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.
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.
The type and name parsing functions could move outside of allocated memory
as they didn't check for the terminating null character. Also fixed the
printf format string used when the list of used tables is being created.
Fixed CDC testing connector to abort on error and added some extra output
to the cdc_datatypes test.
When log messages are written with both address and port information, IPv6
addresses can cause confusion if the normal address:port formatting is
used. The RFC 3986 suggests that all IPv6 addresses are expressed as a
bracket enclosed address optionally followed by the port that is separate
from the address by a colon.
In practice, the "all interfaces" address and port number 3306 can be
written in IPv4 numbers-and-dots notation as 0.0.0.0:3306 and in IPv6
notation as [::]:3306. Using the latter format in log messages keeps the
output consistent with all types of addresses.
The details of the standard can be found at the following addresses:
https://www.ietf.org/rfc/rfc3986.txthttps://www.rfc-editor.org/std/std66.txt
Both the listeners and servers now support IPv6 addresses.
The namedserverfilter does not yet use the new structures and needs to be
fixed in a following commit.
There's no point in indexing the file if it hasn't been synced to
disk. Any attempts to index the file will fail if the file still has an
open data block.
The debug assertion assumes that the table definition is always in the
binlogs. If a binlog row event without a table definition is read, debug
versions would crash even though the situation is acceptable and expected.
Moved some typedefs to router.h and server.h, changed a few
constants to these enums. Renamed some types in config.h to
remove "Gateway".
There are still some functions in the public header which are
only used in core, but they seem to fit the theme of public functions
so were not moved.
