bug#19645: 25.0.50; Recent EIEIO changes broke helm: Lisp error: (cl-no-next-method helm--setup-source...

[Stefan Monnier]

It appears that you're calling helm--setup-source with an object of type
helm-type-file, but the only method that matches is a ":before" method, so
after running the before method, you get an error because there's
no primary.

IIUC the error should be `cl-no-primary-method' instead of
`cl-no-next-method' (according to
http://www.cliki.net/Proposed%20ANSI%20Revisions%20and%20Clarifications).

From what I can tell, the older EIEIO code just silently did nothing
in this case, treating the missing primary as a function that just
returns nil, but I think this is a mistake.

I'm not sure how to preserve the compatibility with this mistake.
I'll see if I can come up with something, but in any case I think you
should fix Helm by making sure there is some primary method defined in
this case as well.

     `:before' and `:after' specify execution order (i.e., when this
     form is called).  If neither of these symbols are present, the
     default priority is used (before `:after' and after `:before');
     this default priority is represented in CLOS as `:primary'.

I didn't specify :primary, because as I understand it is implicit if not
mentionned, so IIUC I have to specify it now ?

PS: Thanks to Cc me for thread related to helm so that I can fix issues.
    (Now should do as I have replied here)

It seems I have fixed the problem by indeed adding defmethod's returning nothing:

(defmethod helm--setup-source :primary ((_source helm-type-file)))

It seems this doesn't fit anymore with the current documentation and
need to be fixed with a solid explanation on how to use defmethod,
defgeneric etc...

I just pushed a change which includes a hack to preserve this old behavior.

Indeed you don't need to specify ":primary".  The problem is that for
the type of the object used in the call, there is only one method that
can be used, and it's a :before method.

Before/after methods are like before/after advice: they are executed
before/after the "main course".  In the case of methods, the "main
course" are the primary methods.  Adding an after/before method when
there's no primary, is like adding an after/before advice to an
undefined function: if you're lucky the "before" advice/method will be
run first, but when this "before" advice/method finishes, you'll
get an error that the main course in undefined.

I disagree with the "any more": it didn't fit the actual behavior
before either.

No if it's a usage error on the helm side which the older EIEIO simply
ignored, then I'd suggest not to reinstall compatibility with that older
version but with CLOS, i.e., signal `cl-no-primary-method' instead of
`cl-no-next-method'.

Oh, and I see that Thierry (the helm dev) already added primary methods
in

  https://github.com/emacs-helm/helm/commit/1eb07354f50ec26aa8be1290233696656b8dca32

So I'm closing this bug.

Still working on that one.

I'm still wondering why you'd use a :before method when there's no
primary method.

To ensure this method run BEFORE the other same methods that run for
other classes:

--8<---------------cut here---------------start------------->8---
(defclass helm-test-class (helm-source-sync helm-type-file)
  ((candidates :initform (lambda () ("foo" "bar" "baz")))))
=>helm-test-class

(helm-make-source "test" 'helm-test-class)

1) With helm-type-file `helm--setup-source' method is :before
=>
((name . "test")
 (candidates lambda nil ("foo" "bar" "baz"))
 (action ("Find file" . helm-find-many-files)
         ("Find file as root" . helm-find-file-as-root)
         ("Find file other window" . find-file-other-window)
         ("Find file other frame" . find-file-other-frame)
         [...]
 (persistent-help . "Show this file")
 [...]
 (match helm-mp-exact-match helm-mp-3-match)
 (header-line . "C-j: Show this file (keeping session)")
 (dont-plug helm-compile-source--match-plugin helm-compile-source--persistent-help)
 (matchplugin))

2) With helm-type-file `helm--setup-source' method is only :primary
=>
((name . "test")
 (candidates lambda nil ("foo" "bar" "baz"))
 (action . identity)
 (match helm-mp-exact-match helm-mp-3-match)
 (dont-plug helm-compile-source--match-plugin helm-compile-source--persistent-help)
 (matchplugin))
--8<---------------cut here---------------end--------------->8---

As you can see when the helm--setup-source method of helm-type-file is
not :before, the default slots (common to both class) of helm-source-sync
take precedence. 
The helm-test-class have to inherit from two classes, and
the helm-type-file class should overhide the default slot of the
helm-source-sync class.

Maybe there is another way to achieve this ?

I guess then adding an empty primary method is the right thing to do.
