I was hoping to quickly re-send the qemu_driver cleanups I've sent some time ago, now using Glib. I started by attempting to change the first VIR_AUTOUNREF() call in qemu_driver.c to g_autoptr(), which happens to be a virStorageSourcePtr type, then I realized that it wasn't that simple.
It should be that simple with this commit: commit 667ff797e8eb8d82f30ab430216a8d2eef6b915a Author: Daniel P. Berrangé <berrange@redhat.com> Date: Fri Oct 4 17:14:10 2019 +0100 src: add support for g_autoptr with virObject instances we should be able to use g_autoptr for any virObject, without having to lock-step convert to GObject. What actual problem did you find ?
Following up the instructions found on commit 16121a88a7, I started the conversion. Then 'make check' started to fail because some calls to virObjectRef/virObjectUnref were still remaining in the code, messing up stuff related with mirrorChain in qemu_blockjob.c. Turns out it was easier to burn through all the instances and change them to use GLib.
Yes, if you convert from virObject to GObject, you *must* convert all virObjectRef/Unref calls at that time.
This is being sent as RFC because x-I am aware that docs/hacking.html mentions that we shouldn't mix up certain GLib macros with Libvirt ones, thus I am uncertain of whether I have messed up or not. 'make check' works, did a few sanity checks with libvirtd as well.
Yes, the need to not mix g_auto* with VIR_AUTO*, is why I did commit 667ff797e8eb8d82f30ab430216a8d2eef6b915a to let you use g_autoptr with virObject, without first converting to GObject.
