- Add new Ninja and Clang build jobs. This helps to ensure those
toolchains also work in addition to default CMake/gcc.
- Generate dependencies.dot/png to illustrate the CMake/Make/Ninja
build dependencies. Viewing this image and identifying bottle necks
in parallelism can help make the build run faster.
- Enable CUnit tests now as they are fixed on 10.6 (MDEV-25820).
- Limit parallel builds to 2 CPUs (full parallelism needs MDEV-25968) on
CMake/Make. Now only the Ninja builds run full parallel builds as only
Ninja is smart enough to prevent builds failing on resource
over-consumption.
- Enable Gitlab-CI cache for job 'centos8' for ccache so that it builds
faster. Don't use Gitlab-CI cache for other jobs, as it would too easily
use up all free tier storage on Gitlab.com and force users to get a paid
account just for MariaDB builds.
- On other jobs clean away ccache, as it only had a 5% hit rate on single
builds with no downloaded cache.
- Dump full database contents during the test install so that one can
use diff to compare the database contents at different stages and thus
track/debug potential bugs in mariadb-install-db and mariadb-upgrade
code.
Bugfixes:
- Zero out ccache stats before each run so that 'ccache -s' would actually
show the stats for the latest run.
As Travis-CI has stopped offering free testing for open source projects,
and they don't seem to have any plans to revert their new restrictions,
MariaDB no longer has a good CI system outside contributors could run
independently for basic validation before submitting Pull Requests.
Implement a simple Gitlab-CI pipeline that runs basic RPM builds on
one old, one less old and one very new distro release and then do some
basic tests on the RPM packages to validate they installed and the
server actually runs.
