SLES 15 doesn't have any sort of init functions which is why the error is
converted to a status message. A dummy file that just prints an error is
placed into /etc/init.d/ to make it clear to the users that they should
use systemd to start MaxScale.
The mysqlauth SQLite database is now opened in WAL mode if possible. This
should prevent lockups of the database when the list of users is updated.
Also moved the starting of the SQLite transaction one level up to also
include the delete part in it. This should further reduce the effects of
updating users.
The number of arguments to createListener was incremented but the maximum
count was not. Also fixed the parameter types for createListener and
alterServer.
The server runtime alteration was broken by commit
c850336199c3c19508a3d280fb7000291d66b80c when it increased the maximum
argument count of the `alter server` command to 14.
Servers in MaxScale can encrypt the connections without client keys and
certificates. As keys and certificates are no longer required, the CA
certificate must always be initialized.
When a listener is created at runtime or SSL is being enabled for an
already created listener, the ssl_verify_peer_certificate parameter can
now be defined.
Backported the minimal set of changes required to build 2.1 with GCC
8. The format-truncation and format-overflow warnings are disabled instead
of fixed in 2.1 to remove duplication of effort that was already done in
2.2 (the commit doesn't cherry-pick cleanly).
The default database was not extracted correctly as the length of the
user's name did not include the null terminator. Also the comparison for
database name length used the smaller than operator instead of the correct
larger than operator.
When the connection pool is inspected, both the client username and IP
must match. This causes the pool to be partitioned by username and IP,
prevening unintentional sharing of connections between different users.
Also, the list of release notes have been removed from the upgrading
document. The referral to the ChangeLog remains. That way, the list
of release notes need not be maintained in several places.
The test appears to hang when the `SET sql_log_bin = 0` statement is
executed. Removing this seems to fix it and is OK as that's not what the
test aims to check.
Disabling the session cache prevents errors from being generated as the
default OpenSSL configuration is to enable session caching but with an
uninitialized context ID. In addition to preventing the errors, it
prevents the possible security problems implicated by the definition a
"static" context ID.
ENGINE is a keyword but not a reserved word, so it must
silently convert into an identifier if it is used in a
context where it cannot be used as a keyword.
The test should stop MaxScale when it is fixing the replication to prevent
the triggering of the standalone master detection.
Also removed leading spaces from the messages and fixed a possible crash with a
NULL value given to `ssh_node`.
