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.
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.
This test doesn't require the tests to be installed, so it must manually
install required test services and targets itself, including the default
target of testsuite.target
Also use $TEST_UNITS_DIR which is set by test-functions instead of
calculating the path
The $BUILD_DIR is only used in test-functions, and doesn't need to
be specified in any other scripts. Additionally, to be able to allow
the integration test suite to be run against locally installed binaries,
instead of built binaries, moving BUILD_DIR logic completely into
test-functions allows later patches to be simpler.
Building custom images for each test takes a lot of time.
Build the default one, and if the test needs incompatible changes
just copy it and extend it instead.
has-overflow was a temporary hack that was removed in
844da987ef (Oct. 2016). All the makefiles
can be the same, and all the targets can be handled identically.
Before, we'd create a separate image for each test, in
/var/tmp/systemd-test.XXXXX/rootdisk.img. Most of the images
where very similar, except that each one had some unit files installed
specifically for the test. The installation of those custom unit files
was removed in previous commits (all the unit files are always installed).
The new approach is to only create as few distinct images as possible.
We have:
default.img: the "normal" image suitable for almost all the tests
basic.img: the same as default image but doesn't mask any services
cryptsetup.img: p2 is used for encrypted /var
badid.img: /etc/machine-id is overwritten with stuff
selinux.img: with selinux added for fun and fun
and a few others:
ls -l build/test/*img
lrwxrwxrwx 1 root root 38 Mar 21 21:23 build/test/badid.img -> /var/tmp/systemd-test.PJFFeo/badid.img
lrwxrwxrwx 1 root root 38 Mar 21 21:17 build/test/basic.img -> /var/tmp/systemd-test.na0xOI/basic.img
lrwxrwxrwx 1 root root 43 Mar 21 21:18 build/test/cryptsetup.img -> /var/tmp/systemd-test.Tzjv06/cryptsetup.img
lrwxrwxrwx 1 root root 40 Mar 21 21:19 build/test/default.img -> /var/tmp/systemd-test.EscAsS/default.img
lrwxrwxrwx 1 root root 39 Mar 21 21:22 build/test/nspawn.img -> /var/tmp/systemd-test.HSebKo/nspawn.img
lrwxrwxrwx 1 root root 40 Mar 21 21:20 build/test/selinux.img -> /var/tmp/systemd-test.daBjbx/selinux.img
lrwxrwxrwx 1 root root 39 Mar 21 21:21 build/test/test08.img -> /var/tmp/systemd-test.OgnN8Z/test08.img
I considered trying to use the same image everywhere. It would probably be
possible, but it would be very brittle. By using separate images where it is
necessary we keep various orthogonal modifications independent.
The way that images are cached is complicated by the fact that we still
want to keep them in /var/tmp. Thus, an image is created on first use and
linked to from build/test/ so it can be found by other tests.
Tests cannot be run in parallel. I think that is an acceptable limitation.
Creation of the images was probably taking more resources then the actual
tests, so we should be better off anyway.
As in 2a5fcfae02
and in 3e67e5c992
using /usr/bin/env allows bash to be looked up in PATH
rather than being hard-coded.
As with the previous changes the same arguments apply
- distributions have scripts to rewrite shebangs on installation and
they know what locations to rely on.
- For tests/compilation we should rather rely on the user to have setup
there PATH correctly.
In particular this makes testing from git easier on NixOS where do not provide
/bin/bash to improve compose-ability.
Almost all tests were manually mounting/unmounting $TESTDIR/root
from the loopback image; this moves all that into test-functions
so the test setup functions are simplier.
Also add test_setup_cleanup() function, to cleanup what is mounted
by create_empty_image_rootdir()
The `set -e` option is incompatible with a subshell/compound command,
which is followed by || <EXPR>. In such case, the -e option is ignored
in all affected subshells/functions (see man bash(1) for command `set`).
In certain situations, the systemctl commands may fail (e.g. due to
missing shared libraries), but the 'script' continues and creates a
/testok file, marking the test incorrectly as passed. Let's fix this and
bail out immediately when a command exits with a non-zero exit code.
We had all kinds of indentation: 2 sp, 3 sp, 4 sp, 8 sp, and mixed.
4 sp was the most common, in particular the majority of scripts under test/
used that. Let's standarize on 4 sp, because many commandlines are long and
there's a lot of nesting, and with 8sp indentation less stuff fits. 4 sp
also seems to be the default indentation, so this will make it less likely
that people will mess up if they don't load the editor config. (I think people
often use vi, and vi has no support to load project-wide configuration
automatically. We distribute a .vimrc file, but it is not loaded by default,
and even the instructions in it seem to discourage its use for security
reasons.)
Also remove the few vim config lines that were left. We should either have them
on all files, or none.
Also remove some strange stuff like '#!/bin/env bash', yikes.
Currently, if I run the full "run-integration-tests.sh" script it will
fail on my machine because it fills up /var/tmp whith just too much
crap until the disk is full.
Let's make sure that "run-integration-tests.sh" cleans up after every
test. For that change the make targets to run from "clean setup run" to
"clean setup run clean" — except that that doesn't work since make is
smart enough to realize that the same target appears twice on the
command line and will only execute it once. Let's fix that by defining
another target "clean-again" which is just like "clean", but allows us
to be added to the same command line a second time. Then, let's build
with "clean setup run clean-again" and all is good.
While we are at it, let's also add .PHONY where appropriate, after all
these all are phony targets.
Ignore mkosi.builddir. In the future we can also add other patterns
if necessary.
run-intergration-tests.sh is updated to use the new script, and modified
to work from arbitrary directory.
Follow-up for #7494.
This catches errors like "ninja not found", missing programs etc. early,
instead of silently ignoring them and trying to boot a broken VM.
In install_config_files(), allow some distro specific files to be absent
(such as /etc/sysconfig/init).
All test/TEST* but TEST-02-CRYPTSETUP share the same check_result_qemu()
and test_cleanup(), so move them into test_functions and only override
them in TEST-02-CRYPTSETUP.
Also provide a common test_run() which by default assumes that both QEMU
and nspawn tests are run. Particular tests which don't support either
need to explicitly opt out by setting $TEST_NO_{QEMU,NSPAWN}. Do it this
way around to avoid accidentally forgetting to opt in, and to encourage
test authors to at least always support nspawn.
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/
* remove journal flushing (systemd-journal-flush.service runs journalctl --flush on boot)
* use sh -c and PATH instead of @SYSTEMCTL@ expansion
* remove unnecessary semicolons etc
It tries to find a suitable QEMU binary and will use KVM if present.
We can now configure QEMU from outside with 4 variables :
- $QEMU_BIN : path to QEMU's binary
- $KERNEL_APPEND : arguments appended to kernel cmdline
- $KERNEL_BIN : path to a kernel
Default /boot/vmlinuz-$KERNEL_VER
- $INITRD : path to an initramfs
Default /boot/initramfs-${KERNEL_VER}.img
- $QEMU_SMP : number of CPU simulated by QEMU.
Default 1
(from Alexander Graf's script: http://www.spinics.net/lists/kvm/msg72389.html)
- fix typo
- use compiled systemd-nspawn
- drop --capability=... from systemd-nspawn invocation, is is the default now
- simplify sudo make invocations
Tests can use the same testsuite.target.
Add end.service to call poweroff instead of doing it from ExecStopPost
where it may be skipped on failure of ExecStart.
