I think this should be handled by the packages, not at the eclass level.

https://bugs.gentoo.org/show_bug.cgi?id=426262#c3

The packages should either mv the configure.in to configure.ac
internally, or better yet, the maintainers should ask upstream for their
packages to fix it.

Thanks,

William

+1, otherwise we will never be able to add/unmask a newer autoconf that
doesn't look at configure.in anymore, once such a version eventually
happens.

We can always patch the eclass at that point if that is still a big
concern, but I fundamentally agree with William on this, starting point
should be fixing it upstream, so can start with a tracking bug on
affected packages.

That's a complete useless waste of time, to track some ancient packages
that don't get any upstream update anyway. The active ones have updated
it long ago. And it'd be a joke to propose last riting for the reason
of a file being named configure.in instead of configure.ac.

That determination can be made on a package-by-package basis and fixed
in ebuild if needed.

Funny thing is that packages still using autoconf 2.1* don't get
any warning and packages setting WANT_AUTOCONF to some older version
will never break...

Here's a deal: you can start filing + fixing them.

The [tracker] is already started, it was determined to add QA warning
with info on filing upstream bugs in [bug 426262] and the proper
solution is again iterated in [bug 546614], so its not like this is a
new approach that is being suggested, but sure, we should all file bugs
when we encounter them.

It seems that the proper fix to this, even for a package that won't do
the fix upstream is to use WANT_AUTOCONF in the ebuild to force the
version of autoconf you need.

No. It appears you don't know how WANT_AUTOCONF works.

 From the eclass:

# @ECLASS-VARIABLE: WANT_AUTOCONF
# @DESCRIPTION:
# The major version of autoconf your package needs

That leads me to believe that you can set WANT_AUTOCONF="someversion"
in your ebuild and your package will use that version of autoconf.

If that's wrong, it needs to be fixed and that's a different bug
entirely, but it doesn't change my position on adding this particular
change to autotools.eclass.

It is the major version, as documented. Yes, it could specify what
these valid versions currently are, as they really are:

none
2.1
2.5
latest

Currently latest equals 2.5 and is the default.

In practice, none means not to add an autoconf atom to DEPEND (even
with the default AUTOTOOLS_AUTO_DEPEND=yes) - if ebuild/eclass
inheriting autotools.eclass handles its own exact autoconf depend atom
(eautoconf will get called in eautoreconf regardless). Only main tree 
consumer of this appears to be gtk-sharp-module.eclass that adds its
own autoconf/automake atoms when needed, because eautoreconf is
conditional by variables used by that eclass and it needed autoconf
2.61 or newer, not just 2.59.

2.1 means autoconf:2.1

2.5 and latest currently means >=autoconf-2.59

Patches welcome to documentation, I suppose.


It is usually a bad sign if you need to change it away from latest for
some reason in the ebuild and ideally they'd all be the default
(latest).

There was no configure.ac before autoconf-2.50, only configure.in, and
thus a warning doesn't make sense. The real warning here is the need
for WANT_AUTOCONF=2.1


HTH,
Mart

I'm not seeing the issue with what William's suggesting -- if the
configure.in is non-trivial to just rename in the ebuild, then setting
WANT_AUTOCONF=2.1 would seem to me to be the correct course of action.
 If there's a package that has a configure.in but also needs
autoconf:2.5, well, that seems messed up and likely should be fixed in
the ebuild (or upstream) too.
