- Start 4 threads where each thread sits in a loop and performs
20% updates and 80% selects. Each thread has a table of its own.
- The main thread executes the following in a loop.
- Perform a switchover from the current master to the next (which is
simply the next node % all nodes).
- Keep on doing that for 1.5 minutes.
The expectation is that the switchover will succeed, that is, after the
operation there will be a new master.
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The warning that a schema already exists is obsolete as mapped tables are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.
- Start 4 threads where each thread sits in a loop and performs
20% updates and 80% selects. Each thread has a table of its own.
- The main thread executes the following in a loop.
- Take down the current master and wait a while (failover assumed
to happen).
- Put up the old master node and wait a while.
Keep on doing that for 1.5 minutes.
At the end check that:
- There is one 'Master'.
- The other nodes are either
- 'Slave' or
- 'Running' in which case it is checked it is because the node could
not be rejoined.
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.
Using commas instead of spaces prevents a the misinterpretation of
commands as hostnames. If the `--hosts` option was given just before a
command, it would consume the commands as arguments to the `--hosts` list.
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.
If node00 is not the master when a test is started, the cleanup
performed by TestConnections takes considerable time.
By restoring the sitation back to normal before ending the test,
the startup time of the next test can be shortened significantly.
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.
