Subject: 29.2; Eshell: completing Tramp remote hosts no longer works
Date: Mon, 4 Mar 2024 18:43:32 -0500

Hi folks,

In an Eshell session, completing the names of Tramp remote hosts no
longer seems to work. This is a regression from Emacs 29.1.

Recipe:

1. Emacs -Q.
2. M-x eshell.
3. Type "cd /scp:".
4. Type TAB.

Observe that no completions are offered.

If you try the same thing in Emacs 29.1, you will be offered completions
based on the contents of your ssh configuration files.

Thanks for your help!

Thanks for the report. I believe this is the same as bug#65356, though 
that bug suggests it was a new feature, rather than a fix for something 
that broke. In any case, I tested it in Emacs 30 and all seems well there.

It would be interesting to see what commit regressed this between 29.1 
and 29.2 though...

Likely, it isn't a single commit. Tramp's method, user name and host
name completion has been reworked between Emacs 29.1 (Tramp 2.6.0.29.1)
and Emacs 29.2 (Tramp 2.6.2.29.2). See bug#37954, bug#51386, bug#52758,
bug#53513, bug#54042 and bug#60505.


Best regards, Michael.
