Moves from concatted Dockerfiles to pseudo-templated Dockerfiles via a dedicated Rust program.
Removes the unmaintained kubernetes, not because we shouldn't have/use it, but because it's unmaintained and needs to be reworked before it's present again.
Replaces the compose with the work in the new orchestrator binary which spawns everything as expected. While this arguably re-invents the wheel, it correctly manages secrets and handles the variadic Dockerfiles.
Also adds an unrelated patch for zstd and simplifies running services a bit by greater utilizing the existing infrastructure.
---
* Delete all Dockerfile fragments, add new orchestator to generate Dockerfiles
Enables greater templating.
Also delete the unmaintained kubernetes folder *for now*. This should be
restored in the future.
* Use Dockerfiles from the orchestator
* Ignore Dockerfiles in the git repo
* Remove CI job to check Dockerfiles are as expected now that they're no longer committed
* Remove old Dockerfiles from repo
* Use Debian for monero-wallet-rpc
* Remove replace_cmds for proper usage of entry-dev
Consolidates ports a bit.
Updates serai-docker-tests from "compose" to "build".
* Only write a new dockerfile if it's distinct
Preserves the updated time metadata.
* Update serai-docker-tests
* Correct the path Dockerfiles are built from
* Correct inclusion of orchestration folder in Docker builds
* Correct debug/release flagging in the cargo command
Apparently, --debug isn't an effective NOP yet an error.
* Correct path used to run the Serai node within a Dockerfile
* Correct path in Monero Dockerfile
* Attempt storing monerod in /usr/bin
* Use sudo to move into /usr/bin in CI
* Correct 18.3.0 to 18.3.1
* Escape * with quotes
* Update deny.toml, ADD orchestration in runtime Dockerfile
* Add --detach to the Monero GH CI
* Diversify dockerfiles by network
* Fixes to network-diversified orchestration
* Bitcoin and Monero testnet scripts
* Permissions and tweaks
* Flatten scripts folders
* Add missing folder specification to Monero Dockerfile
* Have monero-wallet-rpc specify the monerod login
* Have the Docker CMD specify env variables inserted at time of Dockerfile generation
They're overrideable with the global enviornment as for tests. This enables
variable generation in orchestrator and output to productionized Docker files
without creating a life-long file within the Docker container.
* Don't add Dockerfiles into Docker containers now that they have secrets
Solely add the source code for them as needed to satisfy the workspace bounds.
* Download arm64 Monero on arm64
* Ensure constant host architecture when reproducibly building the wasm
Host architecture, for some reason, can effect the generated code despite the
target architecture always being foreign to the host architecture.
* Randomly generate infrastructure keys
* Have orchestrator generate a key, be able to create/start containers
* Ensure bash is used over sh
* Clean dated docs
* Change how quoting occurs
* Standardize to sh
* Have Docker test build the dev Dockerfiles
* Only key_gen once
* cargo update
Adds a patch for zstd and reconciles the breaking nightly change which just
occurred.
* Use a dedicated network for Serai
Also fixes SERAI_HOSTNAME passed to coordinator.
* Support providing a key over the env for the Serai node
* Enable and document running daemons for tests via serai-orchestrator
Has running containers under the dev network port forward the RPC ports.
* Use volumes for bitcoin/monero
* Use bitcoin's run.sh in GH CI
* Only use the volume for testnet (not dev)
* report_slashes plumbing in Substrate
Notably delays the SetRetired event until it provides a slash report or the set
after it becomes the set to report its slashes.
* Add dedicated AcceptedHandover event
* Add SlashReport TX to Tributary
* Create SlashReport TXs
* Handle SlashReport TXs
* Add logic to generate a SlashReport to the coordinator
* Route SlashReportSigner into the processor
* Finish routing the SlashReport signing/TX publication
* Add serai feature to processor's serai-client
* 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
Slight downscope which helps combat the antipattern which is the futures glob
crate. While futures_util is still a large crate, it has better defaults and
is smaller by virtue of not pulling the executor.
* implement general design
* add slashing
* bug fixes
* fix pr comments
* misc fixes
* fix grandpa abi call type
* Correct rebase artifacts I introduced
* Cleanups and corrections
1) Uses vec![] for the OpaqueKeyProof as there's no value to passing it around
2) Remove usage of Babe/Grandpa Offences for tracking if an offence is known
for checking if can slash. If can slash, no prior offence must have been
known.
3) Rename DisabledIndices to SeraiDisabledIndices, drop historical data for
current session only.
4) Doesn't remove from the pre-declared upcoming Serai set upon slash due to
breaking light clients.
5) Into/From instead of AsRef for KeyOwnerProofSystem's generic to ensure
safety of the conversion.
* Correct deduction from TotalAllocatedStake on slash
It should only be done if in set and only with allocations contributing to
TotalAllocatedStake (Allocation + latest session's PendingDeallocation).
* Changes meant for prior commit

* Schedule re-attempts and add a (not filled out) match statement to actually execute them
A comment explains the methodology. To copy it here:
"""
This is because we *always* re-attempt any protocol which had participation. That doesn't
mean we *should* re-attempt this protocol.
The alternatives were:
1) Note on-chain we completed a protocol, halting re-attempts upon 34%.
2) Vote on-chain to re-attempt a protocol.
