📝 WalkthroughWalkthroughThis PR refactors task-scheduler integration and APIs: TaskSchedulerService::new signature now accepts an RPC URL and additional runtime args, replacing the TransactionSchedulerHandle with RpcClient usage for sending transactions; TaskSchedulerService and related methods now return TaskSchedulerResult. The scheduler crate's Cargo.toml swaps Solana dependencies (introduces solana-rpc-client, removes pubsub and others) and removes the integration test suite. SchedulerDatabase adds created_at/updated_at columns and public methods now return TaskSchedulerResult. BindAddress helpers for HTTP/websocket URLs were added and a test CPI argument was changed to 0. Possibly related PRs

287-297: RpcClient wiring correctly routes through JSON-RPC for Chainlink, but relies on non-wildcard listen addressesSwitching
TaskSchedulerService::newto useRpcClient::new(config.listen.http())correctly sends crank transactions through the node's JSON-RPC stack (and therefore through Chainlink) instead of hittingTransactionSchedulerdirectly, aligning with #722.However, the current
BindAddress::http()method does not normalize unspecified addresses. Ifconfig.listenis configured as a wildcard bind (e.g.0.0.0.0:8899or[::]:8899), the RpcClient will receive an invalid endpoint likehttp://0.0.0.0:8899, causing transaction sends to fail. The default configuration uses127.0.0.1:8899, which is safe.To make this fully robust for wildcard configurations, either add normalization to
BindAddress::http()to convert unspecified IPs to loopback, or document thatlistenmust be a reachable address (not a wildcard bind).

Learning: In magicblock-processor, the TransactionScheduler runs in a single, dedicated thread and will always remain single-threaded. The `next_transaction_id()` function in scheduler/locks.rs uses `unsafe static mut` which is safe given this architectural guarantee.

Timestamp: 2025-11-20T17:25:23.444Z
Learning: In the magicblock-validator codebase, task IDs (task_id) are i64 values that can be negative. The task scheduler is designed to handle any i64 value including negative task IDs. Task IDs are randomly generated using rand::random() which produces values across the full i64 range. No validation is needed to restrict task IDs to positive values.

Learning: In magicblock-processor's TransactionScheduler (scheduler/mod.rs line 59), the executor count is clamped to MAX_SVM_EXECUTORS (63) at initialization time, and executor IDs are assigned sequentially from 0 to count-1. This architectural guarantee ensures that executor IDs used in the bitmask-based AccountLock (scheduler/locks.rs) will always be within valid bounds for bit shifting operations, making runtime bounds checks unnecessary.

22-22: Appropriate addition to.gitignorefor test artifacts.The new entry
magicblock-test-storage/correctly ignores test-generated storage artifacts and aligns with the removal of the task-scheduler integration test suite. The placement within the Ledger section is consistent with related test ledger ignores.

This has been removed because the unit tests used test-kit, which does not provide the RPC the service depends on. Integration tests for the service are still functional

106-149: Hotfix fully disables frequency-based commits; consider making this explicitThe guard
Some(commit_frequency_ms) if commit_frequency_ms > 0 && falsemakes the scheduling branch unreachable, socommit_frequency_msis effectively ignored and onlymodify_ixis ever sent. That matches the “do not schedule frequency commits” hotfix comment but is quite implicit.Consider either:
- Gating the scheduling branch behind a clearly named constant/config flag (e.g.
ENABLE_FREQUENCY_COMMITS: bool) instead of&& false, and/or- Emitting at least a debug/warn log when
commit_frequency_msisSome(>0)to make it obvious that periodic commits are currently disabled.This keeps the hotfix behavior while making it more self-documenting and easier to flip later.

14-90: SubscribeProgram handling mirrors Subscribe; consider adding targeted testsThe new
SubscribeProgram(Pubkey, usize)variant is wired consistently:
op_name,required_confirmations, and the zero-confirmations validation treat it identically toSubscribe.- Dispatch correctly calls
client.subscribe_program(program_id).await.Functionally this looks sound. To guard regressions, it would be useful to add a couple of small unit tests (similar to the existing Subscribe tests) that exercise:
- A successful
SubscribeProgramacross one or more clients, and- The zero-confirmations error path for
SubscribeProgram.That would ensure the new variant stays behaviorally aligned with
Subscribeas the API evolves.magicblock-task-scheduler/src/service.rs (1)
194-223: Note: Transaction execution result is not verified.The TODO comment at lines 197-201 correctly identifies that the transaction outcome isn't verified after
send_transaction. Since the PR objective is to ensure accounts get cloned via Chainlink, consider whether transaction failures should be handled more proactively (e.g., by polling for confirmation or usingsend_and_confirm_transaction).Would you like me to suggest an implementation using
send_and_confirm_transactionor a separate confirmation polling task?

