2013-02-13util: *DO NOT* loop for EINTR handling with close_nointr()Colin Walters
See the linked references for why we should not do this.
2013-02-13util: introduce strcaseeq/strncaseeqThomas Hindoe Paaboel Andersen
2013-02-13use strneq instead of strncmpThomas Hindoe Paaboel Andersen
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()
2013-02-11util: rework load_env_file()Lennart Poettering
Inner library calls should not invoke log_oom(), that's something for main programs, not library calls. Don't read through uninitialized memory if a file ends in a continuation line. Add comments for the non-obvious bits. Don't choke on comment lines that are continuation lines. Simplify some things.
2013-02-11util: introduce FOREACH_LINE for iterating through filesLennart Poettering
2013-02-11env: considerably beef up environment cleaning logicLennart Poettering
Now, actually check if the environment variable names and values used are valid, before accepting them. With this in place are at some places more rigid than POSIX, and less rigid at others. For example, this code allows lower-case environment variables (which POSIX suggests not to use), but it will not allow non-UTF8 variable values. All in all this should be a good middle ground of what to allow and what not to allow as environment variables. (This also splits out all environment related calls into env-util.[ch])
2013-01-25Add _cleanup_pclose_ and fix mismatching pipe close opened by popen()Zbigniew Jędrzejewski-Szmek
Based-on-patch-by: Thomas Jarosch <thomas.jarosch@intra2net.com> cppcheck reported: [src/bootchart/svg.c:791]: (error) Mismatching allocation and deallocation: f

2013-01-18util: continuation support for load_env_fileMichal Vyskocil
Variable definitions can be written on more than one line - if each ends with a backslash, then is concatenated with a previous one. Only backslash and unix end of line (\n) are treated as a continuation. Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=58083 [zj: squashed two patches together; cleaned up grammar; removed comment about ignoring trailing backslash -- it is not ignored.] Document continuation support in systemd.exec
2013-01-18systemctl: add new "get-cgroup-attr" to query current cgroup attribute valueLennart Poettering
Also adds a pair of bus calls for this to the daemon.
2013-01-17systemctl add command list-dependenciesLukas Nykryn
systemctl list-dependencies lists all unit's dependecies and recursively expands all subsidiary target units into a tree. Primary purpose for this command is to show all units which are enabled in specified target.
2013-01-17util: fix bad memory accessLennart Poettering
2013-01-16systemctl,loginctl,cgls: do not ellipsize cgroup members when --full is ↵Lukas Nykryn
specified New file output.h with output flags and modes. --full parameter also for cgls and loginctl. Include 'all' parameter in flags (show_cgroup_by_path, show_cgroup, show_cgroup_and_extra, show_cgroup_and_extra_by_spec). get_process_cmdline with max_length == 0 will not ellipsize output. Replace LINE_MAX with 0 in some calls of get_process_cmdline. [zj: Default to --full when under pager for clgs. Drop '-f' since it wasn't documented and didn't actually work. Reindent a bit. ]

2012-11-23util: drop "," between week day and date when formatting timestampsLennart Poettering
The glibc default (as shown by the command line tool "date") doesn't put a comma there, and so we shouldn't either.
2012-11-19shared/utils: systemd-cgls shows 'n/a' when piping outputAnders Olofsson
-1 was used to signal failure, but the type was unsigned. https://bugs.freedesktop.org/show_bug.cgi?id=56644
2012-11-16journal, shared: fix warnings during compilation on 32 bitsZbigniew Jędrzejewski-Szmek
Some filesystem magics are too big to fit in 31 bits, and are wrapped to negative. f_type is an int on 32 bits, so it is signed, and we get a warning on comparison.
2012-11-14util: add strreplace() to replace a substring by another stringLennart Poettering
2012-11-12util: nicer tree drawingsMichal Schmidt
Draw trees more similar to pstree/findmnt/lsblk/...

2012-11-02util : fallback to plain ASCII drawing if locale is not UTF-8Michal Schmidt
When printing cgroup and sysfs hierarchies, avoid using UTF-8 box drawing characters if the locale is not UTF-8. https://bugzilla.redhat.com/show_bug.cgi?id=871153
2012-11-02util: add is_locale_utf8()Michal Schmidt
journalctl and vconsole-setup both implement utf8 locale detection. Let's have a common function for it. The next patch will add another use.
2012-10-30shared, core: do not always accept numbers in string lookupsMichal Schmidt
The behaviour of the common name##_from_string conversion is surprising. It accepts not only the strings from name##_table but also any number that falls within the range of the table. The order of items in most of our tables is an internal affair. It should not be visible to the user. I know of a case where the surprising numeric conversion leads to a crash. We will allow the direct numeric conversion only for the tables where the mapping of strings to numeric values has an external meaning. This holds for the following lookup tables: - netlink_family, ioprio_class, ip_tos, sched_policy - their numeric values are stable as they are defined by the Linux kernel interface. - log_level, log_facility_unshifted - the well-known syslog interface. We allow the user to use numeric values whose string names systemd does not know. For instance, the user may want to test a new kernel featuring a scheduling policy that did not exist when his systemd version was released. A slightly unpleasant effect of this is that the name##_to_string conversion cannot return pointers to constant strings anymore. The strings have to be allocated on demand and freed by the caller.
2012-10-30shared, libsystemd-daemon: check for empty strings in strto*l conversionsMichal Schmidt
strtol() and friends may set EINVAL if no conversion was performed, but they are not required to do so. In practice they don't. We need to check for it. https://bugzilla.redhat.com/show_bug.cgi?id=870577
2012-10-29util: improve overflow checksMichal Schmidt
commit 49371bb fixed the observed division by zero, but missed another occurrence of the same bug. It was also not the optimal fix. We can simply make the divisor a constant by swapping it with the compared value.
2012-10-29util: avoid divide by zero FPEDave Reisner
In early userspace, if kernel initialization happens extremely quickly, a call to systemd-timestamp can potentially result in division by zero. Ensure that the check in timespec_load, which only makes sense if tv_sec is greater than zero, is guarded by this condition.

Much like logind has a client in loginctl, and journald in journalctl introduce timedatectl, to change the system time (incl. RTC), timezones and related settings.
