Prepares 3.8.0. It needed #708 (the removal of the 35 APIs deprecated for 3.8.0), which is now merged; this PR is on main.

scripts/check_release_version.py v3.8.0 reports that the tag, src.__version__ and the CHANGELOG agree. test_version_consistency.py passes.

After merging:

  1. Tag v3.8.0 on the merge commit. Devices on the new stable channel follow release tags.
  2. In ledmatrix-plugins, change the guard table's None entries in scripts/check_min_core_version.py to "3.8.0" (every core module added since 3.7.0, including stage 4's). Its test checks entries against real tags, so this has to follow the tag.
  3. The plugin updates merged today (live scoreboard cards, flights glide, weather radar) require 3.8.0. Devices get them once they run 3.8.0.

ChuckBuilds and others added 4 commits October 1, 2026 09:47
The usage scan (docs/DEPRECATIONS_3.8.md, regenerated 2026-10-01 and
committed here) finds no call or override of any of them in the 46
monorepo plugins or the 8 third-party plugins plugins.json lists; the
only core callers were other deprecated methods removed alongside.

- CacheManager: 13 methods, plus the private helpers only
  has_data_changed used (_has_*_changed, _is_market_open).
- DisplayManager: 7 methods, plus WEATHER_COLORS and the private
  _draw_sun/_cloud/_rain/_snow/_storm helpers only the icon methods used.
- FontManager: 14 methods, plus size_tokens, _save_overrides and
  _clear_plugin_font_cache. font_overrides and _load_overrides stay:
  resolve_font() still applies config/font_overrides.json.
  performance_stats stays: get_font() keeps it and tests read it.
- PluginManager.get_enabled_plugins.

test_deprecation.py pins only the two 3.9.0 markers now; the scanner
tests run against a stand-in core instead of the real markers. The
memory-tier tests read stats through log_memory_cache_stats() and the
component, and the test of the removed _clear_plugin_font_cache goes.
Docs drop the removed methods' reference entries; the Deprecated APIs
table becomes "Removed in 3.8.0". CHANGELOG gains a Removed section.

…n methods

VisualTestDisplayManager still drew weather icons that DisplayManager no
longer has, so a plugin's visual tests could pass on calls that raise
AttributeError on the real display. Its draw_sun/draw_cloud/draw_rain/
draw_snow/draw_weather_icon/draw_text_with_icons, WEATHER_COLORS and the
private helpers go, with the tests that exercised them. The CHANGELOG's
Deprecations entries no longer say nothing is removed.

Bumps src.__version__ to 3.8.0 and turns Unreleased into ## 3.8.0, with a
summary and a New modules list (vegas_elements, testing.vegas, sports_vegas;
display_watchdog, plugin_catalog, plugin_runtime) for plugins flooring on
3.8.0. Adds the CHANGELOG line #701's second commit lacked (blocks laid out
off the render thread).

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~25 minutes

Change: Other

Merge Risk: 🔵 Low · up to 8ab08

Unloading a plugin can leave its font registrations and cache entries in memory. Impact is small, but the cleanup should be restored before merge or accepted as a known gap. The rest of the release is consistent.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 8ab08

The release deliberately removes obsolete plugin APIs, and the published scan found no users among the checked plugins. No newly introduced security attack path was established. Remaining uncertainty concerns unscanned integrations and plugin-font cleanup during unload, failure, and reload.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — The examined font path operates on shared in-process manifests, catalogs, and cached font identities. Its initiating input is a plugin manifest supplied through plugin loading. The evidence does not establish a newly exposed remote entrypoint or tenant-wide, service-wide, or environment-wide impact.

Trust Boundaries and Controls

  • observed — Plugin font definitions can select HTTP(S), plugin-relative, or other filesystem sources. Catalog insertion uses plugin_id::family, and ordinary resolution uses the matching plugin catalog for bare family names. This namespacing reduces accidental identity collisions; it is not evidence of authorization isolation, since already-qualified families proceed to get_font().

Resilience and Maintainability Implications

  • inferred — Unload and failed-load cleanup remove manager font-usage records but do not remove plugin manifests, global catalog entries, or cached font identities. Re-registration replaces the plugin-specific catalog without explicitly clearing old global entries. The supplied summaries indicate these retained paths are unchanged, and the usage inventory reports the removed unregistration API unused. State retention therefore appears to predate this release; newly worsened exposure through external cleanup callers was not established.

