Right now in qemuxml2argv we have a proliferation of DO_*TEST* macros.
They essentially fill in data in the testInfo struct and invoke the
test function.
There's several bits of data that we want to specify for a small
subset of tests: flags, parseFlags, migrateFrom/migrateFd, gic. The
base macros need to handle these in their argument lists, and we
provide many convenience macros that fill in default values for the
less common parameters. Any time we want to add a new bit of data
though, the base macros are extended, and every caller of those
needs to be adjusted, and we are faced with the question of whether
to extend the combinatorial explosion of convenience macros which
have only a subset of options exposed.
This series adds a testInfoSetArgs which uses va_args to make these
mandatory parameters optional. The general format is:
DO_TEST_FULL(...
ARG_FOO, foovalue,
ARG_BAR, barvalue, ...)
Specifically, one of the migrate tests went from:
DO_TEST_FULL("restore-v2", "exec:cat", 7, 0, 0, GIC_NONE, NONE);
to:
DO_TEST_FULL("restore-v2",
ARG_MIGRATE_FROM, "exec:cat",
ARG_MIGRATE_FD, 7,
ARG_QEMU_CAPS, NONE);
Which may not seem directly compelling, but adding new testInfo fields
will be much easier. This will also be a base for a later series to
share the VIR_TEST_CAPS infrastructure with qemuxml2xmltest

I'd call this virQEMUCapsSetVAList(), given the type of the second
argument; the existing virCommandNewVAList() already uses this naming
scheme.
The second argument should be on a separate line.
Everything else looks good, so

...and you are merely ensuring that the macro supplies the sentinel

In fact, for this patch, you are supplying a double-sentinel, and I'm
suspecting (without reading ahead) that later patches improve things as
you add more ARG_ markers, and replacing QEMU_CAPS_LAST (which is now
identical to ARG_END, and confusingly given twice) with something more

The double sentinel is actually a requirement of the current code,
because once we see ARG_QEMU_CAPS, we pass off the va_list to
virQEMUCapsSetVList which does its own arg processing and uses
QEMU_CAPS_LAST as a sentinel. We then kick back to this while() loop,
which sees ARG_END, and completes parsing.
The ARG_END = QEMU_CAPS_LAST is a bit weird, but it handles the
DO_TEST(..., NONE) case, which translates to
testInfoSetArgs(&info, ARG_QEMU_CAPS, NONE, QEMU_CAPS_LAST, ARG_END)
Sine NONE == QEMU_CAPS_LAST == ARG_END, we finish parsing on
QEMU_CAPS_LAST. If ARG_END != QEMU_CAPS_LAST, the loop would try to
interpret QEMU_CAPS_LAST as an ARG_X value, and fail

Definitely squash in the comment :)
My only concern is that ARG_QEMU_CAPS requires you to be very
careful with its usage: not only you have to make sure you have
QEMU_CAPS_LAST as sentinel, but also you can only reasonably use it
as the last argument because QEMU_CAPS_LAST sharing the same value
as ARG_END would cause a macro like
#define DO_TEST_GIC_BROKEN(name, gic, ...) \
TEST_INTERNAL(name, "", \
ARG_QEMU_CAPS, __VA_ARGS__, QEMU_CAPS_LAST, \
ARG_GIC, gic)
to ignore the ARG_GIC argument when invoked as
DO_TEST_GIC_BROKEN("broken", GIC_V2, NONE);
I guess it's fair to expect both the developer and the reviewer to
be more careful than usual when touching this kind of dark magic
though, so including the comment is probably enough.

The name of the enum should be singular, otherwise it will look
weird when you declare a variable of the type, like...
static int
testInfoSetArgs(struct testInfo *info, ...)
{
va_list argptr;
- int ret = 0;
+ testInfoArgNames argname;
... here.

I think you should either call va_arg() with testInfoArgNames as the
second argument, or make the argname variable int and then have an
explicit cast in the switch().
[...]
+ case ARG_END:
+ default:
+ fprintf(stderr, "Unexpected test info argument");
+ goto cleanup;

+ }
+
+ ret = 0;
One extra empty line here, please.

