fix(client): Fix columnstore.cnf file
This fix changes option file to apply '--quick' option only for 'mariadb' and 'mysql' clients instead of all MariaDB clients.
Otherwise 'mysqladmin' uses this option, but it doesn't exist. As a result broken CI multinode MTR stage.
[add] managers/certificate.py with CertificateManger class
[mv] creating self-signed certificate logic into CertificateManger class
[add] renew and days_before_expire methods to CertificateManger class
[mv] several certificate dependent constants to managers/certificate.py
[add] CherryPy BackgroundTask to invoke certificate check hourly (3600 secs)
[fix] tests
[fix] bug with txn timer clean (clean_txn_by_timeout, worker and invoking of it)
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.
This changeset enables quick (mariadb -q) mode when columnstore is
installed. Quick mode precludes client CLI program from storing too
much data in memory, preventing out of memory conditions.
This fixes discrepance with the server, which assigns DATE type to
last_day()'s result.
Now we also assigns DATE result type and, also, use proper
dataconvert::Day data structure to return date.
Tests agree with InnoDB.
Also, this patch includes test for MCOL-5669, to show we fixed it.
[add] -P to restore help in mcs_backup_restore.sh
[fix] -f argument default value in both backup and restore wrapper commands
[fix] -i argument behaviour and type + default value
[fix] -P argument position and help for both backup and restore wrapper commands
[fix] disable some pylint warning for both backup and restore wrapper files
When ORDER BY column is not in GROUP BY, is not an aggregate and there
is a SELECT column that is also not an aggregate, there was a problem:
ordering happened on the SELECTed column, not ORDERed one.
This patch fixes that particular problem and also performs some tidying
around newly added aggregate.
[mv] extra/cs_package_manager.sh -> cmapi/scripts/cs_package_manager.sh to pack and deliver the script with cmapi package
[add] cs_package_manager.sh to cmapi package
[fix] download paths for mcs_backup_manager.sh and cs_package_manager.sh
This patch fixes the problem in MCOL-4234 and also generally improves
behavior of GROUP BY.
It does so by introducing a "dummy" aggregate and by wrapping columns
into it. This allows for columns that are not in GROUP BY to be used
more freely, for example, in SELECT * FROM tbl GROUP BY col - all
columns that are not "col" will be wrapped into an aggregate and query
will proceed to execution.
The dummy aggregate itself does nothing more than remember last value
passed into it.
There also an additional error message that tries to explain what types
of expressions can be wrapped into an aggregate.
Limit test containers by memory, fix cgroup path inside the containers by introducing new ugly setting name
