Explanation for removed notes follow:
| * Enable creation of the log file by logrotate (needed since
| /var/log/ isn't writable by mysql user); and set the same 640
| permissions we normally use.
This is an ancient artefact.
It originates in this commit from 2012 in the 'mysql' package in Fedora:
https://src.fedoraproject.org/rpms/mysql/c/d3bdaa4a?branch=rawhide
That was at the time, when the DB log resided directly in '/var/log/', rather than '/var/log/some-dir-specific-for-the-DB/'.
Since that is no longer the case, the 'create 600 mysql mysql' directive is no longer necessary.
| * Comment out the actual rotation commands, so that user must edit
| the file to enable rotation. This is unfortunate, but the fact
| that the script will probably fail without manual configuration
| (to set a root password) means that we can't really have it turned
| on by default. Fortunately, in most configurations the log file
| is low-volume and so rotation is not critical functionality.
This is no longer true.
Since MariaDB 10.4, which introduced authentication via the UNIX socket,
the 'root' and 'mysql' users can authenticate without login and password.
So we can go back to using 'mysqladmin', or 'mariadb-admin' in this case, to flush logs

| * Note they are from Fedora 15 / 16
I found no more useful information there. Only information already mentioned in other notes here.
| Update 3/2017
| * it would be big unexpected change for anyone upgrading, if we start shipping it now.
| Maybe it is good candidate for shipping with MariaDB 10.2 ?
Introduction of MariaDB 10.11 is the perfect time.
| * the 'mysqladmin flush logs' doesn´t guarantee, no entries are lost
| during flushing, the operation is not atomic.
| We should not ship it in that state
True, however, no one likely cares about that, in reality, since those logs don't hold any journal-like entries.
Explained here:
https://github.com/MariaDB/server/pull/1556#issuecomment-941886220
| Update 6/2018
| * the SIGHUP causes server to flush all logs. No password admin needed, the only constraint is
| beeing able to send the SIGHUP to the process and read the mysqld pid file, which root can.
| * Submited as PR: https://github.com/MariaDB/server/pull/807
It has been dicussed on the upstream thoroughly and was found far from ideal.
Now, that we can use 'mysqladmin', or 'mariadb-admin' in this case, safely again,
there's no argument to keep using the PID file for flushing logs.
| Update 02/2021
| * Enhance the script as proposed in:
| https://mariadb.com/kb/en/rotating-logs-on-unix-and-linux/
Enhanced again now. Significantly this time, however with a vision that the values will become an OS-independent defaults.
| * Discussion continues in:
| https://jira.mariadb.org/browse/MDEV-16621
Discussion finished.
Better start a new one, if needed.
Revert "Introduce the script for generating sources tarball without a code under a license which was not yet approved for Fedora or RHEL"
This reverts commit 7f8a0e15a6.
Note: MariaDB upstream removed TokuDB SE sources in 10.6.0
Fedora commit: be7c99651a
I've encountered this strange behaviour, staring with MariaDB 10.5.20.
The SPIDER tests, and only them, started to fail in 100% cases on all arches
with wide range of "no space left on device" like errors.
This is interesting, as simmilar issues occured before
only on specific arches or build systems.
I've thought that maybe the full suite, which run before the spider tests,
have left over some data in the memory which would leave less space for the
spider tests.
However swapping order - running the spider test first and the full suite
later didn't help anyhow. The spider tests failed rightaway.
Also, it's interesting that running just the main suite in memory is possible.
This observation should rule out changes in the build system (lowering the
memory limits for builders), as I'd expect that the main suite woould have much
bigger memory need than the spider tests.
--
This leads to a possibility that there is actually a bug in the spider engine
or tests, which cause the unexpected larger memory consumption.
This should be examined further. Sadly I don't have capacity for it now.
