Remove the blue background/border container that looked disconnected
from the page. Instead highlight the Select itself with a subtle blue
border glow when no cluster is selected.

New page that provides a unified view of all IPs across all clusters.
Users can search any IP to identify which cluster/agent/backend it
belongs to, and whether it is an Agent IP, VIP (keepalive), or
Backend Server address.

asyncpg cannot infer the PostgreSQL type for $20/$21 when the Python
value is None in CASE WHEN $20 IS NOT NULL expressions. Add explicit
::text cast so asyncpg can prepare the statement regardless of whether
the agent sends keepalive data or not. This was causing ALL heartbeats
to fail with 500 error, making all agents appear offline.

- Description: constrained to 200px width, 2-line clamp with tooltip
for full text on hover. Prevents long descriptions from stretching
the table.
- Connection Type: shortened labels ("Agent"/"Sidecar" instead of
"Agent Connection"/"Sidecar Agent"), reduced column width to 110px.
- HAProxy Version: reduced width from 220px to 170px.
- Keepalive: reduced width from 180px to 155px.
- Table scroll: changed from max-content to 1100px fixed minimum,
so the table fits on normal screens without scrolling.

- ClusterManagement: show all unique VIPs from all agents (not just
first agent's VIP) to prevent misleading display in multi-agent
clusters with different virtual IPs.
- ClusterManagement: limit displayed agents to 4 with "+N more"
indicator to prevent row height explosion in large clusters.
- ClusterManagement: make keepalive IP search case-insensitive.
- Dashboard: add fetchAgentsStatus to overview tab auto-refresh
(60s interval) so keepalive state changes are reflected without
manual refresh.

- Fix DB: COALESCE(NULLIF) prevented clearing stale MASTER/BACKUP state.
Use CASE WHEN IS NOT NULL to distinguish absent fields (old agents)
from empty fields (keepalived stopped) and properly clear to NULL.
- Fix Redis: explicitly delete cache key when keepalived stops instead
of relying on 90s TTL expiry, preventing stale dashboard data.
- Fix agent scripts: SKIP_TO_DAEMON send_heartbeat now always sends
keepalive_state/keepalive_ip fields (even empty) so backend can
detect stopped keepalived and clear stale data.
- Fix legacy heartbeat endpoint: POST /{agent_id}/heartbeat now also
updates keepalive_state and keepalive_ip fields.
- UI: add horizontal scroll to ClusterManagement table to prevent
column overflow with new Keepalive column.
- UI: add VIP tooltip to Dashboard AgentStatusCard keepalive tag.
Co-authored-by: Cursor <cursoragent@cursor.com>
- Add keepalive_state and keepalive_ip columns to agents table (migration + schema)
- Add keepalive fields to AgentHeartbeat Pydantic model (backward compatible)
- Update heartbeat endpoint to persist keepalive data to DB and cache in Redis

- Update dashboard-stats agents/status API with Redis-first keepalive lookup
- Update GET /api/agents to include keepalive_state and keepalive_ip
- Show MASTER/BACKUP tag in Dashboard AgentStatusCard
- Show keepalive info in Agent Management registered agents table
- Add Keepalive column to Cluster Management table with VIP search support

Root cause: SSL update passes expiry_date as Python datetime object in
new_values. json.dumps() fails on datetime, causing save_entity_snapshot
to return {} (empty). Entity snapshot is never saved in config_version
metadata, so reject/rollback can never find it to restore old values.
Fix: Apply same JSON serialization to new_values as old_values. Only
affects SSL certificates (only entity with datetime in new_values).
All other entity types (frontend, backend, server, waf) are unaffected
as their new_values contain only JSON-serializable types.

