2016-09-13tree-wide: use %m in calls to sd_bus_error_set_errnofZbigniew Jędrzejewski-Szmek
sd_bus_error_set_errnof supports %m, so there's no need to call strerror manually.

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
2016-06-11test-keymap-util: use kbd-model-map/language-fallback-map from $(srcdir)Zbigniew Jędrzejewski-Szmek
This adds (undocumented) environment variables SYSTEMD_KBD_MODEL_MAP and SYSTEMD_LANGUAGE_FALLBACK_MAP, which, if set, override compiled-in locations of those two files. Instead of skipping tests when the maps are not installed, just use the one from the source dir. We still cannot do the mappings the other way if /usr/lib/kbd/keymaps is not present, so truncate the tests in that case. Also tweak the debug messages a bit to make it easier to see which function is failing.
2016-06-06keymap-util: also "convert" 'ru' to 'ru'Zbigniew Jędrzejewski-Szmek
As discovered by Adam Williamson in https://bugzilla.redhat.com/show_bug.cgi?id=1333998#c32, after the changes in 81fd105a5f9 we would only match compound layouts, i.e. a comma would be required after 'ru' to match. This seems wrong, and we should match single layouts like too. So 'ru', 'ru,us' now both match. startswith_comma is changed to not require a comma, i.e. check that the prefix matches until a comma or the end of the string. Note that startswith_comma is called twice. At the first site, we check that strings are not equal beforehand, so this change to startswith_comma has no effect. At the second site, it does have an effect, as described above.
2016-06-06localed: also report when we couldn't convert X11→consoleZbigniew Jędrzejewski-Szmek
Rework the code a bit where find_converted_keymap cannot (and should not) be called with a null layout, so streq can be used instead of streq_ptr, etc. Note that the behaviour of vconsole_convert_to_x11 and x11_convert_to_vconsole is not symmetrical. When the latter cannot find a match, it simply makes the vconsole mapping empty. But vconsole_convert_to_x11 leaves the x11 layout unchanged. I don't know what the proper solution is here, so I'm just adding more verbose logging without changing the logic.
2016-06-06localed: be more verbose when keymap conversion to X11 failsZbigniew Jędrzejewski-Szmek
I was puzzled why "localectl set-keymap pl" does not change the X11 keymap. Output a message at notice level, becuase not converting the X11 keymap is most likely an error. We usually do not output non-debug messages from "library" code, but this isn't really library code, it's split out to a separate file only to allow it to be called from tests. (pl is not converted because we only have a mapping for pl2. This is intentional, even though we might want to change this. In any case, the conversion code works correctly.)
2016-06-06keymap-util: add tests and fix one small bugZbigniew Jędrzejewski-Szmek
When converting an empty x11 variant, we would not delete vconsole mapping properly. find_legacy_keymap() is made non-static. I think it's important to be able to test it. In principle we could also test it through the higher-level interface of x11_convert_to_vconsole, but x11_convert_to_vconsole also uses find_converted_keymap, and it's better to test at this lower level. Note that find_legacy_keymap might be a bit of a misnomer, because we'd probably want to keep kbd-model-map even if the "legacy" layouts went away. So we might want to change this name, but I'm leaving that for another commit.
2016-06-06localed: split out keymap parsing to a separate fileZbigniew Jędrzejewski-Szmek
This way the dbus and management logic is seperated from the business logic and we can write test cases for the mapping functionality.

