The following script is made for testing branch coverage with all the test suites (`--jerry-test-suite --test262 --unittests --jerry-tests`), or with only one `.js` file.
https://github.com/matedabis/jerryscript/blob/gcov_coverage_tester/tests/gcov-tests/gcovtester.py
While measuring the branch coverage we dont count JERRY_ASSERT s. The results are measured by running all the test scripts, with the modifications in the PRs.
If you start working on a function, or open a PR, please leave a comment about it on this issue, so I can keep this issue up to date.

Heap Spray is a widely used payload-delivery technique, most JS engines nowadays integrate special mechanisms to mitigate it. Such as nozzle, bubble, etc. I recently came to conclusion that in JerryScript there are also a kind of mitigation to Heap-Spray, can you guys maybe confirm this and tell me what are the mechanisms being used in JerryScript to mitigate Heap-Spray?
If you refer me to any documentation that I can read considering this issue, I will also be very thankful.
Thank you so much. | Diskussion about the possibility of Heap-Spray in JerryScript: | https://api.github.com/repos/jerryscript-project/jerryscript/issues/2677/comments | 6 | 2019-01-07T00:14:33Z | 2019-01-08T17:45:27Z | https://github.com/jerryscript-project/jerryscript/issues/2677 | 396,310,056 | 2,677 |

