Add a function named virDomainObjCheckIsActive in src/conf/domain_conf.c.
It calls virDomainObjIsActive, raises error and returns.
There is a lot of occurence of this pattern and it will save 3 lines on
each call. Knowing that there is over 100 occurences, it will remove 300
lines from the code base.

I was just looking at this patch. Yes it is incomplete but I think that
was the point. Give upstream taste what the patch looks like before
diving in and changing all those 108 occurrences (I did change them
locally).
The patch looks good to me, but as Jan suggests, you can break this big
change into smaller (=easier to review) patches. In the first you can
just introduce the function. And then have patch per each folder.
Alternatively, you can write a small semantic patch [1] and use that to
generate the diff. But this is rather advanced stuff.

I agree with the intention of the patch and the comments, I'd maybe change the
name slightly --> virDomainObjCheckActive (instead of *IsActive) or even
something that emphasizes a bit more that it will report error on inactive, so
that the caller doesn't have to care about that anymore - from the top of my
head "virDomainObjReportInactive"...

It's right, it's one of the BiteSizedTasks proposed to begin with [1]
and it's asked to do it in two times.
First do a small patch and have it review and then change all the occurences.
I'm sorry I should have mentioned it.

I agree with the intention of the patch and the comments, I'd
maybe change the
name slightly --> virDomainObjCheckActive (instead of *IsActive) or even
something that emphasizes a bit more that it will report error on inactive, so
that the caller doesn't have to care about that anymore - from the top of my
head "virDomainObjReportInactive"...
I'm going to do that. I think virDomainObjCheckActive is a good name.
For the virDomainObjReportInactive, I have the feeling that, by
reading the name,
people may expect that the function will return 0 if there was an error.

I'll take a look into coccinelle. It may take a bit more time thought.

You need to add one more space of indentation in the three lines above.
