The initial tcp statistics test was not testing tcp-highwater counter,
but only initial number of current TCP clients, so this missing test was
added to ensure initial tcp-highwater value is correct.
Make the "tcp" system test fail if the Python tool used for establishing
TCP connections (ans6) logs a result different than "OK" after
processing a command sent to it (as that means the tool was unable to
successfully perform the requested action), with the exception of
cleanup errors at the end of the test which can be safely ignored. Note
that the tool not returning any result at all in 10 seconds is still a
fatal error in all cases.
With the netmgr in use, named may start answering queries before zones
are loaded. This can cause transient failures in system tests after
servers are restarted or reconfigured. This commit adds retry loops
and sleep statements where needed to address this problem.
Also incidentally silenced a clang warning.
Ensure any unexpected failure in the "tcp" system test causes it to be
immediately interrupted with an error to make the aforementioned test
more reliable. Since the exit code for "expr 0 + 0" is 1, the status
variable needs to be updated using arithmetic expansion.
In the TCP high-water checks, "rndc stats" is run after ans6 reports
that it opened the requested number of TCP connections. However, we
fail to account for the fact that ns5 might not yet have called accept()
for these connections, in which case the counts output by "rndc stats"
will be off. To prevent intermittent "tcp" system test failures, allow
the relevant connection count checks to be retried (just once, after one
second, as that should be enough for any system to accept() a dozen TCP
connections under any circumstances).
Add a shell function which is used in the "tcp" system test, but has
been accidentally omitted from !2425. Make sure the function does not
change the value of "ret" itself, so that the caller can decide what to
do with the function's return value.
- all tests with "recursion yes" now also specify "dnssec-validation yes",
and all tests with "recursion no" also specify "dnssec-validation no".
this must be maintained in all new tests, or else validation will fail
when we use local root zones for testing.
- clean.sh has been modified where necessary to remove managed-keys.bind
and viewname.mkeys files.
- add CHANGES note
- update copyrights and license headers
- add -j to the make commands in .gitlab-ci.yml to take
advantage of parallelization in the gitlab CI process

The merge also needed to update files in legacy and tcp system tests
(newly introduced in master after branch was created) to introduce use
of lockfile.
