A network experiencing peer churn could produce continuous false failures, + masking real issues. `BroadcastAndProcessBlock` now returns `nil` on + consensus-not-reached; the round ends cleanly and the next round begins normally. + +- **Local block processing responsibility separated from broadcast** + (`messaging/broadcast.go`, `Sequencer/consensus_statemachine.go`). + `BroadcastBlockToEveryNodeWithExtraData` contained `ProcessBlockLocally` call sites + that did not belong in the broadcast layer. Removed; local processing is now the + exclusive responsibility of `BroadcastAndProcessBlock` in the consensus state machine. + +- **Pubsub unsubscribe failure logged at wrong level** + (`Pubsub/Subscription/Subscription.go`). + Topic unsubscribe failure downgraded from `Error` to `Warn`. + +### Changed + +- **Trace context propagation through consensus pipeline** + (`Sequencer/consensus_statemachine.go`, `Sequencer/Consensus.go`). + `warmup`, `BroadcastAndProcessBlock`, and `CleanupSubscriptions` now accept and + propagate `context.Context`. The active OTEL span is now correctly carried through + the full consensus execution path, enabling end-to-end distributed tracing of each + consensus round. + +- **Structured logging across consensus internals** + (`Sequencer/consensus_statemachine.go`, `Sequencer/Consensus.go`). + All unstructured `log.Printf` and `fmt.Printf` calls replaced with + `logger().NamedLogger` structured calls carrying span context and ion fields. + Block number, block hash, and consensus outcome are now indexed on every relevant + log entry, making per-block trace correlation possible in log aggregation. + +- **Error wrapping** (`Sequencer/consensus_statemachine.go`, `messaging/broadcast.go`). + `fmt.Errorf("...: %v", err)` → `fmt.Errorf("...: %w", err)` for proper + `errors.Is` / `errors.As` unwrapping by callers. + +- **Hot-path per-vote logging removed** (`Sequencer/Triggers/Maps/vote_results.go`). + `StoreVoteResult` and `ClearVoteResults` emitted `log.Printf` on every call. + Removed. + +### Added + +- **FastSync V2 engine** (`FastsyncV2/fastsyncv2.go` — new, 851 lines). + Replaces the legacy sync engine to solve node data divergence that was blocking + consensus: nodes with inconsistent account state could not agree on block validity. + V2 introduces a structured multi-phase protocol over libp2p — + PriorSync (Merkle root comparison) → HeaderSync (skeleton headers) → + DataSync (full transactions + ZK proofs) → Reconciliation (account balances) → + PoTS (catch-up on blocks produced during sync) — that brings any node to full, + verified parity before it participates in consensus. The Reconciliation phase + resolves account state divergence independently of block sync. + CLI aliases `fastsync`, `fastsyncv2`, and `firstsync` all dispatch to the V2 engine. + Serve and pull are decoupled: `fastsync.enabled` registers protocol handlers; + `fastsync.enable_pulling` gates any write to the local database, allowing sequencers + to serve data without accepting remote state. + +- **`accountsync` CLI command and gRPC RPC.** + Calls `FastsyncV2.AccountSyncOnly`, syncing only missing accounts from a peer + without touching block data. Backed by `CLI.handleAccountSync`, + `CLI_GRPC.HandleAccountSync`, and `GRPC_Server.AccountSync`. + +- **Startup sync** (`FastsyncV2.HandleStartupSync`). + When `fastsync.pull_on_startup: true`, the node automatically pulls blocks missed + while offline, starting from the local chain tip. Registered as goroutine-orchestrator + thread `thread:startup:sync` (`config/GRO/constants.go`). + +- **Redis Stream account sync worker** (`DB_OPs/Nodeinfo/account_sync_redis.go`, + `account_sync_worker.go`). + Account writes are enqueued via `XADD` and consumed by a background worker + (`XREADGROUP` / `XACK`), decoupling callers from ImmuDB's ~15 s commit latency. + `enqueueRecordsChunked` splits payloads at `maxRecordsPerMessage` to prevent Redis + bulk-string size violations. Node boots without Redis (async 30 s retry loop). + +- **ImmuDB block adapters for V2** (`DB_OPs/Nodeinfo/`). + Seven new files providing isolated ImmuDB read/write layers for the V2 engine: + `immudb_adapter.go`, `immudb_auth.go`, `immudb_block_iterator.go`, + `immudb_blockheader_iterator.go`, `immudb_block_nonheaders.go`, + `immudb_data_writer.go`, `immudb_headers_writer.go`. + +- **`AccountSnapshot` struct** (`messaging/BlockProcessing/Processing.go`). + Captures `{Balance, TxNonce, TxCountSent, UpdatedAt}` for every affected account + before a block is applied. Used by `rollbackState` to restore all four fields if any + transaction in the block fails. + +- **`FastSyncSettings`, `RedisSettings`, `DatabaseSettings` config structs** + (`config/settings/config.go`). + New `fastsync:` and `database.redis:` config sections. Full Viper defaults and + env-var bindings in `defaults.go` and `loader.go`. `jmdn_default.yaml` updated to + reflect all new fields with correct key names. + +- **OTEL custom exporter headers** (`config/settings/config.go`, + `logging/otelsetup/setup.go`). + `Headers map[string]string` field on `LogOTELSettings`. Setup function uses + field-by-field assignment so `Headers` propagates correctly. + +- **`FastSyncV2` and `AccountSync` gRPC RPCs** (`CLI/proto/Connection.proto`). + Two new methods on `CLIService`. Existing `FastSync` and `FirstSync` RPCs preserved. + `convertDBState` in `GRPC_Server.go` nil-guards before dereferencing. + +- **`GetZKBlockByNumberFast`** (`DB_OPs/immuclient.go`). + Proof-free block retrieval via plain `Get` (5–10× faster than `GetZKBlockByNumber`), + for sync/reconciliation paths that do not require tamper-proof reads. + +- **`PullAllowed` flag on `CommandHandler`** (`CLI/CLI.go`). + Set from `fastsync.enable_pulling` at startup. All pull-capable CLI and gRPC + handlers check it and return an error if false. + +- **Security service Viper defaults** (`config/settings/loader.go`). + All predefined `security.services.*` entries registered with `SetDefault`, enabling + full env-var override of nested service policies. + +- **`account_sync_enqueue_test.go`.** + Unit tests for bounded-enqueue chunking logic using a recording mock streamer; + no live Redis or ImmuDB required. + +- **`jmdn.yaml` added to `.gitignore`.** + Production node config is now excluded from version control by default, preventing + accidental credential commits. Also added: `internal/WAL/.tmp/*`, `.claude/*`, + `.code-review-graph/*`, `.cursor/*`. + +### Fixed + +- **Same-block nonce replay — two-layer defence.** + + *Layer 1 (admission, `Security/Security.go`):* Nonce validation now reads + `account.TxNonce` from `SecurityCache` instead of querying ImmuDB. + `UpdateTxNonce` advances the in-memory value immediately on each accepted + transaction, so a second tx from the same sender in the same block is rejected at + the gate. + + *Layer 2 (execution, `messaging/BlockProcessing/Processing.go`):* + `deductFromSender` performs a second nonce check against the DB record + (`tx.Nonce < didDoc.TxNonce`) as defense-in-depth. It also writes + `TxNonce = tx.Nonce + 1` and `TxCountSent++` to ImmuDB via `DB_OPs.UpdateAccount`, + making nonce state durable beyond cache lifetime. + +- **`PutNonceofAccount` ART key collision** (`DB_OPs/account_immuclient.go`). + Function packed `time.Now().UnixNano()` and an atomic counter into the ART key; + under concurrency the counter collided and the timestamp was approaching overflow. + Removed; `CreateAccount` now calls `GenerateARTNonce()`. Corresponding test + `Test_Account_Nonce_Generation` removed. + +- **`defer ctx.Done()` context leak in `CLI/client.go` `FastSync`.