# vulnerability
global buffer overflow
# test case
https://transfer.sh/9BXc6/test.js
# analysis
The global buffer overflow happened in the function `print_unhandled_exception`, here it tries to seek the correct position to print. However the size of `buffer` is limited to 1048576.
If we can make the `pos` over 1048576, the buffer overflow will be triggered.
```C
/* 2. seek and print */
while (buffer[pos] != '\0')
{
if (buffer[pos] == '\n')
{
curr_line++;
}
if (err_line < SYNTAX_ERROR_CONTEXT_SIZE
|| (err_line >= curr_line
&& (err_line - curr_line) <= SYNTAX_ERROR_CONTEXT_SIZE))
{
/* context must be printed */
is_printing_context = true;
}
if (curr_line > err_line)
{
break;
}
if (is_printing_context)
{
jerry_port_log (JERRY_LOG_LEVEL_ERROR, "%c", buffer[pos]);
}
pos++;
}

] | Hi, i want to extend jerryscript, and add `Number.isInteger` method, but i have encountered difficulties.
I learn `jerry-core/ecma/builtin-objects` codes, then i write these code:
```c
/* in lit-magic-strings.inc.h */
LIT_MAGIC_STRING_DEF (LIT_MAGIC_STRING_IS_NAN, "isNaN")
LIT_MAGIC_STRING_DEF (LIT_MAGIC_STRING_IS_INTEGER, "isInteger") // new
```
```c
/* in ecma-builtin-number.inc.h */
/* ECMA-262 v5, 15.7.3.1 */
OBJECT_VALUE (LIT_MAGIC_STRING_PROTOTYPE,
ECMA_BUILTIN_ID_NUMBER_PROTOTYPE,
ECMA_PROPERTY_FIXED)
ROUTINE (LIT_MAGIC_STRING_IS_INTEGER, ecma_builtin_number_object_is_integer, 0, 0) // new
```
```c
/* in ecma-builtin-number.c */
static ecma_value_t
ecma_builtin_number_object_is_integer (ecma_value_t this_arg /**< this argument */){
return ECMA_VALUE_UNDEFINED;
}
```
```c
/* in lit-magic-strings.ini */
LIT_MAGIC_STRING_IS_NAN = "isNaN"
LIT_MAGIC_STRING_IS_INTEGER = isInteger
```
finally, i compile my work, and run bin/jerry and example code, i got undefined.
```javascript
console.log(Number.isInteger) // undefined
```
But when i replace `LIT_MAGIC_STRING_IS_INTEGER` to `LIT_MAGIC_STRING_IS_NAN`, and run example code, it workes
```javascript
console.log(Number.isNaN) // not undefined
```
I don't know why I got the error. I didn't see the relevant documentation. I hope I can solve this problem for you. Thank you.

] | When I use scientific notation to assign a value to a variable, I find that in some specific cases, Jerry introduces errors, causing subsequent operations to fail.
The common feature of these specific numbers is that the 5th decimal place is odd and the exponent is 21, just like `1.00001e+21`, `1.0003e+21`, etc. When the assignment is over, the value of the variable introduces a small error.
For example:
```javascript
var num = 1.00517e+21;
print(num);
// print(String(num));
```
The result of the program running is `1.0051700000000001e+21`.
A similar operation has no errors on `nodejs`, `v8`, or `SpiderMonkey`.
After debugging analysis, it is found that the numerical value literal has been introduced into the error after being processed by the `ecma_utf8_string_to_number()` function.
I think there is a problem here, please fix it or or give a relevant explanation, thank you. | An error occurred when using scientific notation | https://api.github.com/repos/jerryscript-project/jerryscript/issues/2638/comments | 5 | 2018-12-12T02:22:57Z | 2019-01-23T03:28:51Z | https://github.com/jerryscript-project/jerryscript/issues/2638 | 390,037,261 | 2,638 |

] | Recording a scenario from #2606
> [A] failure was found when debugging IoT.js with static snapshots turned on, if an error was thrown an assertion failure was caused. The reason is the frame context's `bytecode_header_p` pointer was not a heap pointer. The `jerry_debugger_breakpoint_hit` function tries to set a compressed pointer which points to `bytecode_header_p` with the `JMEM_CP_SET_NON_NULL_POINTER` macro, which has an assertion that requires the above mentioned `bytecode_header_p` to be a heap pointer, which is obviously not.
> [Creating a a JerryScript-only test environment is n]ot a trivial task. You need a unit test which creates such an environment, and you also need the python debugger to do debugging. Hence it needs a new infrastructure basically, where instead of a .js, a binary is run by the debugger tester driver. | Add test environment for debugging with static snapshots enabled | https://api.github.com/repos/jerryscript-project/jerryscript/issues/2637/comments | 0 | 2018-12-11T17:45:57Z | 2018-12-11T17:45:57Z | https://github.com/jerryscript-project/jerryscript/issues/2637 | 389,879,572 | 2,637 |

The reason is that, in future we might have better options that libc dependencies removed for some how OS (w/- libc) or libdl-in-use anyway.

This is Qihoo360 CodeSafe Team, we found a suspicious unsigned integer wrap issue, see
https://github.com/jerryscript-project/jerryscript/blob/3c1d0e61002c5424d2b882a8044b75a11c0dd58c/jerry-core/ecma/base/ecma-helpers-number.c#L539. At line 539, when the program execute `fraction--`, there is a chance that the value of `fraction` is 0. For the condition expression at line 531, if `fraction` and `biased_exp` are all zero, else branch will be chosen.
Since I not familiar with `jerryscript`, I am not sure `fraction` and `biased_exp` are absolutely independent, that is can them be zero at the same time?

"jerryscript-project",
"jerryscript"
] | Folks,
tl;dr: I need to "un-pop" the argument stack -- go to the last paragraph (starting with "Finally,...") for my suggested addition to the `jerryx_arg` routines...
I'm working extensively with the `jerryx_arg` routines/types, and I've hit a snag:
I need to query the argument stack without changing it. For example, I might be expecting a parameter that is _either_ a number or a string.
Thus, I'd like to do something like (simplified, not accurate :-) :
```
result = jerryx_arg_number(...)
if (jerry_value_is_error(result))
result = jerryx_arg_string(...)
```
I could write my own "`jerryx_arg_number_or_string`", but the permutations of all the arguments are too numerous, it'd be a copy of a whole lot of code that already exists, and I don't get the continuity of behavior with my own code -- specifically, it's not easy to mimic the behavior of the `JERRYX_ARG_COERCE` flag, so a simple call to jerryx_arg_number vs my own homegrown version of the above code would likely give different results given certain inputs.
One solution would be to give more power to the `JERRYX_ARG_OPTIONAL` flag -- if a type check fails, that `jerryx_arg_*` function would not pop the stack. I dislike that solution, b/c it would mean overloading the meaning of that flag.
A second solution would be to add a flag to all of the `jerryx_arg_*` functions to specify whether the stack top should be popped on failure. We could add a new enum type like jerry_arg_coerce_t, _etc_., to control this behavior. I think this solution has the some merit: it keeps the minimalistic interface of the `jerryx_arg_*` functions and lets us maintain the current behavior as the default. Its downside is that it adds some logic to the `jerryx_arg_*` routines...
To implement this solution, I propose adding a new enum type in the extension code, the documentation for which would read as follows:
> **jerryx_arg_pop_on_failure_t**
> Enum that indicates whether a failed transformation attempt modifies the stack.
> - `JERRYX_ARG_POP_ON_FAILURE` -- calling the transform has the effect of popping the top value off of the argument stack
> - `JERRYX_ARG_DO_NOT_POP_ON_FAILURE` -- if the transform returns an error, the stack is left unchanged
Finally, the solution I'd like to propose is to add a new call to the custom-validation support routines that would let us "restore" the value just popped. This solution would normally not work, but in our case, "pop" just moves a pointer through an array, so like we increment the pointer on a pop, we decrement that pointer on a restore. I have written this code (and use it now in my work), and it is as follows:
```
/**
* Restore the previous JS argument from the iterator.
* It will change the index and js_arg_p value in the iterator.
*
* @return the restored (now current) JS argument.
*/
jerry_value_t
jerryx_arg_js_iterator_restore (jerryx_arg_js_iterator_t *js_arg_iter_p) /**< the JS arg iterator */
{
if (js_arg_iter_p->js_arg_idx == 0)
return jerry_create_undefined();
else
{
--js_arg_iter_p->js_arg_idx;
--js_arg_iter_p->js_arg_p;
return *js_arg_iter_p->js_arg_p;
}
} /* jerryx_arg_js_iterator_restore */
```
Discussion?
Thanks,
Tim

Tried a few things including updating mbed-os from what is included by jerryscript but no luck. Any thoughts on a fix? Tends to be difficult to fix simple things like missing include dirs with all the magic Mbed CLI does and now with another layer of gulp, I thought I'd ask before trying to dig in further.

] | Folks,
I'm stymied, and I'd appreciate a tutorial...
I'm trying to use the jerryx_arg* functions to do parameter checking --the example for jerryx_arg_array shows how to get a static array (e.g., if you expected a parameter that looked like: [int, float, string]), but I'm looking to validate a parameter that is an arbitrarily long array of \<Type>s (e.g., in C, an int[]).
I'm writing my own jerryx_arg_transform_funct_t: the first thing I'll do is pop the element off the args list, which returns a jerry_value_t, but my mental model is that it should instead return an array of jerryx_arg_t's which I'll then need to call jerryx_arg_\<Type> over to build up my array.
...and there's where I'm stuck. Help is most(!) appreciated!
Tim
P.S. I've already written one transform_func_t for floats, as I needed to encapsulate the type conversion from double (which is provided by jerryx_arg_number, which requires a double*), which I've shown below; any comments would be likewise appreciated:
```
#define jerryx_arg_float(x, z) \
jerryx_arg_custom(x, \
(uintptr_t)&((uintptr_t []){(uintptr_t)JERRYX_ARG_COERCE, \
(uintptr_t)z}), \
jerryx_arg_to_float)
// the transform function for floating-point numbers is defined only
// for doubles, so we need a wrapper that will call the version for
// doubles and then convert that value to a float
jerry_value_t jerryx_arg_to_float(jerryx_arg_js_iterator_t *js_arg_iter_p,
const jerryx_arg_t *c_arg_p)
{
double intermediate_result = 0.0;
uintptr_t *extra_info = (uintptr_t*)(c_arg_p->extra_info);
jerryx_arg_t get_double = jerryx_arg_number(&intermediate_result,
extra_info[0],
extra_info[1]);
jerry_value_t convert_to_double_result =
get_double.func(js_arg_iter_p, &get_double);
if (!jerry_value_is_error(convert_to_double_result))
*((float*)(c_arg_p->dest)) = (float)intermediate_result;
return convert_to_double_result;
} /* jerryx_arg_to_float */

