My overall impression is that this is a lot more complicated than I was
expecting. Can we start with something simpler to gain experience with
Travis?  And then we can add in more complexity later.

I doubt most people are running the t0204 right now. Maybe we should
start without it.

I know p4 is your area of interest, but from a project perspective, it
seems like an odd choice for the initial set of tests.

These all make sense, I guess.

What are these? I don't think we have any such Makefile knobs. These
look like variables that get used internally by the test suite, but we
shouldn't need to set them.

I'm assuming the "#" means this is commented out. Can we just drop such
cruft?

This is the default, and we don't need to specify it.

Is it a good idea to run such an expensive test?

Ditto here on the commenting.

So if I understand correctly, the point of this list is to test
alternate configurations. So compiling without curl makes some sense, I
guess. Though mostly it will just shut off a bunch off tests.

But setting platform compat knobs like this seems weird. Nobody sets
this manually. Either your platform has it, or it does not. And we are
already testing on alternate platforms to cover such things.

If there's a specific config setup of interest, it makes sense to me to
try to increase test coverage there. But it feels like you've just
picked a random laundry list of Makefile knobs and tweaked them, without
any sense of whether they even make sense together, or match the
platform.

For instance:

> +      NO_STRCASESTR=YesPlease
> +      NO_STRLCPY=YesPlease

I wouldn't not be surprised if these cause problems building on some
platforms that _do_ have these functions.

s/Perfoce/Perforce/ :)

Hmm. I wonder if we actually want to use autoconf here at all; most devs
do not use it, and Git should generally compile out of the box based on
config.mak.uname (and if it doesn't, it would be nice to know).

There may be some optional packages that autoconf helps with, though.


So overall, I dunno. I do not want to create a bunch of work for you in
splitting it up. But I'm hesitant to merge something that has a bunch of
lines that I'm not sure I understand the reasoning for. :-/

I was hoping the first cut could just be telling Travis to run "make
test", without much fanfare beyond that. Maybe that's not realistic.
