The warning that a schema already exists is obsolete as mapped tables are
now always opened instead of being reused. This causes the schema checks
to be done for each mapped table.
When an assertion fails due to an overflow of the event buffer, all
processed values for that event are dumped.
This commit also enables the assertions even for non-debug builds which
should speed up the elimination process for bugs in the avrorouter. The
overhead of doing this is minimal as the output is already gathered for
the INFO level logging.
Make all modules lowercase and make module loading case
insensitive. Further, make command invocation case insensitive,
as far as the module name is conserned.
The `purge` command can be used to reset the conversion
process. Currently, executing the `purge` module command and restarting
MaxScale is the only correct way to reset the conversion process.
Added more debug assertions to JSON serialization of the Avro schema. Also
checked that the column count for the TABLE_CREATE object matches that of
the TABLE_MAP object.
The test loads multiple modules in one call so we have to pre-load them
one by one to make sure that they are all present regardless of the
locations where the individual modules were built.
A subset of the checks done at connection creation time need to be done at
query routing time. This guarantees that the connection is closed if the
server no longer qualifies as a valid candidate.
Added teset case that checks that a change in the replication topology
correctly breaks the connection.
The check for the current master backend did not see if the backend was
actually in use. This would be the case when the backend would be
originally in use but would be later disabled.
The default value for strict_multi_stmt prevents compound statements and
atomic multi-statement commands from being executed without completely
disabling load balancing. As the new default value will have no practical
effect on all correct uses of readwritesplit, this is a relatively safe
thing to change.
As the object name formatting is automated, so should the formatting of
object names in arguments. This also makes 2.2 backwards compatible with
2.1 commands.
The value is now stored as a hexadecimal value instead of a decimal
value. This also lifts the enum size restriction on more than 8 values
(which was incorrectly documented as 255 values).
The fact whether a query explicitly defined a query was ignored by the
statement parsing function and it always assumed the database was
explicitly defined. This caused the TABLE keyword in a CREATE TABLE
statement to be falsely identified as the current database.
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.
MXS-1530: check ANNOTATE_ROWS flag in connecting slave.
In MariaDB 10.2.4 replicate_annotate_row_events and
binlog_annotate_row_events have default to ON: this change checks
whether the connecting slave is not has ANNOTATE_ROWS in
blr_slave_binlog_dump(), those ANNOTATE_ROWS events can be sent or not
to the slave.
When a table map event is read after an alter table, the old TABLE_MAP
object contains old information. Due to this, as well as the added benefit
of making the code easier to read, the recycling of TABLE_MAP objects was
removed. In practice, there were no benefits to re-mapping the tables to a
different ID.
The Annotate_rows events were not processed which caused the following
table map event to be ignored.
Also removed a false debug assertion. The byte count can be zero and the
pointer is not guaranteed to point to anything valid.
If a CREATE TABLE statement had a quoted keyword as the name of a field,
the calculated column count and actual column counts would differ.
In addition to this, oneline comments before the end of the statement
would truncate the SQL due to the fact that the whitespace was squashed
before the comment removal was done.
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