"jerryscript-project",
"jerryscript"
] | Folks,
Disclaimer: if I've misunderstood something in my explanation: a) mea culpa; feel free to beat me up :-), and b) please explain the truth not only to me, but maybe also include the explanation in the docs...
The jerry_object_native_info_t structure contains exactly one field, a pointer to the function that the garbage collector calls to free the native object. A crude form of type checking is performed every time the native object is accessed: the address of the native_info_t structure is recorded when the native object is created, and subsequent accesses include a check against this address.
...this design has bitten me, but instead of trying to explain the vagaries of separate compilation and const pointers (I'll gladly do so, but it'll be long and tedious... :-), I'd rather make the case to change this from a design perspective:
In general, a structure with only one field does not need to exist -- the field can just be used as it is; as a simple example: imagine if every integer were a struct containing a single int...
Of course, some systems do exactly that: wrap a struct around simple data types, but they do so for really specific reasons, none of which(?) apply to the native-object code: the "type checking" is only against a constant address of a structure -- probing the system indicates that the contents of the structure aren't even accessed; but even if they are, the only thing in the structure is a function pointer that, by definition, is itself a constant address.
Can we fix this so that the native-object code just makes sure that the free_cb function remains unchanged? (That is, wherever we now send in a pointer to the native_info_t struct, instead send in the free_cb-function pointer instead.)
(No need to read this paragraph is you're already convinced :-) -- The current abstraction is excellent, in that it says: every time you access this otherwise-opaque pointer, make sure it's the right kind of thing by checking against a type signature (which happens to just be the pointer used to free the object). If we implement my proposed change, the abstraction becomes: every time you access this pointer, make sure the guy accessing it knows that a particular function is the function used to free it -- yuck. So to maintain the abstraction with the native_object_t struct, we should not check the address of the struct, but, rather, do a field-by-field comparison of the structs. That way, two otherwise identical structs would match. This, obviously, would require more processing, but would maintain the nice design.
Thanks,
Tim
P.S. This is not a particularly urgent issue -- careful #def'ing solved my specific problem, but it was a little tricky to get right, and the docs aren't very helpful -- thus this suggestion to simplify the design. | Scrap the jerry_object_native_info_t type and just use jerry_object_native_free_callback_t for native objects | https://api.github.com/repos/jerryscript-project/jerryscript/issues/2562/comments | 3 | 2018-10-17T16:54:30Z | 2019-10-18T11:40:09Z | https://github.com/jerryscript-project/jerryscript/issues/2562 | 371,174,060 | 2,562 |

