If the session id is known, it will be logged together with all
messages. If present, the session id appears, enclosed in paranthesis,
right after the message category. E.g.
2017-08-30 12:20:49 warning: (4711) [masking] The rule ...
This will be used by a subsequent `session_get_current()` and
`session_get_current_id()` for obtaining the current SESSION and
session id, respectively. The latter of those will be used by the
logging mechanism for logging the session id in conjunction with
messages.
When dcb_close() is called, the DCB is only marked for closing
and the actual closing takes place only after all event handlers
have been called. That way, the state of the DCB will not change
during event processing but only after.
From a handler perspective this should now be just like it was
when the zombie queue was present.
TODO: There are far too many state variables or variables akin to
state variables - dcb_role, state, persistentstart, n_close -
in DCB. A cleanup is warranted.
The EOF packet calculation function in modutil.cc didn't handle the case
where the payload exceeded maximum packet size and could mistake binary
data for a ERR packet.
The state of a multi-packet payload is now exposed by the
modutil_count_signal_packets function. This allows proper handling of
large multi-packet payloads.
Added minor improvements to mxs1110_16mb to handle testing of this change.
As each client/server connection will be handled by a specific
thread, all closing activity can take place directly when the
connection is closed and not later when the zombie queue is
processed.
In a subsequent commit the zombie queue will be removed.
The default users are now inserted into the admin users files if no
existing files are found. This removes the hard-coded checks for admin
user names and simplifies the admin user logic.
The default interface for the admin interface is the IPv6 address '::'
which corresponds to the IPv4 address '0.0.0.0'. If the system doesn't
support IPv6, then an attempt to bind on IPv4 should be made.
The uses_function type rule matches when any of the columns given as
values uses a function. With this, columns can be denied from being used
with a function.
If MaxScale Binlog Server is detected by MySQL monitor, then Server
status is ‘Relay Master, Running’ without ‘Slave’: this way Binlog
Server cannot be used by any statement routing.
Additionally SELECT for replication lag is skipped as well.
MXS-1344: Binlog server reports the real master id in SHOW SLAVE STATUS
| SHOW ALL SLAVES STATUS, no matter the value of ‘master_id’ identity
parameter.
Binlog server report its own server id or the identity value of
‘master_id’ in MySQL monitor query SELECT @@global.server_id,
@@read_only;
Note: SELECT @@global.server_id (no other fields) still reports the
real master server id or the value set in ‘master_id’
In qc_sqlite the fields that a particular function refers to are now
collected and reported. Qc_mysqlembedded needs to be updated accordingly
and also the compare utility. For subsequent commits.
The internal connections of the binlogrouter should be closed in the same
thread that created them. This should be the "main" thread, i.e. thread 0,
that starts the original binlogrouter service.