** + `defer ctx.Done()` is a no-op on a `context.Background()` (returns a nil channel), + but signals incorrect intent and masks real context lifecycle. Removed. + +- **Block processing rollback left dirty nonce state** + (`messaging/BlockProcessing/Processing.go`). + `rollbackBalances` restored only `Balance`. Replaced by `rollbackState`, which + overwrites `Balance`, `TxNonce`, `TxCountSent`, and `UpdatedAt` from the pre-block + snapshot. Per-tx nested rollback inside `processTransaction` removed; `rollbackState` + at block level is the sole rollback authority. + +- **`BatchRestoreAccounts` duplicate-key error** (`DB_OPs/account_immuclient.go`). + Reconciliation pages can deliver the same address multiple times. Deduplication + (LWW by `UpdatedAt`) now applied before `ExecAll`. + +- **`BatchRestoreAccounts` DID and metadata loss** + (`DB_OPs/account_immuclient.go`, `DB_OPs/Nodeinfo/account_sync_worker.go`). + Field-merges `DIDAddress`, `CreatedAt`, `AccountType`, and `Metadata` from the + existing DB record before writing, preventing data loss for active accounts. + +- **`getKeysBatch` prefix scan returning wrong results** (`DB_OPs/immuclient.go`). + `Desc: true` → `Desc: false`. Descending scans with no matching keys fall backward + past the prefix boundary and return unrelated entries. + +- **Pubsub topic close race** (`Pubsub/Subscription/SubscriptionManager.go`). + Both `Unsubscribe` and `Shutdown` called `managed.pubsubTopic.Close()` on a locally + cached reference, racing with concurrent re-subscribe. Both now call + `sm.gps.CloseTopic(topic)`. + +- **`HeadersWriter` prematurely advancing `latest_block` marker** + (`DB_OPs/Nodeinfo/immudb_headers_writer.go`). + HeaderSync writes skeleton blocks before transactions are available; the marker was + being updated, causing `StartupSync` and the explorer to consider the node fully + synced. Marker is now snapshotted before `WriteHeaders` and restored unconditionally + after. + +- **Merkle hash divergence on fast-synced nodes** + (`DB_OPs/Nodeinfo/immudb_block_nonheaders.go`, `immudb_data_writer.go`, + `immudb_headers_writer.go`). + `ChainID`, `AccessList`, and `LogsBloom` were not serialised in V2 protobufs. + All three fields now round-trip correctly. + +- **`CheckNonceAndGetLatest` uint64 underflow on fresh chains** (#22). + Inner loop `for i := currentBlock; i >= startBlock; i--` wrapped to `math.MaxUint64` + when `startBlock == 0`. Restructured as a top-decrement loop. + +- **P2P DID gossip discarded network ART Nonce** (`messaging/DIDPropagation.go`). + `CreateAccount` assigned a fresh local `Nonce`, diverging from the sender's ART + index. Changed to `StorePropagatedAccount`, which writes the exact received `Nonce`. + +- **`immudb_account_manager` key-not-found** (`DB_OPs/Nodeinfo/immudb_account_manager.go`). + `GetAccountByAddress` returns zero balance on a missing key rather than an error. + +- **`GetLatestBlockNumber` non-deterministic** (`DB_OPs/immuclient.go`). + Retry-with-reconciliation wrapper removed; single direct read. + +- **`eth_getBalance` error on unknown address** (`gETH/Facade/Service/Service.go`). + On key-not-found: attempts `CreateAccountandPropagateDID` (error logged, not + returned); always returns `big.NewInt(0)`. + +- **Go 1.25 deprecation warnings** (`AVC/BLS/bls-sign/bls-sgin.go`, `seednode/seednode.go`). + `ioutil.ReadFile/WriteFile` → `os.ReadFile/WriteFile`; `reflect.Ptr` → `reflect.Pointer`. + +### Changed + +- **Account struct** (`DB_OPs/account_immuclient.go`). + + | Field | Before | After | Purpose | + |---|---|---|---| + | `Nonce` (formerly `StateID`) | `time.Now()`-based ART key | deterministic (`GenerateARTNonce`) | Fastsync ART leaf index | + | `TxNonce` | — | new `uint64` | Ethereum transaction nonce | + | `TxCountSent` | — | new `uint64` | analytical send counter | + +- **`UpdateAccountBalance` signature** (`DB_OPs/account_immuclient.go`). + Added `blockTimestamp int64`; `UpdatedAt` is now deterministic across nodes. + +- **`SecurityCache` method renames** (`Security/security_cache.go`). + `UpdateNonce` → `UpdateTxNonce`; `GetNonce` → `GetTxNonce`. + +- **`firstsync` command mode argument removed** (`main.go`, `CLI/CLI.go`). + `jmdn -cmd firstsync ` no longer accepts a mode argument. + All three aliases (`fastsync`, `fastsyncv2`, `firstsync`) now route to the V2 engine + with a single `` argument. Scripts using `firstsync … server` or + `firstsync … client` must be updated. + +- **Block transaction ordering** (`messaging/BlockProcessing/Processing.go`). + `sortTransactionsByNonce` removed. Sequencer-determined order is canonical. + +- **`processTransaction`, `deductFromSender`, `addToRecipient` signatures**. + All accept `blockTimestamp int64`. `deductFromSender` now takes + `*config.Transaction` (full tx) to support the execution-time nonce check. + +- **`BatchRestoreAccounts` signature** (`DB_OPs/account_immuclient.go`). + `context.Context` as first param; operations chunked at 1000 per ImmuDB tx; + single `GetAll` RPC replaces per-account `Get` calls. + +- **Vote submission logging** (`Vote/Trigger.go`). + `SubmitVote` now logs the target peer ID on each retry failure and on success, + replacing a generic error message. Aids diagnosis of vote propagation issues. + +- **`SyncStats.Error` checked in CLI output** (`main.go`). + `fastsync`, `fastsyncv2`, `firstsync`, and `accountsync` commands now print a + specific failure message and exit non-zero when `stats.Error` is non-empty, instead + of silently succeeding with zero stats. + +- **`TimeTaken` unit in CLI output** (`main.go`). + Sync duration now printed as seconds (`%ds`) instead of milliseconds (`%dms`), + matching the `SyncStats.TimeTaken` field unit. + +- **`DID.RegisterDID` timestamps** (`DID/DID.go`). `UnixNano()` instead of `Unix()`. + +- **HTTP server timeouts** (`explorer/api.go`). 10 s → 60 s. + +- **Legacy FastSync V1** (`fastsync/fastsync.go`). + `BatchRestoreAccounts` call updated to new signature (`context.Background()`). + +### Dependencies + +| Package | Change | +|---|---| +| `protoc` (build tool) | `v6.33.1` → `v7.34.1`; proto source path normalised | +| `JupiterMetaLabs/JMDN-FastSync` | Added — `v0.0.0-20260604113915-c1470ecc039d` | +| `redis/go-redis/v9` | Added — `v9.19.0` | +| `shirou/gopsutil` | Added — `v3.21.11+incompatible` (indirect) | +| `JupiterMetaLabs/JMDN_Merkletree` | `v0.0.0-20260205…` → `v0.0.0-20260413…` | +| `JupiterMetaLabs/ion` | `v0.3.5` → `v0.4.2` | +| `go.opentelemetry.io/otel` | `v1.40.0` → `v1.42.0` | +| `google.golang.org/grpc` | `v1.78.0` → `v1.79.3` | +| `grpc-ecosystem/grpc-gateway/v2` | `v2.27.3` → `v2.28.0` | +| `klauspost/compress` | `v1.18.2` → `v1.18.5` | + +--- + +## [1.1.1] -

Reliability & Stability Fixes - -### Protocol Stream Management -- **Application-Level Chunking (Phase 2)**: Re-implemented the HashMap exchange protocol to use chunked transfers (10,000 keys per chunk). This resolved `Stream Reset` and `EOF` errors caused by messages exceeding libp2p/gRPC limits (e.g., 120MB+ JSON messages). -- **Idle Timeout Mitigation**: Moved libp2p stream creation to *after* the local HashMap is computed in `HandleSync`. This prevents the server from timing out the stream while the client is still performing heavy I/O. -- **AVRO File Stability**: Fixed a "bad file descriptor" error in the AVRO writer by switching from `O_WRONLY` to `O_RDWR`, ensuring the writer can correctly manage headers and block positioning. -- **Resource Management**: Reduced batch sizes to 50 in `fastsync.go` to prevent `ResourceExhausted` gRPC errors during data restoration. - -### Connection & Timeout Tuning -- **Scan Scalability**: Increased the `GetAllKeys` timeout from 20 seconds to 10 minutes to accommodate large datasets. -- **Auto-Reconnect Logic**: Added retry and auto-reconnect logic to database scans to handle transient transport errors during long-running synchronization tasks. -- **Phase 3 Timeouts**: Increased client-side timeouts for AVRO file requests to prevent "double transfers" where a client would time out and re-request a file while the server was still sending the first one. - -## 2. Security & Verification Improvements - -### Content-Based Reconciliation (Merkle Root Fix) -- **Problem**: ImmuDB's Merkle Roots (`TxHash`) are history-dependent. Even if two nodes have identical data, their Merkle Roots mismatch if their transaction batching or history order differs. -- **Solution**: Implemented a **Content-Based Verification** system using HashMap Fingerprints (SHA256 of sorted keys). - - **Server**: Now computes a full-state fingerprint during the incremental scan in `computeSyncKeysIncremental`. - - **Client**: Re-computes a local fingerprint after data restoration and verifies it against the server's intended state fingerprint. - - **Result**: Reliable, mathematical proof that nodes are in sync, eliminating false-positive Merkle Root warnings. - -### Pre-Sync Optimization -- **Deduplication Check**: Added a pre-sync check that aborts synchronization if the Merkle Roots already match, saving significant bandwidth and CPU for nodes that are already synchronized. - -## 3. Maintenance & Developer Experience - -### Logging & Observability -- **Ion Logger Integration**: Fully integrated the `ion` logger into the `fastsync` package, replacing noisy `fmt.Println` calls with structured logging. -- **Progress Tracking**: Added progress logging to `writeMessage` and HashMap chunking to provide visibility into long-running data transfers. -- **Log Suppression**: Suppressed noisy "EOF" and "Stream Reset" errors in `handleStream` when they occur after a successful sync completion, treating them as expected closures. - -### Build & Code Quality -- **Syntax Cleanup**: Fixed duplicate package declarations and import order issues that were causing `make build` failures. -- **Error Handling**: Standardized error wrapping and panic recovery across all major sync phases. -

This means `defer nodeManager.Shutdown()` in `main` still does not execute on signal. - -**Status: 🟡 DEPENDENCY ON §1.1** — `Shutdown()` method likely correct; the call path is broken until signal handling is fixed. - ---- - -### 4.5 Yggdrasil listener — root context but `os.Exit` bypass -**Source:** `docs/SHUTDOWN_REVIEW.md §3` -**Original claim:** Receives root context, but cancel path never executes because of `os.Exit(1)`. - -**Verified:** Root context cancel IS now called (`cancel()` at `main.go:815`) before `shutdown.Shutdown()`. However since `os.Exit(0)` fires from the goroutine defer, the timeline is: cancel() → GRO shutdown → os.Exit(0). If Yggdrasil is registered with GRO, it would shut down. If it's not, `cancel()` alone may not be enough if its goroutine doesn't check `ctx.Done()`. - -**Status: 🟡 PARTIALLY IMPROVED** — requires GRO registration verification. - ---- - -## 5.

Count has grown (26 → 50+). - ---- - -### 5.2 Connection pool — `Close()` wired to shutdown? -**Source:** `docs/SHUTDOWN_REVIEW.md §2` -**Original claim:** `config/ConnectionPool.go:472-499` — `Close()` stops cleanup ticker and cancels clients, but `main` never calls it (defer skipped). - -**Verified:** Since defers in `main` still don't run on signal (§1.1), `defer DB_OPs.PutMainDBConnection(mainDBClient)` and related defers in `main` are still skipped.

