@ -26,6 +26,35 @@ DESCRIPTION:
2.2) EQUALS to "NEW NUMBER" for subsequent Tx..." for LAST statement because it does not change anything (updates empty table);
JIRA: CORE-6095
FBTEST: bugs.core_6095
NOTES:
[05-mar-2023] pzotov
1. Additional transaction is started by Garbage Collector when SuperServer is checked.
This transaction starts first so it will be seen as Tx with minimal number in the trace log.
But on some hosts *message* in the trace for this tx can appear *after* common transactions.
In order to force GC transaction appear always as FIRST in the trace log, we launch AUX connection here, see 'con_aux'.
2. In SuperServer mode we have to take in account as minimal user Tx = 3 (see START_TX).
In Classic this tx = 0.
3. Expected outputs:
For Classic and SuperClassic:
Found record with "NEW NUMBER" for subsequent Tx numbers: 1
Found "INIT_" token in "TRA_" record. Tx that is origin of changes: 0 ; Tx that finished now: 1
Found record with "NEW NUMBER" for subsequent Tx numbers: 2
Found "INIT_" token in "TRA_" record. Tx that is origin of changes: 0 ; Tx that finished now: 2
Found record with "NEW NUMBER" for subsequent Tx numbers: 3
Found "INIT_" token in "TRA_" record. Tx that is origin of changes: 0 ; Tx that finished now: 3
Found record with "NEW NUMBER" for subsequent Tx numbers: 3
Found "INIT_" token in "TRA_" record. Tx that is origin of changes: 0 ; Tx that finished now: 3
For SuperServer:
Found record with "NEW NUMBER" for subsequent Tx numbers: 4
Found "INIT_" token in "TRA_" record. Tx that is origin of changes: 3 ; Tx that finished now: 4
Found record with "NEW NUMBER" for subsequent Tx numbers: 5
Found "INIT_" token in "TRA_" record. Tx that is origin of changes: 3 ; Tx that finished now: 5
Found record with "NEW NUMBER" for subsequent Tx numbers: 6
Found "INIT_" token in "TRA_" record. Tx that is origin of changes: 3 ; Tx that finished now: 6
Found record with "NEW NUMBER" for subsequent Tx numbers: 6
Found "INIT_" token in "TRA_" record. Tx that is origin of changes: 3 ; Tx that finished now: 6
4. Checked on 5.0.0.970 SS/CS/SC
