WinCE/ARM memory leak after Context::New() in a thread

[neil...@hotmail.com]

Hi,

I have modified the standard platform-win32.cc to build under CE (a
few minor changes) and built an ARM v8 lib.

When I link to this I can create a global ObjectTemplate, create a new
Context from it and compile/run scripts fine provided I do this in the
main application thread.

If I create a thread via CreateThread() and run the same code I leak
~2.1mb for every thread I create. The thread appears to return
correctly and the HandleScope destructor is entered.

The code I'm using in the thread is:

{
Locker locker;
Locker::StartPreemption(100);

HandleScope handle_scope;
Persistent<Context> context = Context::New(NULL, script_global);
Context::Scope context_scope(context);

t = GETTICKSMS;

TryCatch try_catch;
Handle<Script> script = Script::Compile(String::New(thread-
>code.c_str()));

rv = !script.IsEmpty();
if (!rv)
{
str.Format("JavaScript compilation error: %s",
script_extracterror(&try_catch).c_str());
log_add("script_thread(): %s", str.c_str());
}
else
{
Handle<Value> result = script->Run();
rv = !result.IsEmpty();
if (!rv)
{
str.Format("JavaScript runtime error: %s",
script_extracterror(&try_catch).c_str());
log_add("script_thread(): %s", str.c_str());
}
}
context.Dispose();
context.Clear();
}

If I just leave the Locker and HandleScope the leak goes away.

Any ideas?

Thanks,


Neil

Hello,

Currently i'm trying to build V8 engine on Win CE ARM. Can you please share the steps you followed.

This doesn't look WinCE/ARM related. Instead, you appear to never free the persistent handle which then keeps the context alive indefinitely.

I propose to first learn about v8 basics in a less constrained environment, and once you got that working, move on to porting your code to wince.
