SInce Microsoft has ended support for CC a while ago i think we should update README.md to remove the notice about support from Microsoft or update it.
I want to fix this and If you may trust me in doing this, may i ask you a question - Do you still accept security issues for 1.11 release?

This is a discussion to determine what should go into the next release w.r.t WebAssembly. We have updated the SIMD opcodes somewhat recently, and I am inclined to remove anything else that is not yet in from the upcoming release.
Things among open issues that are worth noting, in my opinion:
- #6524 - request to throw an exception when Wasm runs out of stack space, rather than just crashing. It is planned for the next release, but since we haven't gotten to it my feeling is that we should postpone it.
- #6434 - getting us up to speed with Wasm SIMD. It is more or less a project, as it add new webassembly instructions, and requires some backend support. It is an important milestone in Wasm support, and CC has more than half of that functionality working already.
- #6396 - obvious optimization of Wasm shuffles. It is needed in order to stop shuffles from being embarrassingly slow.
- Other Wasm features ([project](https://github.com/chakra-core/ChakraCore/projects/1)) - longer term work.

Hello!
I'm using chakraRT (in windows), but I also sometimes use chakracore in osx and linux (as well as jscore, both ios/osx natively and the open source one)
I've recently re-enabled `JsStartDebugging()` and hurrah! visual studio 2017 now shows code! (It used to just show when there was an exception, but no source, debugging, no idea what made it start working)
I've also implemented modules, via multiple contexts (in jscore and chakra). It all seems to be working fine, except I can only enable debugging for my first script....
Subsequent calls to `JsStartDebugging()` when creating my new context (which is during script execution of the parent-context) returns `JsErrorRuntimeInUse`.
I've read on another issue, that's because a script is currently being executed... but I'm on a different current context (same vm), so should I really see the error?
Does it need to be called outside of any script execution in the VM?
the headers say `Starts debugging in the current context.` so I assume that's correct that debugging needs enabling per-context, not per-vm?
My flow;
`Create VM`
`Create ContextA`
- `Set ContextA active`
- `Enable debugging (success)`
- `Set no active context`
`Bootup`
- `Set ContextA active`
- `Execute bootup.s script (imports ImportB.js)`
- - `Create ContextB`
- - `Set ContextB active`
- - `Enable debugging (fails JsErrorRuntimeInUse)`
- - `Execute ImportB.js`
- - `Set ContextA active (popped from stack)`
- - `Continue ContextA/script execution`
- `Bootup.js/ContextA finishes - set no active context`
`Run pending async jobs` (run on their respective contexts)
Visual studio only shows the bootup script in the debugger, so, I guess it is context specific...
I only ask as moving the debugger enabling is slightly awkward (but I can do it), but it does mean it's after the module initialisation, so I'd never be able to debug the actual import (but I can live with that)
But I'm also not sure if I'm setting up debugging correctly for multiple contexts (Info about debugging is extremely rare!)
Side note; if I'm doing multiple contexts incorrectly, do let me know! (should I switch active contexts this way?)
JavascriptCore is threadsafe for JS calls, but not script execution, chakra seems to be similar, and working so far :)

(tested with 1.11.24.0 on Mac OS)
This is one of those "I went looking for dumb edge cases" bugs. It didn't come up in real code - it requires code to be _very_ poorly written - and should be prioritized accordingly. Anyway:
```js
let evil = new RegExp;
evil.exec = () => ({ 0: '1234567', length: 1, index: 0 });
'abc'.replace(evil, `$'`);
```
and
```js
let evil = new RegExp;
evil.exec = () => ({ 0: 'x', length: 1, index: 3 });
print('abc'.replace(evil, `$'`));
```
both produce `abcabc`. The correct results are the empty string and `abc` respectively.
These exercise an extremely dumb case in [GetSubstitution](https://tc39.es/ecma262/multipage/text-processing.html#sec-getsubstitution): in the `$'` case, there is a `tailPos β₯ stringLength` condition. The strict `>` case there is very strange: it means that you have a match M at position P in string S such that the length of M exceeds the number of code units subsequent to P in S. Obviously this does not make sense, and indeed built-in RegExps can't do this (I am reasonably sure).
But this can be achieved by overriding the `exec` method on a RegExp (something [we have not yet gotten rid of](https://github.com/tc39/proposal-rm-builtin-subclassing), unfortunately), either (in the first case) by producing a match string which is longer than the input or (in the second case) by producing a nonempty match string at position past where it could have fit in the input.

