] | This [Travis build](https://travis-ci.org/jerryscript-project/jerryscript/jobs/361777717) failed for me while trying to download the Zephyr SDK. I wonder if you're seeing that a lot? I used to have that problem in ZJS but I solved it with Travis caching in this [pull request](https://github.com/intel/zephyr.js/commit/ce313765b829108a308edaf675d390752f29c80f).
If it had been that simple here I would have tried it and submitted a PR right away, but it looks like you'd need to edit `zephyr/Makefile.travis` as well as `.travis.yml` and I don't have time at the moment to look into this, so I wanted to make a note of it.
This also has the benefit of skipping the download most of the time, speeding up the Travis build a lot. So basically, if you do it like I did, you'd cache some directory that holds the SDK and then check to see if it already contains the right version before you bother to download it with `wget` in the Makefile.
I'd also suggest parameterizing the Zephyr build version like we've done in ZJS to make it easier to update.
I intend to look at this someday myself but in case someone cares to beat me to it, here you go. :) | Suggest caching Zephyr SDK for Travis speed / success improvement | https://api.github.com/repos/jerryscript-project/jerryscript/issues/2268/comments | 3 | 2018-04-03T20:45:06Z | 2019-01-12T11:21:50Z | https://github.com/jerryscript-project/jerryscript/issues/2268 | 310,992,130 | 2,268 |

] | I realize this is not a JerryScript specific question, but I was wondering what people's approaches are towards dealing with strings from JS when they have a `\u0000` unicode code point(s) in them. This ends up being encoded as a `0x00` byte, which happens to be the "terminator" of a C string as well.
I can imagine this being a source of bugs, esp. if assumptions are made in the C code w.r.t. the length given by `jerry_get_(utf8_)string_length()` vs `strlen()`/`strlen_s()`.
Some approaches I can think of to deal with this:
- Don't use anything from `<string.h>`, instead use a proper utf8 library to deal with strings that only takes in string data in the form of a pointer + length.
- Truncate: just use the first `0x00` as the end and wipe all data after it just to be sure.

Usually, stack-overflow issues happen due to recursive js calls which is expected.
However, this test case doesn't contain any explicit recursion, so it may uncover a real issue.

```
typedef struct {

} FooBar;
static void free_ctx_cb(void *native_p) {
FooBar *ctx = (FooBar *) native_p;
jerry_release_value(ctx->val);

ctx->val = jerry_acquire_value(this_val);
jerry_set_object_native_pointer(obj, (void *) ctx, &native_info);
return obj;
}
```
To finish my program I call `jerry_cleanup()`. This triggers garbage collection, which causes `free_ctx_cb()` to be run. `free_ctx_cb()` decrements the ref count on the variable, but the garbage collection alg doesn't seem to be aware of this new deref, so I get the following: `jerry_assert_fail(assertion="JERRY_CONTEXT (jmem_heap_allocated_size) == 0")`
To work around this I have to call `jerry_gc(); jerry_cleanup();`, but as you can imagine that only works for 1 layer. There could hypothetically be multiple more layers.
Am I using the APIs incorrectly, or should there be another loop in the garbage collection algorithm to pick up any new objects with a ref count of 0? | Garbage collection doesn't free values released during garbage collection (via native pointers) | https://api.github.com/repos/jerryscript-project/jerryscript/issues/2253/comments | 10 | 2018-03-26T14:43:43Z | 2020-06-12T13:51:30Z | https://github.com/jerryscript-project/jerryscript/issues/2253 | 308,602,625 | 2,253 |

Hello I build JerryScript with CodeBlocks for Windows and Linux and Raspberry PI 32/ 64-bit
With support for double "-d" and float "-f" so the resulting libs are:
JerryScript-32-f.dll, JerryScript-32-d.dll, JerryScript-64-f.dll, JerryScript-64-d.dll
libJerryScript-32-f.so, libJerryScript-32-d.so, libJerryScript-64-f.so, libJerryScript-64-d.so
Of course for the FLOAT32 build I disabled the JS date functionality and it works all so far.
But I wonder me that jerry_create_value and jerry_get_value are hard coded for "double" ?
I mean if I build JerryScript for my retro computer I have only float my retro compiler
don't have the data type double at all.
So why does JerryScript use double if
(CONFIG_ECMA_NUMBER_TYPE == CONFIG_ECMA_NUMBER_FLOAT32)
are defined ?
Thank you DJ

