From 5a36ae20d48e09ace45649147b93dfe779af16fa Mon Sep 17 00:00:00 2001 From: Claude Date: Wed, 21 Jan 2026 14:56:39 +0000 Subject: [PATCH 01/25] feat: add automatic CTWA (Click-to-WhatsApp) ads message recovery Messages from Facebook/Instagram ads (Click-to-WhatsApp) don't arrive on linked devices because Meta's ads endpoint doesn't encrypt for multi-device. They arrive as "Message absent from node" placeholders. This change automatically requests the message from the primary phone via PDO (Peer Data Operation) when a CTWA placeholder is detected. Changes: - Add enableCTWARecovery config option (default: true) - Trigger requestPlaceholderResend() for "Message absent from node" errors - Add Prometheus metrics for CTWA recovery tracking - Add comprehensive unit tests for CTWA recovery functionality Resolves: https://github.com/WhiskeySockets/Baileys/issues/1723 Resolves: https://github.com/WhiskeySockets/Baileys/issues/1034 ---

Instead of maintaining the version number in 3 separate files (baileys-version.json, index.ts, generics.ts), this change makes baileys-version.json the single source of truth. Other files now import the version from this JSON file. This follows the DRY principle and reduces: - Risk of version inconsistency across files - Maintenance burden (only 1 file to update) - PR diff size (3 files → 1 file for version updates) - Merge conflict probability Addresses inefficiency found in Baileys PR #2269. --- scripts/update-version.ts | 166 ++++++++++++++++++-------------------- src/Defaults/index.ts | 4 +- src/Utils/generics.ts | 5 +- 3 files changed, 85 insertions(+), 90 deletions(-) diff --git a/scripts/update-version.ts b/scripts/update-version.ts index f540f9d3..6401959e 100644 --- a/scripts/update-version.ts +++ b/scripts/update-version.ts @@ -1,40 +1,101 @@ #!/usr/bin/env node /** -

Fix #1,6: Use connection.update event instead of overriding sock.end() - Listens for 'close' event to cleanup interval - Handles both explicit close and internal disconnections 2. Fix #3: Exit code 2 when fetch fails (not 0) - Allows CI to distinguish success/error/fetch-failed - Properly signals fetch failures to workflows 3. Fix #4: Document revision bounds + add env vars - Added detailed comments explaining min/max revision values - Made configurable via WA_MIN_REVISION/WA_MAX_REVISION env vars 4. Fix #5,9: Remove unused fetchLatestVersion option - Removed from SocketConfig and defaults - Updated versionCheckIntervalMs docs to clarify it's only for makeWASocketAutoVersion 5. Fix #7: Use separate variable for version tracking - trackedVersion instead of mutating mergedConfig - Prevents unexpected side effects 6. Fix #8: Check socket state before emitting events - isSocketClosed flag to prevent race conditions - Double-check after async operations 7. Fix #10: Implement force parameter in workflow - Creates PR even without version changes when force=true - Useful for re-triggering updates manually Note: Test coverage (Fix #2) deferred to separate PR due to ESM mocking complexity with Jest. --- .github/workflows/update-version.yml | 77 ++++++++++++++++++++++---- scripts/update-version.ts | 54 ++++++++++++++++--- src/Defaults/index.ts | 1 - src/Socket/index.ts | 81 ++++++++++++++++++---------- src/Types/Socket.ts | 11 ++-- 5 files changed, 172 insertions(+), 52 deletions(-) diff --git a/.github/workflows/update-version.yml b/.github/workflows/update-version.yml index 5399ca3b..2ccfeb82 100644 --- a/.github/workflows/update-version.yml +++ b/.github/workflows/update-version.yml @@ -7,9 +7,10 @@ on: workflow_dispatch: inputs: force: - description: 'Force update even if version is the same' + description: 'Force create PR even if version unchanged (useful for re-triggering)' required: false default: 'false' + type: boolean permissions: contents: write @@ -47,23 +48,52 @@ jobs: - name: Update WhatsApp Web Version id: update_version - run: yarn update:version + run: | + # Run the update script, capture exit code + # Exit codes: 0=success, 1=error, 2=fetch failed (fallback used) + set +e + yarn update:version + EXIT_CODE=$? + set -e + + echo "exit_code=$EXIT_CODE" >> $GITHUB_OUTPUT + + # Only fail on fatal errors (exit code 1) + if [ $EXIT_CODE -eq 1 ]; then + echo "::error::Script failed with fatal error" + exit 1 + fi + + # Exit code 2 means fetch failed but fallback was used - this is a warning + if [ $EXIT_CODE -eq 2 ]; then + echo "::warning::Could not fetch latest version from WhatsApp servers" + fi - name: Check for changes id: check_changes run: | + FORCE="${{ inputs.force }}" + if git diff --quiet; then echo "has_changes=false" >> $GITHUB_OUTPUT + if [ "$FORCE" == "true" ]; then + echo "force_mode=true" >> $GITHUB_OUTPUT + echo "::notice::Force mode enabled - will create PR even without changes" + else + echo "force_mode=false" >> $GITHUB_OUTPUT + fi else echo "has_changes=true" >> $GITHUB_OUTPUT + echo "force_mode=false" >> $GITHUB_OUTPUT fi - name: Create Pull Request - if: steps.check_changes.outputs.has_changes == 'true' + if: steps.check_changes.outputs.has_changes == 'true' || steps.check_changes.outputs.force_mode == 'true' env: GH_TOKEN: ${{ secrets.GITHUB_TOKEN }} run: | BRANCH_NAME="update-version/stable" + FORCE="${{ inputs.force }}" # Configure git git config user.name "github-actions[bot]" @@ -72,25 +102,40 @@ jobs: # Check if branch exists and delete it git push origin --delete "$BRANCH_NAME" 2>/dev/null || true - # Create new branch, commit, and push + # Create new branch git checkout -b "$BRANCH_NAME" # Only add the single source of truth file git add src/Defaults/baileys-version.json - git commit -m "chore: update WhatsApp Web version" + + # Create commit (allow empty if force mode) + if [ "$FORCE" == "true" ] && git diff --cached --quiet; then + git commit --allow-empty -m "chore: force WhatsApp Web version check" + else + git commit -m "chore: update WhatsApp Web version" + fi + git push origin "$BRANCH_NAME" # Create PR using GitHub CLI - gh pr create \ - --title "chore: update WhatsApp Web version" \ - --body "Automated WhatsApp Web version update. + PR_BODY="Automated WhatsApp Web version update.

