2016-10-11man: avoid using the term "loaded" for units currently in memory, since we ↵Lennart Poettering
also have a unit state of that name Fixes: #3971
2016-10-10core: when determining whether a process exit status is clean, consider ↵Lennart Poettering
whether it is a command or a daemon SIGTERM should be considered a clean exit code for daemons (i.e. long-running processes, as a daemon without SIGTERM handler may be shut down without issues via SIGTERM still) while it should not be considered a clean exit code for commands (i.e. short-running processes). Let's add two different clean checking modes for this, and use the right one at the appropriate places. Fixes: #4275
2016-10-10exit-status: kill is_clean_exit_lsb(), move logic to sysv-generatorLennart Poettering
Let's get rid of is_clean_exit_lsb(), let's move the logic for the special handling of the two LSB exit codes into the sysv-generator by writing out appropriate SuccessExitStatus= lines if the LSB header exists. This is not only semantically more correct, bug also fixes a bug as the code in service.c that chose between is_clean_exit_lsb() and is_clean_exit() based this check on whether a native unit files was available for the unit. However, that check was bogus since a long time, since the SysV generator was introduced and native SysV script support was removed from PID 1, as in that case a unit file always existed.

2016-09-24systemctl: suppress errors with "show" for nonexistent units and propertiesZbigniew Jędrzejewski-Szmek
Show is documented to be program-parseable, and printing the warning about about a non-existent unit, while useful for humans, broke a lot of scripts. Restore previous behaviour of returning success and printing empty or useless stuff for units which do not exist, and printing empty values for properties which do not exists. With SYSTEMD_LOG_LEVEL=debug, hints are printed, but the return value is still 0. This undoes parts of e33a06a and 3dced37b7 and fixes #3856. We might consider adding an explicit switch to fail on missing units/properties (e.g. --ensure-exists or similar), and make -P foobar equivalent to --ensure-exists --property=foobar.

2016-09-01systemctl: usable status command for special units (#4072)Cireo
Prior to this commit, users could be given an unusable command to run if they attempted to stop or start special services. For example: $ systemctl stop -- -.mount Failed to stop -.mount: Operation refused, unit -.mount may be \ requested by dependency only. See system logs and 'systemctl status -.mount' for details. $ systemctl status -.mount systemctl: invalid option -- '.' This adds a '--' to the example command in these situations.

2016-07-26systemctl: allow disable on the unit file path, but warn about it (#3806)Michal Sekletar
systemd now returns an error when it is asked to perform disable on the unit file path. In the past this was allowed, but systemd never really considered an actual content of the [Install] section of the unit file. Instead it performed disable on the unit name, i.e. purged all symlinks pointing to the given unit file (undo of implicit link action done by systemd when enable is called on the unit file path) and all symlinks that have the same basename as the given unit file. However, to notice that [Install] info of the file is not consulted one must create additional symlinks manually. I argue that in most cases users do not create such links. Let's be nice to our users and don't break existing scripts that expect disable to work with the unit file path. Fixes #3706.

Other code in systemctl assigns strings to UnitStatusInfo without copying them, relying on the fact that the message is longer lived than UnitStatusInfo. Add a helper function that is similar to map_basic, but only accepts strings and does not copy them. The alternative of continuing to use map_basic() but adding proper cleanup to free fields in UnitStatusInfo seems less attractive because it'd require changing a lot of code and doing a lot of more allocations for little gain. (I put "leaking" in quotes, because systemctl is short lived anyway.)
2016-07-25systemctl: use cleanup function for UnitStatusInfoZbigniew Jędrzejewski-Szmek
There is no functional change, but clarity of the code is increased by splitting out the cleanup part and putting it next to the structure definition.

"systemctl enable" Clarify that "systemctl enable" can operate either on unit names or on unit file paths (also, adjust the --help text to clarify this). Say that "systemctl enable" on unit file paths also links the unit into the search path. Many other fixes. This should improve the documentation to avoid further confusion around #3706.

Systemctl fixes
2016-06-16systemctl: delay pager/polkit agent opening as much as possibleZbigniew Jędrzejewski-Szmek
In https://github.com/systemd/systemd/issues/3543, we would open the pager before starting ssh, and the pipe fd was "leaked" into the ssh child as the stderr fd. Previous commit fixes bus-socket to nullify stderr before launching the child, but it seems reasonable to also delay starting the pager. If we are going to croak when trying to open the transport, it seems better to do this before starting the pager. This commit would also fix #3543 on its own.
2016-06-16systemctl: make sure we terminate the bus connection first, and then close ↵Lennart Poettering
the pager (#3550) If "systemctl -H" is used, let's make sure we first terminate the bus connection, and only then close the pager. If done in this order ssh will get an EOF on stdin (as we speak D-Bus through ssh's stdin/stdout), and then terminate. This makes sure the standard error we were invoked on is released by ssh, and only that makes sure we don't deadlock on the pager which waits for all clients closing its input pipe. (Similar fixes for the various other xyzctl tools that support both pagers and -H) Fixes: #3543

2016-06-13systemctl: rework "systemctl status" a bitLennart Poettering
This reworks "systemctl status" and "systemctl show" a bit. It removes the definition of the `property_info` structure, because we can simply reuse the existing UnitStatusInfo type for that. The "could not be found" message is now printed by show_one() itself (and not its caller), so that it is shown regardless by who the function is called. (This makes it necessary to pass the unit name to the function.) This also adds all properties found to a set, and then checks if any of the properties passed via "--property=" is mising in it, if so, a proper error is generated. Support for checking the PID file of a unit is removed, as this cannot be done reasonably client side (since the systemd instance we are talking to might sit on another host) Replaces: #3411 Fixes: #3425 Also see: #3504

2016-06-10systemctl: prolong timeout of "systemctl daemon-reload"Lennart Poettering
Reloading or reexecuting PID 1 means the unit generators are rerun, which are timed out at 90s. Make sure the method call asking for the reload is timed out at twice that, so that the generators have 90s and the reload operation has 90s too. This reworks the daemon_reload() call in systemctl, and makes it exclusively about reloading/reexecing. Previously it was used for other trivial method calls too, which didn't really help readability. As the code paths are now sufficiently different, split out the old code into a new function trivial_method(). This call also does a similar change as c8ad4efb277c3235d58789170af11bb3c847d655 but for the reload/reexec operation. Fixes: #3353
2016-06-10systemctl: don't suppress error code when handling legacy commandsLennart Poettering
For legacy commands such as /sbin/halt or /sbin/poweroff we support legacy fallbacks that talk via traditional SysV way with PID 1 to issue the desired operation. We do this on any kind of error if the primary method of operation fails. When this is the case we suppress any error message that is normally generated, in order to not confuse the user. When suppressing this log message, don't suppress the original error code, because there's really no reason to.
