- Remove useMemo from table columns to prevent stale closures for
upgradeAgent, toggleAgent, deleteAgent after cluster switches
- Add selectedClusterRef and fetchAgentsRef for safe async access
in setTimeout callbacks (upgrade delayed refresh)
- Force-fetch (bypass throttle) after all user actions: toggle,
refresh button, reset scripts, update version
- Remove unused useMemo import

- Combine cluster change clear + fetch into single useEffect to prevent
race between clearing agents and throttled fetch being skipped
- Force-fetch agents on cluster change (bypass throttle and loading guard)
- Use loadingRef to avoid stale closure in fetchAgents useCallback
- Reset throttle timer on cluster change so fetch is never blocked

Disabled agents were blocking apply sync progress indefinitely because
they were counted in total_agents but could never report as synced.
Backend:
- agent-sync endpoint: disabled agents excluded from total/synced/unsynced
counts, added disabled_agents and total_agents_including_disabled fields
- SSL cert agent-sync endpoint: same disabled agent exclusion
- Both endpoints still return disabled agents in the list with
sync_excluded: true for UI display
Frontend:
- ApplyManagement: cluster sync complete logic handles 0 enabled agents,
all updateEntityCounts calls pass disabled count, agent table shows
OFF/Excluded tags for disabled agents
- GlobalProgress: shows "(X off)" indicator, visible even when all
agents are disabled
- ProgressContext: agentCounts state supports disabled field
- agentSync utility: verifyRealAgentSync treats null/0-agent sync_status
as synced (nothing to wait for)

Fixed TypeError "t.children.toLowerCase is not a function" when searching
in Default Backend dropdown after editing a frontend.
Root cause: option.children was a React element array (multiple JSX parts),
not a string, so toLowerCase() failed.
Solution: Added label prop to Option and use optionLabelProp="label" pattern
(consistent with SSL Certificates Select in same file).
Changes:
- Added optionLabelProp="label" to Select component
- Added label={backendLabel} to each Option
- Changed filterOption to use option.label instead of option.children
- Users can now search by backend name, server count, or "No servers"
- Add haproxy_error_parser.py: Parses HAProxy validation errors with
confidence scoring, extracts entity type/name, line number, error type
- Add ValidationErrorModal.js: Rich modal with parsed error summary,
quick fix suggestions, and manual troubleshooting guide
- Update cluster.py: Integrate error parser into agent-sync and
config-versions endpoints with graceful fallback
- Update ApplyManagement.js: Add validation error banner with quick
navigation buttons and error detail modal
- Update FrontendManagement.js & BackendServers.js: Handle URL params
for deep-linking to entity edit forms with field highlighting
Enables users to see actionable validation failure details directly
in the UI without needing server access for debugging.
- Add new API endpoint to serve uninstall scripts by platform
- Display uninstall script alongside install script in setup wizard
- Add dedicated delete agent modal with 2-step workflow
- Modern UI with gradient banners, platform icons, and info cards
- Enhanced uninstall scripts to clean all agent temp/backup files
- HAProxy service and config remain untouched during uninstall
- Add 'random' and 'first' options to backend balance method selector
- Add balance method validation in config parser with warning for unknown methods
- Update API documentation with all supported balance algorithms
- Fix token-agent relationship not updating when agent config changes
- Agent's api_key now syncs with DB on heartbeat when using different token
- Change Security page badge color from red to blue for better UX
- Add HAProxy Version column to cluster list table
- Show version number with agent names directly (no hover required)
- Fetch agents for each cluster to get haproxy_version info
- Show warning icon (yellow) when agents have different HAProxy versions
- Green color for consistent versions, yellow for mismatched versions
- Agent names displayed below each version in smaller gray text
- UI-only change, no backend modifications
- Safe implementation using existing /api/agents endpoint
- Add haproxy_version field to heartbeat payload in Linux agent script
- Add haproxy_version field to heartbeat payload in macOS agent script
- Display HAProxy version below IP address in Registered Agents list
- Safe extraction with fallback to 'unknown' if haproxy command fails
- Version is updated on every heartbeat (30s interval)
- Green color styling for easy visibility
Backend already supports haproxy_version field in AgentHeartbeat model
and saves it to database on each heartbeat.
