[v8-users] Re: gyp_v8 error when building

2016-07-27 Thread spaesani . console

Sorry bout the verbosity MIchael. The last post was mostly a joke.

To be clear the issue is the* current_hashes  [] *
It's empty.
It's set in get_toolchain_if_necesssary.py around line 480

  current_hashes = CalculateToolchainHashes(target_dir, True)

I'm not familiar with google builds and have no idea what it's looking for. 

I'm building on a GYP_MSVS_VERSION=*2015*

I think I'm zeroing in on it

get_toolchain_if_necesssary.py
  toolchain_dir = '.'
  target_dir = os.path.normpath(os.path.join(toolchain_dir, 'vs_files'))

  target_dir == vs_files  // <--!

it's empty
?

I can only repeat myself. It wouldn't enter this code if the environment 
variable I mentioned above was set correctly. If you do enter this code, 
it's not set. And it is expected to fail (it could fail in nicer ways for 
sure).

The script get_toolchain_if_necessary.py is called in your above stack 
trace in vs_toolchain.py line 336, in Update
 
This is roughly:
https://cs.chromium.org/chromium/src/v8/gypfiles/vs_toolchain.py?l=331

Update is called by SetEnvironmentAndGetRuntimeDllDirs line 44 which it 
should not have entered in the first place as described above.

I'm building on a GYP_MSVS_VERSION=*2015*

 Not officially supported yet, but should compile at least. The variable 
will probably be ignored as you're required to have msvs 2015 installed.

Cheers

Thanks for your help Michael. I thought the "if you're not a googler" and 
the env var was a joke to cut the build short. But I se it also 
at 
https://chromium.googlesource.com/chromium/src/+show/master/docs/windows_build_instructions.md

Thanks again for your help.

I might give v8 a shot on a linux box someday but maybe it's all for the 
best.

Cheers

Re: [v8-users] Exposing nested maps from C++ into JS world

Can you provide a complete example? I suspect that WrapHTTPBodyMap doesn't
do what you expect it does

Re: [v8-users] Exposing nested maps from C++ into JS world

Hi Jochen,

Full code of relevant file available - http://pastebin.com/fZJENvSi 


Snippet of relevant portions for WrapHTTPBodyMap:

Local HTTPBody::MakeHTTPBodyMapTemplate(
Isolate* isolate) {
  EscapableHandleScope handle_scope(isolate);

  Local result = ObjectTemplate::New(isolate);
  result->SetInternalFieldCount(1);
  result->SetHandler(NamedPropertyHandlerConfiguration(NULL,
   HTTPBodySet));

  return handle_scope.Escape(result);
}

Local HTTPBody::WrapHTTPBodyMap() {
  EscapableHandleScope handle_scope(GetIsolate());

  if (http_body_map_template_.IsEmpty()) {
Local raw_template = MakeHTTPBodyMapTemplate(GetIsolate());
http_body_map_template_.Reset(GetIsolate(), raw_template);
  }
  Local templ =
  Local::New(GetIsolate(), http_body_map_template_);

  Local result =
  templ->NewInstance(GetIsolate()->GetCurrentContext()).ToLocalChecked();

  Local map_ptr = External::New(GetIsolate(), &http_body);

  result->SetInternalField(0, map_ptr);

  return handle_scope.Escape(result);
}
