Could someone run this on a CF 5 server with full-checking selected in the
memory variables area in the cfadmin and confirm that my CF server isn't
working properly?
This test was written with the intention of confirming that simple values
either do or do not get passed by reference in a <cfset> tag, however, my cf
server seems to not be working, so I can't perform the test, because it's
not producing the expected error from variable accesses which are definitely
improperly locked.
<cfapplication name="pointertest"
applicationtimeout="#createtimespan(0,5,0,0)#">
<cflock scope="application" type="exclusive" timeout="10">
<cfscript>
application.a = "hello world";
application.b = structnew();
application.b.c = "hello world";
application.b.d = structnew();
application.b.d.e = "hello world";
</cfscript>
<cfdump var="#application#">
</cflock>
<cflock scope="application" type="readonly" timeout="10">
<cfset request.a = application.a>
<cfset request.b = application.b>
</cflock>
<cfoutput>
<div>application.a = #request.a#</div>
<div>application.b.c = #request.b.c#</div>
<div>application.b.d.e = #request.b.d.e#</div>
</cfoutput>
After running this, outputting #request.b.d.e# at the bottom should produce
an error since request.b is supposed to be a pointer reference to
application.b and therefore request.b.d.e should be in the application scope
and not properly locked. For that matter, request.b.c should be in the
application scope as well, so both of these should produce an error, but
neither are on my machine, even though full-checking is turned on in the CF
admin.
In any event, if it errors on request.b.c or request.b.d.e but not on
request.a then this confirms that simple values are not passed as pointer
references but as literal strings. That being said, I still think duplicate
should always be applied when using persistent scopes in development /
production.
