It would be too easy if we could just call sorted(). Thanks to zone
grammar the most important key "type" gets sorted near end, so we pull
it up to the top using a hack.
It turns out the tree of dictionaries is not the best structure to
represent our grammar, unfortunatelly. The problem is that "zone" has
several context-dependent variants which change meaning of "zone" based
on inner field "type".
Redesigning the whole structure does not seem to be worth, so I settled
on this terrible hack.
A new flag
.. namedconf:statement::
:suppress_grammar:
suppresses pretty-printing grammar.
It is useful mostly for zones because each zone has it's own grammar, so
printing all of them at once usually does not make sense.
The utility detects statements which use the same name (e.g.
max-zone-ttl) but use different grammar in different contexts. These
typically need special case in docs.
It transforms named.conf/rndc.conf grammar from text format into Python
dictionary. This allows granular access to grammar elements.
Beware: It heavity depens on cfg_test output format!
The next commit is going to add parser for ISC configuration format.
To simplify the parser the grammar files in doc/misc are no longer
line-wrapped as handling it would make the grammar parser unnecessairly
complicated.
This affects visible output in the ARM, but in the end we are going to
replace the auto-generated .rst files with grammar pretty printed, so
formatting of these files does not matter in practical terms.
The "glue-cache" option was marked as deprecated by commit
5ae33351f2 (first released in BIND 9.17.6,
back in October 2020), so now obsolete that option, removing all code
and documentation related to it.
Note: this causes the glue cache feature to be permanently enabled, not
disabled.
This commit ensures that on reconfiguration a proper value for HTTP
connections limit is picked up.
The commit also refactors how listeners settings are updated so that
there is less code duplication.
This way only quota size is passed to the interface/listener
management code instead of a quota object. Thus, we can implement
updating the quota object size instead of recreating the object.
Remove the duplication from the defaultconf and inherit the values
not set in the "insecure" policy from the "default" policy. Therefore,
we must insist that the first read built-in policy is the default one.
Most of the settings (durations) are already inheriting from the default
because they use the constants from lib/dns/kasp.h. We need them as
constants so we can use them in named-checkconf to verify the policy
parameters.
The NSEC(3) parameters and keys should come from the actual default
policy. Change the call to cfg_kasp_fromconfig() to include the default
kasp. We also no longer need to corner case where config is NULL we load
the built-in policy: the built-in policies are now loaded when config is
set to named_g_config.
Finally, add a debug log (it is useful to see which policies are being
loaded).
