2016-02-15systemctl: fix style to avoid modification of array passed by callerZbigniew Jędrzejewski-Szmek

2016-02-15systemctl: include -M or -H arguments in the hintZbigniew Jędrzejewski-Szmek
https://github.com/systemd/systemd/issues/2431 Some newlines are added, but the output will still exceed 80 columns in many cases. The fallback for oom conditions is changed from "n/a" to something "<service>", and a similar pattern is used for the new code. This way we have a realistic fallback for oom, which seems nicer than making the whole function return an error code which would then have to be propagated. $ systemctl -M fedora-rawhide restart systemd-networkd.service Job for systemd-networkd.service failed because start of the service was attempted too often. See "systemctl -M fedora-rawhide status systemd-networkd.service" and "journalctl -M fedora-rawhide -xe" for details. To force a start use "systemctl -M fedora-rawhide reset-failed systemd-networkd.service" followed by "systemctl -M fedora-rawhide start systemd-networkd.service" again.

2016-02-01core: fix support for transient resource limit propertiesLennart Poettering
Make sure we can properly process resource limit properties. Specifically, allow transient configuration of both the soft and hard limit, the same way from the unit files. Previously, only the the hard rlimits could be configured but they'd implicitly spill into the soft hard rlimits. This also updates the client-side code to be able to parse hard/soft resource limit specifications. Since we need to serialize two properties in bus_append_unit_property_assignment() now, the marshalling of the container around it is now moved into the function itself. This has the benefit of shortening the calling code. As a side effect this now beefs up the rlimit parser of "systemctl set-property" to understand time and disk sizes where that's appropriate.

2016-01-28systemctl: rename "reload-or-try-restart" verb to "try-reload-or-restart"Lennart Poettering
But also keep the old name as (undocumented) compatibility around. The reload-or-try-restart was documented to be a NOP if the unit is not running, since the previous commits this is also implemented. The old name suggests that the "try" logic only applies to restarting. Fix this, by moving the "try-" to the front, to indicate that the whole option is a NOP if the service isn't running.
2016-01-28systemctl: don't make up unit states, and don't eat up errors to eagerlyLennart Poettering
When checking a unit's state, don't ignore errors too eagerly, but generate proper error messages. Also, don't synthesize an "unknown" state on error, but let the operation file. If a unit file isn't loaded treat this as "inactive" as that's effectively what it means.
2016-01-28systemctl: don't mangle unit names in check_unit_generic()Lennart Poettering
As it turns out all callers of check_unit_generic() already mangle unit names, or get the unit names directly from PID 1 (and hence arein normalized form anyway), hence there's no point in mangling then...

2016-01-21systemctl: Allow 'edit' and 'cat' on unloaded unitsDouglas Christman
Don't fail if the unit has a LoadError; otherwise `systemctl edit` cannot be used to correct the error (e.g. multiple "ExecStart=" lines). Remove file changed warning so cat output isn't interspersed with log messages. Fixes #829

2015-11-27tree-wide: expose "p"-suffix unref calls in public APIs to make gcc cleanup easyLennart Poettering
GLIB has recently started to officially support the gcc cleanup attribute in its public API, hence let's do the same for our APIs. With this patch we'll define an xyz_unrefp() call for each public xyz_unref() call, to make it easy to use inside a __attribute__((cleanup())) expression. Then, all code is ported over to make use of this. The new calls are also documented in the man pages, with examples how to use them (well, I only added docs where the _unref() call itself already had docs, and the examples, only cover sd_bus_unrefp() and sd_event_unrefp()). This also renames sd_lldp_free() to sd_lldp_unref(), since that's how we tend to call our destructors these days. Note that this defines no public macro that wraps gcc's attribute and makes it easier to use. While I think it's our duty in the library to make our stuff easy to use, I figure it's not our duty to make gcc's own features easy to use on its own. Most likely, client code which wants to make use of this should define its own: #define _cleanup_(function) __attribute__((cleanup(function))) Or similar, to make the gcc feature easier to use. Making this logic public has the benefit that we can remove three header files whose only purpose was to define these functions internally. See #2008.

