Several block-redirect related bugfixes. check-in: a56a334333 user: dan tags: block-redirects

Add tests for block-redirects to lsmtest. check-in: eec16b0f2f user: dan tags: block-redirects
16:53
If a free-list-only segment is generated while a merge of the top-level segment is underway, add the new segment to the merge inputs immediately. Also, if auto-checkpoints are enabled, schedule a checkpoint after each block is moved within an lsm_work(nmerge=1) call. check-in: 89b4286682 user: dan tags: block-redirects

              the system recovers and other clients proceed unaffected if
              a process fails in the middle of a write transaction.

              The difference from lsmtest2.c is that this file tests
              live-recovery (recovery from a failure that occurs while other
              clients are still running) whereas lsmtest2.c tests recovery
              from a system or power failure.

  lsmtest9.c: More data tests. These focus on testing that calling
              lsm_work(nMerge=1) to compact the database does not corrupt it.
              In other words, that databases containing block-redirects
              can be read and written.
