Hi,
today I have fixed in helm an eieio error according to this
bugreport:
http://debbugs.gnu.org/cgi/bugreport.cgi?bug=19552
Following Stefan advice, I have added a defalias:
(unless (fboundp 'class-slot-initarg)
(defalias 'class-slot-initarg 'eieio--class-slot-initarg))
It was working fine, but after upgrading again emacs-25, it seems eieio
raise another error:
When I try to compile helm I have:
Error: Wrong type argument: eieio--class-p, helm-locate-source
@Stefan Can you clarify what do we have to do actually to make eieio
backward compatible or if nothing have to be done on our side (external
developers) can you please fix this issue.
Thanks.

BTW, can you explain why helm needs class-slot-initarg?

It is used like this:
(class-slot-initarg class s)
where class is an object-class I get with (object-class source) and
source is a class instance.
`s' is a slot I get looping into (object-slots object) where object is a
class instance.

That doesn't explain to me *why* it needs it.
Why does Helm need to know the initarg of a slot?

Forget again to CC so I resend.
I could get rid of class-slot-initarg and now the bug is fixed in helm.
The problem is not solved though if some old external program use this.
There is also a problem now with compiled files, emacs-24.4 compiled
files are not compatibles with emacs-25 compiled files and vice-versa.

No, but that's mean that now with these recent changes all people using
helm will have errors in their helm packages when switching
emacs-version until they reinstall all;
And for sure they will not reinstall and I expect tons of bugreport in next
weeks... (I crossfingers hoping I am wrong)

That's not ideal, but it's happened with some previous releases, too.

Maybe Emacs needs a shell-level way to recompile all or some installed packages?

The approach used in Debian is that the Debian “binary” packages
contain only the source code (.el), and the respective
byte-compiled (.elc) files are produced at the installation
time, – for /each/ of the installed Emacs versions.
So, when, say, gnugo.el is installed, in addition to
/usr/share/emacs/site-lisp/gnugo.el, the following files may
also appear on the filesystem (depending on the versions of
Emacs installed on the system):
/usr/share/emacs25/site-lisp/gnugo.elc
/usr/share/emacs24/site-lisp/gnugo.elc
/usr/share/emacs23/site-lisp/gnugo.elc
…
I’m not sure whether Emacs itself handles it well when it comes
to, say, C-h f. And frankly, for backup purposes, I’d rather
prefer all that to go under /var/cache instead. (And the same
for __pycache__, etc.)

But the initarg is not the slot, so that doesn't explain why you need
the initargs?

As exlained in bug#19552, EIEIO's use of namespaces and
internal/external definitions was terribly messy (and it's still far
from ideal), so you were left having to guess whether you were allowed
to use something.
> Is its use prohibited ? :-)
Well since it's not part of CLOS, I think it should be considered
internal to EIEIO's implementation, and hence I renamed it accordingly
with the "eieio--" prefix (and slightly changed its calling convention).
> I could get rid of class-slot-initarg and now the bug is fixed in helm.
Could you give me a quick description of what you replaced it with?
> The problem is not solved though if some old external program use this.
Indeed. I can add an obsolete backward-compatible definition to handle
that, but I'd first like to better understand why it was used: maybe it
shouldn't be declared internal after all.

Files compiled with Emacs-25 are indeed not expected to work on
Emacs-24, but the other way should work (tho some of the changes in
EIEIO aren't backward compatible at their core, but so far those seemed
not to affect existing .elc files), so if it doesn't please M-x
report-emacs-bug, so we can see if/how we can fix it.

The confusion comes that slot-value as documented should use the quoted
slot (i.e 'slot) and oref should use the keyword slot (i.e :slot).
As I was using oref in first place, I was converting the quoted slot to
the keyword slot (i.e 'slot => :slot) to pass it to oref, but since I
use slot-value this is no more needed and I can get rid of this
conversion with class-slot-initarg.
Note that it seems the documentation should be updated as slot-value
support both form for slot ('slot and :slot), and IIRC oref also support
both forms, but correct me if I am wrong, I am not sure about this one,
I will check.

Yes I know, fixing all namespaces is good even if it create some
annoyances at first for us writing external packages.

As explained above it was just used to convert 'slot to :slot but well,
as we can use slot-value... but one may want to use oref and use :slot,
so it needs a way to convert this (maybe there is something else though,
enlight me).

Yes you already told me this long time ago.

Yes but it doesn't.

Ok I will in next bugreport.
Thanks for working on this.

I don't think so:
(defmacro oref (obj slot)
`(eieio-oref ,obj (quote ,slot)))
(defalias 'slot-value 'eieio-oref)
They both accept the slot name (except that one needs it quoted and the
other doesn't) and the initarg name (as an alternative name for the
slot).

Could be, indeed. I haven't looked enough at EIEIO's own documentation.

Yes right, I have ckecked too, thanks.

Probably it should be clarified:
(oref A :slot)
=> OK.
(oref A slot)
=> OK
(oref A 'slot)
=> Error: (wrong-type-argument symbolp (quote slot))
(slot-value A :slot)
=> OK
(slot-value A slot)
=> Symbol's value as variable is void: slot
(slot-value A 'slot)
=> OK

To get back to the original issue: is the conclusion that you indeed
just don't need to the functionality of class-slot-initarg, or would
that functionality be handy but you managed to work around it?

BTW, accepting the initarg instead of the slotname is actually an
extension of EIEIO: in CLOS you have to use the slot name when you call
`slot-value'.

Yes, now I use slot-value with no keyword arg for slot.

No probably you can make it internal.

Please don't, oref is also used in many places in many packages and we
will have again annoying warnings.

Yes, I know it's used extensively, just like `oset' which should also
disappear. They will have to go at some point, tho. And those warnings
are trivial to fix in a backward compatible way, since `slot-value' has
always been provided by EIEIO as well.
