According to ES6, the argument will be processed by `ToObject`. It‘s not appropriate to throw an error if argument is not an object.

###### Build steps
```
python tools/build.py --clean --logging=on --line-info=on --error-messages=o n --cpointer-32bit=on --mem-heap=1572864 --profile=es2015-subset
```
###### Test case
```
var NISLFuzzingFunc = {
var text = 'x';
var index = Math.random() - 1;
print( text.charAt(0));
print( text.charAt(index));
print( text.charAt(index) === "");
}
NISLFuzzingFunc();
```
###### Execution steps
`jerryscript/build/bin/jerry testcase.js`
###### Output
```
x
true
```
###### Expected behavior
```
x
x
false
```
###### Description:
The variable named `index` is a negative number bigger than -1, and according to Standard ECMA-262 5.1 Edition , the [String.prototype.charAt(pos)](http://www.ecma-international.org/ecma-262/5.1/index.html#sec-15.5.4.4) will call [ToInteger](http://www.ecma-international.org/ecma-262/5.1/index.html#sec-9.4) to process the `pos`. The output of `print( text.charAt(index))` and`print( text.charAt(0))` are the same, which should be 'x'.

[
"jerryscript-project",
"jerryscript"
] | In [tools] directory there are several *.sh scripts that are supposed to work for debian/ubuntu dependency installation for lib building.
Let's take **apt-get-install-deps.sh**
When I try to build in jenkins/docker I get this error (I use **FROM debian:stretch**):
```
[2019-11-07T04:44:32.865Z] [91mtools/apt-get-install-deps.sh: line 17: sudo: command not found
[2019-11-07T04:44:32.866Z] [0m[91mtools/apt-get-install-deps.sh: line 18: sudo: command not found
```
Reason is simple, since it is docker, you are root by the default, and root requires no sudo (and sudo is not installed by the default).
Yes we can install sudo earlier and/or add the user to the sudo group, but there is also solution I use for another scripts, which are building another libraries:
```
#!/bin/bash
if [ "$(whoami)" != "root" ]; then
SUDO=sudo

May be it would be a good idea to add that to all *.sh scripts? | Fixing "sudo" usage for dependency installation | https://api.github.com/repos/jerryscript-project/jerryscript/issues/3288/comments | 2 | 2019-11-07T12:26:50Z | 2019-11-14T09:20:31Z | https://github.com/jerryscript-project/jerryscript/issues/3288 | 519,236,077 | 3,288 |

"jerryscript-project",

] | Hello,
I've found a possible security bug of JerryScript interpreter.
Here is a simple example:
```JavaScript
function bar(a) {
print("should be 10 by 'a=10': ", a[0]);
a.hasOwnProperty(0);
print("should be 10, but 20: ", a[0]);
}
function foo(a) {
print("should be 20: ", a);
a = 10;
bar(arguments);
}
foo(20);
```
I believe that the example code would be easily understandable.
If we apply 'hasOwnProperty' for the properties of the 'arguments' object, it turns to the original argument value instead of the value overwritten by the program.
It could leak a secret of a function argument if the function passes the argument object to an untrusted function.

] | Hello!
At this moment I've tried to make dynamic memory allocation. Scripts that will be used are static, but i don't know exact memory consumption of them. Now memory allocation works like in tutorials:
```
void * context_alloc(size_t size, void *cb_data_p)
{
return malloc(size);
}
jerry_context_t* create_context(size_t context_size_in_KB)
{
return jerry_create_context(context_size_in_KB * 1024, context_alloc, NULL);;
}
void initial_context_create(size_t context_size_in_KB)
{
_context_pointer = create_context(context_size_in_KB);
jerry_port_default_set_current_context(_context_pointer);
}
jerry_context_t* _context_pointer;
main()
{
initial_context_create(1);
jerry_init(JERRY_INIT_MEM_STATS);
}
```
And tried to do something like this:
```
void * context_alloc(size_t size, void *cb_data_p)
{
return malloc(size);
}
jerry_context_t* create_context(size_t context_size_in_KB)
{
return jerry_create_context(context_size_in_KB * 1024, context_alloc, NULL);;
}
void initial_context_create(size_t context_size_in_KB)
{
_context_pointer = create_context(context_size_in_KB);
jerry_port_default_set_current_context(_context_pointer);
}
void * resized_context_alloc(size_t size, void * prev_ptr)
{
return realloc(prev_ptr, size);
}
jerry_context_t* create_resized_context(size_t new_context_size_in_KB)
{
return jerry_create_context(new_context_size_in_KB * 1024, resized_context_alloc, _context_pointer);;
}
void enlarge_context(size_t new_context_size)
{
_context_pointer = create_resized_context(new_context_size);
}
jerry_context_t* _context_pointer;
main()
{
initial_context_create(1);
jerry_init(JERRY_INIT_MEM_STATS);
enlarge_context(2);
/* after that i should do something to reinitialize or edit enlarged _context_pointer,
because it doesn't in it's internal structure heap_size is 1024 (as set previously)
and i can not use enlarged allocated momery for the jerry_context_t (_context_pointer)
*/
/*
if i try to do jerry_init() again, of course all allocated memory is available, but i'm loosing all context data (such as ecma objects, and other previously created objects and variables before enlarging). Because before jerry_init() i should do jerry_cleanup()
*/
}
```
Is there any possibility to enlarge existing jerry_context_t without loosing all the data.
Thank You very much!

"jerryscript-project",
"jerryscript"
] | Hello,
I have my-own implementation of `setInterval(callback, interval)` written in C. When I run the below code, heap memory usage is increasing every callback call and finally system is stuck due to the lac of memory.
```js
setInterval(function () {
var t = millis();
console.log ("Current time is ", t, "ms.");
}, 100);
```
In our system, there is the main even loop. In the event loop, check interval time and call the callback using `jerry_call_function()`. Every callback call results memory consumption, but garbages are not collected even if `jerry_gc()` is called.
Like below code, heap memory is not increased if the callback is not generates garbages (like without `var t = millis();`).
```js
setInterval(function () {
console.log ("Current time is unknown");
}, 100);
```
Same phenomenon is observed in all cases that javascript callback function is called using `jerry_call_function()` from C code side. (Timer callback, UART data read callback, etc.)
For more info:
- [setInterval() implementation](https://github.com/kameleon-project/kameleon/blob/master/src/global.c#L317)
- [the code calling callback](https://github.com/kameleon-project/kameleon/blob/master/src/global.c#L282)
What I'm doing wrong? Any advices?
Thank you.

### Build platform
`Ubuntu 16.04.6 LTS (Linux 4.15.0-55-generic x86_64)`
### Build steps
```
python tools/build.py --debug --logging=on --line-info=on --error-messages=on --cpointer-32bit=on --mem-heap=2048 --profile=es2015-subset
```
### Test case
````
var NISLFuzzingFunc = function(d, c) {
var a = d.toPrecision(c);
};
var NISLParameter0 = 59246;
var NISLParameter1 = function(p) {

