      [FAB-2351] Update loggers to flogging.MustGetLogger · 7132dd54
      Will Lahti authored
      
      
      This CR updates all loggers throughout the code base to use
      `flogging.MustGetLogger`. This function wraps `logging.MustGetLogger`
      and tracks the logger modules defined in the system. This enables the
      ability to set log levels for modules using regular expressions.
      and make it easy to change the levels for any module and all its
      submodules with a single command (e.g. gossip, ledger, msp).

      https://jira.hyperledger.org/browse/FAB-2022
      
      
      
      This changes introduced by this CR
      - Moves the block storage code from package
      core/ledger/blkstorage to common/ledger/blkstorage
      
      - Splits the ledger_interface.go so as to move common interfaces
      and data type to common/ledger package
      
      - Moves some of the util functions to common/ledger package
      
      - Moves core/ledger/ordererledger package to orderer/ledger/fsledger
      orderer folks can futher rename/refactor this as seems suitable to them

      SingleLevelDB for block index · 8cdd0f4d
      manish authored
      https://jira.hyperledger.org/browse/FAB-1664
      
      
      
      This changeset:
      - Renames package ledger/util/db to ledger/util/leveldbhelper
      - Implements a leveldb provider
        (that enables using same leveldb instance as a multiple logical dbs)
        in util package for being able to reuse across statedb, index,
        and later for historydb
      - Implements a provider as a single point of invocation
        for managing multiple block storage
      - Uses a single leveldb instance for block storage index
      - Makes the structures other than providers as private
        to their respective packages

      Disable WAL for block storage DB · 0df6a8d1
      manish authored
      
      
      (Rocks) DB WAL adds overheads while using the DB for saving checkpoints
      for block storage. Avoiding writing to WAL translates the write workload
      (appending blocks to the blockfile) into a sequential disk writes.
      
      This commit changes the way checkpoints are saved - checkpoints are
      written to DB as before, however since WAL is disabled, the checkpoint
      stays in-memory only. The in-memory checkpoint is flushed explicitly to
      disk (via DB flush) at the time of new block file creation. The in-memory
      checkpoint would implicitly also be flushed to memory at the time of DB
      shutdown. However, if a crash takes place, the checkpoint available in the
      DB would be behind the actual block file status. In order to handle this
      crash scenario, this commit also adds code to perform a scan of the block
      file beyond the last saved checkpoint and update the checkpoint.
