Binlog server: force fake Client DCB close in errorReply. This fixes an
issue when START SLAVE, with new config, is called after a previous one
with errors.
Remove saving/updating GTID repo when maxscale starts.
The repo update slows down the maxscale startup.
The saving was added in order populate GTID repo with current file but
it costs extra time to event validation routine when current binlog has
many events and it has a big size.
MXS-1156: MASTER_CONNECT_RETRY is a new option for CHANGE MASTER TO.
The ‘connect_retry’, ‘master_retry_count’ options are now in use for
both service and
router_options.
MXS-1344: Binlog server reports the real master id in SHOW SLAVE STATUS
| SHOW ALL SLAVES STATUS, no matter the value of ‘master_id’ identity
parameter.
Binlog server report its own server id or the identity value of
‘master_id’ in MySQL monitor query SELECT @@global.server_id,
@@read_only;
Note: SELECT @@global.server_id (no other fields) still reports the
real master server id or the value set in ‘master_id’
The internal connections of the binlogrouter should be closed in the same
thread that created them. This should be the "main" thread, i.e. thread 0,
that starts the original binlogrouter service.
Routine blr_handle_missing_files() is called by
blr_handle_fake_rotate().
Field ‘filestem’ is updated in order to avoid wrong file name creation.
Additionally router is not creating any missing filenames if
router->binlog_name is empty (no previous binlog files)
A new option ‘slave_hostname’ allows the setting of hostname in
COM_REGISTER_SLAVE.
SHOW SLAVES HOSTS; in master server can show the hostname set in binlog
router:
MariaDB [(none)]> SHOW SLAVE HOSTS;
+-----------+-----------------------------+------+-----------+
| Server_id | Host | Port | Master_id |
+-----------+-----------------------------+------+-----------+
| 93 | maxscale-blr-1.mydomain.net | 8808 | 10124 |
+-----------+-----------------------------+------+-----------+
PURGE BINARY LOGS; deletes all files in binlogdir and GTID maps repo
but keeps current binlog file.
PURGE BINARY LOGS TO ‘file’; deletes all files in binlogdir and GTID
maps repo up to specified file.
mariadb10_slave_gtid=On option is needed in order to keep the list of
binlog files.
If option ‘binlog_structure’ is set to ‘tree’ then SHOW BINARY LOGS
displays the tree details of the binlog files.
MySQL [(none)]> SHOW BINARY LOGS;
+--------------------------+-----------+
| Log_name | File_size |
+--------------------------+-----------+
| 0/10122/mysql-bin.000117 | 1167 |
| 0/10122/mysql-bin.000118 | 652 |
| 0/10124/foo-bin.000016 | 5082 |
| 0/10124/foo-bin.000017 | 491 |
+--------------------------+-----------+
With option set to ‘flat’ (which is the default) the output contains
only
names:
MySQL [(none)]> SHOW BINARY LOGS;
+------------------+-----------+
| Log_name | File_size |
+------------------+-----------+
| mysql-bin.000110 | 425 |
| mysql-bin.000111 | 10409 |
| mysql-bin.000112 | 9659 |
+------------------+-----------+
SHOW [FULL] BINARY LOGS is now able to report the same filename in use
with different server_ids: this can happen with binlog_structure=tree
example from SHOW FULL BINARY LOGS
0/10122/mysql-bin.000113
…
0/10122/mysql-bin.000116
…
0/5306/mysql-bin.000113
SHOW BINARY LOGS shows the same file twice:
mysql-bin.000113
…
mysql-bin.000116
…
mysql-bin.000113
Add Slave_pos for Using_Gtid in SHOW SLAVE STATUS only if Master GTID
mode is set
Possible output values are:
Default
Using_gtid: No
or
Using_gtid: Slave_pos
Added FAKE_ROTATE event info log.
Changed: log of Request file and pos only if the binlog_name is not
empty (it can be empty when setting the GTID value before CHANGE MASTER
TO)
A call to strcpy was made in blr_file_create where the function was given
the same pointer as both parameters. To avoid this, the file name is now
copied to a local variable before the router variables are modified.
The EVP_CIPHER_CTX is now created inside a wrapper function to add support
for OpenSSL 1.1. Also fixed improper use of the EVP_CIPHER_CTX internals
in binlogrouter.

MXS-1266:
blr_slave_gtid_request() the file in slave registration request is
checked whether it exists or not and GTID file info could e set instead.
Also addded:
blr_handle_simple_select_stmt(): only mariadb10_gtid_domain is checked
for SELECT @@GLOBAL.gtid_domain_id slave request
blr_start_master_registration(): only router->mariadb10_compat is
checked before sending SELECT @@GLOBAL.gtid_domain_id to master
blr_file_create calls mxs_mkdir_all()
MASTER_USE_GTID=Slave_pos is now handled by CHANGE MASTER TO
If mariadb10_master_gtid is On
MASTER_LOG_FILE is no longer required, only MASTER_USE_GTID=Slave_pos
Slave_pos must be set before to empty value or request value:
set @@global.gtid_slave_pos = '0-10116-194';