2015-11-12core: remove support for RequiresOverridable= and RequisiteOverridable=Lennart Poettering
As discussed at systemd.conf 2015 and on also raised on the ML: http://lists.freedesktop.org/archives/systemd-devel/2015-November/034880.html This removes the two XyzOverridable= unit dependencies, that were basically never used, and do not enhance user experience in any way. Most folks looking for the functionality this provides probably opt for the "ignore-dependencies" job mode, and that's probably a good idea. Hence, let's simplify systemd's dependency engine and remove these two dependency types (and their inverses). The unit file parser and the dbus property parser will now redirect the settings/properties to result in an equivalent non-overridable dependency. In the case of the unit file parser we generate a warning, to inform the user. The dbus properties for this unit type stay available on the unit objects, but they are now hidden from usual introspection and will always return the empty list when queried. This should provide enough compatibility for the few unit files that actually ever made use of this.
2015-11-12install: follow unit file symlinks in /usr, but not /etc when looking for ↵Lennart Poettering
[Install] data Some distributions use alias unit files via symlinks in /usr to cover for legacy service names. With this change we'll allow "systemctl enable" on such aliases. Previously, our rule was that symlinks are user configuration that "systemctl enable" + "systemctl disable" creates and removes, while unit files is where the instructions to do so are store. As a result of the rule we'd never read install information through symlinks, since that would mix enablement state with installation instructions. Now, the new rule is that only symlinks inside of /etc are configuration. Unit files, and symlinks in /usr are now valid for installation instructions. This patch is quite a rework of the whole install logic, and makes the following addional changes: - Adds a complete test "test-instal-root" that tests the install logic pretty comprehensively. - Never uses canonicalize_file_name(), because that's incompatible with operation relative to a specific root directory. - unit_file_get_state() is reworked to return a proper error, and returns the state in a call-by-ref parameter. This cleans up confusion between the enum type and errno-like errors. - The new logic puts a limit on how long to follow unit file symlinks: it will do so only for 64 steps at max. - The InstallContext object's fields are renamed to will_process and has_processed (will_install and has_installed) since they are also used for deinstallation and all kinds of other operations. - The root directory is always verified before use. - install.c is reordered to place the exported functions together. - Stricter rules are followed when traversing symlinks: the unit suffix must say identical, and it's not allowed to link between regular units and templated units. - Various modernizations - The "invalid" unit file state has been renamed to "bad", in order to avoid confusion between UNIT_FILE_INVALID and _UNIT_FILE_STATE_INVALID. Given that the state should normally not be seen and is not documented this should not be a problematic change. The new name is now documented however. Fixes #1375, #1718, #1706

Instead, let the caller do that. Fix this by moving masked unit messages into the caller, by returning a clear error code (ESHUTDOWN) by which this may be detected.

2015-11-10Remove snapshot unit typeZbigniew Jędrzejewski-Szmek
Snapshots were never useful or used for anything. Many systemd developers that I spoke to at systemd.conf2015, didn't even know they existed, so it is fairly safe to assume that this type can be deleted without harm. The fundamental problem with snapshots is that the state of the system is dynamic, devices come and go, users log in and out, timers fire... and restoring all units to some state from the past would "undo" those changes, which isn't really possible. Tested by creating a snapshot, running the new binary, and checking that the transition did not cause errors, and the snapshot is gone, and snapshots cannot be created anymore. New systemctl says: Unknown operation snapshot. Old systemctl says: Failed to create snapshot: Support for snapshots has been removed. IgnoreOnSnaphost settings are warned about and ignored: Support for option IgnoreOnSnapshot= has been removed and it is ignored http://lists.freedesktop.org/archives/systemd-devel/2015-November/034872.html

2015-10-31systemctl: add a way to explicitly request client-side unit installingLennart Poettering
This adds support for a new environment variable SYSTEMCTL_INSTALL_CLIENT_SIDE, that ensures that systemctl executes install operations client-side instead of passing them to PID1. This is useful in debugging situations, but even beyond that. However, we don't want to make it official API, hence let's just make it an undocumented environment variable. Similar, add a second variable, SYSTEMCTL_SKIP_SYSV which allows skipping the SysV chkconfig fall-back if set. This is useful for similar reasons, and exposed as undocumented as environment variable for similar reasons, too.
