* wip BlockMarker struct, get rid of PMMRMetadata
* use rewind to init the txhashet correctly on startup, we do not need to track pos via metadata (we have block markers), we do not need to open the txhashset with specific pos (we have rewind)
* better logging on init
* keep rewinding and validating on init, to find a good block
* use validate_roots on chain init
* rewind to header as part of txhashset validation
otherwise we risk including a new block and the roots do not match
* fix bug in rm_log rewind (wants to be inclusive of provided index)
* put block marker in the index so we can rewind correctly
during validation of the new txhashset
* rustfmt
* 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
* wip
* failing test for being too eager when pruning a sibling
* commit
* rustfmt
* [WIP] modified get_shift and get_leaf_shift to account for leaving "pruned but not compacted" leaves in place
Note: this currently breaks check_compact as nothing else is aware of the modified behavior
* rustfmt
* commit
* rustfmt
* basic prune/compact/shift working
* rustfmt
* commit
* rustfmt
* next_pruned_idx working (I think)
* commit
* horizon test uncovered some subtle issues - wip
* rustfmt
* cleanup
* rustfmt
* commit
* cleanup
* cleanup
* commit
* rustfmt
* contains -> binary_search
* rustfmt
* no need for height==0 special case
* wip - works for single compact, 2nd one breaks the mmr hashes
* commit
* rustfmt
* fixed it (needs a lot of cleanup)
we were not traversing all the way up to the peak if we pruned an entire tree
so rm_log and prune list were inconsistent
* multiple compact steps are working
data file not being copmacted currently (still to investigate)
* cleanup store tests
* cleanup
* cleanup up debug
* rustfmt
* take kernel offsets into account when summing kernels and outputs for full txhashset validation
validate chain state pre and post compaction
* rustfmt
* fix wallet refresh (we need block height to be refreshed on non-coinbase outputs)
otherwise we cannot spend them...
* rustfmt
* 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
* adding file position index data accessable to the chain, and allowing for storage of such within db
* missing file
* restart files at last recorded position in stored file metadata
* just use tip to store last pmmr index information
* error handling
* test fix
* family_branch() to recursively call family() up the branch
todo
- we hit a peak, then we need to get to the root somehow
- actually get the hashes to build the proof
* wip
* some additional testing around merkle tree branches
* track left/right branch for each sibling as we build the merkle path up
* MerkleProof and basic (incomplete) verify fn
* I think a MerkleProof verifies correctly now
need to test on test case with multiple peaks
* basic pmmr merkle proof working
* MerkleProof now serializable/deserializable
* coinbase maturity via merkle proof basically working
* ser/deser merkle proof into hex in api and wallet.dat
* cleanup
* wip - temporarily saving merkle proofs to the commit index
* assert merkle proof in store matches the rewound version
there are cases where it does not...
* commit
* commit
* can successfully rewind the output PMMR and generate a Merkle proof
need to fix the tests up now
and cleanup the code
and add docs for functions etc.
* core tests passing
* fixup chain tests using merkle proofs
* pool tests working with merkle proofs
* api tests working with merkle proof
* fix the broken comapct block hashing behavior
made nonce for short_ids explicit to help with this
* cleanup and comment as necessary
* cleanup variety of TODOs
* 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
