The artifact lists in clean.sh and extra_artifacts might be slightly
different. The list was updated for each test to reflect the current
state.

All changes in this commit were automated using the command:
shfmt -w -i 2 -ci -bn . $(find . -name "*.sh.in")
By default, only *.sh and files without extension are checked, so
*.sh.in files have to be added additionally. (See mvdan/sh#944)
(manually replayed commit 4cb8b13987)
The changes were mostly done with sed:
find . -name '*.sh' | xargs sed -i 's/`\([^`]*\)`/$(\1)/g'
There have been a few manual changes where the regex wasn't sufficient
(e.g. backslashes inside the `...`) or wrong (`...` referring to docs or
in comments).

Ensure all shell system tests are executed with the errexit option set.
This prevents unchecked return codes from commands in the test from
interfering with the tests, since any failures need to be handled
explicitly.
(cherry picked from commit 01bc805f89)
the default value of dnssec-validation is 'auto', which causes
a server to send a key refresh query to the root zone when starting
up. this is undesirable behavior in system tests, so this commit
sets dnssec-validation to either 'yes' or 'no' in all tests where
it had not previously been set.
this change had the mostly-harmless side effect of changing the cached
trust level of unvalidated answer data from 'answer' to 'authanswer',
which caused a few test cases in which dumped cache data was examined in
the serve-stale system test to fail. those test cases have now been
updated to expect 'authanswer'.

In order to run the shell system tests, the pytest runner has to pick
them up somehow. Adding an extra python file with a single function
for the shell tests for each system test proved to be the most
compatible way of running the shell tests across older pytest/xdist
versions.
Modify the legacy run.sh script to ignore these pytest-runner specific
glue files when executing tests written in pytest.

Previously, an AXFR request would be issued every second while waiting
for the zone to be signed. This might've been the cause of issues in CI
where many tests are running in parallel and any extra load may increase
test instability.
Instead, check for the last NSEC record to have a signature before
commencing the AXFR request to check the zone has been fully signed.
Also increase the time for the zone signing to a total of 60+10 seconds
up from the previous 30.

There's no point in continuing the dupsigs test if a failure is
detected. End the test early to avoid wasting time and resources.
(cherry picked from commit ad647dca13)
Ensure messages from dupsigs system test end up in its log rather than
stdout. Previously, the output was hard to debug when running the tests
in parallel and messages wouldn't end up in the dupsigs.log.
(cherry picked from commit cbe2559f37)
The checkbashisms script reports errors like this one:
script util/check-line-length.sh does not appear to have a #! interpreter line;
you may get strange results
(cherry picked from commit 9e68997cbb)
the dupsigs test is prone to failing on slow CI machines
because the first test can occur before the zone is fully
signed.
instead of just waiting ten seconds arbitrarily, we now
check every second, and allow up to 30 seconds before giving
up.
(cherry picked from commit d9b85cbaae)
Correctly source conf.sh in dupsigs test scripts (fix issue introduced
by 093af1c00a).
Update dupsigs test for dnssec-dnskey-kskonly default. Since v9.17.20,
the dnssec-dnskey-kskonly is set to yes. Update the test to not expect
the additional RRSIG with ZSK for DNSKEY.
Speed up the test from 20 minutes to 2.5 minutes and make it part of the
default test suite executed in CI.
- decrease number of records to sign from 2000 to 500
- decrease the signing interval by a factor of 6
- shorten the final part of the test after last signing (since nothing
new happens there)
Finally, clarify misleading comments about (in)sufficient time for zone
re-signing. The time used in the test is in fact sufficient for the
re-signing to happen. If it wasn't, the previous ZSK would end up being
deleted while its signatures would still be present, which is a
situation where duplicate signatures can still happen.

Properly template the port number in config files with copy_setports.
The test takes two minutes on my machine which doesn't seem like a
proper justification to exclude it from the test suite, especially
considering we run these tests in parallel nowadays. The resource usage
doesn't seems significantly increased so it shouldn't interfere with
other system tests.
There also exists a precedent for longer running system tests that are
already part of the default system test suite (e.g. serve-stale takes
almost three minutes on the same machine).

