are the different use cases for g_autoptr vs g_autofree? We found that g_autofree is preferred for anything that uses g_malloc according to the <a href="https://developer.gnome.org/glib/stable/glib-Miscellaneous-Macros.html#g-autofree">Glib documentation</a>, and g_autoptr is for types with custom destructors. However, when using g_autoptr, we got compile errors when trying to pass the g_autoptr as an argument (the argument seems to be converted to an integer). When should we use each of these, and when should we not convert them at all? </li><li><span style="color:rgb(220,221,222);font-family:Whitney,"Helvetica Neue",Helvetica,Arial,sans-serif;font-size:16px;font-style:normal;font-variant-ligatures:normal;font-variant-caps:normal;font-weight:400;letter-spacing:normal;text-align:start;text-indent:0px;text-transform:none;white-space:break-spaces;word-spacing:0px;background-color:rgba(4,4,5,0.07);text-decoration-style:initial;text-decoration-color:initial;display:inline;float:none"><span style="font-family:Whitney,"Helvetica Neue",Helvetica,Arial,sans-serif;font-size:16px;font-style:normal;font-variant-ligatures:normal;font-variant-caps:normal;font-weight:400;letter-spacing:normal;text-align:start;text-indent:0px;text-transform:none;white-space:break-spaces;word-spacing:0px;text-decoration-style:initial;text-decoration-color:initial;display:inline;float:none"><span style="color:rgb(220,221,222);font-family:Whitney,"Helvetica Neue",Helvetica,Arial,sans-serif;font-size:16px;font-style:normal;font-variant-ligatures:normal;font-variant-caps:normal;font-weight:400;letter-spacing:normal;text-align:start;text-indent:0px;text-transform:none;white-space:break-spaces;word-spacing:0px;background-color:rgba(4,4,5,0.07);text-decoration-style:initial;text-decoration-color:initial;display:inline;float:none"><span style="font-family:Whitney,"Helvetica Neue",Helvetica,Arial,sans-serif;font-size:16px;font-style:normal;font-variant-ligatures:normal;font-variant-caps:normal;font-weight:400;letter-spacing:normal;text-align:start;text-indent:0px;text-transform:none;white-space:break-spaces;word-spacing:0px;text-decoration-style:initial;text-decoration-color:initial;display:inline;float:none">We see that some work has been done to convert files to use the Glib API.

Another area that I can offer (not listed on the issues page) is writing virsh completers. These are callback functions which are run when a user hits <TAB><TAB>, for instance: virsh start --domain<TAB><TAB> brings up a list of shut off guests. It's really regular autocompletion like we're used to from bash and/or other projects. I'd say writing a completer is more beneficial if one wants to learn how to use libvirt public APIs because that's basically what a completer callback does. I've reviewed some completer patches recently: <a href="https://www.redhat.com/archives/libvir-list/2020-September/msg00592.html" rel="noreferrer" target="_blank">https://www.redhat.com/archives/libvir-list/2020-September/msg00592.html</a> I'm happy to help, Michal </blockquote></div>
