- If everything in the first buffer of a buffer chain is consumed,
then the whole chain and not just the first buffer was freed.
NOTE: gwbuf_rtrim needs to be fixed so that it removes data from the
tail of a chain and *not* from the end of the first buffer in
a chain. That cannot ever be what is wanted.
Previously, MaxAdmin would interpret any non-option words in the
command line as either a filename or, if the file could not be opened,
as MaxAdmin commands. This made it possible to mix filenames and
commands if there was a matching filename in the folder. For example
"maxadmin show services" would read commands from a file named
"show services" if it existed. This update removes this feature. To
read commands from a file, use either shell redirection "maxadmin <
mycommands" or the "source"-command inside maxadmin.
General code cleanup. Routing error detection now more robust.
Remove some unused code. Debug messages now use "unique_name" when
referring to servers.
Supports hint types:
-master
-slave
-named server
-all
A default action, which is performed when no hint exists or on error,
can be set. The different actions are analogous to the hint types.
A maximum connection number for slaves can be set. If more slaves are
configured for the service, the filter will rotate slaves for new sessions.
Within a session with multiple slaves, the "route_to_slave"-hint will
also rotate among the slave backends.
The readwritesplit now sends COM_PING queries to backend servers that have
been idle for too long. The option is configured with the
`connection_keepalive` parameter.
The contents of the existing filter.cc was copied into filter.c that
subsequently was renamed to filter.cc.
The way the session is called as the last filter in the filter chain
is really dubious and ought to be rearranged so that the blind casting
of a session to a filter and back is not needed.
