215880 2020-08-26 23:11:15 -0700 [GTK] `webkit_web_extension_send_message_to_context` et al. abusing async semantics 2020-08-27 05:12:27 -0700 1 1 1 Unclassified WebKit WebKitGTK WebKit Nightly Build PC Linux NEW Gtk P3 Normal --- 1 mike webkit-unassigned bugs-noreply cgarcia oldest_to_newest 1683295 0 mike 2020-08-26 23:11:15 -0700 The docs for the calls `webkit_web_extension_send_message_to_context` and `webkit_web_view_send_message_to_page` state: > If you don't expect any reply, or you simply want to ignore it, you can pass NULL as callback. This is probably convenient for people programming in C, but for people programming using vala or language bindings that provide high-level constructs to handle async calls, this is impossible to do. In these cases WebKitGTK will either always emit a "Message foo was not handled" warning, or to silence the warning must always send a response back, even when not required, increasing latency. Can the warning be removed, or a proper flag introduced, or something? 1683304 1 mike 2020-08-26 23:54:18 -0700 Also `webkit_web_page_send_message_to_view`. 1683339 2 cgarcia 2020-08-27 04:05:57 -0700 hmm, I think we need to add send_with_no_reply for bindings then. 1683343 3 mike 2020-08-27 05:12:27 -0700 That would work, but it would also be convenient to be able to specify either/or with a bool or a flag or something. `send_full` maybe?
