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.
Last month I monkey-patched journald to produce a small (64K) but valid
journal and used that as an input to four AFL fuzzers. After a month it
generated quite a nice corpora (4738 test cases) and after filtering
and minimizing it I was left with 619 unique journals with various
levels of corruption that probe the journal code.
It seems to detect past issues like systemd#26567, etc.
As the systemd-pstore process is quite short lived, it might sometimes
lack the necessary metadata to make matching against a unit or a syslog
tag work. Since we already use a cursor file to make the matching window
small as possible, let's just drop the unit match completely and hope
for the best.
Resolves: #27453
As described in systemd/systemd#27204 reexecuting the daemon while
running in a systemd-run "session" causes the session end prematurely.
Let's skip the Reexecute() method in dfuzzer and trigger it manually
until the issue is resolved.
When doing a conversion and the specified 'xc->xvariant' has no match, select
the x11 layout entry with a matching layout and an empty xvariant if such entry
exists. It's still better than no conversion at all.
