CHECK_EQ(Module::kEvaluated, module->GetStatus());

Referring to test-modules.cc in v8 6.7, is the following part of the module
standard?
import {a, b} from 'export var a = 1; export let b = 2';
If so, how do I differentiate a module definition from a module name/path?

15134520.

I modified v8 shell.cc to experiment with the new Module API and am trying

If the resolve callback calls v8::Isolate::throwException, I get:

Embedding v8 5.3. The embedding application allows JavaScript programs to
import other library modules similar to Node.js require. I noticed a
change of behavior after upgrading from v8 4.6.88 to 5.3. That is, if the
imported library module is in strict mode, the stack trace of a function

Running a memory-consuming script. Sometimes I get a fatal error callback

With the embedded scenario, it would be desirable to have some API to

We embed v8 version 4.6.88.
Looking at flag-definitions.h, I know some ES6 features are tracked by a
flag and can be turned on/off. How do I get a list of features that are
always turned on and not tracked by a flag, such as Iterator, Generator and
Symbols, for example? Is there a documentati
Once the .sln and .vcxproj files are generated through python, how is one
supposed to re-generate them with different gyp flags? When I run:
python build/gyp_v8 -Dtarget_arch=x64 -Dv8_use_external_startup_data=0
for example, I get "updating project files...", but then only to find out
nothing
I added it to toolchain.gypi and that seems to do it.

v8 on Windows has the default _ITERATOR_DEBUG_LEVEL value, which conflicts
with another Windows library I'm embedding. So I'd like to set the
_ITERATOR_DEBUG_LEVEL to 0 while building v8. I haven't quite figured out
how to do it either by editing v8.gyp or the generated VS solution files.

Ben,
Manually adding WinMM.lib to my project did it for me. Thanks a lot.

It's intermittent for me somehow in cygwin. Even after I set
DEPOT_TOOLS_WIN_TOOLCHAIN=0. But what worked for me is to run "fetch v8"
in Windows PowerShell. Still a mystery...

I was able to build v8 4.6.88 successfully with Visual Studio 2013 with the
following flags:
-Dtarget_arch=x64 -Dv8_use_external_startup_data=0
I got the following libraries:
$ ls -l build/Release/lib
total 353468
-rwxr-xr-x 1 jchen Domain Users 3140002 Dec 21 17:20 gmock.lib
-rwxr-xr-x 1 jc
This seems only a problem with debug build. Optimized build works fine.

Thanks a lot! It sure helps.
I found CpuProfileNode.GetNodeId(). Maybe that's the pre-computed id which
is the same as what you show here?

I'm trying to serialize the CpuProfile object to a JSON serialization
compatible to Chrome's .cpuprofile file. The part I'm not clear about is
the samples array in the .cpuprofile file:
"head":

"startTime": 1611259.054962,
"endTime": 1611262.312964,

Is my understanding correct that turning on v8 debugging is global for all
isolates? Is there a way to turn on v8 debug for just one isolate? What
is the performance implication to turn on v8 debug?
Thanks in advance.

Ben,
In v8 4.6.88, I can no longer find src/debug-debugger.js, nor
src/{liveedit,mirror}-debugger.js. Does it mean that the function-based
API is also deprecated and removed?

Hi Ben,
Thanks for the info!
Is the function-based debug API still supported? Is there any reference or
code examples for using that?

Just went to this link:
https://chromium.googlesource.com/v8/v8/+/master/docs/debugger_protocol.md
and found that "*The message based API is no longer maintained.*"
Does that mean that users (or embedders) should no longer use the message
based API since it is no longer supported?
On Thursday,

4.6.88. Just tried it in v8 shell. myIterable[Symbol.iterator].next is
undefined.

If I have an iterator (natively defined) which supports for ... of loop,
what is the equivalent of calling next to advance it?
I hope the following js example demonstrates what I
