"INTERVAL N <unit>" is now handled as an expression in itself and
as asuch will cause both statements such as
"SELECT '2008-12-31 23:59:59' + INTERVAL 1 SECOND;"
and
"select id from db2.t1 where DATE_ADD("2017-06-15", INTERVAL 10 DAY) < "2017-06-15";"
to be handled correctly. The compare test program contains some
heuristic checking, as the the embedded parser will in all cases
report date manipulation as the use of the add_date_interval()
function.
After a temporary table is created, readwritesplit will check whether a
query drops or targets that temporary table. The check for query type was
missing from the table dropping part of the code. The temporary table read
part was checking that the query is a text form query.
Added a debug assertion to the query parsing function in qc_sqlite to
catch this type of interface misuse.
MySQLAuth requires the SHOW DATABASES privilege to see all the databases
so it should be checked that the current user has the permission. A
missing permission will cause errors that are hard to resolve.
When the IO thread of a relay master is stopped, the knowledge that it is
not a real master but a relay master is lost. To prevent this loss of
information, the master server's server_id value should always be stored
if it is available.
If a server is removed from a service, readconnroute will not verify that
the server it is connected to is still the same root master. This fixes
the regression of MXS-1418.
When auto_failover has been disabled due to failure to perform automatic
failover, the test should reset the number of failures. Resetting it
before the check for the log message allows the test to still fail if the
message is missing.
Test that `list servers` works with both monitored and unmonitored
servers. The test doesn't check that the GTID is present as the test setup
uses file and position based replication.
When TSV output is requested, the output should not contain the ANSI color
codes. This appears to be a "feature" of the table generation library but
it is quite simple to work around.
When the servers were iterated, each related monitor was requested. This
caused as many requests for monitors as there are servers.
By creating a set of unique monitor names and requesting them once, we
avoid the redundant requests from the monitor.
The function getResource had two different implementations that did very
different things. The newer version, that returns the raw JSON object that
represents a resource, was renamed to getJson.
Added the `GTID` field to make it easier to track GTID values of the
servers. This is done by requesting the related monitors for each server
and injecting an extra parameter into the server resource.
When the parsing of a query failed, the message would treat the parameter
as a string as the printf format was `%*s` instead of `%.*s`.
The manpage of printf states the following about the precision specifier:
... or the maximum number of characters to be printed from a string
for `s` and `S` conversions.
This means that the field length specifier is somewhat meaningless for
strings.
The output of `show threads` could have a negative historic thread load
average that could be explained by the overflow of the signed 32-bit
integer used to count the number of samples.
The time that each thread started to process an event for a DCB used an
old value that is no longer used. Updating this to DCB::last_read retains
the 2.0 behavior.
According to MXS-1644 the refreshing of users may cause a crash.
In that particular case, the refreshing is triggered by the
authentication failing due to the user having hit the
'max_user_connection' limit of the server.
That is, refreshing the users in the situation is never going to
change the end-result. With this change, the users will not be
refreshed in that case and hopefully the crash will be avoided.
Note that this is something of a workaround as the crash could not
be repeated and the refreshing of the users should obviously not
ever cause MaxScale to crash.
Listed changes to MaxCtrl and the CDC connnector to release notes. Added a
note into the upgrade document about the beta versions of the MaxCtrl
client.
Placed the CDC Connector documentation in the main documentation directory
under the Connector directory. Added a link into the
Documentation-Contents.md document.
