      Description

      While playing around with the fine-grained-durability branch and the txn test, I ran 'wt printlog' on one of the database home dirs and that took an assertion failure.

      %  ./wt -h WT_TEST/test_txn02.1 printlog
      [
        { "lsn" : [1,128],
          "type" : 3,
          "txnid" : 1,
      archive-server: ../src/os_posix/os_remove.c, 35: fh == NULL
      archive-server: aborting WiredTiger library
      ...
      

      Here's the stack:

      (gdb) bt

      WT-10 0x00007fff95f4b1e1 in thread_start ()
      

      Clearly the wt printlog has the log file open as it reads the log.

      I think the fix is that wt should disable archiving when it opens the connection.
