160bbb70ee MXS-251: strerror 
Replaces all calls to strerror with calls to strerror_r. The former
is non-thread safe while the latter is.

fffd8fb73a Unify DCB close processing to single function dcb_close. Remove dcb_add_to_zombieslist (incorporating logic into dcb_close). Alter logic so that DCB that is just allocated will still go to zombie list if dcb->fd is not closed. 2015-07-07 16:57:12 +01:00

8f570082eb poll.c:poll_add_event_to_dcb didn't update pollStats.evq_pending when added event became pending. That may cause threads to run in poll loop with minimal timeout infinitely. Added counter update. 2014-12-15 22:21:23 +02:00

7fed679f40 poll.c:poll_add_event_to_dcb did not increase the pollStats.evq_pending counter which caused it to go negative, which, inturn caused all threads to spinloop with minimal timeout. 2014-12-15 22:09:23 +02:00

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

fd11e6a7f5 Session-specific logging. Added functions 
void session_enable_log(SESSION* ses, logfile_id_t id)
and
void session_disable_log(SESSION* ses, logfile_id_t id)

Which switch specific log type on/off if the log type in question is not generally enabled.

Each thread carries a thread-specific struct log_info_t which includes members for current session id and bitfield for enabled log types for the current session. That information is checked before actual log write functions are called.

Each file where session-specific logging is used, must include the following exports:

/** Defined in log_manager.cc */
extern int            lm_enabled_logfiles_bitmask;
extern size_t         log_ses_count[];
extern __thread log_info_t tls_log_info;

60536f622e Fix to bug #590, http://bugs.mariadb.com/show_bug.cgi?id=590 
Added function poll.c:poll_add_epollin_event_to_dcb which adds given event and related GWBUF to given DCB. The DCB is then added to event queue list so that its even becomes executed as soon as any of the threads start to process events next time.
The problem solved is case where COM_CHANGE_USER failed due to authentication failure. An error should be sent to the client but it was sent once per failed backend authentication instead of just once.
Thread which failed in authentication bypassed router and thus replies weren't filtered out. Solution adds an event and a GWBUF including error message to DCB and the DCB is then added to event queue. Thus the error message appeares like it was an incoming event and becomes processed properly.

An addition was made to mysql_backend.c:gw_read_backend_event so that self-generated event can be processed. Even if socket read doesn't manage to read anything, function proceeds if there is enough data in DCB's readqueue.

Fix ti bug #602, http://bugs.mariadb.com/show_bug.cgi?id=602
Added function sescmd_response_complete which checks if the read data completes session command response packet(s). Function is called only if there's a sessoin command being executed.
