#1232007 — Bug#1095296: heimdal-clients: invoking klist.heimdal etc doesn't work

Package: heimdal-clients
Version: 7.8.git20221117.28daf24+dfsg-2

$ /usr/bin/klist.heimdal
klist, list
	klist
kgetcred
	kgetcred
kswitch, switch
	kswitch
kvno
	kvno
copy_cred_cache
	copy_cred_cache
help, ?
	help [command]

The problem here is that kuser/heimtools.c:command_alias() doesn't know
to strip the .heimdal suffix. (Neither does setprogname() in libroken,
which only strips the .exe suffix if present.)

Invoking klist.heimdal is occasionally useful when /usr/bin/klist points
to klist.mit (OK, I backported krb5-user from trixie) and one wants to
use Heimdal-specific features like the -T flag.

FYI: I created a thread on debian-devel on this issue:
https://lists.debian.org/debian-devel/2025/02/msg00100.html

In particularly, see the last part of
https://lists.debian.org/debian-devel/2025/02/msg00107.html

I responded to this, but my response hasn't hit the archives yet.

If one wants to force people to use "exec -a klist klist.heimdal" one should probably document this somewhere (in the man page). Perhaps more importantly, not all shells support the -a option to exec. (Neither dash nor tcsh seem to; bash does, I haven't checked ksh or zsh.)

I can contribute a patch to the command_alias() function if you wish.

Ideally something like this wwould go upstream, not in Debian. But I am
guessing that any changes here would have to be Debian specific for the
names chosen by the Debian package.

I wOuld be willing to have a look at any such patch if you are happy to
contribute it.
