Hi,

With this patch, passwords won't appear in the lossage or the dribble
file.

We already have a facility for this, see 'no-record' in the
description of unread-command-events in the ELisp manual.  Please see
if you can use that instead.

And if you must have a variable, I'd prefer to un-obsolete
inhibit--record-char, which was once used for this purpose, but no
longer is, and restore the code in keyboard.c which supported it.

Thanks.

Ok but I don't quite understand how unread-command-events works. For
instance, if I put this code into `read-passwd':

--8<---------------cut here---------------start------------->8---
(setq-local unread-command-events
            (mapcar #'(lambda (x) (cons 'no-record x))
                    (listify-key-sequence "mypassword")))
--8<---------------cut here---------------end--------------->8---

It will prefilled (and not recorded) at prompt with "mypassord" but I'd
like to be able to type the real password that I don't know in
advance. In `read-passwd', the password is read with `read-string' that
is C code… Anyway, can someone explain what is the purpose (and usage)
of unread-command-events?

I was not aware of this code. But yes, maybe we should do that.

Thanks.

Hi,

So I digged into the log and found that `inhibit--record-char' was
obsoleted in bd5c740419.

The reason seems to be that "quail.el" was the last user of this
variable and use it to inhibit a second recording after the first
one. AFAIU, quail.el now have function (quail-add-unread-command-events)
that put a copy of those events with 'no-record into
unread-command-events to have this behaviour.

I was not able to do the same when reading password (there is just one
read_char involved), so as Eli suggested, I choose to un-obsolete
`inhibit--record-char' and use it in `read-passwd' only.

Thanks.

Stefan, do you see any way of producing (no-record . CH) from "normal"
input APIs, for reading input that shouldn't be echoed or recorded?

If not, we will resurrect that variable and use it instead.

No: the (no-record . CH) is specific to `unread-command-events`, i.e. to
events that are "synthesized" (typically from previously read events)
whereas those events that come from the keyboard get added directly to
the lossage buffer before we have a chance to do anything about it.

Sounds good to me.

OK, thanks.

The next question is: do we want to enable this by default and in a
way that users cannot have the previous behavior back?

In any case, this needs a NEWS entry, I think.

I think that having this as a default is a good thing™ (no more clear
password in lossage).  About being able to revert this behaviour, I know
I won't use it but maybe it has some use case with the dribble file: do
people use the dribble file as some automation tool for example?

Ok, I'd one to this patch when we have decide the default and if it
needs a user option.

I'm strongly in favor of it being enabled by default, yes.
I think most people expect that their passwords aren't trivially
available in clear from the lossage.

> and in a way that users cannot have the previous behavior back?

I'd think being able to redefine `read-password` is sufficient, because
it should really be extremely uncommon to need your password to appear
in lossage and/or a dribble file.

Dribble file is a debug facility, and quite an important one at that.
Lossage is also a troubleshooting facility, at least in some of its
uses.

So asking that people redefine functions for that is too harsh,
IMNSHO.  What's the harm from having a variable that people could flip
if they need it?

Sounds like having this on by default is what people want.  But we
need a knob to revert to the previous behavior, and we need a NEWS
entry.  Could you please prepare an updated patch with those two
additions?

Thanks.

Yes, there should be an option to revert it, otherwise it'll break my
"workflow"[1].

And I think it would be useful to record non self-insert keys (like
"M-x") while typing password, since those key aren't related to the
password.

Hi,

I've just tried and this patch does just that: you can "M-x something"
in the middle of entering a password and the execute-extended-command
will be recorded but not the password.

Eli, Stefan, should I try to have a custom to revert this back?  What
would be the name of such custom?  record-password?

Yes.  And a NEWS entry, please.

I think it would be better to have a more general name, in case we
would want to exempt more stuff from being recorded.  Something like
record-all-keys, perhaps (with an explanation in the doc string that
currently it only affects password entry)?

Thanks.  Two minor nits (but you don't have to submit another patch,
this will be fixed when installing):

                   ^^^
We use 'nil' (lower-case, without the quotes).  Also, the "now" part
is redundant.

The first line of a doc string should be a single complete sentence
(for the benefit of help commands, like 'apropos', which only show the
first lines).
