This allows an LMDB database to be used as the blockchain to export.
Adjust SOURCE_DB in src/blockchain_converter/blockchain_export.h
depending on needs. Defaults to DB_MEMORY.
DB_MEMORY is a sensible default for users migrating to LMDB, as it
allows the exporter to use the in-memory blockchain while the other
binaries work with LMDB, without recompiling anything.
Add support to:
- BlockchainDB, BlockchainLMDB
- blockchain_import utility to open LMDB database with one or more
LMDB flags.
Sample use:
$ blockchain_import --database lmdb#nosync
$ blockchain_import --database lmdb#nosync,nometasync
This imports to the blockchain database from an exported blockchain
file.
It can be used to bootstrap a new database or to add blocks to an
existing one.
Supports:
- both the in-memory and LMDB implementations
- optional: batching, verification, testnet
See help for usage.

src/cryptonote_core/bootfileloader.{h,cpp}
Add log level support.
Add testnet support.
Add command-line options:
--help
--data-dir
--testnet-data-dir
--testnet
--log-level
--batch
--batch-size
--block-number
See help for usage. Run at log level 1 to see profiling stats.
In order to make things more general, BlockchainDB now has get_db_name()
which should return a string with the "name" of that type of db.
This "name" will be the subfolder name that holds that db type's files
within the monero folder.
Small bugfix: blockchain_converter was not correctly appending this in
the prior hard-coded-string implementation of the subfolder data
directory concept.
Forgot that CMake vars set to PARENT_SCOPE will still vanish if that
parent scope goes...out of scope. LMDB vars elevated one more scope to
compensate for moving db_drivers/ into external/
Ostensibly janitorial work, but should be more relevant later down the
line. Things that depend on core cryptonote things (i.e.
cryptonote_core) don't necessarily depend on BlockchainDB and thus
have no need to have BlockchainDB baked in with them.
Add support to BlockchainDB and BlockchainLMDB for batch transactions.
Add profiling to block and tx processing and DB operations.
Improve block and tx processing efficiency by less repeat hashing.
Move LMDB storage to "lmdb" subfolder.
- Upon startup, if old LMDB files are detected, abort with a message for the user to move them to subfolder or delete them.
Update and fix log statements and formatting.

Usage:
default is lmdb for blockchain branch:
$ make release
same as:
$ DATABASE=lmdb make release
for original in-memory implementation:
$ DATABASE=memory make release
COMMITS:
- Add compile-time support for both db implementations: in-memory and LMDB
NOTE:
The default should be changed to lmdb when this is merged upstream
unless we're 100% sure the LMDB implementation is ready.
Usage:

$ make release
