- High priority interface method to apply NBO begin, separate from
apply_toi() in order to avoid implementation to force interpreting
ws_meta flags.
- Method to put client_state into NBO mode when applying NBO begin.
The client_state will process in m_local mode.
- Unit tests for applying NBO
* Add method `restore_prepared_transaction` to `client_state` class
which restores a transaction state from storage given its xid.
* Add method `commit_or_rollback_by_xid` to terminate prepared XA
transactions by xid.
* Make sure that transactions in prepared state are not rolled back
when their master fails/partitions away.
- populate and pass real error description buffer to provider in case
of applying error
- return 0 from server_state::on_apply() if error voting confirmed
consistency
- remove fragments and rollback after fragment applying failure
- always release streaming applier on commit or rollback
Inherited db::replayer_service from db::high_priority_service
and overrode after_apply() and is_replaying() methods to match
current state of library implementation. Changed
db::client_service::replay() to use db::replayer_service instead
of db::high_priority_service().
The empty implementation of log_dummy_write_set() in dbsim
high priority service implementation left unreleased commit
order critical section behind whenever remote write set failed
certification. Added calls to do empty commit to release the
critical section.
Other:
Implemented ostream operator<< for wsrep:🧵:id, and added
printout of owning thread into transaction debug output.
* Enable codepath to BF abort high priority SR applier
* Pass ws_handle, ws_meta to high priority service rollback
call to allow total ordering of rollback process
The write set handle and meta data are needed for SR transactions
where the commit context is not known when the transaction starts.
The passed handle and meta data can be set through client_state
prepare_for_ordering() call before performing commit.
