* tree-wide: remove Lennart's copyright linesLennart Poettering2018-06-141-3/+0
| | | | | | | | | | | These lines are generally out-of-date, incomplete and unnecessary. With SPDX and git repository much more accurate and fine grained information about licensing and authorship is available, hence let's drop the per-file copyright notice. Of course, removing copyright lines of others is problematic, hence this commit only removes my own lines and leaves all others untouched. It might be nicer if sooner or later those could go away too, making git the only and accurate source of authorship information.
* tree-wide: drop 'This file is part of systemd' blurbLennart Poettering2018-06-141-2/+0
| | | | | | | | | | | | | | | | This part of the copyright blurb stems from the GPL use recommendations: https://www.gnu.org/licenses/gpl-howto.en.html The concept appears to originate in times where version control was per file, instead of per tree, and was a way to glue the files together. Ultimately, we nowadays don't live in that world anymore, and this information is entirely useless anyway, as people are very welcome to copy these files into any projects they like, and they shouldn't have to change bits that are part of our copyright header for that. hence, let's just get rid of this old cruft, and shorten our codebase a bit.
* tree-wide: drop license boilerplateZbigniew Jędrzejewski-Szmek2018-04-061-13/+0
| | | | | | | | | | Files which are installed as-is (any .service and other unit files, .conf files, .policy files, etc), are left as is. My assumption is that SPDX identifiers are not yet that well known, so it's better to retain the extended header to avoid any doubt. I also kept any copyright lines. We can probably remove them, but it'd nice to obtain explicit acks from all involved authors before doing that.

* tree-wide: make use of getpid_cached() wherever we canLennart Poettering2017-07-201-2/+3
| | | | | | | This moves pretty much all uses of getpid() over to getpid_raw(). I didn't specifically check whether the optimization is worth it for each replacement, but in order to keep things simple and systematic I switched over everything at once.

* tree-wide: expose "p"-suffix unref calls in public APIs to make gcc cleanup easyLennart Poettering2015-11-271-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* util-lib: split out allocation calls into alloc-util.[ch]Lennart Poettering2015-10-271-5/+6

* bus-util: rename bus_open_transport() to bus_connect_transport()Lennart Poettering2015-09-291-1/+1
| | | | | | | | | | | | | | 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.

* tree-wide: make use of log_error_errno() return valueLennart Poettering2015-09-091-6/+6
| | | | | | | | | | | | | | | | | | | | Turns this: r = -errno; log_error_errno(errno, "foo"); into this: r = log_error_errno(errno, "foo"); and this: r = log_error_errno(errno, "foo"); return r; into this: return log_error_errno(errno, "foo");
* Bug #944: Deletion of unnecessary checks before a few calls of systemd functionsMarkus Elfring2015-08-171-3/+1
| | | | | | | | | | | | | | | The following functions return immediately if a null pointer was passed. * calendar_spec_free * link_address_free * manager_free * sd_bus_unref * sd_journal_close * udev_monitor_unref * udev_unref It is therefore not needed that a function caller repeats a corresponding check. This issue was fixed by using the software Coccinelle 1.0.1.

* remove unused includesThomas Hindoe Paaboel Andersen2015-02-231-2/+0

* everywhere: remove configurability of sysv runlevel to target mappingLennart Poettering2015-02-181-5/+3
| | | | | | | | | | | | | | | With this change runlevel 2, 3, 4 are mapped to multi-user.target for good, and 5 to graphical.target. This was already the previous mapping but is now no longer reconfigurable, but hard-coded into the core. This should generally simplify things, but also fix one bug: the sysv-generator previously generated symlinks to runlevel[2-5].target units, which possibly weren't picked up if these aliases were otherwise only referenced by the real names "multi-user.target" and "graphical.target". We keep compat aliases "runlevel[2345].target" arround for cases where this target name is explicitly requested.
* treewide: use log_*_errno whenever %m is in the format stringMichal Schmidt2014-11-281-4/+4
| | | | | | | | | | | If the format string contains %m, clearly errno must have a meaningful value, so we might as well use log_*_errno to have ERRNO= logged. Using: find . -name '*.[ch]' | xargs sed -r -i -e \ 's/log_(debug|info|notice|warning|error|emergency)\((".*%m.*")/log_\1_errno(errno, \2/' Plus some whitespace, linewrap, and indent adjustments.
* treewide: yet more log_*_errno + return simplificationsMichal Schmidt2014-11-281-4/+2
| | | | | | | | | | | | | Using: find . -name '*.[ch]' | while read f; do perl -i.mmm -e \ 'local $/; local $_=<>; s/(if\s*\([^\n]+\))\s*{\n(\s*)(log_[a-z_]*_errno\(\s*([->a-zA-Z_]+)\s*,[^;]+);\s*return\s+\g4;\s+}/\1\n\2return \3;/msg; print;' $f done And a couple of manual whitespace fixups.
* treewide: no need to negate errno for log_*_errno()Michal Schmidt2014-11-281-5/+5
| | | | It corrrectly handles both positive and negative errno values.
* treewide: auto-convert the simple cases to log_*_errno()Michal Schmidt2014-11-281-5/+5
| | | | | | | | | | | | | 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().

* utmp: turn systemd-update-utmp-shutdown.service into a normal runtime serviceLennart Poettering2013-05-161-1/+1
| | | | | | | | | | With this change systemd-update-utmp-shutdown.service is replaced by systemd-update-utmp.service which is started at boot and stays around until shutdown. This allows us to properly order the unit against both /var/log and auditd. https://bugzilla.redhat.com/show_bug.cgi?id=853104 https://bugs.freedesktop.org/show_bug.cgi?id=64365
* Use initalization instead of explicit zeroingZbigniew Jędrzejewski-Szmek2013-04-051-2/+1
| | | | | | | | | | | | | | | | | | | | | | | Before, we would initialize many fields twice: first by filling the structure with zeros, and then a second time with the real values. We can let the compiler do the job for us, avoiding one copy. A downside of this patch is that text gets slightly bigger. This is because all zero() calls are effectively inlined: $ size build/.libs/systemd text data bss dec hex filename before 897737 107300 2560 1007597 f5fed build/.libs/systemd after 897873 107300 2560 1007733 f6075 build/.libs/systemd … actually less than 1‰. A few asserts that the parameter is not null had to be removed. I don't think this changes much, because first, it is quite unlikely for the assert to fail, and second, an immediate SEGV is almost as good as an assert.
