39a9db9e update checkpoints (Riccardo Spagni)
|
|
After popping blocks from the old chain, the hard fork object's
notion of the current version was not in line with the new height,
causing the first blocks from the new chain to be rejected due
to a false expection of a newer version.

dfbb85b6 blockchain: fix setting non trovial alternate chain as invalid (moneromooo-monero)
|
|
A bug in cold signing caused a spurious pubkey to be included
in transactions, so we need to ensure we use the correct one
when sending outputs from one of those.
|
|
The wrong iterator was being used.
Also preincrement iterators to avoid possibly invalidating them,
I'm not sure this is necessary, but let's be safe.
|
|
This will ensure the early 0.10 daemons will barf at the fork
height, and not a bit later, which could be confusing.

8f6ec90c blockchain: reject invalid pubkeys from v4 (moneromooo-monero)
|
|
|
|
|
|
If the block reward to use for the fee calculation can't be
calculated (should not happen in practice), use a high bound,
so we use a fee overestimate that will be accepted by the network.
|
|
|
|
|
|
|
|
The vast majority of transactions will have just one tx pubkey,
but a bug with cold wallet signing caused two such keys to be
there, with the second one being the real one.
|
|
This will happen when signing a transaction from a cold wallet,
and we don't want the placeholder the hot wallet put in it.

e6deb8a rpc: add a dynamic fee estimation RPC call (moneromooo-monero)
82dbba1 core: dynamic fee algorithm from ArticMine (moneromooo-monero)
|
|
Compute derivation only once per tx, instead of once per output. Approx 33% faster while using 75% as much CPU on my machine. Note old functions in cryptonote_core (lookup_acc_outs and is_out_to_acc) are still used by tests.
|
|
|
|
The fee will vary based on the base reward and the current
block size limit:
fee = (R/R0) * (M0/M) * F0
R: base reward
R0: reference base reward (10 monero)
M: block size limit
M0: minimum block size limit (60000)
F0: 0.002 monero
Starts applying at v4

a6bc110 patched parameter type bug that was causing failure on 32 bit (Dion Ahmetaj)
|
|
25% of the outputs are selected from the last 5 days (if possible),
in order to avoid the common case of sending recently received
outputs again. 25% and 5 days are subject to review later, since
it's just a wallet level change.

This change adds the ability to create a new unsigned transaction
from a watch only wallet, and save it to a file. This file can
then be moved to another computer/VM where a cold wallet may load
it, sign it, and save it. That cold wallet does not need to have
a blockchain nor daemon. The signed transaction file can then be
moved back to the watch only wallet, which can load it and send
it to the daemon.
Two new simplewallet commands to use it:
sign_transfer (on the cold wallet)
submit_transfer (on the watch only wallet)
The transfer command used on a watch only wallet now writes an
unsigned transaction set in a file called 'unsigned_monero_tx'
instead of submitting the tx to the daemon as a normal wallet does.
The signed tx file is called 'signed_monero_tx'.

This reverts commit 78035d2b6c9922f4cd730df0766aa74f4854ccb2.
The patch doesn't work, and causes constant SYNCHRONIZED OK spam.

This is fine if our local chain is so small that it is entirely
contained within the last jump in the peer's short chain history.

06bb692 cmake: support BUILD_SHARED_LIBS built-in option (redfish)
e1c7af3 cmake: transitive deps and remove deprecated LINK_* (redfish)
54010b9 crypto: armv7: slow-hash: remove redundant source include (redfish)
|
|
This saves on an exception dump when trying to write to /
after finding a block.
|
|
Keep the immediate direct deps at the library that depends on them,
declare deps as PUBLIC so that targets that link against that library
get the library's deps as transitive deps.
Break dep cycle between blockchain_db <-> crytonote_core.
No code refactoring, just hide cycle from cmake so that
it doesn't complain (cycles are allowed only between
static libs, not shared libs).
This is in preparation for supproting BUILD_SHARED_LIBS cmake
built-in option for building internal libs as shared.

b8c03a5 Remove blocks_per_sync limits (Howard Chu)
|
|
Since this queries block heights for blocks that may or may not
exist, queries for non existing blocks would throw an exception,
and that would slow down the loop a lot. 7 seconds to go through
a 30 hash list.
Fix this by adding an optional return block height to block_exists
and using this instead. Actual errors will still throw an
exception.
This also cuts down on log exception spam.
|
|
The code used to cap at 5000 blocks per sync. It also treated 0 as 1.
Remove these checks; if specified as 0 do no periodic syncs at all.
Then the user is responsible for syncing in some external process.

91ca0b4 core: allow empty global indices for txes with empty vout (moneromooo-monero)

dc411ea Change default db-sync-mode to fast, not fastest (Howard Chu)
|
|
|
|
It is slightly smaller, but requires all rings to have the real
input on the same index, so can only be used for single input txes.
|
|
|
|
|
|
|
|
When RingCT is enabled, outputs from coinbase transactions
are created as a single output, and stored as RingCT output,
with a fake mask. Their amount is not hidden on the blockchain
itself, but they are then able to be used as fake inputs in
a RingCT ring. Since the output amounts are hidden, their
"dustiness" is not an obstacle anymore to mixing, and this
makes the coinbase transactions a lot smaller, as well as
helping the TXO set to grow more slowly.
Also add a new "Null" type of rct signature, which decreases
the size required when no signatures are to be stored, as
in a coinbase tx.
|
|
This allows the key to be not the same for two outputs sent to
the same address (eg, if you pay yourself, and also get change
back). Also remove the key amounts lists and return parameters
since we don't actually generate random ones, so we don't need
to save them as we can recalculate them when needed if we have
the correct keys.
|
|
Nothing is pruned, but this allows easier changes later.
|
|
The whole rct data apart from the MLSAGs is now included in
the signed message, to avoid malleability issues.
Instead of passing the data that's not serialized as extra
parameters to the verification API, the transaction is modified
to fill all that information. This means the transaction can
not be const anymore, but it cleaner in other ways.
|
|
for future expansion
|
|
This element is used in the generation of the MLSAG, but isn't
needed in verification.
Also misc changes in the cryptonote code to match, by mooo.
|
|
Saves some substantial space.
Also avoid calculating tx hashes we don't need.
|

