Re: [libvirt] [PATCH] storage: Add unique UUID check for virStoragePoolObjAssignDef

Commit id '4b2e0ed6e' converted to using hash tables for storing storage pool objs by name and uuid; however, neglected to add a check to virStoragePoolObjAssignDef that the pool by uuid wasn't defined. This caused issues for the virt-manager test driver which ended up using the same UUID for a newly named pool and started having failures from adding a non unique UUID. So instead of getting a "Duplicate key", let's add a more descriptive error message indicating which pool object by name already exists using the same UUID as the pool object that is attempting to be added. Signed-off-by: John Ferlan <jferlan(a)redhat.com&gt; --- FWIW: The virt-manager test was also fixed to not use a duplicate UUID as of commit '4224b0926' in the virt-manager git repo. src/conf/virstorageobj.c | 10 +++++++++- 1 file changed, 9 insertions(+), 1 deletion(-) diff --git a/src/conf/virstorageobj.c b/src/conf/virstorageobj.c index 49fe24b28..e3acc817c 100644 --- a/src/conf/virstorageobj.c +++ b/src/conf/virstorageobj.c @@ -747,10 +747,18 @@ virStoragePoolObjAssignDef(virStoragePoolObjListPtr pools, return obj; } + virUUIDFormat(def->uuid, uuidstr); + if ((obj = virStoragePoolObjFindByUUIDLocked(pools, def->uuid))) { + virObjectLock(obj); + virReportError(VIR_ERR_OPERATION_FAILED, + _("storage pool '%s' already exists with uuid %s"), + obj->def->name, uuidstr);
