DECIMAL types that were larger than 8 bytes were not handled
correctly. The current implementation only prints the lowest 8 bytes of
the integer part of the decimal.
The warning that a schema already exists is obsolete as mapped tables are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.
Updated links and module names in the configuration. Also changed object
names so that they don't produce warnings. Removed redundant parameters
and tuned default monitor_interval to a slightly more reasonable 2000
milliseconds. Enabled automatic thread number configuration.
The output generated by a failed call to a module command was previously
overwritten with the error messages stored in the module command
subsystem.
In the case of a failure, the proper procedure is to check if the output
generated by the module command conforms to the JSON API error
specification and if it does, combine it with any system generated error
messages. If the output does not conform, it is stored in the "meta" field
of the returned object. This allows all of the generated output to be
saved.
Only asynchronous authenticators require the thread-specific loading of
users as the synchronous ones all share the same data. If the service does
not declare asynchronous capabilities at startup, the users are not
seeded. This prevents unnecessary loading of users at startup.
Time elapsed is now properly tracked during a switchover. After slave
redirection, an event is added to the master. Then, the slaves are queried
repeatedly until they advance to the newest event. I/O and SQL errors are
also detected.
Setting the query classifier with an absolute path makes it easier to
manage test setup without having to manually resolve the relative path to
the query classifier from the test source directory.
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.
The query classifier was not initialized for the housekeeper thread. This
means that tasks could not use the query classifier and as the avro
conversion is done inside a task, it can't use it.
As the stale status is not a real status bit and it's used to retain the
history of a master, there is no need to print it in any output. This
output will only confuse users now that the stale status will not be
cleared from masters that go down.
The log manager could send two messages if a log message was posted soon
before the log manager was stopped. This caused a debug assertion which
then manifested as a deadlock inside the log manager.
Make all modules lowercase and make module loading case
insensitive. Further, make command invocation case insensitive,
as far as the module name is conserned.
During switchover, MASTER_GTID_WAIT is now called on all slaves. This causes
switchover to complete slower than before but is safer if log_slave_updates
is not on on the new master server. Also, read_only is disabled on the
demoted server if waiting on slaves or promotion fails. This should
effectively cancel the failover for the old master.
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.
All modules now have an 8-bit range for capability flags. Currently only
the client side authenticator and protocol capability bits are loaded due
to the fact that backend versions of these modules don't relate to a
particular service.
