Description Lukas Javorsky 2022-02-16 08:17:14 UTC

Description of problem:
When commit (http://pkgs.devel.redhat.com/cgit/rpms/mariadb/commit/?id=a31d9223ce065200d4d6cb01185a7d0b681d5b5b) was introduced to the RHEL-8 builds, covscan started to have a hard time because it's hardly affected by this.

After a discussion with kdudka we agreed that if MariaDB really doesn't need to use less parallelism we shouldn't do it.

This means that we have to investigate if this commit is necessary and if so, we should give a good reason why and close this BZ.

If we don't need to do that anymore, we should revert this commit.

Convscan wastes a significant number of resources when it's bottlenecked by this commit, which is the reason for this investigating work we should do here.

Version-Release number of selected component (if applicable):
MariaDB-10.5 RHEL-8 (https://src.osci.redhat.com/rpms/mariadb/blob/stream-10.5-rhel-8.6.0/f/mariadb.spec#_907)
MariaDB-10.5 RHSCL (https://src.osci.redhat.com/rpms/mariadb/blob/rhscl-3.9-rh-mariadb105-rhel-7/f/mariadb.spec#_978)

NOTE: This change is only part of the MariaDB-10.5 version and only in RHEL-8 and RHSCL (Fedora and RHEL-9 doesn't contain this change)
