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.
Call and Event are both from the pallets, which are AGPL licensed. Accordingly,
they make serai-client AGPL licensed when serai-client must end up MIT
licensed. This creates a MIT-licensed variant of Calls and Events such that
they can be used by serai-client, enabling transitioning it to MIT.
Relevant to https://github.com/serai-dex/serai/issues/337.
Updates off a yanked version of zerocopy, fixing the failing deny CI.
Bites the bullet on windows-sys 0.52. While I was hoping to update everything
at once, unfortunately tokio won't update until March (see
https://github.com/tokio-rs/mio/pull/1725). I don't want to withold these
updates for that long.
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.
The test failures were caused by not inserting any price, causing the first
price to immediately become the oraclized price. While that's not inherently
invalid, suggesting the tests should've been the ones updated, it opens an
exploit where whoever first adds liquidity has the opportunity to set a
ridiculous price and DoS the set. Not oraclizing until we have an entire
period, achieved by inserting 0s during the initial blocks, ensures an open
launch for such discovery.
There's an exploit where the prior set improperly mints coins, the new set
occurs (resetting the oracle), and they immediately deallocate 49.9% of their
coins (which is more than enough to achieve profitability).
Now, anyone in set must wait until after the next set completes to perform any
deallocation, enabling time to halt upon improper mints.
* Update ValidatorSets with a remove_participant call
* Add DkgRemoval, a sign machine for producing the relevant MuSig signatures
* Don't use position-dependent u8s yet Public when removing validators from the DKG
* Add DkgRemovalPreprocess, DkgRemovalShares
Implementation is via a new publish_tributary_tx lambda.
This is code is a copy-pasted mess which will need to be cleaned up.
* Only allow non-removed validators to vote for removals
Otherwise, it's risked that the remaining validators fall below 67% of the
original set.
* Correct publish_serai_tx, which was prior publish_set_keys in practice
This mirrors how Provided TXs handle topics.
Now, instead of managing a global nonce stream, we can use items such as plan
IDs as topics.
This massively benefits re-attempts, as else we'd need a NOP TX to clear unused
nonces.
* Use redb and in Dockerfiles
The motivation for redb was to remove the multiple rocksdb compile times from
CI.
* Correct feature flagging of coordinator and message-queue in Dockerfiles
* Correct message-queue DB type alias
* Use consistent table typing in redb
* Correct rebase artifacts
* Correct removal of binaries feature from message-queue
* Correct processor feature flagging
* Replace redb with parity-db
It still has much better compile times yet doesn't block when creating multiple
transactions. It also is actively maintained and doesn't grow our tree. The MPT
aspects are irrelevant.
* Correct stray Redb
* clippy warning
* Correct txn get
* Use debug builds in our Dockerfiles to reduce CI times
Also enables only spawning the mdns service when debug in the coordinator.
* Correct underflow in processor
Prior undetected due to relase builds not having bounds checks enabled.
* Restore Serai release due to CI/RPC failures caused by compiling it in debug mode
This is *probably* worth an issue filed upstream, if it can be tracked down.
* Correct failing debug asserts in Monero
These debug asserts assumed there was a change address to take the remainder.
If there's no change address, the remainder is shunted to the fee, causing the
fee to be distinct from the estimate.
We presumably need to modify monero-serai such that change: None isn't valid,
and users must use Change::Fingerprintable(None).
* 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
* Remove NetworkId from processor-messages
Because intent binds to the sender/receiver, it's not needed for intent.
The processor knows what the network is.
The coordinator knows which to use because it's sending this message to the
processor for that network.
Also removes the unused zeroize.
* ProcessorMessage::Completed use Session instead of key
* Move SubstrateSignId to Session
* Finish replacing key with session
* Move message-queue to a fully binary representation
Additionally adds a timeout to the message queue test.
* coordinator clippy
* Remove contention for the message-queue socket by using per-request sockets
* clippy
For some reason, these constantly failed for me while waiting for the key pair
to confirm. This adds a sleep during the mining process, to ensure blocks
actually have time between them, and mines several more blocks to handle the
median code recently added.
Monero doesn't assert the time increases with each block, solely that it
doesn't decrease. Now, the block number is added to the time to ensure it
increases.
processor isn't intended to be used as a library, yet serai-processor-tests
does pull it in as a lib. This caused serai-processor-tests to need to compile
rocksdb, which added multiple minutes to the compilation time.
* Add SignalsConfig to chain_spec
* Correct multiexp feature flagging for rand_core std
* Remove bincode for borsh
Replaces a non-canonical encoding with a canonical encoding which additionally
should be faster.
Also fixes an issue where we used bincode in transcripts where it cannot be
trusted.
This ended up fixing a myriad of other bugs observed, unfortunately.
Accordingly, it either has to be merged or the bug fixes from it must be ported
to a new PR.
* Make serde optional, minimize usage
* Make borsh an optional dependency of substrate/ crates
* Remove unused dependencies
* Use [u8; 64] where possible in the processor messages
* Correct borsh feature flagging
Relevant to #394.
Prevents hand-over due to hand-over occurring via a `Batch` publication.
Expects a new protocol to restore functionality (after a retirement of the
current protocol).
