What is changed and how it works?
TestWriteReorgForColumnTypeChangeOnAmendTxn
begins an explicit pessimistic transaction and locks some keys. But it does not close the session at the end of the test. So thettlManager
keeps updating TTL for the transaction, leading to a goroutine leak.This PR closes the session at the end of the test.