Any failure or cancellation depends on implicit timeouts. - -### A.2 Implementation Steps - -#### Step A1 – Replace manual signal goroutine with `signal.NotifyContext` - -```518:575:main.go -func main() { - ctx, stop := signal.NotifyContext(context.Background(), syscall.SIGINT, syscall.SIGTERM) - defer stop() - - cfg := mustLoadConfig() - - bootCtx, cancelBoot := context.WithTimeout(ctx, cfg.Timeouts.Bootstrap) - defer cancelBoot() - - node, err := node.NewNodeWithContext(bootCtx, cfg.Node) - if err != nil { - log.Fatal().Err(err).Msg("failed to initialize node") - } - defer node.Host.Close() - - // ... - <-ctx.Done() - log.Info().Msg("shutdown signal received; waiting for subsystems to drain") -} -``` - -**Key changes:** -- Root context is bound to OS interrupts (`SIGINT`, `SIGTERM`); no manual `os.Exit`. -- Bootstrap work executes under `bootCtx` with a bounded timeout. -- The process blocks on `<-ctx.Done()` to allow deferred clean-up. - -#### Step A2 – Introduce `node.NewNodeWithContext` - -```114:205:node/node.go -// NewNodeWithContext creates and starts a libp2p node under the supplied context. -func NewNodeWithContext(ctx context.Context, opts config.NodeOptions) (*config.Node, error) { - privKey, peerID, err := loadOrCreatePrivateKey() - if err != nil { - return nil, fmt.Errorf("failed to load/create Peer ID: %w", err) - } - - host, err := libp2p.New( - libp2p.Identity(privKey), - libp2p.ListenAddrStrings(opts.ListenAddrs...), - libp2p.ResourceManager(newResourceManager(ctx)), - // ... - ) - if err != nil { - return nil, fmt.Errorf("failed to start libp2p: %w", err) - } - - go func() { - <-ctx.Done() - shutdownCtx, cancel := context.WithTimeout(context.Background(), opts.ShutdownTimeout) - defer cancel() - _ = host.Close() // release streams; rely on shutdownCtx for logging if needed - }() - - // remaining initialization unchanged -} -``` - -**Usage impacts:** -- Callers pass the root or phase-specific context. -- Resource manager (optional) can be derived from context for future cancellation hooks. - -#### Step A3 – Propagate context into bootstrap helpers - -```499:516:main.go -func initPubSub(ctx context.Context, n *config.Node) (*Pubsub.StructGossipPubSub, error) { - // ... - gossipPubSub, err := Pubsub.NewGossipPubSubWithContext(ctx, n.Host, pubSubProtocol) - // ... -} -``` - -Ensure `initFastSync`, `initSeedNode`, etc. accept context parameters and use `context.WithTimeout(ctx, cfg.Timeouts.FastSync)` where appropriate. - -#### Step A4 – CLI command propagation - -```24:46:CLI/client.go -func runClientCommand(ctx context.Context, args []string) error { - dialCtx, cancel := context.WithTimeout(ctx, timeouts.CLI.Dial) - defer cancel() - conn, err := grpc.DialContext(dialCtx, target, dialOptions...) - // ... -} -``` - -### A.3 Roll-out Checklist -- Update all call sites: `main.go`, `CLI/CLI.go`, tests, and any scripts invoking `node.NewNode()`. -- Validate that each `context.WithTimeout` derives from the propagated parent. -- Remove obsolete signal goroutines and `os.Exit` calls. - ---- - -## Phase B – Context-Aware Database Access - -### B.1 Baseline Observations -- `DB_OPs/immuclient.go` functions frequently start with `context.WithTimeout(context.Background(), X)` (example: `Create`, `GetByTxID`, `SyncZkBlocks`). Callers cannot cancel these operations. -- `config/ConnectionPool.go:createConnection` sets `BaseCtx: context.Background()` for pooled clients, making contextual configuration impossible. -- `Block/Server.go`, `gETH/Facade/Service.go`, and CLI command handlers call DB helpers without owning the context or timeout configuration. - -### B.2 Implementation Steps - -#### Step B1 – Centralize request timeout