] | Hi,
We are seeing some behavior which we didn't expect when processing an object (jerry_value_t) in c, returned from a javascript function. I am not sure if this is normal behavior, as I am not very familiar with Javascript. Any comments or responses to shed some light on this would be appreciated.
We parse and run the following script:
`function(input) {
var x = 0;
var a = [x];
return { "name_x" : a };
}";`
Then, in c, we extract the array `a` and check it's type and size using: `jerry_value_is_array(a)` and `jerry_get_array_length(a)`. These return `true` and `1`, as expected.
We then call `jerry_get_property_by_index(a, 0)`. This call returns NULL, which is unexpected. We were expecting the call to return an object containing a float value of 0.
Is this normal? | jerry_get_property_by_index returns NULL when array item initialized with zero | https://api.github.com/repos/jerryscript-project/jerryscript/issues/2552/comments | 5 | 2018-10-04T19:16:34Z | 2018-10-09T20:04:27Z | https://github.com/jerryscript-project/jerryscript/issues/2552 | 366,932,110 | 2,552 |

] | Folks,
I apologize if I'm being obtuse, but I'm stuck:
This morning, I cloned a clean repo and rebuilt a unix version of the repl (using jerry-main/main-unix.c).
The following Javascript:
`var x = new ArrayBuffer(128);`
...produces:
`Script Error: ReferenceError`
...I've also tried to use the API to create my own ArrayBuffer. In the following code, I've created two objects, one a long value (as a control) and one an ArrayBuffer -- the code is the same for both, with the exception of the creation of the actual data object -- and I've inserted the code into the main routine before the repl starts:
```
jerry_value_t new_thing = jerry_create_string((jerry_char_t *)"new_thing");
jerry_value_t new_thing2 = jerry_create_string((jerry_char_t *)"new_thing2");
jerry_value_t new_ab = jerry_create_arraybuffer(10);
jerry_value_t new_num = jerry_create_number(2.0);
jerry_value_t global_object = jerry_get_global_object();
jerry_set_property(global_object, new_thing, new_ab);
jerry_set_property(global_object, new_thing2, new_num);
jerry_release_value(global_object);
```
...and inside the repl:
```
jerry> new_thing
Script Error: ReferenceError
jerry> new_thing2
2
```
...so what am I doing wrong?
Thanks!
Tim

Compile like this:
python tools/build.py --error-messages=ON --line-info=ON --mem-heap 9 --debug
Then there will be an assertion fail to indicate the pointer to be freed is not pointing to the heap.
I think it's the double free of literal causing such a isuue.
First free at "js-parser.c" line 206,which is called by function "parser_post_processing" at line 1496
After error occurs at line 1726 for "out of memroy" error,the second free will happen at line 2416-->line 2413-->"common.c" line 42
Of course,when the second free happens,the address passed to function "jmem_heap_free_block" is totally wrong as it was changed at "js-parser.c" line 201,which is the reason why the assertion fails.

