2020-07-27 | processes: Allow 'less' to properly estimate line length.•••Until now, the first few lines in the output of 'guix processes' could
disappear in 'less'.
* guix/ui.scm (call-with-paginated-output-port): Add #:less-options
parameter and honor it.
(with-paginated-output-port): Allow callers to pass #:less-options.
* guix/scripts/processes.scm (guix-processes): Pass #:less-options to
'with-paginated-output-port'.

* guix/scripts/processes.scm (guix-processes): Use it instead of writing
directly to (current-output-port).

2019-04-29 | processes: Gracefully handle daemons without clients.•••Fixes <https://bugs.gnu.org/34716>.
Reported by Mark H Weaver <mhw@netris.org>.
The problem could be reproduced by running, on one hand:
sh -c 'exec -a guix-daemon sleep 777'
and on the other hand:
guix processes
If there is no process with PID 777, 'guix processes' would barf as it
stumbles upon a <daemon-session> record whose client is #f.
* guix/scripts/processes.scm (daemon-sessions)[child-process->session]:
New procedure, with lambda formerly passed to 'map'. Handle #f returns
from 'lookup-process'.
Call 'child-process->session' within 'filter-map', not just 'map'.

2019-04-29 | processes: 'process-open-files' ignores disappeared /proc/PID/fd entries.•••Previously, 'process-open-files' would throw ENOENT if an entry had
vanished after the 'scandir' call and before the 'readlink' call.
* guix/scripts/processes.scm (process-open-files): Catch ENOENT errors
from 'readlink'.
