos/jerryscript-project/jerryscript/issues/3691/comments | 4 | 2020-04-22T12:43:48Z | 2020-07-29T20:17:28Z | https://github.com/jerryscript-project/jerryscript/issues/3691 | 604,727,657 | 3,691 |

After analysis, it is found that this is an assert. The key place for assert is in
Through the index, the conversion of the string is through the index, when encountering the object, the object will be found through the pointer. Because `alphabetR` pushed itself, creating a circular list, and then in `toLocaleString`,
Constantly looping to find its own object, causing the object to find a reference error, that is, `ERR_REF_COUNT_LIMIT`.

] | According to the ES5.1, `/^[\s]/` means a space character from the beginning of a string, and the `String.prototype.split` method divides a String into an ordered set of substrings. The division of the testcase is done by searching for the pattern `/^[\s]/`. And the output is different from other engines like V8, SpiderMonkey and javascriptCore. It maybe an issue of jerryscript.

[
"jerryscript-project",
"jerryscript"
] | First of all, when reporting a bug, give the issue a descriptive title.
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.
###### JerryScript revision
Identify the git hash(es) or tag(s) where the issue was observed.
###### Build platform
Name the build platform. E.g., copy the output of
`echo "$(lsb_release -ds) ($(uname -mrs))"` (on Linux),
`echo "$(sw_vers -productName) $(sw_vers -productVersion) ($(uname -mrs))"` (on macOS), or
`python -c "import platform; print(platform.platform())"` (should work everywhere).
###### Build steps
Describe how to build JerryScript. Give all the necessary details of the build
(e.g., environment variables, command(s), profile, command line options, etc.).
E.g.:
```sh
tools/build.py --clean --debug
```
Or:
```sh
mkdir build && cmake -H. -Bbuild && make -C build
```
Even if the bug was originally observed when JerryScript was integrated into a
larger project, try to reproduce it with as few external code as possible,
preferably by building the `jerry` command line tool.
###### Build log
Copy the build log if the reported issue is a build problem. Do a verbose build
if necessary. Try and trim the log to relevant parts.
###### Test case
Give the JavaScript input that should be passed to the engine to trigger the
bug. Try and post a reduced test case that is minimally necessary to reproduce
the issue. As a rule of thumb, use Markdown's fenced code block syntax for the
test case. Attach the file (renamed to .txt) if the test case contains
'problematic' bytes that cannot be copied in the bug report directly.
###### Execution platform
Unnecessary if the same as the build platform.
###### Execution steps
List the steps that trigger the bug.
E.g., if a bug is snapshot-specific:
```sh
build/bin/jerry-snapshot generate -o testcase.js.snapshot testcase.js
build/bin/jerry --exec-snapshot testcase.js.snapshot
```
Unnecessary if trivial (i.e., `build/bin/jerry testcase.js`).
###### Output
Copy relevant output from the standard output and/or error channels.
###### Backtrace
In case of a crash (assertion failure, etc.), try to copy the backtrace from a
debugger at the point of failure.
###### Expected behavior
Describe what should happen instead of current behavior. Unnecessary if trivial
(e.g., in case of a crash, the trivial expected behavior is not to crash).

] | Hello,
I'm writing an encoding function from string to Uint8Array based on `'ascii'` encoding (1 char to 1 byte).
I considered the functions `jerry_string_to_char_buffer()` and `jerry_string_to_utf8_char_buffer()`, but it encodes to two or more bytes for exceeding char code 127 (128 ~ 255).
Here is an example of ascii encoding in Node.js:
```js
> var s = String.fromCharCode(0, 1, 127, 128, 255);
> var buf = new Buffer(s, 'ascii'); // <Buffer 00 01 7f 80 ff>
```
Is there any function or way to get char code at particular index from a string? (like `jerry_string_char_code_at()`).
Thank you in advance. | Question: Is there C API corresponds to `string.charCodeAt()`? | https://api.github.com/repos/jerryscript-project/jerryscript/issues/3622/comments | 2 | 2020-03-18T08:18:31Z | 2020-03-27T02:49:20Z | https://github.com/jerryscript-project/jerryscript/issues/3622 | 583,549,536 | 3,622 |