bc7fcca45facc863688f1ceabcdbb14d58a6232f Mon Sep 17 00:00:00 2001 From: Claude Date: Thu, 22 Jan 2026 15:14:29 +0000 Subject: [PATCH 25/25] fix: initialize metrics with labels to show zero values in Prometheus Metrics with labels only appear in Prometheus output after being incremented at least once. This fix pre-initializes all labeled metrics with zero values so they appear in Grafana dashboards immediately, including buffer_destroyed_total which was showing "No data". --- src/Utils/prometheus-metrics.ts | 47 +++++++++++++++++++++++++++++++++ 1 file changed, 47 insertions(+) diff --git a/src/Utils/prometheus-metrics.ts b/src/Utils/prometheus-metrics.ts index 4543d383..c24a43fe 100644 --- a/src/Utils/prometheus-metrics.ts +++ b/src/Utils/prometheus-metrics.ts @@ -2104,12 +2104,59 @@ export function getMetricsManager(config?: Partial): PrometheusMe return globalMetricsManager } +/** + * Initialize metrics with labels to zero values + * This ensures they appear in Prometheus output even before first increment + */ +function initializeMetricsWithLabels(): void { + try { + // Buffer destroyed metric + metrics.bufferDestroyed?.inc({ reason: 'normal', had_pending_flush: 'true' }, 0) + metrics.bufferDestroyed?.inc({ reason: 'normal', had_pending_flush: 'false' }, 0) + metrics.bufferDestroyed?.inc({ reason: 'error', had_pending_flush: 'true' }, 0) + metrics.bufferDestroyed?.inc({ reason: 'error', had_pending_flush: 'false' }, 0) + + // Buffer flushes metric + metrics.bufferFlushes?.inc({ type: 'event', reason: 'normal' }, 0) + metrics.bufferFlushes?.inc({ type: 'event', reason: 'forced' }, 0) + + // Connection metrics + metrics.connectionAttempts?.inc({ status: 'success' }, 0) + metrics.connectionAttempts?.inc({ status: 'failure' }, 0) + metrics.connectionErrors?.inc({ error_type: 'timeout' }, 0) + metrics.connectionErrors?.inc({ error_type: 'closed' }, 0) + metrics.connectionErrors?.inc({ error_type: 'unknown' }, 0) + + // Message metrics + metrics.messagesSent?.inc({ type: 'text' }, 0) + metrics.messagesSent?.inc({ type: 'media' }, 0) + metrics.messagesSent?.inc({ type: 'other' }, 0) + metrics.messagesReceived?.inc({ type: 'text' }, 0) + metrics.messagesReceived?.inc({ type: 'media' }, 0) + metrics.messagesReceived?.inc({ type: 'notification' }, 0) + metrics.messagesReceived?.inc({ type: 'other' }, 0) + metrics.messageRetries?.inc({ type: 'text' }, 0) + metrics.messageRetries?.inc({ type: 'other' }, 0) + metrics.messageFailures?.inc({ type: 'text', reason: 'max_retries' }, 0) + metrics.messageFailures?.inc({ type: 'other', reason: 'max_retries' }, 0) + + // Circuit breaker metric + metrics.circuitBreakerTrips?.inc({ name: 'main' }, 0) + + console.log('[Prometheus] Initialized metrics with labels') + } catch (error) { + console.error('[Prometheus] Error initializing metrics with labels:', error) + } +} + /** * Initialize global metrics (call once at application startup) */ export async function initializeMetrics(config?: Partial): Promise { const manager = getMetricsManager(config) await manager.initialize() + // Initialize metrics with labels to zero values + initializeMetricsWithLabels() return manager }
