Hi!

~/.authinfo.gpg seems to be loaded automatically for TRAMP sometimes but 
not always, (dired) seems to be one command that doesn't load 
.authinfo.gpg automatically.

Steps to reproduce:
1. Open emacs with src/emacs -Q
2. Open ~/.authinfo.gpg
3. Make sure this line exists: machine ftp.dlptest.com login 
dlpuserdlpuser@dlptest.com port ftp password e73jzTRTNqCN9PYAAjjn
4. Open *scratch* buffer
5. Paste: (dired "/ftp:dlpuser@dlptest.com@ftp.dlptest.com:/")
6. Run M-x "eval-buffer"
7. Notice the request for password in the mini-buffer even though 
password is already available in .authinfo.gpg

Regards
Christian

~/.authinfo (and its different versions) are taken by the auth-sourc.el
package. Tramp is aware of it, and uses its mechanisms.

As said before, "ftp" based methods are delegated via Tramp to
ange-ftp.el. That package does not know auth-source.el, instead it has
implemented its own parsing of ~/.netrc style files.

Set ange-ftp-netrc-filename to "~/.authinfo.gpg", this should work.

Hi!

Alright, that worked. Would it be possible to make ange-ftp.el 
automatically aware of .authinfo files?
I think that would improve user experience a lot.

I can try adding support for that if it's possible

Regards
Christian

Finally, it means that ange-ftp.el uses auth-source.el. Anything goes,
but somebody must implement it. And auth-source.el has its own
interpretation of the "port" element in .netrc/.authinfo lines, which is
kind of incompatible.

I'll mark this bug report as wishlist. If nobody beats me I'll could do
it, but it will take time (too many other open requests). And for the
time being, you'll be able to apply the workaround.

> I can try adding support for that if it's possible

You could try it yourself :-)

Otherwise, I will ask you at least for tests, when the implementation
happens.

I have checked ange-ftp.el, and it does much more with the netrc file
than auth-sources.el. For example, it handles also the "account" token.

Therefore I have decided not to touch this. Instead, I have added the
following text to the Tramp manual, section "5.12.1 Using an
authentication file":

--8<---------------cut here---------------start------------->8---
   *Note* that ‘auth-source.el’ is not used for ‘ftp’ connections,
because TRAMP passes the work to Ange FTP.  If you want, for example,
use your ‘~/.authinfo.gpg’ authentication file, you must customize
‘ange-ftp-netrc-filename’:

     (customize-set-variable 'ange-ftp-netrc-filename "~/.authinfo.gpg")
--8<---------------cut here---------------end--------------->8---

If you agree, I would close this bug.

>> Christian

Best regards, Michael.

Hi Michael

Would it be a huge task extending auto-source.el to make it compatible 
with ange-ftp as well?

I think many people would appreciate that feature, but it's not really a 
bug rather a feature request

Sounds good to improve the documentation about the possible work-around

Regards
Christian

It is more complex than I expected initially, that's why I haven't
started it. And honestly, I'm rather an auth-source.el user than a
developer; I'm not very familiar with that code. That's why it might be
better if somebody else does it.

Requirements from ange-ftp.el would be at least

- Support of the "account" token.
- Support of the "default" token.
- Check of proper file permissions of "~/.netrc" or whatever file is
  specified (see ange-ftp-disable-netrc-security-check).
- Everything I have forgotten to tell here ...

The "account" token is already parsed in auth-source.el, but it is not
divided from the "login" token. Both are handled via the common keyword
:user.

The "default" token is already parsed in auth-source.el, but I'm not
sure it is used in the sense ange-ftp.el expects it. In auth-source.el
this token is expanded to an entry of its own, with an unspecified
"machine". In ange-ftp.el, the tokens of "default" are used for all
other entries, replacing missing tokens. AFAIU.

Once this is prepared in auth-source.el, I would be able to integrate it
in ange-ftp.el. That is a more simple task; I've done this already for Tramp.

> I think many people would appreciate that feature, but it's not really
> a bug rather a feature request

Agreed. Let's keep this bug (wishlist) open, maybe somebody takes over
the task. I'm Cc'ing Ted Zlatanov, the author of auth-source.el.

Hi Michael,

if you or a user could define the desired behavior as tests against
auth-source.el (we already have that set up in the core), I'd be happy
to implement them. Something like "for this call, with this
authinfo/netrc content, I expect to get back this data."

I wasn't able to deduce the desired behavior on my own, unfortunately.

Checking the permissions of the netrc file sounds like a good feature.
For a GPG file it's not so important.

MA> - Everything I have forgotten to tell here ...

There's always a few of those... :)

Hi again

I stumbled on this alternative solution from the user-guide to John 
Wiegley async.el:
https://github.com/jwiegley/emacs-async

They instead suggest using:
(setq auth-sources '("~/.authinfo.gpg" "~/.netrc"))

instead of:
(setq ange-ftp-netrc-filename "~/.authinfo.gpg")

to avoid the problem of unnecessary user-interaction, especially in the 
case of async.el since it's spawned process doesn't support 
user-interaction.

Maybe both solutions are equivalent in solving the problem that authinfo 
doesn't automatically work with .netrc files and ange-ftp doesn't work 
with .authinfo files?

I think most people just use the tokens: machine, default, port, login, 
password and they seem to work already after setting either 
ange-ftp-netrc-filename or auth-sources variable.

Can you make one of those solution a default configuration and then 
perhaps add a override for people that want to use tokens that have 
special meaning the context of ange-ftp or authinfo it they are not 
fully compatible? Maybe there could be warnings occuring when authinfo 
stumbles upon a token it doesn't support and vice versa for ange-ftp?

Regards
Christian

That's the goal of making ange-ftp aware of auth-source.el.

Yes. In general, I believe the auth-source.el solution is superior,
because you could manage all your passwords wherever you want, even in
the Gnome Password Manager (in case you use the secrets.el backend of
auth-sources).

Right.

In general, I don't want to support two different ways to handle
passwords in ange-ftp. That sounds good for trouble, because it
increases configuration complexity.

I prefer to switch to the auth-source.el solution in ange-ftp. With the
help of Ted, this shall be possible.
