* Route validators for any active set through sc-authority-discovery
Additionally adds an RPC route to retrieve their P2P addresses.
* Have the coordinator get peers from substrate
* Have the RPC return one address, not up to 3
Prevents the coordinator from believing it has 3 peers when it has one.
* Add missing feature to serai-client
* Correct network argument in serai-client for p2p_validators call
* Add a test in serai-client to check DHT population with a much quicker failure than the coordinator tests
* Update to latest Substrate
Removes distinguishing BABE/AuthorityDiscovery keys which causes
sc_authority_discovery to populate as desired.
* Update to a properly tagged substrate commit
* Add all dialed to peers to GossipSub
* cargo fmt
* Reduce common code in serai-coordinator-tests with amore involved new_test
* Use a recursive async function to spawn `n` DockerTests with the necessary networking configuration
* Merge UNIQUE_ID and ONE_AT_A_TIME
* Tidy up the new recursive code in tests/coordinator
* Use a Mutex in CONTEXT to let it be set multiple times
* Make complimentary edits to full-stack tests
* Augment coordinator P2p connection logs
* Drop lock acquisitions before recursing
* Better scope lock acquisitions in full-stack, preventing a deadlock
* Ensure OUTER_OPS is reset across the test boundary
* Add cargo deny allowance for dockertest fork
* Make it clear not providing a change address is fingerprintable
When no change address is provided, all change is shunted to the
fee. This PR makes it clear to the caller that it is fingerprintable
when the caller does this.
* Review comments
Uses a full-fledged serai-abi to do so.
Removes use of UncheckedExtrinsic as a pointlessly (for us) length-prefixed
block with a more complicated signing algorithm than advantageous.
In the future, we should considering consolidating the various primitives
crates. I'm not convinced we benefit from one primitives crate per pallet.
They're a bit more binding, smaller, provided by the Rust bitcoin library,
sane, and we don't have to worry about malleability since all of our inputs are
SegWit.
* Remove subxt
Removes ~20 crates from our Cargo.lock.
Removes downloading the metadata and enables removing the getMetadata RPC route
(relevant to #379).
Moves forward #337.
Done now due to distinctions in the subxt 0.32 API surface which make it
justifiable to not update.
* fmt, update due to deny triggering on a yanked crate
* Correct the handling of substrate_block_notifier now that it's ephemeral, not long-lived
* Correct URL in tests/coordinator from ws to http
* Add a function to deterministically decide which Serai blocks should be co-signed
Has a 5 minute latency between co-signs, also used as the maximal latency
before a co-sign is started.
* Get all active tributaries we're in at a specific block
* Add and route CosignSubstrateBlock, a new provided TX
* Split queued cosigns per network
* Rename BatchSignId to SubstrateSignId
* Add SubstrateSignableId, a meta-type for either Batch or Block, and modularize around it
* Handle the CosignSubstrateBlock provided TX
* Revert substrate_signer.rs to develop (and patch to still work)
Due to SubstrateSigner moving when the prior multisig closes, yet cosigning
occurring with the most recent key, a single SubstrateSigner can be reused.
We could manage multiple SubstrateSigners, yet considering the much lower
specifications for cosigning, I'd rather treat it distinctly.
* Route cosigning through the processor
* Add note to rename SubstrateSigner post-PR
I don't want to do so now in order to preserve the diff's clarity.
* Implement cosign evaluation into the coordinator
* Get tests to compile
* Bug fixes, mark blocks without cosigners available as cosigned
* Correct the ID Batch preprocesses are saved under, add log statements
* Create a dedicated function to handle cosigns
* Correct the flow around Batch verification/queueing
Verifying `Batch`s could stall when a `Batch` was signed before its
predecessors/before the block it's contained in was cosigned (the latter being
inevitable as we can't sign a block containing a signed batch before signing
the batch).
Now, Batch verification happens on a distinct async task in order to not block
the handling of processor messages. This task is the sole caller of verify in
order to ensure last_verified_batch isn't unexpectedly mutated.
When the processor message handler needs to access it, or needs to queue a
Batch, it associates the DB TXN with a lock preventing the other task from
doing so.
This lock, as currently implemented, is a poor and inefficient design. It
should be modified to the pattern used for cosign management. Additionally, a
new primitive of a DB-backed channel may be immensely valuable.
Fixes a standing potential deadlock and a deadlock introduced with the
cosigning protocol.
* Working full-stack tests
After the last commit, this only required extending a timeout.
* Replace "co-sign" with "cosign" to make finding text easier
* Update the coordinator tests to support cosigning
* Inline prior_batch calculation to prevent panic on rotation
Noticed when doing a final review of the branch.
The prior system spawned a new connection per request to enable parallelism,
yet kept hitting hyper::IncompleteMessages I couldn't track down. This
attempts to resolve those by a long-lived socket.
Halves the amount of requests per-authenticated RPC call, and accordingly is
likely still better overall.
I don't believe this is resolved yet but this is still worth pushing.
* Updates to modern dockertest
* More updates to latest dockertest
* Update Cargo.lock to dockertest with handle restored
* clippy coordinator tests
* clippy full-stack tests
* Remove kayabaNerve branch for official repo's latest commit hash
* Update serai-client, remove reliance on the existence of a handle fn
* Don't use the hex encoding of unique_id in dockertests
Gets our hostnames just below 64 bytes, resolving test failures on at least
Debian-based systems.
* Use Network::Isolated for all dockertest instances
* Correct error from prior commit's edits
* initial implementation
* add function to get a balance of an account
* add support for multiple coins
* rename pallet to "coins-pallet"
* replace balances, assets and tokens pallet with coins pallet in runtime
* add total supply info
* update client side for new Coins pallet
* handle fees
* bug fixes
* Update FeeAccount test

Fixes where ram_scanned is updated in processor. The prior version, while safe,
would redo massive amounts of work during periods of inactivity. It also hit an
undocumented invariant where get_eventuality_completions assumes new blocks,
yet redone work wouldn't have new blocks.
Modifies Monero's generate_blocks to return the hashes of the generated blocks.
