2015-05-11core: rename SystemdRunningAs to ManagerRunningAsLennart Poettering
It's primarily just a property of the Manager object after all, and we try to refer to PID 1 as "manager" instead of "systemd", hence let's to stick to this here too.
2015-05-11unit: move unit_warn_if_dir_nonempty() and friend to unit.cLennart Poettering
The call is only used by the mount and automount unit types, but that's already enough to consider it generic unit functionality, hence move it out of mount.c and into unit.c.
2015-05-11core,network: major per-object logging reworkLennart Poettering
This changes log_unit_info() (and friends) to take a real Unit* object insted of just a unit name as parameter. The call will now prefix all logged messages with the unit name, thus allowing the unit name to be dropped from the various passed romat strings, simplifying invocations drastically, and unifying log output across messages. Also, UNIT= vs. USER_UNIT= is now derived from the Manager object attached to the Unit object, instead of getpid(). This has the benefit of correcting the field for --test runs. Also contains a couple of other logging improvements: - Drops a couple of strerror() invocations in favour of using %m. - Not only .mount units now warn if a symlinks exist for the mount point already, .automount units do that too, now. - A few invocations of log_struct() that didn't actually pass any additional structured data have been replaced by simpler invocations of log_unit_info() and friends. - For structured data a new LOG_UNIT_MESSAGE() macro has been added, that works like LOG_MESSAGE() but prefixes the message with the unit name. Similar, there's now LOG_LINK_MESSAGE() and LOG_NETDEV_MESSAGE(). - For structured data new LOG_UNIT_ID(), LOG_LINK_INTERFACE(), LOG_NETDEV_INTERFACE() macros have been added that generate the necessary per object fields. The old log_unit_struct() call has been removed in favour of these new macros used in raw log_struct() invocations. In addition to removing one more function call this allows generated structured log messages that contain two object fields, as necessary for example for network interfaces that are joined into another network interface, and whose messages shall be indexed by both. - The LOG_ERRNO() macro has been removed, in favour of log_struct_errno(). The latter has the benefit of ensuring that %m in format strings is properly resolved to the specified error number. - A number of logging messages have been converted to use log_unit_info() instead of log_info() - The client code in sysv-generator no longer #includes core code from src/core/. - log_unit_full_errno() has been removed, log_unit_full() instead takes an errno now, too. - log_unit_info(), log_link_info(), log_netdev_info() and friends, now avoid double evaluation of their parameters
2015-05-05core: rework unit name validation and manipulation logicLennart Poettering
A variety of changes: - Make sure all our calls distuingish OOM from other errors if OOM is not the only error possible. - Be much stricter when parsing escaped paths, do not accept trailing or leading escaped slashes. - Change unit validation to take a bit mask for allowing plain names, instance names or template names or an combination thereof. - Refuse manipulating invalid unit name
2015-04-30core: simplify unit type detection logicLennart Poettering
Introduce a new call unit_type_supported() and make use of it everywhere. Also, drop Manager parameter from per-type supported method prototype.

2015-04-27core: coldplug all units which participate in jobs during coldpluggingIvan Shapovalov
This is yet another attempt to fix coldplugging order (more especially, the problem which happens when one creates a job during coldplugging and it references a not-yet-coldplugged unit). Now we forcibly coldplug all units which participate in jobs. This is a superset of previously implemented handling of the UNIT_TRIGGERS dependencies, so that handling is removed. http://lists.freedesktop.org/archives/systemd-devel/2015-April/031212.html https://bugs.freedesktop.org/show_bug.cgi?id=88401 (once again)
2015-04-24core: minor simplificationLennart Poettering
2015-04-24unit: don't add automatic dependencies on device units if they aren't supportedLennart Poettering
http://lists.freedesktop.org/archives/systemd-devel/2015-April/031187.html
2015-04-24core: always coldplug units that are triggered by other units before thoseLennart Poettering
Let's make sure that we don't enqueue triggering jobs for units before those units are actually fully loaded. http://lists.freedesktop.org/archives/systemd-devel/2015-April/031176.html https://bugs.freedesktop.org/show_bug.cgi?id=88401
2015-04-24Revert "core: do not spawn jobs or touch other units during coldplugging"Lennart Poettering
This reverts commit 6e392c9c45643d106673c6643ac8bf4e65da13c1. We really shouldn't invent external state keeping hashmaps, if we can keep this state in the units themselves.