Learning: In test-integration/test-chainlink/tests/ix_remote_account_provider.rs and similar test files, the `_fwd_rx` receiver returned by `init_remote_account_provider()` is intentionally kept alive (but unused) to prevent "receiver dropped" errors on the sender side. The pattern `let (remote_account_provider, _fwd_rx) = init_remote_account_provider().await;` should NOT be changed to `let (remote_account_provider, _) = ...` because dropping the receiver would cause send() operations to fail.

Learning: In magicblock-chainlink/src/submux/mod.rs, the subscribe_program method intentionally adds program_id to program_subs before attempting the subscription. This ensures that even if the initial subscription fails or only partially succeeds across clients, the reconnection logic will retry the subscription. This is a deliberate design pattern for resilience in the multi-client architecture and should not be "fixed" to remove entries on failure.

Downstream code should not attempt to inspect an unsubscribe result and can optionally wrap it in a timeout to guard against hangs.

Learning: In magicblock-chainlink/src/remote_account_provider/mod.rs, the `Endpoint::separate_pubsub_url_and_api_key()` method uses `split_once("?api-key=")` because the api-key parameter is always the only query parameter right after `?`.

Learning: In the magicblock-validator codebase, task IDs (task_id) are i64 values that can be negative. The task scheduler is designed to handle any i64 value including negative task IDs. Task IDs are randomly generated using rand::random() which produces values across the full i64 range. No validation is needed to restrict task IDs to positive values.

Learning: In magicblock-processor's TransactionScheduler (scheduler/mod.rs line 59), the executor count is clamped to MAX_SVM_EXECUTORS (63) at initialization time, and executor IDs are assigned sequentially from 0 to count-1. This architectural guarantee ensures that executor IDs used in the bitmask-based AccountLock (scheduler/locks.rs) will always be within valid bounds for bit shifting operations, making runtime bounds checks unnecessary.

Maintaining slack capacity is beneficial for performance by avoiding frequent reallocations during high transaction throughput.

config.program_subs()intoSubMuxClientat startup and logging the list is good, and callingsubscribe_programhere respects the SubMux “remember program_subs and resubscribe on reconnect” pattern.Because of the
?, if anysubscribe_programcall fails hard (i.e., doesn’t reach the required confirmations across all clients),try_new_from_urlsreturns an error and theRemoteAccountProviderisn’t constructed. That’s a reasonable “fail-fast” choice if configured program subscriptions are mandatory, but it does mean transient issues on those subscriptions will prevent chainlink from starting.Please double-check that this strict behavior is intended; if program subscriptions are meant to be best-effort, you might instead want to log failures and proceed, relying on the reconnection logic to heal later.
Based on learnings, this keeps SubMux’s program_subs-based reconnection behavior intact.

