isc_event_allocate() calls isc_mem_get() to allocate the event structure. As
isc_mem_get() cannot fail softly (e.g. it never returns NULL), the
isc_event_allocate() cannot return NULL, hence we remove the (ret == NULL)
handling blocks using the semantic patch from the previous commit.
When updating the statistics for RRset types, if a header is marked
stale or ancient, the appropriate statistic counters are decremented,
then incremented.
Also fix some out of date comments.
The stale RR types are now printed with '#'. This used to be the
prefix for RR types that were marked ancient, but commit
df50751585 changed the meaning. It is
probably better to keep '#' for stale RR types and introduce a new
prefix for reintroducing ancient type stat counters.
- this required modification to the code that generates grammar text for
the documentation, because the "dnssec-lookaside" option spanned more
than one line in doc/misc/options, so grepping out only the lines
marked "// obsolete" didn't remove the whole option. this commit adds
an option to cfg_test to print named.conf clauses only if they don't
have the obsolete, ancient, test-only, or not-yet-implemented flags
set.
Add a helper shell function, rndc_dumpdb(), which provides a convenient
way to call "rndc dumpdb" for a given server with optional additional
arguments. Since database dumping is an asynchronous process, the
function waits until the dump is complete before returning, which
prevents false positives in system tests caused by inspecting the dump
before its preparation is finished. The function also renames the dump
file before returning so that it does not get overwritten by subsequent
calls; this retains forensic data in case of an unexpected test failure.
Previously isc_thread_join() would return ISC_R_UNEXPECTED on a failure to
create new thread. All such occurences were caught and wrapped into assert
function at higher level. The function was simplified to assert directly in the
isc_thread_join() function and all caller level assertions were removed.
Previously isc_thread_create() would return ISC_R_UNEXPECTED on a failure to
create new thread. All such occurences were caught and wrapped into assert
function at higher level. The function was simplified to assert directly in the
isc_thread_create() function and all caller level assertions were removed.
Multiple resolvers in the "wildcard" system test are configured with a
single root hint: "ns.root-servers.nil", pointing to 10.53.0.1, which is
inconsistent with authoritative data served by ns1. This may cause
intermittent resolution failures, triggering false positives for the
"wildcard" system test. Prevent this from happening by making ns2, ns3,
and ns5 use root hints corresponding to the contents of ns1/root.db.in.
The isc-config.sh script was introduced before pkg-config as is a purely
historical thing. There are two reason for removal of isc-config.sh scripts:
a) The BIND 9 libraries are now meant to be used only from BIND 9, so there's no
reason to provide convenience script to link with the libraries.
b) Even if that was not the case, we should and would replace the isc-config.sh
with respective pkg-config (.pc) file for every library.
With the move of the normal output to stdout, we need a way how to silence the
extra output, so the signed file name can be captured in a simple way. This
commit adds `-q` command line option that will silence all the normal output
that get's printed from both tools.
The lib/dns/zoneverify.c output was hardwired to stderr, which was inconsistent
with lib/dns/dnssec.c. This commit changes zoneverify.c to print the normal run
information to caller supplied function - same model as in the lib/dns/dnssec.c.