NISLFuzzingFunc(NISLParameter0, NISLParameter1);

### Execution steps
````
./jerryscript/build/bin/jerry testcase.js
````
### Output
````
````
### Expected behavior
Throw RangeError on line 2;
`RangeError: toPrecision argument must be between 1 and 21`
### Description:
I have manually calculated the test case above according to the definition of `Number.prototype.toPrecision` in the ES5.1. I think that jerryscript should throw RangeError exception in [step 8](http://www.ecma-international.org/ecma-262/5.1/index.html#sec-15.7.4.7).
```
8. If p < 1 or p > 21, throw a RangeError exception.
```
So, I suspect it is a bug of jerry.

] | Hello,
I want to make sure that `jerry_cleanup()` do not call free callback function assigned by `jerry_set_object_native_pointer()`.
My test procedure is:
1. Create a js object and then assign a native buffer to the object using `jerry_set_object_native_pointer()`.
2. Call `jerry_cleanup()`
3. The native buffer is not freed (free callback is not called).
I'm developing REPL and it supports `.reset` command to cleanup javascript context. It calls internally `jerry_cleanup()`. But the native buffers are not freed using `jerry_cleanup()`.
Is this intended for `jerry_cleanup()`?
If so, should I manage the native buffers internally and free them before calling `jerry_cleanup()`?.
Thanks in advance. | jerry_cleanup() do not call free callback assigned by jerry_set_object_native_pointer() | https://api.github.com/repos/jerryscript-project/jerryscript/issues/3172/comments | 5 | 2019-09-28T05:13:42Z | 2019-10-02T10:32:55Z | https://github.com/jerryscript-project/jerryscript/issues/3172 | 499,727,916 | 3,172 |

] | How to get information from const **jerry_value_t function_object** and **const jerry_value_t function_this** in code like below. I need to get the name of called external handler (some_handler) inside this handler, is it possible? Not to provide by arguments[], but to get from function_object for example.
Please help. And what is the structure of **function_object** and **function_this** to use them in a code.
#include <stdio.h>
#include "jerryscript.h"
static jerry_value_t
some_handler (const jerry_value_t function_object,
const jerry_value_t function_this,
const jerry_value_t arguments[],
const jerry_length_t arguments_count)
{
return jerry_create_undefined ();
}
int
main (void)
{
const jerry_char_t script[] = "call_handler('First arg');";
const jerry_length_t script_size = sizeof (script) - 1;
jerry_init (JERRY_INIT_EMPTY);
{
jerry_value_t global_object = jerry_get_global_object ();
jerry_value_t property_name_print = jerry_create_string ((const jerry_char_t *) "call_handler");
jerry_value_t property_value_func = jerry_create_external_function (print_handler);
jerry_value_t set_result = jerry_set_property (global_object, property_name_print, property_value_func);
jerry_release_value (set_result);
jerry_release_value (property_value_func);
jerry_release_value (property_name_print);
jerry_release_value (global_object);
}
jerry_value_t parsed_code = jerry_parse (NULL, 0, script, script_size, JERRY_PARSE_NO_OPTS);
if (!jerry_value_is_error (parsed_code))
{
jerry_value_t ret_value = jerry_run (parsed_code);
jerry_release_value (ret_value);
}
jerry_release_value (parsed_code);
jerry_cleanup ();
return 0;
}

