* Util to zip and unzip directories
* First pass at sumtree request/response. Add message types, implement the exchange in the protocol, zip up the sumtree directory and stream the file over, with necessary adapter hooks.
* Implement the sumtree archive receive logicGets the sumtree archive data stream from the network and write it to a file. Unzip the file, place it at the right spot and reconstruct the sumtree data structure, rewinding where to the right spot.
* Sumtree hash structure validation
* Simplify sumtree backend buffering logic. The backend for a sumtree has to implement some in-memory buffering logic to provide a commit/rollback interface. The backend itself is an aggregate of 3 underlying storages (an append only file, a remove log and a skip list). The buffering was previously implemented both by the backend and some of the underlying storages. Now pushing back all buffering logic to the storages to keep the backend simpler.
* Add kernel append only store file to sumtrees. The chain sumtrees structure now also saves all kernels to a dedicated file. As that storage is implemented by the append only file wrapper, it's also rewind-aware.
* Full state validation. Checks that:
- MMRs are sane (hash and sum each node)
- Tree roots match the corresponding header
- Kernel signatures are valid
- Sum of all kernel excesses equals the sum of UTXO commitments
minus the supply
* Fast sync handoff to body sync. Once the fast-sync state is fully setup, get bacj in body sync
mode to get the full bodies of the last blocks we're missing.
* First fully working fast sync
* Facility in p2p conn to deal with attachments (raw binary after message).
* Re-introduced sumtree send and receive message handling using the above.
* Fixed test and finished updating all required db state after sumtree validation.
* Massaged a little bit the pipeline orphan check to still work after the new sumtrees have been setup.
* Various cleanup. Consolidated fast sync and full sync into a single function as they're very similar. Proper conditions to trigger a sumtree request and some checks on receiving it.
* first pass at allow/deny lists for hard-coded peers (not just seeds)
* commit
* add peers_allow and peers_deny examples and comments to grin.toml
* always ask for compact block
always fail to hydrate
always fallback to requesting full block
* decide to send full (empty) block over compact (empty) block
* add some randomness to the decision around broadcasting an empty block
as a block or as a compact block (so we can exercise more code paths easily)
* first pass at allow/deny lists for hard-coded peers (not just seeds)
* commit
* add peers_allow and peers_deny examples and comments to grin.toml
* fix build issue with simulnet tests
* fix p2p tests
* [wip] header first propagation
successfully propagating headers (unless we mined the block itself)
not yet asking for the block if we receive a header
* 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
* 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
Moved handling to the peer map out of the p2p server and into
its own struct. Allowed factoring code from the net adapter and
simplification of some interactions. Also removes the need for
the adapter to reference the p2p server or peers.
Fixes#430, #453 and #456
* Very quick peer banning endpoint, helps with #406

* add height to ping/ping

* We do not want to sync with old peers anyway
* Hide cargo compiler warning for unused NoopAdapter and unused test code. Add TODOs
* introduce cpu_pool to read_msg

* expose cpu_pool as part of net_adapter (reuse across all peer connections and handlers)
* fix DummyAdaptor for test usage
* add new() to DummyAdapter for convenience
Added support for peer banning on the p2p server. The peer status
is changed and the peer is disconnected. A banned peer won't be
able to reconnect as well.
Tracking of chain errors due to a block that's intrinsically bad
and banning of the peer that sent it. If we're syncing, resetting
the header chain to the same as the main chain to force
backtracking.
