ac97fcd764 Removed redundancy from error and message logs. 
server.c: Added new member to SERVER->master_err_is_logged. It is used if server loses master status. It causes error log print in readwritesplit router's eror handling. Initial value is false and it is set always to false when server's status is set to master.
Added message log printing to mysql monitor, if master status changes to something else. It is not warning or error but only information which probably interests the user.

readwritesplit.c:Muted warnings and error printings in cases if slaves are not found if it is allowed to have a master only.
readwritesplit.c:Corrected error log printing in case where master lost its status. REdundant prints are removed.

e6fca9b50d Added a simple test for dbshard router. 
The test sets a session variable and queries a union of this variable and a value in each of the databases.

4dd6f1b9c0 Added comment to assertion regarding to bref->bref_pending_cmd which is a one-slot buffer for database query. If sessoin command cursor is active when query is routed, instead of routing the query to backend it is stored to bref_pending_cmd to wait until previous (session) command is completed. The assertion traps if there is a command already in the bref_pending_cmd. 
Situation is wrong because client shouldn't send new query before the previous (the pending one) is executed in backend and the reply is sent to the client.

a4968f2521 Complete fix candidate for #645, http://bugs.skysql.com/show_bug.cgi?id=645 and #648, http://bugs.skysql.com/show_bug.cgi?id=648 
tee.c:closeSession removed unnecessary dcb_free, router/service closes all backend DCBs and the client DCB, and client DCB is the one that was tried to free in closeSession.
readwritesplit.c:routeQuery now handles untyped and typed GWBUFs. Untyped means that read buffer may consist of incomplete and multiple MySQL packets. Typed buffer always consists of a single MySQL packet (which can be split to many buffers inside GWBUF).
Fixed Coverity cases #84840 and #84841

a91845b324 Re-enabled the ignore list, it uses the parameter 'ignore databases=<list of db names>'.

c31f971999 Fix candidate for #645, http://bugs.skysql.com/show_bug.cgi?id=645 and #648, http://bugs.skysql.com/show_bug.cgi?id=648 
If readwritesplit.c:routeQuery gets a GWBUF whose type is UNDEFINED, then each MySQL packet is extracted from input buffer and passed to new function, route_single_stmt. Each extracted packet is stored in separate GWBUF and added types GWBUF_TYPE_MYSQL and GWBUG_TYPE_SINGLE_STMT which makes it possible to execute session commands and process reply packets properly.

Code nedes still cleaning but this is for testing atm.

cf40cbfbf0 Aadded some of the code from routeQuery to its own function, change_current_db, which extracts db name, tests if the name can be found among cached database names (hashtable) and if it does, change the db. Otherwise create an error message and add it to poll eventqueue like it was sent from some of the backends. 2014-12-08 23:37:21 +02:00
