[gentoo-dev] autotools eclass - set default for WANT_AUTO*

[gentoo-dev] autotools eclass - set default for WANT_AUTO*

[Alon Bar-Lev]

Hello,

Is there any reason why not setting "latest" as default for WANT_AUTO* 
variables?

I believe that an ebuild should set these variables only if there is 
some exception.

Best Regards,
Alon Bar-Lev.

that seems like a not-too-shabby idea actually

Not sure.  Would we run the risk that working ebuilds would start to
fail when newer autotools versions arrive?

So what do you suggest of putting? Current revision?
And we can drop the "latest" support... right?
But then we should handle old ebuilds that use old auto*.
I think a specific version should be specified only if something
breaks with latest,
thus it should be the default.

Because then stuff will "magically" work in stable, and break in ~arch, and 
you won't know why it's happening.

Instead if you follow the procedure (set the variables) you know that you 
asked for latest version, and you'll be able to check what the problem is.

Yes, I expect automake 1.11 to break even more, as they are coming around.

which is no different from the current behavior ... we're sticking "latest" 
into all of our ebuilds now

besides, if code doesnt work with the latest autotools, it should be fixed ... 
it should not force older versions

what does it matter if all of the ebuilds declare latest or the eclass 
declares latest ?

Weren't we going to allow declaring "1.10 1.9" soon, so that we could stop 
using "latest" ?

no, that was not the reason at all for the new syntax

the reason was so in the *eclass* you could translate latest to "1.10 1.9" and 
drop the need of executing that helper function in local scope

Right, but I thought the other one, too..

Well, I suppose it would do little harm at this point to default to latest, 
and be done with that, and allow specifying 1.10 1.9 in the future (when mips 
and ppc would keyword the wrapper) so that we cover that base too.

why not just get rid of the idea of "latest" ?  is there a scenario where 
autotools would be inherited but not actually used/added to DEPEND ?  i guess 
that's what this all comes down to really ...

If autotools were to be inherited by an eclass, and left to the eclass users 
to depending on the correct versions, I'd say.

Although for kde I simply preferred to depend always and be done with that (as 
half of KDE packages anyway already use them).

Well.... What is the verdict?
1. Add default.
2. Explicit specify version in WANT_AUTO*.
3. Continue adding WANT_AUTO*="latest" everyplace.

we've gone this route ... if/when an issue comes up where someone is 
inheriting autotools but they're using it conditionally, we'll revisit this

autotools.eclass:
[[ -z ${WANT_AUTOCONF} ]] && WANT_AUTOCONF="latest"
[[ -z ${WANT_AUTOMAKE} ]] && WANT_AUTOMAKE="latest"

Thanks!
After you commit this, I will go over all my packages and remove the
latest setting.

seems Diego is two steps ahead ... set the vars to "none" :)
