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.
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.
Test zones with various escape sequences and filesystem seperator
characters.
* escaped double quote (\")
* escaped escape (\\)
* escaped decimal byte value (\032)
* slash seperator (/)
The system tests currently uses patchwork of shell scripts which doesn't
offer proper error handling.
This commit introduced option to write new tests in pytest framework
that also allows easier manipulation of DNS traffic (using dnspython),
native XML and JSON manipulation and proper error reporting.
Add recursive "test" and "unit" rules, which execute "make check"
in specific directories - "make test" runs the system tests, and
"make unit" runs the unit tests.
The current script used ephemeral port range which clashed with the
ports used by the tools (dig, ...), and the range always started with
the first port and there was 100 ports allocated for each system test.
In this commit, the first port has been randomized, the get_ports.sh
script outputs the variables (the output has to be eval'ed from run.sh)
and there's less waste in the port range.
There are several improvements over the default/previous behaviour of
the test log driver and log compiler:
* The system-test-driver.sh was dropped (it was used incorrectly)
* The run.sh script is now both log compiler and cli script to run
individual tests
* The custom-test-driver was added as extended version of the automake
test-driver with capability to tee the test output to stdout when
`--verbose yes` is passed to it (you can use LOG_DRIVER_FLAGS to
add the option by default)
* Makefile.am has been extended to honor V=1 for the system tests
test-driver (e.g. V=1 adds `--verbose yes` to AM_LOG_DRIVER_FLAGS)