"jerryscript-project",
"jerryscript"
] | I think that now that version 2.0 of JerryScript is out, we (as the maintainers/reviewers of the project) may acknowledge that our release strategy has been suboptimal. The project wasn't dead, as it was being continuously enhanced and extended. Yet, there had been no release for a period of almost 3 years. Yikes!
So, I propose to adopt two concepts from now on (i.e., should this motion pass):
- ["Release early, release often"](https://en.wikipedia.org/wiki/Release_early,_release_often) (*)
- [Semantic versioning](https://semver.org)
(* With the remark that "early" shouldn't and mustn't mean "buggy".)
So, a bit more thoughts about these ideas:
**Release Cadence**
For v2.0, we wanted to give our community a nice well-polished set of new features, APIs, etc. I don't think that we've failed, but it just took too long.
So, I propose to release a new version whenever a reasonable new feature or feature set is landed and stabilized in the project, even if we know that there will be related features implemented in the near (or not so near) future. Same goes for bug fixes and refactorings: even if the project is not extended feature-wise for some time but some useful internal refactorings or fixes are landed, we should come out with a new release.
I'd encourage all contributors to be pro-active. If they land some features in the project and think that it forms a nice "package" of improvement of the project, they should raise their voice and advocate a new release. (Maintainers should still have the final word about releases, but this could ensure that a release potential will not slip their attention.) A GitHub Issue seems to be a good way of proposing a new release, it will allow discussion between interested parties.
Should a motion for a new release pass, we'll have to ensure that it is in a reasonably stable state. CIs should be green. Known bugs should be fixed (as much as reasonably possible, at the discretion of the maintainers). Landing of features should be frozen for a short period to focus on stabilizing the release. (This should be some days or a week or so, when no new bugs pop up. This may depend on the volume of changes, but I'd prefer no overly long freezes. Just enough to make sure that we have a good level of confidence in the stability of the project.)
Some notes:
- This is NOT intended to mean a release after every commit. Of course not.
- No strict periodicity. We may have some months between some releases (e.g., if heavier features are being implemented), but we may also have days or weeks between some releases (e.g., if we only land fixes, or smaller features).
- Contributors may still open PRs and get reviews (modulo reviewers' availability) while the project is "frozen" before a new release.
- GitHub Milestones might be used to track work left, once we have agreed on the necessity of a new release.
**Semantic Versioning**
I really think that this would fit very well to the above-suggested frequent release strategy. We got some annoying bugs fixed: great, let's have a release x.y.Z+1! We have support for a new ES6 language keyword, or some new builtins got implemented: great, let's have a release x.Y+1.0! We have reworked the API: ok, let's have a major version bump. (Now, that shouldn't happen *too* often. But we shouldn't be overly afraid of it either. The right balance is the key.)
Some notes:
- We could say that we're already using semver. But actually, we aren't. We'd at least require a patch version number. (This also means that if/when we add the patch version macro to our headers, thereby we extend our API, so our next release will be version 2.1.0 right away.)
- We'll have to state clearly what constitutes our public API that falls under the jurisdiction of semver. (E.g., IMO, binary snapshots MUST NOT be considered as part of the public API. They are not for persistent storage between versions or between devices. A bump in the snapshot version SHOULD NOT imply a major version bump of the project.)
- To state the obvious: adding a new public API function does not require increasing the major version, it only bumps the minor one.
- We shouldn't be afraid of major version bumps, but it shouldn't happen on daily basis either. It has to be the maintainers' responsibility to have some foresight and plan breaking changes carefully. We have to offer some kind of API stability. (Foresight and planning also imply some kind of a feature roadmap. We'll have to have a (separate) discussion about that, too.)
- This wouldn't mean the maintenance of multiple major version or LTS branches, backporting bugfixes, etc. I don't think that we have the resources for that. Versions (that follow semver) remain tags on the master branch.
- We might also introduce a tag named "latest", which should always be moved to the latest release. (A good practice used by other projects out there.) (But this should be the only tag moving. Semver tags MUST stick.)
*Looking forward to comments.*
