* introduce protocol version to deserialize and read
* thread protocol version through our reader
* example protocol version access in kernel read
* fix our StreamingReader impl (WouldBlock woes)
* debug log progress of txhashset download
* introduce HeaderVersion (was u16) for type safety
cleanup pow ser/deser (version unused)
* fixup tests for HeaderVersion
* validate header version during header deserialization
* Introduce optional size_file.
Support fixed size data file via an optional elmt_size.
Support variable size data file via optional size_file.
* remember to release the size_file
* fix scoping for windows support
* introduce DataFile<T> to hide the LEN handling
use slices rather than vec<u8> where possible
* cleanup
* use DataFile<Hash> and not HashFile
* fix core tests
* refactor header MMR to use regular backend
this lets us store header hashes in the mmr data file
the hashes in the hash file are "hash with index"
* rustfmt
* get_header_hash(pos) on header extension
* rustfmt
* cleanup
* cleanup
* comments
* cleanup
* fixup testelem so tests work
* headers msg is now "streamed" off the tcp stream
* rustfmt
* cleanup
* move StreamingReader into ser.rs
extract read_exact out into util crate
* rustfmt
* use FixedLength to define serialized size in bytes of various structs
replace usages of mem::size_of() with ::LEN so we correctly calculate serialized sizes in bytes
* rustfmt
* cleanup pmmrable and len()
introduce FixedLength trait with a const LEN
make Hash impl FixedLength for consistency
* rustfmt
* store tests cleanup
* rustfmt
* whats going on with those comments and rustfmt?
* Move Proof and Difficulty types to pow module. Difficulty scaling calculation.
* Diffculty scaling and size shift for 2nd PoW
* Backport e7eb26ee
* Test compilation fixes
* Scaling only need to go one way, as @tromp pointed out
* 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
Fuzz test demonstrated that the current implemenation panics on reading from the network when serialized tx. Contains for example huge number of input or outputs. It allows a mailicious sender
to kill the server.
* hash_with_index on non-leaf nodes
rework the Merkle proof to include the pos of each sibling in the path
* rustfmt
* cleanup
* cleanup
* use get_from_file in validate (children may have been "removed")
* rustfmt
* fixup store tests
* Implementation of compaction for the chain. Single entry point on the chain triggers compaction of all MMRs as well as the cleanup of the positional index and full blocks.
* API endpoint, additional tests and more fixes for compaction
* Also prune PMMR metadata, minor bug fix
* PMMR store tests fix
* beginning to add bullet proof messages
* Updated core transaction creation to embed the output's value and switch commit hash as part of the rangeproof message
* formatting issue
* more formatting issues
* Removing conditional feature compliation.. just bulletproofs from now on
* ensure MAX_PROOF_SIZE uses bulletproof sizing instead of earlier version
* updated with switch commit committed to in extra data
* accidentally commented out bullet-proof-size feature
* beginning to remove sum
* continuing to remove sumtree sums
* finished removing sums from pmmr core
* renamed sumtree files, and completed changes+test updates in core and store
* updating grin/chain to include removelogs
* integration of flatfile structure, changes to chain/sumtree to start using them
* tests on chain, core and store passing
* cleaning up api and tests
* formatting
* flatfiles stored as part of PMMR backend instead
* all compiling and tests running
* documentation
* added remove + pruning to flatfiles
* remove unneeded enum
* adding sumtree root struct
* wip - basic tx pool lookup for kernel short ids (compact block hydration)
* use the nonce in the compact_block to correctly generate short_ids for lookup
* query the tx pool based on kernel short_ids
* tests passing
* cleanup some logging
* cleanup logging
* WIP - split the key in final tx step
store "offset" on transaction itself
* rebase
* commit
* tx with offset
* got a test tx validating successfully using a sig from a split key and the appropriate offset
* sum up the offset for the block_header
* fix size tests for blocks and compact blocks (header now includes offset)
* use txs with offsets in most of the core tests
some tests now failing
* build kernel from k1G (k2 stored on tx, sum stored on header)
* commit
* tx now has vec of kernels
rework tx and kernel validation
* add test for tx cut_through
* wip - working on splitting in aggsig
* split the key when creating the initial sender aggsig context
* cleanup
* cleanup
* code needs claning up but split keys working for sender/receiver aggsig flow
* cleanup debug logging
* fix tests
* fix merge and basic cleanup
* fix keychain tests to use new tx_id
* [wip] short_id implementation (first attempt)
todo - make this more reusable (a trait?) so we can use it for inputs/outputs/kernels easily
* factor short_id support out into ShortIdentifiable trait
* block can now be converted to compact_block
rename existing block.compact() -> block.cut_through()
* expose compact block representation via block api endpoint
optional with ?compact query param
* experiment with lock_heights on outputs
* playing around with lock_height as part of the switch commitment hash
* cleanup
* include features in the switch commit hash key
* commit
* rebase off master
* commit
* cleanup
* missing docs
* rework coinbase maturity test to build valid tx
* pool and chain tests passing (inputs have switch commitments)
* commit
* cleanup
* check inputs spending coinbase outputs have valid lock_heights
* wip - got it building (tests still failing)
* use zero key for non coinbase switch commit hash
* fees and height wrong order...
* send output lock_height over to wallet via api
* no more header by height index
workaround this for wallet refresh and wallet restore
* refresh heights for unspent wallet outputs where missing
* TODO - might be slow?
* simplify - do not pass around lock_height for non coinbase outputs
* commit
* fix tests after merge
* build input vs coinbase_input
switch commit hash key encodes lock_height
cleanup output by commit index (currently broken...)
* is_unspent and get_unspent cleanup - we have no outputs, only switch_commit_hashes
* separate concept of utxo vs output in the api
utxos come from the sumtrees (and only the sumtrees, limited info)
outputs come from blocks (and we need to look them up via block height)
* cleanup
* better api support for block outputs with range proofs
* basic wallet operations appear to work
restore is not working fully
refresh refreshes heights correctly (at least appears to)
* wallet refresh and wallet restore appear to be working now
* fix core tests
* fix some mine_simple_chain tests
* fixup chain tests
* rework so pool tests pass
* wallet restore now safely habndles duplicate commitments (reused wallet keys)
for coinbase outputs where lock_height is _very_ important
* wip
* validate_coinbase_maturity
got things building
tests are failing
* lite vs full versions of is_unspent
* builds and working locally
zero-conf - what to do here?
* handle zero-conf edge case (use latest block)
* introduce OutputIdentifier, avoid leaking SumCommit everywhere
* fix the bad merge
* pool verifies coinbase maturity via is_matured
this uses sumtree in a consistent way
* cleanup
* add docs, cleanup build warnings
* fix core tests
* fix chain tests
* fix pool tests
* cleanup debug logging that we no longer need
* make out_block optional on an input (only care about it for spending coinbase outputs)
* cleanup
* bump the build
* added debug logging to see what we're doing in save_pos_index
* add counts to logging
* make sure inputs/outputs in tx are sorted
tweak debug logging
* DRY up sorting of inputs/outputs/kernels via a simple sort() in ser/deser
* add explicit validation fo sort order during tx and block validation
* sort order consensus rule for inputs/outputs/kernels in blocks
* we want a max of 10*num_peers blocks during sync...
not min
* fix test imports
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.
* 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
* 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
