.TH MDB_COPY 1 "2014/06/20" "LMDB 0.9.14"
.\" Copyright 2012-2014 Howard Chu, Symas Corp. All Rights Reserved.
.\" Copying restrictions apply. See COPYRIGHT/LICENSE.
.SH NAME
mdb_copy \- LMDB environment copy tool
.SH SYNOPSIS
.B mdb_copy
[\c
.BR \-V ]
[\c
.BR \-c ]
[\c
.BR \-n ]
.B srcpath
[\c
.BR dstpath ]
.SH DESCRIPTION
The
.B mdb_copy
utility copies an LMDB environment. The environment can
be copied regardless of whether it is currently in use.
No lockfile is created, since it gets recreated at need.
If
.I dstpath
is specified it must be the path of an empty directory
for storing the backup. Otherwise, the backup will be
written to stdout.
.SH OPTIONS
.TP
.BR \-V
Write the library version number to the standard output, and exit.
.TP
.BR \-c
Compact while copying. Only current data pages will be copied; freed
or unused pages will be omitted from the copy. This option will
slow down the backup process as it is more CPU-intensive.
.TP
.BR \-n
Open LDMB environment(s) which do not use subdirectories.
.SH DIAGNOSTICS
Exit status is zero if no errors occur.
Errors result in a non-zero exit status and
a diagnostic message being written to standard error.
.SH CAVEATS
This utility can trigger significant file size growth if run
in parallel with write transactions, because pages which they
free during copying cannot be reused until the copy is done.
.SH "SEE ALSO"
.BR mdb_stat (1)

mdb_dump \- LMDB environment export tool

.B mdb_dump
.BR \ envpath

.BR \-V ]
[\c

[\c

.SH DESCRIPTION
The
.B mdb_dump
utility reads a database and writes its contents to the
standard output using a portable flat-text format
understood by the
.BR mdb_load (1)
utility.
.SH OPTIONS
.TP
.BR \-V
Write the library version number to the standard output, and exit.
.TP
.BR \-f \ file
Write to the specified file instead of to the standard output.
.TP
.BR \-l
List the databases stored in the environment. Just the
names will be listed, no data will be output.
.TP
.BR \-n
Dump an LMDB database which does not use subdirectories.
.TP
.BR \-p
If characters in either the key or data items are printing characters (as
defined by isprint(3)), output them directly. This option permits users to
use standard text editors and tools to modify the contents of databases.
Note: different systems may have different notions about what characters
are considered printing characters, and databases dumped in this manner may
be less portable to external systems.
.TP
.BR \-a
Dump all of the subdatabases in the environment.
.TP
.BR \-s \ subdb
Dump a specific subdatabase. If no database is specified, only the main database is dumped.
.SH DIAGNOSTICS
Exit status is zero if no errors occur.
Errors result in a non-zero exit status and
a diagnostic message being written to standard error.
Dumping and reloading databases that use user-defined comparison functions
will result in new databases that use the default comparison functions.
\fBIn this case it is quite likely that the reloaded database will be
damaged beyond repair permitting neither record storage nor retrieval.\fP
The only available workaround is to modify the source for the
.BR mdb_load (1)
utility to load the database using the correct comparison functions.

.TH MDB_LOAD 1 "2014/06/20" "LMDB 0.9.14"

