Unless you're OK with passing a NULL here, you need to check if
'event_shutdown' is NULL at this point, since there's no guarantee that
you set the var with something else in the 'if
target==VIR_NODE_SUSPEND_TARGET_DISK'
conditional.
I'll take a guess here and say that this is unintended, thus it's best
to move this
'virObjectEventStateQueue()' call that uses 'event_shutdown' inside the
"if"
right before the cleanup label.
Thanks,

Unless you're OK with passing a NULL here, you need to check if
'event_shutdown' is NULL at this point, since there's no guarantee that
you set the var with something else in the 'if
target==VIR_NODE_SUSPEND_TARGET_DISK'

I'll take a guess here and say that this is unintended, thus it's best
to move this
'virObjectEventStateQueue()' call that uses 'event_shutdown' inside
the "if"
right before the cleanup label.
Just saw that patch 2/2 did something similar and decided to get more
informed.
Checking what virObjectEventStateQueue() does, I see that it's a wrapper to
virObjectEventStateQueueRemote(), which is a no-op if the second
argument - in this case, event_shutdown - is NULL. This means that the
usage above does not harm, which is good.
I'd still prefer to avoid using virObjectEventStateQueue() like you're doing
here, especially when it's easier to simply move the function call inside
the "if" in which you defined a non-NULL value to event_shutdown.
However, I see this same use of virObjectEventStateQueue() across the
board in test_driver.c. That said, I'll assume that this question was
already
dealt with in the first time this code pattern was introduced in the
code, and
this use is ok.
Rest of the code looks fine, so:

board in test_driver.c. That said, I'll assume that this question was
already
dealt with in the first time this code pattern was introduced in the
code, and
this use is ok.
I think not only in test_driver.c. I took a quick look and it's also
like that in some places in the QEMU driver. Plus I would say this
"pattern" is in general common in the codebase with all these free*()
functions on the cleanup sections which do the same thing - always
check for NULL first.
Additionally, if you want to check for NULL in that case you need to
do it explicitly because virDomainEventLifecycleNewFromObj might also
return NULL. This results in adding extra lines of code. Merely moving
the virObjectEventStateQueue above wouldn't change much. So, since
virObjectEventStateQueue already protects us against NULL I think
maybe it's fine to leave it like that?
In general I'm neutral to this, so feel free to alter it before merging.
Thanks for the review!
