tree-wide: remove Emacs lines from all files This should be handled fine now by .dir-locals.el, so need to carry that stuff in every file.

basic: re-sort includes My previous patch to only include what we use accidentially placed the added inlcudes in non-sorted order.

basic: include only what we use This is a cleaned up result of running iwyu but without forward declarations on src/basic.

util-lib: split out allocation calls into alloc-util.[ch]

util-lib: split out umask-related code to umask-util.h

util-lib: move a number of fs operations into fs-util.[ch]

util-lib: split out file attribute calls to chattr-util.[ch]

util-lib: split xattr-related calls into xattr-util.[ch]

util-lib: introduce dirent-util.[ch] for directory entry calls Also, move a couple of more path-related functions to path-util.c.

util-lib: move more file I/O related calls into fileio.[ch]

util-lib: split out IO related calls to io-util.[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.

copy: make copy_bytes() return whether we hit EOF or not

copy: be more careful when trying to reflink

tree-wide: never use the off_t unless glibc makes us use it off_t is a really weird type as it is usually 64bit these days (at least in sane programs), but could theoretically be 32bit. We don't support off_t as 32bit builds though, but still constantly deal with safely converting from off_t to other types and back for no point. Hence, never use the type anymore. Always use uint64_t instead. This has various benefits, including that we can expose these values directly as D-Bus properties, and also that the values parse the same in all cases.

copy: add splice() based fallback Apparently, sendfile() does not work between fifos and ttys, but splice() does, hence let's optionally fall back to that. This is useful to implement the fallback pager this way.

tree-wide: introduce mfree() Pretty trivial helper which wraps free() but returns NULL, so we can simplify this: free(foobar); foobar = NULL; to this: foobar = mfree(foobar);

copy: when we recursively copy a directory tree, copy everything Don't ignore hidden files and directories. Fixes #386

util: when creating temporary file names, allow including extra id string in it This adds a "char *extra" parameter to tempfn_xxxxxx(), tempfn_random(), tempfn_ranomd_child(). If non-NULL this string is included in the middle of the newly created file name. This is useful for being able to distuingish the kind of temporary file when we see one. This also adds tests for the three call. For now, we don't make use of this at all, but port all users over.

build-sys: split internal basic/ library from shared/ basic/ can be used by everything cannot use anything outside of basic/ libsystemd/ can use basic/ cannot use shared/ shared/ can use libsystemd/
