basic: include only what we use This is a cleaned up result of running iwyu but without forward declarations on src/basic. 2015-11-30 21:43:37 +01:00			`#include <string.h>`

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. 2015-10-24 22:58:24 +02:00			`#include "login-util.h"`

core: rework cgroup path parse logic Various cleanups, be stricter when parsing unit paths. Most importantly: return the root slice "-.slice" when asked for slice of paths that contain no slice component. 2015-04-30 00:47:41 +02:00			`if (isempty(id))`