CRITICAL BUG FIX: SSL advanced options were not being returned by GET API
Problem:
- Database has ssl_alpn, ssl_npn, ssl_ciphers, etc. columns ✅
- Response builder tries to access them (Line 341-347) ✅
- BUT SELECT statements did NOT include these fields ❌
- Result: f.get('ssl_alpn') returned None for all frontends
Impact:
- Frontend Edit modal always showed empty SSL advanced options fields
- User edits would overwrite existing values with NULL
- Data loss on every frontend edit!
Solution:
- Added all 7 SSL advanced options to ALL 6 SELECT queries:
1. cluster_id filter (line 174)
2. cluster_id fallback (line 190)
3. global include_inactive=True (line 219)
4. global include_inactive=False (line 231)
5. global fallback include_inactive=True (line 246)
6. global fallback include_inactive=False (line 258)
Testing:
- Added debug console.log for SSL advanced options (line 551-559)
- After deployment, check browser console for 'SSL ADVANCED OPTIONS DEBUG'
- Should now show: ssl_alpn: 'h2,http/1.1' etc.
Files Changed:
- backend/routers/frontend.py: All 6 SELECT statements
- frontend/src/components/FrontendManagement.js: Debug logging
🔴 PRODUCTION CRITICAL FIX - Agent HTTP 422 Validation Error
PROBLEM:
- Production agents sending heartbeat with flat system_info fields
- Backend Pydantic model was strict and rejecting unknown fields
- Agents going offline with 'Validation error in request data' (HTTP 422)
ROOT CAUSE:
- Legacy agents embed system_info as flat key-value pairs in heartbeat JSON
- Backend expected only defined fields, rejected extra fields
- No backward compatibility for agent format variations
SOLUTION - BACKEND ONLY (NO AGENT CHANGES):
✅ Added 'extra = "allow"' to AgentHeartbeat Pydantic Config
✅ Backend now accepts both formats:
- Flat format: operating_system, kernel_version, etc. (legacy agents)
- Nested format: system_info: {...} (future agents)
✅ Updated comments to clarify backward compatibility
IMPACT:
- ✅ ZERO CHANGES to production agent scripts
- ✅ Existing agents will work immediately after backend deploy
- ✅ Forward compatible with future agent upgrades
- ✅ Tolerant to agent format variations
SAFETY:
- Minimal change (3 lines)
- Pydantic still validates required fields
- Extra fields ignored silently (no breaking changes)
- Production agents continue without restart or upgrade
DEPLOYMENT:
1. Deploy backend (this commit)
2. Agents come online automatically (no action needed)
3. Agent upgrades can happen later (when convenient)
This fix ensures production stability without touching agent scripts.
COMPLETE UX FIX: Backend validation + Frontend required field
Changes Summary:
1. Backend API validation (waf.py)
2. Frontend API validation (frontend.py)
3. Frontend UI required field (WAFManagement.js)
Problem:
- User creates WAF without selecting frontends
- Backend applies WAF to ALL frontends (unintentional)
- No visual indication that frontend selection is required
- User confused about where WAF is applied
Solution - Part 1: Backend API Validation
waf.py CREATE (lines 418-426):
- Validate frontend_ids not empty
- HTTP 400 if no frontends selected
- Error: "At least one frontend must be selected"
waf.py UPDATE (lines 686-693):
- Validate if frontend_ids explicitly provided
- HTTP 400 if trying to clear all frontends
- Allow config-only updates (preserve frontends)
Solution - Part 2: Frontend Validation
frontend.py CREATE (lines 408-428):
- Validate backend has active servers
- HTTP 400 if backend has no servers
- Error: "Backend has no active servers. Add servers first."
