* call request_block after successful processing header
* cleanup and skip asking for block if header is an orphan
* comments around error handling in receive_header
* rustfmt install instruction gotcha
rustfmt stopped working for me. It turns out people started having trouble with this last year already https://github.com/rust-lang-nursery/rustfmt/issues/2304
* rustfmt on a single file now works! Secrets inside
After `rustup component add rustfmt-preview` I get rustfmt as a command in my terminal.
`rustfmt --help` reveals --write-mode [replace|overwrite|display|plain|diff|coverage|checkstyle] and we've been using the default which is either `overwrite` or `replace` (depending on rustfmt version) and this was changing a bunch of files and a messed up workflow.
* Newcomer-friendly explanation how to use `rustfmt`
* Tried but failed to fix `cargo build` complaint about unused #[macro use]. See also 7a803a8dc1
* Compiler complaints be-gone
* Give sumtree tests method-tagged folder names so they don't overwrite each others' files
Fixes#658
* large updates for mining, fix async mode, will list changes in PR
* reset config and build defaults
* change to difficulty calculations
* tweaking mining params and tests
* tweaking to tests
* including pre-genesis data for difficulty adjustments, adding adjustment scenario tests
* further clarifying next_difficulty function
* moving tests out of consensus.rs
* pow test fix
* changing pre-genesis generation
Since the default value is also embedded in the help string it appears twice in the output from `grin wallet help`. This PR just removes the default from the help string.
* [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
* Making initial sync easier on the eyes:
- display "chain pointers" as: cumulative @ height [hash]
- clarify and line up to make the "pointers" easy to compare
- make every 100th block show info on debug level info, else as before
* 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.
