2016-04-22tree-wide: don't assume CLOCK_BOOTIME is generally availableLennart Poettering
Before we invoke now(CLOCK_BOOTTIME), let's make sure we actually have that clock, since now() will otherwise hit an assert. Specifically, let's refuse CLOCK_BOOTTIME early in sd-event if the kernel doesn't actually support it. This is a follow-up for #3037, and specifically: https://github.com/systemd/systemd/pull/3037#issuecomment-210199167
2016-02-15time-util: Rename and fix call of deserialize_timestamp_value()Benjamin Robin
The deserialize_timestamp_value() is renamed timestamp_deserialize() to be more consistent with dual_timestamp_deserialize() And add the NULL check back on realtime and monotonic
2016-02-16time-util: introduce deserialize_timestamp_value()Alexander Kuleshov
The time-util.c provides dual_timestamp_deserialize() function to convert value to usec_t and set it as value of ts->monotonic and ts->realtime. There are some places in code which do the same but only for one clockid_t (realtime or monotonic), when dual_timestamp_deserialize() sets value of both. This patch introduces the deserialize_timestamp_value() which converts a given value to usec_t and write it to a given timestamp.

Remove some old cruft

This should be handled fine now by .dir-locals.el, so need to carry that stuff in every file.

2016-02-10util-lib: make sure usec_sub() doesn't degrade USEC_INFINITYLennart Poettering

2016-02-10time-util: make timespec_load_nsec() staticAlexander Kuleshov
The timespec_load_nsec() function has no callers outside of the time-util.c, so we can make it static.
2016-02-09time-util: introduce usec_sub()Alexander Kuleshov
The dual_timestamp_from_realtime(), dual_timestamp_from_monotonic() and dual_timestamp_from_boottime_or_monotonic() shares the same code for comparison given ts with delta. Let's move it to the separate inline function to prevent code duplication.

This is a cleaned up result of running iwyu but without forward declarations on src/basic.
2015-11-10time-util: add parse_time(), which is like parse_sec() but allows ↵Lennart Poettering
specification of default time unit if none is specified This is useful if we want to parse RLIMIT_RTTIME values where the common UNIX syntax is without any units but refers to a non-second unit (µs in this case), but where we want to allow specification of units.

2015-09-16basic: nicer xsprintf and xstrftime assert messagesMichal Schmidt
It's nicer if the assertion failure message from a bad use of xsprintf actually mentions xsprintf instead of the expression the macro is implemented as. The assert_message_se macro was added in the previous commit as an internal helper, but it can also be used for customizing assertion failure messages like in this case. Example: char buf[10]; xsprintf(buf, "This is a %s message.\n", "long"); Before: Assertion '(size_t) snprintf(buf, ELEMENTSOF(buf), "This is a %s message.\n", "long") < ELEMENTSOF(buf)' failed at foo.c:6, function main(). Aborting. After: Assertion 'xsprintf: buf[] must be big enough' failed at foo.c:6, function main(). Aborting.

cgls/cgtop: a variety of modernizations
2015-08-28cgtop: major modernizationsLennart Poettering
In preparation of the unified cgroup support, let's clean up cgtop: a) rework time code to be based on "nsec_t" rather than "struct timespec" b) Introduce long option --order= for selecting ordering c) count number of processes only in the main hierarchy, don't bother with the controller hierarchies. We don't allow orthogonal hierarchies in systemd anymore, hence there's no point to check the other hierarchies. d) Deal with non-monotonic cpuacct values (see #749) e) When sorting groups, don't do prefix compare when ordering by number of tasks, since this is not accumulative for all children. f) Actually make --cpu without parameter work g) Don't output control characters when we get them as input. Fixes #749.
2015-08-26time-util: add new get_timezone() call to get local timezoneLennart Poettering
Let's move the timedated-specific code to time-util.h and make it generic.
2015-08-24machined: introduce pseudo-machine ".host" refererring to the host systemLennart Poettering
Some of the operations machined/machinectl implement are also very useful when applied to the host system (such as machinectl login, machinectl shell or machinectl status), hence introduce a pseudo-machine by the name of ".host" in machined that refers to the host system, and may be used top execute operations on the host system with. This copies the pseudo-image ".host" machined already implements for image related commands. (This commit also adds a PK privilege for opening a PTY in a container, which was previously not accessible for non-root.)
