causal_reads does not work with servers that update their state via
mechanisms other than the standard replication. In practice this is just
another Galera limitation.
The SQL for the second recursive CTE table can be optimized by adding a
where condition on the recursive part that rules out users that are not
roles. The functionality remains the same as only roles can be granted to
users.
Checking presence of 'apt', 'yum' or 'zypper' command is not very
reliable way to determine package manager type.
E.g. OpenSUSE 25 has 'apt' which is wrapper over 'zypper' or rpm tools
can be installed on Ubuntu.
More relible way is to check /etc/*-release file and if it is not
availabe try to check presence of apt, yum or zypper
Added new ssl_version value for TLSv1.3. This allows the list of accepted
protocol versions to be limited to all supported protocols. Previously
TLSv1.3 was only available with ssl_version=MAX.
Also fixed the enum value serialization to use a lowercase v. This causes
them to have the same value as the one used in the enum.
Previously when ssl_version was used with a value that is not supported on
the system, an unknown parameter error was returned. This could be
confusing and logging a proper error message should make it clear.
1) Only two backends are set up for extra-port
2) The setting is checked to work by connecting directly to servers
3) The server connections are saturated before starting MaxScale
4) MaxScale logs are checked for extra-port-related messages
In the tokenizer we will now recognize the character set names
of MariaDB and return a specific token for those. However, where
a character set name is not expected, it will automatically be
treated as an identifier.
Note that when the character set name is explicitly specified
for a literal string, the name must be prefixed with an underscore.
That is, if the character set name is "latin1", when used when
specifying a literal string, it's used as "_latin1 'a'".
Note that this does not fix the sqlite3 bug causing a leak, but
since the statement will now correctly be parsed, the leak will
not manifest itself.
The mkopcodeh.tcl of sqlite3 version 3110100 has a bug that
manifests itself so that it generates broken code depending on
what keywords there are and in what order. The mkopcodeh.tcl
from 3200000 does not have that problem.
Originally, the sqlite installation was imported into the MaxScale
repository in the one gigantic MaxScale 1.4 -> 2.0 commit.
Consequently, there is no import commit to compare to if you want
to extract all MaxScale specific changes. To make it simpler in the
future, sqlite will now be imported in a commit of its own.
So as to allow the change date to be update at each maintenance
release, we need to have a separate license for each minor release.
In each minor branch there will then be a LICENCE.TXT symbolic link
that points to the actual file.
Generated the new MaxCtrl documentation with the new help output. The help
output now doesn't auto-wrap which causes lines to be longer but it
prevents broken Markdown formatting. It also makes it more readable on
wider terminals.
The number of sessions wasn't always incremented but it was always
decremented. This happened primarily when authentication failed. By making
the management of the counters a part of the object lifecycle, this
problem goes away.
