2012-05-04readahead: store inode numbers in pack fileLennart Poettering
If the inode nr for each file is available in the pack file we can easily detect replaced files (like they result from package upgrades) which we can then skip to readahead.
2012-05-04units: use OOMScoreAdjust= in the unit files to set OOM score adjustLennart Poettering
2012-05-04readhead: temporarily lower the kernel's read_ahead_kb setting while collectingLennart Poettering
While collecting readahead data we want to know exactly what userspace accesses unblurred by the kernel's read_ahead_kb. Hence lower this during collection, and raise it afterwards. This is mostly based on ideas and code by Auke Kok.

2012-05-03dbus: include unit name in JobNew/JobRemoved signalsLennart Poettering
This breaks D-Bus interface slightly, but since the D-Bus API isn't covered by the interface stability promise this should be OK.
2012-05-03service: explicitly remove control/ subcgroup after each control commandLennart Poettering
The kernel will only notify us of cgroups running empty if no subcgroups exist anymore. Hence make sure we don't leave our own control/ subcgroup around longer than necessary. https://bugzilla.redhat.com/show_bug.cgi?id=818381

2012-04-30unit: add new dependency type RequiresMountsFor=Lennart Poettering
RequiresMountsFor= is a shortcut for adding requires and after dependencies to all mount units neeed for the specified paths. This solves a couple of issues regarding dep loop cycles for encrypted swap.

2012-04-29udev: use container_of() macroLucas De Marchi
2012-04-29util: introduce container_of() macroLucas De Marchi
This macro comes from kernel and it's useful for unwrapping structs inside another one. The generated code is actually the same to the one where this logic is used in udev, but using this macro is much cleaner and less error prone.

2012-04-25core: add NOP jobs, job type collapsingMichal Schmidt
Two of our current job types are special: JOB_TRY_RESTART, JOB_RELOAD_OR_START. They differ from other job types by being sensitive to the unit active state. They perform some action when the unit is active and some other action otherwise. This raises a question: when exactly should the unit state be checked to make the decision? Currently the unit state is checked when the job becomes runnable. It's more sensible to check the state immediately when the job is added by the user. When the user types "systemctl try-restart foo.service", he really intends to restart the service if it's running right now. If it isn't running right now, the restart is pointless. Consider the example (from Bugzilla[1]): sleep.service takes some time to start. hello.service has After=sleep.service. Both services get started. Two jobs will appear: hello.service/start waiting sleep.service/start running Then someone runs "systemctl try-restart hello.service". Currently the try-restart operation will block and wait for sleep.service/start to complete. The correct result is to complete the try-restart operation immediately with success, because hello.service is not running. The two original jobs must not be disturbed by this. To fix this we introduce two new concepts: - a new job type: JOB_NOP A JOB_NOP job does not do anything to the unit. It does not pull in any dependencies. It is always immediately runnable. When installed to a unit, it sits in a special slot (u->nop_job) where it never conflicts with the installed job (u->job) of a different type. It never merges with jobs of other types, but it can merge into an already installed JOB_NOP job. - "collapsing" of job types When a job of one of the two special types is added, the state of the unit is checked immediately and the job type changes: JOB_TRY_RESTART -> JOB_RESTART or JOB_NOP JOB_RELOAD_OR_START -> JOB_RELOAD or JOB_START Should a job type JOB_RELOAD_OR_START appear later during job merging, it collapses immediately afterwards. Collapsing actually makes some things simpler, because there are now fewer job types that are allowed in the transaction. [1] Fixes: https://bugzilla.redhat.com/show_bug.cgi?id=753586
2012-04-25timedated: introduce systemd-timedated-ntp.target which is controlled by ↵Lennart Poettering
timedated's NTP setting We shouldn't hardcode the name of the NTP implementation in the timedated mechanism, especially since Fedora currently switched from NTP to chrony. This patch introduces a new target that is enabled/disabled instead of the actual NTP implementation. The various NTP implementations should then add .wants/ symlinks to their services and BindTo back to the target, so that their implementations are started/stopped jointly with the target. https://bugzilla.redhat.com/show_bug.cgi?id=815748

2012-04-24remount: consolidate remount-api-vfs and remount-rootfs into oneLennart Poettering
This has the advantage of removing a confusing warning by mount if the root directory is not listed in fstab.

2012-04-24service: introduce Type=idle and use it for gettysLennart Poettering
Type=idle is much like Type=simple, however between the fork() and the exec() in the child we wait until PID 1 informs us that no jobs are left. This is mostly a cosmetic fix to make gettys appear only after all boot output is finished and complete. Note that this does not impact the normal job logic as we do not delay the completion of any jobs. We just delay the invocation of the actual binary, and only for services that otherwise would be of Type=simple.
2012-04-24manager: drop MountAuto= and SwapAuto= optionsLennart Poettering
The ability to set MountAuto=no and SwapAuto=no was useful during the adoption phase of systemd, so that distributions could stick to their classic mount scripts a bit longer. It is about time to get rid of it now.

2012-04-23transaction: cancel jobs non-recursively on isolateMichal Schmidt
Recursive cancellation of jobs would trigger OnFailure actions of dependent jobs. This is not desirable when isolating. Fixes https://bugzilla.redhat.com/show_bug.cgi?id=798328
2012-04-24job: serialize jobs properlyMichal Schmidt
Jobs were not preserved correctly over a daemon-reload operation. A systemctl process waiting for a job completion received a job removal signal. The job itself changed its id. The job timeout started ticking all over again. This fixes the deficiencies.
2012-04-24transaction: abort does not need to use recursive deletionMichal Schmidt
Recursion is unnecessary, because we're deleting all transaction jobs anyway. And the recursive deletion produces debug messages that are pointless in transaction abort.
2012-04-24transaction: fix detection of cycles involving installed jobsMichal Schmidt
A transaction can be acyclic, but when it's added to installed jobs, a cycle may result. transaction_verify_order_one() attempts to detect these cases, but it fails because the installed jobs often have the exact generation number that makes them look as if they were walked already. Fix it by resetting the generation numbers of all installed jobs before detecting cycles. An alternative fix could be to add the generation counter to the Manager and use it instead of starting always from 1 in transaction_activate(). But I prefer not having to worry about it wrapping around.
2012-04-24transaction: improve readabilityMichal Schmidt
The functions looked complicated with the nested loops with breaks, continues, and "while (again)". Here using goto actually makes them easier to understand. Also correcting the comment about redundant jobs.
