📝 Walkthrough

Walkthrough

The pull request adds scheduled process-resource history, history queries and retention, process metrics in health responses, and a System Info performance view. It moves database status details to Storage, updates PRD-writing guidance, and narrows an initialization-panel CSS selector.

Changes

Resource History and Performance View

Layer / File(s) Summary
Resource-history storage and tick sampling
server/db/schema/app.sql, server/db/db_upgrade.py, server/database.py, server/scan/resource_history.py, server/__main__.py, server/plugins/maintenance/config.json, test/scan/test_resource_history.py
Adds the Resource_History table and index. Scheduled ticks can record CPU, RSS, I/O, duration, and failure status. The maintenance setting controls collection, and tests cover sampling and tick integration.
History queries and retention
server/const.py, server/api.py, server/plugins/db_cleanup/script.py, server/plugins/maintenance/README.md, test/db/test_resource_history_rollup.py, test/db/test_db_cleanup.py
Adds raw and bucketed history queries and exposes four resource-history data sources through the existing API flow. Cleanup deletes expired history rows. Tests cover rollups and retention.
Process metrics in health responses
server/api_server/health_endpoint.py, server/api_server/openapi/schemas.py, server/api_server/api_server_start.py, test/server/test_health_endpoint_process.py
Adds process CPU percentage and RSS to health status and the response schema. Tests cover values, error fallbacks, and response fields.
System Info performance view
front/systeminfo.php, front/systeminfoPerformance.php, front/systeminfoStorage.php, front/js/graph_resource_history.js, front/js/common.js, front/php/templates/header.php, front/php/templates/skel_tab_sysinfo_performance.php, front/php/templates/language/*, front/maintenance.php, docs/PERFORMANCE.md
Adds the Performance tab, range controls, charts, and loading placeholders. Moves database status details from Maintenance to Storage. Adds performance documentation and translation entries.

PRD-Writing Guidance

Layer / File(s) Summary
API exposure and performance analysis
.claude/skills/prd-writing/SKILL.md, .gemini/skills/prd-writing/SKILL.md, .github/skills/prd-writing/SKILL.md
Adds API-exposure decisions and performance-analysis checks. Updates the performance-impact step reference.
Final review and reusable findings
.claude/skills/prd-writing/SKILL.md, .gemini/skills/prd-writing/SKILL.md, .github/skills/prd-writing/SKILL.md
Expands final checks and adds guidance to document review corrections and consider whether implementation findings generalize.

Initialization Panel Styling

Layer / File(s) Summary
Restrict initialization panel styling
front/css/app.css
The initialization check panel CSS rule now requires the active class.

Priority: ➖ Normal

Change: Feature

Merge Risk: 🔵 Low · up to 0d600

A database query failure can interrupt the Storage tab, and a malformed performance-retention setting can skip scheduled cleanup. Both failures are bounded and have straightforward fixes, but should be addressed before merging.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to 0d600

A malformed new retention setting can stop scheduled database cleanup, including cleanup of other records. Resource-history files can also outlive the database rows they represent until they are refreshed. Normal settings and existing access controls reduce the risk, but the retention behavior needs review.

Retained concerns

  • Medium · security · inferred: An invalid value for the new MAINT_PERF_DAYS setting disables optional sampling safely but can raise before the scheduled cleanup subprocess begins. That can strand retention of Resource_History and the other tables cleaned by the same run.
  • Low · security · inferred: Deleting retained history from the database does not invalidate an already captured or published JSON snapshot. Depending on cleanup and refresh ordering, the browser-facing file may continue to expose rows after the database retention cutoff until a newer snapshot replaces it.
Security review details

Security Blast Radius

  • inferred — The added history files make process and scan-performance telemetry available to callers admitted by the existing JSON endpoint. If web protection is disabled, that endpoint has no demonstrated identity gate. Tenant-specific exposure and deployment-level controls are unknown.

Security Findings and Attack Paths

  • inferred — A malformed new retention value can interrupt the shared cleanup run, extending the lifetime of records it would otherwise delete. This is a conditional retention failure, not evidence that an attacker can change the setting.

Trust Boundaries and Controls

  • observed — The chart's normal request names a resource-history file, but a direct caller controls the endpoint's file parameter. Basename normalization limits traversal; enabled web protection checks a session or configured bearer token. Neither control restricts the caller to the chart's file names.

Resilience and Maintainability Implications

  • inferred — Database deletion and file publication are separate transitions. A captured snapshot can remain readable after cleanup, and a reader can encounter a file during its direct write; the latter write behavior predates this PR but now also applies to resource history.

Hardening Proposals

  • proposed — Validate the retention value before either consumer uses it, keep failure of optional history settings from stopping unrelated cleanup, and coordinate snapshot expiry or refresh with database retention.

Review comments at @front/js/graph_resource_history.js:
- Around line 22-72: Update initResourceHistoryGraphs to assign each request a
monotonically increasing identifier and check it at the start of the success
callback; return before changing charts or the disabled message if a newer
request has started.

Review comments at @front/systeminfoStorage.php:
- Around line 26-33: Update the database-opening flow around `$db_info_conn` to
check that `$nax_db` is a readable file before opening it, and open it with
`SQLITE3_OPEN_READONLY` so a missing database is never created. Handle SQLite
open or query exceptions so failures leave the Storage tab available, while
preserving the existing table-size display when the database is accessible.

Review comments at @server/__main__.py:
- Line 159: Parse the MAINT_PERF_DAYS setting defensively where
resource_history_enabled is assigned so empty or non-numeric values disable
optional resource history instead of raising and stopping the main loop; handle
TypeError and ValueError without changing valid-value behavior.

Review comments at @server/plugins/db_cleanup/script.py:
- Line 120: Update the retention cutoff in the `sql` statement to use
`datetime()` instead of `date()`, matching the timestamp precision of
`resDateTime` and the read queries. Convert `MAINT_PERF_DAYS` to an integer when
building the cutoff.

Review comments at @server/scan/resource_history.py:
- Around line 82-84: Read and calculate RSS before the database insert
error-handling block, and handle psutil sampling failures independently by using
the sampler’s zero fallback; then pass the resulting value into the insert so
sampling errors do not skip the row or get logged as insert failures.

🟡 Minor · Guard the MAINT_PERF_DAYS conversion in the cleanup plugin. · script.py:39

server/plugins/db_cleanup/script.py:39
🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Guard the MAINT_PERF_DAYS conversion in the cleanup plugin.

An empty or nonnumeric MAINT_PERF_DAYS value raises before cleanup_database() runs. The scheduled tick handles this error only for its resource-history gate. The separately launched DBCLNP process remains unguarded, so scheduled cleanup can be skipped.

Suggested fix
-    MAINT_PERF_DAYS = int(get_setting_value("MAINT_PERF_DAYS", 30))
+    try:
+        MAINT_PERF_DAYS = int(get_setting_value("MAINT_PERF_DAYS", 30))
+    except (TypeError, ValueError):
+        MAINT_PERF_DAYS = 30

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Handle a failed table-list query before calling fetchArray.

If SQLite cannot read the table list, SQLite3::query() can return false. Line 33 then throws an Error, which the catch (Exception $e) block does not catch. The Storage tab fails instead of showing its other storage information. Check the query result before the loop, and keep the failure within the database-status fallback. (php.net)
