A \n encounted in a string given to the query classifier test
program compare, is not converted into a newline. Makes it easier
to debug problems related to newlines.
When a statement like 'DESCRIBE tbl' is classified, the table
name will now be available so that a router can check whether the
table is a temporary one. In that case, the statement must be sent
to the master.
In this mode the compare program does a sanity check where it compares the
output of a classifier when a statement is classified multiple times. The
main use-case for this is to get the verbose output generated when the -v3
option is added, not the sanity check itself.
A statement like
SELECT ... INTO OUTFILE|DUMPFILE ...
is now classified as a QUERY_TYPE_WRITE, instead of as
QUERY_TYPE_GSYSVAR_WRITE so that it will be sent only to the
master.
See script directory for method. The script to run in the top level
MaxScale directory is called maxscale-uncrustify.sh, which uses
another script, list-src, from the same directory (so you need to set
your PATH). The uncrustify version was 0.66.
qc_thread_init() must now explicitly be called in every thread
and not just in other threads but the one where qc_process_init()
is called.
This change was caused by QC_INIT_SELF initialization actually
being performed in query_classifier.cc. Before this change, there
actually was a leak in the routing worker running in the main
thread, the query classification cache was created twice.
Removed skygw_utils and relate files along with the old log manager
code. Also removed file flushing due to it being redundant; messages are
written to the file immediately. Adjusted tests to accommodate this
change.
Now takes a structure that, if present, enables the query
classification caching and specifies the properties of the
cache.
For the time being no actual properties are yet available.
