I wrote a script to dump all RecoveryUnit states for all Clients in GDB, but it would be better (and I believe faster) to implement this as a proper printer in Python. The most challenging part of doing this manually from the debugger is traversing the Abseil hash set, but there is an existing utility function in our printers that would make this script even easier to implement in Python.
define mongo_dump_txns set $client_set = $arg0->_clients set $capacity = $client_set.capacity_ set $ctrl = $client_set.ctrl_ set $i = 0 while ($i < $capacity) if ($ctrl[$i] >= 0) set $client = (mongo::Client*) *$client_set.slots_[$i] print $client print $client->_desc if ($client->_opCtx != 0) print $client->_opCtx print *(WiredTigerRecoveryUnit*)$client->_opCtx->_recoveryUnit end end set $i = $i + 1 end end