] | The current debugger only works on Linux's BSD socket, I am trying to get the debugger to work on Zephyr since it recently added BSD socket support. However, it has slightly different headers for using the socket library and also it currently only supports a subset of the API. It would be nice if we can decouple all those socket APIs like accept(), send(), recv() and sleep() into jerry_port APIs as they can be platform-dependent. Are there any plans to add debugger support for other platforms?
Here's the working here, basically I replaced the debugger-ws.c with my own debugger-ws-zephyr.c when building for Zephyr:

What we should do before that is reworking the API. Some ideas:
- delete obsolote functions
- rework error flag to be an error value (error can only be a result of something, and cannot be used as input except unboxing its value). | JerryScript 2.0 | https://api.github.com/repos/jerryscript-project/jerryscript/issues/2213/comments | 23 | 2018-02-20T07:21:14Z | 2019-08-04T10:49:26Z | https://github.com/jerryscript-project/jerryscript/issues/2213 | 298,493,894 | 2,213 |

[
"jerryscript-project",
"jerryscript"
] | Right now there are [2 debugger client implementations]: 1) a CLI client written in python 2) a browser based client written in HTML/JS.
Both re-implement similar thing. Both are written in ways that make it hard to reuse pieces of the code in other contexts, mainly because they are written as large, monolithic blobs of code.
During the last [JerryScript Workshop] in the Fall of 2017, we talked about the desire to be able to leverage existing JS debugger infastructure, to avoid re-inventing the wheel and re-creating the functionality that already exists in existing debugger clients such as IDEs.
I think the first stepping stone towards that goal is to rewrite/refactor the existing debugger client code into a re-usable library that other tools can be built on top of (a CLI interface being one of them).
In terms of language of choice, we would like write this library in TypeScript because of the many advantages a typed language gives and because it transpiles into JS and can therefore easily be run inside Node.js (for CLI tooling), inside a browser or even inside JerryScript itself ;)
When written in TS/JS, this libary can be published to npm, to make it easy to consume the library as well.
I imagine to build this library alongside the existing clients and as soon as the library is "at par" with the existing clients, rework the existing clients to make use of the library. At that point, the `jerry-client-ws.py` would be replaced with a tiny Node.js program that wraps the libary and implements the CLI.
## Questions
### What does the core team think of this idea?
### Are there any major changes / extensions to the protocol planned?
### Where would the sources of the library live / what is the development repo?
In my opinion, it would be easiest if the sources for this library live in the main `jerryscript` project. That way, any changes that affect the client and server sides can be reviewed in a single PR. From a CI/testing point of view, this is also the simplest set up.
That said, how to manage PRs / reviews and make sure we can move fast? I am not sure if the JerryScript core team is comfortable reviewing TypeScript code. Assuming that the people writing the code will mostly be me / my coworkers and not people from the JerryScript core team: we don't want to loose development velocity because the code that gets written doesn't get reviewed and approved in a timely manner.
An alternative approach could be to develop initially in a different repo (under our control) and contribute it back "wholesale" at once (and potentially deprecate that different repo after that point).

###### Test case:
```javascript
/(?:(?=x)){1000}xyz/.exec('xyz');
```
Usually, I do not report stack-overflows since they are due to recursive js calls mostly.
However, in this case the failure disappears if I remove either the positive lookahed or the non-capturing brackets.
So I leave to the experts to decide whether this is a feature or a bug.

