add identifying client info to 'xpra list' output

[karlkleinpaste]

Is your feature request related to a problem? Please describe.
The output of xpra list doesn't tell me anything useful about clients, merely that they exist.

Describe the solution you'd like
In this output...

$ xpra list
Found the following xpra sessions:
/home/karl/.xpra:
	LIVE session at :27
	LIVE session at :73
/run/user/5271/xpra/clients:
	LIVE session at :1439094
	LIVE session at :1446093
	LIVE session at :196224
	LIVE session at :199091
	LIVE session at :199093
	LIVE session at :199098
	LIVE session at :2419503
	LIVE session at :2419627

... it would be helpful if the clients would include some part of the client info, such as :86 or ssh://remote/XX.

Otherwise I must ps wu 1439094 just to learn what that client is about.

You could just run:

xpra info :1439094

And as of 61d2004, just look for endpoint.

I would rather not make xpra list slower than it already is.

[karlkleinpaste]

Well...OK. I would have preferred a builtin bit. As it is, I've just written a script xplist:

#!/bin/bash
xpra list 2>&1 |
(
    while read l ; do
	if [[ ! "$l" =~ xpra/clients: ]] ; then
	    [[ "$l" =~ LIVE ]] && l="	$l"
	    echo "$l"
	else
	    echo "$l"
	    break
	fi
    done
    while read l ; do
	if [[ ! "$l" =~ LIVE ]] ; then
	    echo "	$l"
	else
	    p="`echo $l | cut -d' ' -f4`"
	    endp="`xpra info $p | grep endpoint | sed 's/endpoint=//'`"
	    echo "	$l	$endp"
	fi
    done
)

Result:

$ xplist
Found the following xpra sessions:
/home/karl/.xpra:
	LIVE session at :28
	LIVE session at :73
/run/user/5271/xpra/clients:
	LIVE session at :17050	:28
	LIVE session at :18005	:73
	LIVE session at :21541	chqkkleinpa1:22
	LIVE session at :21542	cdcvdr9ebu01:22
	LIVE session at :428093	ph:7887
	LIVE session at :430062	godiva:7887
	LIVE session at :433233	micro:7887
	LIVE session at :440572	minor:7887

I could have done the endp calculation with ps $p | tail -1 | sed -e 's/.*attach //' -e 's/ .*//' but the endpoint thing is as good, I suppose.

Belated observation...

The xpra info $p version doesn't include the $DISPLAY in use at the client. So I've gone to the alternate using ps:

endp="`ps ${p#:} | tail -1 | sed -e 's/.*attach //' -e 's/ .*//'`"

[ Just leaving crumbs behind for anyone else who might ask similar questions. ]

As of the commit below, you can also do:

$ xpra info :15716 | egrep "session-type|display"
session-type=Wayland client
display=wayland-0

Not tested with MS Windows and MacOS clients, but these should also be showing things like MacOS client.

@karlkleinpaste how about dc9882f:

$ xpra list-clients
Found the following 1 xpra client sessions:
/run/user/1000/xpra/clients/fedora-27154:
	LIVE Wayland client on 'wayland-0' connected to 'tcp://127.0.0.1:10000/'
