- Changed replaying to always allocate a separate THD object
for applying log events. This is to avoid tampering original
THD state during replay process.
- Return success from sp_instr_stmt::exec_core() if replaying
succeeds.
- Do not push warnings/errors into diagnostics area if the
transaction must be replayed. This is to avoid reporting
transient errors to the client.
Added two tests galera_sp_bf_abort, galera_sp_insert_parallel.
Wsrep-lib position updated.
Wsrep-lib is now guaranteed to hold the underlying mutex
which is wrapped in lock object passed to Wsrep_client_service
interrupted() call. The library part will now take care of
checking the wsrep::transaction specific state, so it is
enough to check the thd->killed state for the result.
The replayer did not signal replaying waiters. Added
mysql_cond_broadcast() after replaying is over.
Assertion on client error failed after replay attempt failed due
to certification failure. At this point the transaction does not
go through client state, so the client error cannot be overridden.
Assign ER_LOCK_DEADLOCK to thd directly instead.
Use timed cond wait when waiting for replayers to finish and
check if the transaction has been BF aborted during the wait.
Make sure that the Annotate_rows_log_events is written into
binlog only for the first fragment of the current statement.
Also avoid flusing pending rows event when calculating bytes
generated by the transaction.
Added and recorded a test which verifies that the binlog
contains only one Annotate_rows_log_event per statement
with various SR settings. Recrded mysql-wsrep-features#136
which produced different output with excession log events
suppressed.
