Everything else just is annoying, hence let's list this among the
requirements we make on the kernel in order to minimize confusion
leading to #6184 and suchlike.
The DNS and NTP fallback server situation is pretty similar, and
downstream distros might want to change both to whatever they need,
hence mention them both.
This was done autogen.sh previously and was dropped in
72cdb3e783. Let's add it back.
The meson configuration step is the only reasonable place.
Note that this only works for the most standard git dirs, e.g.
the hook will not be installed if git worktree is used or if
$GIT_DIR is specified, etc. I think that's OK because most of
the time meson will be run at least once in the original cloned
dir.
Some kdbus_flag and memfd related parts are left behind, because they
are entangled with the "legacy" dbus support.
test-bus-benchmark is switched to "manual". It was already broken before
(in the non-kdbus mode) but apparently nobody noticed. Hopefully it can
be fixed later.
Since busname units are only useful with kdbus, they weren't actively
used. This was dead code, only compile-tested. If busname units are
ever added back, it'll be cleaner to start from scratch (possibly reverting
parts of this patch).

This should make it easier to see when any of the units are involved in an
ordering cycle.
Fixes#6336.
v2:
- also update the "Unable to break cycle" message.
This reverts commit 2d058a87ff.
When we add another name to a unit (by following an alias), we need to
reload all drop-ins. This is necessary to load any additional dropins
found in the dirs created from the alias name.
Fixes#6334.
While working on the gateway→_gateway conversion, I noticed that
libidn2 strips the leading underscore in some names.
https://gitlab.com/libidn/libidn2/issues/30 was resolved in
05d753ea69,
which disabled "STD3 ASCII rules" by default, i.e. disabled stripping
of underscores. So the situation is that with previously released libidn2
versions we would get incorrect behaviour, and once new libidn2 is released,
we should be OK.
Let's implement a simple test which checks that the name survives the
roundtrip, and if it doesn't, skip IDN resolution. Under old libidn2 this will
fail in more cases, and under new libidn2 in fewer, but should be the right
thing to do also under new libidn2.
As a follow-up for db3f45e2d2 let's do the
same for all other cases where we create a FILE* with local scope and
know that no other threads hence can have access to it.
For most cases this shouldn't change much really, but this should speed
dbus introspection and calender time formatting up a bit.
Given that we set NOTIFY_SOCKET unconditionally it's not surprising that
processes way down the process tree think it's smart to send us a
notification message.
It's still useful to keep this message, for debugging things, but it
shouldn't be generated by default.
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.
In case fstab-generator is called in the initrd, chase_symlinks()
returns with a canonical path "/sysroot/sysroot/<mountpoint>", if the
"/sysroot" prefix is present in the path.
This patch skips the "/sysroot" prefix for the chase_symlinks() call,
because "/sysroot" is already the root directory and chase_symlinks()
prepends the root directory in the canonical path returned.
This adds support for the mkosi switch --without-tests that is
introduced by:
https://github.com/systemd/mkosi/pull/122
With this in place doing "mkosi -ifT shell" is the fastest way from a
git clone to a shell within a freshly compiled systemd system.
QEMU >= 2.10 will include a CPUID leaf with value "TCGTCGTCGTCG"
on x86 when running with the TCG CPU emulator:
https://lists.gnu.org/archive/html/qemu-devel/2017-07/msg05231.html
Existing methods of detecting QEMU are left unchanged for sake of
backcompatibility.

Since 3536f49e8f, manager_new() in
user mode requires XDG_RUNTIME_DIR is set. So, in this commit,
setup_fake_runtime_directory() is added in the beginning of test.
Fixes an issue comment in #6384.
This makes it more like other configure defines.
Also, it fixes meson status output which was looking for HAVE_ and ENABLE_
prefixes only (the define under meson was OK, just the summary message was
wrong.)
This adds the basic make support required by
https://github.com/cgwalters/build-api. CFLAGS, CXXFLAGS, DESTDIR variables are
supported:
./configure CFLAGS=... CXXFLAGS=... && make && make install DESTDIR=
Automatic rebuilding is removed: it doesn't play well with ninja, because
ninja always writes logs, and even if nothing needs to be built, it will
make the log file owned by root. So let's just remove this, and say that
the user must always do the build first.
I'm also keeping make for the tests, because ninja doesn't play well with
sudo.
Since the build directory is arbitrary, it needs to be specified, e.g.
sudo make BUILD_DIR=/home/zbyszek/src/systemd/build1 -C test/TEST-01-BASIC/
This introduces {State,Cache,Log,Configuration}Directory= those are
similar to RuntimeDirectory=. They create the directories under
/var/lib, /var/cache/, /var/log, or /etc, respectively, with the mode
specified in {State,Cache,Log,Configuration}DirectoryMode=.
This also fixes#6391.
In networkd-test.py, don't assert that the router state is "routable".
While it should eventually become that, we don't wait for it, and thus
at that point it often is "carrier" or "degrated" still. It is also not
really relevant as this only tests the "client" side interface.
Trivial performance boost by explicitly bypassing the implicit
locking of stdio.
This significantly affects common cases of `journalctl` usage:
Before:
# time ./journalctl -b -1 > /dev/null
real 0m26.628s
user 0m26.495s
sys 0m0.125s
# time ./journalctl -b -1 > /dev/null
real 0m27.069s
user 0m26.936s
sys 0m0.134s
# time ./journalctl -b -1 > /dev/null
real 0m26.727s
user 0m26.607s
sys 0m0.119s
After:
# time ./journalctl -b -1 > /dev/null
real 0m23.394s
user 0m23.244s
sys 0m0.142s
# time ./journalctl -b -1 > /dev/null
real 0m23.283s
user 0m23.160s
sys 0m0.121s
# time ./journalctl -b -1 > /dev/null
real 0m23.274s
user 0m23.125s
sys 0m0.144s
