* A new sync status enum encapsulated in a state struct allows tracking of where sync is at. Leveraging it in the TUI to provide more helpful messages.
* Percentage progression for most sync steps
* Added sizeshift to proof of work and encoding as VLQ
* Fix some loose ends to get things to compile
* Rename sizehift to min_sizeshift
* Pipeline checks for PoW Cuckoo Cycle size shift and adjustment
factor before difficulty comparison.
* Working delta+VLQ encoding of u64 PoW, unfortunately still a
little larger than u32, at least for Cuckoo30.
* Changed binary encoding of proof of work to a sequence of exact
compact bit representation of each nonce. Somewhat simpler,
shorter and matches the data to be hashed.
* Few fixes based on @tromp feedback:
* Max nonce is 2^(N-1)
* Need a separate constant for reference sizeshift
* Cuckoo implementation now conserves sizeshift. Test providing a
block at higher sizeshift.
* Last small overflow protection
We used to hash the hash of the header, needlessly. This also
makes a few function signatures more explicit.
Note that this is consensus breaking and should be accompanied
with a similar change on the cuckoo-pow repository:
6fcecf516aFixes#1066
* Migrate main node store to LMDB
In preparation to using LMDB as a wallet database, migrate the
node db. There's no point in having 2 key-value stores.
In addition LMDB provides a few advantages as a node db, namely a
much faster build (compared to RocksDb), lesser dependencies and
transactions.
* Migrated p2p store to lmdb, stuff compiles
* More fixes, chain tests starting to pass
* Fixed txhashset rollback messing with block save and general batch delimitation. Chain tests passing.
* rustfmt
* LMDB max map size of 10MB isn't really workable. Half TB seems reasonable.
* Fix wallet tests
* Rather crucial commit was missing
* rustfmt
* Fixing new merged tests following lmdb changes
* rustfmt
* * Make txhashset validation read-only on fast sync to avoid having
a really long open transaction.
* Fix deadlock in new block processing, batch should always be
created within a txhashset lock (when they interact).
* Comment about batch and txhashset interlacing
* Fix store tests to use batch
* Externalize wallet config and seed
* Converted direct read access to file outputs map to an iterator
* Cleaned up and simplified wallet Backend trait:
* No more direct mutable access to internal structures (HashMap)
* Batch interface for all writes
* Remove unneeded read wrapper (read_wallet)
* rustfmt
* First (incomplete) pass at wallet LMDB backend
* Progressing on lmdb backent iml
* Added batch impl for LMDB wallet backend. Pretty much done with it, but not sure how to deal with commit (owned).
* rustfmt
* Wrapping LMDB batch around a refcell to work around borrow rules
* Compilation up to grin chain
* Add kernel commitments sum and kernel and output MMR sizes to block header
* Sum a block without including previous sums, cleanup. Blocks are now summed and validated based on their own totals and not the totals since genesis. This allows to get rid of BlockSum and simplified the setting of a new block's roots, kernel sum and MMR sizes. Fixes#116
* Additional kernel MMR validation to check all prior header roots successively
* Wallet tests fix
* StratumServer RPC extra-quotes fix
* better - skip intermediate string
* Fix invalid json _ok_ response
* Undo protocol-breaking change to ok response
* use RpcError structure rather than string to avoid extra quoting
* First pass at restructuring the keychain crate and introducing a Keychain trait
* Parameterized everything that had to. Stuff compiles.
* More stuff compiles, fix most tests
* Big merge, pushing down opening the keychain forced adding factory methods on trait
* Test fixes for pool and servers crate
* move http calls out from libwallet internal
* rustfmt
* start to think about wallet communication traits
* rustfmt
* start of factoring out wallet client trait
* rustfmt
* move node_url trait fn into walletclient
* rustfmt
* comms factored out (with exception of wallet restore)
* rustfmt
* fix test
* rustfmt
* further test fix
Small refactoring of one folder, if it makes sense I could extend the scope.
* Remove some cloning (real and just verbosity in the code)
* Naming conventions like to/into*
* Some Clippy's suggestions
I found that we don't use field init shorthand syntax, so I didn't touch this part, was it discussed before?
* verify a tx like we verify a block (experimental)
* first minimal_pool test up and running but not testing what we need to
* rework tx_pool validation to use txhashset extension
* minimal tx pool wired up but rough
* works locally (rough statew though)
delete "legacy" pool and graph code
* rework the new pool into TransactionPool and Pool impls
* rework pool to store pool entries
with associated timer and source etc.
* all_transactions
* extra_txs so we can validate stempool against existing txpool
* rework reconcile_block
* txhashset apply_raw_tx can now rewind to a checkpoint (prev raw tx)
* wip - txhashset tx tests
* more flexible rewind on MMRs
* add tests to cover apply_raw_txs on txhashset extension
* add_to_stempool and add_to_txpool
* deaggregate multi kernel tx when adding to txpoool
* handle freshness in stempool
handle propagation of stempool txs via dandelion monitor
* patience timer and fluff if we cannot propagate
to next relay
* aggregate and fluff stempool is we have no relay
* refactor coinbase maturity
* rewrote basic tx pool tests to use a real txhashset via chain adapter
* rework dandelion monitor to reflect recent discussion
works locally but needs a cleanup
* refactor dandelion_monitor - split out phases
* more pool test coverage
* remove old test code from pool (still wip)
* block_building and block_reconciliation tests
* tracked down chain test failure...
* fix test_coinbase_maturity
* dandelion_monitor now runs...
* refactor dandelion config, shared across p2p and pool components
* fix pool tests with new config
* fix p2p tests
* rework tx pool to deal with duplicate commitments (testnet2 limitation)
* cleanup and address some PR feedback
* add big comment about pre_tx...
Reuse unused coinbase key in stratum server. Instead of asking a new key id from the wallet every time, the stratum server now provides the older one again if it hasn't been used (the local node didn't end up mining a block).
Previous code used to always get full blocks from archival peers.
Fast sync nodes shouldn't need to, other fast sync nodes have all
the history they need. This only uses archival nodes when blocks
are requested at a height that's older than the horizon.
We test if we're in fast sync or not by checking if our head is
more recent than horizon. However, by the time we get the data and
validate, more blocks have passed, and we'd be after horizon again.
So we request the txhashset for a more recent block than the one
at horizon.
The current value was 20, leaving only 20 min of slack, which isn't
enough for debug builds and isn't future-proof. Change to use
`0.9*horizon`, leaving about 2.5 hours.

a general txhashset lock was introduced.
