The check_loaded() function compares the zone's loadtime value and
an expected loadtime value, which is based on the zone file's mtime
extracted from the filesystem.
For the secondary zones there may be cases, when the zone file isn't
ready yet before the zone transfer is complete and the zone file is
dumped to the disk, so a so zero value mtime is retrieved.
In such cases wait one second and retry until timeout. Also modify
the affected check to allow a possible difference of the same amount
of seconds as the chosen timeout value.
when transferring in a non-inline-signing secondary for the first time,
we previously never set the value of zone->loadtime, so it remained
zero. this caused a test failure in the statschannel system test,
and that test case was temporarily disabled. the value is now set
correctly and the test case has been reinstated.
It is better to disable the specific check that causes the test to fail
rather than mark the entire test as xfail, which can mask other issues
which the test is capable of detecting.
The "statschannel" system test contains two Python helper modules:
- generic.py: test functions directly invoked by both tests-json.py
and test-xml.py,
- helper.py: helper functions invoked by test functions in generic.py.
The above logic for splitting helper functions into Python modules
prevents selective test skipping from working due to unconditional
import statements being present in both helper modules. For example, if
dnspython is not available on the test host, tests-json.py imports
generic.py, which in turn imports helper.py, which in turn attempts to
import various dnspython modules, triggering ImportError exceptions
during test initialization. Various decorators used for some tests
(like @pytest.mark.dnspython) suggest that such a scenario should be
handled gracefully, but that is not the case - modifying the test
collection in conftest.py does not prevent pytest from failing due to
import errors.
Fix by moving helper functions around to achieve a different split:
- generic.py: helper functions only relying on the Python standard
library,
- generic_dnspython.py: helper functions requiring dnspython.
Only two tests in tests-{json,xml}.py need dnspython to work
(test_traffic_json(), test_traffic_xml()). Since all
dnspython-dependent code is now present in generic_dnspython.py, employ
pytest.importorskip() in those two tests to ensure they can be
selectively skipped when dnspython is not available. Adjust other code
to account for the revised Python helper module layout. Remove all
occurrences of the @pytest.mark.dnspython decorator (and all associated
code) from the "statschannel" system test to prevent confusion.
This commit converts the license handling to adhere to the REUSE
specification. It specifically:
1. Adds used licnses to LICENSES/ directory
2. Add "isc" template for adding the copyright boilerplate
3. Changes all source files to include copyright and SPDX license
header, this includes all the C sources, documentation, zone files,
configuration files. There are notes in the doc/dev/copyrights file
on how to add correct headers to the new files.
4. Handle the rest that can't be modified via .reuse/dep5 file. The
binary (or otherwise unmodifiable) files could have license places
next to them in <foo>.license file, but this would lead to cluttered
repository and most of the files handled in the .reuse/dep5 file are
system test files.
