tree-wide: expose "p"-suffix unref calls in public APIs to make gcc cleanup easy 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.
util-lib: split out allocation calls into alloc-util.[ch]
util-lib: move a number of fs operations into fs-util.[ch]
util-lib: move more file I/O related calls into fileio.[ch]
util-lib: split out fd-related operations into fd-util.[ch] There are more than enough to deserve their own .c file, hence move them over.
util-lib: split our string related calls from util.[ch] into its own file string-util.[ch] 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.
util: introduce common version() implementation and use it everywhere This also allows us to drop build.h from a ton of files, hence do so. Since we touched the #includes of those files, let's order them properly according to CODING_STYLE.
Revert "hwdb: actually search /run/udev/hwdb.d"
hwdb: actually search /run/udev/hwdb.d The documentation claims hwdb entries may be placed in the volatile /run/udev/hwdb.d directory but nothing actually looked at it.
remove unused includes 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.
hwdb: adjust --help text to be more like other --help texts Fix capitalization, indentation, make sure we support --version, and similar.
Assorted format fixes Types used for pids and uids in various interfaces are unpredictable. Too bad.
systemd-hwdb: port to new verbs helper
systemd-hwdb: introduce new tool This pulls out the hwdb managment from udevadm into an independent tool. The old code is left in place for backwards compatibility, and easy of testing, but all documentation is dropped to encourage use of the new tool instead.