79-88: LGTM!The default implementation correctly initializes
program_subswithdlp::id()(the delegation program), which is a sensible default for the subscription backup mechanism.magicblock-chainlink/src/remote_account_provider/chain_pubsub_client.rs (6)
17-20: LGTM!Imports correctly added for the new program subscription types:
RpcProgramAccountsConfigandRpcKeyedAccount.
39-42: LGTM!The
ProgramSubscribeResulttype alias mirrors the existingSubscribeResultpattern, maintaining consistency in the codebase.
154-157: LGTM!The
subscribe_programmethod is correctly added to theChainPubsubClienttrait with a consistent signature pattern.
254-270: LGTM!The
subscribe_programimplementation correctly:
- Uses the actor message pattern consistent with
subscribe- Sends
ChainPubsubActorMessage::ProgramSubscribe- Includes appropriate error logging with
inspect_err
455-469: LGTM!The mock implementation correctly:
- Checks connection state before allowing subscription
- Returns appropriate error when disconnected
- Documents that program subscriptions don't track individual accounts in the mock
89-110: Unsafe lifetime extension consistently applied across subscription methods.Both
account_subscribe(lines 80–85) andprogram_subscribe(lines 103–108) use identical unsafe transmute patterns to extend stream lifetimes to'static. The safety comments are consistent and correctly document the reasoning: the stream depends on the client instance, which is only dropped when the connection terminates, at which point the stream is discarded regardless.magicblock-chainlink/src/chainlink/mod.rs (4)
13-13: LGTM!Import addition for
ChainLinkConfigis correctly placed and aligns with the config-based parameter refactoring.
65-68: LGTM!The
remove_confined_accountsfield is well-documented and correctly typed. The blank line before the doc comment improves readability.
73-99: LGTM - Config-based initialization is cleaner.The signature change from individual parameters to
&ChainLinkConfigimproves API ergonomics and extensibility. Field initialization from config is straightforward.
102-151: LGTM!The
try_new_from_endpointssignature update correctly propagateschainlink_configto the innertry_newcall, maintaining consistency across the initialization paths.magicblock-chainlink/src/submux/mod.rs (5)
140-142: LGTM!The
program_subsfield correctly usesArc<Mutex<HashSet<Pubkey>>>for thread-safe sharing across reconnection tasks, consistent with the existingsubscriptionspattern.
205-228: LGTM!Initialization and propagation of
program_substhrough the reconnector spawn path is correctly wired. The clone before passing to spawn ensures each task has its own Arc reference.
240-268: LGTM!The
spawn_reconnectorsfunction correctly clonesprogram_subsfor each client's reconnection task, ensuring the shared state is accessible during reconnection attempts.
641-662: LGTM - Resilient subscription pattern correctly implemented.The
subscribe_programmethod correctly adds toprogram_subsbefore attempting the subscription, ensuring reconnection logic will retry failed subscriptions. This aligns with the established pattern per project learnings.The
warn!log level for existing subscriptions is appropriate as it indicates a potential logic issue in the caller without being an error.
330-343: Consider whether program resubscription failure should abort the entire reconnect.Currently, if any single program subscription fails during reconnect, the entire reconnect is considered failed and will be retried. This is conservative but may cause unnecessary retry loops if a single program consistently fails to subscribe while others succeed.
Consider whether partial success (logging the failure but continuing with other programs) would be more resilient, similar to how account subscription failures are handled in some systems.

522-653: LGTM - Program subscription implementation is well-structured.The
add_program_subfunction correctly:
- Checks for existing subscriptions to avoid duplicates
- Inserts cancellation token before async subscription to prevent race conditions
- Filters updates to only forward accounts that are also directly subscribed (lines 609)
- Handles EOF by signaling connection issues
- Cleans up with timeout on unsubscribe
The filtering at line 609 implements the documented behavior from the enum variant comment.
712-732: Good refactoring - DRY improvement for subscription draining.The
drain_subscriptionshelper function reduces code duplication and makes the abort logic cleaner. The function correctly:
- Takes ownership of all subscriptions via
std::mem::take- Cancels each subscription's token
- Logs the count of cancelled subscriptions
604-620: Potential performance concern with lock acquisition in hot path.The
subs.lock()call inside the update loop (line 609) acquires a mutex lock for every program account update. If the program has many accounts with frequent updates, this could become a bottleneck.Consider caching the subscribed accounts set periodically or using a read-optimized concurrent data structure if performance becomes an issue.

33-50: RpcClient injection intoTaskSchedulerServicelooks good; consider refreshing surrounding commentsThe new
rpc_client: RpcClientfield and corresponding constructor parameter cleanly decouple the scheduler from the old executor and align with the “send crank txs via RPC” objective. Struct initialization innewis consistent and there are no ownership/lifetime issues.Two small follow‑ups for clarity:
- Line 38:
scheduled_tasks’s doc string still mentions “transaction executor”, which is no longer accurate with the new wiring.- Lines 57‑60: the SAFETY comment still refers to
TransactionSchedulerHandle; updating it to mentionRpcClient(and dropping obsolete types) will keep the unsafe justification in sync with the actual fields.Also applies to: 64-71, 87-90

