Bug 276180 – WebKitDOMEventTarget.h:95: Warning: WebKit2WebExtension: invalid "scope" annotation: only valid on callback parameters

• Component: WebKitGTK
• Status: RESOLVED FIXED

[Michael Catanzaro]

Since https://gitlab.gnome.org/GNOME/gobject-introspection/-/merge_requests/477 it's no longer possible to build for GTK 3 because we have fatal introspection warnings enabled:

Source/WebKit/WebProcess/InjectedBundle/API/gtk/DOM/WebKitDOMEventTarget.h:95: Warning: WebKit2WebExtension: invalid "scope" annotation: only valid on callback parameters

Emmanuele recommends using (type gpointer) for the GCallback parameter of webkit_dom_event_target_remove_event_listener(), since it won't be called and is therefore not functioning as a callback.

Also:

"""
the `(scope async)` on add_event_listener() is also broken, because it's not an async function; but since the function is missing a GDestroyNotify to begin with, there's no way to properly annotate it
`(scope forever)` is the closest option, but that'll leak anything that tries to use it
"""

But I'll leave this broken because it's not clear whether it's fixable and this API is deprecated.
