New subject: [PATCH 1/5] test_driver: Implement virDomainDetachDeviceFlags
Introduce testDomainChgDevice for further development (just like what we
did for IOThread). And introduce testDomainDetachDeviceLiveAndConfig for
detaching devices.

There is lot of duplication here. These are already used in multiple
places and de-duplicating would help us tremendously, even more than in
the previous case with virDomainGetMessages. The lxc, libxl, qemu and
possibly other drivers would benefit from many of these, some of them
could then easily add more functionality and it would be even more
tested once we start testing these properly. It is not going to be a
trivial task to properlyd ecide where to split this and how, but I
believe you can figure out a nice, clean way. But do not hesitate to
let know if you need help with that.

What's good about the test driver is that we can support attach and
detach for all the devices. It would be nice to also have a way to test
something that is not supported, but there is no need to do it with all
of the above. It makes for example for an IOMMU as that is something I
cannot imagine being hot(un)plugged. For --config anything is possible
because it is just the XML that is being changed.

There is lot of duplication here. These are already used in multiple
places and de-duplicating would help us tremendously, even more than
in
the previous case with virDomainGetMessages. The lxc, libxl, qemu
and
possibly other drivers would benefit from many of these, some of them
could then easily add more functionality and it would be even more
tested once we start testing these properly. It is not going to be a
trivial task to properlyd ecide where to split this and how, but I
believe you can figure out a nice, clean way. But do not hesitate to
let know if you need help with that.
Yes, I was thinking if I can extract them for these drivers, but I
noticed that there may be some differences, like we have to check ACL
for some devices when using other drivers, and at least for QEMU
driver, there is no
virDomainInputDefFree(vmdef->inputs[idx]);
line in `case VIR_DOMAIN_DEVICE_INPUT:` in QEMU driver, I'm not pretty
sure whether this will lead to memory leak for QEMU or not, or it's by
design, but at least it do leak memory when using test driver. So we
may need to handle them for different drivers' case, and I am not
pretty sure whether I should extract or not, so I decide to send the
patches first. I was wondering if we can add a flag to indicate which
driver is using the function, will give it a try.

What's good about the test driver is that we can support attach and
detach for all the devices. It would be nice to also have a way to
test
something that is not supported, but there is no need to do it with
all
of the above. It makes for example for an IOMMU as that is something
I
cannot imagine being hot(un)plugged. For --config anything is
possible
because it is just the XML that is being changed.
OK, I will try to add more of them.

Not really persistent when it is called for both live and config.

So Attach will always succeed, but nothing will show up in the XML.

Same here
I thought there is no function would pass
VIR_DOMAIN_DEVICE_ACTION_ATTACH or UPDATE to this function at the
moment, so I just leave it there.

This whole thing does not have to be extracted as one function. Or it
can and there can be either flags or some callbacks, for example passed
inside xmlopt. Whatever makes it more readable, nicer etc. There will
inevitably be numerous ways to approach this and the real work is
figuring out which is the cleaner one.

OK, I will try to add more of them.
Of course first figuring out how to approach the above may make it way
easier to then add more of these.

moment, so I just leave it there.
Well yes, but then it can make it hard to find an error if someone wants
to add support for attaching and they use the function, based on the
name it sounds alright and then there is no error, it just does not
work. It's not that it is bad now, but for the purpose of
future-proofing it is beneficial to handle those cases clearly in some
way.

Sorry for that, one of them is for attach APIs, and was added by
accident, will delete it in v2.

Not many XMLs from the previous patch are used here. There could also
be some negative tests (failing on a device that does not exist for
example).
But if you de-duplicate the code then you can also go the other route
and test the generic functions without running 'virsh -c test:///...'
for every piece of functionality.

No problem, will reimplement and and more tests in v2.
