Hi again

I stumbled on this alternative solution from the user-guide to John Wiegley async.el:

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?

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.

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