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.
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.
When running TEST-22 under ASan, there's a chain of events which causes
`stat` to output an extraneous ASan error message, causing following
fail:
```
+ test -d /tmp/d/1
++ stat -c %U:%G:%a /tmp/d/1
==82==ASan runtime does not come first in initial library list; you should either link runtime to your application or manually preload it with LD_PRELOAD.
+ test = daemon:daemon:755
.//usr/lib/systemd/tests/testdata/units/testsuite-22.02.sh: line 24: test: =: unary operator expected
```
This is caused by `stat` calling nss which in Arch's configuration calls
the nss-systemd module, that pulls in libasan which causes the $LD_PRELOAD
error message, since `stat` is an uninstrumented binary.
The $LD_PRELOAD variable is explicitly unset for all testsuite-* services
since it causes various issues when calling uninstrumented libraries, so
setting it globally is not an option. Another option would be to set
$LD_PRELOAD for each `stat` call, but that would unnecessarily clutter
the test code.
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.
This sould make our test suite a bit more robust if it is slow running.
A few of our test services use StandardOutput=tty or StandardError=tty
in the tests in order to connect test services to the container console.
This gets into conflict with the container getty which wants exclusive
access to the console. Since the container getty is started with
Type=idle it typically gets started after a timeout only if the TTY is
already used, which hence introduces a race: if the test finishes
earlier all is good, if not, then the test gets kicked off the TTY which
then causes bash to abort since it cannot write any error messages
anymore.
Let's fix this hence: all tests that connect to the tty are now
synchronized to getty-pre.target, so they finish before any getty is
started.
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.
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.
A follow-up for commit 9d874aec45.
This patch makes "path" parameter mandatory in fd_set_*() helpers removing the
need to use fd_get_path() when NULL was passed. The caller is supposed to pass
the fd anyway so assuming that it also knows the path should be safe.
Actually, the only case where this was useful (or used) was when we were
walking through directory trees (in item_do()). But even in those cases the
paths could be constructed trivially, which is still better than relying on
fd_get_path() (which is an ugly API).
A very succinct test case is also added for 'z/Z' operators so the code dealing
with recursive operators is tested minimally.
Yes, the output is sometimes annyoing, but /dev/null is not the right
place...
I figure this redirection was left in from some debugging session, let's
fix it, and make the setup_basic_environment invocation like in all
other test scripts.