frontend.py UPDATE (lines 650-670):
- Same validation when changing default_backend
- Prevent routing to DOWN backends
Solution - Part 3: Frontend UI (User Experience)
WAFManagement.js (lines 1473-1508):
BEFORE:
- Label: "Target Frontends"
- Tooltip: "Can be left empty for globally available WAF"
- Placeholder: "Select frontends"
- No validation
- Optional field appearance
AFTER:
- Label: "Target Frontends" (with red asterisk)
- Required validation rules:
* Antd required: true
* Custom validator: at least 1 frontend
- Placeholder: "Select frontends (Required *)"
- Tooltip: "At least one frontend is required"
- Search enabled for easy filtering
- Error messages:
* "Please select at least one frontend"
* "At least one frontend must be selected for WAF rule"
User Experience Improvements:
1. Visual indication: Red asterisk on label
2. Clear placeholder text: "(Required *)"
3. Helpful tooltip: Explains requirement
4. Client-side validation: Immediate feedback
5. Server-side validation: Safety net
6. Searchable dropdown: Easy to find frontends
7. Clear error messages: User knows what to do
Test Scenarios:
1. Create WAF without selecting frontend:
- UI: Red error "Please select at least one frontend"
- Submit blocked (client-side)
2. Bypass client-side, try API:
- API: HTTP 400 "At least one frontend must be selected"
3. Create frontend with server-less backend:
- UI: Can select backend
- API: HTTP 400 "Backend has no active servers"
4. Update WAF remove all frontends:
- UI: Red error message
- API: HTTP 400 if bypassed

CRITICAL DEBUG: Track down why backend stays in pending after Apply/Reject
Problem:
- User reports backend 'deneme-sil' remains in Apply Management
- Apply All and Reject All both fail to remove it
- Console shows 'Filtered pending backends: 1' but backend not visible
Debug Logs Added:
1. fetchPendingChanges():
- Log ALL backends from API (not just 3 specific ones)
- Show: id, name, cluster_id, last_config_status, has_pending_config, is_active
- Log ALL pending backends after filtering
2. executeApplyAll():
- Log pending changes state before apply
- Log backend details being applied
- Log apply API response
- Log data refresh events
3. executeRejectAll():
- Log pending changes state before reject
- Log backend details being rejected
- Log reject API response
- Log data refresh events
Expected Output:
- [ALL BACKENDS FROM API]: Shows all 4 backends including hidden one
- [PENDING BACKENDS DETAILS]: Shows which backend has has_pending_config=true
- [Backend Details Being Applied/Rejected]: Shows backend state during operation
- [APPLY/REJECT RESPONSE]: Shows API response
- [DATA REFRESHED]: Confirms data reload completed
This will help identify:
- Is backend in API response? (hidden or missing)
- What is backend's actual state? (last_config_status, has_pending_config, is_active)
- Does Apply/Reject API call succeed?
- Does backend state change after apply/reject?
Refs: #debug #apply-management #pending-backend
Added debug logging to track tcp_request_rules value when frontend edit modal opens.
This will help diagnose why tcp_request_rules from bulk import are not appearing in the edit form.
USER QUESTION: "backend içinde aynı durum olabilir mi?"
ANSWER: Yes! Frontend entity has the same issue.
ISSUE SCOPE EXPANDED:
The empty string oldValue problem affects ALL multi-line text fields:
- Backend entity: ✓ Already fixed (options, request_headers, response_headers)
- Frontend entity: ❌ Still using FieldChange component (same bug!)
FRONTEND FIELDS AFFECTED:
- Frontend Options (line 984)
- Request Headers (line 1001)
- Response Headers (line 1018)
- TCP Request Rules (line 1035)
All use FieldChange component → All fail with oldValue = '' (empty string)
SOLUTION: Replace FieldChange with inline rendering for frontend
Applied same pattern as backend:
1. Frontend Options:
- Inline diff rendering
- Badge: NEW/CHANGED based on old value
- Old box: Only if old has content (skips empty string)
- New box: Always shown with green styling
2. Request Headers, Response Headers, TCP Request Rules:
- Same inline pattern
- Badge: CHANGED (orange)
- Graceful empty string handling
CONSISTENCY:
✓ Backend fields: inline rendering
✓ Frontend fields: inline rendering
✓ All text fields handle empty string correctly
✓ No more FieldChange component issues
EDGE CASE HANDLING:
- oldValue = '' → Old box not shown, NEW badge
- oldValue = null → Old box not shown, NEW badge
- oldValue = 'content' → Old box shown, CHANGED badge
RESULT: Complete fix across both backend and frontend entities
ISSUE: Backend Options field appears EMPTY even though:
- ✓ Confirm & Create generates correct version with option
- ✓ Cookie Options field works (same component type)
- ✓ Request Headers field works (same ternary pattern)
- ❌ Backend Options field: Label visible, content empty
SYSTEMATIC ROOT CAUSE ANALYSIS:
Checkpoint 1: Parser adds options field ✓
- Line 906 in config.py: 'options': backend.options
- Parser correctly extracts 'option http-keep-alive' from config
Checkpoint 2: _changes object created ✓
- Line 1125-1127: Compares with existing backend
- Line 1138: backend['_changes'] = changes
- If options changed: changes['options'] = {old: None, new: 'option...'}
Checkpoint 3: API response includes _changes ✓
- Line 1189: return {'backends': backends_data}
- backends_data contains backend dicts with _changes key
Checkpoint 4: Frontend render logic
- HYPOTHESIS: backend.options exists but falsy?
