* use a short timeout when opening the connection to possible peers
lots of peers in the db are unavailable and we do not want to wait 60s for these
* also randomize peers so we don't always try and connect to peers with low ip addresses
* bump timeout up to 5s for peering
Renamed mining parameter mode to chain type, with existing types
of CI testing, user testing, testnet1 or mainnet. The public
chains (testnet1 and mainnet) come with their fully pre-defined
genesis block.
Still need to set the nonce and cycle for testnet1 genesis.
* bad case of trying to rewind to block header height 0
* rewind_to_genesis appears to work
* do not assume genesis block at height 0 is empty, pass full block in to rewind, check for last output and kernel, use index 0 if block is empty
* use HashMap internally for tracking connected peers (to avoid duplicates)
* reuse the handshake on the server so we can track our own nonce to avoid self connections correctly
* make sure we start up the clean_peers loop even in seedless mode
* logging in monitoring peers loop
* simplify monitoring for no seeds
* fixup and cleanup simulnet tests (real seeds in places)
* only start the sync if we have either seeds or peers that we know about, exit syncer safely if we have no connected peers
* default wallet receive to listen on 127.0.0.1, optional flag on wallet command to listen on 0.0.0.0
* fix simulnet for new wallet port/interface config
Moved the HTTP APIs away from the REST endpoint abstraction and
to simpler Hyper handlers. Re-established all routes as v1.
Changed wallet receiver port to 13415 to avoid a gap in port
numbers.
Finally, rustfmt seems to have ignored specific files arguments,
running on everything.
* mount v2 router for flexibility, wallet checker now refreshes multiple outputs via single api call
* fix the api router
* wallet api handlers, miner uses wallet_client
* retry logic via tokio_retry, miner creates new coinbase output via wallet API (retries several times)
* move wallet client into wallet crateand rework the lock acquisition logic to use tokio_retry
* Fix for the chain pipeline partly relying on an outdated head,
leading to not properly recognizing a fork and inconsistent sum
tree state.
* Do not drop block requests during sync that don't get satisfied,
retry enough time to get them and avoid stall.
* Always validate header, even in sync where we may have validated
it already. We don't want a block coming from a peer that could
squeeze through with an invalid header.
* When syncing, do not mark blocks that were errored by the chain
as received (typical case: orphan). Keep retrying.
* Improved chain state dump for debugging.
* Do not add to orphans blocks too far in the future.
* Better error reporting on db errors.
* Related sync test fixes.
TODO figure out why syncing peers timeout so often, very useful
to test but not that great for a fast sync experience.
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.
* 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.
* introduce grin_keychain, encapsulate derivation of secret_keys
* core compiles against keychain, tests don't run yet
* core tests are now passing against keychain
* wip - getting wallet working with keychain
* add util and keychain to travis test matrix
* basic test around key derivation
* Integrate PMMR and its persistent backend with the Chain
* Chain can set tree roots; PMMR backend discard
* Check spent and prune for each input in new block
* Handling of forks by rewinding the state
* More PMMR tests and fixes, mostly around rewind
* Rewrite get_unspent to use the sumtrees, fix remaining compilation issues
* Adding ability to load multiple mining plugins in parallel via cuckoo miner
* updating with newest cuckoo-miner changes
* revert default config value
* update pow document with link to podcast
