* Bump up crates versions
* Finally add a Cargo.lock to avoid dependency breakages
* Build doc update for testnet2
* Fix test framework not really using its mining config
* Testnet2 genesis, best so far at 128 difficulty (a nice number)
* Minor build doc update
* 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
* added global slog instance, changed all logging macro formats to include logger instance
* adding configuration to logging, allowing for multiple log outputs
* updates to test, changes to build docs
* rustfmt
* moving logging functions into util crate
* Integrate PMMR and its persistent backend with the Chain
* Chain can set tree roots; PMMR backend discard
* Check spent and prune for each input in new block
* Handling of forks by rewinding the state
* More PMMR tests and fixes, mostly around rewind
* Rewrite get_unspent to use the sumtrees, fix remaining compilation issues
* Base MMR storage structures
Implementations of the MMR append-only file structure and its
remove log. The append-only file is backed by a mmap for read
access. The remove log is stored in memory for quick checking
and backed by a simple file to persist it.
* Add PMMR backend buffer, make PMMR Backend mutable
* The Backend trait now has &mut self methods, and an &mut
reference in PMMR. This simplifies the implementation of all
backends by not forcing them to be interior mutable. Slight
drawback is that a backend can't be used directly as long as it's
used by a PMMR instance.
* Introduced a buffer in the PMMR persistent backend to allow
reads before the underlying files are fully flushed. Implemented
with a temporary VecBackend.
* Implement a prune list to use with dense backends
The PruneList is useful when implementing compact backends for a PMMR (for
example a single large byte array or a file). As nodes get pruned and
removed from the backend to free space, the backend will get more compact
but positions of a node within the PMMR will not match positions in the
backend storage anymore. The PruneList accounts for that mismatch and does
the position translation.
* PMMR store compaction
Implement actual pruning of the underlying PMMR storage by
flushing the remove log. This triggers a rewrite of the PMMR nodes
data (hashes and sums), removing pruned nodes. The information of
what has been removed is kept in a prune list and the remove log
is truncated.
* PMMR store pruning tests and fixes
* Adding ability to serialise parts of the header, pre-nonce and post-nonce
* Some test integration of queueing functions in cuckoo-miner
* more cuckoo-miner async mode integration, now more or less working
* integrating async miner workflow
* rocksdb update
* u64 internal difficulty representation, and integration of latest Cuckoo-miner API
* change to cuckoo-miner notify function
* Issue in testing, and if use_async value is None in grin.toml
* making async mode explicit in tests - 2
* fiddle with port numbers for CI
* update tag to ensure cuckoo-miner build doesn't fail on windows
* change the order in which tests are run
* Starting to refactor test, adding http post to wallet sender
* Implemented ability to run servers on different ports (mostly for testing), and implemented ability to post http requests directly to receiving wallets
* Adding detailed instructions on running multiple servers on the same machine
* Changes to build.doc to outline server running process
* Removed unwanted debug statements
* WIP Local server testing framework evolution
* More refactoring of server pool, checked in because there's a problem
* Added server reference structure, and ability to return server references from tests cleanly
* Added simulate_parallel_mining test, which puts some artificial slowdown into test mining loops, and the difficulty can currently be watched in the log
* Removing the ServerRef structure placed in earlier and replaced with a ServerStats structure, that just returns relevant info about the Server state without exposing it to the world
Builds codecs to encode and decode blocks, block headers, transactions, kernels, etc. Will be used by the store and peer-to-peer layer for serialization, but also to compute hashes. Separates out serialization from core.
