* 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
* wip - coinbase maturity and output lock height docs
* tbd spend an output
* expand on how we prove ownership of an output to spend it
* add proposed solution
* fixup output hash description
* better error messages when `wallet restore` fails
* wallet info: show height, and where we got the height number from
* make "grin wallet listen" show some more lifesigns, so users can know it's running fine
* Make total_difficulty the sum of network difficulty, not whatever the miner happened to mine.
- Only for Testnet2 / Mainnet (hardforks Testnet1)
- update chain::pipe validate_header to validate according to Testnet2 rules for cumulative difference
Fixes#280
* tests that should ignore (network) difficulty
* fn new_block is explained as "utility to create a block without worrying about the key or previous header" so it gets network difficulty := 0 too
* update tx pool tests (going with "minimum" for network difficulty for now)
* add ERR outputs about bannable offences
(#406 should know about these)
* whitespace fix
* mine_simple_chain: Probably DON'T overwrite difficulty (?)
* core/mod tests "reward_empty_block" and "reward_with_tx_block" tests set to use lowest network difficulty possible
* First steps converting transaction workflow to be aggsig-enable
* integrating updated version of aggsig, which gives greater control over the contents of e
* added wallet transaction test to testing framework to enable testing the whole thing, completed interaction as far as inital response from recipient
* more aggsig work, final signature is produced now
* Construction of aggsig transaction now working to the point of the signature being built
* aggsig transactions working end-to-end in the nominal case
* refactor aggsig verify from commit and fix some tests
* more cleanup and test fixing
* cleaning up automated tests
* test+formatting fix
Due to the construction of PMMRs the last element, when its a leaf,
can never be pruned as it has no parent yet and it will be needed
to calculate that hash. To work around this, we now insert coinbase
outputs first to add at least one output of padding.
Also changed the `set_sumtree_root` function on chain a bit to allow
setting the roots on a fork. Mostly useful for tests.
Added new test case to handle both the issue above and spending
transactions within a fork.
On Fedora, Linux headers aren't enough to build `rocksdb`, as suggested in #549. `clang` is also required. Adds note to troubleshooting to help with this.
* Change name of get_peer to get_connected_peer and add a get_peer method with store
* Change to get_connected_peer
* Added handler for GET peers/a.b.c.d
* Add minor document fixes
- fix broken link
- fix shell command formatting
- fix typo
* Add FAQ entry dealing with rocksdb
When compiling Grin without Linux headers the build process exits with
an opaque error message. Adding the header files fixes this.
References #549.
* Adding kcov code coverage to chain and core modules
* Adjust travis.yml to wget kcov from mimblewimble org
* Add codecov badge to README.md
* Fix repo name in badge to grin, from kcov
When applying a fork, everything is done in memory to be able to
rewind if it's either invalid or doesn't have more work. But
checking for the UTXO index was done only against the store. Now
checking the memory as well to find UTXOs that haven't been
stored yet.
The method `is_unspent` hadn't been fixed with the other sumtree
functions to check the MMR before deciding whether something is
really unspent. This is now fixed and also checks the output
hash is the one we expect.
* Add term and grin_p2p for grin client
* Setting msg as public for the client
* Specifying binary for cargo build
* Minimal client implementation
* Using server configuration for the client
* Display current chain height
* Display difficulty and last block pushed
* Remove unneeded secp256k1 dependency
* 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
* wip
* rework check_orphans to be smart about _which_ orphan(s) to check
* cleanup
* limit max of 100 blocks at a time, and corresponding 100 max orphan blocks
* distinguish select (among futures) from select coins. Regex search in project for select\b shows we hardly use select, but maybe could use it to add timeouts more cleanly. ("Want to add a timeout to any future? Just do a select of that future and a timeout future!" from https://aturon.github.io/blog/2016/08/11/futures/)
* remove a trailing space
* FAQ.md - fix typo
* wallet: display problematic tx
* update FAQ build troubleshooting to cover #443
* stdout_log_level = Info
file_log_level = Debug
* sync: show total diff @ height when syncronization is completed
* better wallet send dest format error
* move INFO "Client conn ... lost" and "Connected to peer" down to Debug
* move some level=Info to Debug, add 1000-block outputs
