When udevadm verify is invoked by an analyzer tool like rpminspect
to verify individual udev rules files, the summary just clutters the
output, so provide an option to turn the summary off.
The usage of PREFIX in this completion is mostly counter to the intended
usage of compsys in zsh. It is generally expected that completion code
provide the available completions and tags in that word position so that
compsys, with user configuration, can filter them to the appropriate set.
One egregious error caused by the usage of PREFIX here is the caching of
SYS_ALL_UNITS, which stored only the unit names prematurely filtered by
the completion prefix, affecting all future completions. For example,
$ systemctl cat nonsense<TAB>
might find no matching units if nonsense* has no matches, but now
$ systemctl cat <TAB>
will fail in all future completions even though every unit file
is a valid match, because the cached set has been erroneously filtered
by the last prefix.
When udevadm verify is invoked without positional arguments and loads
all rules files from the system like the udev daemon does, this option
can be used to operate on files underneath the specified root path.
This drops all mentions of gnu-efi and its manual build machinery. A
future commit will bring bootloader builds back. A new bootloader meson
option is now used to control whether to build sd-boot and its userspace
tooling.
We seem to have no tool to verify udev rule files. There is a simple
udev rules syntax checker in the tree, test/rule-syntax-check.py, but
it is too simple to detect less trivial issues not detected by udev,
e.g. redundant comparisons (#26593) or labels without references.
Such a tool would be beneficial not only for maintaining udev rules
distributed along with udev, but also and even more so for maintaining
third party udev rules that are more likely to have issues with syntax
and semantic correctness.
Implement a udev rules syntax and semantics checker in the form of
'udevadm verify [OPTIONS] FILE...' command that is based on
udev_rules_parse_file() interface and would apply further checks
on top of it in subsequent commits.
Resolves: #26606
The unlink command removes an entry from the ESP including
referenced files that are not referenced in other entries. That is
useful eg to have multiple entries that use the same kernel with
different options.
The cleanup command removes all files that are not referenced by any
entry.
This fixes a few unrelated issues:
- when ENABLE_MACHINED is false, machinectl is not installed, but _sd_machines
is still used in a few places that want to complete -M and such.
Also, bash completion calls machinectl in various places.
Make missing machinectl mean "no machines" in this case, so
that no error is generated in the callers.
- machinectl list --full would print multiple lines of output per machine,
breaking grep, issue introduced in e2268fa437.
Using --max-addresses=1 would fix the issue, but let's use
--max-addresses=0 because we now can.
- the lists used in various places were slightly different for no good reason.
- don't use a subshell if not necessary.
The code for bash still uses the same combined list of images and running
machines for various commands. The zsh code uses images for start/clone, and
running machines for the rest. Maybe something to fix in the future.
Replaces #25048.
(s) is just ugly with a vibe of DOS. In most cases just using the normal plural
form is more natural and gramatically correct.
There are some log_debug() statements left, and texts in foreign licenses or
headers. Those are not touched on purpose.
The new function DumpPatterns() can be used to limit (drastically) the size of
the data returned by PID1. Hence the optimization of serializing data into a
file descriptor should be less relevant than having the possibility to limit
the data when communicating with the service manager remotely.
NB: when passing patterns, the dump command omits the version of the manager as
well as the features and the timestamps.
getopt allows non-ambiguous abbreviations, so backwards-compat is maintained, and
people can use --kill-who (or even shorter abbreviations). English is flexible,
so in common speach people would use both forms, even if "whom" is technically
more correct. The advantage of using the longer form in the code is that we
effectively allow both forms, so we stop punishing people who DTGCT¹, but still
allow people to use the spoken form if they prefer.
1. Do the gramatically correct thing
When using --root=/--image= the binaries to install/update will be
picked from the directory/image. Add an option to let the caller
choose.
By default (auto) the image is tried first, and if nothing is found
then the host. The other options allow to strictly try the image
or host and ignore the other.
GIT_VERSION is not available as a config.h variable, because it's rendered
into version.h during builds. Let's rework jinja2 rendering to also
parse version.h. No functional change, the new variable is so far unused.
I guess this will make partial rebuilds a bit slower, but it's useful
to be able to use the full version string.
systemd-udev-trigger.service by default triggeres all devices regardless
of whether they were already recognized by systemd-udevd.
There are machines (especially in embedded environments) where
systemd-udev-trigger.service is configured to run at a later stage of
the boot sequence, which can lead to quite a lot of devices being
triggered although they were already recognized by systemd-udevd.
Re-triggering a lot of devices is a relatively expensive operation and
therefore should be avoided if unnecessary.
Therefore this patch introduces --initialized-nomatch, which filters out
devices that are already present in the udev database. For consistance
reasons --initialized-match is implemented as well, which filters out devices
that are *not* already present in the udev database.
Replaces #19949.
