[libvirt] [libvirt-glib] a leak in libvirt-glib
by Marc-André Lureau 02 Mar '12

02 Mar '12

Hi, In libvirt-glib, we call virStreamEventAddCallback() and give it a ref, that is supposed to be unref when the stream event is removed. But this doesn't happen! I tracked it down to: static void remoteStreamCallbackFree(void *opaque) { struct remoteStreamCallbackData *cbdata = opaque; if (!cbdata->cb && cbdata->ff) (cbdata->ff)(cbdata->opaque); Why are we checking for cbdata->cb here? That gives us a leak when taking screenshots. So far I solved it with the attached patch for libvirt-glib. I noticed it because that of a resulting process & fd leakage in the libvirtd side. It might be that the fix should be in libvirt, but anyway, the proposed patch doesn't need a libvirt depedency update and also keeps the object reference manangement at the libvirt-glib level, which is nice. -- Marc-André Lureau

[libvirt] [PATCH 0/3] add to blockrebase implementation
by Eric Blake 01 Mar '12

01 Mar '12

0.9.10 added virDomainBlockRebase as a way to expose the pending qemu 'block_stream' monitor command planned for qemu 1.1, including it's optional base parameter, but didn't wire up that part of the new API due to time constraints. RHEL 6.2 backported an earlier version of block_stream that only supports qed, not qcow2, and which lacked the base parameter). I still have plans to further improve the situation in libvirt - we need to express the backing file chain information in XML, and keep that representation up-to-date when doing snapshot and pull operations. But this series is a bare minimum to actually make use of the base parameter, with the burden on the user to pass in a valid base name.
