BLOB fields did not work as grouping keys at all, they were assigned value NULL for any value, be it NULL or not. The fix is in the rowaggregation.cpp in the initMapping(), a switch/case branch was added to handle BLOB field copying there. Also, TEXT columns did not distinguish between NULL and empty string in the grouping algorithm, now they do. The fix is in the equals() function, now we specifically check for isNull() equality between values.
Objective
---------
The 'columnstore' test suite includes tests suites aimed at testing MariaDB Columnstore
Database Engine (MCS).
https://mariadb.com/kb/en/mariadb-columnstore/
Test Repo
---------
https://github.com/mariadb-corporation/columnstore-tests/tree/master/mysql-test/suite/columnstore
Test structure
--------------
The current directory structure is shown below:
columnstore/
├── basic
│ ├── r
│ └── t
├── csinternal
│ ├── autopilot
│ │ ├── r
│ │ └── t
│ ├── devregression
│ │ ├── r
│ │ └── t
│ └── include
│ ├── dbt3
│ └── ssb
├── extended
├── include
└── std_data
't' dir contains the tests.
'r' dir contains the expected result files.
'include' dir contains common libraries used by the tests.
'std_data' dir containt test data files.
Test suites:
1. basic
Mostly sanity, high value, shorter execution time tests
2. extended
More complex and involved tests - longer execution time, variations
3. csinternal
Limited to CS internal team - Uses seeded test data. The tests in this are divided into the following two sub-suites:
autopilot - Autopilot cases migrated to MTR
devregression - Part of Dev test suite migrated to MTR
Prerequisites
-------------
1.
MariaDB Server and Columnstore are already installed on the test box, let's call it INSTALL_DIR. Usually it is /usr/share/mysql.
mysql-test is already installed, let's call it MYSQLTEST_DIR. Usually it is /usr/share/mysql-test.
Columnstore-tests local repository, let's call it MCSTEST_DIR. Usually it is columnstore-tests/mysql-test/suite/columnstore
cd MYSQLTEST_DIR
ln -s MCSTEST_DIR MYSQLTEST_DIR/suite/columnstore
2. Only for csinternal tests
For csinternal test run requires the test data 'dbt3' and 'ssb' stored at https://drive.google.com/drive/folders/1dAV4ltxLrvC_7TrZ4zLu42gxx17wzH15?usp=sharing to be available at the following location on the test box:
/data/qa/source/
dbt3
ssb
Setup test environment by running the following:
./mtr --suite=columnstore/csinternal regression_env_setup --extern socket=/var/lib/mysql/mysql.sock
Test Run
--------
Run test suite:
mtr --force --suite=columnstore/basic --extern socket=/var/lib/mysql/mysql.sock
mtr --force --suite=columnstore/extended --extern socket=/var/lib/mysql/mysql.sock
mtr --force --suite=columnstore/csinternal --extern socket=/var/lib/mysql/mysql.sock
mtr --force --suite=columnstore/csinternal/autopilot --extern socket=/var/lib/mysql/mysql.sock
mtr --force --suite=columnstore/csinternal/devregression --extern socket=/var/lib/mysql/mysql.sock
Run individual test:
example
mtr --suite=columnstore/basic mcs12_alter_table.test --extern socket=/var/lib/mysql/mysql.sock
Run by skipping list of tests:
example
mtr --force --skip-test-list=failed.def --suite=columnstore/basic --extern socket=/var/lib/mysql/mysql.sock
failed.def file lists test names in separated lines.
