Add public method blockchain_storage::debug_pop_block_from_blockchain()
Ensure blockchain_import calls destructors before exit.
To test:
DATABASE=memory make release
// create blockchain.bin from blockchain.raw if needed
build/release/bin/blockchain_import --block-stop 1000
// try popping a single block
build/release/bin/blockchain_import --pop-blocks 1
Some filesystems (*cough* NTFS *cough*) aren't good with sparse files,
so this makes LMDB dynamically resize its mapsize as needed. Note: the
check interval is currently every 10 blocks (for testing) and will
probably need to change to 1000 or something. Default mapsize set to
1GiB.
Blockchain conversion tools using batching will probably segfault, I'll
fix that in the next commit.
Remove repeated coinbase tx in each exported block's data.
Add resume from last exported height to blockchain_export, making it the
default behavior when the file already exists.
Start reorganizing the utilities.
Various cleanup.
Update output, including referring to both height and block numbers as
zero-based instead of one-based. This better matches the block data,
rather than just some parts of the existing codebase.
Use smaller default batch sizes for importer when verifying, so progress
is saved more frequently.
Use small default batch size (1000) for importer on Windows, due to
current issue with big transaction sizes on LMDB.

Due to a bug in unbound, we were passing a string containing a null
character to ub_ctx_resolvconf and ub_ctx_hosts rather than a NULL
pointer. On *nix this wasn't causing headache, but on Windows this was
causing unbound to not correctly load DNS settings from the OS.
Note on the bug: in a Windows-specific code branch in the function
ub_ctx_hosts(), if the hosts file specified was a NULL pointer, a call
to getenv() was stored in a local char* and later freed. This is
incorrect, as we do not own that data, and caused the program to crash.
Daemon interactive mode is now working again.
RPC mapped calls in daemon and wallet have both had connection_context
removed as an argument as that argument was not being used anywhere.
b43716c Do store transaction's blob size in transaction_chain_entry (Sergey Kazenyuk)
3be518f Use single get_transaction_hash to get both id and blob size (Sergey Kazenyuk)
There will need to be some more refactoring for these changes to be
considered complete/correct, but for now it's working.
new daemon cli argument "--db-type", works for LMDB and BerkeleyDB.
A good deal of refactoring is also present in this commit, namely
Blockchain no longer instantiates BlockchainDB, but rather is passed a
pointer to an already-instantiated BlockchainDB on init().
DNSSEC is now implemented with the hardcoded key from unbound.
This will need to be not hardcoded in the future, but is okay for now.
Unit tests updated for DNSSEC (as well as for the fact that, contrary to
previous assumption, example.com does not have a static IP address).
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.
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.

Fixed the windows path, and improved logging and data
(for graph) logging, fixed some locks and added more checks.
Still there is a locking error,
not added by my patches, but present in master version
(locking of map/list of peers).
This was changed because sometimes the daemon does not complete its exit
routine with this method, but as it does correctly wind most things down
even if it gets stuck I've changed it back.
The RPC calls the daemon executable uses to talk to the running daemon
instance have mostly been added back in. Rate limiting has not been
added in upstream, but is on its way in a separate effort, so those
calls are still NOPed out.
many RPC functions added by the daemonize changes
(and related changes on the upstream dev branch that were not merged)
were commented out (apart from return). Other than that, this *should*
work...at any rate, it builds, and that's something.
new update of the pr with network limits
more debug options:
discarding downloaded blocks all or after given height.
trying to trigger the locking errors.
debug levels polished/tuned to sane values.
debug/logging improved.
warning: this pr should be correct code, but it could make
an existing (in master version) locking error appear more often.
it's a race on the list (map) of peers, e.g. between closing/deleting
them versus working on them in net-limit sleep in sending chunk.
the bug is not in this code/this pr, but in the master version.
the locking problem of master will be fixed in other pr.
problem is ub, and in practice is seems to usually cause program abort
(tested on debian stable with updated gcc). see --help for option
to add sleep to trigger the error faster.
Update of the PR with network limits
works very well for all speeds
(but remember that low download speed can stop upload
because we then slow down downloading of blockchain
requests too)
more debug options
fixed pedantic warnings in our code
should work again on Mac OS X and FreeBSD
fixed warning about size_t
tested on Debian, Ubuntu, Windows(testing now)
TCP options and ToS (QoS) flag
FIXED peer number limit
FIXED some spikes in ingress/download
FIXED problems when other up and down limit
commands and options for network limiting
works very well e.g. for 50 KiB/sec up and down
ToS (QoS) flag
peer number limit
TODO some spikes in ingress/download
TODO problems when other up and down limit
added "otshell utils" - simple logging (with colors, text files channels)
Usage:
default is lmdb for blockchain branch:
$ make release
same as:
$ DATABASE=lmdb make release
for original in-memory implementation:
$ DATABASE=memory make release
Use copied value of seed node index during thread creation, not
reference.