103-105: Clarify the semantics of the Noop(u64) payload
Noop(u64)is now part of the public instruction API, but the doc comment doesn’t explain what theu64represents or whether it’s ignored by the processor (currently matched asNoop(_)). Expanding the docs will help callers understand if this is simply a nonce/unique identifier or reserved for future use.You could apply something along these lines:
- /// Noop instruction - Noop(u64), + /// Noop instruction (no operation). + /// + /// The `u64` payload is not interpreted by the program and can be used + /// by callers as a nonce/unique identifier (e.g. for tests or tx hashing). + /// It is currently ignored during execution. + Noop(u64),

Learning: In magicblock-task-scheduler, task parameter validation (including ensuring iterations > 0 and enforcing minimum execution intervals) is performed in the Magic program (on-chain) before ScheduleTaskRequest instances reach the scheduler service. The From<&ScheduleTaskRequest> conversion in db.rs does not need additional validation because inputs are already validated at the program level.

Learning: In test-integration/test-chainlink/tests/ix_remote_account_provider.rs and similar test files, the `_fwd_rx` receiver returned by `init_remote_account_provider()` is intentionally kept alive (but unused) to prevent "receiver dropped" errors on the sender side. The pattern `let (remote_account_provider, _fwd_rx) = init_remote_account_provider().await;` should NOT be changed to `let (remote_account_provider, _) = ...` because dropping the receiver would cause send() operations to fail.

Learning: In magicblock-processor's TransactionScheduler (scheduler/mod.rs line 59), the executor count is clamped to MAX_SVM_EXECUTORS (63) at initialization time, and executor IDs are assigned sequentially from 0 to count-1. This architectural guarantee ensures that executor IDs used in the bitmask-based AccountLock (scheduler/locks.rs) will always be within valid bounds for bit shifting operations, making runtime bounds checks unnecessary.

30-37: The addition oflibclang-devis necessary and correctly placed.RocksDB is a workspace dependency that uses
rocksdb-sysfor C bindings, which requireslibclang-devheaders to compile successfully. The Cargo.toml explicitly references rocksdb-sys and includes a comment about build compatibility. This dependency addition aligns with the recent RocksDB patch (0.23.0) and is not optional—it's required for the build to succeed on Linux.magicblock-ledger/Cargo.toml (1)
33-33: No issues found with rocksdb workspace dependency reference.The rocksdb dependency in magicblock-ledger correctly uses
workspace = true. The root Cargo.toml intentionally overrides the workspace.dependencies.rocksdb with a git source (parent commit d4e9e16 of rocksdb 0.23.0) to resolve Solana version conflicts. This override is documented and marked for removal once Solana is upgraded to 2.3. The inline features declaration in magicblock-ledger matches the workspace configuration.Cargo.toml (2)
190-193: Verify solana-svm revision 3e9456ec4 for compatibility and stability.The solana-svm revision has been updated to 3e9456ec4, which is currently associated with PR 10 in the magicblock-svm repository. Confirm that this commit is stable and does not introduce breaking changes to the magicblock-svm fork or dependent crates in the workspace.
195-212: Rocksdb version mismatch is intentional but pending resolution.The workspace declares rocksdb
0.22.0but patches it to git revd4e9e16(a parent commit of0.23.0) specifically to avoid linker conflicts with solana dependencies. Onlymagicblock-ledgerdirectly uses rocksdb in the workspace, and it correctly inherits the lz4 feature from the workspace dependency.The configuration is documented and intentional. However, the TODO to remove this patch upon solana 2.3 upgrade should reference a tracked issue or sprint plan for visibility and accountability.

242-252: ClarifyForkGraph::relationshipdirection and forkless assumptionThe linear ordering (
a < b→Ancestor,a > b→Descendant,a == b→Equal) looks sensible for a forkless chain, but correctness depends on howForkGraph::relationship(a, b)defines the relation (i.e., “relation ofatob” vs the inverse). Please double‑check this againstsolana_program_runtime::loaded_programs::ForkGraph/BlockRelationdocs and confirm that:
- the direction (
avsb) matches Solana’s expectation, and- assuming a strictly linear, forkless slot sequence is acceptable for all current uses of
SimpleForkGraph(e.g., no future support for reorgs/forks relying on this).programs/magicblock/src/magicblock_processor.rs (1)
35-81: Noop arm correctly wired as a pure no-opThe new
Noop(_) => Ok(())arm cleanly handles the added enum variant without touching accounts or altering existing flows. This is a safe, backwards-compatible extension of the instruction dispatcher.programs/magicblock/src/schedule_task/process_schedule_task.rs (1)
155-164: Tests now use shared Noop helper with unchanged semanticsSwitching
create_simple_ixtoInstructionUtils::noop_instruction(0)preserves the “no accounts, no signers” behavior of the simple test instruction while centralizing Noop construction. This keeps the schedule‑task tests aligned with the on‑chain validation invariants (interval, iterations, non‑empty instructions) that the scheduler service relies on.Based on learnings, this keeps validation where it belongs in the Magic program.

