Move guest threshold resolution and filter evaluation logic from
alerts.go to filter_evaluation.go for better code organization.
Extracted functions:
- evaluateFilterCondition
- evaluateVMCondition
- evaluateContainerCondition
- evaluateFilterStack
- getGuestThresholds
This reduces alerts.go by ~370 lines and isolates the rule evaluation
engine that determines which thresholds apply to guests.
Cover API validation functions that were previously untested:
- validateIPAddress: IPv4/IPv6 validation with edge cases
- validatePort: Port range validation (1-65535)
- defaultPortForNodeType: Proxmox node type to default port mapping
This function was superseded by HandleTestNode which is wired to the
router at /api/config/nodes/{id}/test. The old function was not
registered in the router and served no purpose.
Removes 121 lines of unused code.
The host-agent's isCPUChip function was missing rp1_adc (Raspberry Pi RP1 ADC),
which is already detected in the monitoring package. This sync ensures consistent
CPU temperature chip detection across both code paths.
Tests added by ADA run #97 but commit was missed.
Covers: RaidZ types, log/cache/spare devices, nested mirrors,
ConvertToModelZFSPool, and struct field tests.
The VERSION variable was hardcoded to v4.32.0 instead of being empty,
which prevented the "fetch latest release" logic from running. When
VERSION is empty, REQUESTED_VERSION defaults to "latest" which triggers
proper release detection via GitHub API.

Tests for annotateResolvedMetadata, resolveAppriseNotificationType,
normalizeQueueType, and resolvedTimeFromAlerts (44 test cases).
Coverage 38.0% → 39.0%.
Add comprehensive tests for the cloneProfile and clonePhase utility
functions in pkg/discovery/discovery.go. Tests verify deep copying
behavior for all fields including subnets, metadata, warnings, extra
targets, and phases to ensure mutations don't affect original objects.
Add 56 test cases covering:
- isTransientError: 13 cases for context errors, retryable MonitorErrors,
and standard error types (nil, Canceled, DeadlineExceeded, Timeout, etc.)
- shouldTryPortlessFallback: 14 cases for connection error patterns that
trigger port fallback (refused, reset, no such host, timeout variants)
- shouldAttemptFallback: 13 cases for timeout/deadline/canceled patterns
used in storage polling fallback
- classifyDLQReason: 8 cases for dead letter queue reason classification
(max_retry_attempts vs permanent_failure)
- Edge cases: 3 cases for overlapping error patterns and partial matches
First test file for these error classification utilities used in retry
and fallback decision logic.
52 test cases covering:
- firstValueForKeys: 18 cases for multi-key lookup with priority ordering
- hasAnyKey: 15 cases for key existence checking
- discoveryConfigMap: 19 cases for nested config extraction with camelCase/snake_case support
Tests verify edge cases including nil maps, empty key slices, type assertion failures,
and priority ordering for field name variants used in configuration parsing.
Add 97 test cases for four utility functions in monitor.go:
- stringValue (30 cases): Type-to-string conversion for various Go types
including string, int types, float types, json.Number, fmt.Stringer
- anyToInt64 (34 cases): Interface-to-int64 conversion with overflow
handling, string parsing, and json.Number support
- parseInterfaceStat (15 cases): Interface stat map parsing for network
interface statistics
- extractGuestOSInfo (18 cases): QEMU guest agent OS info extraction
with fallback logic for various Linux distros, Windows, FreeBSD
Coverage for these functions: 0% → 100%
Package coverage: 37.5% → 38.5%
Added comprehensive tests for 6 previously untested pure utility functions:
- sortContent: sorts comma-separated storage content values
- formatSeconds: converts total seconds to HH:MM:SS format
- dedupeStringsPreserveOrder: deduplicates strings while preserving order
- sanitizeGuestAddressStrings: validates and filters IP addresses
- copyFloatPointer: creates independent copy of float64 pointer
- clampInterval: clamps time.Duration to specified bounds
Tests cover edge cases including empty inputs, boundary conditions,
special values (DHCP, loopback addresses), and various separators.
Coverage increased from 36.8% to 37.5%.
Test coverage for error detection and retry logic:
- extractStatusCode: 13 test cases for HTTP status code extraction
- isTransientRateLimitError: 17 test cases for rate limit detection
- isNotImplementedError: 14 test cases for 501 error detection
- isVMSpecificError: 16 test cases for VM-scoped errors
- calculateRateLimitBackoff: backoff timing verification
- isAuthError: 12 test cases for authentication errors
Coverage 35.5% → 37.3%
The StackedMemoryBar component was using flex layout for segments,
but flex children grow by default regardless of percentage width.
Changed to absolute positioning (like MetricBar uses) so the width
percentages actually work as expected.