[
"jerryscript-project",
"jerryscript"
] | I have the latest JerryScript from the master branch. And tried to do something that worked some time ago. Namely - execute a snapshot and from the snapshot call a function.
Here are the steps that I have used:
1. I have a `tests.js` with the following content
```js
function sysloop() {
// empty function...
};
print("main js OK");
```
2. I have compiled the `jerry-snapshot` binary using the minimal profile.
3. Then I created a snapshot using the command below:
```
./build/bin/jerry-snapshot generate -o tests.js.snap tests.js
```
Which produced a file with the following data in it:
```

0000006c
```
5. After that I tried to load the snapshot and run a function from it using the code below:
```C
// check the arguments 1 - snapshotname, 2 - function to call
if(argc != 3) {
printf("Usage:\n\t%s <snapshot-file> <function-name>", argv[0]);
return 1;
}
// load the snapshot
const uint32_t *snapshot_p = read_file (fileName, &snapshotSize);
if (snapshot_p == NULL)
{
printf("Snapshot file load error");
return 2;
}
// Initialize the JS VM
jerry_init(JERRY_INIT_EMPTY);
// execute the snapshot
ret_value = jerry_exec_snapshot (snapshot_p, snapshotSize, true);
if (jerry_value_has_error_flag (ret_value))
{
jerry_release_value(ret_value);
printf("Unable to execute the snapshot");
return 3;
}
jerry_release_value(ret_value);
// run the function
jerry_value_t global_obj_val = jerry_get_global_object();
jerry_value_t prop_name_val = jerry_create_string((const jerry_char_t *) functionName);
jerry_value_t jsFunction = jerry_get_property(global_obj_val, prop_name_val);
jerry_release_value(prop_name_val);
if (jerry_value_has_error_flag(jsFunction)) {
debugf("Error: '%s' not defined!", functionName);
jerry_release_value(jsFunction);
jerry_release_value(global_obj_val);
return false;
}
if (!jerry_value_is_function(jsFunction)) {
debugf("Error: '%s' is not a function!", functionName);
jerry_release_value(jsFunction);
jerry_release_value(global_obj_val);
return 4;
}
int ret_code = 0;
jerry_value_t res = jerry_call_function(jsFunction, global_obj_val, NULL, 0);
if (jerry_value_has_error_flag(res)) {
ret_code = 5;
}
```
And the test C application above is compiled with the same flags as the minimal profile
```sh
gcc -std=c99 -Wall -Os -g -O2 -Wpointer-arith -Wno-implicit-function-declaration -Wl,-EL -fno-inline-functions \
-DCONFIG_DISABLE_BUILTINS -DCONFIG_DISABLE_ES2015 -DCONFIG_DISABLE_UNICODE_CASE_CONVERSION -DCONFIG_DISABLE_DATE_BUILTIN -DCONFIG_DISABLE_STRING_BUILTIN \
-DCONFIG_DISABLE_REGEXP_BUILTIN -DCONFIG_DISABLE_TYPEDARRAY_BUILTIN -DCONFIG_ECMA_NUMBER_TYPE=CONFIG_ECMA_NUMBER_FLOAT32 -DCONFIG_MEM_HEAP_AREA_SIZE=512 \
-DCONFIG_ECMA_LCACHE_DISABLE -DJERRY_DISABLE_JS_PARSER -DJERRY_ENABLE_SNAPSHOT_EXEC -DJERRY_NDEBUG -D_BSD_SOURCE \
-D__attr_always_inline___= -DJERRY_CONST_DATA="" -Ijerry-core/ -Ijerry-core/jmem -Ijerry-core/lit -Ijerry-core/ecma -Ijerry-core/ecma/base \
-Ijerry-core/ecma/operations -Ijerry-core/ecma/builtin-objects -Ijerry-core/ecma/builtin-objects/typedarray -Ijerry-core/parser \

-Ijerry-core/jcontext -Ijerry-core/debugger \
-c js-snapshot.c
```
BUT the code runs until it reaches the following condition
```
if (!jerry_value_is_function(jsFunction)) {
debugf("Error: '%s' is not a function!", functionName);
```
and reports that "sysloop" is not a function?
Therefore I would be very thankful if someone can explain me what am I doing wrong? Again, this is a code that used to work with older versions (at the times when the snapshot save format was having v 6 (now it is v8) )

Both strings should match:
```
bad = "'detailForm','detailForm:j_id166', []);\" ><img alt=\"Export to XLS format\" />\n</a>"
good = "'detailForm','detailForm:j_id166');\" ><img alt=\"Export to XLS format\" />\n</a>"
r = /'(detailForm:j_id\d+)'[^>]+>[^>]+Export to XLS format/;
[!!good.match(r), !!bad.match(r)]
```
The result is `true,false`. It looks like the brackets in the `bad` string are the culpint.
---
The bug is actually much simpler: Both `'['.match(/[^>]/)` and `new RegExp("[^a]").exec("[")` return null. The opening brace seems to be missing in negated character classes (tested on desktop Linux i686 athlon).