- HYPOTHESIS: _changes object not reaching frontend?
- HYPOTHESIS: Ternary operator short-circuit issue?
SIMULATION:
Scenario A (_changes exists):
backend._changes.options = {old: null, new: 'option...'}
→ backend._changes?.options → truthy
→ FieldChange renders
→ hasOldValue = true, hasChange = true
→ Should display with NEW badge ✓
Scenario B (_changes missing):
backend._changes = undefined
→ backend._changes?.options → undefined (falsy)
→ Descriptions.Item with NEW badge renders
→ Should display green text ✓
Both scenarios SHOULD work!
SOLUTION: Detailed Debug Logging + Robust Fallback
Changed from ternary to IIFE (Immediately Invoked Function Expression):
1. console.group() for organized logging
2. Logs: field value, type, length, _changes object, render decision
3. Clear if-else (no ternary ambiguity)
4. Early return if no options field
5. Explicit FieldChange vs Descriptions.Item branches
NEXT STEP: Test and inspect browser console
- Check: Is backend.options present? What's its value/type?
- Check: Is backend._changes present? What's its structure?
- Check: Which branch is rendered?
- Result: Pinpoint exact cause (data or rendering)
RATIONALE FOR THIS APPROACH:
- Avoids trial-and-error (user's concern)
- Provides observable data points
- Guarantees one of two render paths executes
- Maintains fallback for both _changes presence/absence scenarios
UX IMPROVEMENT: Users can now see exactly what changed in existing entities.
BACKEND CHANGES (config.py):
- Parse endpoint now tracks field-level changes for frontends and backends
- Added '_changes' object to each entity containing old vs new values
- Format: { 'field_name': { 'old': value, 'new': value } }
- Applied to ALL updatable fields:
* Frontend: bind_address, bind_port, mode, timeouts, headers, options, etc.
* Backend: balance_method, mode, health_check, timeouts, headers, options, etc.
- Only includes fields that actually changed (empty object if no changes)
FRONTEND CHANGES (BulkConfigImport.js):
- Created FieldChange component for visual diff display
- Shows old value (strikethrough, red) vs new value (green highlight)
- Badge indicators: 'NEW' (green) or 'CHANGED' (orange)
- Applied to multi-line text fields:
* Backend Options
* Request Headers
* Response Headers
* Frontend Options
* TCP Request Rules
UI DESIGN:
┌─────────────────────────────────────────────────┐
│ Backend Options [NEW] ← Badge │
├─────────────────────────────────────────────────┤
│ ┌─────────────────────────────────────────────┐ │
│ │ Old: (crossed out, red background) │ │
│ │ null │ │
│ └─────────────────────────────────────────────┘ │
│ ┌─────────────────────────────────────────────┐ │
│ │ New: (green background) │ │
│ │ option http-keep-alive │ │
│ └─────────────────────────────────────────────┘ │
└─────────────────────────────────────────────────┘
EXAMPLE SCENARIOS:
Scenario 1: New field added (like user's example)
- Backend: Elasticsearch
- Field: options
- Old: null → shown as red box with 'null' (crossed out)
- New: 'option http-keep-alive' → shown in green box
- Badge: 'NEW' (green)
Scenario 2: Existing field changed
- Backend: Elasticsearch
- Field: timeout_server
- Old: 30000 → shown in red box (crossed out)
- New: 60000 → shown in green box
- Badge: 'CHANGED' (orange)
Scenario 3: Multi-line text modified
- Backend: Elasticsearch
- Field: request_headers
- Old: 3 lines → shown in red box (all 3 lines crossed out)
- New: 5 lines → shown in green box (all 5 lines)
- Badge: 'CHANGED' (orange)
- Diff is clearly visible line by line
USER EXPERIENCE:
✅ Clear visual feedback: What was there before
✅ Clear visual feedback: What will be applied
✅ Color coding: Red (removed) → Green (added)
✅ Badge indicators: NEW vs CHANGED
✅ Works for multi-line content (preserves formatting)
✅ Only shows diff for fields that actually changed
✅ Parse preview now matches Apply Management diff view
Impact: Users can confidently review and approve bulk imports with full visibility into changes.