- fixes segfault
Use boost:🧵:try_join_until() instead of an atomic flag result
variable for each thread.
Add and handle interrupt for thread timeout.
- fixes segfault where a thread exceeds requested timeout and tries to
assign results to a referenced, but now out-of-scope, variable in
the main thread.
It expects the total number of blocks of main chain, not last block id
(off-by-one error).
This again behaves like the same height assertion done in original
implementation in blockchain_storage::handle_alternative_block().
This allows a reorganization to proceed after an alternative block has
been added.
difficulty.
This fixes the continual reorganization between a main and alternate
chain, using the same two latest blocks from each.
The check that cumulative difficulty of the alternate chain is bigger
than main's was not using main's last block, but incorrectly using the
passed-in block's previous block. main_chain_cumulative_difficulty was
being used in two different ways. This has been split up to keep use
of main_chain_cumulative_difficulty consistent.
Remove have_block() check from Blockchain::handle_block_to_main_chain().
Add logging to have_block().
This allows blockchain reorganization to proceed further.
have_block() check here causes an error after a blockchain reorganize
begins with error: "Attempting to add block to main chain, but it's
already either there or in an alternate chain."
While reorganizing to become the main chain, a block in the
alternative chain would be refused due to have_block() rightfully
finding it in the alternative chain. The reorganization would end in
rollback, restoring to previous blockchain.
Original implementation didn't call it here, and it doesn't appear
necessary to be called from here in this implementation either. When
needed, it appears it's called prior to handle_block_to_main_chain().
Complete method BlockchainLMDB::remove_output()
- use output index as the key for:
m_output_indices, m_output_txs, m_output_keys
- call new method BlockchainLMDB::remove_amount_output_index()
Add method to remove amount output index.
- BlockchainLMDB::remove_amount_output_index()
- for m_output_amounts
This also fixes the segfault when blockchain reorganization is
attempted.
Use last block id, not number of blocks (off-by-one error).
Fixes error at start of blockchain reorganization: "Attempt to get
cumulative difficulty from height <XXXXXX> failed -- difficulty not in
db"
Implement BlockchainLMDB::get_output_global_index()
- returns global output index for a given amount and amount output
index.
Add information to debug statement for failed ring signature check
within Blockchain::check_tx_inputs()
Fixes bitmonerod RPC call "/getrandom_outs.bin" to return correct
output keys, used in creating a transaction with mixins.
TODO: get_output_global_index() could be refactored with part of
get_output_tx_and_index() as the latter uses the former's
functionality. Keep track of LMDB read transaction.
Fix Blockchain::get_tx_outputs_gindexs() to return amount output
indices.
Implement BlockchainLMDB::get_tx_amount_output_indices() and call it
from the function instead of BlockchainLMDB::get_tx_output_indices()
Previously, Blockchain::get_tx_outputs_gindexs() was instead returning
global output indices, which are internal to LMDB databases.
Allows bitmonerod RPC /get_o_indexes.bin to return the amount output
indices as expected.
Allows simplewallet refresh to set correct amount output indices for
incoming transfers. simplewallet can now construct and send valid
transactions (currently only without mixins).
This is a fix that doesn't require altering the structure of the
current LMDB databases.
TODO:
This can be done more efficiently by adding another LMDB database
(key-value table).
It's not used during regular transaction validation by bitmonerod. I
think it's currently used only or mainly by simplewallet for just its
own incoming transactions. So the current behavior is not a primary
bottleneck.
Currently, it's using the "output_amounts" database, walking through a
given amount's list of values, comparing each one to a given global
output index. The iteration number of the match is the desired result:
the amount output index. This is done for each global output index of
the transaction.
A tx's amount output indices can be stored in various other ways
allowing for faster lookup. Since a tx is only written once, there are
no special future write requirements for its list of indices.
As it is useful for functions calling BlockchainDB functions to know
whether an exception is expected (attempting to get a block that doesn't
exist and counting it missing if not, to save time checking if it
does, for example), the inline functions throw{0,1} need to keep the
exception type information.
Slight comment update due to copy/paste failure.
1b46226 std::atomic_flag has no copy/move constructor, can't have a vector (Thomas Winget)
df53c0a small typo in previous commit (Thomas Winget)
4a53898 DNS seed timeout and fallback (Thomas Winget)
Fixes problem of obtaining incorrect outputs used for tx input.
Reverts to earlier intended behavior that was fixed in previous
commit's split of get_output_tx_and_index into two functions.
Ideally, the log would go in the exception's ctor, but
two log levels are used, so I'd need to specify the level
in the ctor, which isn't great as it's not really related
to the exception.
hard-coded config folder, hard-coded BlockchainDB subclass.
Needs finessing, but should be testable this way.
