This reverts commit c37b2087b4.
In c37b20887, when re-binlogging a GTID event on a replica,
it will overwrite the thread_id from the primary to be the
value of the slave applier (SQL thread or parallel worker).
This should be the value of the original thread_id on the
master connection though, to both help track temporary
tables, and be consistent with Query_log_event.
Reverting the commit to re-target 11.5, so we can re-test
with the corrected thread_id.
enable ssl + ssl_verify_server_cert in the internal client too
* fix replication tests to disable master_ssl_verify_server_cert
because accounts are passwordless - except rpl.rpl_ssl1
* fix federated/federatedx/connect to disable SSL_VERIFY_SERVER_CERT
because they cannot configure an ssl connection
* fix spider to disable ssl_verify_server_cert, if configuration
says so, as spider _can_ configure an ssl connection
* memory leak in embedded test-connect
This patch augments Gtid_log_event with the user thread-id.
In particular that compensates for the loss of this info in
Rows_log_events.
Gtid_log_event::thread_id gets visible in mysqlbinlog output like
#231025 16:21:45 server id 1 end_log_pos 537 CRC32 0x1cf1d963 GTID 0-1-2 ddl thread_id=10
as 64 bit unsigned integer.
While the size of Gtid event has grown by 8-9 bytes
replication from OLD <-> NEW is not affected by it.
This work was started by the late Sujatha Sivakumar.
Brandon Nesterenko took it over, reviewed initial patches and extended
the work.

There are a few different cases to consider
Logging of CREATE TABLE and CREATE TABLE ... LIKE
- If REPLACE is used and there was an existing table, DDL log the drop of
the table.
- If discovery of table is to be done
- DDL LOG create table
else
- DDL log create table (with engine type)
- create the table
- If table was created
- Log entry to binary log with xid
- Mark DDL log completed
Crash recovery:
- If query was in binary log do nothing and exit
- If discoverted table
- Delete the .frm file
-else
- Drop created table and frm file
- If table was dropped, write a DROP TABLE statement in binary log
CREATE TABLE ... SELECT required a little more work as when one is using
statement logging the query is written to the binary log before commit is
done.
This was fixed by adding a DROP TABLE to the binary log during crash
recovery if the ddl log entry was not closed. In this case the binary log
will contain:
CREATE TABLE xxx ... SELECT ....
DROP TABLE xxx;
Other things:
- Added debug_crash_here() functionality to Aria to be able to test
crash in create table between the creation of the .MAI and the .MAD files.
Logging logic:
- Log tables, just before they are dropped, to the ddl log
- After the last table for the statement is dropped, log an xid for the
whole ddl log event
In case of crash:
- Remove first any active DROP TABLE events from the ddl log that matches
xids found in binary log (this mean the drop was successful and was
propery logged).
- Loop over all active DROP TABLE events
- Ensure that the table is completely dropped
- Write a DROP TABLE entry to the binary log with the dropped tables.
Other things:
- Added code to ha_drop_table() to be able to tell the difference if
a get_new_handler() failed because of out-of-memory or because the
handler refused/was not able to create a a handler. This was needed
to get sequences to work as sequences needs a share object to be passed
to get_new_handler()
- TC_LOG_BINLOG::recover() was changed to always collect Xid's from the
binary log and always call ddl_log_close_binlogged_events(). This was
needed to be able to collect DROP TABLE events with embedded Xid's
(used by ddl log).
- Added a new variable "$grep_script" to binlog filter to be able to find
only rows that matches a regexp.
- Had to adjust some test that changed because drop statements are a bit
larger in the binary log than before (as we have to store the xid)
Other things:
- MDEV-25588 Atomic DDL: Binlog query event written upon recovery is corrupt
fixed (in the original commit).
- created binlog_encryption test suite and added it to the default list
- moved some tests from rpl, binlog and multisource suites to extra
so that they could be re-used in different suites
- made minor changes in include files
1. use include/show_binlog_events.inc instead of SHOW BINLOG EVENTS
2. use include/show_relaylog_eventc.inc too
3. in all other places where a number might appear in the result
file, include binlog_start_pos.inc, calculate the position
like pos=`select $binlog_start_pos + 100`; and use
replace_result $pos <pos>
