Create a utility package for code shared by the python tests. The
utility functions should use reasonable defaults and be split up into
modules according to their functionality.
Ensure assert rewriting is enabled for the modules to get the most
useful output from pytest.
By default, the useful assertion message rewrite is used by pytest for
test modules only. Since another module is imported with shared
functionality, ensure it has pytest's assertion message rewriting
enabled to obtain more debug information in case it fails.
This file is executed outside of pytest with pure python, which doesn't
do any AssertionError message rewriting like pytest. Ensure the assert
messages in this file provide a useful debug message.
Resolve "Crash on shutdown when DNSSEC validation is running: ENSURE(isc_mempool_getallocated(*namepoolp) == 0) failed"
Closes#4462 and #4384
See merge request isc-projects/bind9!8526
With shared name memory pools (f5af981831)
the message needs to be destroyed before the view is detached which
in turn detaches the resolver which checks that all resources have
been returned.
When all the servers are exhausted for UDP setup emit "no servers
could be reached" in udp_ready(). This message can also be emitted
for a recv_done() error and for TCP connection failure similarly.
Rewrite and reorganize the test documentation to focus on the pytest
runner, omit any mentions of the legacy runner which are no longer
relevant, and mention a few pytest tricks.
The new unit isc_mem_overmem unit test sets hi and lo water marks and
then does allocations to go over:
0. x < lo_water
1. lo_water < x < hi_water
2. x > hi_water
3. lo_water < x < hi_water
4. < lo_water
Previously, there were two methods of working with the overmem
condition:
1. hi/lo water callback - when the overmem condition was reached
for the first time, the water callback was called with HIWATER
mark and .is_overmem boolean was set internally. Similarly,
when the used memory went below the lo water mark, the water
callback would be called with LOWATER mark and .is_overmem
was reset. This check would be called **every** time memory
was allocated or freed.
2. isc_mem_isovermem() - a simple getter for the internal
.is_overmem flag
This commit refactors removes the first method and move the hi/lo water
checks to the isc_mem_isovermem() function, thus we now have only a
single method of checking overmem condition and the check for hi/lo
water is removed from the hot path for memory contexts that doesn't use
overmem checks.
The ns2/named-alt3.conf.in config file was removed in
f8e264ba6d. From then on, system test
reports:
sed: can't read ns2/named-alt3.conf.in: No such file or directory"
Drop the last remnant of ns2/named-alt3.conf.in.
The definitions of the "ci-variables" and "cross-version-config-tests"
GitLab CI jobs were accidentally added in the .gitlab-ci.yml section
that claims to only contain job templates. Move the definitions of
these two jobs to a more appropriate location in .gitlab-ci.yml, without
changing the job definitions themselves.
All currently supported BIND 9 branches use xz-packed tarballs for
source code distribution. Having a variable with a lengthy name that
only holds two characters does not improve readability - it was only
useful for maintaining .gitlab-ci.yml consistency between BIND 9.11 and
all the newer branches, but that era has come to an end a while ago.
Replace all occurrences of the TARBALL_EXTENSION variable in
.gitlab-ci.yml with a fixed string ("xz") to simplify the contents of
that file.
