Hi i try create simple module for python:
class Browser
{
public:
Browser();
void getContext();
const char* execute(const char* data);
int test;
private:
v8::Isolate* _isolate;
v8::Handle<v8::Context> _context;
};
Browser::Browser()
{
v8::V8::InitializeICU();
v8::V8::InitializeExternalStartupData("/opt/v8build/");
v8::Platform* platform = v8::platform::CreateDefaultPlatform();
v8::V8::InitializePlatform(platform);
v8::V8::Initialize();
ArrayBufferAllocator allocator;
v8::Isolate::CreateParams create_params;
create_params.array_buffer_allocator = &allocator;
_isolate = v8::Isolate::New(create_params);
}
const char* Browser::execute(const char* data)
{
v8::Isolate::Scope isolate_scope(_isolate);
v8::HandleScope handle_scope(_isolate);
if (test != 1) {
printf("%s\n", "New context");
test = 1;
_context = v8::Context::New(_isolate);
}
const char* result;
{
// v8::Handle<v8::Context> context = v8::Context::New(_isolate);
v8::Context::Scope context_scope(_context);
v8::Local<v8::String> source =
v8::String::NewFromUtf8(_isolate, data,
v8::NewStringType::kNormal).ToLocalChecked();
v8::Local<v8::Script> script = v8::Script::Compile(_context, source).
ToLocalChecked();
v8::Local<v8::Value> result = script->Run(_context).ToLocalChecked();
v8::String::Utf8Value utf8(result);
// Konwersja danych do char*
int len = utf8.length() + 1;
char *str = (char *) calloc(sizeof(char), len);
strncpy(str, *utf8, len);
return str;
}
return result;
}
Tutaj wprowadź kod...
First run execute is ok, but second run execute return error
Program received signal SIGSEGV, Segmentation fault.
0x00007ffff5998a7a in v8::Context::Enter()
Anyone can help me? Thanks :)
