2015-09-24util: Add test for parse_cpu_setFilipe Brandenburger
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.

2015-09-04util: document why parse_uid() returns ENXIOLennart Poettering
parse_uid() returns EINVAL for invalid strings, but ENXIO for the (uid_t) -1 user ids in order to distinguish these two cases. Document this.

2015-08-07util: Add shell_escapeRichard Maw
This is for shell-style \ escaping rather than quoting, which while it has the same effect in produced shell commands, is not exclusively useful for shell commands. shell_escape would be useful for producing sed commands, as you would be able to \ escape the normal special characters, plus whichever argument separator was chosen; or it could be used to escape arguments passed to the overlayfs mount command.
2015-08-07util: Allow non-separator coalescing parsing in extract_first_wordRichard Maw
If EXTRACT_DONT_COALESCE_SEPARATORS is passed, then leading separators, trailing separators and spans of multiple separators aren't skipped, and empty arguments from before, after or between separators may be extracted.
2015-08-07util: Don't interpret quotes by default in extract_first_wordRichard Maw
This adds an EXTRACT_QUOTES option to allow the previous behaviour, of not interpreting any character inside ' or " quotes as separators.
2015-08-07util: change unquote_*_word to extract_*_wordRichard Maw
It now takes a separators argument, which defaults to WHITESPACE if NULL is passed.
2015-08-07Convert unquote_*_word users to expect isempty(p) after the last entryRichard Maw
This is so that, when called in a loop, unquote_first_word can distinguish between reaching the end of a string because it has consumed all the input before the end, and consuming all the input. This is important because we later add a flag that allows char *in = ""; char *out; unquote_first_word(&in, &out, flags); To put "" in out, and set in = NULL, so the trailing empty string of the input can be consumed, and mark that the input has been consumed.

Manual merge of https://github.com/systemd/systemd/pull/751.
2015-08-05hostname-util: add relax parameter to hostname_is_validZbigniew Jędrzejewski-Szmek
Tests are modified to check behaviour with relax and without relax. New tests are added for hostname_cleanup(). Tests are moved a new file (test-hostname-util) because there's now a bunch of them. New parameter is not used anywhere, except in tests, so there should be no observable change.

2015-07-31test-util: add more testsDaniel Mack
Add tests for safe_ato[iu]16() and some more unbase32hexmem() torture.
2015-07-31tree-wide: introduce mfree()David Herrmann
Pretty trivial helper which wraps free() but returns NULL, so we can simplify this: free(foobar); foobar = NULL; to this: foobar = mfree(foobar);
2015-08-01busctl: add and use strcmp_ptr()Namhyung Kim
In member_compare_func(), it compares interface, type and name of members. But as it can contain NULL pointer, it needs to check them before calling strcmp(). So make it as a separate strcmp_ptr function (named after streq_ptr) so that it can be used by others. Also let streq_ptr() to use it in order to make the code simpler.

2015-07-14basic: util - add base32hexmem() function similar to hexmem()Tom Gundersen
This implements more of RFC4648.
2015-07-12basic: util - add base64mem() function similar to hexmem()Tom Gundersen
This implements RFC4648 for a slightly more compact representation of binary data compared to hex (6 bits per character rather than 4).
2015-07-12basic: util - fix errorhandling in unhexmem()Tom Gundersen
We were ignoring failures from unhexchar, which meant that invalid hex characters were being turned into garbage rather than the string rejected. Fix this by making unhexmem return an error code, also change the API slightly, to return the size of the returned memory, reflecting the fact that the memory is a binary blob,and not a string. For convenience, still append a trailing NULL byte to the returned memory (not included in the returned size), allowing callers to treat it as a string without doing a second copy.
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.
2015-06-17util: Introduce unquote_first_word_and_warnFilipe Brandenburger
It will try to unquot_first_word, but if it runs into escaping problems it will retry it adding UNQUOTE_CUNESCAPE_RELAX to the flags. If it succeeds on the second try, it will log a warning about it. If it fails both times, it will log an error. Add test cases to confirm it behaves as expected.
2015-06-17util: New flag UNQUOTE_UNESCAPE_RELAX for unquote_first_wordFilipe Brandenburger
The new flag UNQUOTE_UNESCAPE_RELAX preserves unrecognized escape sequences verbatim in unquote_first_word, either when it's a trailing backslash (similar to UNQUOTE_RELAX, but in this case keep the extra backslash in the output) or in the middle of a sequence string. Add unit test cases to ensure the new flag works as expected and to prevent regressions from being introduced. Tested with a follow up commit converting config_parse_exec() to start using unquote_first_word, in which case this flags makes it possible to preserve unrecognized escape sequences. Relevant bug: https://bugs.freedesktop.org/show_bug.cgi?id=90794
2015-06-15util: when creating temporary file names, allow including extra id string in itLennart Poettering
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.

2015-06-03util: fix another cunescape() regressionDaniel Mack
Fix a regression caused by 4034a06d ("util: rework word parsing and c unescaping code") which broke octal escape sequences. The reason for this breakage is that cunescape_one() expects 4 characters in an octal encoding, which is a stray left-over from the old code which operated on different variables to make the length check. While at it, add a test case to prevent the same thing from happening again.

2015-05-19hostname: Allow comments in /etc/hostnameMartin Pitt
The hostname(1) tool allows comments in /etc/hostname. Introduce a new read_hostname_config() in hostname-util which reads a hostname configuration file like /etc/hostname, strips out comments, whitespace, and cleans the hostname. Use it in hostname-setup.c and hostnamed and remove duplicated code. Update hostname manpage. Add tests. https://launchpad.net/bugs/1053048

2015-04-09util: add shell_maybe_quote() call for preparing a string for shell cmdline ↵Lennart Poettering
inclusion If necessary the passed string is enclosed in "", and all special characters escapes. This also ports over usage in bus-util.c and job.c to use this, instead of a incorrect local implementation that forgets to properly escape.
2015-04-07test-util: don't mix declarations and codeThomas Hindoe Paaboel Andersen
2015-04-07util: rework cunescape(), improve error handlingLennart Poettering
Change cunescape() to return a normal error code, so that we can distuingish OOM errors from parse errors. This also adds a flags parameter to control whether "relaxed" or normal parsing shall be done. If set no parse failures are generated, and the only reason why cunescape() can fail is OOM.
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
2015-03-26util: rework word parsing and c unescaping codeLennart Poettering
When parsing words from input files, optionally automatically unescape the passed strings, controllable via a new flags parameter. Make use of this in tmpfiles, and port everything else over, too. This improves parsing quite a bit, since we no longer have to process the same string multiple times with different calls, where an earlier call might corrupt the input for a later call.

2015-02-03util: rework strappenda(), and rename it strjoina()Lennart Poettering

2015-01-11shared/util: respect buffer boundary on incomplete escape sequencesZbigniew Jędrzejewski-Szmek
cunescape_length_with_prefix() is called with the length as an argument, so it cannot rely on the buffer being NUL terminated. Move the length check before accessing the memory. When an incomplete escape sequence was given at the end of the buffer, c_l_w_p() would read past the end of the buffer. Fix this and add a test.
