If not, see . +//! This file contains the Nakamoto block downloader implementation. +//! +//! # Overview +//! +//! The downloader is implemented as a network state machine, which is called from the main event +//! loop of the p2p network. On each pass, the downloader state machine inspects the Stacks chain +//! state and peer block inventories to see if there are any tenures to download, and if so, it +//! queues up HTTP requests for the blocks and reacts to their responses. It yields the downloaded +//! blocks, which the p2p main loop yields in its `NetworkResult` for the relayer to consume. +//! +//! # Design +//! +//! The state machine has three layers: a top-level state machine for obtaining managing all of +//! the requisite state for identifying tenures to download, a pair of low-level state machines for +//! fetching individual tenures, and a middle layer for using the tenure data to drive the low-level +//! state machiens to fetch the requisite tenures. +//! +//! The three-layer design is meant to provide a degree of encapsulation of each downloader +//! concern. Because downloading tenures is a multi-step process, we encapsulate the steps to +//! download a single tenure into a low-level state machine which can be driven by separate +//! flow-control. Because we can drive multiple tenure downloads in parallel (i.e. one per peer), +//! we have a middle layer for scheduling tenures to peers for download. This middle layer manages +//! the lifecycles of the lower layer state machines. The top layer is needed to interface the +//! middle layer to the chainstate and the rest of the p2p network, and as such, handles the +//! bookkpeeing so that the lower layers can operate without needing access to this +//! otherwise-unrelated concern. +//! +//! ## NakamotoDownloadStateMachine +//! +//! The top-level download state machine (`NakamotoDownloadStateMachine`) has two states: +//! Obtaining confirmed tenures, and obtaining unconfirmed tenures. A _confirmed_ tenure is a +//! tenure for which we can obtain the start and end block hashes using peer inventories and the +//! sortition DB. The hashes are embedded within sortition winners, and the inventories tell us +//! which sortitions correspond to tenure-starts and tenure-ends (each tenure-end is the +//! tenure-start of the next tenure). An _unconfirmed_ tenure is a tenure that is not confirmed -- +//! we do not have one or both of its start/end block hashes available from the sortition history +//! since they have not been recorded yet. +//! +//! The `NakamotoDownloadStateMachine` operates by attempting to download each reward cycle's +//! tenures, including the current reward cycle. Once it has obtained them all for the current +//! reward cycle, it proceeds to fetch the next reward cycle's tenures. It does this because the +//! sortition DB itself cannot inform us of the tenure start/end block hashes in a given reward +//! cycle until the PoX anchor block mined in the previous reward cycle has been downloaded and +//! processed. +//! +//! To achieve this, the `NakamotoDwonloadStateMachine` performs a lot of bookkeeping. Namely, it +//! keeps track of: +//! +//! * The ongoing and prior reward cycle's sortitions' tenure IDs and winning block hashes +//! (implemented as lists of `WantedTenure`s) +//! * Which sortitions corresponds to tenure start and end blocks (implemented as a table of +//! `TenureStartEnd`s) +//! * Which neighbors can serve which full tenures +//! * What order to request tenures in +//! +//! This information is consumed by the lower levels of the state machine. +//! +//! ## `NakamotoTenureDownloadSet` +//! +//! Naturally, the `NakamotoDownloadStateMachine` contains two code paths -- one for each mode. +//! To facilitate confirmeed tenure downloads, it has a second-layer state machine called +//! the `NakamotoTenureDownloadSet`. This is responsible for identifying and issuing requests to +//! peers which can serve complete tenures, and keeping track of whether or not the current reward +//! cycle has any remaining tenures to download. To facilitate unconfirmed tenure downloads (which +//! is a much simpler task), it simply provides an internal