2015-11-13analyze: do not draw ConflictedBy dependencies in dot graphMichal Schmidt
We already draw Conflicts. I see no reason for having every red line in the graph duplicated in the opposite direction.
2015-11-13analyze: show Requisite dependencies in the dot graph againMichal Schmidt
We lost them a long time ago with commit 048ecf5b843.
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.

2015-09-30analyze: add new set-log-target subcommandLennart Poettering
We already have the property writable, hence let's add a command to set 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.
2015-09-22cgtop: underline table headerLennart Poettering
Let's underline the header line of the table shown by cgtop, how it is customary for tables. In order to do this, let's introduce new ANSI underline macros, and clean up the existing ones as side effect.

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.

2015-02-16analyze: change behaviour of combined --to/from--patternZbigniew Jędrzejewski-Szmek
We would require a match against all three: patterns specified with --to, with --from, and as positional arguments to show an edge. This does not seem useful. Let instead the positional args behave like they were specified in both --to and --from, which is fairly intuitive and should be more useful.

2014-12-24sd-bus: rename sd_bus_open_system_container() to sd_bus_open_system_machine()Lennart Poettering
Pretty much everywhere else we use the generic term "machine" when referring to containers in API, so let's do though in sd-bus too. In particular, since the concept of a "container" exists in sd-bus too, but as part of the marshalling system.
2014-11-28treewide: no need to negate errno for log_*_errno()Michal Schmidt
It corrrectly handles both positive and negative errno values.
2014-11-28treewide: auto-convert the simple cases to log_*_errno()Michal Schmidt
As a followup to 086891e5c1 "log: add an "error" parameter to all low-level logging calls and intrdouce log_error_errno() as log calls that take error numbers", use sed to convert the simple cases to use the new macros: find . -name '*.[ch]' | xargs sed -r -i -e \ 's/log_(debug|info|notice|warning|error|emergency)\("(.*)%s"(.*), strerror\(-([a-zA-Z_]+)\)\);/log_\1_errno(-\4, "\2%m"\3);/' Multi-line log_*() invocations are not covered. And we also should add log_unit_*_errno().
2014-09-15hashmap: introduce hash_ops to make struct Hashmap smallerMichal Schmidt
It is redundant to store 'hash' and 'compare' function pointers in struct Hashmap separately. The functions always comprise a pair. Store a single pointer to struct hash_ops instead. systemd keeps hundreds of hashmaps, so this saves a little bit of memory.

2014-09-11analyze: avoid a null dereferenceThomas Hindoe Paaboel Andersen
If we have an error in the early sd_bus_* calls then unit_times will still be null. Found with coverity. Fixes: CID#996464
2014-08-20cmdline: for new tools avoid introduce new negative switches, and properly ↵Lennart Poettering
align --help texts Negative switches are a bad un-normalized thing. We alerady have some, but we should try harder to avoid intrdoucing new ones. Hence, instead of adding two switches: --foobar --no-foobar Let's instead use the syntax --foobar --foobar=yes --foobar=no Where the first two are equivalent. The boolean argument is parsed following the usual rules. Change all new negative switches this way. This patch also properly aligns the --help table, so that single char switches always get a column separate of the long switches.

2014-08-04bus: always explicitly close bus from main programsLennart Poettering
Since b5eca3a2059f9399d1dc52cbcf9698674c4b1cf0 we don't attempt to GC busses anymore when unsent messages remain that keep their reference, when they otherwise are not referenced anymore. This means that if we explicitly want connections to go away, we need to close them. With this change we will no do so explicitly wherver we connect to the bus from a main program (and thus know when the bus connection should go away), or when we create a private bus connection, that really should go away after our use. This fixes connection leaks in the NSS and PAM modules.
2014-08-03Unify parse_argv styleZbigniew Jędrzejewski-Szmek
getopt is usually good at printing out a nice error message when commandline options are invalid. It distinguishes between an unknown option and a known option with a missing arg. It is better to let it do its job and not use opterr=0 unless we actually want to suppress messages. So remove opterr=0 in the few places where it wasn't really useful. When an error in options is encountered, we should not print a lengthy help() and overwhelm the user, when we know precisely what is wrong with the commandline. In addition, since help() prints to stdout, it should not be used except when requested with -h or --help. Also, simplify things here and there.

2014-05-26analyze/run: use bus_open_transport_systemd instead of bus_open_transportThomas Bächler
Both systemd-analyze and systemd-run only access org.freedesktop.systemd1 on the bus. This patch allows using systemd-run --user and systemd-analyze --user even if the user session's bus is not properly integrated with the systemd user unit. https://bugs.freedesktop.org/show_bug.cgi?id=79252 and other reports...

2014-04-23analyze: fix plot with bad y sizeJeffrey Clark
systemd-analyze plot > test.svg produces output with all y and height element attributes equal to zero. This of course causes the resulting svg to appear blank (zero height). Bug does not affect x86.