.SH NAME
mdb_load \- LMDB environment import tool
.SH SYNOPSIS
.B mdb_load
.BR \ envpath
[\c
.BR \-V ]
[\c
.BI \-f \ file\fR]
[\c
.BR \-n ]
[\c
.BI \-s \ subdb\fR]
[\c
.BR \-N ]
[\c
.BR \-T ]
.SH DESCRIPTION
The
.B mdb_load
utility reads from the standard input and loads it into the
LMDB environment
.BR envpath .
The input to
.B mdb_load
must be in the output format specified by the
.BR mdb_dump (1)
utility or as specified by the
.B -T
option below.
.SH OPTIONS
.TP
.BR \-V
Write the library version number to the standard output, and exit.
.TP
.BR \-f \ file
Read from the specified file instead of from the standard input.
.TP
.BR \-n
Load an LMDB database which does not use subdirectories.
.TP
.BR \-s \ subdb
Load a specific subdatabase. If no database is specified, data is loaded into the main database.
.TP
.BR \-N
Don't overwrite existing records when loading into an already existing database; just skip them.
.TP
.BR \-T
Load data from simple text files. The input must be paired lines of text, where the first
line of the pair is the key item, and the second line of the pair is its corresponding
data item.
A simple escape mechanism, where newline and backslash (\\) characters are special, is
applied to the text input. Newline characters are interpreted as record separators.
Backslash characters in the text will be interpreted in one of two ways: If the backslash
character precedes another backslash character, the pair will be interpreted as a literal
backslash. If the backslash character precedes any other character, the two characters
following the backslash will be interpreted as a hexadecimal specification of a single
character; for example, \\0a is a newline character in the ASCII character set.
For this reason, any backslash or newline characters that naturally occur in the text
input must be escaped to avoid misinterpretation by
.BR mdb_load .
.SH DIAGNOSTICS
Exit status is zero if no errors occur.
Errors result in a non-zero exit status and
a diagnostic message being written to standard error.

If \fB\-fff\fP is given, display the full list of page IDs in the freelist.
.TP
.BR \-n
Display the status of an LMDB database which does not use subdirectories.
.TP
.BR \-r
Display information about the environment reader table.
Shows the process ID, thread ID, and transaction ID for each active
reader slot. The process ID and transaction ID are in decimal, the
thread ID is in hexadecimal. The transaction ID is displayed as "-"
if the reader does not currently have a read transaction open.
If \fB\-rr\fP is given, check for stale entries in the reader
table and clear them. The reader table will be printed again
after the check is performed.
.TP
.BR \-a
Display the status of all of the subdatabases in the environment.
.TP
.BR \-s \ subdb
Display the status of a specific subdatabase.
.SH DIAGNOSTICS
Exit status is zero if no errors occur.
Errors result in a non-zero exit status and
a diagnostic message being written to standard error.

.TH MDB_COPY 1 "2014/06/20" "LMDB 0.9.14"
.\" Copyright 2012-2014 Howard Chu, Symas Corp. All Rights Reserved.
.\" Copying restrictions apply. See COPYRIGHT/LICENSE.
.SH NAME
mdb_copy \- LMDB environment copy tool
.SH SYNOPSIS
.B mdb_copy
[\c
.BR \-V ]
[\c
.BR \-c ]
[\c
.BR \-n ]
.B srcpath
[\c
.BR dstpath ]
.SH DESCRIPTION
The
.B mdb_copy
utility copies an LMDB environment. The environment can
be copied regardless of whether it is currently in use.
No lockfile is created, since it gets recreated at need.
If
.I dstpath
is specified it must be the path of an empty directory
for storing the backup. Otherwise, the backup will be
written to stdout.
.SH OPTIONS
.TP
.BR \-V
Write the library version number to the standard output, and exit.
.TP
.BR \-c
Compact while copying. Only current data pages will be copied; freed
or unused pages will be omitted from the copy. This option will
slow down the backup process as it is more CPU-intensive.
.TP
.BR \-n
Open LDMB environment(s) which do not use subdirectories.
.SH DIAGNOSTICS
Exit status is zero if no errors occur.
Errors result in a non-zero exit status and
a diagnostic message being written to standard error.
.SH CAVEATS
This utility can trigger significant file size growth if run
in parallel with write transactions, because pages which they
free during copying cannot be reused until the copy is done.
.SH "SEE ALSO"
.BR mdb_stat (1)

