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.
The `add user` and `enable account` commands create fully privileged
administrative users like they did in 2.1. This makes the addition of
read-only users backwards compatible.
Updated and expanded the documentation on administrative interface
users. Added entries into the release notes as well as the upgrading
document about relevant changes between 2.1 and 2.2.
Routine blr_handle_missing_files() is called by
blr_handle_fake_rotate().
Field ‘filestem’ is updated in order to avoid wrong file name creation.
Additionally router is not creating any missing filenames if
router->binlog_name is empty (no previous binlog files)
Removing the last admin account is now forbidden. This should prevent most
cases where users could lock themselves out of the administrative
interface.
This change does allow a non-root network user to be the last admin
account. In practice this does not prevent the root user from gaining
access to maxadmin. Access can be gained by removing the users file and
restarting MaxScale or by editing the users file by hand.
The type of the created user can now be specified with the --type option.
Expanded tests that cover the user creation. Also added a test case that
checks that basic users are only allowed to read through the REST API.