] | How do you guys feel about adding the "safe" variants of libc functions, for example `memcpy_s`, `strcpy_s` etc? In our project, we're trying to eliminate use of the "unsafe" variants.
I would expect the code size to go up a little bit because of the additional argument(s).
So perhaps it should be a config `#define`?
OTOH, I think replacing the "unsafe" ones with "safe" ones would I think would avoid accidents and also avoid having `#define`s all over the place.
I imagine to add implementations to `jerry-libc`, I suspect some toolchains may not support these C11 additions yet. Having them in `jerry-libc` would be an easy compatibility path for those cases.

] | Specifically this check `(ecma_string_get_size (str_p) > buffer_size)` is exiting as expected if the jerry value is larger than the buffer.
However it would be nice if there was another function that would be more tolerant of too big jerry string, by simply dropping the extra characters.
I'm not too sure on the best option of dealing with this. Should this be a seperate function like `jerry_string_to_char_buffer_unsafe()`?
Note: If you are approaching this, then also check if ecma_string_copy_to_cesu8_buffer() actually checks buffer_size(), as memcpy uses the jerry string size rather than declared buffer size (or the smallest of either).

] | Hey JrS people!
I'm trying to implement a native binding much alike Node's [`require.resolve()`](https://nodejs.org/api/modules.html#modules_require_resolve_request_options)
The tricky thing about the `require.resolve` function is that when using a relative path, i.e. `require.resolve('./thing.js')` the look up happens relative to the source file in which the `require.resolve()` call was written.
I noticed that for the JerryScript debugger support, `jerry_parse_named_resource` was added, which seemed promising at a glance. Unfortunately, the "resource name" is merely passed off to the debugger client and not kept around.
Any suggestions on how to solve this?
I guess I want an API like `const jerry_char_t *jerry_get_current_resource_name(void);` that would return the currently executing resource name (or `NULL` if no named resource is executing / it's not available).
For reference, V8 has a [`GetScriptName()`](https://v8docs.nodesource.com/node-9.3/dd/d1e/classv8_1_1_stack_frame.html#a63d53e7637627027f0fe77e0e9dbeab7) method on the `StackFrame` class which is similar to what I'm looking for. | Keep resource name for function objects? | https://api.github.com/repos/jerryscript-project/jerryscript/issues/2170/comments | 3 | 2018-01-23T10:05:20Z | 2019-10-21T13:19:49Z | https://github.com/jerryscript-project/jerryscript/issues/2170 | 290,776,978 | 2,170 |