] | The engine's code base has lots of macro guards, making it well-configurable. However, these macros grew somewhat organically and got named as `CONFIG_{EN,DIS}ABLE_xxx`, `CONFIG_xxx`, `{EN,DIS}ABLE_xxx`, `JERRY_{EN,DIS}ABLE_xxx`, `JERRY_xxx`, or `modulename_xxx`. Quite a mix. Moreover, right now it is encoded in some of the names of the macros whether they are enabled/disabled by default (but not in all of the names). And boolean configuration macros make their effect based on whether they are defined or not, while the rest carry their meaning via their content.
I propose to consolidate the configuration macros name and value wise, as shown in the table below:

Notes:
- Alternatively, the prefix of all configuration macros might be `JERRY_CONFIG_` instead of `JERRY_`.
- There is one 'boolean' config macro that cannot/shouldn't be rewritten to 0/1: `JERRY_NDEBUG`. Traditionally, the semantics of an `NDEBUG` that macro is defined/not-defined everywhere.
- I haven't listed `JERRY_GET_CURRENT_CONTEXT` above as I hope it goes away soon (see #2512).
- I find the value set of the existing `CONFIG_ECMA_NUMBER_TYPE` (1/2) somewhat counterintuitive. Thus, I've proposed to enable string values (float32,float64,float,double). I think that approach could be managed by some preprocessor magic (using `##` concatenation).
Some additionally observed problems:
- Not all of the above configuration options are available via the python build script and/or cmake options (i.e., they have to be passed as compiler arguments).
- Not all of the above configuration options are available as feature enum labels of the engine, so they are not queryable at run-time. (Among others,) this leads to leaking macro usage into users of the engine (e.g., jerry-main, jerry-ext, or jerry-port using jerry-core macros in `#if`s).
- Not all of the above macros are documented at all.
- Configuration macro names and cmake option names are quite unaligned, which adds one more layer to the naming mix.
Foreseen work items:
- Refactoring of the jerry-core code base to rename the macros and guard code blocks based on macro values.
- Follow up in the cmake build system to pass macros with values to the compiler.
- Follow up in the python build tool to pass the right cmake options.
- Follow up in the lit-magic-strings.inc.h generator tool (gen-magic-strings.py).
- Follow up in jerry-main, jerry-port, and jerry-ext, to ensure that 'leaked' macros are used according to the new semantics.
- Follow up in targets to adapt the builds (mostly: with which options cmake is called).
I think such a rework would help code quality, clarity, and maintainability. I'm also volunteering to work on this, but I'd like to get some feedback first so that it's not done in vain. So, please, let me know what you think about this in general, or about any of the details (e.g., preferred config macro names, values, etc.)
PS: I know that we have had quite some discussion about config macros before, even heated ones. I'm not afraid of putting the topic on the table again, believing that it may make the project better. | Consolidate configuration macros | https://api.github.com/repos/jerryscript-project/jerryscript/issues/2520/comments | 5 | 2018-09-11T18:57:27Z | 2019-10-18T11:37:26Z | https://github.com/jerryscript-project/jerryscript/issues/2520 | 359,177,527 | 2,520 |

SUMMARY: AddressSanitizer: stack-overflow ../../../../libsanitizer/asan/asan_interceptors.cc:39 in QuickCheckForUnpoisonedRegion
==11344==ABORTING
```
Immediate cause:
Recursion in ecma-regexp-object.c is not properly used. Depth of the recursion is controlled only by the structure of a regular expression, which may result in JerryScript running out of stack space.
This might lead to DoS attack if an attacker is able to construct arbitrary regular expressions.
This seems to be a difficult bug to fix. Possible solutions could include checking stack limits, breaking recursion which is deeper than predefined value or refactoring the code to not use recursion.
Please note, that because this crash is a result of the program running out of stack memory, this exact input may not produce the same result across different systems. To easier reproduce this issue one may want to limit stack size (using for example `ulimit`).
This issue looks similar to https://github.com/jerryscript-project/jerryscript/issues/2190, but the problem occurs in a different code line, confirming that the design of the function in question is not properly implemented. | Uncontrolled recursion in re_match_regexp | https://api.github.com/repos/jerryscript-project/jerryscript/issues/2448/comments | 0 | 2018-08-07T08:00:14Z | 2019-01-17T19:16:50Z | https://github.com/jerryscript-project/jerryscript/issues/2448 | 348,209,807 | 2,448 |

