Add more tests to the dnstap system test to roll with different values.
Touch some files to make sure the number of existing files exceed the
number that we want to keep.
Add a test to the logfileconfig system test for the increment suffix.
Removing old timestamp or increment versions of log backup files did
not work when the file is an absolute path: only the entry name was
provided to the file remove function.
The dirname was also bogus, since the file separater was put back too
soon.
Fix these issues to make log file rotation work when the file is
configured to be an absolute path.
when printing the result of a query, delv +ns repeated the
answer RRset as many times as there were records in the RRset;
this has been fixed by suppressing the printing of records with
the same name and type as the preceding one.
`UINT64_C(UINT64_MAX)' is redundant and leads to a compilation error
since UINT64_C involves token concatenation, causing the check to fail.
This change fixes that by using UINT64_MAX directly, and including the
appropriate header.

when the branch implementing mutex_test was rebased and merged,
a rebasing error was missed: the isc_threadresult and isc_threadarg
types no longer exist.
Add simple mutex unit test and mutex benchmark. The benchmark compares
the pthread mutext with isc mutex implementation, so it's mainly useful
when developing a new isc mutex implementation.
All the per-loop `libuv` setup remains in `isc_loop`, but the per-thread
RCU setup is moved to `isc_thread` alongside the other per-thread setup.
This avoids repeating the per-thread setup for `call_rcu()` helpers,
and explains a little better why some parts of the per-thread setup
is missing for `call_rcu()` helpers.
This also removes the per-loop `call_rcu()` helpers as we refactored the
isc__random_initialize() in the previous commit.
Instead of writing complicated wrappers for every thread, move the
initialization back to isc_random unit and check whether the random seed
was initialized with a thread_local variable.
Ensure that isc_entropy_get() returns a non-zero seed.
This avoids problems with thread sanitizer tests getting stuck in an
infinite loop.
Remove the `isc_threadarg_t` and `isc_threadresult_t`
typedefs which were unhelpful disguises for `void *`,
and free the dummy jemalloc allocation sooner.
When liburcu is not installed from a system package, its headers are
not treated as system headers by the compiler, so BIND's -Werror and
other warning options take effect. The liburcu headers have a lot
of inline functions, some of which do not use all their arguments,
which BIND's build treats as an error.
This commit allows BIND 9 to be compiled with different flavours of
Userspace RCU, and improves the integration between Userspace RCU and
our event loop:
- In the RCU QSBR, the thread is put offline when polling and online
when rcu_dereference, rcu_assign_pointer (or friends) are called.
- In other RCU modes, we check that we are not reading when reaching the
quiescent callback in the event loop.
- We register the thread before uv_work_run() callback is called and
after it has finished. The rcu_(un)register_thread() has a large
overhead, but that's fine in this case.
There's a recurring pattern walking the ISC_LISTs that just repeats over
and over. Add two macros:
* ISC_LIST_FOREACH(list, elt, link) - walk the static list
* ISC_LIST_FOREACH_SAFE(list, elt, link, next) - walk the list in
a manner that's safe against list member deletions
When OPTOUT was in use we didn't ensure that NSEC3 records
for orphaned empty-non-terminals where removed. Check if
there are orphaned empty-non-terminal NSEC3 even if there
wasn't an NSEC3 RRset to be removed in dns_nsec3_delnsec3.
'-T transferinsecs' makes named interpret the max-transfer-time-out,
max-transfer-idle-out, max-transfer-time-in and max-transfer-idle-in
configuration options as seconds instead of minutes.
'-T transferslowly' makes named to sleep for one second for every
xfrout message.
'-T transferstuck' makes named to sleep for one minute for every
xfrout message.
After the dns_xfrin was changed to use network manager, the maximum
global (max-transfer-time-in) and idle (max-transfer-idle-in) times for
incoming transfers were turned inoperational because of missing
implementation.
Restore this functionality by implementing the timers for the incoming
transfers.
