In the test the quota is set to 400, and softquota to 90%*400=360.
We first attach to quota, and then if we're above softquota we
drop the oldest client. With new socket code and taskmgr it's
parallel enough to create a race between multiple instances doing
'attach to quota' and then 'drop oldest client' - making number
of clients go over softquota. It's not a problem in real life, as
it's just soft quota.
While implementing the new unit testing framework cmocka, it was found that the
BIND 9 code doesn't compile when assertions are disabled or replaced with any
function (such as mock_assert() from cmocka unit testing framework) that's not
directly recognized as assertion by the compiler.
This made the compiler to complain about blocks of code that was recognized as
unreachable before, but now it isn't.
The changes in this commit include:
* assigns default values to couple of local variables,
* moves some return statements around INSIST assertions,
* adds __builtin_unreachable(); annotations after some INSIST assertions,
* fixes one broken assertion (= instead of ==)
Tell the user explicitly about their mistakes:
* Unknown options, e.g. -list instead of -dump
or -delete instead of -remove.
* Unknown view names.
* Excess arguments.
Include the view name in `rndc nta -dump` output, for consistency with
the NTA add and remove actions.
When removing an NTA from all views, do not abort with an error if the
NTA was not found in one of the views.
Ensure that serve-stale works as expected when returning stale answers
is enabled, the authoritative server does not respond, and there is no
cached answer available.
To minimize the effort required to set up IANA root zone mirroring,
define a default master server list for the root zone and use it when
that zone is to be mirrored and no master server list was explicitly
specified. Contents of that list are taken from RFC 7706 and are
subject to change in future releases.
Since the static get_masters_def() function in bin/named/config.c does
exactly what named_zone_configure() in bin/named/zoneconf.c needs to do,
make the former non-static and use it in the latter to prevent code
duplication.