282-291: Noop helper is correctly scoped and implemented

12-12: Use ephem blockhash helper instead of NOOP helperImporting

InstructionUtils::noop_instruction(self.tx_counter.fetch_add(1, Ordering::Relaxed))to prepend a unique noop instruction achieves per‑tx uniqueness without affecting task instructions. Given the scheduler is confined to a single Tokio task (per the SAFETY comment),AtomicU64with relaxed ordering is sufficient here.

279-297: Consider passing a higher‑level config handle instead of a raw RPC URL String
TaskSchedulerService::newnow takesconfig.listen.http()as aString, which leaks knowledge of how the validator constructs its local RPC endpoint into the scheduler API. Long‑term, you might want to pass eitherconfig.listen(BindAddress) or a smallTaskSchedulerRpcConfigstruct and let the scheduler decide how to materialize the client URL, to reduce coupling between layers.magicblock-task-scheduler/src/service.rs (1)

TransactionSchedulerHandle, but the struct now holds anRpcClientinstead. For future maintainers reviewing the unsafeSend/Syncimpls, please update the comment to list the current fields (includingRpcClient) so the justification matches the actual struct layout.

301-329: Use theSignaturereturned byRpcClient::send_transactionand make RPC error mapping explicit
process_transactionderives the signature fromtx.signatures[0]and ignores theSignaturereturned bysend_transaction, while relying onmap_err(Box::new)?plus the#[from] Box<...::Error>onTaskSchedulerError::Rpc. This duplicates the source of truth for the signature and hides the error mapping behind an extra boxing step.You can simplify and make this clearer by using the returned signature and constructing the error variant directly:
- let sig = tx.signatures[0]; - self.rpc_client - .send_transaction(&tx) - .await - .map_err(Box::new)?; - Ok(sig) + self.rpc_client + .send_transaction(&tx) + .await + .map_err(|e| TaskSchedulerError::Rpc(Box::new(e)))This uses the actual RPC response signature and documents the error conversion in one place.

Timestamp: 2025-11-12T09:46:27.553Z
Learning: In magicblock-task-scheduler, task parameter validation (including ensuring iterations > 0 and enforcing minimum execution intervals) is performed in the Magic program (on-chain) before ScheduleTaskRequest instances reach the scheduler service. The From<&ScheduleTaskRequest> conversion in db.rs does not need additional validation because inputs are already validated at the program level.

Learning: In the magicblock-validator codebase, magicblock-api/Cargo.toml intentionally uses borsh = "1.5.3" (instead of the workspace version 0.10.4) because it needs to deserialize types from the magic-domain-program external dependency, which requires borsh 1.5.x compatibility. This is an intentional exception for interoperability with the magic domain program.

68-85: Addingcreated_at/updated_atwithout migration will break existing scheduler databasesThe
taskstable now includescreated_atandupdated_atasINTEGER NOT NULL, andinsert_taskunconditionally inserts into these columns. However,CREATE TABLE IF NOT EXISTSdoes not alter an existing table, so any pre-existingtask_scheduler.sqlitecreated before this change will not have those columns. On upgrade,INSERT OR REPLACE INTO tasks (...)will fail with "no such column: created_at/updated_at", breaking task scheduling (and possibly validator startup).You'll need either:
- a schema migration path (e.g., detect missing columns and
ALTER TABLEto add them with sensible defaults), or- a deliberate reset strategy (e.g., force
config.task_scheduler.reset = truefor this release and clearly document that tasks DB will be wiped).Right now this is a silent migration hazard.

