Fixed string truncation warnings by reducing max parameter lengths by one
where applicable. The binlogrouter filename lengths are slightly different
so using memcpy to work around the warnings is an adequate "solution"
until the root of the problem is solved.
Removed unnecessary CMake policy settings from qc_sqlite. Adding a
self-dependency on the source file of an external project has no effect
and only caused warnings to be logged.
MXS-1545: handling of slave file EOF refactoring.
Some slave/router state are now checked before any WARN/ERROR messages
about slave file EOF.
The missing “next_file” is always logged with warn.
Stop replicating from master if unsupported binlog events are seen.
Also report error message for unsupported events
(blr_read_events_all_events) at maxscale start-up and with
maxbinlogcheck utility
Cleaned up the MaxScale version of the mysql.h header by removing all
unused includes. This revealed a large amount of dependencies on these
removed includes in other files which needed to be fixed.
Also sorted all includes in changed files by type and alphabetical
order. Removed explicit revision history from modified files.
With GTID master registration always get filename from GTID repo.
The filestem option is not written if binlog_name is not set: this is
not needed by GTID registration.
router->fileroot is set when last name is loaded from GTID repo.
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.
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';
Files are saved in GTID repo at creation time: this allows to show
files without transactions via SHOW [FULL] BINARY LOGS
The FULL keywords add domain_id and server id to the output as file
prefix: 0/10122/mysql-bin.000080
Standalone events in transaction (no COMMIT event) are now handled:
the GTID is saved to gtid_maps storage.
Transaction detection assumes there is only one query_event after GTID
event with MARIADB_FL_STANDALONE flag set.
Saving GTID components into gtid_maps storage will allow to create a
hiearchical binlog cache dir.
Empty GTID for master registration can be specified with SET
@@global.gtid_slave_pos = ‘’
MariaDB GTID Master registration:
creating missing binlog files (with 4 byes) between current one and the
filename coming from ROTATE_EVENT.
blr_slave_binlog_dump() is also checking possible empty files.
New option ‘mariadb10_master_gtid’ in use.
Only MariaDB 10 Slaves with GTID request can register if the option is
set.
When receiving a Master reply to a GTID request and the GTID_LIST is
seen, an IGNORABLE event could be written at the end of file if
GTID_LIST next_pos is beyond that EOF
New routine blr_handle_fake_gtid_list added for fake GTID_LIST_EVENT.
blr_file_append O_APPEND is set only if mariadb10_master_gtid is not
set.
blr_file_append() routine could change name in next commits
The “mariadb_gtid” parameter is no longer available:
“mariadb10_slave_gtid” is the new one.
Another parameter “mariadb10_master_gtid” enable GTID registration.
The latter set to On forces option “mariadb10_slave_gtid” to be On