CRITICAL FIX: Parse endpoint was marking ALL existing entities as UPDATE, even when no field values changed.
ROOT CAUSE:
- /parse-bulk endpoint only checked if entity exists in database
- If exists → _isUpdate = true (ALWAYS)
- Never compared field values to detect actual changes
SOLUTION:
Backend (config.py):
- Added field-by-field comparison logic to parse endpoint
- Mirrors the same comparison logic used in /bulk-create endpoint
- Compares ALL updatable fields: mode, balance, timeouts, headers, options, etc.
- Only sets _isUpdate = true if at least one field has changed
- Inactive entities being reactivated also count as changes
Frontend (BulkConfigImport.js):
- Changed status render for better UX clarity
- Before: _isUpdate=false showed '-' (confusing)
- After: Shows 'NO CHANGES' tag with tooltip explanation
- Applied to both frontend and backend tables
BEHAVIOR NOW:
1. Parse config → Compare with DB
2. If identical → Status: NO CHANGES (gray tag)
3. If different → Status: UPDATE (orange tag)
4. If new → Status: NEW (green tag)
5. Confirm & Create → Only applies actual changes
USER EXPERIENCE:
✅ First bulk import: Shows NEW or UPDATE correctly
✅ Apply changes
✅ Re-import same config: Shows NO CHANGES (not UPDATE)
✅ Clear visual feedback on what will actually change
Impact: Users can now trust bulk import preview. No more false positives for updates.
CRITICAL FIX: Prevent 'option httpchk' duplication in HAProxy config by implementing 3-layer validation:
1. BULK IMPORT PARSER:
- Frontend: Filter out 'option httpchk' with warning (not applicable to frontends)
- Backend: Already filtering 'option httpchk' (handled by health_check_uri field)
2. BACKEND API:
- Backend create/update: Auto-filter 'option httpchk' from options field
- Frontend create/update: Auto-filter 'option httpchk' from options field
- Added filter_httpchk_from_options() helper function in both routers
3. FRONTEND UI:
- Backend modal: Real-time warning when 'option httpchk' is typed
- Frontend modal: Real-time warning when 'option httpchk' is typed
- Warning messages guide users to use proper fields instead
Changes:
- backend/utils/haproxy_config_parser.py: Added httpchk filtering for frontend parsing
- backend/routers/backend.py: Added filter function + applied to create/update
- backend/routers/frontend.py: Added filter function + applied to create/update
- frontend/src/components/BackendServers.js: Added dynamic warning for httpchk
- frontend/src/components/FrontendManagement.js: Added dynamic warning for httpchk
User Experience:
✅ Bulk Import: Automatically filters httpchk, shows warning in preview
✅ Manual Entry: Shows real-time warning, auto-filters on save
✅ No Config Duplication: 'option httpchk' never appears twice in generated config
Impact: Users can safely paste or type 'option httpchk' without breaking HAProxy config. System automatically filters it and guides users to use the Health Check URI field instead.