194-223: Consider retry logic for transient RPC failures.The current implementation removes and logs failed tasks (lines 270-271), which is reasonable. However, for improved resilience, consider distinguishing between transient network errors (which could be retried) versus permanent failures (invalid transaction). This could be implemented by:
- Inspecting the error type from
send_transaction- Implementing a bounded retry with backoff for retriable errors
- Only marking the task as failed after retry exhaustion
This is optional and depends on the reliability requirements for scheduled tasks.
57-62: Update the safety comment to reflect the actual struct fields and verify necessity of unsafe impls.The safety comment lists
TransactionSchedulerHandle(line 58) which is not a field in the struct, and omitsRpcClientwhich is. Update the comment to accurately list:SchedulerDatabase, RpcClient, ScheduledTasksRx, LatestBlock, DelayQueue, HashMap, AtomicU64, CancellationToken. If all these fields are confirmed to beSend+Sync, consider whether the unsafe impls can be removed and let the compiler auto-derive these traits, or document the specific reason they remain necessary.

Timestamp: 2025-11-12T09:46:27.553Z
Learning: In magicblock-task-scheduler, task parameter validation (including ensuring iterations > 0 and enforcing minimum execution intervals) is performed in the Magic program (on-chain) before ScheduleTaskRequest instances reach the scheduler service. The From<&ScheduleTaskRequest> conversion in db.rs does not need additional validation because inputs are already validated at the program level.

Learning: In magicblock-processor, the TransactionScheduler runs in a single, dedicated thread and will always remain single-threaded. The `next_transaction_id()` function in scheduler/locks.rs uses `unsafe static mut` which is safe given this architectural guarantee.

Learning: The PhotonIndexer used for compressed account fetches (get_compressed_account) has built‑in retry logic (defaults to ~10 attempts), so tests should not add separate retry loops around compressed fetches unless there’s a specific need.

Learning: In magicblock-chainlink/src/remote_account_provider/chain_pubsub_client.rs, the unsubscribe closure returned by PubSubConnection::account_subscribe(...) resolves to () (unit), not a Result. Downstream code should not attempt to inspect an unsubscribe result and can optionally wrap it in a timeout to guard against hangs.

Timestamp: 2025-11-19T09:34:37.917Z
Learning: In test-integration/test-chainlink/tests/ix_remote_account_provider.rs and similar test files, the `_fwd_rx` receiver returned by `init_remote_account_provider()` is intentionally kept alive (but unused) to prevent "receiver dropped" errors on the sender side. The pattern `let (remote_account_provider, _fwd_rx) = init_remote_account_provider().await;` should NOT be changed to `let (remote_account_provider, _) = ...` because dropping the receiver would cause send() operations to fail.

File: magicblock-chainlink/src/submux/mod.rs:652-654
Timestamp: 2025-12-01T16:02:05.367Z
Learning: In magicblock-chainlink/src/submux/mod.rs, the subscribe_program method intentionally adds program_id to program_subs before attempting the subscription. This ensures that even if the initial subscription fails or only partially succeeds across clients, the reconnection logic will retry the subscription. This is a deliberate design pattern for resilience in the multi-client architecture and should not be "fixed" to remove entries on failure.

Learning: In magicblock-committor-service's SingleStageExecutor and TwoStageExecutor (single_stage_executor.rs and two_stage_executor.rs), the fields transaction_strategy, junk, and patched_errors are intentionally public because these executors are designed to be used independently outside of the IntentExecutor scope, and callers need access to these execution reports for cleanup and error handling.

File: magicblock-processor/src/scheduler/locks.rs:64-102
Timestamp: 2025-11-13T09:38:43.804Z
Learning: In magicblock-processor's TransactionScheduler (scheduler/mod.rs line 59), the executor count is clamped to MAX_SVM_EXECUTORS (63) at initialization time, and executor IDs are assigned sequentially from 0 to count-1. This architectural guarantee ensures that executor IDs used in the bitmask-based AccountLock (scheduler/locks.rs) will always be within valid bounds for bit shifting operations, making runtime bounds checks unnecessary.

Timestamp: 2025-11-20T17:25:23.444Z
Learning: In the magicblock-validator codebase, task IDs (task_id) are i64 values that can be negative. The task scheduler is designed to handle any i64 value including negative task IDs. Task IDs are randomly generated using rand::random() which produces values across the full i64 range. No validation is needed to restrict task IDs to positive values.
