can't find NSMutableDictionary in source code, is it dependency?

issue present both on 0.4.0 and 0.3.3

AI says one of those:

https://github.com/nashaofu/xcap/blob/master/src/macos/impl_monitor.rs#L29

The leak happens when calling screen.deviceDescription(). That method returns an autoreleased <NSMutableDictionary> which isn’t drained because there’s no autorelease pool in this code block. Wrap those calls in an autorelease pool to fix it.

xcap/src/macos/impl_window.rs

Line 126 in 9b033aa

let cf_array = match CGWindowListCopyWindowInfo(

The leak comes from the CFArray returned by CGWindowListCopyWindowInfo – it isn’t released, so the underlying NSMutableDictionary objects leak.

Tested it here, it was not introduced lately. Version 0.2.0 has the leak.

Both those options you mentioned are using Retain type, which should drop the values.

See on objc2 docs: https://docs.rs/objc2/latest/objc2/rc/struct.Retained.html and https://docs.rs/objc2-core-foundation/latest/objc2_core_foundation/struct.CFRetained.html

Went as deep as I could on this rabbit hole. Version 0.0.1 has the leak.

Process 48460 is not debuggable. Due to security restrictions, leaks can only show or save contents of readonly memory of restricted processes.

Is this issue only present in the ARM version?
