For consistency.
|
|
|
|
Replace temporary assignment that used hardcoded values.
|
|
Ensures the database is consistent.
Also simplifes blockchain_import in that verify mode off has less to
work around.
|
|
This will later allow the HardFork object's DB update functions to be
called when the DB transaction that persists across block add/remove is
open.
|
|
Move block-scope txn start and stop from BlockchainLMDB to BlockchainDB.
|
|
|
|
Note that this doesn't yet cause them to be called during block add.
|
|
|
|
|
|
The HardFork object is needed for the importer to update the hard fork
data when verify mode is off.

|
If it is, it points to reuse of a tx key, which isn't meant to happen.
If it does, a key image collision means that only one of those
outputs is spendable, so the wallet selects the larger amount,
unless that output was spent already.
This causes a discrepancy betewen reported received inputs and
payment total.
Since tx keys are 256 bits, this should never happen except if
done on purpose, or if a sender uses a bad PRNG.
|
|
Locking just one db turns out to not have been a good idea, since
the pool and p2p state fdles have to be used anyway.
Also ensure the directory exists before tring to lock.
|
|
This differs from the original CN code, and there seems to be
no reason to include the block itself, if it was found
|
|
Despite being C++, the stats object is allocated by the underlying
C layer using malloc(3).
|
|
- Blockchain should store if it's running on testnet or not
- moved loading compiled-in block hashes to its own function for clarity
- on handle_get_objects, should now correctly return false if a block's
transactions are missing
- replace instances of BOOST_FOREACH with C++11 for loops in Blockchain.

A boost lock is used to determine whether more than one process
wants to access the database. The boost file_lock doesn't seem
to like locking directories, so we use an arbitrary file in it.
This allows to still run two daemons if they have different
database directories (ie, LMDB/BDB, different data directories).

In particular, ensure we check the status of RPC response structures,
as some functions will return success, but with a BUSY status, when
the daemon is not yet synced, and the response will not filled.

It counts the number of blocks added since last zeroing
|
|
It can flush a particular tx, or the whole pool (the RPC command
can flush a list of transactions too)
|
|
|
|

When a transaction is not found in the pool anymore, it is marked
as failed, and displayed as such in show_transfers.

94b98fb tx_pool: do not accept txes not in a block if they timed out before (moneromooo-monero)
eadbdf3 tx_pool: fix use of invalidated iterator (moneromooo-monero)
3b1d7e0 Fix V1/V2 use of hard fork related parameters (moneromooo-monero)
|
|
This is intended to avoid cases where a timed out tx will be
re-relayed by another peer for which it has not timed out yet,
which would cause the tx to stay in the network's pool for a
long time (until all peers time it out before another one
tries to relay it again).

|
|
|
Some of it uses hardcoded height, which will need some thinking
for next (voted upon) fork.

This improves blockchain reorganization time by allowing one of the more
expensive DB lookups when popping a block to not have to seek through a
long dup list in the "output_amounts" db. This is most noticeable for
HDDs.

The value will be different depending on whether we've reached
the first hard fork, which allows a larger size, or not.
This fixes transactions being rejected by the daemon on mainnet
where the first hard fork is not yet active.

Also add some flags to open, as epee's save_string_to_file does,

|
|
|
|
|
|
This ensures this will be done without fail, as the error prone
matching of every return with a call to KILL_IOSERVICE leads to
hard to debug corruption when one is missing.
|
|
- only try to stop if actually started
- print number of threads before zeroing it
This fixes the suspiciously doubled "Mining has been stopped"
message on exit.
|
|
Blockchain hashes and key images are flushed, and blocks are
pulled anew from the daemon.
The console command is shortened to match bc_height.
This should make it a lot easier on users who are currently
told to remove this particular cache file but keep the keys
one, etc, etc.
|
|
This can happen when the daemon exits, which would also cause
the wallet to crash via unhandled exception
|
|
They do not take the object lock, and are meant to be used only
internally, called from a function which does take the lock.

If the block reward was too high, the verification failed flag
was set, but the function continued. The code which was supposed
to trap this flag and return failure failed to trap it, and,
while the block was not added to the chain, the function would
return success.
The reason for avoiding returning when the block reward problem
was detected was to be able to return any transactions to the
pool if needed. This is now mooted by moving the transaction
return code to a separate function, which is now called at all
appropriate points, making the logic much simpler, and hopefully
correct now.
We also move the hard fork version check after the prev_id check,
as block which does not go on the top of the chain might not
have the expected version there, without being invalid just for
this reason.
Last, we trap the case where a block fails to be added due to
using already spent key images, to set the verification failed
flag.
|
|
|
|
This fixes some double spending tests.
This may or may not be unneeded in normal (non test) circumstances,
to be determined later. Keeping these for now may be slower, but safer.
|
|
Probably paranoid and unnecessary
|
|
Block reward may now be less than the full amount allowed.
This was breaking the bitflipping test.
We now keep track of whether a block which was accepted by the core
has a lower than allowed block reward, and allow this in the test.
|
|
It was missing in the port to DB.
This is actually a noop, so should not have functional changes.
|
|
When rolling over more than one block, the db height will decrease,
but the split height should be constant, as per the original code.
|
|
It was present in the original code
|
|
This can happen when trying to find an amount that does not exist,
and fixes a core test.
|
|
The check was explicit in the original version, so it seems
safer to make it explicit here, especially as it is now done
implicitely in a different place, away from the original check.

Data should be removed in the reverse order it was added. Not doing so

This matches the order of tx removal in
blockchain_storage::purge_block_data_from_blockchain.
|
|
This improves blockchain reorganization time by allowing one of the more
expensive DB lookups when popping a block to not have to seek through a
long dup list in the "output_amounts" subdb. This is most noticeable for
HDDs.
As before, the dup list is still walked if necessary (but in reverse),
and the global output index still confirmed to be the one looked for.
But under proper use, the result will be found at the end of the dup
list, so we start there.
Removing an amount output index is always done in the context of popping
a block, so the global output index being looked for should be the last
one in that amount key's dup list. Even if the txs themselves aren't
removed in reverse order (supposed to be according to original
implementation), the specified amount output index will still be near
the end, because the txs are in the same block.
TEST:
Pop blocks with blockchain_import.
Blocks should be successfully removed with no errors shown.
bitmonerod should be able to start syncing from the reduced blockchain
height.

In particular, <boost/program_options.hpp> blows up daemon.cpp.obj,

This has no effect on the final linked binary size.
|

was always 0, not the wallet's version as I had expected.

This prevents the intermediate thread from exiting properly, as
fork creates a child process with only one thread, so any existing
data_logger thread will not be in the child. Since this thread
sets a flag the data_logger dtor blocks on, all children threads
will hang on exit.
|
|
When throwing an exception from being unable to begin an LMDB
transaction, include the reason.
It's often been due to a write transaction attempted within a write
transaction (batch mode), but there can be other reasons such as write
transaction attempted while database was opened read only, or
environment's map needs to be resized.
|
|
The core tests use the blockchain, and reset it to be able
to add test data to it. This does not play nice with the
databases, since those will save that data without an explicit
save call.
We add a fakechain flag that the tests will set, which tells
the core and blockchain code to use a separate database, as
well as skip a few things like checkpoints and fixup, which
only make sense for real data.
