Whenever a unit deactivates sucessfully we so far generated a message
"unit xyz: succeeded". This is a bit confusing, since various unit types
cannot really "succeed", e.g. a device unit can't really "suceed", not
can a swap unit. In particular in the latter case people would probably
assume that a swap unit that "suceeded" would actually mean a swap was
active now, but the opposite is actually true.
Let's improve this by saying "Deactivated successfully", which hopefully
clears this up.
(I thought about saying "terminated" or "completed" or "finished" or so
instead, but that too doesn#t make sense if you think about unit types
like swaps or devices.)
Docker doesn't set $container, so it cannot be detected that way. Instead, we
check for presence of /.dockerinit, which it creates. Podman does set
$container, but some Red Hat images (in particular, Fedora images) override
$container to equal "oci". So to correctly detect Podman containers, we check
for presence of /run/.containerenv, which is created by Podman and is now the
official way to get information about the container from within the container.

Add 'reattach' verb to portablectl, and corresponding DBUS interface
to systemd-portabled.
Takes the same parameters as 'attach', but it will do a 'detach' (and
it will refuse to proceed if it cannot be done) first, matching on
the unversioned prefix of the new image. Eg:
portablectl reattach /tmp/foo_2.raw
will cause foo_1.raw to be detached, and foo_2.raw to be attached.
The key difference with a manual 'detach old' plus 'attach new' is that
the running units are not disturbed until after the attach completed,
and if --now is passed they are then restarted.
A 'detach' is not allowed normally if the units are running.
By using a restart-after-deploy method, 'reattach' allows for minimal
interruption of service and also for features that only work on restart
(eg: file descriptor store) to work as intended.
The DBUS interface returns two lists: first the removals from the detach
that were not immediately re-added in the attach, so that the caller
can stop the relevant units, and then the list of additions that are
either new or updates, so that the caller can restart/enable the
relevant units. portablectl already implements this with the existing
--now/--enable switches.
Binaries on the latest Arch Linux use `call` instructions instead of
`callq`, which breaks the ASan detection and eventually the image
building process (due to insufficient space).
Let's drop unused function arguments, and needless double pointers where
we can.
no actual change in behaviour, just simplifications
(I tried to track down #14026 without success, and this came out of it)
The implementation is a bit ugly because we set the output variable
twice. But we were already doing this on error, so this is not
significantly worse. Doing this allows us to avoid goto's, and the
compiler should be able to figure this out and only set once.
We'd return -1 (-EPERM), even though we have a general rule to use real errno
values. The particular case that caught my attention was:
$ sudo udevadm control -l asdf
Failed to parse log priority 'asdf': Operation not permitted
... but "git grep 'r =.*_from_string' src/" return 110 hits. Confusingly, some
of the _from_string functions already return a proper errno value, so not all
of those are broken, but probably quite a few.
As suggested in https://github.com/systemd/systemd/pull/11484#issuecomment-775288617.
This does not touch anything exposed in src/systemd. Changing the defines there
would be a compatibility break.
Note that tests are broken after this commit. They will be fixed in the next one.
A hole was/is present after the booleans, so changing them to be one byte each
doesn't change the structure size (122 bits on amd64). If we add more stuff
later, it might make sense to turn some of those into bitfields again. For now,
let's take the easy route. EINVAL fits into type now.
Code size it minimally reduced:
-rwxrwxr-x 1 zbyszek zbyszek 4109792 Feb 10 14:00 build/libsystemd.so.0.30.0
-rwxrwxr-x 1 zbyszek zbyszek 4109712 Feb 10 14:01 build/libsystemd.so.0.30.0
By rearranging the fields, we can avoid one of the holes (on amd64).
By adding more space for .type, -EINVAL can be used as a value later on.
The structure is reduced from 96 to 88 bytes (on amd64).
Text size is also smaller:
-rwxrwxr-x 1 zbyszek zbyszek 4109832 Feb 9 19:50 build/libsystemd.so.0.30.0
-rwxrwxr-x 1 zbyszek zbyszek 4109792 Feb 9 19:51 build/libsystemd.so.0.30.0
Every bitfield may make the object a little smaller, but requires additional
code when accessing the field. So it only makes sense in objects that are
created in many many copies. The Manager is pretty much a singleton.
-rwxrwxr-x 1 zbyszek zbyszek 4443840 Feb 9 16:14 build/systemd
-rwxrwxr-x 1 zbyszek zbyszek 4442552 Feb 9 16:42 build/systemd
We save 1288 bytes of code by "wasting" a few bytes on storage. (The speed
advantages are probably more important, but harder to measure…)
Doing it all in one line and with negation in front seemed like a good
idea at some point, but I think it is vastly easier to understand when
it is split out a bit.
This improves the output of the "list" and "info" verbs and adds
coredump size information to the output.
For doing that a common helper function is added that analyzes the
coredump file on disk.
Let's use our table formatter for generating the coredump table. Bring
support up to our current standards, with a bit of color, JSON output
and so on.
Also adds supports for setting a max for the number of lines to
generate. (with the new -n switch)
The existing -1 switch now becomes a synonym for "-n 1 --reverse"
Fixes: #3271
This way we can display invalid UIDs/GIDs/PIDs as n/a while still
storing them as is.
Also, let's add a new cell type for unix signal, that is stored as
integer, but displayed as signal name string.
Some folks argue that NOTIMP should only be returned if a specific QTYPE
is not supported. While I don#t think the RFCs are too clear about that,
let's use REFUSED instead, which appears to be a less controversial
choice of error code.