```
- Immediate cause:
It seems that this bug is caused by triggering undefined behavior at jerry-core/ecma/builtin-objects/typedarray/ecma-builtin-typedarray-prototype.c:598. The second passed argument is NULL. This causes NULL dereference and allows GCC to optimize out subsequent checks for NULL. This further causes writing to null pointer, which results in a segmentation fault. Note, that because this bug occurs due to gcc optimizing out a check for NULL, this may not be reproducible with a debug build.
Please confirm if you can reproduce this issue.

I'm doing my open source project using JerryScript over one and a half year. Sometimes I need to upgrade JerryScript from the git code base.
But, I'm worry about integrating just most recent commits, not official release. There is no official release since Sep. 2016 (v1.0). And, it is also hard to identify what are actually changed because there is no "Release Notes".
So I would like to suggest more frequent releases (about monthly - recommend agile development process like [scrum](https://en.wikipedia.org/wiki/Scrum_(software_development))) with fine-grained versions like "1.0.3", "1.1.0", "1.2.0", "1.3.0" and so forth ([semver](https://semver.org/) would be great).
This would be very helpful for the many JerryScript fans :)

] | Hello,
I'm trying to get Jerryscript running on an ARM device but I'm running into a linker problem I can't seem to figure it out. I've added a toolchain file named toolchain_gba_arm7tdmi and it looks like:
```cmake
set(DEVKITARM $ENV{DEVKITARM})
set(DEVKITPRO $ENV{DEVKITPRO})
if(DEVKITPRO)
message(FATAL_ERROR "DEVKITPRO environment variable not set")
endif()
if(NOT DEVKITARM)
message(FATAL_ERROR "DEVKITARM environment variable not set")
endif()
set(CMAKE_SYSTEM_NAME GBA)
set(CMAKE_SYSTEM_PROCESSOR arm7)
set(FLAGS_COMMON_ARCH -mthumb -mtune=arm7tdmi -mcpu=arm7tdmi -fomit-frame-pointer -Wno-packed-bitfield-compat -ffast-math)
set(CMAKE_C_COMPILER ${DEVKITARM}/bin/arm-none-eabi-gcc)
set(CMAKE_C_COMPILER_WORKS TRUE)
```
As you can see, it uses the `arm-none-eabi-gcc` compiler. When I build Jerryscript I get no compilation errors, but I've noticed during the linking steps I get these messages:
```
[ 85%] Linking C static library ../lib/libjerry-core.a
warning: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ranlib: warning for library: ../lib/libjerry-core.a the table of contents is empty (no object file members in the library define global symbols)
[ 85%] Built target jerry-core
```
I'm only taking a guess here, but I think it's not using the ARM linker and instead using Xcode. Before this message however, during the start of the build process, I get a cmake warning:
```
CMake Warning:
Manually-specified variables were not used by the project:
CMAKE_TOOLCHAIN_FILE
```
I'm assuming this is why I get undefined reference when I link Jerryscript with my main project. This is how I build Jerryscript:
```

--cpointer-32bit=off --mem-heap=256 \
--toolchain=$(CURDIR)/jerryscript/cmake/toolchain_gba_arm7tdmi.cmake \

###### Description:
The test case below converts an array to JSON string. However, (probably because of the unicode characters) the last object's last field (`fz_return`) will be somehow truncated, resulting an incorrect JSON string.
###### Test case:
```javascript
print(JSON.stringify([
{"dddddd":"ccccccccccccc","bbbbb":225,"vvvvv":{"aaaaaaa":"call","ffffffff":["w2\u1D306A"],"fz_return":0}},
{"dddddd":"ccccccccccccc","bbbbb":225,"vvvvv":{"aaaaaaa":"call","ffffffff":["\uD834\uDF06"],"fz_return":0}},
{"vvvvv":{"aaaaaaa":"call","fffffffff":["D"],"fz_return":0}}]))
```
###### Expected output:
```javascript
[{"dddddd":"ccccccccccccc","bbbbb":225,"vvvvv":{"aaaaaaa":"call","ffffffff":["w2ᴰ6A"],"fz_return":0}},{"dddddd":"ccccccccccccc","bbbbb":225,"vvvvv":{"aaaaaaa":"call","ffffffff":["𝌆"],"fz_return":0}},{"vvvvv":{"aaaaaaa":"call","fffffffff":["D"],"fz_return":0}}]
```
###### Actual output:
```javascript
[{"dddddd":"ccccccccccccc","bbbbb":225,"vvvvv":{"aaaaaaa":"call","ffffffff":["w2ᴰ6A"],"fz_return":0}},{"dddddd":"ccccccccccccc","bbbbb":225,"vvvvv":{"aaaaaaa":"call","ffffffff":["������"],"fz_return":0}},{"vvvvv":{"aaaaaaa":"call","fffffffff":["D"],"fz_r:0}}]

