- Add unit tests for internal/buffer package
- Fix misleading "ring buffer" comment (it's a bounded FIFO queue)
- Remove unused BufferCapacity config field from both agents
- Rewrite flaky integration test to use polling instead of fixed sleeps
Test coverage for serviceMode, buildContainerIndex, lookupContainer,
copyStringMap, and isTaskCompletedState. 52 test cases covering service
mode detection, container index building/lookup, and task state classification.
Coverage improved from 14.7% to 17.5%.
- TestExtractPodmanMetadata: 14 test cases covering pod metadata, infra
containers, compose metadata, auto-update settings, user namespace
handling, whitespace trimming, and precedence rules
- TestDetectHostRemovedError: 11 test cases covering JSON parsing,
case-insensitive matching, error code validation, and edge cases
Coverage improved from 11.7% to 14.7% for internal/dockeragent.
- Move normalizeVersion to utils.NormalizeVersion for single source of truth
- Update agentupdate and dockeragent packages to use shared function
- Add 14 test cases for version normalization
This prevents bugs like issue #773 where a fix applied to one copy
but not the other caused an update loop.
Tests for calculateCPUPercent, calculateMemoryUsage, safeFloat,
parseTime, trimLeadingSlash, and summarizeBlockIO. 28 test cases
covering edge cases like zero deltas, cache handling, NaN/Inf,
and case-insensitive op matching.
Coverage improved from 8.0% to 11.7%.
The unified agent got the version normalization fix (1b866598), but the
standalone docker agent's checkForUpdates() still used direct string
comparison. When server returns "4.34.0" and agent has "v4.34.0", this
caused an infinite self-update loop.
Apply the same normalizeVersion() function used in the unified agent.

When systemUsage counter goes backward (common in unprivileged LXC
containers), the previous code used the absolute value as systemDelta.
This created an artificially small denominator, inflating CPU to ~100%.
Now leaves systemDelta as 0 on counter reset, falling through to the
time-based calculation which produces accurate results.

- Default enableDocker to false in UI to prevent unintended Docker
agent activation on host-only installs (Related to #766)
- Deploy agent scripts and binaries during web UI upgrades, not just
the main binary (Related to #760)
- Apply symlink resolution fix to standalone docker agent self-update
to prevent cross-device rename failures (Related to #737)
Mark intentionally unused parameters with underscore to:
- Silence unparam warnings for legitimate unused parameters
- Keep function signatures intact for API compatibility
- Remove unused req from serveChecksum helper
- Use container.Summary instead of types.Container
- Use swarmtypes.ServiceListOptions instead of types.ServiceListOptions
- Use swarmtypes.TaskListOptions instead of types.TaskListOptions
These types were deprecated in favor of package-specific types.
Podman can return unstable or empty daemon IDs across API calls. When
the agent fetched info.ID on every report cycle, this could cause the
agent identity to change mid-session, triggering "token already in use"
errors on the server.
Cache the daemon ID at initialization and use it consistently for all
reports.

Issues found during scenario testing:
1. Version propagation: The hostagent and dockeragent packages were
reporting their own Version (0.1.0-dev) instead of the unified
agent's version. Added AgentVersion config field to pass the
parent's version down.
2. macOS legacy cleanup: The install.sh script was missing cleanup
for pulse-docker-agent on macOS.
3. Windows legacy cleanup: The install.ps1 script was missing cleanup
for legacy PulseHostAgent and PulseDockerAgent services.
These fixes ensure:
- Unified agent reports consistent version across host/docker metrics
- Legacy agents are properly removed on all platforms during upgrade
- Users migrating from legacy agents get a clean transition
Add seamless migration path from legacy agents to unified agent:
- Add AgentType field to report payloads (unified vs legacy detection)
- Update server to detect legacy agents by type instead of version
- Add UI banner showing upgrade command when legacy agents are detected
- Add deprecation notice to install-host-agent.ps1
- Create install-docker-agent.sh stub that redirects to unified installer
Legacy agents (pulse-host-agent, pulse-docker-agent) now show a "Legacy"
badge in the UI with a one-click copy command to upgrade to the unified
agent.
Addresses the root cause of issue #631 (infinite Docker agent restart loop)
and prevents similar issues with host-agent and sensor-proxy.
Changes:
- Set dockeragent.Version default to "dev" instead of hardcoded version
- Add version embedding to server build in Dockerfile
- Add version embedding to host-agent builds (all platforms)
- Add version embedding to sensor-proxy builds (all platforms)
This ensures:
1. Server's /api/agent/version endpoint returns correct v4.26.0
2. Downloaded agent binaries have matching embedded versions
3. Dev builds skip auto-update (Version="dev")
4. No version mismatch triggers infinite restart loops

## Samsung SSD Fix (#547)
Samsung 980 and 990 series SSDs have known firmware bugs that cause them to
report incorrect health status (typically FAILED or critical warnings) even
when the drives are actually healthy. This is commonly due to incorrect
temperature threshold reporting in the firmware.
This change adds special handling to detect these drives and skip health
status alerts while still monitoring wearout metrics, which remain reliable.
The fix also clears any existing false alerts for these drives.
Users experiencing these false alerts should update their Samsung SSD firmware
to the latest version from Samsung, which typically resolves the issue.
## Docker Agent CPU Fix (#622)
Addresses issue where Docker container CPU usage shows 0%. The Docker
agent uses ContainerStatsOneShot which typically doesn't populate
PreCPUStats, requiring manual delta tracking between collection cycles.
Changes:
- Fix logic bug where prevContainerCPU was updated before checking if
previous sample existed, causing incorrect delta calculations
- Add comprehensive debug logging showing which calculation method
succeeded (PreCPUStats, system delta, or time-based fallback)
- Add warning after 10 PreCPUStats failures to inform about manual
tracking mode (normal for one-shot stats)
- Add detailed failure logging when CPU calculation cannot complete
Expected behavior: First collection cycle returns 0% (no previous
sample), subsequent cycles show accurate CPU metrics.
This commit addresses multiple issues in the Docker/host agent removal flow:
Agent Stop Fix:
- Add systemctl stop command after agent acknowledgement to prevent systemd restart
- Previous behavior: agent disabled but systemd immediately restarted it (Restart=always)
- New behavior: agent disables itself, sends ack, then stops systemd service completely
UX Improvements:
- Add real-time elapsed time counter during removal wait
- Show progress indicators prominently (no longer hidden in dropdown)
- Display expected time range (30-60 seconds) and last heartbeat
- Auto-show timeout warning after 2 minutes with actionable "Force remove" button
- Add contextual help explaining what's happening at each stage
Security Enhancement:
- Automatically revoke API tokens when removing Docker/host agents
- Previous behavior: tokens remained valid after agent removal
- New behavior: tokens are revoked and persisted immediately on removal
- Prevents removed agents from re-authenticating with old credentials
Extends Docker container monitoring with comprehensive disk and storage information:
- Writable layer size and root filesystem usage displayed in new Disk column
- Block I/O statistics (read/write bytes totals) shown in container drawer
- Mount metadata including type, source, destination, mode, and driver details
- Configurable via --collect-disk flag (enabled by default, can be disabled for large fleets)
Also fixes config watcher to consistently use production auth config path instead of following PULSE_DATA_DIR when in mock mode.
