Negative switches are a bad un-normalized thing. We alerady have some,
but we should try harder to avoid intrdoucing new ones.
Hence, instead of adding two switches:
--foobar
--no-foobar
Let's instead use the syntax
--foobar
--foobar=yes
--foobar=no
Where the first two are equivalent. The boolean argument is parsed
following the usual rules.
Change all new negative switches this way.
This patch also properly aligns the --help table, so that single char
switches always get a column separate of the long switches.
Since b5eca3a205 we don't attempt to GC
busses anymore when unsent messages remain that keep their reference,
when they otherwise are not referenced anymore. This means that if we
explicitly want connections to go away, we need to close them.
With this change we will no do so explicitly wherver we connect to the
bus from a main program (and thus know when the bus connection should go
away), or when we create a private bus connection, that really should go
away after our use.
This fixes connection leaks in the NSS and PAM modules.
getopt is usually good at printing out a nice error message when
commandline options are invalid. It distinguishes between an unknown
option and a known option with a missing arg. It is better to let it
do its job and not use opterr=0 unless we actually want to suppress
messages. So remove opterr=0 in the few places where it wasn't really
useful.
When an error in options is encountered, we should not print a lengthy
help() and overwhelm the user, when we know precisely what is wrong
with the commandline. In addition, since help() prints to stdout, it
should not be used except when requested with -h or --help.
Also, simplify things here and there.
Both systemd-analyze and systemd-run only access org.freedesktop.systemd1
on the bus. This patch allows using systemd-run --user and systemd-analyze
--user even if the user session's bus is not properly integrated with the
systemd user unit.

systemd-analyze plot > test.svg produces output with all y and height
element attributes equal to zero. This of course causes the resulting
svg to appear blank (zero height). Bug does not affect x86. Looks like
a compiler optimization may be the culprit.

Let's unify generation of unicode chars at one place.
Also, don't add an extra space into chars we print, except for the tree
chars where this is really necessary.
- Add space between if/for and the opening parentheses
- Place the opening brace on same line as the function (not for udev)
From the CODING_STYLE
Try to use this:
void foo() {
}
instead of this:
void foo()
{
}
The sd-event APIs should be available only as part of libsystemd-bus so
that the utility calls are not linked into each independently and we can
minimize the number of libraries we have.
Set the width of the svg to always fit the longest string
while taking its starting position into consideration.
Place the text on the right while the starting point is
in the first half of the screen. After that we put it on
the left to save the svg from being wider that it has to.
Since the invention of read-only memory, write-only memory has been
considered deprecated. Where appropriate, either make use of the
value, or avoid writing it, to make it clear that it is not used.
This extends 62678ded 'efi: never call qsort on potentially
NULL arrays' to all other places where qsort is used and it
is not obvious that the count is non-zero.
"systemctl set-log-level" is a command for analysis and tracing hence
"systemd-analyze" should be the better home for it, thus allowing us to
make the overly large "systemctl" a bit smaller.
It's an analysis command and its format is explicitly not covered by any
stability guarantees, hence move away from systemctl and into
systemd-analyze, minimizing the already large interface of systemctl a
bit.
This patch also adds auto-paging to the various systemd-analyze commands
where that makes sense
This will add another color to the legend called "Loading unit files"
Like the generators it will mark a part of the systemd bar indicating
the time spent while loading unit files.
Make "systemd-analyze dot" output only lines with units matching
given glob(7) patterns. Add --from-pattern and --to-pattern options.
Without any patterns all relationships are printed as before.
A relationship must match the follwing expression:
(isempty(from) || from[0] || from[1] || .. || from[n]) &&
(isempty(to) || to[0] || to[1] || .. || to[n]) &&
(isempty(P) || P[0] || P[1] || ... || P[n])
where from[] and to[] are lists of patterns provided with subsequent
--from-pattern and --to-pattern respectively. P[] is a list of additional
patterns provided after the "dot" subcommand.
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.
