2013-07-11systemctl: show cgroup tree if cgroup is empty but has non-empty childrenLennart Poettering
This makes sure "systemctl status user.slice" shows a nice cgroup tree of all logged in users.
2013-07-11loginctl: suppress cgroup tree output if cgroup is emptyLennart Poettering
same for machinectl
2013-07-11cgroup: simplify how instantiated units are mapped to cgroupsLennart Poettering
Previously for an instantiated unit foo@bar.service we created a cgroup foo@.service/foo@bar.service, in order to place all instances of the same template inside the same subtree. As we now implicitly add all instantiated units into one per-template slice we don't need this complexity anymore, and instance units can map directly to the cgroups of their full name.
2013-07-11cgroup: don't ever try to destroy the cgroup of the root sliceLennart Poettering
The root slice is after all the root cgroup, so don't attempt to delete it.
2013-07-11cgroup: don't move systemd into systems.slice when running as --user instanceLennart Poettering
2013-07-11core: implicitly create a per-template slice for all instantiated units by ↵Lennart Poettering
default If no explicit slice is configured for an instantiated unit, create an implicit one for all instances of the same template.

Same for machinectl.
2013-07-11shutdown: fix /proc/cmdline reading of 'quiet'Kay Sievers
2013-07-10core: uninstall cgroup agent only if we are running outside of a containerLennart Poettering
Since the cgroupfs is currently not virtualized for containers we shouldn't reset the hosts agent from the container.
2013-07-10cgroup: when uninstalling agent, actually turn it off firstLennart Poettering
2013-07-10user-sessions: rely on PID 1 to kill sessionsLennart Poettering
As we want to centralized cgroup access we should stop killing the user sessions directly from the systemd-user-sessions service. Instead, rely on PID 1 doing this by adding the right ordering dependencies to the session scope units.
2013-07-10logind: when creating the scope job fails, return this immediately to the ↵Lennart Poettering
client that wants to register the session Otherwise we'll hanging for the job to finish without any job existing. Similar, for machined.
2013-07-10logind: don't misunderstand UnitRemoved signals during reloadingLennart Poettering
When PID 1 reloads the units logind/machined will see UnitRemoved signals for all units. Instead of trusting these immediately, let's check the actual unit state before considering a unit gone, so that reloading PID 1 is not mistaken as the end of all sessions.
2013-07-10unit: when deserializing cgroup path add it back into cgroup hashmapLennart Poettering
Also, properly remove cgroup path from hashmap when freeing unit.
2013-07-10unit: save description/slice of transient units to /runLennart Poettering
This is necessary so that these properties survive a daemon reload.
2013-07-10core: send out "Reloading" signal before and after doing a full ↵Lennart Poettering
reload/reexec of PID 1 Since we'll unload all units/job during a reload, and then readd them it is really useful for clients to be aware of this phase hence sent a signal out before and after. This signal is called "Reloading" (despite the fact that it is also sent out during reexecution, which we consider a special case in this context) and has one boolean parameter which is true for the signal sent before the reload, and false for the signal after the reload. The UnitRemoved/JobRremoved and UnitNew/JobNew due to the reloading are guranteed to be between the pair of Reloading messages.
2013-07-10systemctl: suppress error message when doing "systemctl daemon-reexec"Lennart Poettering
When we issue a reexecution request via the private socket we need to expect a "Disconnected" in addition to "NoReply" when the connection is terminated.
2013-07-10systemctl: suppress error messages when checking whether a unit needs to be ↵Lennart Poettering
reloaded
2013-07-10scope: don't require an initialized PIDs set when deserializingLennart Poettering
When a scope unit is created due to deserialization rather than client request don't enforce that the PIDs set must be non-empty, since the cgroup is already populated.
2013-07-10core: while we are reloading don't suppress bus signalsLennart Poettering
While we are reloading we shouldn't suppress adding units to the bus queue when there are no subscribers, simply because we might not have deserialized the subscribers list yet. Hence, during reloading always assume we have subscribers.
2013-07-10core: serialize/deserialize bus subscribersLennart Poettering
2013-07-10cgroup: downgrade error message when we cannot remove a cgroup to debugLennart Poettering
Some units set KillMode=none to survive the initrd→rootfs transition. We cannot remove their cgroups, but that shouldn't really be considered an issue, so let's downgrade the error message.
2013-07-10udev: add builtin 'keyboard' to manage key mappingsKay Sievers
2013-07-10hwdb: allow list of lookup keys per given recordKay Sievers
This allows to specify: dmi:bvn*:bvr*:bd*:svnVENDOR:pn:Model 231*:pvr* dmi:bvn*:bvr*:bd*:svnVENDOR:pn:Series 12*:pvr* KEY_A=value KEY_B=value Instead of: dmi:bvn*:bvr*:bd*:svnVENDOR:pn:Model 231*:pvr* KEY_A=value KEY_B=value dmi:bvn*:bvr*:bd*:svnVENDOR:pn:Series 12*:pvr* KEY_A=value KEY_B=value
2013-07-09hwdb: return false if no property is foundKay Sievers
2013-07-08static-nodes: move creation of static nodes from udevd to tmpfilesTom Gundersen
As of kmod v14, it is possible to export the static node information from /lib/modules/`uname -r`/modules.devname in tmpfiles.d(5) format. Use this functionality to let systemd-tmpfilesd create the static device nodes at boot, and drop the functionality from systemd-udevd. As an effect of this we can move from systemd-udevd to systemd-tmpfiles-setup-dev: * the conditional CAP_MKNOD (replaced by checking if /sys is mounted rw) * ordering before local-fs-pre.target (see 89d09e1b5c65a2d97840f682e0932c8bb499f166)