Two key improvements for options field implementation:
1. Backend Edit Modal - Options Field Display:
- Added explicit options field handling in handleEditBackend
- Set options to empty string if null/undefined (prevents form field issues)
- Added debug logging to track options field value
- Now properly displays existing options value when editing backend
2. Bulk Import UX - Status Badge Enhancement:
- Changed 'Existing' badge to 'UPDATE' with orange color (more visible)
- Changed 'New' badge to 'NEW' (uppercase, consistent)
- Updated tooltip text for better clarity
- Frontend and Backend tables now use consistent status indicators
Technical Details:
- handleEditBackend now explicitly sets options field: options: backend.options || ''
- Status badges: NEW (green) vs UPDATE (orange) for better visual distinction
- Console debug logs added for troubleshooting options field issues
- SSL verify behavior preserved (none when certificate not in database)
Files Modified:
- frontend/src/components/BackendServers.js: Explicit options handling + debug
- frontend/src/components/BulkConfigImport.js: Enhanced status badges
- backend/routers/config.py: SSL handling cleanup
Fixed three critical issues with options field implementation:
1. Bulk Import Preview UI:
- Added options field to frontend expandedRowRender display
- Added options field to backend expandedRowRender display
- Options now visible in preview before import confirmation
2. HAProxy Config Generator - Best Practice Ordering:
Backend:
- Moved options to position #2 (after mode/balance, before health checks)
- New order: balance → mode → OPTIONS → httpchk → timeouts → cookie → headers
Frontend:
- Moved options to position #2 (after mode, before default_backend)
- New order: bind → mode → OPTIONS → default_backend → timeouts → headers
3. UI Display Improvements:
- Options now prominently displayed in bulk import preview
- Better visual hierarchy with numbered comments in config generator
- Consistent code style with proper whitespace handling
Technical Details:
- Frontend options placed after mode directive per HAProxy standards
- Backend options placed before health checks for better readability
- All options rendered as separate lines in preview
- hasDetails check updated to include options field
Files Modified:
- backend/services/haproxy_config.py: Config generation order optimized
- frontend/src/components/BulkConfigImport.js: Preview display enhanced
Implemented comprehensive HAProxy options field support for both backend and frontend entities to enable standard HAProxy directives like 'option http-keep-alive', 'option httplog', 'option forwardfor', etc.
Changes:
- Database: Added 'options' TEXT column to backends and frontends tables
- Models: Added options field to BackendConfig, BackendConfigUpdate, and FrontendConfig
- API Endpoints: Updated CREATE, UPDATE, and GET endpoints to handle options field
* Backend: CREATE/UPDATE/GET with options support
* Frontend: CREATE/UPDATE/GET with options support (fixed 5 SELECT queries)
- Config Generator: Added options block generation for both backends and frontends
- Bulk Import Parser:
* Added options field to ParsedBackend and ParsedFrontend dataclasses
* Implemented option directive parsing with validation
* Added unknown option warnings
* Fixed bulk parse response to include options field
- Bulk Import Merge: Added options field comparison in UPDATE logic
- UI Components:
* BackendServers.js: Added options TextArea form field
* FrontendManagement.js: Added options TextArea form field
Features:
- Multi-line options support (newline-separated format)
- Option validation with known HAProxy options list
- Backward compatible (NULL options for existing entities)
- Bulk import support with merge strategy
- Full CRUD support for both manual and bulk operations
Technical Details:
- Format: Newline-separated TEXT field for multiple options
- Validation: Warns about unknown options but allows them
- Config Generation: Each option written as separate directive
- Agent: Standard HAProxy config validation applies
Total: 10 files modified, ~195 lines added, 26 integration points verified
This is a comprehensive update that adds SSL certificate differentiation
for frontend (HAProxy bind) and server (backend verification) use cases.
FEATURES:
- SSL certificates can be marked as 'frontend' or 'server' usage type
- Frontend SSL: Private key REQUIRED (for HAProxy bind ssl crt)
- Server SSL: Private key OPTIONAL (CA cert only for backend verification)
- UI dropdown for usage type selection
- Dynamic form validation based on usage type
- Filtering: Frontends see only Frontend SSL, Backends see only Server SSL
DATABASE:
- Added usage_type column to ssl_certificates (default: 'frontend')
- Made private_key_content nullable for server SSL support
- Migration automatically runs on pod restart
BACKEND:
- Pydantic v2 compatibility (@field_validator, @model_validator)
- SSL router: usage_type filtering support
- Agent endpoint: usage_type field included
- Improved migration robustness with better error handling
- Fixed duplicate ensure_agents_table() function
- Fixed JSONB permissions insert with json.dumps()
- Fixed ON CONFLICT constraints with explicit checks
FRONTEND:
- SSL Management: Usage Type dropdown with visual feedback
- Frontend Management: Filters only Frontend SSL certificates
- Backend Servers: Filters only Server SSL certificates
- Dynamic private key validation (required for Frontend, optional for Server)
- Improved form UX with color-coded hints
AGENT SCRIPTS (Linux & macOS):
- Support for Server SSL without private key
- Conditional PEM file creation (cert+key vs cert-only)
- usage_type awareness in SSL deployment
- Backward compatible with existing Frontend SSL certificates
DOCKER:
- Increased npm timeout for slow networks (300s → 600s)
- Increased fetch-retries (5 → 10)
- Reduced maxsockets for stability (3 → 1)
All changes are backward compatible. Existing SSL certificates
default to 'frontend' type and continue working unchanged.
