|
* @file pgsql-transaction_state_comprehensive-t.cpp
|
|
* @brief Comprehensive TAP test for transaction state manager in all scenarios.
|
|
*
|
|
* Tests all critical paths identified in code audit:
|
|
* 1. Normal transaction flow (BEGIN -> COMMIT/ROLLBACK)
|
|
* 2. Transaction with errors (aborted transaction)
|
|
* 3. Pipeline mode transactions
|
|
* 4. Connection pool return during transaction
|
|
* 5. locked_on_hostgroup scenario
|
|
* 6. Fast-forward mode
|
|
* 7. Mirror sessions
|
|
* 8. Savepoint operations
|
|
* 9. Variable snapshots in transactions
|
|
* 10. Error recovery and state consistency
