* Add checkpoint list generation scripts
* Limit the checkpoint block data size
* Limit the checkpoint height gap
* Add Mainnet and Testnet checkpoint lists
* Parse hard-coded checkpoint lists
The lists were generated using the following limits:
- 256 MB spacing, based on block byte size, and
- 2000 blocks.
* Add MIN and MAX for BlockHeight and LockTime
* Remove duplicate test cases
* fix a comment about the minimum lock time
The minimum LockTime::Time is 5 November 1985 00:53:20 UTC, so the first
day that only contains valid times is 6 November 1985 (in all timezones).
Similarly, the maximum LockTime::Time is 7 February 2106 06::28::15 UTC,
so the last day that only contains valid times in all time zones is
5 February 2106.
* fix: Reject checkpoint lists with bad hashes or heights
Reject the all-zeroes hash, because it is the parent hash of the genesis
block, and should never appear in a checkpoint list.
Reject checkpoint heights that are greater than the maximum block
height.
* fix: Resist CheckpointVerifier memory DoS attacks
Allow a maximum of 2 queued blocks at each height, as a tradeoff between
efficient bad block rejection, and memory usage.
Closes#628.
* fix: Make max queued blocks at height equal to fanout
* fix: Just allocate all the capacity upfront
* fix: Use with_capacity(1) and reserve_exact(1)
* Flatten consensus::verify::* to consensus::*
* Move consensus::*::tests into their own files
* Move CheckpointList into its own file
* Move Progress and Target into a types module
QueuedBlock and QueuedBlockList can stay in checkpoint.rs, because
they are tightly coupled to CheckpointVerifier.
Using tower-batch-based async pattern.
Now the Verifier is agnostic of redjubjub SigTypes. Updated tests to
generate sigs of both types and batch verifies the whole batch.
Resolves#407
* Return Poll::Ready(Err(_)) when verification has finished
* Turn checkpoint::init() into CheckpointVerifier::new()
* Accept IntoIterator<...> for CheckpointVerifier::new()
* Add a CheckpointList type
* Replace the state service with oneshot channels.
* Reject redundant checkpoint blocks
* impl Drop for CheckpointVerifier
* Add fields for caching blocks, and managing verify chains.
* Add current checkpoint functions
* Use a checkpoint range
* Get full backtraces with Err::Try
* Add enums for verification progress and target block heights.
* Replace install_tracing() with zebra_test::init()
* Add a test that mixes good and bad blocks
* Add timeouts to the checkpoint test futures
