2016-08-20machinectl: print OS release in `machinectl list` (#3975)Seraphime
2016-08-04util-lib: rework /tmp and /var/tmp handling codeLennart Poettering
Beef up the existing var_tmp() call, rename it to var_tmp_dir() and add a matching tmp_dir() call (the former looks for the place for /var/tmp, the latter for /tmp). Both calls check $TMPDIR, $TEMP, $TMP, following the algorithm Python3 uses. All dirs are validated before use. secure_getenv() is used in order to limite exposure in suid binaries. This also ports a couple of users over to these new APIs. The var_tmp() return parameter is changed from an allocated buffer the caller will own to a const string either pointing into environ[], or into a static const buffer. Given that environ[] is mostly considered constant (and this is exposed in the very well-known getenv() call), this should be OK behaviour and allows us to avoid memory allocations in most cases. Note that $TMPDIR and friends override both /var/tmp and /tmp usage if set.
2016-08-01machinectl: hide legend in a case when no data (#3839)0xAX
For this moment machinectl prints legend and count of machines/images/etc. But in a case when we have no images,machines,etc., there is no sense to show legend: ~$ machinectl MACHINE CLASS SERVICE 0 machines listed. Let's print only 'No machines', 'No images', 'No transfers' in this case.
2016-07-22tree-wide: use sd_id128_is_null() instead of sd_id128_equal where appropriateLennart Poettering
It's a bit easier to read because shorter. Also, most likely a tiny bit faster.

machinectl: interpret options placed between "shell" verb and machine name
2016-06-26machinectl: verify image existance on "start" and "enable" (#3579)Lennart Poettering
Let's make sure we catch early when a machine doesn't exist that is attempted to be started or enabled as system service.
2016-06-24machined: make sure CleanPool() method is opened up in the dbus policyLennart Poettering
The method is already hooked up to PolicyKit, hence let's open this up via the bus policy language too. Fixes: #3585
2016-06-24machined: "machinectl clean" can take a while, do it asynchronously from a ↵Lennart Poettering
background process This is a follow-up to 5d2036b5f3506bd0ff07042aee8d69c26db32298, and also makes the "machinectl clean" verb asynchronous, after all it's little more than a series of image removals. The changes required to make this happen are a bit more comprehensive as we need to pass information about deleted images back to the client, as well as information about the image we failed on if we failed on one. Hence, create a temporary file in /tmp, serialize that data into, and read it from the parent after the operation is complete.
2016-06-24machined: don't bother explicitly closing the errno pipeLennart Poettering
There's no point in explicitly closing the errno pipe, if we exit right after anyway. It doesn't hurt doing this either, but let's do this the same way for all cases where we use the "Operation" object right now, and in all other cases we do not close the pipe explicitly, hence don't do so here either.
2016-06-22machinectl: do not escape the unit name (#3554)Elias Probst
Otherwise starting a machine named `foo-bar-baz` will end up in machinectl attempting to start the service unit `systemd-nspawn@foo\x2dbar\x2dbaz` instead of `systemd-nspawn@foo-bar-baz`.
2016-06-21machinectl: interpret options placed between "shell" verb and machine nameLennart Poettering
Previously, we'd stop processing of the argument list immediately when hitting the "shell" verb. However, we really should continue processing options then, until we hit the machine name. Fixes: #3472
2016-06-16systemctl: make sure we terminate the bus connection first, and then close ↵Lennart Poettering
the pager (#3550) If "systemctl -H" is used, let's make sure we first terminate the bus connection, and only then close the pager. If done in this order ssh will get an EOF on stdin (as we speak D-Bus through ssh's stdin/stdout), and then terminate. This makes sure the standard error we were invoked on is released by ssh, and only that makes sure we don't deadlock on the pager which waits for all clients closing its input pipe. (Similar fixes for the various other xyzctl tools that support both pagers and -H) Fixes: #3543

and make use of it everywhere
2016-05-26{machine,system}ctl: always pass &changes and &n_changes (#3350)Christian Hesse
We have to pass addresses of changes and n_changes to bus_deserialize_and_dump_unit_file_changes(). Otherwise we are hit by missing information (subsequent calls to unit_file_changes_add() to not add anything). Also prevent null pointer dereference in bus_deserialize_and_dump_unit_file_changes() by asserting. Fixes #3339
2016-05-02machinectl: since clone/remove/copy verbs are possibly slow, turn off bus ↵Lennart Poettering
call timeout By default we timeout all bus calls, but if we know that these bus calls might be slow, let's explicitly turn the timeouts off.
2016-05-02machined: rework copy-from/copy-to operation to use generic Operation objectLennart Poettering
With this all potentially slow operations are done out-of-process, asynchronously, using the same "Operation" object.
2016-05-02machined: also make image removal operation asynchronousLennart Poettering
If we remove a directory image (i.e. not a btrfs snapshot) then things might get quite expensive, hence run this asynchronous in a forked off process, too.
2016-05-02util: rework sigkill_wait() to not require pid_t pointerLennart Poettering
Let's make sigkill_wait() take a normal pid_t, and add sigkill_waitp() that takes a pointer (which is useful for usage in _cleanup_), following the usual logic we have for this.
2016-05-02machined: run clone operation asynchronously in the backgroundLennart Poettering
Cloning an image can be slow, if the image is not on a btrfs subvolume, hence let's make sure we do this asynchronously in a child process, so that machined isn't blocked as long as we process the client request. This adds a new, generic "Operation" object to machined, that is used to track these kind of background processes. This is inspired by the MachineOperation object that already exists to make copy operations asynchronous. A later patch will rework the MachineOperation logic to use the generic Operation instead.

It's better to avoid having the option string duplicated, lest we forget to modify them in sync in the future.

2016-04-25machined: generate a nicer error when the user tries "machinectl clone" on ↵Lennart Poettering
non-btrfs file systems (#3117) Fixes: #2060 (Of course, in the long run, we should probably add a copy-based fall-back. But given how slow that is, this probably requires some asynchronous forking logic like the CopyFrom() and CopyTo() method calls already implement.)
2016-04-25machined: add new OpenRootDirectory() call to Machine objectsLennart Poettering
This new call returns a file descriptor for the root directory of a container. This file descriptor may then be used to access the rest of the container's file system, via openat() and similar calls. Since the file descriptor returned is for the file system namespace inside of the container it may be used to access all files of the container exactly the way the container itself would see them. This is particularly useful for containers run directly from loopback media, for example via systemd-nspawn's --image= switch. It also provides access to directories such as /run of a container that are normally not accessible to the outside of a container. This replaces PR #2870. Fixes: #2870

2016-04-22loginctl,machinectl: also make use of new GetProcesses() bus callLennart Poettering
This ports over machinectl and loginctl to also use the new GetProcesses() bus call to show the process tree of a container or login session. This is similar to how systemctl already has been ported over in a previous commit.

tree-wide: merge pager_open_if_enabled() to the pager_open()
2016-02-26tree-wide: merge pager_open_if_enabled() to the pager_open()Alexander Kuleshov
Many subsystems define own pager_open_if_enabled() function which checks '--no-pager' command line argument and open pager depends on its value. All implementations of pager_open_if_enabled() are the same. Let's merger this function with pager_open() from the shared/pager.c and remove pager_open_if_enabled() from all subsytems to prevent code duplication.
