bug#55555: 28.1; Tramp prompting for password even with an existing .authinfo.gpg file

[Thierry Volpiatto]

This is not happening up to Emacs-28.1, this starts happening recently
from emacs-29+.
It asks also to save password in authinfo file when entering password.
Really annoying.
Thanks.

bug#55555: 28.1; Tramp prompting for password even with an existing .authinfo.gpg file

Do you use a "sudo" connection? There has been a change in the .authinfo
entry, see etc/NEWS from master:

--8<---------------cut here---------------start------------->8---
*** Proper password prompts for methods "doas", "sudo" and "sudoedit".
The password prompts for these methods reflect now the credentials of
the user requesting such a connection, and not of the user who is the
target.  This has always been needed, just the password prompt and the
related 'auth-sources' entry were wrong.
--8<---------------cut here---------------end--------------->8---

And the Tramp manual says

--8<---------------cut here---------------start------------->8---
   For the methods ‘doas’, ‘sudo’ and ‘sudoedit’ the password of the
user requesting the connection is needed, and not the password of the
target user.  If these connections happen on the local host, an entry
with the local user and local host is used:

     machine HOST port sudo login USER password secret
--8<---------------cut here---------------end--------------->8---

> It asks also to save password in authinfo file when entering password.
> Really annoying.

See the Tramp manual:

--8<---------------cut here---------------start------------->8---
   If no proper entry exists, the password is read interactively.
After successful login (verification of the password), Emacs offers to
save a corresponding entry for further use by ‘auth-source’ backends
which support this.  This can be changed by setting the user option
‘auth-source-save-behavior’ to ‘nil’.
--8<---------------cut here---------------end--------------->8---

Ok thanks, will try soon to modify authsource file.

Is this compatible with previous emacs versions (at least 28)?

I use

    default port sudo login root password xxxxx

since years now so I was surprized this stopped working suddently.

Ok thanks for this, I don't want anything writing in this file.

Thanks.

Unfortunately this is not working, thus it is crashing emacs.
Will try to investigate later.

Thanks.

Ah! ok it is working now with my username and not "root" as before.
Anyway it should not crash emacs when an entry in authsource is wrong,
it should fail more gracefully.
To reproduce replace your username in authinfo by "root" and try /sudo::

PS: Emacs first freeze and then I have to "killall emacs" several times
to get it killed effectively.

It isn't compatible. But for a while, using both Rmacs 29 and Emacs <29,
you could keep both entries in .authinfo.gpg.

I cannot reproduce this. Could you pls check whether this happens also
for you running "emacs -q"? Yes, a small "-q"; with "-Q" Tramp ignores
the auth-source library.

Best regards, Michael.

Yes, pls do. Perhaps it would be worth a new bug report then.

Closing *this* bug.
