In RHEL7/RHEL7.1 libcrack behavior seem to have been modified so that
"foobar" password is considered bad (due to descending "ba") earlier than
expected. For details google for cracklib-2.9.0-simplistic.patch.
Adjusted affected passwords not to have descending and ascending sequences.
The test created a file in location relative to the datadir
(a few levels above datadir).
The file was created by MariaDB server (via INTO OUTFILE), and
later removed by mysqltest (via remove_file). The problem is that
when the vardir is a symlink, MariaDB server and mysqltest can
resolve such paths differently. MariaDB server would return back
to where the symlink is located, while mysqltest would go above
the real directory. For example, if the test is run with --mem,
and /bld/5.5/mysql-test/var points at /dev/shm/var_auto_X, then
SELECT INTO OUTFILE created a file in /bld/5.5/mysql-test , but
remove_file would look for it in /dev/shm/.
The test is re-written so that all paths are resolved in perl,
the logic itself hasn't changed.
The reason for the assertion failure is that the update statement for
the minimal row image sets only the PK column in the write_set of the
table to true. On the other hand, the trigger aims to update a different
column.
Make sure that triggers update the used columns accordingly, when being
processed.
when replicating old temporal type fields (that don't store
metadata in the binlog), take the precision from
destination fields.
(this fixes the replication failure, crashes were
fixed in a different commit)
* Total order isolation was started twice for FLUSH TABLES, from
reload_acl_and_cache() and from mysql_execute_command(). Removed
the reload_acl_and_cache() part.
* Removed PXC specific stuff from MTR tests
- Eliminates code duplication in query cache patch
- Reduces the number of iterations in mysql-wsrep#201.test
to shorten the execution time
- Adds a new test case that exercises more scenarios
The admin commands in question are:
> OPTIMIZE
> REPAIR
> ANALYZE
For LOCAL or NO_WRITE_TO_BINLOG invocations of these commands, ie
OPTIMIZE LOCAL TABLE <t1>
they are not binlogged as expected.
Also, in addition, they are not executed under TOI.
Hence, they are not propagated to other nodes.
The effect is same as that of wsrep_on=0.
Also added tests for this.
A WSREP_DEBUG for wsrep_register_hton has also been added.
The galera_flush_local test has also been updated for verifying that effects
of NO_WRITE_TO_BINLOG / LOCAL are equivalent to wsrep_on=0 from wsrep
perspective.

- Fixes query cache so that it is aware of wsrep_sync_wait.
Query cache would return (possibly stale) results to the
client, regardless of the value of wsrep_sync_wait.
- Includes the test case that reproduced the issue.
- Removes useless call to wsrep_xid_init() in wsrep_apply_events().
Transaction's xid is already initialized at that point.
- Adds call to wsrep_set_SE_checkpoint() for committing TOI events
in the applier side.
- Includes test case that reproduced the issue.
There was two problems. Firstly, if page in ibuf is encrypted but
decrypt failed we should not allow InnoDB to start because
this means that system tablespace is encrypted and not usable.
Secondly, if page decrypt is detected we should return false
from buf_page_decrypt_after_read.

Federated/spider/connect engines or replication threads connecting to other host

This is addition to original patch, which adds a test case and amends a macro.
MDEV-9469: 'Incorrect key file' on ALTER TABLE
InnoDB needs to rebuild table if column name is changed and
added index (or foreign key) is created based on this new
name in same alter table.
Fix the doubly questional fix for MySQL Bug#17250787:
* it detected autoinc index by looking for the first index
that starts from autoinc column. never mind one column
can be part of many indexes.
* it used autoinc_field->field_index to look up into internal
innodb dictionary. But field_index accounts for virtual
columns too, while innodb dictionary ignores them.
Find the index by its name, like elsewhere in ha_innobase.

Creating a CONNECT object on client connect and pass this to the working thread which creates the THD.
Split LOCK_thread_count to different mutexes
Added LOCK_thread_start to syncronize threads
Moved most usage of LOCK_thread_count to dedicated functions
Use next_thread_id() instead of thread_id++
Other things:
- Thread id now starts from 1 instead of 2
- Added cast for thread_id as thread id is now of type my_thread_id
- Made THD->host const (To ensure it's not changed)
- Removed some DBUG_PRINT() about entering/exiting mutex as these was already logged by mutex code
- Fixed that aborted_connects and connection_errors_internal are counted in all cases
- Don't take locks for current_linfo when we set it (not needed as it was 0 before)
Cannot do password validation in fix_lex_user(), we don't know
there what "GRANT ... TO user" means - creating a new user with
an empty password (need validation) or granting privileges
to an existing user (no validation needed).
Move validation down into replace_user_table(). And copy into
check_change_password().
This occurs when replication stops with an error, domain-based parallel
replication is used, and the GTID position contains more than one domain.
Furthermore, it relates to the case where the SQL thread is restarted
without first stopping the IO thread.
In this case, the file/offset relay-log position does not correctly
represent the slave's multi-dimensional position, because other domains may
be far ahead of, or behind, the domain with the failing event. So the code
reverts the relay log position back to the start of a relay log file that is
known to be before all active domains.
There was a bug that when the SQL thread was restarted, the
rli->relay_log_state was incorrectly initialised from @@gtid_slave_pos. This
position will likely be too far ahead, due to reverting the relay log
position. Thus, if the replication fails again after the SQL thread restart,
the rli->restart_gtid_pos might be updated incorrectly. This in turn would
cause a second SQL thread restart to replicate from the wrong position, if
the IO thread was still left running.
The fix is to initialise rli->relay_log_state from @@gtid_slave_pos only
when we actually purge and re-fetch relay logs from the master, not at every
SQL thread start.
A related problem is the use of sql_slave_skip_counter to resolve
replication failures in this kind of scenario. Since the slave position is
multi-dimensional, sql_slave_skip_counter can not work properly - it is
indeterminate exactly which event is to be skipped, and is unlikely to work
as expected for the user. So make this an error in the case where
domain-based parallel replication is used with multiple domains, suggesting
instead the user to set @@gtid_slave_pos to reliably skip the desired event.
The problem was that wait_for_slave_io_to_start reported that the io thread
was ready, when it was still initializing. This caused test suite to
continue too early, for example before the semi sync plugin was properly
enabled.
Fixed by introducing a new internal stage: "Preparing". Slave_IO_Running is
now set to "Yes" only when all initializing is done and the IO thread is
ready to read things from the master.
The only test affected by this change is rpl_flsh_tbls, which got stuck in
the preparing phase while trying to read the GTID position from a table.
Fixed by having this test waiting for Preparing instead of Yes.
NOT NULL constraint must be checked *after* the BEFORE triggers.
That is for INSERT and UPDATE statements even NOT NULL fields
must be able to store a NULL temporarily at least while
BEFORE INSERT/UPDATE triggers are running.
The bug was caused by accessing uninitialized fields within the LEX related to
ssl by mysql_show_grants() -> get_current_user() -> has_auth() function.