- Timeout/INCOMPLETE logic now applies only to ssl_certificates entity type
- Non-SSL entities (frontend, backend, waf) retain original APPLYING behavior
- Remove all emoji characters from console.log and UI strings
Co-authored-by: Cursor <cursoragent@cursor.com>
- Add per-cluster SSL sync status tracking with APPLYING/SYNCED/PARTIAL states
- Add timeout detection (10min) for stalled SSL deployments showing PARTIAL status
- Add SSL-specific info in Apply Management dialog (cluster count, auto-apply notice)
- Add Deployment Status tab in SSL details showing per-cluster agent sync progress
- Implement SSL auto-reject (reject propagates to all clusters) and auto-undo
- Add conditional entity rollback for SSL reject (time-window based safety check)
- Filter REJECTED status from SSL last_config_status display
- Add pending_cluster_names to SSL list API response
- Optimize agent SSL reload: only trigger HAProxy reload when changed cert is
actually referenced in the cluster's HAProxy config (grep -qF check), preventing
unnecessary reloads on clusters that don't use the updated certificate
- Applied to all 4 SSL deploy paths: Linux/macOS standalone and daemon embedded modes

Replace the always-Active status badge with actual usage information by
querying which frontends and backend servers reference each certificate.
Backend: detail endpoint returns used_by_frontends, used_by_servers and
usage_count; list endpoint includes usage_count via scalar subqueries
checking both ssl_certificate_id and ssl_certificate_ids JSONB fields.
Frontend: General Info badge shows In Use/Not In Use, new Usage tab with
searchable frontend and server tables, summary card shows In Use count.

The detail endpoint (GET /api/ssl/certificates/{id}) was missing is_active
in its SQL SELECT/GROUP BY, causing the frontend details modal to always
show "Inactive". The list endpoint included is_active in its SQL query but
omitted it from the response dict, causing the Active counter card to
always show 0.

Root cause: After agent self-upgrade, the embedded daemon (SKIP_TO_DAEMON
block) runs instead of run_daemon(). HAPROXY_BIN and HAPROXY_CONFIG
variables were uninitialized before the daemon loop, causing SSL-triggered
HAProxy reloads to silently fail with empty path validation.
Changes:
- Initialize HAPROXY_BIN/HAPROXY_CONFIG before embedded daemon loop
- Add md5 checksum comparison in deploy_ssl_certificates() to detect
actual cert file changes (avoid unnecessary writes and reloads)
- Add check_ssl_updates() for independent SSL sync every ~2.5 min
in run_daemon(), independent of config version changes
- Add SSL-aware reload in check_config_updates(): if config validation
fails but SSL certs changed, reload HAProxy with existing config
- Add "full" fetch mode to fetch_and_deploy_ssl_certificates() to
bypass incremental timestamp filter for standalone SSL checks
Applied to both linux_install.sh and macos_install.sh.

Same pgrep self-kill bug as uninstall scripts. When user downloads
install script as install-haproxy-agent.sh, pgrep -f "haproxy-agent"
matches the installer's own bash process and kills it before
installation starts. Now filters out INSTALLER_PID and PPID.

Instead of a hardcoded PROTECTED_PATHS list (varies per environment):
- safe_rm() blocks any path not containing "haproxy-agent"
- Process killer verifies ps output contains "haproxy-agent"
- Pre/post HAProxy integrity check via md5 hash comparison of config
and service status diff (was running -> still running?)
Co-authored-by: Cursor <cursoragent@cursor.com>
pgrep -f "haproxy-agent" was matching the uninstall script's own
process (uninstall-haproxy-agent-linux.sh contains "haproxy-agent"),
causing the script to terminate itself at step 1/7 before reaching
file cleanup. Now filters out $$ (own PID) and $PPID from kill lists.

