(That was 7.5 years ago.)

What followed was a discussion about how Tramp should use 'add-function'
instead of 'set-process-sentinel', IIUC.  Is this still an issue, or has
the situation changed since?

There is a real problem with the default filter/sentinel, indeed.
Basically, add-function is a mechanism that allows combining functions
onto a "single function spot", so it provides the tool we need.

But another problem remains: for historical reasons (and for
convenience), the default filters/sentinels don't "do nothing".  So in
many cases packages want to *replace* the default rather than extend it.
`set-process-filter' works well for those, until another package comes
along which needs to interact with it.  Saying "use add-function"
doesn't really solve this problem, because we'll just replace

  (set-process-filter PROC FUN)
with
  (add-function :override (process-filter PROC) FUN)

which, just like set-process-filter, will override not just the default
filter but other filters added via add-function as well.

I haven't thought about how to really solve this problem.  I'm open
to suggestions.

I don't have a good answer yet, sorry.

In practice, your proposal means to throw away `set-process-sentinel'
(and `set-process-filter'). Since the default functions are already
enabled, in most cases one shall use `add-function' instead. Which is
more complicate.

Do we want such a radical change? Your wording, you have applied in
processes.texi, sounds different.

(I don't oppose completely, I just want that we understand and agree
such a change.)

Maybe. But Tramp cannot know who is using it. It just offers (its own
implementation of) very primitive functions, that's it. And it cannot
know, whether the calling library is doing its settings before or after
Tramp's setup.

That's what this bug report is about.

That's a good question.  So far it works well when you know enough of
the various places that want to set a filter, so you can make sure only
one of them uses set-process-filter (and does it before the others).

There are already `internal-default-process-filter' and
`internal-default-process-sentinel'. They must be replaced, of course,
when a new filter/sentinel is added.

> Then instead of using `set-process-filter' one could use
> (add-function :whatever (process-filter process) ...)

Nope. One would need to change all places those functions are called. I
believe it is simpler to modify `set-process-filter' and
`set-process-sentinel'.

What about having a default sentinel/filter for all process that does
nothing (just a placeholder)?

Then instead of using `set-process-filter' one could use
(add-function :whatever (process-filter process) ...)

Reading your text, I wonder how one should implement this. Usually, one
doesn't know which other library intends to set a filter or a process.

In stock Emacs, there are 43 files with calls of `set-process-filter',
and 53 files with calls of `set-process-sentinel'. In the elpa branch,
there are 4/4 additional such files. All those places must be adapted,
checking whether there could be several filters or sentinels.

Wouldn't it be more consistent to modify `set-process-filter' and
=C2=B4set-process-sentinel' to take care, when several filters or sentinels
are added to a given process? Both functions could be equipped with an
optional argument WHERE, which has the similar meaning as in
`add-function'. Maybe just :before, :after and :replace shall be
allowed, and one of them (:after?) could be the default.

AFAIK add-function does that.

Indeed, the protocol should be universally enforced.

Yes. But all of the sentinels (or filters) must play the same game
then. When Tramp's sentinel is the first one being activated, it
shouldn't be thrown away by a `set-process-sentinel' call from another
library. We don't know in advance, in which order sentinels are
installed for a given process.

Best regards, Michael.

Ah, thanks. I wasn't aware of this use case. However, shouldn't this be
propagated further? The Elisp info pages do not mention this use case,
when speaking about `set-process-filter' or `set-process-sentinel'.

Anyway, I'll try to rewrite Tramp's process filters and sentinels next
days. As usual, the crucial point will be backward compatibility ...

Or a protocol: if you install a sentinel, and another one already

Not true any more: Emacs-24.4's `add-function' was invented in response
to this specific request (or maybe it was for set-process-filter, but
the point stands).

The problem seems to be more general. Emacs does not support to have
several process sentinels for a given process. If several sentinels are
declared for a process by ?`set-process-sentinel', they compete for
being attached to the process. And the last one wins.

So we need to support several sentinels per process. Maybe this exist
already, but I'm not aware of such a mechanism.
