* 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.
* Re-introduce peer regular ping/pong
* Fix partial header reads. Turns out that on async tcp streams, even a small chunk like a
header can be read partially. So header read needs to rely on our
fixed-up `read_exact`, with an additional boolean to allow yield
when no bytes were read.
* 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)
* [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
* 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

* We do not want to sync with old peers anyway
* Hide cargo compiler warning for unused NoopAdapter and unused test code. Add TODOs
* add total_diff to ping/pong msgs
debug log for total_diff on each ping/pong
* expose peer addr to the handle_payload fn
so we know where it came from
* fix p2p tests for ping
* default to 0 if we cannot read total_difficulty
* updating a connected peer in place
* actually update peer info diff
* fixup p2p tests
A receiving peer trusts the address advertised by a client.
However as we do not have external address detection (and there is
generally no very good way to do that), the address detected by
a peer is the loopback, which is useless. So we attempt to detect
these cases and use the IP detected by the TCP connection while
keeping the advertised port.
Moved the HTTP APIs away from the REST endpoint abstraction and
to simpler Hyper handlers. Re-established all routes as v1.
Changed wallet receiver port to 13415 to avoid a gap in port
numbers.
Finally, rustfmt seems to have ignored specific files arguments,
running on everything.
* Do not send txs and blocks to senders. Keeps a ring buffer of transaction and blocks hashes that a peer has received. Do not send what we've already received.