method for issuing requests and +//! processing responses for its neighbors' unconfirmed tenure data. +//! +//! This middle layer consumes the data mantained by the `NakamotoDownloaderStateMachine` in order +//! to instantiate, drive, and clean up one or more per-tenure download state machines. +//! +//! ## NakamotoTenureDownloader and `NakamotoUnconfirmedTenureDownloader` +//! +//! Per SIP-021, obtaining a confirmed tenure is a multi-step process. To carry this out, this +//! module contains two third-level state machines: `NakamotoTenureDownloader`, which downloads a +//! single tenure's blocks if the start and end block hash are known, and +//! `NakamotoUnconfirmedTenureDownloader`, which downloads the ongoing tenure. The +//! `NakamotoTenureDownloadSet` uses a set of `NakamotoTenureDownloader` instances (one per +//! neighbor) to fetch confirmed tenures, and the `NakamotoDownloadStateMachine`'s unconfirmed +//! tenure download state provides a method for driving a set of +//! `NakamotoUnconfirmedTenureDownloader` machines to poll neighbors for their latest tenure +//! blocks. +//! +//! # Implementation +//! +//! The implementation here plugs directly into the p2p state machine, and is called once per pass. +//! Unlike in Stacks 2.x, the downloader is consistently running, and can act on newly-discovered +//! tenures once a peer's inventory reports their availability. This is because Nakamoto is more +//! latency-sensitive than Stacks 2.x, and nodes need to obtain blocks as quickly as possible. +//! +//! Concerning latency, a lot of attention is paid to reducing the amount of gratuitous I/O +//! required for the state machine to run. The bookkeeping steps in the +//! `NakamotoDownloadStateMachine` may seem tedious, but they are specifically designed to only +//! load new sortition and chainstate data when it is necessary to do so. Most of the time, the +//! downloader never touches disk; it only needs to do so when it is considering new sortitions and +//! new chain tips. + use std::collections::{BTreeMap, HashMap, HashSet, VecDeque}; use std::convert::TryFrom; use std::fmt; @@ -62,16 +158,24 @@ use crate::net::server::HttpPeer; use crate::net::{Error as NetError, Neighbor, NeighborAddress, NeighborKey}; use crate::util_lib::db::{DBConn, Error as DBError}; -/// Download states for an historic tenure +/// Download states for an historic tenure.

Sep 17 00:00:00 2001 From: Aaron Blankstein Date: Thu, 14 Mar 2024 09:41:49 -0500 Subject: [PATCH 092/182] feat: naka miner acts as signer set coordinator during block signing * Replaces msg_id u32 with an enum for message identification * Adds an additional slot for miner messages * Adds a sync channel for listening to StackerDB events * Adds a StackerDBs method for pushing a chunk locally and emitting event * Uses a new message type to store DKG results, to be read by miners to instantiate coordinator * Uses a test signing channel for nakamoto integration tests * Currently builds with a

The fix for this is to ignore attempts to store duplicate blocks. --- stackslib/src/burnchains/bitcoin/indexer.rs | 6 +- stackslib/src/burnchains/db.rs | 16 +- stackslib/src/chainstate/coordinator/mod.rs | 2 +- .../stacks-node/src/tests/bitcoin_regtest.rs | 30 +++- .../src/tests/neon_integrations.rs | 138 +++++++++++++++++- 5 files changed, 183 insertions(+), 9 deletions(-) diff --git a/stackslib/src/burnchains/bitcoin/indexer.rs b/stackslib/src/burnchains/bitcoin/indexer.rs index c273a38de4..ed0e89e0cc 100644 --- a/stackslib/src/burnchains/bitcoin/indexer.rs +++ b/stackslib/src/burnchains/bitcoin/indexer.rs @@ -837,7 +837,11 @@ impl BitcoinIndexer { } } else { // ignore the reorg - test_debug!("Reorg chain does not overtake original Bitcoin chain");

- -
    The Stacks 2.4 Testnet activation height occurred before the finalized [**SIP-024**](https://github.com/stacksgov/sips/tree/main/sips/sip-024) updates and release of the stacks-node versioned 2.4.0.0.0.
-    Blocks mined after testnet BTC block `2,432,545` will all be considered invalid by 2.4.0.0.0 nodes and upgrading Testnet to a release >= `2.4.0.0.0` will require adding some overrides prior to the specified burnchchain block.