] | After the recent conversation on DigitalIn and friends, I think we need to change how the Mbed OS and JerryScript integrate. Having part of the build toolchain in jerryscript core repository does not make sense, and things like generating `main.cpp` and the `Makefile` from here are also annoying for users, as they'd need to dive into the jerryscript repository to change these. Additionally, the Mbed.js build system is now different from the normal Mbed OS build system, which adds overhead.
So in the next few weeks I plan to open a PR to remove the mbedos5 target from JerryScript.
Current development for the new system is at https://github.com/ARMmbed/mbed-js-v2 - this no longer requires mbedos5 target in JerryScript to be present. | Remove mbedos5 target | https://api.github.com/repos/jerryscript-project/jerryscript/issues/2149/comments | 4 | 2017-12-13T08:41:26Z | 2019-01-11T16:20:42Z | https://github.com/jerryscript-project/jerryscript/issues/2149 | 281,666,091 | 2,149 |

```
jerry> { a: 1, b: "abc" }

The above expression results a parsing error. But, the below works well.
```
jerry> var x = { a: 1, b: "abc" };
undefined
```
One more strange thing is the following:
```
jerry> { a: 1 }
1
```
This should results "[object Object]", isn't it?

[
"jerryscript-project",
"jerryscript"
] | I was trying to put a code compiled with Emscripten and run them on both node.js and iot.js, however iot.js fails to parse a particular regular expression. After tracing the issue I think JerryScript is not-compliant with other ECMA Script implementations.
The line given by Emscripten is (matching a JavaScript function):
`var sourceRegex = /^function\s*[a-zA-Z$_0-9]*\s*\(([^)]*)\)\s*{\s*([^*]*?)[\s;]*(?:return\s*(.*?)[;\s]*)?}$/;`
The minified code which produces a parsing error in jerryscript is:
`var sourceRegex = /{}/;`
On other JavaScript engines (like v8, node.js and the script console on my Firefox), the above minified code passed the parsing, while in JerryScript (and thus iot.js), it results in a parsing error.
Section 15.10 of ECMA262 seems to allow the above regular expression as the "{" (or "}" character) can be interpreted as an Atom instead of a start of QuantifierPrefix:

"jerryscript-project",

] | @jiangzidong the following code snippet is based on https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise/catch
```js
var p1 = new Promise(function(resolve, reject) {
reject('Failed');
});
p1.then(function(value) {
console.log(value); // "Success!"
}).catch(function(e) {
console.log(e); // "oh, no!"
throw e; // forward the error
}).then(function(){
console.log('after a catch the chain is restored');
}, function () {
console.log('Not fired due to the catch');
throw("This won't be caught");
});
```
My question is that how can I throw an error from a Promise? The code above works with V8 (tested on node.js and chrome console) but not in JerryScript. What is the correct behavior? I'd like to validate the `resolve` and `reject` calls in `then`, but I cannot throw an error from `then`. | How to throw an exception in Promise | https://api.github.com/repos/jerryscript-project/jerryscript/issues/2109/comments | 1 | 2017-11-16T09:46:18Z | 2018-02-16T09:29:41Z | https://github.com/jerryscript-project/jerryscript/issues/2109 | 274,452,815 | 2,109 |

"jerryscript-project",
"jerryscript"
] | During the scripting of target build test automation for Travis CI (#2102), several issues have been identified:
- [ ] ESP8266:
- The apt dependencies list was overly extensive (at least compared to what Travis CI had already installed on the worker image), sometimes even erroneous (e.g., didn't have to install any `libc6-dev*` packages and actually couldn't install `libtool-bin` because such a package was not available).
- The creation of the `/opt/Espressif` directory is described together with the `dependencies` step although it belongs to the crosstool-NG building step. Moreover, it should be noted that neither the building of ct-ng nor the execution of ct-ng to build a cross toolchain requires elevated privileges (it can be done somewhere in the user's home directory, not under `/opt` only).
- Building crosstool-NG didn't work for me exactly as described, `make` detected recursion and bailed out.
- When building the firmware with JerryScript, why must `BIN_PATH` be specified? Couldn't it have at least a default to be the same as `BUILD_DIR`?
- [ ] Mbed OS 5:
- The target needs heavy maintenance. As is, building an example app or a library from sources present under `targets/mbedos5` with the Makefile is not possible. `make all` errors because there is no `main` in the code base, `make library` errors because launcher sources require `jerry-targetjs.h` that are explicitly not generated for libraries. Then the readme suggests to do a gulp-based build, but that build system uses a pinned JerryScript version (https://github.com/ARMmbed/mbed-js-gulp/blob/master/main.js, `const JERRYSCRIPT_REVISION = '5cdb98c75ec231806677a8af0b16d508b1033eb2';`) not master. So that seems never building with latest jerry. The target should always be able to test latest developments.
- [ ] NuttX:
- The readme doesn't mention which version of NuttX was last seen working. (7.22 worked for me, see makefile.)
- The readme doesn't describe how configuration can be automated (without menuconfig that requires user interaction). Moreover, the readme suggests fetching the kconfig sources from a "3rd party" while the nuttx/tools repo contains its own kconfig sources.
- [ ] Particle: I couldn't get it to build at all.
- [ ] RIOT:
- The readme doesn't pin the last known working version of RIOT. (2017.10 worked for me.)
- [ ] Tizen RT:
- The readme doesn't pin the last known working version of Tizen RT. (1.1_Public_Release worked for me but only if I adapted the romfs patch.)