] | Hello,
I'm going to implement 'length' property of bound function.
I think that there are 2 approaches as belows.
1) Adding 'length' property when each bound function generated
This approach is simple but all bound function objects always hold 'length' property whether it is really used or not.
2) Lazily insert 'length' property
Adding 'length' property when it is accessed for the first time. This approach could save memory, but we should hold the length of target function when each bound function is generated.
From the standard [es6 19.2.3.2](https://www.ecma-international.org/ecma-262/6.0/#sec-function.prototype.bind), 'length' property of bound function is calculated using the length of target function and its number of arguments.
number of arguments is already stored in `ecma_extended_object_t::u::bound_function::args_len_or_this`, but the length of target function is not.
```js
var foo = function (x,y) {};
var bound1 = foo.bind(null);
delete foo.length;
var bound2 = foo.bind(null);
print(bound1.length); // 2 (length property is defined when bound function is generated)
print(bound2.length); // 0
```
From the above case, we even cannot calculate the length property lazily because the length value of target function could be changed before the moment.
To resolve this issue, I'm considering storing the length value of target function into additional space outside the `ecma_extended_object_t` by allocating a one-slot bigger ecma_extended_object_t using `ecma_create_object()` when creating a bound function object.
Intialization of length property could be marked by pointer with tag (jmem_cpointer_tag_t) which is similar to the case of function object.
Which one do you prefer? | Adding 'length' property to bound function | https://api.github.com/repos/jerryscript-project/jerryscript/issues/3615/comments | 1 | 2020-03-16T11:37:13Z | 2020-04-04T00:04:03Z | https://github.com/jerryscript-project/jerryscript/issues/3615 | 582,221,874 | 3,615 |

] | As stated in [ES6 23.1.3.5](https://www.ecma-international.org/ecma-262/6.0/#sec-map.prototype.foreach), elements added after the call to __forEach__ begins should be visited.
So new element added in callback needs to be visited after _old_ elements.
###### Test code:
```js
var map = new Map;
map.set('a', 1);
map.set('b', 2);
var l = 0;
map.forEach(function(value, key) {
print(key, value);
if(l === 0) {
map.set('c', 3);
}
l++;
});
print("Loops:", l);
```
###### Output:
```
a 1
b 2
Loops: 2
```
###### Expected Output:
```
a 1
b 2
c 3
Loops: 3
```
I have checked current implementation and it looks like list of the properties' names is gathered at the beginning of execution and used till the end.
I think there should be some check after each callback execution, which would update properties' list.
The problem is in optimal implementation of this function - properties are stored in reversed singly linked list - new elements are added at the beginning (these elements should be listed at the end of foreach).
Something like internal iterator for collection object would be helpful, but this requires invalidating properties and deleting them not directly but a bit later by GC. But this needs a bit of additional memory for each collection's property and will be time consuming.
Is there any special reason why property list is reversed? Is this for optimization of adding new properties or it affects also implementations of other functions? | Map.forEach omits newly added elements | https://api.github.com/repos/jerryscript-project/jerryscript/issues/3592/comments | 1 | 2020-02-26T14:15:42Z | 2020-03-17T18:30:56Z | https://github.com/jerryscript-project/jerryscript/issues/3592 | 571,407,379 | 3,592 |

] | Hi jerryscript Community 🤗
I've been asked to help make sure that all the OpenJS Foundation project communities are aware that the deadline for our [OpenJS Conference Call for Proposals](https://events.linuxfoundation.org/openjs-world/program/cfp/) has been extended through Feb. 28. Previously, this event was called 'Node + JS Interactive' and it leaned heavily toward Node.js. We're hoping to have a wider range of sessions about all the OpenJS Foundation projects, so we'd love to see presentations from all the foundation projects!
I also wanted to make sure you're aware of the Collaborator's Summit, an event focused on project maintainers, collaborators & contributors. The goal for the collab summit is to provide opportunities for face-to-face working sessions within a single project or across multiple projects. So if you wanted to get your core team together you could do that, or if you want to have a session for new contributors to your project, or if you wanted to work across multiple OpenJS Foundation projects on issues like accessibility, privacy, security, modules, etc. you could do that too. **If you're interested in securing session space at the collab summit, please ping me here, reach out on slack or twitter, or open an issue on the [/summit](https://github.com/openjs-foundation/summit) repo.**
The OpenJS World conference is June 23-24 and Collaborator's Summit is June 25-26 in Austin, TX. These are ticketed events, but **members of OpenJS Foundation project communities are eligible for [Travel Fund](https://github.com/openjs-foundation/cross-project-council/blob/master/project-resources/MEMBER_TRAVEL_FUND.md) assistance.** If you have questions or would like to find out more, please chime in on our /summit repo.
as always, let me know how I can help <3

