MariaDB server buildbot, among other variations, creates and tests debug CentOS 7 RPM packages.
Columnstore doesn't work on this build. An attempt to create a table deterministically fails with
ERROR 1815 (HY000) at line 1: Internal error: Lost connection to DDLProc
|
To reproduce, install a minimum set of RPM packages from such a build (depending on when you try to reproduce it, the build below may already be gone, just choose the latest available within the same version/builder):
wget http://hasky.askmonty.org/archive/10.5/build-46562/kvm-rpm-centos74-amd64-debug/rpms/MariaDB-columnstore-engine-10.5.16_5.6.4-1.el7.centos.x86_64.rpm
|
wget http://hasky.askmonty.org/archive/10.5/build-46562/kvm-rpm-centos74-amd64-debug/rpms/MariaDB-common-10.5.16-1.el7.centos.x86_64.rpm

|
wget http://hasky.askmonty.org/archive/10.5/build-46562/kvm-rpm-centos74-amd64-debug/rpms/MariaDB-client-10.5.16-1.el7.centos.x86_64.rpm

wget http://hasky.askmonty.org/archive/10.5/build-46562/kvm-rpm-centos74-amd64-debug/rpms/MariaDB-compat-10.5.16-1.el7.centos.x86_64.rpm

wget http://hasky.askmonty.org/builds/mariadb-4.x/latest/kvm-rpm-centos74-amd64-gal/rpms/galera-4-26.4.11-1.el7.centos.x86_64.rpm
|
sudo yum install *.rpm
|
Restart mariadb-columnstore (optionally, it fails either way):
sudo systemctl stop mariadb-columnstore
|
sudo systemctl start mariadb-columnstore
|
Start mariadb service
sudo systemctl start mariadb
|
Try to create a table
sudo mysql -e "create database if not exists cs; use cs; create table t (a int) engine=columnstore"
|
ERROR 1815 (HY000) at line 1: Internal error: Lost connection to DDLProc

Columnstore logs are attached. The occurrence in question is at this timestamp:

Non-debug builds of the same version/revision on the same platform usually work all right.
The difference in options:
|
Problematic debug build
|
cmake . -DBUILD_CONFIG=mysql_release $NO_DEBUGINFO -DCMAKE_COMMAND_DEP=cmake -DRPM=centos74 -DCMAKE_BUILD_TYPE=Debug -DMYSQL_MAINTAINER_MODE=OFF
|
|
Normal release build
|
cmake . -DBUILD_CONFIG=mysql_release $NO_DEBUGINFO -DCMAKE_COMMAND_DEP=cmake -DRPM=centos74