-    The stacks-node currently doesn't seamlessly recover from the unexpectedly absent PoX anchor blocks in testnet, so it needs to apply affirmation map overrides using the overrides table:

This file contains the Nakamoto block downloader implementation. -//! -//! # Overview -//! -//! The downloader is implemented as a network state machine, which is called from the main event -//! loop of the p2p network. On each pass, the downloader state machine inspects the Stacks chain -//! state and peer block inventories to see if there are any tenures to download, and if so, it -//! queues up HTTP requests for the blocks and reacts to their responses. It yields the downloaded -//! blocks, which the p2p main loop yields in its `NetworkResult` for the relayer to consume. -//! -//! # Design -//! -//! The state machine has three layers: a top-level state machine for managing all of -//! the requisite state for identifying tenures to download, a pair of low-level state machines for -//! fetching individual tenures, and a middle layer for using the tenure data to drive the low-level -//! state machines to fetch the requisite tenures. -//! -//! The three-layer design is meant to provide a degree of encapsulation of each downloader -//! concern. Because downloading tenures is a multi-step process, we encapsulate the steps to -//! download a single tenure into a low-level state machine which can be driven by separate -//! flow-control. Because we can drive multiple tenure downloads in parallel (i.e. one per peer), -//! we have a middle layer for scheduling tenures to peers for download. This middle layer manages -//! the lifecycles of the lower layer state machines. The top layer is needed to interface the -//! middle layer to the chainstate and the rest of the p2p network, and as such, handles the -//! bookkeeping so that the lower layers can operate without needing access to this -//! otherwise-unrelated concern. -//! -//! ## NakamotoDownloadStateMachine -//! -//! The top-level download state machine (`NakamotoDownloadStateMachine`) has two states: -//! Obtaining confirmed tenures, and obtaining unconfirmed tenures. A _confirmed_ tenure is a -//! tenure for which we can obtain the start and end block hashes using peer inventories and the -//! sortition DB. The hashes are embedded within sortition winners, and the inventories tell us -//! which sortitions correspond to tenure-starts and tenure-ends (each tenure-end is the -//! tenure-start of the next tenure). An _unconfirmed_ tenure is a tenure that is not confirmed -- -//! we do not have one or both of its start/end block hashes available from the sortition history -//! since they have not been recorded yet. -//! -//! The `NakamotoDownloadStateMachine` operates by attempting to download each reward cycle's -//! tenures, including the current reward cycle. Once it has obtained them all for the current -//! reward cycle, it proceeds to fetch the next reward cycle's tenures. It does this because the -//! sortition DB itself cannot inform us of the tenure start/end block hashes in a given reward -//! cycle until the PoX anchor block mined in the previous reward cycle has been downloaded and -//! processed. -//! -//! To achieve this, the `NakamotoDwonloadStateMachine` performs a lot of bookkeeping. Namely, it -//! keeps track of: -//! -//! * The ongoing and prior reward cycle's sortitions' tenure IDs and winning block hashes -//! (implemented as lists of `WantedTenure`s) -//! * Which sortitions correspond to tenure start and end blocks (implemented as a table of -//! `TenureStartEnd`s) -//! * Which neighbors can serve which full tenures -//! * What order to request tenures in -//! -//! This information is consumed by the lower levels of the state machine. -//! -//! ## `NakamotoTenureDownloadSet` -//! -//! Naturally, the `NakamotoDownloadStateMachine` contains two code paths -- one for each mode. -//! To facilitate confirmed tenure downloads, it has a second-layer state machine called -//! the `NakamotoTenureDownloadSet`. This is responsible for identifying and issuing requests to -//! peers which can serve complete tenures, and keeping track of whether or not the current reward -//! cycle has any remaining tenures