] | As ES6 standard says in [19.4.2.2 - 19.4.2.14](https://www.ecma-international.org/ecma-262/6.0/#sec-symbol.hasinstance) Symbol properties should have the attributes set to **false**.
{ [[Writable]]: **false**, [[Enumerable]]: **false**, [[Configurable]]: **false** }.
###### Test code:
```js
["hasInstance", "isConcatSpreadable", "iterator", "keyFor",
"match", "prototype", "replace", "search", "species", "split",
"toPrimitive", "toStringTag", "unscopables"].forEach(function (v) {
var desc = Object.getOwnPropertyDescriptor(Symbol, v)
print("Symbol." + v + ":", desc.writable, desc.enumerable, desc.configurable);
});
```
###### Output:
```
Symbol.hasInstance: true false true
Symbol.isConcatSpreadable: true false true
Symbol.iterator: true false true
Symbol.keyFor: true false true
Symbol.match: true false true
Symbol.prototype: false false false
Symbol.replace: true false true
Symbol.search: true false true
Symbol.species: true false true
Symbol.split: true false true
Symbol.toPrimitive: true false true
Symbol.toStringTag: true false true
Symbol.unscopables: true false true
```
###### Expected output:
```
Symbol.hasInstance: false false false
Symbol.isConcatSpreadable: false false false
Symbol.iterator: false false false
Symbol.keyFor: true false true
Symbol.match: false false false
Symbol.prototype: false false false
Symbol.replace: false false false
Symbol.search: false false false
Symbol.species: false false false
Symbol.split: false false false
Symbol.toPrimitive: false false false
Symbol.toStringTag: false false false
Symbol.unscopables: false false false
```
As I checked, this bug comes from #3490 . I think that **INTRINSIC_PROPERTY** macro should have flag parameter set to **ECMA_PROPERTY_FIXED** .
But this will also change behaviour of other properties created with that macro:
* _Array.prototype.values_
* _Array.prototype[Symbol.iterator]_
These properties should have { [[Writable]]: **true**, [[Enumerable]]: **false**, [[Configurable]]: **true** }, as stated in [ES 6 17](https://www.ecma-international.org/ecma-262/6.0/#sec-ecmascript-standard-built-in-objects)
So it looks like other macro is needed, i.e. **INTRINSIC_PROPERTY_CONFIGURABLE.**
Does it sound reasonable? If yes, then I could implement this and add some tests. | Symbol properties have invalid attributes | https://api.github.com/repos/jerryscript-project/jerryscript/issues/3578/comments | 2 | 2020-02-21T14:46:44Z | 2020-02-24T13:06:15Z | https://github.com/jerryscript-project/jerryscript/issues/3578 | 568,998,634 | 3,578 |

The current process of implementing new es6 features looks not optimal because developer should manually add test files.
How about using es6-version `test262` (https://github.com/tc39/test262)?
test262 tests each language feature in a single file, so it would help finding bugs and eventually speed up development.
(I found that JerryScript already has test262 suite but it is for es5.1)

] | Hi there,
I have a question about compilation methodology of JerryScript.
It seems that JerryScript generates all bytecode for the whole source code at once (correct me if I'm wrong).
I think that it is inefficient for memory consumption because this approach holds the entire bytecode in memory but only part of source code is simultaneously executed during the runtime.
Is there any special reason for eager compilation?
And I have one more question.
Do you have any plan to implement the latest ECMA standard such as es10?
I ask you this because I also want to contribute to this project, so I'm searching for items now. | Why does JerryScript generate the all bytecode at once? | https://api.github.com/repos/jerryscript-project/jerryscript/issues/3548/comments | 2 | 2020-02-07T07:53:26Z | 2020-02-10T04:47:30Z | https://github.com/jerryscript-project/jerryscript/issues/3548 | 561,477,516 | 3,548 |

}
sampeFunc()
{
this.x[0]++; // crash here
return this.x;
}

As far as I understand line "var s = super.sampleFunc()" should emit "CBC_EXT_SUPER_PROP_CALL".

] | Hi , all
I have noted many jerry APIs are marked as `release_value` needed for the returned value of those API, for example, [jerry_create_array](https://github.com/jerryscript-project/jerryscript/blob/master/jerry-core/api/jerry.c#L1372).
And for some APIs, such as `jerry_create_undefined()`, that note is not declared in code, but in some documents, the sample code is showing the jerry_release_value() is needed for them.
For example, the 'jerry_create_bool()' mentioned [here](https://github.com/jerryscript-project/jerryscript/blob/master/docs/06.REFERENCE-COUNTING.md).
Just want to confirm, if we called jerry_create_undefined()/jerry_create_bool() by ourself, should we remember to call **jerry_release_value** to release it somewhere?

] | Hi,
I am running Jerryscript on a microcontroller and I was wondering if there is a way to step the execution of JS from C.
For example lets say the Javascript is busy going around in a loop like while(1), could the C program dictate the speed of execution? Like, instead of
```
jerry_run(parsed_code);
```
we could have
```
jerry_load(parsed_code);
while(1){
jerry_next_tick();
// Do other things here, like handle Bluetooth, I/O, sleep, etc.
}
```
Alternatively if this is not impossible, is there a way to either have a yield call from JS or a pause one from C?
Similar issue #1356
