So far we didn't place spaces between the box drawing chars and the
values next to them. Let's be consistent here.
(Or to turn this around: if we really want to place a space there we
probably should do that in all our tree outputs, not just here...)
It's probably a good idea to minimize the number of field names to show
in the "systemctl status" output, in order to make them useful as a
guide for the reader how things are "grouped". This patch moves
information about the used socket technology to the end of the output
lines in brackets, rather than into the field names. This turns the used
socket technology into what it is -- peripheral meta information --
instead of something that was at the core.
New output:
systemd-journald.socket - Journal Socket
Loaded: loaded (/usr/lib/systemd/system/systemd-journald.socket; static)

Instead of outputting "5h 55s 50ms 3us" we'll now output "5h
55.050003s". Also, while outputting the accuracy is configurable.
Basically we now try use "dot notation" for all time values > 1min. For
>= 1s we use 's' as unit, otherwise for >= 1ms we use 'ms' as unit, and
finally 'us'.
This should give reasonably values in most cases.
code in src/shared/macro.h only defined MAX/MIN in case
they were not defined previously. however the MAX/MIN
macros implemented in glibc are not of the "safe" kind but defined
as:
define MIN(a,b) (((a)<(b))?(a):(b))
define MAX(a,b) (((a)>(b))?(a):(b))
Avoid nasty side effects by using our own versions instead.
Also fix the warnings derived from this change.
[zj: - modify MAX3 macro to fix warning about _a shadowing _a,
- do bootchart/svg.c too,
- remove unused MIN3.]
gcc thinks that errno might be negative, and functions could return
something positive on error (-errno). Should not matter in practice,
but makes an -O4 build much quieter.
Distributions that never shipped upstart do not have
"telinit" in /lib/upstart/..
Defaults to /lib/upstart/telinit so there is no change
for systems existing installs.
After that functions which add matches, show_journal_by_unit
and show_journal_by_user_unit, become nearly identical, so
I merged them into one function.
This introduces a new static list of known attributes and their special
semantics. This means that cgroup attribute values can now be
automatically translated from user to kernel notation for command line
set settings, too.
This also adds proper support for multi-line attributes.
Occasionally people report problem with reboot/poweroff operations hanging in
the middle. One known cause is when a new transaction to start a unit is
enqueued while the shutdown is going on. The start of the unit conflicts with
the shutdown jobs, so they get cancelled. The failure case can be quite unpleasant,
becase getty and sshd may already be stopped.
Fix it by using irreversible jobs for shutdown (reboot/poweroff/...) actions.
This applies to commands like "reboot", "telinit 6", "systemctl reboot". Should
someone desire to use reversible jobs, they can say "systemctl start reboot.target".`
Add a new job mode: replace-irreversibly. Jobs enqueued using this mode
cannot be implicitly canceled by later enqueued conflicting jobs.
They can however still be canceled with an explicit "systemctl cancel"
call.
"systemctl default" should behave identically to "telinit N" (where N is the
corresponding runlevel target number), therefore it should use isolate job mode
too.
This makes 'status' behave like 'list-units':
systemctl status -> status of all units
systemctl -t error status -> status of error units
systemctl -t mount status -> etc.
systemctl list-dependencies lists all unit's dependecies and
recursively expands all subsidiary target units into a tree.
Primary purpose for this command is to show all units which are
enabled in specified target.
New file output.h with output flags and modes.
--full parameter also for cgls and loginctl.
Include 'all' parameter in flags (show_cgroup_by_path, show_cgroup,
show_cgroup_and_extra, show_cgroup_and_extra_by_spec).
get_process_cmdline with max_length == 0 will not ellipsize output.
Replace LINE_MAX with 0 in some calls of get_process_cmdline.
[zj: Default to --full when under pager for clgs.
Drop '-f' since it wasn't documented and didn't actually work.
Reindent a bit.
