If MaxScale is started without the appropriate permissions to the paths
pointed by default values, the debug assertion fails even though the
parameter is valid but not usable.
The random number generator can be initialized when MaxScale's other
systems are being initialized. This removes the need to initialized it
when the function is used for the first time.
Added a section to the release notes that tells the fact that the
readwritesplit, schemarouter and binlogrouter now also accept the values
of router_options as parameters.
NullFilter is a filter module that does nothing, except reports
capabilities as defined in the configuration file. It's purpose
is only to make it simple to benchmark the performance impact
various routing capabilities have.
Note that since getCapabilities() currently does *not* take an
instance pointer as parameter, all NullFilter instances will
report the same capabilities, the ones specified for the last
filter to have been loaded.
- Add note about filters having become available in 2.1.
- Add insertstream to release notes and change log.
- Add complete example to cache documentation.
Removed unused spinlocks from DCBs, sessions and the MySQL protocol
structs. They were used in a context where only one thread has access to
the structure.
Removed unused member variables from DCBs.
The use of monitors in services isn't complete but this was not in the
documentation. A more complete solution should be done at a later date and
the current documentation should be removed.
The debug assertion assumes that the table definition is always in the
binlogs. If a binlog row event without a table definition is read, debug
versions would crash even though the situation is acceptable and expected.
In a configuration with multiple services, one with connection_timeout and
others without it, the connections to non-connection_timeout services
would get immediately closed due to integer overflow.
The backtick was copied to the field name and converted to an underscore
when the name was transformed into a valid Avro identifier. This caused
one extra character to appear in the field name in the Avro schema files.
As the DCBs are "owned" by threads and are handled without locks, no
cross-thread access to those DCBs should be done. Due to this, the show
persistent command for maxadmin has to be changed to show only the size of
the pool.
For instance, if bob is returned an error because he does not have
the required grants, then if the error were cached, alice would
receive bob's error reply even if she has the required grants.
- snake_case
- member variables prefixed with m_
- static member variables prefixed with s_
- where prefixes are used (z,p,s), the following character
is capitalized