2013-07-05systemd-python: wrap sd_notifyZbigniew Jędrzejewski-Szmek
_listen_fds() is modified to accept unset_environment arg as keyword, to match new notify().
2013-07-05tests: add tests for string lookup tablesZbigniew Jędrzejewski-Szmek
The tests check if the tables have entries for all values in the enum, and that the entries are unique.

2013-07-04cgroups-agent: remove ancient fallback code; turn connection error into warningKay Sievers
During re-execution and shutdown cgroups agents might not be able to connect to systemd's private D-Bus socket, the printed error to the console is misleding in that case, so turn it into a warning.
2013-07-04disable the cgroups release agent when shutting downKay Sievers
During shutdown, when we try to clean up all remaining processes, the kernel will fork new agents every time a cgroup runs empty. These new processes cause delays in the final SIGTERM, SIGKILL logic. Apart from that, this should also avoid that the kernel-forked binaries cause unpredictably timed access to the filesystem which we might need to unmount.
2013-07-04core/mount.c:mount_dump(): don't segfault, if mount is not mounted anymoreHarald Hoyer
Don't segfault, if m->from_proc_self_mountinfo and m->from_fragment is false. https://bugzilla.redhat.com/show_bug.cgi?id=957783#c9

2013-07-02replace tabs with spaces in various filesJason St. John
The affected files in this patch had inconsistent use of tabs vs. spaces for indentation, and this patch eliminates the stray tabs. Also, the opening brace of sigchld_hdl() in activate.c was moved so the opening braces are consistent throughout the file.
2013-07-02journald: drop (deleted) from _EXE= fieldsZbigniew Jędrzejewski-Szmek
The kernel adds those when the file is deleted, but we don't really care if the file is still there or not. The downside is that if the filename ends in ' (deleted)', this part of the filename will be removed. Too bad.
2013-07-02man: improve grammar and word formatting in numerous man pagesJason St. John
Use proper grammar, word usage, adjective hyphenation, commas, capitalization, spelling, etc. To improve readability, some run-on sentences or sentence fragments were revised. [zj: remove the space from 'file name', 'host name', and 'time zone'.]

2013-07-02core: make GC more aggressiveLennart Poettering
Since we should allow registering/unregistering transient units with the same name in a tight-loop, we need to make the GC more aggressive, so that dead units are cleaned up immediately instead of later. hence, execute the GC sweep on every event loop iteration and clean up units. This of course, means we need to be careful with adding units to the GC queue, which we already are since we execute check_gc() of each unit type already when adding something to the queue.