.SH NAME
mdb_dump \- LMDB environment export tool
.SH SYNOPSIS
.B mdb_dump
.BR \ envpath
[\c
.BR \-V ]
[\c
.BI \-f \ file\fR]
[\c
.BR \-l ]
[\c
.BR \-n ]
[\c
.BR \-p ]
[\c
.BR \-a \ |
.BI \-s \ subdb\fR]
.SH DESCRIPTION
The
.B mdb_dump
utility reads a database and writes its contents to the
standard output using a portable flat-text format
understood by the
.BR mdb_load (1)
utility.
.SH OPTIONS
.TP
.BR \-V
Write the library version number to the standard output, and exit.
.TP
.BR \-f \ file
Write to the specified file instead of to the standard output.
.TP
.BR \-l
List the databases stored in the environment. Just the
names will be listed, no data will be output.
.TP
.BR \-n
Dump an LMDB database which does not use subdirectories.
.TP
.BR \-p
If characters in either the key or data items are printing characters (as
defined by isprint(3)), output them directly. This option permits users to
use standard text editors and tools to modify the contents of databases.
Note: different systems may have different notions about what characters
are considered printing characters, and databases dumped in this manner may
be less portable to external systems.
.TP
.BR \-a
Dump all of the subdatabases in the environment.
.TP
.BR \-s \ subdb
Dump a specific subdatabase. If no database is specified, only the main database is dumped.
.SH DIAGNOSTICS
Exit status is zero if no errors occur.
Errors result in a non-zero exit status and
a diagnostic message being written to standard error.
Dumping and reloading databases that use user-defined comparison functions
will result in new databases that use the default comparison functions.
\fBIn this case it is quite likely that the reloaded database will be
damaged beyond repair permitting neither record storage nor retrieval.\fP
The only available workaround is to modify the source for the
.BR mdb_load (1)
utility to load the database using the correct comparison functions.

.SH NAME
mdb_load \- LMDB environment import tool
.SH SYNOPSIS
.B mdb_load
.BR \ envpath
[\c
.BR \-V ]
[\c
.BI \-f \ file\fR]
[\c
.BR \-n ]
[\c
.BI \-s \ subdb\fR]
[\c
.BR \-N ]
[\c
.BR \-T ]
.SH DESCRIPTION
The
.B mdb_load
utility reads from the standard input and loads it into the
LMDB environment
.BR envpath .
The input to
.B mdb_load
must be in the output format specified by the
.BR mdb_dump (1)
utility or as specified by the
.B -T
option below.
.SH OPTIONS
.TP
.BR \-V
Write the library version number to the standard output, and exit.
.TP
.BR \-f \ file
Read from the specified file instead of from the standard input.
.TP
.BR \-n
Load an LMDB database which does not use subdirectories.
.TP
.BR \-s \ subdb
Load a specific subdatabase. If no database is specified, data is loaded into the main database.
.TP
.BR \-N
Don't overwrite existing records when loading into an already existing database; just skip them.
.TP
.BR \-T
Load data from simple text files. The input must be paired lines of text, where the first
line of the pair is the key item, and the second line of the pair is its corresponding
data item.
A simple escape mechanism, where newline and backslash (\\) characters are special, is
applied to the text input. Newline characters are interpreted as record separators.
Backslash characters in the text will be interpreted in one of two ways: If the backslash
character precedes another backslash character, the pair will be interpreted as a literal
backslash. If the backslash character precedes any other character, the two characters
following the backslash will be interpreted as a hexadecimal specification of a single
character; for example, \\0a is a newline character in the ASCII character set.
For this reason, any backslash or newline characters that naturally occur in the text
input must be escaped to avoid misinterpretation by
.BR mdb_load .
.SH DIAGNOSTICS
Exit status is zero if no errors occur.
Errors result in a non-zero exit status and
a diagnostic message being written to standard error.

.SH NAME
mdb_stat \- LMDB environment status tool
.SH SYNOPSIS
.B mdb_stat
.BR \ envpath
[\c
.BR \-V ]
[\c
.BR \-e ]
[\c
.BR \-f [ f [ f ]]]
[\c
.BR \-n ]
[\c
.BR \-r [ r ]]
[\c
.BR \-a \ |
.BI \-s \ subdb\fR]
.SH DESCRIPTION
The
.B mdb_stat
utility displays the status of an LMDB environment.
.SH OPTIONS
.TP
.BR \-V
Write the library version number to the standard output, and exit.
.TP
.BR \-e
Display information about the database environment.
.TP
.BR \-f
Display information about the environment freelist.
If \fB\-ff\fP is given, summarize each freelist entry.
If \fB\-fff\fP is given, display the full list of page IDs in the freelist.
.TP
.BR \-n
Display the status of an LMDB database which does not use subdirectories.
.TP
.BR \-r
Display information about the environment reader table.
Shows the process ID, thread ID, and transaction ID for each active
reader slot. The process ID and transaction ID are in decimal, the
thread ID is in hexadecimal. The transaction ID is displayed as "-"
if the reader does not currently have a read transaction open.
If \fB\-rr\fP is given, check for stale entries in the reader
table and clear them. The reader table will be printed again
after the check is performed.
.TP
.BR \-a
Display the status of all of the subdatabases in the environment.
.TP
.BR \-s \ subdb
Display the status of a specific subdatabase.
.SH DIAGNOSTICS
Exit status is zero if no errors occur.
Errors result in a non-zero exit status and
a diagnostic message being written to standard error.