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"
CRITICAL BUG FIX:
- Previous pattern `/^defaults[[:space:]]/` required whitespace after keyword
- HAProxy allows `defaults` without a name (no trailing whitespace)
- Pattern failed to match, causing global extraction to include defaults section
New pattern uses `([[:space:]]|$)`:
- Matches keyword followed by whitespace OR end of line
- `defaults` (no name) now correctly triggers exit
- `defaults http` (named) also correctly triggers exit
Test results:
- Old pattern: extracted 8 lines (included defaults) ❌
- New pattern: extracted 4 lines (stopped at defaults) ✅
CRITICAL BUG FIX:
- Previous awk pattern allowed multiple defaults sections to be captured
- Pattern `!/^defaults/` meant "don't exit if line IS defaults"
- This caused duplicate defaults when config had listen before defaults
New pattern uses `started` flag:
- First `defaults` line: set started=1, begin capturing
- Second `defaults` line: started is set, EXIT immediately
- Any `frontend/backend/listen`: started is set, EXIT
Also includes: debug logging for validation error storage with fallback
Tested scenarios:
- Normal config (defaults → listen → frontend): ✓
- Listen before defaults: ✓
- Two defaults sections: ✓ Only first captured
- No defaults section: ✓ Empty output
- Defaults at end of file: ✓
- Empty defaults section: ✓
Bug: When haproxy.cfg has 'listen stats' BEFORE 'defaults' section,
the global extraction incorrectly included listen stats because it
only stopped at 'defaults', not at any section header.
Fix: Changed extraction to stop at ANY section (defaults/listen/frontend/backend)
This prevents duplicate listen blocks in merged config.
Root cause of 'proxy stats has same name as proxy stats' HAProxy validation error.
SECURITY FIX (agent.py):
- Ensure ONLY APPLIED versions are sent to agents
- Fixed fallback query that could return PENDING versions
- Agents will never receive unapproved configurations
UX FIX (cluster.py):
- Clear validation_error when creating new version via Apply
- Prevents stale validation errors from showing after re-apply
UX FIX (agent.py):
- Clear validation_error when agent successfully applies config
- Clear last_validation_error on agent record after success
Query agent preserved_listen_blocks dynamically and skip
conflicting entities to prevent HAProxy validation errors.
Falls back to static reserved list if no agent data available.
- /api/agents/{name}/config now returns haproxy_bin_path, haproxy_config_path, stats_socket_path from cluster
- Agent daemon uses these dynamic paths from API response for validation
- Fallback to local config file if API values not present
- Allows cluster admin to change paths without reinstalling agents
This fixes validation when HAProxy binary is in non-standard location
- Updated SUGGESTION_TEMPLATES in haproxy_error_parser.py
- Fixed fallback error messages in cluster.py
- Product language should be English throughout
Bulk Import Fix (config.py):
- Check for existing servers (including soft-deleted) before INSERT
- If server exists: UPDATE and reactivate instead of INSERT
- Create snapshot for ALL updated servers (enables reject/rollback)
- Add backend_name to UPDATE for field consistency
- Track updated/reactivated servers in response
- Prevents duplicate key constraint violation on re-import
Frontend Deletion Fix (frontend.py):
- Add hard delete support for already soft-deleted frontends
- Follows same pattern as backend.py hard delete
- Deletes WAF associations and config versions before frontend
- Works with existing orphan cleanup in Apply/Reject flows
Both fixes are safe because:
- Orphan version cleanup handles hard-deleted entities in Apply/Reject
- Consistent with existing backend.py patterns
- Snapshot-based rollback fully supported
When config content doesn't look like valid HAProxy config (missing
global/defaults/frontend/backend/listen keywords), agent now reports
this to backend via config-validation-failed endpoint.
This catches backend-side config generation errors (like Python
exceptions) that prevented actual HAProxy config from being generated.
Changes:
- Add invalid config format detection and reporting in daemon mode
- Use same curl pattern as existing HAProxy validation failure reporting
- Same endpoint, headers, error handling, and spam prevention
- Follows exact existing pattern for consistency
- Does not affect self-upgrade flow (runs before upgrade check)
Both linux and macos scripts updated identically.
Remove redundant local 'import json' statements that caused:
"cannot access local variable 'json' where it is not associated with a value"
Root cause: Local import inside try block made 'json' a local variable,
but except clause referenced json.JSONDecodeError before assignment.
Changes:
- Line 197: Remove local import, use global json (line 5)
- Line 514: Remove 'import json as _json', use global json
- Use ValueError instead of json.JSONDecodeError (equivalent, JSONDecodeError
is a subclass of ValueError)
This was causing config generation to fail completely, returning error
message as config content instead of actual HAProxy configuration.
