Merge code in storage_driver.c and test_driver into virstorageobj to
count the number of volumes/pools, to return a list of names, return
the collected list of objects for volumes/pools. For volumes, that's
moved code, while for pools that's just changing the export API to
take an address of 'devobjs' to follow other usages. I also added
code to converge the FindBy{UUID|Name}
FWIW: This is part of the common driver objects code I've been working
through. I figured I will post each driver separately rather than one

New subject: [libvirt] [PATCH 1/7] storage: Introduce virStoragePoolObjNumOfVolumes
Unify the NumOfVolumes API into virstorageobj.c from storage_driver and
test_driver. The only real difference between the two is the test driver
doesn't call using the aclfilter API.

This will not fly. I mean, it will as long as privpool != NULL at this
point. You need to keep the check for privpool before calling Unlock()
over it because Unlock() does not handle NULL well. Alternatively, you
can return directly if testStoragePoolObjFindByName() fails (instead of
goto cleanup).

They are not const in any way.
"char **const names" is how this has been defined since before I touched
it! It'd need to be something changed in many more places.

Again, this doesn't look right. Should VIR_STRDUP() fail, nnames is

True, but it does follow from whence it came w/ variable name changes. I
will change it though.
Guess this also trivially ;-) needs to be adjusted in the (now pushed,
<sigh>) nodedev changes as well...

This will not fly. I mean, it will as long as privpool != NULL at this
point. You need to keep the check for privpool before calling Unlock()
over it because Unlock() does not handle NULL well. Alternatively, you
can return directly if testStoragePoolObjFindByName() fails (instead of
goto cleanup).
Oh right - good catch. I'll return -1 if the ObjFindByName fails
instead (similar to how the storage_driver code does things)

New subject: [libvirt] [PATCH 5/7] storage: Introduce virStoragePoolObjGetNames
On 04/06/2017 01:48 PM, John Ferlan wrote:
Mostly code motion to move storageConnectList[Defined]StoragePools
and similar test driver code into virstorageobj.c and rename to
virStoragePoolObjGetNames.
Also includes a couple of variable name adjustments to keep code consistent
with other drivers.

Merge code in storage_driver.c and test_driver into virstorageobj to
count the number of volumes/pools, to return a list of names, return
the collected list of objects for volumes/pools. For volumes, that's
moved code, while for pools that's just changing the export API to
take an address of 'devobjs' to follow other usages. I also added
code to converge the FindBy{UUID|Name}
FWIW: This is part of the common driver objects code I've been working
through. I figured I will post each driver separately rather than one
