Michael, there's a trivial bug in txn.c:wt_txn_update_oldest, and I'm not sure enough of what's going on to just fix it. In this code:
/* Update the oldest ID. */
if (WT_TXNID_LT(prev_oldest_id, oldest_id) || last_running_moved) {
/*
* We know we want to update. Check if we're racing.
*/
...
} else {
if (WT_VERBOSE_ISSET(session, WT_VERB_TRANSACTION) &&
current_id - oldest_id > 10000 && last_running_moved &&
oldest_session != NULL) {
(void)__wt_verbose(session, WT_VERB_TRANSACTION,
"old snapshot %" PRIu64
" pinned in session %d [%s]"
" with snap_min %" PRIu64 "\n",
oldest_id, oldest_session->id,
oldest_session->lastop,
oldest_session->txn.snap_min);
}
WT_ASSERT(session, txn_global->scan_count > 0);
(void)__wt_atomic_subiv32(&txn_global->scan_count, 1);
}
The test for the verbose message can't ever fire because if last_running_moved was set, then we would have taken the previous code clause instead.