- PPA-based GCC6 version worked, too (readme mentions GCC4.9, but that just seems to be a lower bound, not a must).
- [ ] Zephyr:
- The readme doesn't pin the last known working version of Zephyr, which is quite an issue. Zephyr has changed build system on master to something cmake-based, which is completely incompatible with the code in `targets/zephyr` right now. For me, Zephyr 1.9.1 and Zephyr SDK 0.9.1 worked. (But even in this release, Zephyr doesn't seem to have the readme-suggested `qemu` make target anymore.)
- Non-interactive installation required quite some recursive digging into self-extracting archives within self-extracting archives, because documentation suggests interactive installation of the SDK by "ansering all questions" (out of question on Travis).
- Directory structure suggested by readme has `zephyr-project`, although when I clone it out from github, it will be named `zephyr` by default.
- Calling make with `./targets/zephyr/Makefile.zephyr` fails to build the JerryScript library with quite weird errors... unless you set CC to point deep within the Zephyr SDK: `zephyr-sdk-0.9.1/sysroots/x86_64-pokysdk-linux/usr/bin/i586-zephyr-elfiamcu/i586-zephyr-elfiamcu-gcc`. Which is not documented anywhere and was a hell to debug. Note: zephyr sets its the build environment for its own build system up by sourcing `zephyr-env.sh`, but JerryScript's build system will know nothing about that. And `Makefile.zepyhr` will use `$CC` which is usually still set to the native compiler.
It would be great if target maintainers could check these out.

"jerryscript-project",

] | Before PR #2042, `jerry_value_clear_error_flag` and `jerry_value_set_error_flag` would take a `jerry_value_t *` and set a flag onto it. After each of these calls return, the `jerry_value_t` that the pointer points to would still be a reference to the same JS thing as before.
After PR #2042, after the `jerry_value_set_error_flag` returns, the `jerry_value_t` is updated to reference a *different* value (the error "box"). Same with `jerry_value_clear_error_flag`, it expects to take an `jerry_value_t *` pointing to such an error "box" and after the call returns, the `jerry_value_t` will contain the unboxed value.
Even though this change is source and binary compatible, semantically it's not compatible (and thus breaking the API, IMHO).
One of the more serious implications is that the client code needs to be aware of the "swapping" of the `jerry_value_t`:
Contrived example:
```
jerry_value_t sth = ...;
sth = jerry_acquire_value(sth); // this worked fine before #2042
jerry_value_set_error_flag(&sth);
// Whoops! After PR #2042 the boxed value is not acquired...

```
Unless we really need to free up the error flag bit in the `jerry_value_t` *now*, I'd revert #2042, I'm afraid it will break people's projects in unexpected ways. At the very least, the docs should be updated – this change is more than a transparent implementation detail.
If the freed up bit is actually really needed now, perhaps create a new API with a name that better matches what happens under the hood, mark the old one deprecated. The old one can call the new implementation, but at least this way there's a mechanism to get people's attention after pulling from upstream.

] | Hi Guys,
I want to build Jerryscript for NuttX on a NUCLEO-F401RE board.
I followed the instructions exactly in the https://github.com/jerryscript-project/jerryscript/tree/master/targets/nuttx-stm32f4 except for step 3, I used ./configure.sh nucleo-f4x1re/f401-nsh.
And when I try to build JerryScript for NuttX (Step 4) using :
cd nuttx/
make
I got this error :
make[2]: Leaving directory '/home/ubuntu/jerry-nuttx/nuttx/configs/nucleo-f4x1re/src'
LD: nuttx
arm-none-eabi-ld: /home/ubuntu/jerry-nuttx/nuttx/nuttx section `.bss' will not fit in region `sram'

We have `jerry_value_is_constructor ()` which allows one to determine if a value can be used as a constructor, and we have `jerry_construct_object ()` which allows one to instantiate a new object using an existing constructor, but we don't have `jerry_create_constructor (jerry_external_handler_t native_function_p)`, which would allow one to create a new constructor and then add properties to its prototype and static ones to the constructor itself.

For the time being, I am fixing my issue with STM32F429ZI by writing the following line in try statement:
```
try:
pins[pin.name] = evaluator.eval(expr.strip())
except:
print("[Error]. Problem while evaluation expression.")
```
The script runs fine for K64F and STM32F401RE boards which don't have expressions in their PinNames.h file. | Problem with generate_pins.py script in mbedos5 | https://api.github.com/repos/jerryscript-project/jerryscript/issues/2038/comments | 2 | 2017-10-04T13:44:53Z | 2018-05-10T06:34:29Z | https://github.com/jerryscript-project/jerryscript/issues/2038 | 262,792,876 | 2,038 |

The advantage of that approach is we can free up the flag bit in the jerry value, so new JS types such as symbols could be implemented. The drawback is a breaking API change.

Assigned as CVE-2017-14749, Credit by ADLab of Venustech
PoC.js is as follows(hex displayed):
```
00000000: 275c 0a27 2b27 3035 3627 3b0a '\.'+'056';.
```
Among the first string, there is a '\n'(0x0a). This byte could be replaced by '\r'(0x0d) or other bytes as with a '\\' at front. And this kind of bytes makes the generated byte code contains an NULL word(0x00), which lead to a crash as the following stack trace shows:

#### Root cause
When processing the strings, the generated byte code are as follows:
```
b vm.c:669
668 uint8_t *byte_code_p = frame_ctx_p->byte_code_p;
669 jmem_cpointer_t *literal_start_p = frame_ctx_p->literal_start_p;
crash:

