Bug#461247: dpkg: update-alternatives --test doesn't work as advertised

2008-01-17 Thread Toby Speight 
Package: dpkg
Version: 1.14.7
Severity: important
File: /usr/sbin/update-alternatives

/[ update-alternatives --help ]
| Options:
|   --test   don't do anything, just demonstrate.
\

But when I tried using --test to check my --remove-all command, I got
no output, and I discovered that the remove-all had actually been
performed.   Luckily, I had got my command right...

Confirmed:
$ grep testmode scripts/update-alternatives.pl 
my $testmode = 0;
$testmode= 1;

So it looks like this never got implemented... this was already the case
in dpkg 1.1.4 in 1996 (this is as far as I can go in the history).

Thus I suggest to simply remove that option altogether from the script and the
manual page.

Cheers,

I was about to add 'not yet implemented' in the --help output to sync
it with the manpage, but thinking how this could be implemented I've
to say I agree we better just remove the option. The whole script
depends on the files it has changed/removed/symlinked during the whole
execution.

So I'll just do that.

regards,
guillem
