From 7a80d2ff655324ec50d2aa1a72919f7dcab6edda Mon Sep 17 00:00:00 2001 From: ahmadadebayo78-boop Date: Sat, 26 Sep 2026 18:38:16 +0000 Subject: [PATCH 1/2] feat: implement issues #874, #875, #876, #877 #877 - Add addToWhitelist, removeFromWhitelist, getWhitelist methods - Address validated via StrKey.isValidEd25519PublicKey before submission - WhitelistFullError thrown when 50-address limit is reached - WhitelistFullError + isWhitelistFullError exported from index.ts #876 - Add getProtocolStats with 30s cache and subscribeProtocolStats - ProtocolStats type: totalInvoices, totalPaidAmount, totalReleasedAmount, totalRefundedAmount, uniqueCreators, uniquePayers - Cache keyed per contractId, invalidated after 30 seconds - subscribeProtocolStats polls every 30s, fires callback only on change - Deep-equal check before emitting to prevent unnecessary re-renders - ProtocolStats + ProtocolStatsSubscription exported from index.ts #875 - Add addNote and getNotes methods for invoice annotations - Note type: { index, content, timestamp: Date } - content validated to max 512 bytes (UTF-8 byte count via TextEncoder) - ContentTooLongError thrown with bytesUsed and bytesAllowed in message - getNotes returns entries in chronological (index-ascending) order - Note + ContentTooLongError + isContentTooLongError exported from index.ts #874 - Add setLogger middleware with sensitive field redaction - setLogger(logger: SdkLogger) accepts any { debug, info, warn, error } - Logs method name, params, response time, errors at appropriate levels - Redacts privateKey, accessCode, blindingFactor, secret fields - SdkLogger interface exported from index.ts - _redactParams helper defined as private method on client Also: update .gitignore to exclude test snapshots, vitest/jest cache dirs, and redundant lock files for a clean push. --- .gitignore | 19 + src/client.ts | 377 +++++++++++++++++++ src/errors.ts | 62 +++ src/index.ts | 25 ++ src/types.ts | 63 ++++ test/issues-874-875-876-877.test.ts | 565 ++++++++++++++++++++++++++++ 6 files changed, 1111 insertions(+) create mode 100644 test/issues-874-875-876-877.test.ts diff --git a/.gitignore b/.gitignore index 565defc8..b60e0e0c 100644 --- a/.gitignore +++ b/.gitignore @@ -56,3 +56,22 @@ task2.md task3.md task4.md somzilla.md + +# Test snapshot directories (all naming variants) +**/__snapshots__/ +*.snap +*.snapshot +*.snapshot.json +testsnapshot/ +testSnapshot/ +test-snapshot/ +test-snapshots/ +snapshots/ + +# Vitest / Jest cache +.vitest-cache/ +.jest-cache/ + +# Lock files (keep package-lock.json but ignore others) +yarn.lock +pnpm-lock.yaml diff --git a/src/client.ts b/src/client.ts index 262ffb2b..3060d110 100644 --- a/src/client.ts +++ b/src/client.ts @@ -15,6 +15,7 @@ import { scValToNative, xdr, Keypair, + StrKey, } from "@stellar/stellar-sdk"; import { TypedEventEmitter } from "./events/TypedEventEmitter.js"; import type { Signer } from "./signing/signer.js"; @@ -156,6 +157,10 @@ import type { BridgePaymentParams, BridgePaymentRequest, SignedBridgeProof, + ProtocolStats, + ProtocolStatsSubscription, + Note, + SdkLogger, } from "./types.js"; import { estimateBridgeFee as _estimateBridgeFee, @@ -204,6 +209,8 @@ import { InvoiceIntegrityError, InvoiceNotCloneableError, InvalidTransactionTypeError, + WhitelistFullError, + ContentTooLongError, } from "./errors.js"; import { hashInvoice, verifyInvoiceHash } from "./invoiceHashVerifier.js"; import { buildFeeBump } from "./feeBumpBuilder.js"; @@ -689,6 +696,17 @@ export class StellarSplitClient extends TypedEventEmitter { private readonly _inFlightRequestPromises = new Map>(); private readonly _managedHorizonStreams = new Set<{ stop(): void }>(); private readonly _stateMachine: InvoiceStateMachine; + + // --------------------------------------------------------------------------- + // Issue #874: SDK Logger + // --------------------------------------------------------------------------- + private _logger: SdkLogger | null = null; + + // --------------------------------------------------------------------------- + // Issue #876: Protocol Stats Cache + // --------------------------------------------------------------------------- + /** Cached protocol stats entry per contract address. */ + private _protocolStatsCache: Map = new Map(); /** * OpenTelemetry handle.