to download. To facilitate unconfirmed tenure downloads (which -//! is a much simpler task), it simply provides an internal method for issuing requests and -//! processing responses for its neighbors' unconfirmed tenure data. -//! -//! This middle layer consumes the data mantained by the `,akamotoDownloaderStateMachine` in order -//! to instantiate, drive, and clean up one or more per-tenure download state machines. -//! -//! ## `NakamotoTenureDownloader` and `NakamotoUnconfirmedTenureDownloader` -//! -//! Per SIP-021, obtaining a confirmed tenure is a multi-step process. To carry this out, this -//! module contains two third-level state machines: `NakamotoTenureDownloader`, which downloads a -//! single tenure's blocks if the start and end block hash are known, and -//! `NakamotoUnconfirmedTenureDownloader`, which downloads the ongoing tenure. The -//! `NakamotoTenureDownloadSet` uses a set of `NakamotoTenureDownloader` instances (one per -//! neighbor) to fetch confirmed tenures, and the `NakamotoDownloadStateMachine`'s unconfirmed -//! tenure download state provides a method for driving a set of -//! `NakamotoUnconfirmedTenureDownloader` machines to poll neighbors for their latest tenure -//! blocks. -//! -//! # Implementation -//! -//! The implementation here plugs directly into the p2p state machine, and is called once per pass. -//! Unlike in Stacks 2.x, the downloader is consistently running, and can act on newly-discovered -//! tenures once a peer's inventory reports their availability. This is because Nakamoto is more -//! latency-sensitive than Stacks 2.x, and nodes need to obtain blocks as quickly as possible. -//! -//! Concerning latency, a lot of attention is paid to reducing the amount of gratuitous I/O -//! required for the state machine to run. The bookkeeping steps in the -//! `NakamotoDownloadStateMachine` may seem tedious, but they are specifically designed to only -//! load new sortition and chainstate data when it is necessary to do so. Most of the time, the -//! downloader never touches disk; it only needs to do so when it is considering new sortitions and -//! new chain tips. - -use std::collections::{BTreeMap, HashMap, HashSet, VecDeque}; -use std::convert::TryFrom; -use std::fmt; -use std::hash::{Hash, Hasher}; -use std::io::{Read, Write}; -use std::net::{IpAddr, SocketAddr}; -use std::time::{Duration, Instant}; - -use rand::seq::SliceRandom; -use rand::{thread_rng, RngCore}; -use stacks_common::types::chainstate::{ - BlockHeaderHash, ConsensusHash, PoxId, SortitionId, StacksBlockId, -}; -use stacks_common::types::net::{PeerAddress, PeerHost}; -use stacks_common::types::StacksEpochId; -use stacks_common::util::hash::to_hex; -use stacks_common::util::secp256k1::{Secp256k1PrivateKey, Secp256k1PublicKey}; -use stacks_common::util::{get_epoch_time_ms, get_epoch_time_secs, log}; -use wsts::curve::point::Point; - -use crate::burnchains::{Burnchain, BurnchainView, PoxConstants}; -use crate::chainstate::burn::db::sortdb::{ - BlockHeaderCache, SortitionDB, SortitionDBConn, SortitionHandleConn, -}; -use crate::chainstate::burn::BlockSnapshot; -use crate::chainstate::nakamoto::{ - NakamotoBlock, NakamotoBlockHeader, NakamotoChainState, NakamotoStagingBlocksConnRef, -}; -use crate::chainstate::stacks::db::StacksChainState; -use crate::chainstate::stacks::{ - Error as chainstate_error, StacksBlockHeader, TenureChangePayload, -}; -use crate::core::{ - EMPTY_MICROBLOCK_PARENT_HASH, FIRST_BURNCHAIN_CONSENSUS_HASH, FIRST_STACKS_BLOCK_HASH, -}; -use crate::net::api::gettenureinfo::RPCGetTenureInfo; -use crate::net::chat::ConversationP2P; -use crate::net::db::{LocalPeer, PeerDB}; -use crate::net::http::HttpRequestContents; -use crate::net::httpcore::{StacksHttpRequest, StacksHttpResponse}; -use crate::net::inv::epoch2x::InvState; -use crate::net::inv::nakamoto::{NakamotoInvStateMachine, NakamotoTenureInv}; -use crate::net::neighbors::rpc::NeighborRPC; -use crate::net::neighbors::NeighborComms; -use crate::net::p2p::PeerNetwork; -use crate::net::server::HttpPeer; -use crate::net::{Error as NetError, Neighbor, NeighborAddress, NeighborKey}; -use crate::util_lib::db::{DBConn, Error as DBError}; - -/// Download states for an historic tenure.