Whilst it is now possible to build directly with cmake and skip the build.sh script altogether whilst we continue to provide it we should keep it functional...
New versions of Ubuntu ship without Python2.
Build.sh reference to Python2 for optional LLTng support; AND for setting a relative path and this can cause a build failure on Ubuntu 20 - as per @fatcerberus
We should update build.sh to try checking for python 3 if python 2 is not found.
|
Build.sh may be broken on latest Ubuntu

Hi. You already have a .NET binding here:
https://github.com/chakra-core/ChakraCore/wiki/Embedding-ChakraCore
What about a Java binding?
|
Could you provide a Java binding?

After running small benchmark on Windows 10 with x64_debug config, i've got these results:
```
13996ms (for-of), 90ms (for-non-cached), 63ms (for-cached) (on average after 10 subsequent runs)
For-of is slower than for-non-cached by 15551%
and For-of is slower than for-cached by 22215%!
```
Bench code:
```js
{
const a = Array.from({ length: 1e7 }, _ => 0);
let start = (console.log('Start'), Date.now());
for (const _ of a);
console.log(Date.now() - start + 'ms (for-of)');
start = Date.now();
for (let i = 0; i < a.length; i++) { const _ = a[i]; }
console.log(Date.now() - start + 'ms (for-non-cached)');
start = Date.now();
const length = a.length;
for (let i = 0; i < length; i++) { const _ = a[i]; }
console.log(Date.now() - start + 'ms (for-cached)');
}
```

The following code crashes after about 250 iterations.
```javascript
for(let i=0;i<10000;++i) {
let a=[0.0];
}
```
The crash seems to only happen in a release build and the value in the array needs to be float.

# Cannot finish web-tooling-benchmark test
I'm trying to run [web-tooling-benchmark](https://github.com/v8/web-tooling-benchmark) on ChakraCore (version in master branch) but it seems that it just stuck at coffeescript test and cannot finish the entire test:
```bash

```
Output (stuck at coffeescript test and not able to get the test result):

After viewing of Import assertions proposal, i questioned myself - how will the proposal be supported by JSRT of CC - by adding a separate callbacks with assertions object and keeping or deprecating the old callbacks, or change them to include the assertions object?

https://github.com/chakra-core/ChakraCore/pull/6653 has implemented these methods behind a default off flag: ESArrayFindFromLast
When the proposal reaches stage 3 we should enable the flag, also at that time the two unscopables tests (one with this feature and one without) should be combined, see: https://github.com/chakra-core/ChakraCore/blob/c091b36a2dbd85c568871b8fe49c4f180bab80cc/test/es6/rlexe.xml#L98-L107

Splitting out of the conversation started by @lmcdougald in https://github.com/chakra-core/ChakraCore/issues/6616#issuecomment-789492298:
> Well, EdgeHTML isn't going anywhere from what we know. It'd be interesting to see how much work would be needed to drop ChakraCore in to replace KJS in KHTML (yes, old, but open and provably can be extended into a modern browser).
Also from @curtisman in https://github.com/chakra-core/ChakraCore/issues/6616#issuecomment-792391375:
> ChakraCore should have most of what you need to run with modern browser. I did a quick hacky prototype that shim's v8 API (similar to the shim that enables node-chakra) and able to run Chromium with pretty good perf. Most of the additional code to wire up with any HTML engines deals with projecting the DOM into the JS context and memory management between the two sides.
In my personal view this would be a very valuable experiment - running the engine inside of a browser unlocks a great variety of non-trivial workloads.

Tests in the test suite that check debugger functionality using .dbg.baseline comparison functions auto-pass (or are skipped) when run on macos.
This is frustrating when developing on mac as if a change causes some of these to fail it's not seen until you open a PR + have to update the PR to test the fix.
Unsure what causes this - could be a `ch` error or a `runtests.py` error

I've got a special question:
Is it possible to build ChakraCore and replace chakra.dll on Windows to expose new features to PWA (and Edge Legacy)?
I've read there are only a fiew differences between Chakra and ChakraCore?
If it is: How could it be done?
