Not every element tagged `skipped` in the JUnitXML tree has to contain
the `type` attribute. An example of that is a test that results in
xpass.
This has been verified with pytest version 7.4.2 and prior.
Add a GitLab CI job that is only run for tags and makes signing BIND 9
releases more convenient by utilizing a signing VM that is registered as
a GitLab CI runner. This pulls the signing process into the release
pipelines in GitLab CI, resulting in job artifacts containing the
signatures for BIND 9 releases, which in turns simplifies the subsequent
release publication steps.
EXPERIMENT: when DNS_DB_GLUEOK is set, dns_view_find() will now return
glue if it is found it a local zone database, without checking to see
if a better answer has been cached previously.
If a child zone is served by the same servers as a parent zone and
a NS query is made for the zone name then the addresses of the
nameservers are returned in the additional section are tagged as
trust additional.
Commit 4db150437e14b28c5b50ae466af9ce502fd73185 incorrectly removed the
call to isc_mem_setwater() from dns_cache_setcachesize(). The water()
function is a no-op, but we still need to set high- and low-water marks
in the memory context, otherwise overmem conditions will not be
detected.
Run comparative performance tests against the latest released version of
the same branch. This is done for different protocols with an
appropriate load the server is expected to be able to handle.
Currently, the results need to be inspected manually, since a success of
the job doesn't indicate there is no issue. Instead, the job provides an
URL to an overview with latency, memory and CPU charts which display the
test results with the current code against the reference version. There
should be no major unexplained and reproducible differences in the
charts.
The shotgun performance tests are executed in a different repository, in
a couple of different pipelines. To hide away the complexity, this
script takes the pipeline ID of the triggered pipeline and then takes
care of the rest - waits for the pipeline to finish, locates the child
pipeline and the relevant results. The output from this script is a
convenient link to the charts with the results once they're available.
GitLab also has a mechanism which can wait for another pipeline.
However, it can't be utilized here, since there are variables which
need to be passed in when the pipeline is triggered (like protocol to be
tested, load, runtime etc.). This isn't currently supported by the
GitLab feature.
Multiple CI jobs may utilize a baseline version, i.e. the version that
the current code should be tested against when doing comparative
testing. To avoid repeating the non-trivial detection of the baseline
version, move it into a separate job which creates an environment file
that subsequent jobs may require via `needs` option. It is then possible
to use the variable(s) defined in the script section of the new job.
When serve-stale is enabled and recursive resolution fails, the fallback
to lookup stale data always happens in the cache database. Any
authoritative data is ignored, and only information learned through
recursive resolution is examined.
If there is data in the cache that could lead to an answer, and this can
be just the root delegation, the resolver will iterate further, getting
closer to the answer that can be found by recursing down the root, and
eventually puts the final response in the cache.
Change the fallback to serve-stale to use 'query_getdb()', that finds
out the best matching database for the given query.
Add a test case where serve-stale is enabled on a server that also
servers a local authoritative zone.
The particular case tests a lame delegation and checks if falling
back to serving stale data does not attempt to retrieve the query
by recursing from the root down.
Increasing the initial and freemax sizes for dns_message memory pools
restores the root zone performance. The former sizes were suited for
per-dns_message memory pools and we need to bump the sizes up for
per-thread memory pools.
Commit 42d43aa0758513a45b54e0fd0bff4381fdc4d803 made --with-liburcu
depend on --enable-developer. This broke pairwise testing as this new
dependency was not codified in configure.ac. Since the --with-liburcu
option is currently just a convenience for developers, there is no need
to test building against all possible RCU variants in GitLab CI until
they actually work with BIND 9. Update the pairwise testing
"configuration" in configure.ac so that builds with non-standard RCU
variants are not tested.
The client connection timeout was set to just one second, which might
not be enough on busy systems (and the CI machines are oh-boy-busy).
Bump the server timeouts to 10 seconds and client timeouts to 5 seconds,
this will make the unit test run a little bit longer, but it should be
more reliable.
Previously, the isccc_ccmsg_invalidate() was called from conn_free() and
this could lead to netmgr calling control_recvmessage() after we
detached the reading controlconnection_t reference, but it wouldn't be
the last reference because controlconnection_t is also attached/detached
when sending response or running command asynchronously.
Instead, move the isccc_ccmsg_invalidate() call to control_recvmessage()
error handling path to make sure that control_recvmessage() won't be
ever called again from the netmgr.
The controlconf channel runs single-threaded on the main thread.
Replace the listener->connections locking with check that we are still
running on the thread with TID 0.
The lock-file configuration (both from configuration file and -X
argument to named) has better alternatives nowadays. Modern process
supervisor should be used to ensure that a single named process is
running on a given configuration.
Alternatively, it's possible to wrap the named with flock(1).
This is first step in removing the lock-file configuration option, it
marks both the `lock-file` configuration directive and -X option to
named as deprecated.
When -X is used the 'lock-file' option change detection condition
is invalid, because it compares the 'lock-file' option's value to
the '-X' argument's value instead of the older 'lock-file' option
value (which was ignored because of '-X').
Don't warn about changing 'lock-file' option if '-X' is used.
It is obvious that the '!cfg_obj_asstring(obj)' check should be
'cfg_obj_asstring(obj)' instead, because it is an AND logic chain
which further uses 'obj' as a string.
Fix the error.
