2016-04-25core: fix description of "resources" service error (#3119)Lennart Poettering
The "resources" error is really just the generic error we return when we hit some kind of error and we have no more appropriate error for the case to return, for example because of some OS error. Hence, reword the explanation and don't claim any relation to resource limits. Admittedly, the "resources" service error is a bit of a misnomer, but I figure it's kind of API now. Fixes: #2716
2016-04-22shared: move unit-specific code from bus-util.h to bus-unit-util.hLennart Poettering
Previously we'd have generally useful sd-bus utilities in bust-util.h, intermixed with code that is specifically for writing clients for PID 1, wrapping job and unit handling. Let's split the latter out and move it into bus-unit-util.c, to make the sources a bit short and easier to grok.
2016-04-22core,systemctl: add bus API to retrieve processes of a unitLennart Poettering
This adds a new GetProcesses() bus call to the Unit object which returns an array consisting of all PIDs, their process names, as well as their full cgroup paths. This is then used by "systemctl status" to show the per-unit process tree. This has the benefit that the client-side no longer needs to access the cgroupfs directly to show the process tree of a unit. Instead, it now uses this new API, which means it also works if -H or -M are used correctly, as the information from the specific host is used, and not the one from the local system. Fixes: #2945
