ISSUE: 7304
|
||||
TITLE: Events in system attachments (like garbage collector) are not traced
|
||||
DESCRIPTION:
|
||||
Test changes sweep interval to some low value (see SWEEP_GAP) and runs TX_COUNT transactions which
|
||||
lead difference between OST and OIT to exceed given sweep interval. These transactions are performed
|
||||
by ISQL which is launched as child process. SQL script uses table with record that is locked at the
|
||||
beginning of script and execute block with loop of TX_COUNT statements which insert new records.
|
||||
After this loop finish, we make ISQL to hang by forcing it to update first record (see LOCKED_ROW).
|
||||
Then we change DB state to full shutdown and wait until ISQL will be terminated.
|
||||
At this point database has sweep gap that is enough to run auto sweep at first connection to DB.
|
||||
Finally, we bring DB online and start trace with log_sweep = true and log_transactions = true.
|
||||
Doing connection and wait about 2..3 seconds cause auto sweep to be started and completed.
|
||||
This must be reflected in the trace.
|
||||
|
||||
If ServerMode = 'Super' and ParallelWorkers >= 2 and MaxParallelWorkers >= ParallelWorkers
|
||||
then trace log will contain folloing five lines related to worker(s) activity:
|
||||
<TIMESTAMP> (...) START_TRANSACTION
|
||||
<DBFILE> (ATT_..., <Worker>, NONE, <internal>) --------------------- [ 1 ]
|
||||
(TRA_..., READ_COMMITTED | REC_VERSION | WAIT | READ_ONLY)
|
||||
<TIMESTAMP> (...) COMMIT_TRANSACTION
|
||||
<DBFILE> (ATT_..., <Worker>, NONE, <internal>) --------------------- [ 2 ]
|
||||
|
||||
This is the only difference that can be observed for snapshots before and after fix
|
||||
(i.e. BEFORE fix trace had no such lines but all other data about sweep *did* present).
|
||||
Test checks that trace log contains TWO lines with '<worker>', see above [ 1 ] and [ 2 ].

NOTES:

[07.11.2024] pzotov
|
||||
Confirmed absense of lines marked as '<worker' in the trace log for snapshot 5.0.0.731 (15.09.2022).
|
||||
Checked on 5.0.0.733 (16.09.2022); 5.0.2.1553, 6.0.0.515