2015-04-21core: make unit deserialization more defensiveLennart Poettering
2015-04-16core: fix spurious warning about cpuacct-usage-base deserializationZbigniew Jędrzejewski-Szmek
The key was parsed properly, but the warning was still generated.
2015-04-10shared: add process-util.[ch]Ronny Chevalier
2015-04-10shared: add formats-util.hRonny Chevalier
2015-04-10core: set_put never returns -EEXISTRonny Chevalier
When the value is already there it returns 0. Also add a test to ensure this
2015-03-13tree-wide: there is no ENOTSUP on linuxDavid Herrmann
Replace ENOTSUP by EOPNOTSUPP as this is what linux actually uses.
2015-03-07core: do not spawn jobs or touch other units during coldpluggingIvan Shapovalov
Because the order of coldplugging is not defined, we can reference a not-yet-coldplugged unit and read its state while it has not yet been set to a meaningful value. This way, already active units may get started again. We fix this by deferring such actions until all units have been at least somehow coldplugged. Fixes https://bugs.freedesktop.org/show_bug.cgi?id=88401
2015-03-02core: expose consumed CPU time per unitLennart Poettering
This adds support for showing the accumulated consumed CPU time per-unit in the "systemctl status" output. The property is also readable via the bus.
2015-02-28core: rework device state logicLennart Poettering
This change introduces a new state "tentative" for device units. Device units are considered "plugged" when udev announced them, "dead" when they are not available in the kernel, and "tentative" when they are referenced in /proc/self/mountinfo or /proc/swaps but not (yet) announced via udev. This should fix a race when device nodes (like loop devices) are created and immediately mounted. Previously, systemd might end up seeing the mount unit before the device, and would thus pull down the mount because its BindTo dependency on the device would not be fulfilled.
2015-02-26core: emit changes for NFailedUnits propertyLucas De Marchi
By notifying the clients when this property is changed it's possible to allow "system health monitor" tools to get transitions like running<->degraded. This is an alternative to send changes on the SystemState property since the latter is more difficult to derive.
2015-02-26unit: When stopping due to BindsTo=, log which unit caused itColin Walters
I'm trying to track down a relatively recent change in systemd which broke OSTree; see https://bugzilla.gnome.org/show_bug.cgi?id=743891 Systemd started to stop sysroot.mount, and this patch should help me debug why at least. While we're here, "break" on the first unit we find that will deactivate, as there's no point in further iteration.
2015-02-25unit: use weaker dependencies between mount and device units in --user modeLennart Poettering
When running in user mode unmounting of mount units when a device vanishes is unlikely to work, and even if it would work is already done by PID 1 anyway. HEnce, when creating implicit dependencies between mount units and their backing devices, created a Wants= type dependency in --user mode, but leave a BindsTo= dependency in --system mode.
2015-02-23remove unused includesThomas Hindoe Paaboel Andersen
This patch removes includes that are not used. The removals were found with include-what-you-use which checks if any of the symbols from a header is in use.
2015-02-12include <poll.h> instead of <sys/poll.h>Thomas Hindoe Paaboel Andersen
include-what-you-use automatically does this and it makes finding unnecessary harder to spot. The only content of poll.h is a include of sys/poll.h so should be harmless.
2015-02-12core: don't fail to run services in --user instances if $HOME is missingLennart Poettering
Otherwise we cannot even invoke systemd-exit.service anymore, thus not even exit. https://bugs.freedesktop.org/show_bug.cgi?id=83100 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=759320
2015-02-11core: correct a log messageLennart Poettering
The log message talks specifically about services, though it actually applies to any kind of unit.
2015-02-03util: rework strappenda(), and rename it strjoina()Lennart Poettering
After all it is now much more like strjoin() than strappend(). At the same time, add support for NULL sentinels, even if they are normally not necessary.
2015-02-01Add a snprinf wrapper which checks that the buffer was big enoughZbigniew Jędrzejewski-Szmek
If we scale our buffer to be wide enough for the format string, we should expect that the calculation was correct. char_array_0() invocations are removed, since snprintf nul-terminates the output in any case. A similar wrapper is used for strftime calls, but only in timedatectl.c.
2015-01-28core: output unit status output strings to console, only if we actually are ↵Lennart Poettering
changing unit state Unit _start() and _stop() implementations can fail with -EAGAIN to delay execution temporarily. Thus, we should not output status messages before invoking these calls, but after, and only when we know that the invocation actually made a change.
