Use str.format() instead of f-strings in Python system tests to enable
them to work on Python 3 versions older than 3.6 as the latter is not
available on some operating systems used in GitLab CI that are still
actively supported (CentOS 6, Debian 9, Ubuntu 16.04).
Add a system test that counts how many address fetches are made
for different numbers of NS records and checks that the number
are successfully limited.
as the update triggers by the rndc command to clear the signing records
may not have completed by the time the subsequent rndc command to test
that the records have been removed is commenced. Loop several times to
prevent false negative.
the dnstap test was pausing for 20 seconds to search for a string in
named.run, which only appears if named is built with --enable-developer or
--enable-querytrace.
wire_test is not only used by the dnstap system test, but also in
fuzz testing. it doesn't need to be installed, but it's useful to have it
built when BIND is. this commit moves it back from bin/tests/system to
bin/tests, as a noinst_PROGRAM so that it's built by "make all" but
not installed.
The `statschannel/ns2/` was missing `manykeys.db.in`, but the test
succeeded even when `setup.sh` (or `clean.sh`) failed to execute. This
commit makes run.sh to run in stricter mode and fail the test
immediately when `clean.sh` or `setup.sh` fails.
The ARM and the manpages have been converted into Sphinx documentation
format.
Sphinx uses reStructuredText as its markup language, and many of its
strengths come from the power and straightforwardness of
reStructuredText and its parsing and translating suite, the Docutils.
There were two errors:
1. get_random() function was returning random number with leading zeros
that could lead the shell to interpret the number as octal value
instead of decimal. The surrounding whitespace was also causing
problems.
2. The calculation of the port was off, it was adding the whole range
and not just the min port to the base.
The introduction of netmgr doubled the number of threads from which
dnstap data may be logged: previously, it could only happen from within
taskmgr worker threads; with netmgr, it can happen both from taskmgr
worker threads and from network threads. Since the argument passed to
fstrm_iothr_options_set_num_input_queues() was not updated to reflect
this change, some calls to fstrm_iothr_get_input_queue() can now return
NULL, effectively preventing some dnstap data from being logged.
Whether this bug is triggered or not depends on thread scheduling order
and packet distribution between network threads, but will almost
certainly be triggered on any recursive resolver sooner or later. Fix
by requesting the correct number of dnstap input queues to be allocated.