Coverage for sessionHash, CreateSession, ValidateSession,
ValidateAndExtendSession, DeleteSession, persistence, and cleanup.
21 test cases covering session lifecycle, expiration handling,
and disk persistence. Coverage 25.0% → 25.3%.
Tests for detectProxy, isConnectionSecure, getCookieSettings, and
generateSessionToken functions. Covers proxy detection for various
headers including X-Forwarded-For, CF-Ray, Forwarded (RFC 7239),
and secure connection detection via TLS and proxy headers.
32 test cases covering makeNodeSnapshotKey and makeGuestSnapshotKey
utility functions used for diagnostic memory snapshot storage. Tests
cover simple inputs, edge cases (empty strings, negative VMIDs),
special characters, and key uniqueness verification. Also includes
struct field tests for NodeMemoryRaw and VMMemoryRaw.
First test file for diagnostic_snapshots.go. Coverage 36.7% → 36.8%.
The backup status indicator feature was incomplete - it added the UI
component but never populated VM/Container LastBackup from actual
backup data. Now SyncGuestBackupTimes() is called after storage
backups and PBS backups are polled, matching each guest's VMID to
its most recent backup timestamp.
Fixes#786
Add transient empty payload protection for hosts data, matching the
existing protection for dockerHosts. When a websocket message contains
an empty hosts array (transient state), the UI now waits for 3
consecutive empty payloads before applying the change.
This prevents the "Host" type badge from disappearing intermittently
in Settings → Agents → Managed Agents when the unified agent is
reporting both host and docker data.

24 test cases covering transaction lifecycle: staging, commit, rollback, and cleanup.
Tests include atomic commit behavior, backup/restore on failure, directory creation,
permission handling, and idempotent cleanup.
First test file for import_transaction.go. Coverage 42.4% → 42.7%.
When running install-sensor-proxy.sh on multiple nodes in a cluster, each
installation was removing all existing pulse-managed-key entries before
adding its own. This caused the following scenario:
1. Run script on node A: node A's key is added to all nodes
2. Run script on node B: node B's key replaces node A's key on all nodes
3. Result: node A's proxy can no longer SSH to other nodes
The fix changes the behavior to:
- Check if the specific SSH key already exists on the target
- Only add the key if not present (idempotent)
- Never remove existing pulse-managed-key entries
This allows multiple sensor-proxy installations to coexist in a cluster,
with each node's proxy key authorized on all nodes.

22 test cases covering CRUD operations (Get, GetAll, Set, Delete,
ReplaceAll), persistence (Load, save with atomic write, directory
creation), legacy ID migration (GetWithLegacyMigration for clustered
and standalone formats), round-trip verification, and concurrency.
First test file for guest_metadata.go, complementing the similar
docker_metadata_test.go added in previous run.
When multiple cluster nodes register sensor-proxy, each registration
was overwriting the previous node's control token on the shared
PVEInstance. This caused "Proxy token not recognized" errors on all
but the last-registered node.
Changes:
- Add TemperatureProxyControlToken field to ClusterEndpoint struct
- Store control tokens per-endpoint for cluster registrations
- Check both instance-level and endpoint-level tokens when validating

Add 42 test cases for security-critical validation utility functions:
- TestStripNodeDelimiters (10 cases): IPv6 bracket handling, edge cases
- TestParseNodeIP (10 cases): IPv4/IPv6 parsing with bracket support
- TestNormalizeAllowlistEntry (11 cases): case normalization, whitespace
handling, IPv6 full form compression
- TestIPAllowed (11 cases): CIDR matching, hosts map lookup, nil handling
These functions are used for node allowlist validation to prevent SSRF
attacks in the sensor proxy.
