Since four years we get the message
Caution: No free/unref found for (g_enum_complete_type_info)
Caution: No free/unref found for (g_flags_complete_type_info)
whenever we install the Nim GTK bindings, so maybe it is time to investigate the issue.
There must be something special about these two functions, as all the thousand other ones are fine.
The issue is about GTypeInfo deallocation in https://developer.gnome.org/gobject/stable/gobject-Enumeration-and-Flag-Types.html#g-enum-complete-type-info.
As I was not able to find a free() function I just visited gitlab:
My english is not that good, but may
@info: (out callee-allocates)
be wrong. May it be caller?
Yeah, I think you are correct - those arguments should be
caller-allocates. For example,
g_type_module_register_enum certainly uses a stack-allocated
GTypeInfo and asks
g_enum_complete_type_info to fill it in. Paging @pwithnall.
Indeed. Please feel free to submit a merge request to update the annotations
These functions also seem like something that shouldn’t get directly exposed in bindings like this. It’s part of the dynamic/plugin type machinery and that’s going to need properly integrated manual bindings to be usable nicely and safely.
