Based on measurements done on BIND v9_19_2 using bank. TLD and a
synthetitc fullly signed zone, using RSASHA256 and ECDSAP256SHA256
algorithms with NSEC and NSEC3 without opt-out.

This section was completely out of date. Current measurements on dataset
Telco EU 2022-02 and BIND 9.19.1 indicate absolutely different results
than described in the old version of the text.

Guide in this repo is tied to latest version anyway, so let's not even
mention ancient versions of BIND.
This also solves the OpenSSL question because it is now mandatory for
build, which subsequently removes the entropy problem - so let's not
mention it either.

With the recent Coverity Scan 2021.12 version, Python 3 scripts are
being analyzed in addition to C files. The --fs-capture-search option
scripts for Coverity Scan analysis should be added to leverage this
feature.
(cherry picked from commit b4a2674d98)
Downloading and unpacking Coverity Scan analysis tool tarball
(cov-analysis-linux64.tgz) to $CI_PROJECT_DIR interferes with the
execution of the analysis tool when the --fs-capture-search option is
used because the tool starts to analyze some of its Javascript files.
(There's the --fs-capture-search-exclude-regex <path> option, but I
failed to find a way to make it work.)
(cherry picked from commit 1333bdf67e)
The coverity CI job cache feature is used to ensure that the 1 GB
cov-analysis-linux64.tgz file is being cached on GitLab CI runner, where
it was downloaded in the past. This feature does not seem to work
anymore; given that the proper solution to creating distributed cache is
complicated, better to drop the feature altogether.

Under specific rare timing circumstances the uv_read_start() could
fail with UV_EINVAL when the connection is reset between the connect (or
accept) and the uv_read_start() call on the nmworker loop. Handle such
situation gracefully by propagating the errors from uv_read_start() into
upper layers, so the socket can be internally closed().

Python codestyle is now handled by black and other issues are checked by
pylint. Flake8 checking has been made redundant and is thus removed as
obsolete.

When there are multiple record datasets in a database node of a catalog
zone, and BIND encounters a soft error during processing of a dataset,
it breaks from the loop and doesn't process the other datasets in the
node.
There are cases when this is not desired. For example, the catalog zones
draft version 5 states that there must be a TXT RRset named
`version.$CATZ` with exactly one RR, but it doesn't set a limitation
on possible non-TXT RRsets named `version.$CATZ` existing alongside
with the TXT one. In case when one exists, we will get a processing
error and will not continue the loop to process the TXT RRset coming
next.
Remove the "break" statement to continue processing all record datasets.

In the cases where we test SOA serial updates and TTL updates, we check
if for "all zones loaded" to ensure the new zone content is loaded. But
this is the unsigned zone, the signed zone still needs to be produced.
There is thus a timing issue where the dig request comes in before
the signing process has finished.
Add a retry quiet to mitigate against it.

Messages with log levels INFO or higher are flagged for manual review.
Purpose of this check is to prevent debug logs to being released with
too-high log level.

After enormous amount of bikesheding about colors we decided to override
ReadTheDocs default style for literals (``literal`` in the RST markup).
Justification:
- The default RTD "light red literal on white background" is hard to
read. https://webaim.org/resources/contrastchecker/ reports that text
colored as rgb(231, 76, 60) on white background has insufficient
contrast.
- The ARM has enormous amount of literals all over the place and thus
one sentence can contain several black/red/black color changes. This
is distracting. As a consequence, the ARM looks like a Geronimo
Stilton book.
What we experimented with as replacements for red:
- Green - way too distracting
- Blue - too similar to "usual clickable link"
- Violet - too Geronimo Stilton style
- Brown - better but still distracting
After all the bikesheding we settled on black, i.e. the same as all
"normal" text. I.e. the color is now the same and literals are denoted
by monospaced font and a box around the literal. This has best contrast
and is way less distracting than it used to be.
This lead to a new problem: Internal references to "term definitions"
defined using directives like .. option:: were rendered almost the same
as literals:
- References: monospaced + box + bold + clickable
- Literals: monospaced + box To distinguish these two we added black
dotted underline to clickable references.
I hereby declare the bikeshed painted.

RTD style default never wraps <th> and <td> elements and that just does
not work for real sentences or any other long lines.
We can reconsider styling some tables separately, but at the moment we
do not have use for tables with long but unwrappable lines so it's
easier to allow wrapping globally.
(cherry picked from commit a5dd98ac1b)
When processing a catalog zone update, skip processing records with
DNSSEC-related and ZONEMD types, because we are not interested in them
in the context of a catalog zone, and processing them will fail and
produce an unnecessary warning message.