This schema doesn't have any additional messages upon the success case (whereas
alternative #1 does) and doesn't have overhead (as alternative #2 does, sending votes and
then preprocesses. This only sends preprocesses).
"""
Any signing protocol which reaches sufficient participation will be
re-attempted until it no longer does.
* Have the Substrate scanner track DKG removals/completions for the Tributary code
* Don't keep trying to publish a participant removal if we've already set keys
* Pad out the re-attempt match a bit more
* Have CosignEvaluator reload from the DB
* Correctly schedule cosign re-attempts
* Actuall spawn new DKG removal attempts
* Use u32 for Batch ID in SubstrateSignableId, finish Batch re-attempt routing
The batch ID was an opaque [u8; 5] which also included the network, yet that's
redundant and unhelpful.
* Clarify a pair of TODOs in the coordinator
* Remove old TODO
* Final comment cleanup
* Correct usage of TARGET_BLOCK_TIME in reattempt scheduler
It's in ms and I assumed it was in s.
* Have coordinator tests drop BatchReattempts which aren't relevant yet may exist
* Bug fix and pointless oddity removal
We scheduled a re-attempt upon receiving 2/3rds of preprocesses and upon
receiving 2/3rds of shares, so any signing protocol could cause two re-attempts
(not one more).
The coordinator tests randomly generated the Batch ID since it was prior an
opaque byte array. While that didn't break the test, it was pointless and did
make the already-succeeded check before re-attempting impossible to hit.
* Add log statements, correct dead-lock in coordinator tests
* Increase pessimistic timeout on recv_message to compensate for tighter best-case timeouts
* Further bump timeout by a minute
AFAICT, GH failed by just a few seconds.
This also is worst-case in a single instance, making it fine to be decently long.
* Further further bump timeout due to lack of distinct error
* Move logic for evaluating if a cosign should occur to its own file
Cleans it up and makes it more robust.
* Have expected_next_batch return an error instead of retrying
While convenient to offer an error-free implementation, it potentially caused
very long lived lock acquisitions in handle_processor_message.
* Unify and clean DkgConfirmer and DkgRemoval
Does so via adding a new file for the common code, SigningProtocol.
Modifies from_cache to return the preprocess with the machine, as there's no
reason not to. Also removes an unused Result around the type.
Clarifies the security around deterministic nonces, removing them for
saved-to-disk cached preprocesses. The cached preprocesses are encrypted as the
DB is not a proper secret store.
Moves arguments always present in the protocol from function arguments into the
struct itself.
Removes the horribly ugly code in DkgRemoval, fixing multiple issues present
with it which would cause it to fail on use.
* Set SeraiBlockNumber in cosign.rs as it's used by the cosigning protocol
* Remove unnecessary Clone from lambdas in coordinator
* Remove the EventDb from Tributary scanner
We used per-Transaction DB TXNs so on error, we don't have to rescan the entire
block yet only the rest of it. We prevented scanning multiple transactions by
tracking which we already had.
This is over-engineered and not worth it.
* Implement borsh for HasEvents, removing the manual encoding
* Merge DkgConfirmer and DkgRemoval into signing_protocol.rs
Fixes a bug in DkgConfirmer which would cause it to improperly handle indexes
if any validator had multiple key shares.
* Strictly type DataSpecification's Label
* Correct threshold_i_map_to_keys_and_musig_i_map
It didn't include the participant's own index and accordingly was offset.
* Create TributaryBlockHandler
This struct contains all variables prior passed to handle_block and stops them
from being passed around again and again.
This also ensures fatal_slash is only called while handling a block, as needed
as it expects to operate under perfect consensus.
* Inline accumulate, store confirmation nonces with shares
Inlining accumulate makes sense due to the amount of data accumulate needed to
be passed.
Storing confirmation nonces with shares ensures that both are available or
neither. Prior, one could be yet the other may not have been (requiring an
assert in runtime to ensure we didn't bungle it somehow).
* Create helper functions for handling DkgRemoval/SubstrateSign/Sign Tributary TXs
* Move Label into SignData
All of our transactions which use SignData end up with the same common usage
pattern for Label, justifying this.
Removes 3 transactions, explicitly de-duplicating their handlers.
* Remove CurrentlyCompletingKeyPair for the non-contextual DkgKeyPair
* Remove the manual read/write for TributarySpec for borsh
This struct doesn't have any optimizations booned by the manual impl. Using
borsh reduces our scope.
* Use temporary variables to further minimize LoC in tributary handler
* Remove usage of tuples for non-trivial Tributary transactions
* Remove serde from dkg
serde could be used to deserialize intenrally inconsistent objects which could
lead to panics or faults.
The BorshDeserialize derives have been replaced with a manual implementation
which won't produce inconsistent objects.
* Abstract Future generics using new trait definitions in coordinator
* Move published_signed_transaction to tributary/mod.rs to reduce the size of main.rs
* Split coordinator/src/tributary/mod.rs into spec.rs and transaction.rs
Event retrieval was prior:
- Retrieve all events in the block, which may be hundreds of KB
- Filter to just a few
Since it's frequent to want multiple sets of events, each filtered in their own
way, this caused the retrieval to happen multiple times. Now, it only will
happen once.
Also has the scoped clients take a reference, not an owned TemporalSerai.
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.
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
* 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
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).
