Add a GitLab CI job (which is run only if all other jobs in a pipeline
succeed) that builds a BIND release tarball, i.e. fetches the source
tarball from the tarball building job, creates Windows zips, puts
certain parts of BIND documentation into the appropriate places, and
packs it all up into a single tarball whose contents can be subsequently
signed and published.
Add a system test job for binaries created by Visual Studio in the
"Debug" build configuration to GitLab CI so that they can be tested
along their "Release" counterparts when necessary.
Add a Visual Studio build job using the "Debug" build configuration to
GitLab CI without enabling it for every pipeline as it takes about twice
as long to complete as its "Release" counterpart.
Add a set of jobs to GitLab CI that create a BIND source tarball and
then build and test its contents. Run those extra jobs only when a tag
is pushed to the Git repository as they are only meant to be sanity
checks of BIND source tarball contents.
The util/prepare-softhsm2.sh script is useful for initializing a working
SoftHSM environment which can be used by unit tests and system tests.
However, since it is a test-specific script, it does not really belong
in the util/ subdirectory which is mostly pruned during the BIND source
tarball creation process. Move the prepare-softhsm2.sh script to
bin/tests/ so that its location is more appropriate for its purpose and
also so that it does not get removed during the BIND source tarball
creation process, allowing it to be used for setting up test
environments for tarball-based builds.
Convert the logic (currently present in the form of "rm -rf" calls in
util/kit.sh) for removing files and directories which are tracked by Git
but redundant in release tarballs into a set of .gitattributes rules
which allow the same effect to be achieved using "git archive".

The LC_ALL=C assignments in the "idna" system test, which were only
meant to affect a certain subset of checks, in fact persist throughout
all the subsequent checks in that system test. That affects the test's
behavior and is misleading.
When the "VARIABLE=value command ..." syntax is used in a shell script,
in order for the variable assignment to only apply to "command", the
latter must be an external binary; otherwise, the VARIABLE=value
assignment persists for all subsequent commands in a script:
$ cat foo.sh
#!/bin/sh
foo() {
/bin/sh bar.sh
}
BAR="baz0"
BAR="baz1" /bin/sh bar.sh
echo "foo: BAR=${BAR}"
BAR="baz2" foo
echo "foo: BAR=${BAR}"
$ cat bar.sh
#!/bin/sh
echo "bar: BAR=${BAR}"
$ /bin/sh foo.sh
bar: BAR=baz1
foo: BAR=baz0
bar: BAR=baz2
foo: BAR=baz2
$
Fix by saving the value of LC_ALL before the relevant set of checks in
the "idna" system test, restoring it afterwards, and dropping the
"LC_ALL=C command ..." syntax.
- make tcp listening IPC pipe name saner
- put the pipe in /tmp on unices
- add pid to the pipe name to avoid conflicts between processes
- fsync directory in which the pipe resides to make sure that the
child threads will see it and be able to open it
even when worker is paused (e.g. interface reconfiguration). This is
needed to prevent deadlocks when reconfiguring interfaces - as network
manager is paused then, but we still need to stop/start listening.
- Proper handling of TCP listen errors in netmgr - bind to the socket first,
then return the error code.
When listening for TCP connections we create a socket, bind it
and then pass it over IPC to all threads - which then listen on
in and accept connections. This sounds broken, but it's the
official way of dealing with multithreaded TCP listeners in libuv,
and works on all platforms supported by libuv.
In decrement_reference only test node->down if the tree lock
is held. As node->down is not always tested in
decrement_reference we need to test that it is non NULL in
cleanup_dead_nodes prior to removing the node from the rbt
tree. Additionally it is not always possible to aquire the
node lock and reactivate a node when adding parent nodes.
Reactivate such nodes in cleanup_dead_nodes if required.
Before, the zero system test could get stuck almost infinitely, because
the first test sends > 300 queries with 5 seconds timeout on each in
each pass. If named crashed early, it would took the test more than 4
hours to properly timeout.
This commit introduces a "watchdog" on the dig commands running in the
background and failing the test on timeout, failing any test if any dig
command fails to return successfully, and making the tests.sh script
shellcheck clean.
