2016-08-18bus-util: unify loop around bus_append_unit_property_assignment()Lennart Poettering
This is done exactly the same way a couple of times at various places, let's unify this into one version.
2016-08-05util-lib: unify parsing of nice level valuesLennart Poettering
This adds parse_nice() that parses a nice level and ensures it is in the right range, via a new nice_is_valid() helper. It then ports over a number of users to this. No functional changes.

2016-05-21run: do not try to use reply after freeing it (#3318)Zbigniew Jędrzejewski-Szmek
We'd call sd_bus_message_unref and then proceed to use variables pointing into the reply buffer (fd and char*). dup the fd and copy the string before destorying the reply. This makes systemd-run run again for me. https://bugzilla.redhat.com/show_bug.cgi?id=1337636

2016-04-22shared: move unit-specific code from bus-util.h to bus-unit-util.hLennart Poettering
Previously we'd have generally useful sd-bus utilities in bust-util.h, intermixed with code that is specifically for writing clients for PID 1, wrapping job and unit handling. Let's split the latter out and move it into bus-unit-util.c, to make the sources a bit short and easier to grok.

Keep the previous option name as hidden, for compatibility. Fixes #3054.
2016-04-04run: add colon before printing started unitsIago López Galeiras
In 110ceee58e5bc796c03a7db2109f85a999d5bc2e we removed the period after printing the started units. This makes copying the unit name easier but results in improper English. This adds a colon before printing the units, which makes the output look better.
2016-03-23run: remove period when printing started unitsIago López Galeiras
If you start a unit with systemd-run you usually need its name to inspect it or stop it. Removing the period makes copying the unit name easier.

2016-02-10tree-wide: remove Emacs lines from all filesDaniel Mack
This should be handled fine now by .dir-locals.el, so need to carry that stuff in every file.
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.
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.
2015-11-17run: automatically clean up transient timers created by systemd-runLennart Poettering
2015-11-17run: when automatically generating names for transient units, use unique bus ↵Lennart Poettering
ID, fallback to random Previously we used the process ID to generate transient unit names. However, that is problematic as PIDs get reused easily, and applying them to remote systems makes little sense. Fortunately, each bus peer gets a unique, non-reusable ID assigned when attaching to a bus, hence let's use that, if we can. In some cases we cannot however, because we connect directly to PID's private socket, and thus are not a proper bus peer with a unique ID. In that case generate a random UUID to name the unit after.

There are more than enough to deserve their own .c file, hence move them over.
2015-10-24path-util: rework find_binary(), fsck_exists() and mkfs_exists()Lennart Poettering
Modernize the code a bit: - Get rid of FOREACH_WORD_SEPARATOR() loop in favour of a extract_first_word() loop. - Remove find_binary()'s "local" flag. It's not reasonably possible to look for binaries on remote systems, we hence should not pretend we could. - When we cannot find a suitable binary, return the last error returned from access() rather than ENOENT unconditionally. - Rework fsck_exists() and mkfs_exists() to return 1 on success, 0 if the implementation is missing and negative on real errors. This is more like we do it in other functions. - Make sure we also detect direct fsck symlinks to "true", rather than just absolute ones to /bin/true.

2015-10-07machinectl: fix race when opening new shells with "machinectl shell"Lennart Poettering
Previously, we'd allocate the TTY, spawn a service on it, but immediately start processing the TTY and forwarding it to whatever the commnd was started on. This is however problematic, as the TTY might get actually opened only much later by the service. We'll hence first get EIOs on the master as the other side is still closed, and hence considered it hung up and terminated the session. With this change we add a flag to the pty forwarding logic: PTY_FORWARD_IGNORE_INITIAL_VHANGUP. If set, we'll ignore all hangups (i.e. EIOs) on the master PTY until the first byte is successfully read. From that point on we consider a hangup/EIO a regular connection termination. This way, we handle the race: when we get EIO initially we'll ignore it, until the connection is properly set up, at which time we start honouring it.
2015-09-29bus-util: rename bus_open_transport() to bus_connect_transport()Lennart Poettering
In sd-bus, the sd_bus_open_xyz() family of calls allocates a new bus, while sd_bus_default_xyz() family tries to reuse the thread's default bus. bus_open_transport() sometimes internally uses the former, sometimes the latter family, but suggests it only calls the former via its name. Hence, let's avoid this confusion, and generically rename the call to bus_connect_transport(). Similar for all related calls. And while we are at it, also change cgls + cgtop to do direct systemd connections where possible, since all they do is talk to systemd itself.
2015-09-29util: introduce common version() implementation and use it everywhereLennart Poettering
This also allows us to drop build.h from a ton of files, hence do so. Since we touched the #includes of those files, let's order them properly according to CODING_STYLE.
2015-09-01machined: call unlockpt() in container, not hostLennart Poettering
It makes assumptions about the pty path, hence better call it in the container namespace rather than the host.

Use free_and_strdup() where appropriate and replace equivalent, open-coded versions.
2015-07-03sd-bus: introduce new sd_bus_flush_close_unref() callLennart Poettering
sd_bus_flush_close_unref() is a call that simply combines sd_bus_flush() (which writes all unwritten messages out) + sd_bus_close() (which terminates the connection, releasing all unread messages) + sd_bus_unref() (which frees the connection). The combination of this call is used pretty frequently in systemd tools right before exiting, and should also be relevant for most external clients, and is hence useful to cover in a call of its own. Previously the combination of the three calls was already done in the _cleanup_bus_close_unref_ macro, but this was only available internally. Also see #327
2015-06-15everywhere: port everything to sigprocmask_many() and friendsLennart Poettering
This ports a lot of manual code over to sigprocmask_many() and friends. Also, we now consistly check for sigprocmask() failures with assert_se(), since the call cannot realistically fail unless there's a programming error. Also encloses a few sd_event_add_signal() calls with (void) when we ignore the return values for it knowingly.

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
2015-04-28run: by default, wait until the transient unit finished start-upLennart Poettering
Make this blocking behaviour optional with --no-block, similar to systemctl's switch of this name.
2015-04-28run: synchronously wait until the scope unit we create is startedLennart Poettering
Otherwise it might happen that by the time PID 1 adds our process to the scope unit the process might already have died, if the process is short-running (such as an invocation to /bin/true). https://bugs.freedesktop.org/show_bug.cgi?id=86520

2015-02-18nspawn: when connected to pipes for stdin/stdout, pass them as-is to PID 1Lennart Poettering
Previously we always invoked the container PID 1 on /dev/console of the container. With this change we do so only if nspawn was invoked interactively (i.e. its stdin/stdout was connected to a TTY). In all other cases we directly pass through the fds unmodified. This has the benefit that nspawn can be added into shell pipelines. https://bugs.freedesktop.org/show_bug.cgi?id=87732