08289b64 60 fe 07 00 00 00 00 00 00 00 00 00 00 00 00 00

08289b84 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
normal:
08289b6c [32 00 29 00] 86 00 01 08 46 00 00 00 ff ff ff ff
08289b7c 48 fe 07 00 00 00 00 00 00 00 00 00 00 00 00 00

08289b9c 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
```
The NULL word in 0x00290000 is one of the bytecode.literal compressed pointer. When bytecode is executed, the reference of the literal add 0x10 while jerry_global_heap.next_offset was overwritten because of the compressed pointer. Twice as it was referenced so the field was added up to 0x20. This makes the index of the free chunk lists corrupts.
#### Potential Risks
With the heap memory corruption the free chunk lists could be faked. Potentially there exists an local write primitive in memory. If jerry is embedded in some host and could execute js, this vulnerability could result in remote code execution.
#### Fix Suggestion
Check code in bytecode generation: the failed literal's compressed pointer should not be NULL word.
| Security: NULL word of bytecode.literal lead to heap memory corruption results in OOB write. | https://api.github.com/repos/jerryscript-project/jerryscript/issues/2008/comments | 2 | 2017-09-07T07:48:07Z | 2017-10-30T20:56:19Z | https://github.com/jerryscript-project/jerryscript/issues/2008 | 255,845,370 | 2,008 |

I would like to nominate SangGyu Lee (glistening) to be a JerryScript committer. I trust him to follow our process. His patch list follows:
- Fix new ArrayBuffer(length) for variaous input (#1959)
- Implement typedarary.set(array, offset) (#1958)
- Change tizenrt-artik05x port reference board to artik053 (#1904)
- Fix build warning in jerry-ext/arg on tizenrt-artik05x (#1906)
- Don't allow supplementary character as identifier start or part (#1899)
- Handle negative zero in number multiplication (#1856)
- Add `setjmp` and `longjmp` functions for tizenrt-artik05x (#1825)
- Use external handlers in tizenrt-artik05x target (#1822)
- Include jerry-ext/handler only in nuttx-stm32f4 target (#1816)
- target: tizenrt-artik05x: Add missing jerry_port.c (#1786)
- target: tizenrt-artik05x: Initial porting (#1775)

[
"jerryscript-project",
"jerryscript"
] | I noticed that certain features affect the snapshot output format (logically so):
- whether uncompressed / 32-bit pointers is enabled
- machine endianness
- js-parser-limits.h values – `PARSER_MAXIMUM_CODE_SIZE` affects the byte code generation. I'm not sure if any of the other parser limit values are relevant when loading a snapshot.
- whether `RegExp` literal templates are used in the snapshot (a JerryScript VM that is compiled w/o `RegExp` support will hit `JERRY_UNREACHABLE ()` when loading a snapshot with a regular expression template literal)
- probably more...?
Right now, there's no nice way to check whether a snapshot is really compatible before running it.
Would it make sense to add this information to the `jerry_snapshot_header_t`?
@LaszloLango also hinted on IRC at that the magic strings list may also cause snapshots to become different, but I did not observe this when comparing outputs. | Add relevant features/snapshot properties bitset to snapshot header | https://api.github.com/repos/jerryscript-project/jerryscript/issues/1981/comments | 7 | 2017-08-25T20:22:36Z | 2017-10-12T17:49:20Z | https://github.com/jerryscript-project/jerryscript/issues/1981 | 253,008,488 | 1,981 |
[
"jerryscript-project",
"jerryscript"
] | I'm interested in having a JavaScript library / module that can take a JS source string and produce a JerryScript snapshot. At a previous company, we had built something like this, simply by using Emscripten to transpile the C code that produces snapshots into JS. The advantage is that such a library is very easily "portable" to other platforms (i.e. cloud, mobile, browser, etc.)
