2017-02-09tree-wide: make bus_map_all_properties return a proper sd_bus_errorLennart Poettering
And then show it, to make things a bit friendlier to the user if we fail acquiring some props. In fact, this fixes a number of actual bugs, where we used an error structure for output that we actually never got an error in.

2016-10-01analyze-verify: honour $SYSTEMD_UNIT_PATH, allow system paths to be ignoredZbigniew Jędrzejewski-Szmek
SYSTEMD_UNIT_PATH=foobar: systemd-analyze verify barbar/unit.service will load units from barbar/, foobar/, /etc/systemd/system/, etc. SYSTEMD_UNIT_PATH= systemd-analyze verify barbar/unit.service will load units only from barbar/, which is useful e.g. when testing systemd's own units on a system with an older version of systemd installed.

2016-05-09tree-wide: rename draw_special_char to special_glyphZbigniew Jędrzejewski-Szmek
That function doesn't draw anything on it's own, just returns a string, which sometimes is more than one character. Also remove "DRAW_" prefix from character names, TREE_* and ARROW and BLACK_CIRCLE are unambigous on their own, don't draw anything, and are always used as an argument to special_glyph(). Rename "DASH" to "MDASH", as there's more than one type of dash.
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.
2016-04-12core: remove ManagerRunningAs enumLennart Poettering
Previously, we had two enums ManagerRunningAs and UnitFileScope, that were mostly identical and converted from one to the other all the time. The latter had one more value UNIT_FILE_GLOBAL however. Let's simplify things, and remove ManagerRunningAs and replace it by UnitFileScope everywhere, thus making the translation unnecessary. Introduce two new macros MANAGER_IS_SYSTEM() and MANAGER_IS_USER() to simplify checking if we are running in one or the user context.

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.

2016-02-20tree-wide: place #pragma once at the same place everywhereLennart Poettering
Usually, we place the #pragma once before the copyright blurb in header files, but in a few cases we didn't. Move those around, so that we do the same thing everywhere.

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.

We already draw Conflicts. I see no reason for having every red line in the graph duplicated in the opposite direction.

We lost them a long time ago with commit 048ecf5b843.
2015-11-12core: drop "override" flag when building transactionsLennart Poettering
Now that we don't have RequiresOverridable= and RequisiteOverridable= dependencies anymore, we can get rid of tracking the "override" boolean for jobs in the job engine, as it serves no purpose anymore. While we are at it, fix some error messages we print when invoking functions that take the override parameter.
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.

2015-09-29bus-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.

2015-07-28analyze: correctly draw the plot for user instancesIvan Shapovalov
Start-up timestamp of a user instance (userspace_time in struct boot_times) actually may be arbitrarily big. This, because all timestamps are offset by that value, leads to creation of arbitrarily wide SVGs which almost completely consist of blank space. Fix this by inverse-offsetting all timestamps by that value if user instance operation is requested. Fixes #740.
2015-07-28analyze: move acquire_boot_times() above acquire_time_data()Ivan Shapovalov
Next patch will make the latter call into the former.
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
2015-05-11core: 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.
2015-05-11core,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
