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.
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.
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
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.
Hiding the first column, which may contain bullet circles, with --no-legend
is undocumented and potentially unexpected. On the other hand, not printing
bullet circles with --plain is documented so hiding the column with that
switch is sensible.
The combination "--full --no-legend --no-pager --plain" is appropriate for
automated processing of systemctl output.
The AA is unnecessary and only adds needless complexity. Replace it
with a case statement instead of repeatedly calling __contains_word to
overglorify string equalities.
- scope the iterator var
- use the correct, quoted, non-expansion prone positional parameter
notation
- prevent expansion on RHS of comparison
- remove unneeded explicit returns.
This really should be defined only once...
Split the large bash completion script into separate, smaller files each
named after the binary it is used for and move the files to
/usr/share/bash-completion/completions. This way the completions can be
loaded on demand and we only install the completions for the tools we
actually build. The old path /etc/bash_completion.d/ is deprecated and
will disappear in the future.
