Since glibc is moving away from implicitly including sys/sysmacros.h
all the time via sys/types.h, include the header directly in more
places. This seems to cover most makedev/major/minor usage.
Throughout the tree there's spurious use of spaces separating ++ and --
operators from their respective operands. Make ++ and -- operator
consistent with the majority of existing uses; discard the spaces.
Usually, we place the #pragma once before the copyright blurb in header files,
but in a few cases we didn't. Move those around, so that we do the same thing
everywhere.
GLIB has recently started to officially support the gcc cleanup
attribute in its public API, hence let's do the same for our APIs.
With this patch we'll define an xyz_unrefp() call for each public
xyz_unref() call, to make it easy to use inside a
__attribute__((cleanup())) expression. Then, all code is ported over to
make use of this.
The new calls are also documented in the man pages, with examples how to
use them (well, I only added docs where the _unref() call itself already
had docs, and the examples, only cover sd_bus_unrefp() and
sd_event_unrefp()).
This also renames sd_lldp_free() to sd_lldp_unref(), since that's how we
tend to call our destructors these days.
Note that this defines no public macro that wraps gcc's attribute and
makes it easier to use. While I think it's our duty in the library to
make our stuff easy to use, I figure it's not our duty to make gcc's own
features easy to use on its own. Most likely, client code which wants to
make use of this should define its own:
#define _cleanup_(function) __attribute__((cleanup(function)))
Or similar, to make the gcc feature easier to use.
Making this logic public has the benefit that we can remove three header
files whose only purpose was to define these functions internally.
See #2008.
There are more than enough calls doing string manipulations to deserve
its own files, hence do something about it.
This patch also sorts the #include blocks of all files that needed to be
updated, according to the sorting suggestions from CODING_STYLE. Since
pretty much every file needs our string manipulation functions this
effectively means that most files have sorted #include blocks now.
Also touches a few unrelated include files.
This allows a fd to be created and configured as part of one monitor, to be passed in
to create a second monitor without having to redo any of the configuration.
This reverts b67f944. Lazy loading of device properties does not work for devices
that are received over netlink, as these are sealed. Reinstate the unconditional
loading of the device db.
Reported by: Mantas Mikulėnas <grawity@gmail.com>.
It is still possible to include uninitialized ones, but now that is opt-in. In most
cases people only want initialized devices. Exception is if you want to work without
udev running.
Suggested by David Herrmann.
Udev debug messages have to be significantly overhauled... For now
just downgrade those two. They are responsible for approximately 25%
of debug output during boot and are rather useless.
We were explicitly eagerly loading the db, then deletenig the backing file and then processing the
rules/symlinks. Instead we delete the backnig db file as the last step and let the db loading be
lazy as everywhere else.
This may save us a bit of work in casese where the db is not needed, but more importantly it hides
some implementation details of libudev-device form udevd.
Properties should only be saved to the db when added to the udev_device by udevd, and only if
the property does not start with a '.'. Make this implicit rather than expose the marking of
properties.
This patch removes includes that are not used. The removals were found with
include-what-you-use which checks if any of the symbols from a header is
in use.
