memmove() should be used instead of memcpy() for overlapping memory regions.
Overlapping memory regions itself here are fine, because code simply removes
one element from arbitrary position of an array.
MDEV-20589: Server still crashes in Field::set_warning_truncated_wrong_value
- Use dbug_tmp_use_all_columns() to mark that all fields can be used
- Remove field->is_stat_field (not needed)
- Remove extra arguments to Field::clone() that should not be there
- Safety fix for Field::set_warning_truncated_wrong_value() to not crash
if table is zero in production builds (We have got crashes several times
here so better to be safe than sorry).
- Threat wrong character string warnings identical to other field
conversion warnings. This removes some warnings we before got from
internal conversion errors. There is no good reason why a user would
get an error in case of 'key_field='wrong-utf8-string' but not for
'field=wrong-utf8-string'. The old code could also easily give
thousands of no-sence warnings for one single statement.
In the function test_if_cheaper_ordering we make a decision if using an index is better than
using filesort for ordering. If we chose to do range access then in test_quick_select we
should make sure that cost for table scan is set to DBL_MAX so that it is not picked.
The unit files made systemd print:
systemd[1]: Started MariaDB 10.3.13 database server (multi-instance).
Let's add the instance name, so starting mariadb@foo.service
makes it print:
systemd[1]: Started MariaDB 10.3.13 database server (multi-instance foo).
A CTE can be defined as a table values constructor. In this case the CTE is
always materialized in a temporary table.
If the definition of the CTE contains a list of the names of the CTE
columns then the query expression that uses this CTE can refer to the CTE
columns by these names. Otherwise the names of the columns are taken from
the names of the columns in the result set of the query that specifies the
CTE.
Thus if the column names of a CTE are provided in the definition the
columns of result set should be renamed. In a general case renaming of
the columns is done in the select lists of the query specifying the CTE.
If a CTE is specified by a table value constructor then there are no such
select lists and renaming is actually done for the columns of the result
of materialization.
Now if a view is specified by a query expression that uses a CTE specified
by a table value constructor saving the column names of the CTE in the
stored view definition becomes critical: without these names the query
expression is not able to refer to the columns of the CTE.
This patch saves the given column names of CTEs in stored view definitions
that use them.
mysqld_safe --dry-run needs to either call exit or return, depending if
it is being sourced or not, otherise return can lead to the error:
return: can only `return' from a function or sourced script
The original fix suggestion was proposed by FaramosCZ <mschorm@centrum.cz>
- Enable the test `sphinx.sphinx` which was disabled by MDEV 10986,
comit ee0094d2fd
- Add test case to `sphinx.sphinx` to cover host as localhost instead of `127.0.0.1`
- Add result file for single test
There's an annoying bug that prevents a Sphinx table to connect to a searchd using a host name.
So the example table in the documentation https://mariadb.com/kb/en/library/about-sphinxse/#basic-usage that point's to "localhost" actually doesn't work.
After some investigation I found two errors. The first one is a wrong check after the getaddrinfo call. The second is a wrong usage of the returned struct.
libedit changed it's interface a while ago. MariaDB's cmake file doesn't
recognize the new interface, the compile test fails:
/mariadb-10.2.19/CMakeFiles/CMakeTmp/src.cxx: In function 'int main(int, char**)':
/mariadb-10.2.19/CMakeFiles/CMakeTmp/src.cxx:6:47: error: invalid conversion from 'char*' to 'int' [-fpermissive]
int res= (*rl_completion_entry_function)(0,0);
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~
Fix this by adding a detection for the new interface as well.

Include comment header that describes overrides.
Unit description now includes @VERSION@.
After=syslog.target removed - redunant
Add --basedir=@prefix to prevent /root/.my.cnf lookups. This is
placed after $MYSQLD_OPTIONS in case a user sets a --{no,}default
type options which has to be first in the mysqld arguements.
Additional changes to multi instance (support-files/mariadb@.service.in):
* added @SYSTEMD_EXECSTARTPRE@ / @SYSTEMD_EXECSTARTPOST@
* removed mariadb@bootstrap reference as galera_new_cluster as
it's a little too proment.
* use_galera_new_cluster.conf updated to override pre/post steps
to ensure it has no side effects

In Debian official the MariaDB plugins (.so files) go to a separate
versioned directory so that upgrades and dependencies will work correctly.
This change extends this script to check the /usr/lib/*/mariadb19/..
directory in addition to what it already does. Without this change
the script fails with:
$ mysql_install_db ...
Cannot change ownership of the '/auth_pam_tool_dir' directory
to the 'mysql' user. Check that you have the necessary permissions and
try again.
The flag is_stat_field is not set for the min_value and max_value of field items
inside table share. This is a must requirement as we don't want to throw
warnings of truncation when we read values from the statistics table to the column
statistics of table share fields.
Fixes bug introduced in commit 5415002.
Using script run-time filename does not always work. One cannot assume
that the filename is always the same as there might be temporary file
names used by dpkg in certain situations. See Debian #920415.
The same fix has been successfully in use in Debian official packages
since February 2019:

Problem:
=======
During dropping of fts index, InnoDB waits for fts_optimize_remove_table()
and it holds dict_sys->mutex and dict_operaiton_lock even though the
table id is not present in the queue. But fts_optimize_thread does wait
for dict_sys->mutex to process the unrelated table id from the slot.
Solution:
========
Whenever table is added to fts_optimize_wq, update the fts_status
of in-memory fts subsystem to TABLE_IN_QUEUE. Whenever drop index
wants to remove table from the queue, it can check the fts_status
to decide whether it should send the MSG_DELETE_TABLE to the queue.
Removed the following functions because these are all deadcode.
dict_table_wait_for_bg_threads_to_exit(),
fts_wait_for_background_thread_to_start(),fts_start_shutdown(), fts_shudown().
Problem:
=======
Transaction left with nonempty table locks list. This leads to
assumption that table_locks is not subset of trx_locks. Problem is that
lock_wait_timeout_thread() doesn't remove the table lock from
table_locks for transaction.
Solution:
========
In lock_wait_timeout_thread(), remove the lock from table vector of
transaction.
- Fixes a situation in which a thread gets BF aborted and does not send the reply back to
the client, even though the connection is still alive. That caused
both sides to hang waiting for the next message. Now we explicitly
check that the connection is still alive.
- MTR test for the above
- Replaced thd->killed assignments to thd->reset_kill_query where applicable.

Backport Bug#45852 Semisynch: Last_IO_Error: Fatal error: Failed
to run 'after_queue_event' hook
Errors when send reply to master should never cause the IO thread
to stop, because master can fall back to async replication if it
does not get reply from slave.
The problem is fixed by deliberately ignoring the return value of
slave_reply.
Command COM_SHUTDOWN was rejected in non-Primary because
server_command_flags[COM_SHUTDOWN] had value CF_NO_COM_MULTI
instead of CF_SKIP_WSREP_CHECK.
As a fix removed assignment
server_command_flags[CF_NO_COM_MULTI]= CF_NO_COM_MULTI
which overwrote server_command_flags[COM_SHUTDOWN].
