This replaces the epee and data_loggers logging systems with
a single one, and also adds filename:line and explicit severity
levels. Categories may be defined, and logging severity set
by category (or set of categories). epee style 0-4 log level
maps to a sensible severity configuration. Log files now also
rotate when reaching 100 MB.
To select which logs to output, use the MONERO_LOGS environment
variable, with a comma separated list of categories (globs are
supported), with their requested severity level after a colon.
If a log matches more than one such setting, the last one in
the configuration string applies. A few examples:
This one is (mostly) silent, only outputting fatal errors:
MONERO_LOGS=*:FATAL
This one is very verbose:
MONERO_LOGS=*:TRACE
This one is totally silent (logwise):
MONERO_LOGS=""
This one outputs all errors and warnings, except for the
"verify" category, which prints just fatal errors (the verify
category is used for logs about incoming transactions and
blocks, and it is expected that some/many will fail to verify,
hence we don't want the spam):
MONERO_LOGS=*:WARNING,verify:FATAL
Log levels are, in decreasing order of priority:
FATAL, ERROR, WARNING, INFO, DEBUG, TRACE
Subcategories may be added using prefixes and globs. This
example will output net.p2p logs at the TRACE level, but all
other net* logs only at INFO:
MONERO_LOGS=*:ERROR,net*:INFO,net.p2p:TRACE
Logs which are intended for the user (which Monero was using
a lot through epee, but really isn't a nice way to go things)
should use the "global" category. There are a few helper macros
for using this category, eg: MGINFO("this shows up by default")
or MGINFO_RED("this is red"), to try to keep a similar look
and feel for now.
Existing epee log macros still exist, and map to the new log
levels, but since they're used as a "user facing" UI element
as much as a logging system, they often don't map well to log
severities (ie, a log level 0 log may be an error, or may be
something we want the user to see, such as an important info).
In those cases, I tried to use the new macros. In other cases,
I left the existing macros in. When modifying logs, it is
probably best to switch to the new macros with explicit levels.
The --log-level options and set_log commands now also accept
category settings, in addition to the epee style log levels.

Monero Blockchain Utilities
Copyright (c) 2014-2016, The Monero Project
Introduction
The blockchain utilities allow one to import and export the blockchain.
Usage:
See also each utility's "--help" option.
Export an existing blockchain database
$ monero-blockchain-export
This loads the existing blockchain and exports it to $MONERO_DATA_DIR/export/blockchain.raw
Import the exported file
$ monero-blockchain-import
This imports blocks from $MONERO_DATA_DIR/export/blockchain.raw (exported using the
monero-blockchain-export tool as described above) into the current database.
Defaults: --batch on, --batch size 20000, --verify on
Batch size refers to number of blocks and can be adjusted for performance based on available RAM.
Verification should only be turned off if importing from a trusted blockchain.
If you encounter an error like "resizing not supported in batch mode", you can just re-run
the monero-blockchain-import command again, and it will restart from where it left off.
## use default settings to import blockchain.raw into database
$ monero-blockchain-import
## fast import with large batch size, database mode "fastest", verification off
$ monero-blockchain-import --batch-size 20000 --database lmdb#fastest --verify off
Import options
--input-file
specifies input file path for importing
default: <data-dir>/export/blockchain.raw
--output-file
specifies output file path to export to
default: <data-dir>/export/blockchain.raw
--block-stop
stop at block number
--database <database type>
--database <database type>#<flag(s)>
database type: lmdb, memory
flags:
The flag after the # is interpreted as a composite mode/flag if there's only one (no comma separated arguments).
The composite mode represents multiple DB flags and support different database types:
safe, fast, fastest
Database-specific flags can be set instead.
LMDB flags (more than one may be specified):
nosync, nometasync, writemap, mapasync, nordahead
Examples:
$ monero-blockchain-import --database lmdb#fastest
$ monero-blockchain-import --database lmdb#nosync
$ monero-blockchain-import --database lmdb#nosync,nometasync
