This commit increases the idle TCP timeout to let the DoH quota system
test pass on some platforms (namely FreeBSD 11). It turned out to run
slow enough on the CI under load for the idle TCP timeout to kick in.
This commit refactors the DoH quota system test to make it more
reliable.
The test tries to establish dummy TCP connections to stress the quota
one by one instead of in bulk until the BIND instance cannot answer
queries anymore. This design is better because the test itself does
not need to be aware of the actual quota size.
respdiff needs to be run regularly to identify problems with query
responses discrepancies sooner than after tagging a release.
MAX_DISAGREEMENTS_PERCENTAGE variable is set to 0.5 on the main branch
to make room for a greater number of response disagreements between a
relatively old baseline version and the Development Version.
On the isc_mem water change the old water_t structure could be used
after free. Instead of introducing reference counting on the hot-path
we are going to introduce additional constraints on the
isc_mem_setwater. Once it's set for the first time, the additional
calls have to be made with the same water and water_arg arguments.
Increasing the nodelock count had major impact on the memory footprint
in scenarios where multiple rbtdb structure would be created like
hosting many zones in a single server.
This reverts commit 0344684385 and sets
the nodelock count to previously used values.
Since the forced removal of gcc:sid:i386 in 0aacabc6, we lacked a 32-bit
environment to build and test BIND 9 in the CI. gcc:buster:amd64cross32
adds an environment to cross-compile BIND 9 to 32-bits on Debian Buster
amd64 image with 32-bit BIND 9 dependencies. Commit also adds sanity
checks to ensure that compiled objects are not of the build platform
triplet type.
The support for stat.pl's --restart option was incomplete in run.sh.
This change makes sure it's handled properly and that named.run file is
not being removed by clean.sh when the --restart option is used.
When named failed to start and produced core dump, the core file wasn't
processed by GDB because of run.sh script exiting immediately. This
remedies the limitation, simplifies the surrounding code, and makes the
script shellcheck clean.