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.
The ISC_MEM_DEBUGSIZE and ISC_MEM_DEBUGCTX did sanity checks on matching
size and memory context on the memory returned to the allocator. Those
will no longer needed when most of the allocator will be replaced with
jemalloc.
In order to lower the amount of memory allocated at startup by named
instances used in the BIND system test suite, set the default value of
"max-cache-size" for these to 2 megabytes. The purpose of this change
is to prevent named instances (or even entire virtual machines) from
getting killed by the operating system on the test host due to excessive
memory use.
Remove all "max-cache-size" statements from named configuration files
used in system tests ("checkconf" notwithstanding) to prevent confusion
as the "-T maxcachesize=..." command line option takes precedence over
configuration files.
The $SYSTEMTESTTOP shell variable if often set to .. in various shell
scripts inside bin/tests/system/, but most of the time it is only
used one line later, while sourcing conf.sh. This hardly improves
code readability.
$SYSTEMTESTTOP is also used for the purpose of referencing
scripts/files living in bin/tests/system/, but given that the
variable is always set to a short, relative path, we can drop it and
replace all of its occurrences with the relative path without adversely
affecting code readability.
this changes most visble uses of master/slave terminology in tests.sh
and most uses of 'type master' or 'type slave' in named.conf files.
files in the checkconf test were not updated in order to confirm that
the old syntax still works. rpzrecurse was also left mostly unchanged
to avoid interference with DNSRPS.
The rewrite of BIND 9 build system is a large work and cannot be reasonable
split into separate merge requests. Addition of the automake has a positive
effect on the readability and maintainability of the build system as it is more
declarative, it allows conditional and we are able to drop all of the custom
make code that BIND 9 developed over the years to overcome the deficiencies of
autoconf + custom Makefile.in files.
This squashed commit contains following changes:
- conversion (or rather fresh rewrite) of all Makefile.in files to Makefile.am
by using automake
- the libtool is now properly integrated with automake (the way we used it
was rather hackish as the only official way how to use libtool is via
automake
- the dynamic module loading was rewritten from a custom patchwork to libtool's
libltdl (which includes the patchwork to support module loading on different
systems internally)
- conversion of the unit test executor from kyua to automake parallel driver
- conversion of the system test executor from custom make/shell to automake
parallel driver
- The GSSAPI has been refactored, the custom SPNEGO on the basis that
all major KRB5/GSSAPI (mit-krb5, heimdal and Windows) implementations
support SPNEGO mechanism.
- The various defunct tests from bin/tests have been removed:
bin/tests/optional and bin/tests/pkcs11
- The text files generated from the MD files have been removed, the
MarkDown has been designed to be readable by both humans and computers
- The xsl header is now generated by a simple sed command instead of
perl helper
- The <irs/platform.h> header has been removed
- cleanups of configure.ac script to make it more simpler, addition of multiple
macros (there's still work to be done though)
- the tarball can now be prepared with `make dist`
- the system tests are partially able to run in oot build
Here's a list of unfinished work that needs to be completed in subsequent merge
requests:
- `make distcheck` doesn't yet work (because of system tests oot run is not yet
finished)
- documentation is not yet built, there's a different merge request with docbook
to sphinx-build rst conversion that needs to be rebased and adapted on top of
the automake
- msvc build is non functional yet and we need to decide whether we will just
cross-compile bind9 using mingw-w64 or fix the msvc build
- contributed dlz modules are not included neither in the autoconf nor automake
- ns__client_request() is now called by netmgr with an isc_nmhandle_t
parameter. The handle can then be permanently associated with an
ns_client object.
- The task manager is paused so that isc_task events that may be
triggred during client processing will not fire until after the netmgr is
finished with it. Before any asynchronous event, the client MUST
call isc_nmhandle_ref(client->handle), to prevent the client from
being reset and reused while waiting for an event to process. When
the asynchronous event is complete, isc_nmhandle_unref(client->handle)
must be called to ensure the handle can be reused later.
- reference counting of client objects is now handled in the nmhandle
object. when the handle references drop to zero, the client's "reset"
callback is used to free temporary resources and reiniialize it,
whereupon the handle (and associated client) is placed in the
"inactive handles" queue. when the sysstem is shutdown and the
handles are cleaned up, the client's "put" callback is called to free
all remaining resources.
- because client allocation is no longer handled in the same way,
the '-T clienttest' option has now been removed and is no longer
used by any system tests.
- the unit tests require wrapping the isc_nmhandle_unref() function;
when LD_WRAP is supported, that is used. otherwise we link a
libwrap.so interposer library and use that.
For all system tests utilizing named instances, call clean.sh from each
test's setup.sh script in a consistent way to make sure running the same
system test multiple times using run.sh does not trigger false positives
caused by stale files created by previous runs.
Ideally we would just call clean.sh from run.sh, but that would break
some quirky system tests like "rpz" or "rpzrecurse" and being consistent
for the time being does not hurt.