"jerryscript-project",

] | I was wondering if there are any side effects besides increased memory usage by using uncompressed pointer(passing `--cpointer-32bit` as a build option).
My main concern is according to the [data representation](https://github.com/jerryscript-project/jerryscript/blob/master/docs/04.INTERNALS.md#data-representation) section of the docs:
the structure can only hold at max 29 bit pointers.

[
"jerryscript-project",
"jerryscript"
] | So I was trying to debug my last [issue](https://github.com/jerryscript-project/jerryscript/issues/2365) and I ran into what I think its a bug.
***Explanation***
* `jerry_create_external_function_object` calls [`ecma_op_create_external_function_object `](https://github.com/jerryscript-project/jerryscript/blob/64b16bf190cc1965549c395f5fe9513ef3cd74f4/jerry-core/ecma/operations/ecma-function-object.c#L257).
* If you look at [`ecma_op_create_external_function_object`](https://github.com/jerryscript-project/jerryscript/blob/64b16bf190cc1965549c395f5fe9513ef3cd74f4/jerry-core/ecma/operations/ecma-function-object.c#L257), it sets the type flag of the function object by calling [`ecma_create_object`](https://github.com/jerryscript-project/jerryscript/blob/47794512846d74a1255016ea087ab2003d1f1d6b/jerry-core/ecma/base/ecma-helpers.c#L76) with `ECMA_OBJECT_TYPE_EXTERNAL_FUNCTION`.
* You can check the flag before `ecma_op_create_external_function_object` by logging with `printf("%x\n", function_obj_p->type_flags_refs);` and it will print `0x63`.
* Now `jerry_create_external_function_object` will return the newly created function object and the user will call [`jerry_set_property`](https://github.com/jerryscript-project/jerryscript/blob/ac9fce1d8d5a8eb821525f09ef1607e4643e14f3/jerry-core/api/jerry.c#L1929) to register the external function.
* If you log out the type flag again in [`jerry_set_property`](https://github.com/jerryscript-project/jerryscript/blob/ac9fce1d8d5a8eb821525f09ef1607e4643e14f3/jerry-core/api/jerry.c#L1929) using `printf("%x", ecma_get_object_from_value (obj_value)->type_flags_refs)`, it will log out `0x60`. **So it lost its type flag somehow**.
*I checked the `prop_name_val` by converting it to `char *` then `strcmp` to make sure I was actually logging the newly created external function object.* | external function type flag is lost after returning from create_external_function | https://api.github.com/repos/jerryscript-project/jerryscript/issues/2366/comments | 2 | 2018-05-30T23:06:56Z | 2018-05-31T12:09:05Z | https://github.com/jerryscript-project/jerryscript/issues/2366 | 327,930,149 | 2,366 |

] | I have noticed everytime JS calls an external C function the `LCACHE` will miss.
Testing method:
I looped an external C call 10000 times and `LCACHE` missed exactly 20000 times. (MISS when ecma_lcache_lookup returns NULL)
This is quite a performance hit. Calling an empty external C function is 10% faster(77282 cycles vs 88476 cycles) with `LCACHE` completely disabled.
Can anyone confirm this? | LCACHE misses for every native C function call | https://api.github.com/repos/jerryscript-project/jerryscript/issues/2365/comments | 6 | 2018-05-29T19:21:34Z | 2019-01-02T10:00:31Z | https://github.com/jerryscript-project/jerryscript/issues/2365 | 327,453,884 | 2,365 |

It was initially developed to support the Mbed OS 3 branch of Mbed which was discontinued 18 Months ago and is no longer supported by Arm.
Retiring this target would give us the opportunity to entirely concentrate on the Mbed OS 5 target.
It's understood that users may still be interested in the original Mbed port, so please let us know if this is the case.

