In some cases you might want to use a specific address/interface
when connecting to a server instead of the default one. With the
global parameter 'local_address' it can now be specified which
address to use.
The token skipping function did not check for a period or an opening
parenthesis when parsing the test. Also fixed a debug assertion when only
NULL values were inserted.
Used the correct value in table_create_alloc and remove unused
parameter. Use the pre-calculated end pointer when looking for events.
Always use the column count of the TABLE_MAP event as all mismatches are
detected earlier.
DATETIME values in old formats should always be 8 bytes long. This is how
MariaDB 10.2 stores them and only DATETIME2 values are stored with a
fractional part.
The parser checks whether the FIRST or AFTER keywords are used and, if
AFTER is used, extracts the relevant column name.
Added a test case that checks that the parsing works and detects the
correct column names.
The list of users that is used for authentication shoudl only consist of
users that do not use an explicit authentication plugin. This way
authentication fails before any connections to the backend servers are
done.
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The warning that a schema already exists is obsolete as mapped tables are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.
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.
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.
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.
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.
When the unit tests were run without installing the libraries in their
final locations, the loading of the modules would fail. Using locations
relative to the build directory allows unit testing without having to
install the libraries.
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 trailing comment removal pattern unnecessarily required that a leading
space is present in all trailing comments.
Also, the pattern didn't match if no line ending was included in the SQL
statement. The subject ending should be the third valid terminator in
addition to UNIX and Windows style line endings.
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 backend DCBs didn't have a valid service pointer whereas the client
DCBs had one. The necessity of the pointer can be questioned as a similar
pointer is located in the session.
The service for a dummy session will be NULL. If authentication fails for
a dummy session, then no service level actions should be taken.
Only the binlogrouter can trigger authentication failure with a dummy
session as it creates connections before the service itself has started.
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.
The readqueue should never be explicitly assigned and should only ever be
appended to. This guarantees that the packets are read and processed in
the correct order.
Also removed an unused function that deals with the readqueue
manipulation.
When packets were routed individually, the qualification for the
persistent pool was done before the current command was updated. In
addition to this, the previous commit doesn't seem like it can even build.
