The systemd-cryptenroll man page states:
Takes a comma separated list of numeric slot indexes, or the special
strings ..., or any combination of these strings or numeric
indexes, in which case all slots matching either are wiped.
but we'd allow only one special string at any given time as the value
was not ORed when assigning. So, for example, --wipe=recovery,password
would actually become --wipe=password, etc.
Until now, we always excluded the top level directories that were
covered by child partition mount points, regardless of the source
directory and the target directory of the copy files operation.
This means that even if we were populating a XBOOTLDR partition, if
there was an EFI partition in the image, we'd exclude /boot
unconditionally, leading to the XBOOTLDR partition to be empty.
Also, because of the same cause, if we were copying a nested source
directory (e.g. /abc/def) to the root directory in the root
partition, if /abc/def/usr existed and was populated with files and
directories, the root partition would have those files under /usr,
even if a /usr partition was defined.
To fix these issues, instead of unconditionally excluding the top
level partition mount points under <source>, let's make sure that
when we're copying files from any source directory to the root
directory of a root partition, that we exclude the partition mount
point directories under the source directory instead of the top
level ones.
Rename TEST-23-TYPE-EXEC to TEST-23-UNIT-FILE and merge it with
following tests:
- TEST-37-RUNTIMEDIRECTORYPRESERV
- TEST-40-EXEC-COMMAND-EX
- TEST-41-ONESHOT-RESTART
- TEST-42-EXECSTOPPOST
- TEST-57-ONSUCCESS-UPHOLD
This gets rid of the all-but-one remaining uses of perl. I tested the new code
on my machine, so I'm fairly confident that it works as expected.
install_iscsi() has one majestic perl invocation, but we can't get rid of it
easily: it extends the code of tgt-admin to print some list of files. Obviously
this only works because tgt-admin is written in perl, and perl will be installed
if tgt-admin is installed. install_iscsi() is used in TEST-64-UDEV-STORAGE
conditionally if tgtadm is installed, so this can stay as is.
When the interpeter is missing, we get an exit code of 127. Let's treat those
tests as skipped too. If we could run the test far enough so that it could do
the check itself, it would return 77 anyway.
$ test/asdf; echo $?
exec: Failed to execute process 'test/asdf': The file specified the interpreter '/bin/asdf', which is not an executable command.
127
$ test/asdf; echo $?
/usr/bin/env: ‘/bin/asdf’: No such file or directory
127
This should resolve the problem that TEST-02 fails or Debian's 'unit-tests' fail
when python3 is not installed. Installing python3 via the mechanism that is
used to construct TEST images, i.e. the dracut dependency chasing scheme, would
be a lot of work for python with its modules in multiple locations and hundreds
of little files. So I think it OK to just skip the test there, and also in
other cases where python is not available.
As part of the build, we would populate build/test/sys/ using
sys-script.py, and then udev-test.p[ly] would create a tmpfs instance
on build/test/tmpfs and copy the sys tree to build/test/tmpfs/sys.
Also, we had udev-test.p[ly] which called test-udev. test-udev was
marked as a manual test and installed, but neither udev-test.p[ly] or
sys-script.py were.
test-udev is renamed to udev-rule-runner, which reduces confusion and
frees up the test-udev name. udev-test.py is renamed to test-udev.py.
All three files are now installed.
test-udev.py is modified to internally call sys-script.py to set up the
sys tree. Copying and creating it from scratch should take the same
amount of time. We avoid having a magic directory, everything is now
done underneath a temporary directory.
test-udev.py is now a normal installed test, and run-unit-tests.py will
pick it up. When test-udev.py is invoked from meson, the path to
udev-rule-runner is passed via envvar; when it is invoked via
run-unit-tests.py or directly, it looks for udev-rule-runner in a relative
path.
The goal of this whole change is to let Debian drop the 'udev' test.
It called sys-script.py and udev-test.pl from the source directory and
had to recreate a bunch of the logic. Now test-udev.py will now be called
via 'upstream'.
I tried to keep this a 1:1 rewrite with the same field names.
Nevertheless, some changes were made:
- exp_add_error and exp_rem_error are dropped. Those fields meant that
"./test-udev add <devpath>" actually succeeded, but symlinks were not
created, and exp_links was ignored and could contain bogus content.
Instead, exp_links and not_exp_links are adjusted to not contain
garbage and the tests check that "./test-udev add" succeeds and that
the links are as expected from exp_links and not_exp_links.
- cleanup was only used in one rule, and that rule was expected to fail,
so cleanup wasn't actually necessary. So the cleanup field and the
logic to call cleanup from individual tests is removed.
- a bunch of fields were set, but didn't seem to be connected to any
implementation: not_exp_name, not_exp_test.
e62acc3159 did a rewrite of some of the
tests and it seems that not_exp_test was added by mistake and
not_exp_name was left behind by mistake.
In Python, the field list is declared in the class, so it's harder to
assign an unused attribute. Those uses were converted to not_exp_links.
- in most rules, r"""…""" is used, so that escaping is not necessary.
- the logic to generate devices was only used in one place, and the
generator function also had provisions to handle arguments that were
never given. all_block_devs() is made much simpler.
- Descriptions that started with a capital letter were shortened
and lowercased.
- no special test case counting is done. pytest just counts the cases
(Rules objects).
- the output for failures is also removed. If something goes wrong, the
user can use pytest --pdb or such to debug the issue.
- perl version used a semaphore to manage udev runners, and would fork,
optionally wait a bit, and then start the runner. In the python
version, we just spawn them all and wait for them to exit. It's not
very convenient to call fork() from python, so instead the runner
was modified (in previous commit) to wait.
The test can be called as:
(cd build && sudo pytest -v ../test/udev-test.py)
sudo meson test -C build udev-test.py -v
I think this generally provides functionality that is close to the perl
version. It seems some of the checks are now more fully implemented.
Support for strace/gdb/valgrind is missing.
Runtime goes down: 8.36 s → 5.78 s.
