Added support for X/Open XA prepare, recover, commit and rollback.
innobase/include/trx0roll.h:
Changed prototype of the function trx_rollback_or_clean_all_without_sess
because this function is executed in a background thread.
innobase/include/trx0trx.h:
Added support for X/Open XA prepare, recover and search by X/Open XA XID.
innobase/include/trx0undo.h:
Added support for X/Open XA prepare and recover. We need to store X/Open XA XID
to the undo log header for recovery.
innobase/log/log0recv.c:
Create a thread to run trx_rollback_or_clean_all_without_sess function
to rollback the uncommitted transactions which have no user session.
innobase/row/row0ins.c:
Remove unnecessary variables.
innobase/trx/trx0roll.c:
Changed so that trx_rollback_or_clean_all_without_sess is executed
in a background thread. We should also leave all prepared transactions
active to wait for commit or abort from MySQL.
innobase/trx/trx0sys.c:
Only those rows which belong to the active transaction in crash recovery
are undone.
innobase/trx/trx0trx.c:
Added support for X/Open XA prepare and recover. We need to store X/Open XA
XID to trx structure and left prepared transactions to wait for a
commit or abort from MySQL. This requires also that we add TRX_PREPARED
state to the transaction and TRX_UNDO_PREPARED state for undo logs.
innobase/trx/trx0undo.c:
Added support for X/Open XA prepare and recover. We need to store X/Open XA
XID to undo log header for recovery of distributed transactions.
sql/ha_innodb.h:
Added prototypes for X/Open XA prepare, recover, commit and rollback.
sql/handler.h:
Added definition for X/Open XA XID structure.
