Debian tests are run in 2017, update the test to
use 2027 as a "future".

Don't compare "field == table->next_number_field" because the field
can be special nullable field copy created by the trigger.
Compare field_index values instead.

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().

increase the thread stack a bit for main.signal_demo3
and sys_vars.max_sp_recursion_depth_func to stop failing

Was:
* LEX_USER::password was storing sometimes
  plaintext password and sometimes password hash
* LEX_USER::auth was storing sometimes password hash and
  sometimes plugin authentication string

Now:
* LEX_USER::pwtext stores the password in plain-text
* LEX_USER::pwhash stores the password hash
* LEX_USER::auth stores the plugin authentication string

as this is used quite often

add /usr/share/pkgconfig to the rpm ignored list

allow more characters in a valid user/group name:
* POSIX allows dashes '-' and dots '.'
* also the name may end with a dollar sign '$'

for our purposes it's enough to allow [-.$] anywhere in the name

different fix. remove old ones, wait for THD to be fully
initialized before continuing with the server startup process.

This reverts commits db2e21bf, 13615c5e, 3f515a09, 70113ee1.

        Now both are generated by the cmake from the
        scripts/maria_add_gis_sp.sql.in

Undo the change in test_if_skip_sort_order() that set ref_key=-1 when
a variant of index_merge is used (was made in fix for MDEV-9021).

It turned out that test_if_cheaper_ordering() call below assumes that
ref_key=-1 means "no index is used", that is, "an inefficient full table
scan is done".
This is not the same as index_merge, index_merge can actually be quite
efficient. So, ref_key=MAX_KEY denotes the fact that some index is used,
not any given index.

Do not include BLOB fields by default.

innodbchecksum: add fclose and handle errors

This reverts commit 727f92fe.

This reverts commit df32495c.

ISO C90 does not allow mixed declarations and code.

Changed code to comply to C90 standard.

In order to get all the input from addr2line we must read in a loop,
until the response is complete. Also, in case that the response is
malformed, we must not end up reading invalid memory.

Due to a hack that has propagated to the maria storage engine, undefined
behaviour would result by bypassing the initialization code of variables
after my_thread_init().

By refactoring the nested logic into a separate function, this problem
is resolved.

Setting read and write methods for the SORT_PARAM struct based on
variable length key is done within a single function.

	sql/slave.cc

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.

MDEV-9359: encryption.create_or_replace fails sporadically in buildbot: failing assertion: mutex->magic_n == MUTEX_MAGIC_N

Make sure that encryption threads mutex is initialized before starting
encryption threads.

Fix process  handle leak in buildbot. GenerateConsoleCtrlEvent sent to non-existing process will add a process handle to this non-existing process to console host process conhost.exe

as it's needed for Cassandra in 10.0.
