Project: Firebird Core
Issue Type: Bug
Components: Engine
Affects Versions: 3.0.3, 3.0.2, 3.0.1, 3.0.0
Reporter: Vlad Khorsun
First sweep run:
Sweep is started by SYSDBA
Database "S:\TEMP\TX.30.FDB"
OIT 4294965022, OAT 4294985533, OST 4294985533, Next 4294985533

Database "S:\TEMP\TX.30.FDB"
OIT 18238, OAT 4294985533, OST 4294985533, Next 4294985534
Run sweep again
Sweep is started by SYSDBA
Database "S:\TEMP\TX.30.FDB"
OIT 4294965022, OAT 4294985534, OST 4294985534, Next 4294985534
Sweep is finished
Database "S:\TEMP\TX.30.FDB"
OIT 18239, OAT 4294985534, OST 4294985534, Next 4294985535
Note:
- OIT is less than 2^32 (4'294'965'022 < 4'294'967'296), while Next is greater
than 2^32 (4'294'985'534 > 4'294'967'296)
- OIT is the same at both "Sweep is started" message , i.e. it was not moved by
sweep
- "Sweep is finished" message contains wrong OIT value (truncated to 32-bit
number)
