There's not enough code here to give a good answer to question 1.

Luke;
OK thank-you for that answer to question 2!
Any thoughts on question 1?

Line 44 creates 2 objects, one goes into the dictRef, the other is
not assigned to a variable, but is used only as the second argument
to MDItemCopyAttributes. The object that you create inside that
call is never released.

Folks;
Alert - potential boneheaded-ness lies ahead - please be gentle.
I'll be the first to admit that I'm much happier in ObjC than C…
I thought I would try static analysis and see what turned up.
On the whole I must say I'm pleased but this one has me
questioning my basic understanding
if (![[NSFileManager defaultManager] fileExistsAtPath:thisPath]) {
…
41 } else {
42 MDItemRef mdi = MDItemCreate( nil, (CFStringRef)thisPath );
43 if ( mdi != nil ) {
44 CFDictionaryRef dictRef = MDItemCopyAttributes( mdi,
MDItemCopyAttributeNames(mdi));
…
CFRelease(dictRef);
} else {
… handle error
}
}
Static Analysis tells me I have a potential leak of object
allocated on line 44 -- that's all.
My questions are:
1) Why is there not a warning for the object allocated on line 42
- mdi ?
2) Why is the CFRelease(dictRef) not sufficient?
Thank you for you patience!
