2020-07-27processes: 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'. Ludovic Courtès
2020-06-28processes: Write to $PAGER....* guix/ui.scm (with-paginated-output-port): Export. * guix/scripts/processes.scm (guix-processes): Use it instead of writing directly to (current-output-port). Ludovic Courtès
2019-04-29processes: 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'. Ludovic Courtès
2019-04-29processes: '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'. Ludovic Courtès
2018-10-29Add 'guix processes'....* guix/scripts/processes.scm, tests/processes.scm: New files. * Makefile.am (MODULES): Add the former. (SCM_TESTS): Add the latter. * po/guix/POTFILES.in: Add guix/scripts/processes.scm. * doc/guix.texi (Invoking guix processes): New node. (Invoking guix-daemon): Reference it. Ludovic Courtès