Nope it's not necessary, I've dropped it. I think it was left over from
earlier patch state

explicit cast in the switch().
I went with the former
Thanks,

I'd put ARG_MIGRATE_FROM and ARG_MIGRATE_FD on separate lines here.

Technically speaking you should be able to leave ARG_QEMU_CAPS out
here, but it's okay if you prefer to leave it in.

The other DO_TEST_FULL instances still have it explicitly listed, so I
left it in for this one too

Probably a leftover from earlier versions.
It is unused since its introduction in:

The comment does actually not apply to DO_TEST_FULL(), which expects
a series of ARG_* and corresponding arguments rather than a list of
QEMU_CAPS_*, so you should move it one macro down - right before
DO_TEST() - instead.

It would probably have been a lot better to perform this kind of
conversion early in the series, and then gradually get rid of the
initialization for single members at the same time as support for
the corresponding ARG_* was implemented... But I'm not gonna ask
you to go back and do that :)
Note that we're also effectively changing the default value for
migrateFd from -1 to 0, but doing so doesn't cause any failures
since the value is only used when migrateFrom is "stdio", and in
all test cases where that is true we also already set migrateFd
explicitly.

Hmm I didn't notice that... but since like you say it doesn't cause test
failures, I'll leave it as is
Thanks for the reviews. I fixed all the other issues in patches 1-19 and
pushed. I'll send a v2 with patch #20+ fixed
Thanks,

I think it would be a good idea to perform some more validation on
the input here: for example we should error out if ARG_CAPS_ARCH has
been provided but ARG_CAPS_VER hasn't or viceversa, or if both
ARG_QEMU_CAPS and ARG_CAPS_ARCH+ARG_CAPS_VER have been provided,
because in both scenarios the user is probably not getting whatever
result they were expecting.

I'd prefer this as
virAsprintf(&capsfile, "%s/caps_%s.%s.xml",
TEST_CAPS_PATH, capsver, capsarch)
with TEST_CAPS_PATH being redefined as
abs_srcdir "/qemucapabilitiesdata"
of course: according to the name, it's supposed to be a path and
not a prefix after all.
Everything else looks good.

I figured ARG_ARCH/ARG_VER are ambiguous enough, the CAPS was to make
it clear this was specifically for caps file lookups

I'll handle this in a separate patch

Sure, I'll break that change out into a prep patch. v2 incoming

This macro should be called DO_TEST_INTERNAL() - you're still
running the test from it, so the DO_ prefix is fully warranted.

Right now in qemuxml2argv we have a proliferation of DO_*TEST*
macros.
They essentially fill in data in the testInfo struct and invoke the
test function.
There's several bits of data that we want to specify for a small
subset of tests: flags, parseFlags, migrateFrom/migrateFd, gic. The
base macros need to handle these in their argument lists, and we
provide many convenience macros that fill in default values for the
less common parameters. Any time we want to add a new bit of data
though, the base macros are extended, and every caller of those
needs to be adjusted, and we are faced with the question of whether
to extend the combinatorial explosion of convenience macros which
have only a subset of options exposed.
This series adds a testInfoSetArgs which uses va_args to make these
mandatory parameters optional. The general format is:
DO_TEST_FULL(...
ARG_FOO, foovalue,
ARG_BAR, barvalue, ...)
Specifically, one of the migrate tests went from:
DO_TEST_FULL("restore-v2", "exec:cat", 7, 0, 0, GIC_NONE, NONE);
to:
DO_TEST_FULL("restore-v2",
ARG_MIGRATE_FROM, "exec:cat",
ARG_MIGRATE_FD, 7,
ARG_QEMU_CAPS, NONE);
Umm, what's your sentinel value here? It is undefined behavior to call
va_arg more times than there are arguments present, but without some
sort of sentinel, you don't know when to stop calling va_arg.
The overall idea is nice, but I think you need an ARG_END sentinel.

You saw it in the later patches, but just to respond here if anyone else
is watching: there is an ARG_END but it's hidden in the macro definitions.
