thread scope being reported as unscoped

Description

1. unscoped, thread scoped variables aren't being resolved inside a thread

Preview unavailable

https://docs.lucee.org/guides/developing-with-lucee-server/scope.html
https://github.com/lucee/Lucee/blob/5.3/core/src/main/java/lucee/runtime/type/scope/UndefinedImpl.java#L215

2. implicit scope access, reports thread scope when accessing a thread scoped variable within a thread?

thread also is not a real scope in Lucee

Zac Spitzer 18 October 2022 at 15:34

this code

 thread name="thread-2773" {         thread.test2773 = "2773";         thread.inThread = isInThread();         thread.keys =  structKeyList(thread);         thread.scope= getPageContext().getThreadScopeNames();         url.zac=1;

generates the following bytecode

paramPageContext.set(paramPageContext.touch(paramPageContext.us(), this.keys[2]), this.keys[3], "2773"); paramPageContext.set(paramPageContext.touch(paramPageContext.us(), this.keys[2]), this.keys[4], Caster.toRef(IsInThread.call(paramPageContext))); paramPageContext.set(paramPageContext.touch(paramPageContext.us(), this.keys[2]), this.keys[5], StructKeyList.call(paramPageContext, Caster.toStruct(paramPageContext.us().get(this.keys[2])))); paramPageContext.set(paramPageContext.touch(paramPageContext.us(), this.keys[2]), KeyConstants._SCOPE, paramPageContext.getFunction(GetPageContext.call(paramPageContext), this.keys[6], Constants.EMPTY_OBJECT_ARRAY)); paramPageContext.urlScope().set(this.keys[7], ConstantsDouble._1); CFFunction.call(paramPageContext, new Object[] { FunctionValueImpl

thread isn’t being treated a scope here, it’s falling back on the undefined logic, hence why it’s slower, and reporting as unscoped

Unresolved