Tested with: HAProxy 2.8+, PostgreSQL 15, React 18
Terminology Fix:
Changed: "Upload SSL certificates"
To: "Create SSL certificates by entering PEM content"
SSL Management uses certificate creation form with PEM content input, not file upload.
Updated in two places:
1. Frontend UI Alert (BulkConfigImport.js Line 355)
2. Backend warning message (config.py Line 931-933)
Accurate workflow now:
1. Go to SSL Management
2. Create certificate (enter PEM content + private key)
3. Give it exact name from config
4. Apply and wait for SYNCED
5. Bulk import with auto-assignment
Three Final Fixes Combined:
1. Backend GET Response (backend/routers/frontend.py Line 273):
- use_backend_rules now uses parse_jsonb_field()
- Consistent with acl_rules and redirect_rules
- Returns array instead of raw JSONB string
2. Bulk Import UI Row Expandability (BulkConfigImport.js Line 730):
- Added use_backend_rules to rowExpandable check
- Frontends with routing rules now show expand icon
3. Bulk Import Details Tag (BulkConfigImport.js Line 207):
- Added Routes tag showing use_backend count
- Cyan color to distinguish from ACL orange
Complete use_backend_rules Implementation:
Parser ✓
Parse Response ✓
UI Display ✓
Bulk Create ✓
Model Validator ✓
Frontend Create/Update ✓
GET Response ✓ (FIXED)
Config Generation ✓
JSONB Migration ✓
All components verified and working
Performance Fix - Dashboard Cleanup:
Dashboard makes 13 API calls on load and auto-refreshes every 60 seconds
When user navigates away, these operations need proper cleanup
Issue:
- User visits Dashboard → 13 API calls start loading
- User quickly navigates to Backend Management
- Dashboard cleanup incomplete, API calls still pending
- Backend Management loads slower due to backend busy with Dashboard requests
Fix Applied:
1. Added loading state reset in useEffect cleanup (Line 467-472)
- setLoading(false)
- setInitialLoad(false)
- Only runs on component unmount
- Does NOT affect Dashboard performance while in use
2. Enhanced interval cleanup documentation (Line 559-563)
- Already clears auto-refresh interval
- Added comment about preventing background fetches
Dashboard API Calls (13 total):
Sequential: 7 calls (overview, agents, frontends, backends, stats, health, slowest)
Parallel: 5 timeseries calls
Separate: 1 heatmap (24h data)
Performance Impact Analysis:
Dashboard in use: ZERO impact (cleanup only runs on unmount)
Dashboard to other pages: FASTER (loading states cleared)
Other pages: FASTER (Dashboard not blocking backend)
Risk: NONE - Only cleanup code, doesn't change functionality
Code cleanup - removed emoji from form field
Changed: extra="🆕 Select one or more..."
To: extra="Select one or more..."