2015-01-06core: add new logic for services to store file descriptors in PID 1Lennart Poettering
With this change it is possible to send file descriptors to PID 1, via sd_pid_notify_with_fds() which PID 1 will store individually for each service, and pass via the usual fd passing logic on next invocation. This is useful for enable daemon reload schemes where daemons serialize their state to /run, push their fds into PID 1 and terminate, restoring their state on next start from the data in /run and passed in from PID 1. The fds are kept by PID 1 as long as no POLLHUP or POLLERR is seen on them, and the service they belong to are either not dead or failed, or have a job queued.
2015-01-05core: rework counting of running jobsLennart Poettering
Let's unify the code that counts the running jobs a bit, in order to make sure we are less likely to miss one. This is related to this bug: https://bugs.freedesktop.org/show_bug.cgi?id=87349 However, it probably won't fix it fully, and I cannot reproduce the issue. The change also adds an explicit assert change when the counter is off.

2014-12-16Move dropin listing to sharedZbigniew Jędrzejewski-Szmek
No functional change. This is in preparation for using this in systemctl in the future.
2014-12-15unit: handle nicely of certain unit types are not supported on specific systemsLennart Poettering
Containers do not really support .device, .automount or .swap units; Systems compiled without support for swap do not support .swap units; Systems without kdbus do not support .busname units. With this change attempts to start a unsupported unit types will result in an immediate "unsupported" job result, which is a lot more descriptive then before. Also, attempts to start device units in containers will now immediately fail instead of causing jobs to be enqueued that never go away.
2014-12-10sd-bus: move common errors src/shared/bus-errors.h → ↵Lennart Poettering
src/libsystemd/sd-bus/bus-common-errors.h Stuff in src/shared/ should not use stuff from src/libsystemd/ really.
2014-12-09unit: update unit dropin paths and time when dropin file is written.WaLyong Cho
If a unit is set property by "systemctl set-property", a new dropin file is generated. But the unit's dropin_paths and dropin_mtime are not updated. So the unit is shown as need daemon reload. Update unit dropin_paths and dropin_mtime also when dropin file is written.
2014-12-09core: rename unit_destroy_cgroup() to unit_destroy_cgroup_if_empty() since ↵Lennart Poettering
it's not quite as destructive as it sounds nowadays
2014-12-02systemctl: show unit file preset state in "systemctl status" output"Lennart Poettering
2014-11-28core: convert log_unit_*() to log_unit_*_errno()Michal Schmidt
Using: find . -name '*.[ch]' | xargs sed -r -i -e \ 's/log_unit_(debug|info|notice|warning|error|emergency)\(([^"]+), "(.*)%s"(.*), strerror\(-([a-zA-Z_]+)\)\);/log_unit_\1_errno(\2, \5, "\3%m"\4);/'
2014-11-28log: fix order of log_unit_struct() to match other logging callsLennart Poettering
Also, while we are at it, introduce some syntactic sugar for creating ERRNO= and MESSAGE= structured logging fields.
2014-11-27log: rearrange log function namingLennart Poettering
- Rename log_meta() → log_internal(), to follow naming scheme of most other log functions that are usually invoked through macros, but never directly. - Rename log_info_object() to log_object_info(), simply because the object should be before any other parameters, to follow OO-style programming style.
2014-11-06core: get rid of condition.c and move the remaining call into util.cLennart Poettering
That way only one file with condition code remaining, in src/shared/, rather than src/core/. Next step: dropping the "-util" suffix from condition-util.[ch].
2014-11-06core: introduce the concept of AssertXYZ= similar to ConditionXYZ=, but ↵Lennart Poettering
fatal for a start job if not met
2014-10-30Convert the rest to sd_bus_errnomapZbigniew Jędrzejewski-Szmek
I tried to preserve most errno values, but in some cases they were inconsistent (different errno values for the same error name) or just mismatched.
2014-10-28core: send sigabrt on watchdog timeout to get the stacktraceUmut Tezduyar Lindskog
if sigabrt doesn't do the job, follow regular shutdown routine, sigterm > sigkill.
2014-10-27manager: convert ephemeral to enumZbigniew Jędrzejewski-Szmek
In preparation for subsequent changes.
2014-10-28job: optionally, when a job timeout is hit, also execute a failure actionLennart Poettering
2014-10-23unit: adjust for the possibility of set_move() failingMichal Schmidt
2014-10-23unit: place reservations before merging other's dependenciesMichal Schmidt
With the hashmap implementation that uses chaining the reservations merely ensure that the merging won't result in long bucket chains. With a future alternative implementation it will additionally reserve memory to make sure the merging won't fail.