Scheme design from luigi1114.
|
|
They can be reconstructed from vout
|
|
|
|
|
|
|
|
Allows the fake outs to be in different positions for each ring.
For rct inputs only.
|
|
|
|
|
|
Since these are needed at the same time as the output pubkeys,
this is a whole lot faster, and takes less space. Only outputs
of 0 amount store the commitment. When reading other outputs,
a fake commitment is regenerated on the fly. This avoids having
to rewrite the database to add space for fake commitments for
existing outputs.
This code relies on two things:
- LMDB must support fixed size records per key, rather than
per database (ie, all records on key 0 are the same size, all
records for non 0 keys are same size, but records from key 0
and non 0 keys do have different sizes).
- the commitment must be directly after the rest of the data
in outkey and output_data_t.
|
|
to protect the non-signatures parts of the tx from tampering.
|
|
The mixRing (output keys and commitments) and II fields (key images)
can be reconstructed from vin data.
This saves some modest amount of space in the tx.
|
|
rather than using the current one. No functional changes, but may
save some bugs in the future.
|
|
It is not yet constrained to a fork, so don't use on the real network
or you'll be orphaned or rejected.
|
|
It may be suboptimal, but it's a pain to have to rebuild everything
when some of this changes.
Also, no clue why there seems to be two different code paths for
serializing a tx...
|
|
|
|
to get random ringct outputs to mix with
|
|
|
|
|
|
|
|
|
|
This plugs a privacy leak from the wallet to the daemon,
as the daemon could previously see what input is included
as a transaction input, which the daemon hadn't previously
supplied. Now, the wallet requests a particular set of
outputs, including the real one.
This can result in transactions that can't be accepted if
the wallet happens to select too many outputs with non standard
unlock times. The daemon could know this and select another
output, but the wallet is blind to it. It's currently very
unlikely since I don't think anything uses non default
unlock times. The wallet requests more outputs than necessary
so it can use spares if any of the returns outputs are still
locked. If there are not enough spares to reach the desired
mixin, the transaction will fail.
|
|
This constrains the number of instances of any amount
to the unlocked ones (as defined by the default unlock time
setting: outputs with non default unlock time are not
considered, so may be counted as unlocked even if they are
not actually unlocked).
|
|
This code should die anyway.
|
|
It's not really needed, it used to be an optimization for when
that code was not using the db and needed to recalculate things
fast on startup.

It sets the max number of threads to use for a parallel job.
This is different that the number of total threads, since monero
binaries typically start a lot of them.

eventually go over MONEY_SUPPLY, overflowing 64 bits. There was
a check added to blockchain_storage, but this was not ported to
the blockchain DB version.

This can generate non decomposed outputs for very large block
rewards (or not so large ones if a miner decides to not quantize
the block rewards). Out of an abundance of caution, we refuse
to generate those. They are still accepted by the consensus code,
however.

This allows appropriate action to be taken, like displaying
the reason to the user.
Do just that in simplewallet, which should help a lot in
determining why users fail to send.
Also make it so a tx which is accepted but not relayed is
seen as a success rather than a failure.
|
|
This is a list of existing output amounts along with the number
of outputs of that amount in the blockchain.
The daemon command takes:
- no parameters: all outputs with at least 3 instances
- one parameter: all outputs with at least that many instances
- two parameters: all outputs within that many instances
The default starts at 3 to avoid massive spamming of all dust
outputs in the blockchain, and is the current minimum mixin
requirement.
An optional vector of amounts may be passed, to request
histogram only for those outputs.
|
|
This was meant to go in v2, but the miner tx slipped through
the cracks as it doesn't go through the main tx verification
since it doesn't get added to the pool.

The functions in src/cryptonote_core/checkpoints_create.{h,cpp} should
be member functions of the checkpoints class, if nothing else for the
sake of keeping their documentation together.
This commit covers moving those functions to be member functions of the
checkpoints class as well as documenting those functions.
|

All functions in src/cryptonote_core/checkpoints.h are now documented in
doxygen style.
checkpoints.cpp has been reviewed, one function has been marked for
discussion on correctness.
|
|
|
|
All functions are now documented in doxygen format. Comments have been
updated to reflect the current state of the code. Many areas for
improvement in clarity and design have been noted, as well as cruft to
be removed. These changes are not reflected in this commit both to
allow time for comment and to keep commits organized by purpose.

This is already the default for the daemon, but by checking a command

Initialize the variable to false so it's not dependent on an external

c2a1fee simplewallet: prompt for private keys when generating wallets (moneromooo-monero)

|

|

It is similar in use to --restore-from-view-key, but also expects
a spend private key.
Requested by luigi1112, and useful to restore MyMonero wallets.
|
|
|
|
|
|
To avoid special cases
|
|
It can now be set by some other code, and is thus tested
|
|
We also replace the --fakechain option with an optional structure
containing details about configuration for the core/blockchain,
for test purposes. This seems more future friendly.
|
|
Not doing so will prevent the new genesis block from being
reset if a switch past v1 had occured already.
|
|
|
|
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.

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
|
|
- 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.
