Reconfigure misuse of cfg versus raw_cfg

    • Type: Icon: Task Task
    • Resolution: Done
    • WT2.4.0
    • Affects Version/s: None
    • Component/s: None

      I hit this while testing WT-1170 with wtperf and a configuration that happened to set compact=true. I had put checkpoint=(wait=10) in my conn_config. By using compact, wtperf calls reconfigure. Calling reconfigure, with async=(enabled=false), means that checkpoints get turned off!

      The reason is that *conn_reconfigure has two configure string arrays, cfg and raw_cfg. Since the call to *wt_checkpoint_server_create takes cfg, it contains the default config plus turns off async. The default config turns off the checkpoint server wait=0 and my checkpoints were not running.

      Half the calls in __conn_reconfigure use cfg and half use raw_cfg. All uses of cfg in there should be investigated.