"jerryscript-project",
"jerryscript"
] | There is an ongoing work of changing "error flags" to "error values". "error values" are primary values such as "null", "number", but they exist only on Jerry API level. Therefore JS do not need handle them at all.
Error values are designed to be return values, not arguments (no change here). Hence any API or C callback function can return with an error value, but the returned error value cannot be passed to other functions except a few error management functions and `jerry_release`. The value can be extracted from the error by `jerry_get_error_from_value`. The `jerry_create_error_from_value` creates an error value using the non-error value argument. For aborts, there will be a `jerry_create_abort_from_value`. Abort is the same as errors, except they are not caught by JS, and can only created by API or the debugger. `jerry_is_error_value` tells if the value is an error. Abort is considered a special variant of error. So everything true to an error is also true to an abort, but there is a special create/is_abort function to tell the difference.
This is the current plan now. We are open to feedback. | Discussing error management | https://api.github.com/repos/jerryscript-project/jerryscript/issues/2318/comments | 1 | 2018-05-09T08:33:28Z | 2019-08-04T10:54:18Z | https://github.com/jerryscript-project/jerryscript/issues/2318 | 321,478,923 | 2,318 |

] | Hello,
I'm writing code that should work as the following from the JS side:
```js
x.y.fn('foo')
.then(v => console.log(v))
.catch(error => console.err(err));
```
Don't worry about what happens when the promise is resolved, my problem is when I reject the promise. Currently, I want to reject the promise and pass an error object to the catch handler when the supplied string to `fn` is not a special value.
The code I have looks like the following:
```c
jerry_value_t returned_promise = jerry_create_promise();
if (should_reject_promise) {
jerry_value_t error = jerry_create_error(...);
jerry_value_t result = jerry_resolve_or_reject_promise(returned_promise, error, false);
DEBUG_LOG("RESULT STATUS: %d", jerry_get_error_type(result));
// If something went wrong rejecting the promise, error out.
if (jerry_value_has_error_flag(result)) {
jerry_release_value(returned_promise);
jerry_release_value(error);
return result;
}
// No issue rejecting the promise so return it.
jerry_release_value(result);
jerry_release_value(error);
return returned_promise;
}
// ...
```
When I run my JS code I get the following error:
```
ICE: Unreachable control path at .../vendor/jerryscript/jerry-core/ecma/base/ecma-helpers-value.c(ecma_copy_value):Error: ERR_FAILED_INTERNAL_ASSERTION
Fatal Jerryscript Error: ERR_FAILED_INTERNAL_ASSERTION
```
Am I not allowed to pass an error object in? Documentation doesn't seem to say. Any help would be appreciated! Thanks.

] | Folks,
When I am done using the interpreter, I would like a way to clean up (in case I want to start a new instance of the interpreter, for example) that doesn't complain about un-free'd jerry_value_t values, etc.
It's useful sometimes to have jerry_cleanup complain to tell me when I've got a leak, but there are times when I just want it to clean up everything and exit, without lecturing :-) me.
...is this possible now, can we add a flag to jerry_cleanup ("quiet"), or is there some deep technical issue I don't understand that precludes this functionality?
Thanks,
Tim
As an example, I'd like to write code like:
```
main()
{
for (i = 0; i < forever; i++)
{
jerry_init();
...do some stuff, leak pointers/memory all over the interpreter, etc.
jerry_cleanup("quiet"); /* reset the world sans error messages/exceptions/etc. */
}
} /* main */

Otherwise there can only be a single optional argument. Another consequence is that `jerryx_arg_transform_optional` does not work together with `jerryx_arg_transform_object_properties` because the iterator does not get advanced when an optional arg is `undefined`...
It looks like the unit test doesn't have either of these scenarios as a test case.
@jiangzidong do you agree this is a bug?
