the change from RBT to QP has changed the contents of generated zone
files slightly: node names are now always absolute, so instead of using
$ORIGIN and relative names, generated zone files use full names for all
records.
this caused a failure in the stub system test, which was grepping for a
relative name in a dumped zone file. using "masterfile-style full" makes
the test pass regardless of the database being used.
The old name "common" clashes with the convention of system test
directory naming. It appears as a system test directory, but it only
contains helper files.
To reduce confusion and to allow automatic detection of issues with
possibly missing test files, rename the helper directory to "_common".
The leading underscore indicates the directory is different and the its
name can no longer be confused with regular system test directories.
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.
Replace most "master/slave" terminology in tests with the preferred
"primary/secondary", with the following exceptions:
- When testing the old syntax
- When master is used in master file and master file format terms
- When master is used in hostmaster or postmaster terms
- When master used in legacy domain names (for example in dig.batch)
- When there is no replacement (for example default-masters)
This test is very simple, two nameserver instances are created:
- ns4: master, with 'minimal-responses yes', authoritative
for example. zone
- ns5: slave, stub zone
The first thing verified is the transfer of zone data from master
to slave, which should be saved in ns5/example.db.
After that, a query is issued to ns5 asking for target.example.
TXT, a record present in the master database with the "test" string
as content.
If that query works, it means stub zone successfully request
nameserver addresses from master, ns4.example. A/AAAA
The presence of both A/AAAA records for ns4 is also verified in the
stub zone local file, ns5/example.db.