helper - -```320:379:config/ConnectionPool.go -type RequestTimeoutProvider interface { - RequestTimeout() time.Duration -} - -func (cp *ConnectionPool) WithRequestTimeout(parent context.Context) (context.Context, context.CancelFunc) { - timeout := cp.Config.ConnectionTimeout - if timeout <= 0 { - timeout = DefaultDBRequestTimeout // e.g., 8 * time.Second - } - return context.WithTimeout(parent, timeout) -} -``` - -- Store a pointer to the pool in `ImmuClient` (e.g., `Pool *ConnectionPool`) so DB helpers can reuse it. -- Update `ImmuClient.BaseCtx` to the parent context provided during login, not `context.Background()`. - -#### Step B2 – Make ImmuDB helper methods context-aware - -```226:273:DB_OPs/immuclient.go -func Create(ctx context.Context, pooled *config.PooledConnection, key string, value interface{}) error { - if ctx == nil { - return fmt.Errorf("nil context") - } - reqCtx, cancel := pooled.Client.Pool.WithRequestTimeout(ctx) - defer cancel() - - // existing validation unchanged - if pooled == nil { - var err error - pooled, err = GetMainDBConnectionandPutBack(reqCtx) - // ... - } - - if err := ensureMainDBSelected(pooled); err != nil { - return err - } - _, err := pooled.Client.DB.Set(reqCtx, &schema.SetRequest{ - KVs: []*schema.KeyValue{{ - Key: []byte(key), - Value: encoded, - }}, - }) - return err -} -``` - -- Repeat for getters (`Read`, `GetTx`, `Iterate` etc.) ensuring the first parameter is `ctx context.Context`. -- For functions that currently create internal contexts (e.g., `withRetry`), accept `ctx` as parameter and derive child contexts inside the retry loop: `attemptCtx, cancel := context.WithTimeout(ctx, backoff(i))`. - -#### Step B3 – Update call sites with real contexts - -Example in `Block/Server.go`: - -```357:430:Block/Server.go -func processZKBlock(w http.ResponseWriter, r *http.Request) { - ctx := r.Context() - storeCtx, cancel := context.WithTimeout(ctx, timeouts.API.ProcessZKBlock) - defer cancel() - - if err := DB_OPs.Create(storeCtx, nil, blockKey, blockData); err != nil { - // handle error - } -} -``` - -Example in `gETH/Facade/Service.go`: - -```104:138:gETH/Facade/Service/Service.go -func (s *Service) BlockByNumber(ctx context.Context, num *big.Int) (*types.Block, error) { - txCtx, cancel := s.dbPool.WithRequestTimeout(ctx) - defer cancel() - rec, err := s.dbClient.GetBlockByNumber(txCtx, num) - // ... -} -``` - -#### Step B4 – Tests & tooling -- Update `DB_OPs/Tests/*` to provide explicit contexts: `ctx, cancel := context.WithTimeout(context.Background(), 3*time.Second)`. -- Introduce helper `testContext(t *testing.T) (context.Context, context.CancelFunc)` to standardize tests. - -### B.3 Roll-out Checklist -- Run gofmt/goimports after signature changes. -- Ensure all `GetMainDBConnectionandPutBack` callers pass the inherited context. -- Monitor pool metrics (`config.DBPoolMetrics`) to confirm connection churn decreases during shutdown or cancellation scenarios. - ---- - -## Validation & Follow-up -- After applying Phase A & B, run integration tests exercising graceful shutdown (Ctrl+C) and DB-heavy workloads. -- Capture metrics before/after (CPU, open FDs, ImmuDB connection count) to validate improvements. -- Proceed with Phase C/D/E only after confirming baseline stability with these primary changes. - diff --git a/security-audit/prev/ENGINEERING_AUDIT.md b/security-audit/prev/ENGINEERING_AUDIT.md deleted file mode 100644 index 506b0774..00000000 --- a/security-audit/prev/ENGINEERING_AUDIT.md +++ /dev/null @@ -1,729 +0,0 @@ -# Engineering Audit Report -**Repository:** JMDT Decentralized Network (jmdn-3) -**Date:** 2025-01-28 -**Audit Type:** Internal Engineering Audit - ---- - -## 1.
