fd_get_path() is an ugly API, as it creates ambiguities related to the
" (deleted)" suffix /proc/$PID/fd/$FD shows. Let's use it a bit less
excessively, and whenever we have a good valid path already, let's
simply pass that along, instead of forgetting it in one stackframe and
reacquiring it in the next.
Even if built without gcrypt, show the relevant options in help message.
Otherwise, the help message diverges from the man page or suggestions
by the shell completion.
The "features" fields is parsed as a tristate value. The values
are thus not of type NetDevFeature enum but int. The NetDevFeature
enum is instead the index for the features array.
Adjust the type. In practice, this had no impact because NetDevFeature
enum commonly has size of int.
Also, don't use memset() 0xFF to initilize the int with -1. While
it works correctly in practice, it feels ugly.
The default setup for the Lenovo ThinkPad X140e is 104x104mm, and the kernel
claims that it's 64x21. The default 104x104mm dimensions causes the vertical
axis to act oddly, causing random vertical jitters and higher vertical
sensitivity.
Measuring it showed that it was 74x32, and these touchpad dimensions provide
a better (if a little bit slower) experience but a consistent sensitivity
in all directions.
These values were obtained using the `touchpad-edge-detector` tool.
This makes it possible to wait until boot is finished without having to poll
for this command repeatedly, instead using the syntax:
$ systemctl is-system-running --wait
Waiting is implemented by waiting for the StartupFinished signal to be posted
on the bus.
Register the matcher before checking for the property to avoid race conditions.
Tested by artificially delaying startup with a oneshot service and calling this
command, checked that it emitted `running` and exited with a 0 return code as
soon as the delay service completed startup.
Also tested that booting to degraded state unblocks the command.
Inserted a delay between getting the property and waiting for the signal and
confirmed this seems to work free of race conditions.
Updated the --help text (under --wait) and the man page to document the new
feature.
This function doesn't really implement ordering, but CMP() is still fine to use
there. Keep the comment in place, just update it slightly to indicate that.
Looked for definitions of functions using the *_compare_func() suffix.
Tested:
- Unit tests passed (ninja -C build/ test)
- Installed this build and booted with it.
Macro returns -1, 0, 1 depending on whether a < b, a == b or a > b.
It's safe to use on unsigned types.
Add tests to confirm corner cases are properly covered.
Drop __extension__, since we don't use gcc -Wpedantic or -ansi.
Reformat code for spacing. Add spaces after commas almost everywhere.
Reindent code blocks in macro definitions, for consistency.
