Before, we would initialize many fields twice: first
by filling the structure with zeros, and then a second
time with the real values. We can let the compiler do
the job for us, avoiding one copy.
A downside of this patch is that text gets slightly
bigger. This is because all zero() calls are effectively
inlined:
$ size build/.libs/systemd
text data bss dec hex filename
before 897737 107300 2560 1007597 f5fed build/.libs/systemd
after 897873 107300 2560 1007733 f6075 build/.libs/systemd
… actually less than 1‰.
A few asserts that the parameter is not null had to be removed. I
don't think this changes much, because first, it is quite unlikely
for the assert to fail, and second, an immediate SEGV is almost as
good as an assert.

A fix for ff03aed06a422.

For some reason this shows up on i686 only:
src/udev/udev-builtin-usb_id.c:192:20: warning: comparison between signed and unsigned integer expressions [-Wsign-compare]

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:

This should allow system services to take over key handling for all
sessions, globally.

It is possible to build systemd without logind or run logind without systemd
init. Commit 66e41181 fixed sd_booted() to only succeed for systemd init; with
that, testing for systemd init is wrong in the parts that talk to logind.
In particular, this affects the PAM module and the "uaccess" udev builtin.
Change sd_booted() to a new logind_running() which tests for
/run/systemd/seats/.

Skipping the parsing of /etc/vconsole.conf just because some values were
already assigned from the cmdline never made sense. And by the way, commit
f73141d changed the return values of parse_env_file() - it now gives 0
on success. Which means in current HEAD /etc/vconsole.conf overrides the
cmdline, which is the reverse of what's expected.
We need to parse /etc/vconsole.conf first and then let vconsole.*
overrides from cmdline take effect. The behaviour is documented in
vconsole.conf(5).

That way we can allocate an error struct on-the-fly while calling a
function. Nice!

We don't need this right now, but we should keep our options open, in
case we need more than just an fd for waking up.

The password query for a crypto device currently times out after 90s,
which is too short to grab a cup of coffee when a machine boots up.
The resulting decrypted device /dev/mapper/luks-<uuid> might not
be a mountpoint (but part of a LVM PV or raid array)
and therefore the timeout cannot be controlled by the settings
in /etc/fstab. For this reason this device should not carry its own timeout.
Also the encrypted device /dev/disk/by-*/* already has a timeout and
additionally the timeout for the password query is set in /etc/crypttab.
This patch disables the timeout of the resulting decrypted devices by creating
<device-unit>.d/50-job-timeout-sec-0.conf files with "JobTimeoutSec=0".

flags to wait for
We should keep our options open, so that we can watch for POLLOUT later
on if we wish to. CUrrently this call will always return POLLIN however.

This function should be used when filling in "struct pollfd"'s .events
field for watching the journal. It will always return POLLIN for now,
but we should keep our options open to change this later on.
This mimics libsystemd-bus' sd_bus_get_events() call with the same
purpose.

Make sure to always print out at least one valid component instead of

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.
|
|
We can now parse "0.5s" as the same as "500ms". In fact, we can parse
"3.45years" correctly, too, and any other unit and fraction length.

internet hostname unset the pretty name
If people are unaware or uninterested in the concept of pretty host
names, and simply invoke "hostnamectl set-hostname" for a valid internet
host name, then use this as indication to unset the pretty host name and
only set the static/dynamic one.
This also allows fqdn, hence "hostnamectl set-hostname www.foobar.com"
will just work if people really insist on using fqdns as hostnames.
|

This will properly escape all weird chars when writing env var files.
With this in place we can now read and write environment files where the
values contain arbitrary weird chars.
This enables hostnamed and suchlike to finally properly save pretty host
names with backlashes or quotes in them.
|
|
Implement this with a proper state machine, so that newlines and
escaped chars can appear in string assignments. This should bring the
parser much closer to shell.
|
|
Internally we store all time values in usec_t, however parse_usec()
actually was used mostly to parse values in seconds (unless explicit
units were specified to define a different unit). Hence, be clear about
this and name the function about what we pass into it, not what we get
out of it.
|
|
You can write much more than just one line with this call (and we
frequently do), so let's correct the naming.

mss-myhostname wasn't working because of underlinking. Instead of
fixing the underlinking, just remove the use of _cleanup_ macros.
It is impolite to use our utility functions in modules designed to be
loaded by others. So cleanup macros which (at some point) call assert
which calls log_assert_failed, should not be used. Revert this part of
commit d73c3269c.
