[libvirt] [PATCH v3 00/12] qemu: Validate PCI controller options
Applies cleanly on top of f565321b26dfb78c1dc2d6cf5456b9b80f04c7f3. Changes from [v2]: * replace the old implementation bit by bit using a clever trick suggested by pkrempa; * don't move QEMU capability validation; * add a default: label to all switch statements as recommended by danpb. Changes from [v1]: * error out instead of silently accept invalid options; * shave quite a lot of yaks.

The input configurations set all existing options for all PCI controllers, even those that are not valid for the controller. As we implement validation for PCI controller options, we expect these test to start failing.

The input configurations set all existing options for all PCI controllers, even those that are not valid for the controller. As we implement validation for PCI controller options, we expect these test to start failing.
A noble cause, but since multiple options are being tested for multiple controllers in the same file, once you have all the proper checks in place the tests won't actually be verifying all of the negative tests - only the first failure will be noticed - if one of the others is missed, it won't "fail extra hard" or anything. Although I hate to explode the number of tests, I think if you want to have proper negative testing for every options that doesn't belong on a particular controller, then you'll need a separate test case for each combination of option and controller model. And since that would make for a *lot* of test cases if we tried to extrapolate to all other options for all other elements, I don't know that it's worth going down that rabbit hole. (What we really need is a more intelligent test rig that would allow specifying a single test with a list of variations/diffs and a note of whether the test should succeed or fail with that difference. It would end up taking the same amount of time to run the tests, but at least the amount of xml would be drastically reduced.)

A noble cause, but since multiple options are being tested for multiple controllers in the same file, once you have all the proper checks in place the tests won't actually be verifying all of the negative tests - only the first failure will be noticed - if one of the others is missed, it won't "fail extra hard" or anything.
I'm well aware of that.
Although I hate to explode the number of tests, I think if you want to have proper negative testing for every options that doesn't belong on a particular controller, then you'll need a separate test case for each combination of option and controller model. And since that would make for a *lot* of test cases if we tried to extrapolate to all other options for all other elements, I don't know that it's worth going down that rabbit hole.
So should I just drop this one, or is it still somewhat valuable to have any sort of test suite coverage for PCI controller options? -- Andrea Bolognani / Red Hat / Virtualization

Yeah, I'm just trying to be funny.

I was thinking that having this test is better than not having this test. But then I thought about what would happen if there was a regression in just a single one of these validations - the negative test would still "succeed" (i.e. "succeed in detecting a failure") because it would hit the next disallowed attribute. As a matter of fact, the test would continue to "succeed" until there was a regression in the validation of every single attribute, so that no error would be triggered. So having a negative test that has multiple examples of failures actually gives us a false sense of security - we believe that it's verifying we're catching incorrect config, but it won't actually notify us until *all* of the bad config is missed by validation. So, I think each negative test should have exactly one piece of incorrect data. That necessarily means that it's only testing for proper validation of a single aspect of a single attribute. But making this generally useful with the current test apparatus would mean a huge explosion in the number of test files, and I don't think that's practical. But if we're only testing for one out of a thousand validations, there's really not much point in it.

The default value is _MODEL_NAME_NONE aka zero, which is still part of the enumeration, so virDomainControllerPCIModelNameTypeToString() won't return NULL and no error will be raised. For pSeries guests, it will be set to _MODEL_NAME_SPAPR_PCI_HOST_BRIDGE so once again no problem there.

His efforts on switch normalization and me rebasing this series happened pretty much at the same time; more specifically, the function you're talking about was introduced in 3b1020ac805e, while my series is based on the earlier f565321b26df.

Yep, I saw his patches at about the same time as yours, and since you're respinning I thought I'd point it out.

Someday you'll learn to do what I'm doing right now - I want to add some extra validation of pci controller options, but I'm waiting to write any code until you've pushed your patches. :-)
