tramp: how kill process

tramp: how kill process

[Paul]

Hallo people.

When on "/sudo::/root" tramp buffer, I run the following command:

(start-file-process "my-process-name" (get-buffer-create 
"*my-process-output*") "pathToProcess")

I can see it in M-x list-processes.

Unfortunatelly the following does not kill it:

C-x C-f "/sudo::/root"
M-x: (kill-process "my-process-name")

How to do it in elegant way then?

regards

`kill-process' needs a process as argument, not a process name.

M-x list-processes

Move to the process to kill, and enter "d".

Hallo Michael,
thank You for the answer.

Unfortunately, `d' is not bound to any command in *Process List* of my 
emacs.

C-h k d
d is undefined

my emacs version is:
GNU Emacs 24.5.1 (i686-pc-linux-gnu, GTK+ Version 2.24.23) of 2015-04-25 
on localhost

best regards

I don't know how elegant this is but if worst comes to worst you can get
a ps listing and then kill the associated ssh process.

  $ ps -efH | less
  /emacs
  ...look for ssh process associated with that emacs...
  $ kill 123

For example:

  $ ps -efH | less
  rwp      24638     1  0 Oct23 ?        00:03:31   /usr/bin/emacs
  rwp       5215 24638  0 13:55 pts/62   00:00:00     ssh -o ControlMaster=auto -o ControlPath=tramp.%C -o ControlPersist=no -e none despair
  $ kill 5215

I also just installed list-processes+, but no success with killing this 
process.

also M-x list-processes-kill-process (provided by list-processes+) does 
not kill it.

Michael,
I debugged list-processes-kill-process.
it does not work because (get-text-property (point) 'process) returns 
nil, when point is on the line with process to be killed.

But body contains the command `delete-process`, which You probably 
wanted to suggest me through `d' shortcut.

that one worked:)

thank YOu for Your help

best regards!

Michael,
I must unsay it.

delete-process removes process from list of processes at
  *Process List*, but process itself is NOT killed, I still can see it 
in M-x proced.

In my Emacs stanza (25.0.50), the key "d" in the *Process List* buffer
is bound to the function `process-menu-delete-process'. It's docstring
says "Kill process at point in a ‘list-processes’ buffer."

Best regards, Michael.

Re: tramp: how kill process

[Paul]

based on `delete-process` source code, it first tires to kill the 
process, then delete entry from *Process List*.

The second step is done without checking the result of first step.
Probably this is the reason of behaviour in my emacs.

either of the following commands return -1, and do NOT kill the process:
(signal-process "my-process-name" 'SIGKILL)
(signal-process "my-process-name" 'SIGINT)

I'm running these commands from /sudo::/root

Some inconsistency arises: on one hand emacs can create process with 
other user id, and on the other hand does not allow to kill it.

Is it a bug?

regards,
Paul

Unfortunatelly `process-menu-delete-process' is not present on my emacs 
(24.5.1)