For importing into the LMDB database, compile with `DATABASE=lmdb`
e.g.
`DATABASE=lmdb make release`
This is also the default compile setting on the blockchain branch.
By default, the exporter will use the original in-memory database (blockchain.bin) as its source.
This default is to make migrating to an LMDB database easy, without having to recompile anything.
To change the source, adjust `SOURCE_DB` in `src/blockchain_converter/blockchain_export.h` according to the comments.
# Usage:
See also each utility's "--help" option.
## Export an existing in-memory database
`$ blockchain_export`
This loads the existing blockchain, for whichever database type it was compiled for, and exports it to `$MONERO_DATA_DIR/export/blockchain.raw`
## Import the exported file
`$ blockchain_import`
This imports blocks from `$MONERO_DATA_DIR/export/blockchain.raw` 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.
```bash
# use default settings to import blockchain.raw into database
$ blockchain_import
# fast import with large batch size, verification off
$ blockchain_import --batch-size 100000 --verify off
# LMDB flags can be set by appending them to the database type:
# flags: nosync, nometasync, writemap, mapasync
$ blockchain_import --database lmdb#nosync
$ blockchain_import --database lmdb#nosync,nometasync
```
## Blockchain converter with batching
`blockchain_converter` has also been updated and includes batching for faster writes. However, on lower RAM systems, this will be slower than using the exporter and importer utilities. The converter needs to keep the blockchain in memory for the duration of the conversion, like the original bitmonerod, thus leaving less memory available to the destination database to operate.
```bash
$ blockchain_converter --batch on --batch-size 20000
```

/* DB Driver Interface
*
* The DB interface is a store for the canonical block chain.
* It serves as a persistent storage for the blockchain.
*
* For the sake of efficiency, the reference implementation will also
* store some blockchain data outside of the blocks, such as spent
* transfer key images, unspent transaction outputs, etc.
*
* Transactions are duplicated so that we don't have to fetch a whole block
* in order to fetch a transaction from that block. If this is deemed
* unnecessary later, this can change.
*
* Spent key images are duplicated outside of the blocks so it is quick
* to verify an output hasn't already been spent
*
* Unspent transaction outputs are duplicated to quickly gather random
* outputs to use for mixins
*
* IMPORTANT:
* A concrete implementation of this interface should populate these
* duplicated members! It is possible to have a partial implementation
* of this interface call to private members of the interface to be added
* later that will then populate as needed.
*
* General:
* open()
* is_open()
* close()
* sync()
* reset()
*
* Lock and unlock provided for reorg externally, and for block
* additions internally, this way threaded reads are completely fine
* unless the blockchain is changing.
* bool lock()
* unlock()
*
* vector<str> get_filenames()
*
* Blocks:
* bool block_exists(hash)
* height add_block(block, block_size, cumulative_difficulty, coins_generated, transactions)
* block get_block(hash)
* height get_block_height(hash)
* header get_block_header(hash)
* block get_block_from_height(height)
* size_t get_block_size(height)
* difficulty get_block_cumulative_difficulty(height)

* uint64_t get_top_block_timestamp()
* hash get_block_hash_from_height(height)
* blocks get_blocks_range(height1, height2)
* hashes get_hashes_range(height1, height2)
* hash top_block_hash()
* block get_top_block()
* height height()
* void pop_block(block&, tx_list&)
*
* Transactions:
* bool tx_exists(hash)
* uint64_t get_tx_unlock_time(hash)
* tx get_tx(hash)
* uint64_t get_tx_count()
* tx_list get_tx_list(hash_list)
* height get_tx_block_height(hash)
*
* Outputs:
* index get_random_output(amount)
* uint64_t get_num_outputs(amount)
* pub_key get_output_key(amount, index)
* tx_out get_output(tx_hash, index)
* hash,index get_output_tx_and_index_from_global(index)
