* failing test case that exercises
prepare_mineable_transactions and reconcile_block
and highlights what appears to be unexpected behavior
* adjust the failing test - the failure state is where we have
a tx in the pool *but* it is not in the list of roots in the pool
* zero confirmation txs are now working
introduce update_roots to graph to ensure pool is consistent
after calling remove_pool_transaction
* move update_roots to sweep_transactions so we only call it once
rework update_roots to be more efficient
* use HashSet in reconcile_block to avoid marking txs multiple times
* use HashSet and not HashMap
return from mark_transaction early if already seen tx
Addresses a corner case of sync. If we're still in sync mode but
just caught up to the head, a block could be added through normal
gossip. So we can't short-circuit some of the header handling
even though during sync the header should have already been
validated and saved, because we can still get a block from gossip.
* Adding switch commit to grin outputs
* logging output fix
* adding switch commitment hash to sum tree node
* added hash_with to Hashed trait, to allow for hashing to include another writeable element
* adding hash_with as method in hashed trait
* refactor burn key into key_overrides on keychain
* introduce UnconfirmedChange output status, we can potentially spend these with zero confirmations
* pass in burn_key_id for the burn enabled keychain, spend *all* coins when spending from a wallet, spend UnconfirmedChange coins also
* add comment about simplifying wallet_data.select logic
* replace UnconfirmedChange output status with a more flexible zero_ok, flag on the output data
* fail deserialization if input or outputs are not sorted for txs, fail deserialization if inputs or outputs or kernels are not sorted for blocks, make sure we sort them before serialization
* extract consensus rule into verify_sort_order on VerifySortOrder trait
* rework the sort and write into WriteableSorted trait
* fix wallet sending bug (fees related) so we can test
* refactored read_and_verify_ordered out into ser, used in transaction and block
* rename pubkey -> key_id, these are key identifiers, not public keys
* reduce identifier seize to 10 bytes, get rid of fingerprints (identifiers are now small enough to use as-is)
* IDENTIFIER_SIZE const
* add FeeDispute error for when sender and recipient disagre on fee calculation (should never happen)
* does not need to be mut
* cleaned up some warnings
* added global slog instance, changed all logging macro formats to include logger instance
* adding configuration to logging, allowing for multiple log outputs
* updates to test, changes to build docs
* rustfmt
* moving logging functions into util crate
* add lock_height to Transaction and TxKernel, sign msg including both fee and lock_height in kernel
* make the order of the fields in tx and kernel more consistent
* rename to kernel_sig_msg
* add test to cover adding timelocked tx to pool, where tx is invalid based on current height of the blockchain
* add tests for adding timelocked txs to blocks (valid and otherwise)
Configuration for a minum accept fee base for the transaction
pool. The base is multipled by a weight computed from the
transaction number of inputs, outputs and kernels. The transaction
fee is required to always be larger than the weight times the
base.
min_fee = base * (-1*input_len + 4*output_len + kernel_len)
The weight is set to never be less than one.
Also added a configurable (and fairly naive for now) max pool
capacity in number of transactions.
* store wallet output data in hashmap
* cleanup up commented out code
* pass pubkey/identifier and not derivation around to miner etc.
* fix failing tests
Update coinbase building and block summation to account for half of
the fees going to the coinbase. Forcing fees to be even as a
consequence. Now that we can't build the coinbase independently
from the block (because fees), had to update the miner to keep the
key derivation so a new derivation isn't made any time a new block
gets worked on.
Minor doc and warning cleanups.
