NO_BUILD=1 indicates that we want to test systemd from the local system and not
the one from the local build. Hence there should be no need to call
find-build-dir.sh when NO_BUID=1 especially since it's likely that the script
will fail to find a local build in this case.
This avoids find-build-dir.sh to emit 'Specify build directory with $BUILD_DIR'
message when NO_BUILD=1 and no local build can be found.
This introduces a behavior change though: systemd from the local system will
always be preferred when NO_BUILD=1 even if a local build can be found.
In some cases image names are unpredictable - some orchestrators/deployment
tools like to mangle names to suit their internal formats. In these cases,
the requirement that the extension-release file matches exactly the image
name where it's contained cannot work.
Allow falling back to loading the first regular file which name starts with
'extension-release' located in /usr/lib/extension-release.d/ and tagged with
a user.extension-release.strict extended attribute with a true value, if the
one with the expected name cannot be found.
Skip a harmless error when running the tests on a system with a significantly
older systemd version (ldd tries to resolve the unprefixed RPATH for libsystemd.so.0,
which is in this case older than the already installed libsystemd.so.0 in $initdir).
The issue is triggered by installing test dependencies in install_missing_libraries().
Spotted on CentOS 8.

When `linux-headers` is installed on Arch Linux, it stores the module
source tree in the kernel module directory, which is then picked up by
`find` and we get a lot of harmless but annoying errors:
```
...
modprobe: FATAL: Module Kconfig.iosched not found in directory /lib/modules/5.13.7-arch1-1
modprobe: FATAL: Module Kconfig not found in directory /lib/modules/5.13.7-arch1-1

...
```
Let's fix this by trying to install only kernel modules (*.ko files with
an optional compression).
Let's unify handling of the boolean values throughout the test-functions
code, since we use 0/1, true/false, and yes/no almost randomly in many
places, so picking the right values during CI configuration can be a real
pain.
Saving the journal for passing tests creates a huge amount of unneeded
data stored for each full test run. Add a env var to allow saving the
journal only for failed tests.
Due to a little misunderstanding the last patch doesn't work as
expected, since test_create_image() is called only for the first image
(usually TEST-01-BASIC), and all subsequent images are then (possibly)
modified with test_append_files().
Follow-up to 179ca4d2b1.
It turns out the "supporting services" were run in _all_ tests if
TEST-01-BASIC was run as the first test (which is usually the case),
since with the original condition in test_create_image() we would skip
the masking and then propagate the change to the default image used by
other tests. This has been causing multiple bogus test timeouts
(especially when the hwdb was being rebuilt in tests with short
timeouts, like TEST-52-HONORFIRSTSHUTDOWN).
Let's "fix" this by making the call to mask_supporting_services()
uncoditional and override the test_create_image() function in
TEST-01-BASIC to avoid the masking in this single case.
The three-argument match() is a GNU AWK extension, thus breaking the
compatibility with mawk (used on Ubuntu/Debian, for example). Let's
replace it with a (hopefully) more portable sed expression to drop the
inadvertently introduced gawk dependency.
Fixes: #19957
This fixes an issue introduced by the commit 954c77c251.
For some reasons, setting default ACL on $TESTDIR makes TEST-29-PORTABLE
fail. Let's drop the default ACL, and set ACL on saved results instead.
Fixes#19519.
"systemd-testsuite" gets in the way when grepping for "testsuite-*.sh".
Also, the name doesn't matter for anything, so let's just use something
very short to save space.
When editing this function in 7bf20e48bd, I couldn't
decide whether to initialize ret at the top and only reset it on success, or
whether to assign a value in each branch. In the end I did neither ;( So if the
test finished without creating any of the result files, we would echo a
message, but return "success".
But there was bigger confusion with /failed: some tests create it empty, some
don't. I think we may want to do away pre-creation of /failed completely, and
assume the test failed unless /testok is found. But I'm leaving that for later
rework. For now let's just make sure we report return success only if /testok
or /skipped is found.
Basically the same scenario as in
a33e2692e1, where `awk` exits as soon
as it finds a match, thus sending SIGPIPE to `ldd` if it's not fast
enough. That, in combination with `set -o pipefail` causes random &
unexpected fails, like:
```
No journal files were found.
-rw-r----- 1 root root 16777216 Apr 30 10:31
/var/tmp/TEST-01-BASIC_sanitizers-nspawn/system.journal
TEST-01-BASIC RUN: Basic systemd setup [OK]
systemd is not linked against the ASan DSO
gcc does this by default, for clang compile with -shared-libasan
make: *** [Makefile:2: clean-again] Error 1
make: Leaving directory '/build/test/TEST-01-BASIC'
```
Specifying the test number manually is tedious and prone to errors (as
recently proven). Since we have all the necessary data to work out the
test number, let's do it automagically.
We have to invoke the tests as superuser, and not being able to read
the journal as the invoking user is annoying. I don't think there are
any security considerations here, since the invoking user can already
put arbitrary code in the Makefile and test scripts which get executed
with root privileges.
The logic to query test state was rather complex. I don't quite grok the point
of ret=$((ret+1))… But afaics, the precise result was always ignored by the
caller anyway.
This code was partially broken, since the firmware directory was
undefined. Also, some of the parts were a dead code, since they relied
on code from the original dracut test suite.
`command -v <bin> | grep ...` can under certain conditions cause the
`command` to exit with SIGPIPE, which in combination with `set -o
pipefail` means that the tests sometimes randomly die during setup.
Let's avoid using pipes in such cases.
This breaks some existing loops which previously ignored if the piped
program exited with EC >0. Rewrite them to mitigate this (and also make
them more robust in some cases).
When trying to calculate the next firing of 'Sun *-*-* 01:00:00', we'd fall
into an infinite loop, because mktime() moves us "backwards":
Before this patch:
tm_within_bounds: good=0 2021-03-29 01:00:00 → 2021-03-29 00:00:00
tm_within_bounds: good=0 2021-03-29 01:00:00 → 2021-03-29 00:00:00
tm_within_bounds: good=0 2021-03-29 01:00:00 → 2021-03-29 00:00:00
...
We rely on mktime() normalizing the time. The man page does not say that it'll
move the time forward, but our algorithm relies on this. So let's catch this
case explicitly.
With this patch:
