There was a workaround for linking to boost at all on MINGW, but
unfortunately this workaround would not correctly link to boost
statically. This workaround for that workaround works around the issue
that that workaround had.
Because of some github fuckery I had to manually cherry-pick/rebase
fluffypony's 32- and 64-bit lmdb changes, hence this isn't actually a
merge commit.
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.
Everything except actually *using* BlockchainBDB is wired up, but the db
itself is not yet working. Some error about user mem not large enough.
I think I know what this error means, but I can't determine the cause.
Notes: BerkeleyDB does not allow 0-indexing in its recno type databases,
so block numbers *in the database* will be 1-indexed. Modifications
to indexing have been made as needed.
LMDB implementation code copy/paste/modified into the Berkeley DB
implementation. Need to test if it builds, then if it works, and so on,
but the code is all there.
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.
Based on work by tomerkon.
See https://github.com/tomerkon
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.
