2016-04-29test-copy: never call alloca() in a loopLennart Poettering
That's a total no-no, hence rework this to use malloc()-based memory instead of alloca()-based memory. Also see CODING_STYLE about this.
2016-04-29copy: also copy AF_UNIX socketsLennart Poettering
We previously would fail with EOPNOTSUPP when encountering an AF_UNIX socket in the directory tree to copy. Fix that, and copy them too (even if they are dead in the result). Fixes: #2914
2016-03-21test-copy: use correct data type for max_bytesMartin Pitt
copy_bytes() and the comparisons in test_copy_bytes_regular_file() expect an uint64_t, not a size_t. On 32 bit architectures the latter is 32 bit, leading to truncation errors. Fixes regression from commit 7a827fcb.

2016-03-15test-copy: add a test shuffling bytes between normal filesZbigniew Jędrzejewski-Szmek
I started looking into adding copy_file_range support, and discovered that we can improve the way we call sendfile: - sendfile(2) man page is missing an important bit: the number of bytes to copy cannot be too big (SSIZE_MAX actually), and the description of EINVAL return code does not mention this either, - our implementation works but calls sendfile over and over with a small size, which seems suboptimal. First add a test which (under strace) can be used to see current behaviour.
2015-10-27util-lib: split out allocation calls into alloc-util.[ch]Lennart Poettering
2015-10-27util-lib: move a number of fs operations into fs-util.[ch]Lennart Poettering
2015-10-25util-lib: split out fd-related operations into fd-util.[ch]Lennart Poettering
There are more than enough to deserve their own .c file, hence move them over.
2015-10-24util-lib: split our string related calls from util.[ch] into its own file ↵Lennart Poettering
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.
2015-09-10tree-wide: never use the off_t unless glibc makes us use itLennart Poettering
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.
2015-07-06fileio: consolidate write_string_file*()Daniel Mack
Merge write_string_file(), write_string_file_no_create() and write_string_file_atomic() into write_string_file() and provide a flags mask that allows combinations of atomic writing, newline appending and automatic file creation. Change all users accordingly.

2015-04-06util: rework rm_rf() logicLennart Poettering
- Move to its own file rm-rf.c - Change parameters into a single flags parameter - Remove "honour sticky" logic, it's unused these days
2015-02-03util: rework strappenda(), and rename it strjoina()Lennart Poettering
After all it is now much more like strjoin() than strappend(). At the same time, add support for NULL sentinels, even if they are normally not necessary.
