* simplify tx validation and aggregation
we *only* need to account for reward when building a block from txs
* rustfmt
* cleanup and tests passing
* rustfmt
* better comments in with_reward()
* fix wallet tests
* Sort pool tx by fee over weight for mining. Fixes#1105
* Bucketing dependent transactions before weighing. Minor tx weight fixes.
* Limit length of tx chain, cleanup and test fixes
* Cleanup all mining references to a hardcoded tx count
* Small test improvement, cleanup
* Include commitments non-duplicate checks in aggregate
* Remove said check from the pool
* Block building now uses tx aggregation to reduce duplication
* Transaction max weight expressed in terms of block weight
* Cleaned up max block sizes, so everything is in therms of weight
* Cleanup block max constants
* Rename verify_size -> verify_weight
* add new core mmr routine upon which others should be built more efficiently
* tons of pmmr optimizations and simplifications
* fix typo and extend docs
* change initial spaces to tab to fix indentation
Fuzz test found the folowing issues with reading block header:
* Unbounded cuckou_sizeshift field in Proof
* Different timestamp range after migration to chrono crate
* Check txhashset content before zip/unzip
* Add header in txhashset verification
* Add copy function and test
* Add file util
* Now check and remove unexpected files instead of just crashing
* improve: time crate flagged as deprecated, switch to actively maintained chrono crate
* improve: complete the switching from deprecated time crate to chrono crate, for all the tests part
* improve: complete switching to chrono crate, for the left tests in 'chain' and 'wallet'
* Make grin.toml config optional. Mirror exisiting config parameters in grin.toml to source code, so binary can run without a config file. Add test for it.
* fixup! Make grin.toml config optional
* fix misbehaving simulnet fastsync test
cleanup redundant cutoff vs bitmap params is rewind and check_compact
* make sure we do not verify full kernel history on a writeable txhashset extension
rework simulnet simulate_fast_sync test to be more robust
* fixup store tests
* sleep for a bit longer to give nodes time to update
their sync_state correctly
* tweak timing of simulate_block_propagation
* Handle SIGINT and SIGTERM (#1180)
* Handle SIGINT and SIGTERM
* pin croaring to version 0.3.2 until we get the clang conflict sorted out (#1183)
* document proposals for - (#1190)
* conditional timelocked outputs, and
* conditional relative timelocked outputs
* problem with validation on rewind
* update difficulty scenarios to display much more data
* correct average sum output
* update pre-genesis block padding to just use previous block's data
* 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 do not need Merkle proofs to spend coinbase outputs
we only need the output_mmr_size from the block header
* tests working with no Merkle proofs in inputs
* implement prune_list as a bitmap
and simplify
* cleanup prune_list, use maximum()
* handle migration of prune_list to new bitmap prun file
* legacy filename consts
* cleanup and docs
* 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
