Browse Source 
in slave SQL thread: if a transaction fails because of InnoDB deadlock or innodb_lock_wait_timeout exceeded,
optionally retry the transaction a certain number of times (new variable --slave_transaction_retries).


sql/mysql_priv.h:
  new var slave_transaction_retries
sql/mysqld.cc:
  new variable slave_transaction_retries. Plus fixing a typo.
sql/set_var.cc:
  new global variable slave_transaction_retries (will be one per subslave, when we have multimaster).
sql/slave.cc:
  Slave SQL thread: if a transaction fails because of InnoDB deadlock or innodb_lock_wait_timeout exceeded,
  optionally retry the transaction a certain number of times (--slave_transaction_retries).
sql/slave.h:
  new RELAY_LOG_INFO::trans_retries.
