[gentoo-dev] base.eclass

Hi all,

I'd like just to receive a short clarification about the 'status' of
base.eclass: Is this eclass expected to be available everywhere, i.e.
should each eclass make sure it imports and incorporates it. Or is it
just an eclass like the others and ebuilds should make sure they inherit
it if needed?

In my special case, I discovered that I cannot rely on 'PATCHES' being
honored and hence have to introduce something like:

src_prepare () {
   epatch "some.patch"
   distutils_src_prepare
}

And, imho, this is just noise -- having PATCHES=( "some.patch" ) would
be clearer :)

Thanks,
René

base.eclass is a historical mistake, from before the design of eclasses
was fully figured out and moved into the package manager. Unfortunately,
rather than letting it die, people keep putting things in it and using
it...

I think it would be a good idea to remove the second sentence of the
description, which is clearly false.

# @DESCRIPTION:
# The base eclass defines some default functions and variables. Nearly
# everything else inherits from here.

No. It is unmaintained, has serious design flaws and it simply should
not be used anywhere. At least in EAPI != [01].

Thanks for the clarification. As Mike already mentioned, one should
probably change the ebuild description to reflect just that fact.
(Because at the moment it just says the complete opposite.)

And, if we are supposed to stop using it, it should print some kind of
warning to remember developers to drop its usage

what is the PATCHES=() replacement in new eapis? (mainly why i use
base.eclass more and more these days)

That's what I used:

[[ ${PATCHES} ]] && epatch "${PATCHES[@]}"

and ? thanks, I can read the code :)
are you suggesting people to duplicate the code ? this is in no way a
replacement...

Please clarify this. 

A lot of (inheriting eclasses and) packages depend on features provided by 
base.eclass (e.g., PATCHES), which are pretty neat and which I would sorely 
miss. So I would certainly object to deprecating base.eclass, unless its 
relevant functionality is only moving to a better place.

base.eclass is randomly exporting non-requested, non-wanted phase
functions colliding with other inherited eclasses. It's just
the lexical order of inherits what stops mayhem from happening.

In other words, base.eclass is only suitable if you are expecting to
export *all* phase functions which simply doesn't happen in eclasses.

For example, if distutils used base eclass, every VCS eclass inherited
before it would be ignored (due to src_unpack() redefined to default
one for no good reason).

There are tons of eclasses "randomly" exporting phase functions. That
is not the problem. The problem is that other eclasses inherit
base.eclass. Only that leads to this mess.

Then you should ask for EAPI support for PATCHES, or write the code
manually, or put the code in a small eclass that just does that.

But note that the Council has voted against having either arguments or
global scope variables to enhance default phase functions.

yet base.eclass supports arguments for base_src_install passed to 'make 
install'

and council voted against moving this to the PM

so what ciaranm said is very true, people just refuse to let it become 
useless

Perhaps you should view the Council's vote as advice that passing
arguments that way is unpopular and unlikely to endear you to your
fellow developers.