2016-04-12localed: downgrade libxkbcommon to an optional runtime dependencyLennart Poettering
Previously, libxkbcommon was a compile-time option. When enabled the localed binary would strictly depend on it, thus pulling in libxkbcommon and its dependencies, which are non-trivial in size. With this change we dlopen() libxkbcommon when it is available instead. If the library is available behaviour is as before. However, if it isn't the system is considered "headless", i.e. without local hardware and all attempts to set the local keyboard configuration will be refused. This is useful for general-purpose distributions which want to support "headless" (such as container systems) and "full" systems with the same build.
2016-03-24localectl: align output of 'localectl status' commandYu Watanabe
If kernel command line options for locale are given, the output of 'localectl status' command is not aligned, for example, ============= Warning: Settings on kernel command line override system locale settings in /etc/locale.conf. Command Line: LANG=C System Locale: LANG=C VC Keymap: n/a X11 Layout: n/a ============= This commit fixes the alignment.
2016-03-24localectl: remove unnecessary line breakYu Watanabe
If /etc/locale.conf is empty or does not exist, the output of 'localectl status' command includes an unnecessary line break as follows: ======================= System Locale: n/a VC Keymap: n/a X11 Layout: n/a ======================= This commit removes the line break after the system locale.

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.
2016-02-22tree-wide: make ++/-- usage consistent WRT spacingVito Caputo
Throughout the tree there's spurious use of spaces separating ++ and -- operators from their respective operands. Make ++ and -- operator consistent with the majority of existing uses; discard the spaces.

This should be handled fine now by .dir-locals.el, so need to carry that stuff in every file.
2016-01-13tree-wide: check if errno is greater then zeroZbigniew Jędrzejewski-Szmek
gcc is confused by the common idiom of return errno ? -errno : -ESOMETHING and thinks a positive value may be returned. Replace this condition with errno > 0 to help gcc and avoid many spurious warnings. I filed a gcc rfe a long time ago, but it hard to say if it will ever be implemented [1]. Both conventions were used in the codebase, this change makes things more consistent. This is a follow up to bcb161b0230f. [1] https://gcc.gnu.org/bugzilla/show_bug.cgi?id=61846
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.

2015-09-29bus-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.
2015-09-09locale: kill free_and_replace()Daniel Mack
That function really makes little sense, as the open-coded variant is much more readable. Also, if the 2nd argument is NULL, mfree() is a much better candidate. Convert the only users of this function in localed, and then remove it entirely.
2015-09-07basic: rework virtualization detection APILennart Poettering
Introduce a proper enum, and don't pass around string ids anymore. This simplifies things quite a bit, and makes virtualization detection more similar to architecture detection.

strv_split_extract is to strv_split_quotes as extract_first_word was to unquote_first_word. Now there's extract_first_word for extracting a single argument, extract_many_words for extracting a bounded number of arguments, and strv_split_extract for extracting an arbitrary number of arguments.

Tests are modified to check behaviour with relax and without relax. New tests are added for hostname_cleanup(). Tests are moved a new file (test-hostname-util) because there's now a bunch of them. New parameter is not used anywhere, except in tests, so there should be no observable change.

2015-07-29tree-wide: port everything over to fflush_and_check()Lennart Poettering
Some places invoked fflush() directly with their own manual error checking, let's unify all that by using fflush_and_check(). This also unifies the general error paths of fflush()+rename() file writers.
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
2015-06-14tree-wide: fix memory leaks in users of bus_map_all_properties()David Herrmann
If you use bus_map_all_properties(), you must be aware that it might touch output variables even though it may fail. This is, because we parse many different bus-properties and cannot tell how to clean them up, in case we fail deep down in the parser. Fix all callers of bus_map_all_properties() to correctly cleanup any context structures at all times.

2015-04-29sd-bus: drop bus parameter from message callback prototypeLennart Poettering
This should simplify the prototype a bit. The bus parameter is redundant in most cases, and in the few where it matters it can be derived from the message via sd_bus_message_get_bus().
2015-03-26util: rework word parsing and c unescaping codeLennart Poettering
When parsing words from input files, optionally automatically unescape the passed strings, controllable via a new flags parameter. Make use of this in tmpfiles, and port everything else over, too. This improves parsing quite a bit, since we no longer have to process the same string multiple times with different calls, where an earlier call might corrupt the input for a later call.
