2014-08-03Unify parse_argv styleZbigniew Jędrzejewski-Szmek
getopt is usually good at printing out a nice error message when commandline options are invalid. It distinguishes between an unknown option and a known option with a missing arg. It is better to let it do its job and not use opterr=0 unless we actually want to suppress messages. So remove opterr=0 in the few places where it wasn't really useful. When an error in options is encountered, we should not print a lengthy help() and overwhelm the user, when we know precisely what is wrong with the commandline. In addition, since help() prints to stdout, it should not be used except when requested with -h or --help. Also, simplify things here and there.
2014-04-16sysctl: replaces some slashes with dotsZbigniew Jędrzejewski-Szmek
It turns out that plain sysctl understands a.b/c syntax to write to /proc/sys/a/b.c. Support this for compatibility. https://bugs.freedesktop.org/show_bug.cgi?id=77466
2014-03-16Use strlen even for constant stringsJosh Triplett
GCC optimizes strlen("string constant") to a constant, even with -O0. Thus, replace patterns like sizeof("string constant")-1 with strlen("string constant") where possible, for clarity. In particular, for expressions intended to add up the lengths of components going into a string, this often makes it clearer that the expression counts the trailing '\0' exactly once, by putting the +1 for the '\0' at the end of the expression, rather than hidden in a sizeof in the middle of the expression.
2014-03-14shared: add root argument to search_and_fopenMichael Marineau
This adds the same root argument to search_and_fopen that conf_files_list already has. Tools that use those two functions as a pair can now be easily modified to load configuration files from an alternate root filesystem tree.
2014-01-05Remove unused variablesZbigniew Jędrzejewski-Szmek
2014-01-05strv: multiple cleanupsSimon Peeters
- turn strv_merge into strv_extend_strv. appending strv b to the end of strv a instead of creating a new strv - strv_append: remove in favor of strv_extend and strv_push. - strv_remove: write slightly more elegant - strv_remove_prefix: remove unused function - strv_overlap: use strv_contains - strv_printf: STRV_FOREACH handles NULL correctly
2013-12-24log: log_error() and friends add a newline after each line anyway, so avoid ↵Lennart Poettering
including it in the log strings
2013-11-18Remove duplicate includesKarel Zak
2013-11-06clients: unify how we invoke getopt_long()Lennart Poettering
Among other things this makes sure we always expose a --version command and show it in the help texts.
2013-08-15sysctl: allow overwriting of values specified in "later" filesKay Sievers
2013-04-13fileio: in envfiles, do not skip lines following empty linesZbigniew Jędrzejewski-Szmek

2013-04-03util: rename write_one_line_file() to write_string_file()Lennart Poettering
You can write much more than just one line with this call (and we frequently do), so let's correct the naming.
2013-03-27systemd-sysctl: Handle missing /etc/sysctl.conf properlyEelco Dolstra
Since fabe5c0e5fce730aa66e10a9c4f9fdd443d7aeda, systemd-sysctl returns a non-zero exit code if /etc/sysctl.conf does not exist, due to a broken ENOENT check.
2013-02-14honor SELinux labels, when creating and writing config filesHarald Hoyer
Also split out some fileio functions to fileio.c and provide a SELinux aware pendant in fileio-label.c see https://bugzilla.redhat.com/show_bug.cgi?id=881577
2013-02-13sysctl: fix uninitalized memory access in error pathZbigniew Jędrzejewski-Szmek
src/sysctl/sysctl.c: In function ‘parse_file’: src/sysctl/sysctl.c:172:41: warning: ‘property’ may be used uninitialized in this function [-Wmaybe-uninitialized]
2013-02-11binfmt,tmpfiles,modules-load,sysctl: rework the various early-boot services ↵Lennart Poettering
that work on .d/ directories This unifies much of the logic behind them: - All four will now ofllow the rule that the earlier file and earlier assignment in the .d/ directories wins. Before, sysctl was the only outlier, where the later setting always won. - All four now support getopt() and --help on the command line. - All four can now handle specification of configuration file names on the command line to apply. The tools will automatically find them, and apply them. Previously only tmpfiles could do that. This is useful for %post scripts in RPMs and suchlike. - This fixes various error path issues in conf_files_list()

2012-10-06sysctl: avoiding exiting with error on -EEXISTDave Reisner
If the final key in any sysctl.d file is a duplicate, systemd-sysctl will exit with an error (and no explaination why). Ignore this, as duplicate keys are to be expected when overriding settings in the directory hierarchy.
2012-09-21sysctl: always return the last error we encounteredLennart Poettering
2012-09-21sysctl: fix error code handlingLukas Nykryn
After if (r <= 0) r can't be 0 so if (k < 0 && r == 0) never happens.
2012-08-06sysctl: apply configuration at onceMichal Sekletar
https://bugzilla.redhat.com/show_bug.cgi?id=767795 [ Simplified by iterating the config files in the backwards order - no need for hashmap_update(). Other minor cleanups. -- michich ]
2012-07-26log.h: new log_oom() -> int -ENOMEM, use itShawn Landden
also a number of minor fixups and bug fixes: spelling, oom errors that didn't print errors, not properly forwarding error codes, few more consistency issues, et cetera
2012-07-25use "Out of memory." consistantly (or with "\n")Shawn Landden
glibc/glib both use "out of memory" consistantly so maybe we should consider that instead of this. Eliminates one string out of a number of binaries. Also fixes extra newline in udev/scsi_id