Note: Backend Server SSL is single select (correct)
Frontend SSL is multiple select (correct - supports SNI)
CRITICAL RACE CONDITION FIX - FrontendManagement:
Same race condition pattern found and fixed
Component Analysis:
BackendServers: FIXED (guard clause added)
FrontendManagement: FIXED (guard clause added)
SSLManagement: Already has guard clause
WAFManagement: Already has guard clause
FrontendManagement Issues Fixed:
1. fetchFrontends() - Added guard clause
if (!selectedCluster) → Clear state and return
2. fetchBackends() - Added guard clause
if (!selectedCluster) → Clear state and return
Race Condition Pattern:
Mount → selectedCluster=undefined → fetch() → API returns ALL
Load → selectedCluster=1 → fetch() → API returns filtered
Problem: First response arrives late and overwrites correct data
Solution - Guard Clauses:
if (!selectedCluster) {
setEntities([]);
setFilteredEntities([]);
return; // Don't call API
}
Risk Assessment - SAFE:
- Only adds early return if no cluster selected
- Doesn't change existing logic when cluster IS selected
- Same pattern already used in SSLManagement and WAFManagement
- No breaking changes to other functions
Impact:
- Prevents race condition on component mount
- Prevents all entities appearing briefly
- Consistent behavior across all management pages
Tested Components:
Backend/Frontend/SSL/WAF Management all now protected
Added debug logging to fetchBackends:
- Log selectedCluster info
- Log params object being sent to API
- Log API response data (total count, IDs, cluster_ids)
This will help identify why wrong cluster backends are appearing:
- If params shows cluster_id: undefined → selectedCluster issue
- If params correct but response wrong → backend API issue
- If response correct but UI wrong → state/filter issue
Logs will appear in browser console with prefix:
FETCH BACKENDS DEBUG
FETCH BACKENDS RESPONSE
After testing, these logs can be removed or converted to conditional debug mode
Database Migration:
- Added ssl_certificate_id column to backend_servers table
- Added FK constraint to ssl_certificates table
- ON DELETE SET NULL behavior
- Idempotent migration (safe to run multiple times)
Column Details:
Name: ssl_certificate_id
Type: INTEGER
Nullable: YES
Foreign Key: ssl_certificates(id)
On Delete: SET NULL
Migration Function:
add_ssl_certificate_id_to_backend_servers()
Called in run_migrations() at Line 1523
Code Cleanup:
- Removed emojis from migration logs
- Removed emojis from SSL dropdown status icons
- Changed to text: Valid, Expiring, Expired
- Changed to text: Global, Cluster
Error Fixed:
GET /api/backends - 500
column "ssl_certificate_id" does not exist
After migration runs on startup, column will exist and API will work
🐛 Bug Fix:
- Fixed SSL certificate dropdown showing empty list in Backend Server edit
- Backend Server SSL dropdown now loads certificates correctly
🔧 Technical Details:
- Wrong API endpoint: /api/ssl-certificates (incorrect)
- Correct endpoint: /api/ssl/certificates (same as Frontend)
- Added cluster_id filtering and Authorization header
- Added debug logging for troubleshooting
✅ Now Shows (Verified with Query Analysis):
- Global SSL certificates (available to all clusters)
- Cluster-specific SSL certificates for SELECTED cluster only
- Other clusters' specific SSLs are NOT shown (correct behavior)
💡 SSL Enable Logic (HAProxy Standard):
Current implementation is CORRECT per HAProxy syntax:
server name addr:port ssl [verify required]
The 'ssl' flag MUST be present before 'verify' can be used.
Therefore: SSL Enable switch → SSL dropdown (correct behavior)
Example HAProxy syntax:
✅ server es1 10.0.0.1:443 ssl verify required ca-file /path/cert.pem
❌ server es1 10.0.0.1:443 verify required (invalid - missing ssl flag)
Query Logic (Line 173-176 backend/routers/ssl.py):
Global: NOT EXISTS in ssl_certificate_clusters
Cluster-specific: scc.cluster_id = selected_cluster_id
✨ New Features:
- Added use_backend_rules validator to Frontend model
- UI now supports editing use_backend rules from Frontend Management page
- Array to string conversion for use_backend rules in edit modal
🔧 Model Improvements:
- Changed use_backend_rules field type from Optional[str] to Any (list support)
- Added parse_use_backend_rules validator (same logic as ACL/redirect rules)
- Handles 3 formats: Array, Textarea string (newline-separated), JSON string
💡 UI Improvements:
- Frontend edit modal automatically converts use_backend array to multi-line text
- Users can edit routing rules line by line in textarea
- Format: 'use_backend BackendName if condition'
✅ Complete Workflow:
1. Bulk Import: Config parsed → ACL + use_backend stored as array
2. Frontend Edit: Arrays converted to multi-line string in textarea
3. User edits ACL/use_backend rules in UI
4. Save: Textarea string → validator → array → database
5. Config Generation: Array → HAProxy config format
Example workflow:
Parse: ['use_backend API if is_api']
→ Edit UI: 'use_backend API if is_api' (textarea)
→ User edits: 'use_backend API_v2 if is_api_v2'
→ Save: ['use_backend API_v2 if is_api_v2']
→ Generate: 'use_backend API_v2 if is_api_v2' (HAProxy config)
