MIPS/O32's st_rdev member of struct stat is unsigned long, which
is 32bit, while dev_t is defined as 64bit, which make some problems
in device_path_parse_major_minor.
Don't pass st.st_rdev, st_mode to device_path_parse_major_minor,
while pass 2 seperate variables. The result of stat is alos copied
out into these 2 variables. Fixes: #11247
The test fails under valgrind, so there was an exception for valgrind.
Unfortunately that check only works when valgrind-devel headers are
available during build. But it is possible to have just valgrind installed,
or simply install it after the build, and then "valgrind test-json" would
fail.
It also seems that even without valgrind, this fails on some arm32 CPUs.
Let's do the usual-style test for absolute and relative differences.
Nitpicky, but we've used a lot of random spacings and names in the past,
but we're trying to be completely consistent on "cgroup vN" now.
Generated by `fd -0 | xargs -0 -n1 sed -ri --follow-symlinks 's/cgroups? ?v?([0-9])/cgroup v\1/gI'`.
I manually ignored places where it's not appropriate to replace (eg.
"cgroup2" fstype and in src/shared/linux).
As devpath may not be set yet.
When debug logging is enabled, log_device_*() calls
sd_device_get_sysname(). So, we should not assume that devpath is always
set.
Fixes#11258.
The current support in kernel-install for initrd images doesn't copy
over the initrd file or allow a means for it to be specified (it
requires a specific filename in a particular directory).
This patchset adds support for (optionally) providing the name of
initial ramdisk file to copied over and used by kernel-install.
"src/basic/time-util.c" is part of src/basic and should not include
"src/shared/serialize.h". It is one of the few cases where this
is done. Also, it's not even required.
Commit 250e9fadbc introduced
support for %j/%J specifier in unit files. The function
unit_name_printf is used in unit dependency resolution,
such as Wants / After directives, but was missing support
for the %j. Add to allow directives such as:
[Unit]
Wants=bar-%j.target

Continuation of a3ebe5eb62:
in other places we sometimes use assert_se(), and sometimes normal error
handling. sigfillset and sigaddset can only fail if mask is NULL (which cannot
happen if we are passing in a reference), or if the signal number is invalid
(which really shouldn't happen when we are using a constant like SIGCHLD. If
SIGCHLD is invalid, we have a bigger problem). So let's simplify things and
always use assert_se() in those cases.
In sigset_add_many() we could conceivably pass an invalid signal, so let's keep
normal error handling here. The caller can do assert_se() around the
sigprocmask_many() call if appropriate.
'>= 0' is used for consistency with the rest of the codebase.
This reverts commit edda44605f.
The kernel explicitly supports resuming with a different kernel than the one
used before hibernation. If this is something that shouldn't be supported, the
place to change this is in the kernel. We shouldn't censor something that this
exclusively in the kernel's domain.
People might be using this to switch kernels without restaring programs, and
we'd break this functionality for them.
Also, even if resuming with a different kernel was a bad idea, we don't really
prevent that with this check, since most users have more than one kernel and
can freely pick a different one from the menu. So this only affected the corner
case where the kernel has been removed, but there is no reason to single it
out.
All underlying glibc calls are free to return NULL if the size argument
is 0. We most often call those functions with a fixed argument, or at least
something which obviously cannot be zero, but it's too easy to forget.
E.g. coverity complains about "rows = new0(JsonVariant*, n_rows-1);" in
format-table.c There is an assert that n_rows > 0, so we could hit this
corner case here. Let's simplify callers and make those functions "safe".
CID #1397035.
The compiler is mostly able to optimize this away:

cgroup_no_v1=all doesn't make a whole lot of sense with legacy hierarchy
(where we use v1 hierarchy for everything), or hybrid hierarchy (where
we still use v1 hierarchy for resource control).
Right now we have to tell people to add both cgroup_no_v1=all and
systemd.unified_cgroup_hierarchy=1 to get the desired behaviour,
however in reality it's hard to imagine any situation where someone
passes cgroup_no_v1=all but *doesn't* want to use the unified cgroup
hierarchy.
Make it so that cgroup_no_v1=all produces intuitive behaviour in systemd
by default, although it can still be disabled by passing
systemd.unified_cgroup_hierarchy=0 explicitly.
The idea was that those vars could be configured to 'no' to not install the .pc
files, or they could be set to '', and then they would be built but not
installed. This was inherited from the autoconf build system. This couldn't
work because '' is replaced by the default value. Also, having this level of
control doesn't seem necessary, since creating those files is very
quick. Skipping with 'no' was implemented only for systemd.pc and not the other
.pc files. Let's simplify things and skip installation if the target dir
is configured as 'no' for all .pc files.

This is very useful during development, because a precise version string is
embedded in the build product and displayed during boot, so we don't have to
guess answers for questions like "did I just boot the latest version or the one
from before?".
This change creates an overhead for "noop" builds. On my laptop, 'ninja -C
build' that does nothing goes from 0.1 to 0.5 s. It would be nice to avoid
this, but I think that <1 s is still acceptable.
Fixes#7183.
PACKAGE_VERSION is renamed to GIT_VERSION, to make it obvious that this is the
more dynamically changing version string.
Why save to a file? It would be easy to generate the version tag using
run_command(), but we want to go through a file so that stuff gets rebuilt when
this file changes. If we just defined an variable in meson, ninja wouldn't know
it needs to rebuild things.
PROJECT_VERSION is used in preparation for future changes. Let's simplify the
code by using structured initialization. If the string written to .version ever
became to long, the compiler will truncate it and tell us:
../src/udev/udev-ctrl.c: In function ‘ctrl_send’:
../src/udev/udev-ctrl.c:221:28: warning: initializer-string for array of chars is too long
.version = "udev-" STRINGIFY(R_VERSION),
^~~~~~~
../src/udev/udev-ctrl.c:221:28: note: (near initialization for ‘ctrl_msg_wire.version’)
No functional change.
