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.
Many tests were also masking systemd-machined.service. But machined
should only start when activated, so having it not masked shouldn't be
noticable. TEST-25-IMPORT needs it.
I *think* this was originally added to make it easier to see what was happening
in tests. Later we added the functionality to print the journal on failure, so
this redirection has stopped being useful.
In https://github.com/systemd/systemd/pull/13719#issuecomment-539292650
@filbranden shows that grep tries to write to stdout and fails. In general,
we should not assume that writing to the console it always possible. We have
special code to handle this in pid1 after all:
99 19:22:10.731965 fstat(1, <unfinished ...>
99 19:22:10.731993 <... fstat resumed>{st_mode=S_IFCHR|0620, st_rdev=makedev(0x88, 0), ...}) = 0
99 19:22:10.732070 write(1, "ExecStartPost={ path=/bin/echo ; argv[]=/bin/echo ${4_four_ex} ; ignore_errors=no ; start_time=[Mon 2019-10-07 19:22:10 PDT] ; stop_time=[Mon 209-10-07 19:22:10 PDT] ; pid=97 ; code=exited ; status=0 }\n", 203) = -1 EIO (Input/output error)
99 19:22:10.732174 write(2, "grep: ", 6) = -1 EIO (Input/output error)
99 19:22:10.732226 write(2, "write error", 11) = -1 EIO (Input/output error)
99 19:22:10.732263 write(2, ": Input/output error", 20) = -1 EIO (Input/output error)
99 19:22:10.732298 write(2, "\n", 1 <unfinished ...>
99 19:22:10.732325 <... write resumed>) = -1 EIO (Input/output error)
99 19:22:10.732349 exit_group(2) = ?
99 19:22:10.732424 +++ exited with 2 +++
Removing the redirection should make the tests less flakey.
Replaces #13719.
While at it, also drop NotifyAccess=all. I think it was added purposefully in
TEST-20-MAINPIDGAMES, and then cargo culted to newer tests.
We should never have used an unprefixed environment variable name.
All other systemd-nspawn variables have the "SYSTEMD_NSPAWN_" prefix,
and all other systemd variables have the "SYSTEMD_" prefix.
The new variable name takes precedence, but we fall back to checking the
old one. If only the old one is found, a warning is emitted.
In addition, SYSTEMD_NSPAWN_UNIFIED_HIERARCHY="" is accepted as an override
to avoid looking for the old variable name.
We have a variable with the same name ($UNIFIED_CGROUP_HIERARCHY) in tests,
which governs both systemd-nspawn and qemu behaviour. It is not renamed.
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`).
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.
Not all distros support booting without an initrd. E.g. the Debian
kernel builds ext4 as a module and so relies on an initrd to
successfully start the QEMU-based images.
We need to specify a full path to the "ip" binary and busybox "ip" has a
slightly different output than the normal ip, and won't show "DOWN".
hence instead ensure that at lest not "UP" is in there.
Since the new option `--network-namespace-path=` of systemd-nspawn
cannot be used together with other network-related options, we need
to add more smoke tests for checking these conditions of options.
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.
