If the avrorouter is being build and the required libraries are not found,
the configuration process should fail. Adding the command to bypass this
into the error message should make it easier to disable this part if it is
not needed.
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.
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.
According to customer reports collecting the statistics has a significant
impact on the performance. As we don't need that information we can just
as well turn off that.
Further, since maxscale-common now links to the sqlite3-library, no
module needs to do that explicitly.
The warning that a schema already exists is obsolete as mapped tables are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.
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 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.
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.
The avrorouter now uses the parameters from the source service. This
removes the need for redundant parameter definition in the avrorouter
service when they are defined in the binlogrouter service as parameters.
Added some missing configuration sanity checks and updated the tutorial to
reflect the new configuration method introduced in 2.1.
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.
If the binlog has binlog checksums enabled, the extra checksum bytes are
removed from the end of the event. The avrorouter assumes that whatever
caused the binlogs to appear in the first place already checked that the
checksums are OK.
Also removed one extra byte being added to the length of all query events.
The asserted value can be false without it being an error. When a table is
re-mapped to a different position, there is no guarantee that the previous
value has not been reused by another table.
The avrorouter failed to detect ALTER TABLE statements which caused a
regression. Extended the alter table tests to parse the JSON for more
strict validation of test results.