This file contains the Nakamoto block downloader implementation. +//! +//! # Overview +//! +//! The downloader is implemented as a network state machine, which is called from the main event +//! loop of the p2p network. On each pass, the downloader state machine inspects the Stacks chain +//! state and peer block inventories to see if there are any tenures to download, and if so, it +//! queues up HTTP requests for the blocks and reacts to their responses. It yields the downloaded +//! blocks, which the p2p main loop yields in its `NetworkResult` for the relayer to consume. +//! +//! # Design +//! +//! The state machine has three layers: a top-level state machine for managing all of +//! the requisite state for identifying tenures to download, a pair of low-level state machines for +//! fetching individual tenures, and a middle layer for using the tenure data to drive the low-level +//! state machines to fetch the requisite tenures. +//! +//! The three-layer design is meant to provide a degree of encapsulation of each downloader +//! concern. Because downloading tenures is a multi-step process, we encapsulate the steps to +//! download a single tenure into a low-level state machine which can be driven by separate +//! flow-control. Because we can drive multiple tenure downloads in parallel (i.e. one per peer), +//! we have a middle layer for scheduling tenures to peers for download. This middle layer manages +//! the lifecycles of the lower layer state machines. The top layer is needed to interface the +//! middle layer to the chainstate and the rest of the p2p network, and as such, handles the +//! bookkeeping so that the lower layers can operate without needing access to this +//! otherwise-unrelated concern. +//! +//! ## NakamotoDownloadStateMachine +//! +//! The top-level download state machine (`NakamotoDownloadStateMachine`) has two states: +//! Obtaining confirmed tenures, and obtaining unconfirmed tenures. A _confirmed_ tenure is a +//! tenure for which we can obtain the start and end block hashes using peer inventories and the +//! sortition DB. The hashes are embedded within sortition winners, and the inventories tell us +//! which sortitions correspond to tenure-starts and tenure-ends (each tenure-end is the +//! tenure-start of the next tenure). An _unconfirmed_ tenure is a tenure that is not confirmed -- +//! we do not have one or both of its start/end block hashes available from the sortition history +//! since they have not been recorded yet. +//! +//! The `NakamotoDownloadStateMachine` operates by attempting to download each reward cycle's +//! tenures, including the current reward cycle. Once it has obtained them all for the current +//! reward cycle, it proceeds to fetch the next reward cycle's tenures. It does this because the +//! sortition DB itself cannot inform us of the tenure start/end block hashes in a given reward +//! cycle until the PoX anchor block mined in the previous reward cycle has been downloaded and +//! processed. +//! +//! To achieve this, the `NakamotoDwonloadStateMachine` performs a lot of bookkeeping. Namely, it +//! keeps track of: +//! +//! * The ongoing and prior reward cycle's sortitions' tenure IDs and winning block hashes +//! (implemented as lists of `WantedTenure`s) +//! * Which sortitions correspond to tenure start and end blocks (implemented as a table of +//! `TenureStartEnd`s) +//! * Which neighbors can serve which full tenures +//! * What order to request tenures in +//! +//! This information is consumed by the lower levels of the state machine. +//! +//! ## `NakamotoTenureDownloadSet` +//! +//! Naturally, the `NakamotoDownloadStateMachine` contains two code paths -- one for each mode. +//! To facilitate confirmed tenure downloads, it has a second-layer state machine called +//! the `NakamotoTenureDownloadSet`. This is responsible for identifying and issuing requests to +//! peers which can serve complete tenures, and keeping track of whether or not the current reward +//! cycle has any remaining tenures to download. To facilitate unconfirmed tenure downloads (which +//! is a much simpler task), it simply provides an internal method for issuing requests and +//! processing responses for its neighbors' unconfirmed tenure data. +//! +//! This middle layer consumes the data mantained by the `,akamotoDownloaderStateMachine` in order +//! to instantiate, drive, and clean up one or more per-tenure download state machines. +//! +//! ## `NakamotoTenureDownloader` and `NakamotoUnconfirmedTenureDownloader` +//! +//! Per SIP-021, obtaining a confirmed tenure is a multi-step process. To carry this out, this +//! module contains two third-level state machines: `NakamotoTenureDownloader`, which downloads a +//! single tenure's blocks if the start and end block hash are known, and +//! `NakamotoUnconfirmedTenureDownloader`, which downloads the ongoing tenure. The +//! `NakamotoTenureDownloadSet` uses a set of `NakamotoTenureDownloader` instances (one per +//! neighbor) to fetch confirmed tenures, and the `NakamotoDownloadStateMachine`'s unconfirmed +//! tenure download state provides a method for driving a set of +//! `NakamotoUnconfirmedTenureDownloader` machines to poll neighbors for their latest tenure +//! blocks. +//! +//! # Implementation +//! +//! The implementation here plugs directly into the p2p state machine, and is called once per pass. +//! Unlike in Stacks 2.x, the downloader is consistently running, and can act on newly-discovered +//! tenures once a peer's inventory reports their availability. This is because Nakamoto is more +//! latency-sensitive than Stacks 2.x, and nodes need to obtain blocks as quickly as possible. +//! +//! Concerning latency, a lot of attention is paid to reducing the amount of gratuitous I/O +//! required for the state machine to run. The bookkeeping steps in the +//! `NakamotoDownloadStateMachine` may seem tedious, but they are specifically designed to only +//! load new sortition and chainstate data when it is necessary to do so.
