Denis Chudov updated IGNITE-18351:
----------------------------------
Description:
*Motivation*
Recently, we redesigned the behavior of lock manager, but did not modify the
interface. This leads to the inconsistency between method name and what the
method actually does.
The ticket inspires to improve interface of lock manager to avoid wrong usage
of the interface.
* The lock mode LockMode#NL is used nowhere. It is s candidate for removal.
* The LockManager#release(org.apache.ignite.internal.tx.Lock) accepts lock
object as a parameter, but actually removes all locks of a particular
transaction. It should be redesigned in order to accept transaction id as a
parameter..
* The LockManager#release(UUID, LockKey, LockMode) releases a particular lock
mode on a particular key. It should accept lock object as a parameter.
*Definition of done*
Only two following methods related to release should remain in LockManager
interface:
- release(transactionId) // releases all locks that belong to specified
transaction
- release(lock) // releases specific lock
*Implementation notes:*
Only minor changes will be required in production code outside of lock manager,
as only mentioned methods are really needed.