Any objections if I add an option to JerryScript's build system to produce such a library? | Add jerryscript-snapshot-compiler.js ? | https://api.github.com/repos/jerryscript-project/jerryscript/issues/1977/comments | 7 | 2017-08-23T14:49:03Z | 2019-10-25T18:54:42Z | https://github.com/jerryscript-project/jerryscript/issues/1977 | 252,310,618 | 1,977 |

The value for the arguments length is passed in via the bytecode - it's an opcode (the next one!) and it's stored in js-parser.c, on line 1711:

So here is the interesting part: I wrote a minor fix on this, but found it can't pass the vera++ check (which forced us to place FALLTHRU before right bracket).

[
"jerryscript-project",

] | I ran into a problem today where an object wasn't getting freed. It turned out this was because its native pointer struct held acquired references to "listener" functions which in turn were bound to a scope object that held the original object as a property. I had to dig deeply into the GC today to learn about these things; before I had assumed that once refcounts went to 0, it would be freed. But there are essentially these "weak references" of 10 different types I see in gc_mark().
Anyway, I had been expecting when the reference count went to zero I would get my type_info's free_cb() called and that was where I was releasing these listener functions. It seems to me now that for this kind of case, there should perhaps be release_cb() in the type_info as well. I'm thinking when my refcount drops to zero I could probably release my own references like this. But maybe I'm wrong, it's a bit confusing.
I could use advice if there's another way to solve this. Previously we had implemented a "hidden property" to store an array of listeners; so these were held by "property reference" and disappeared. But this hidden property implementation was also something of a hack of JerryScript and a clever JS user could maybe have accessed it. So another good way to solve this might be for JrS to provide a way to define properties on objects that are hidden to JS and visible only from C APIs. I wonder if others have desired these same things?

( I pushed #1959 before I recognise it. I would like to get opinions. )
For example,
`ES2015`
_new ArrayBuffer(1.1)_ should throw RangeError.
`ES2017`
_new ArrayBuffer(1.1)_ creates ArrayBuffer with byteLength=1.
I would like to follow ES2017's definition.
Major engines (v8/spidermonkey/jsc) already work like ES2017 spec. ( Or ES specification may be updated to follow major engines. [ES2016](https://www.ecma-international.org/ecma-262/7.0/index.html#sec-arraybuffer-length) specification was same to ES2015. ).

`module_name` is stringified, which will cause the argument to not be evaluated by the preprocessor but used verbatim.
After having used the macro in practice, I found that it's not desirable to stringify it, because:
- it prevents one from creating macros that call the `JERRYX_NATIVE_MODULE` macro and pass in a variable module name
- it makes it impossible to single-source the module name, i.e. I cannot write something like:
```
#define MY_MODULE_NAME my_module
#define MY_MODULE_NAME_STR STRINGIFY(MY_MODULE_NAME)
void
foo (void)
{
const jerry_value_t m = call_require(MY_MODULE_NAME_STR);
// ...
}
// module will actually be named "MY_MODULE_NAME"...
JERRYX_NATIVE_MODULE(MY_MODULE_NAME, ...)
```
Therefore I propose to remove the stringification (`#`) from the macro.
I realize it's a breaking change, but the API is pretty new and the migration path is super simple.
Thoughts @gabrielschulhof ?

jerry_json_replacer_t replacer,
jerry_value_t space);

Note the output of `jerry_json_stringify` is not a UTF-8 C string (`jerry_char_t[]`). Although in most cases you probably want a C string...:
1. how to allocate the buffer for the C string?
2. what's an elegant way to deal with any errors – perhaps a `jerry_value_t *error_out`?