Hardening Proposals

  • proposed — Consider a core-owned, idempotent plugin-font teardown covering manifests, catalogs, and cached identities on unload, failed load, and replacement. Validate partial registration, repeated reload, and interruption or concurrency during teardown. This would address the existing ownership limitation rather than remediate a verified PR-introduced vulnerability.

#703, #705, #706 and #693 merged after this branch was cut; their CHANGELOG
entries now sit under 3.8.0. The summary and New modules list name them
(sports consolidation stage 4's four modules, src/ipc, field_model), stage
4's section says to floor on 3.8.0, and src/common/README.md marks its four
modules 3.8.0 instead of Unreleased.

* fix(fonts): unloading a plugin forgets its manifest fonts

PluginManager.unload_plugin() and the failed-load cleanup only called
FontManager.forget_manager_fonts(), which drops usage data. The plugin's
manifest registrations stayed: plugin_fonts / plugin_font_catalogs, its
plugin_id::family entries in font_catalog, and cached font objects for them
-- so its fonts kept resolving after unload and a family a reinstalled
manifest dropped stayed registered. The deprecated unregister_plugin_fonts
did this cleanup but nothing called it; it was removed in #708.

Add FontManager.forget_plugin_fonts(plugin_id) and call it from both
paths alongside forget_manager_fonts (each guarded on its own, so a font
manager stub with only one still works). FontManager takes no locks, so
like forget_manager_fonts it uses atomic pops over snapshots. A reload
(unload + load) registers the manifest fonts again and they resolve.

Raised by CodeRabbit on #709.

…huckBuilds#581)

* feat(web): weekly automatic updates with health check and rollback

A General-tab toggle (off by default) checks for and installs LEDMatrix and
plugin updates once a week, overnight in the configured timezone.

- Pre-update checks skip (and report) instead of forcing: local edits or
  commits, merge/live rebase, no upstream, low disk, missing health check, or
  a version that was already rolled back. An abandoned rebase (HEAD back on a
  branch) is cleared, since it would otherwise block every pull.
- The pull reuses the Update Code path (now perform_core_update(), which
  reports dependency install failures as data).
- ledmatrix-update-verify.service, started via a .path unit from a request
  file, restarts the services from its own cgroup, requires them to come up
  and stay up, and otherwise resets to the previous commit and reinstalls the
  previous requirements. It runs a copy of the checker taken before the pull.
- No SSH needed: switching the toggle on restarts the display service, which
  (as root) installs the two units from the repo templates for the web user.
  first_time_install.sh installs them too and takes --enable-auto-update /
  LEDMATRIX_AUTO_UPDATE (passed through by one-shot-install.sh).
- Plugins update after the code passes its check; failures, blocks and
  rollbacks raise an Overview banner and show under the toggle.

Tested end to end on a Pi: web-UI setup, a good update, a broken web service
and a broken display (both rolled back), a blocked local edit, and an
abandoned rebase found on the device.

* chore(auto-update): address static-analysis findings

- Replace the subprocess.CompletedProcess the verifier fabricated for a
  command that could not start with a plain namedtuple; nothing is executed
  there, but the scanner flags any CompletedProcess built from variables.
- Mark the subprocess imports with the repo's standard B404 annotation (all
  calls are list-form argv, no shell).
- Mark the rollback-failed message as not SQL (B608 matched its wording).

* fix(auto-update): CI failures on Linux

- Keep the setup result when chown fails. CI runs as a non-root user, where
  chown to the web user raises; that discarded the result file, so the
  General tab would never learn whether setup worked. Regression test added.
- Register the two new /api/v3/system/auto-update routes in the URL map
  snapshot.
- Use utility classes app.css defines (space-y-1, hover:text-red-600).

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* fix(auto-update): address review feedback

- Health check: a failed restart command no longer lets the check run
  against the still-running old process; it counts as a failure (and after a
  rollback, as a failed rollback). An unreadable restart count is never
  treated as stable, since a crash loop looks healthy between attempts.
- Installer writes the auto_update setting to a temp file and swaps it in,
  keeping mode and owner, so a running config watcher never reads a
  truncated config.json.
- Verify unit quotes its command-line paths (install folders with spaces);
  setup refuses folder names systemd would reinterpret (%, quotes,
  backslashes, control characters) and says so on the General tab.
- The auto-update status route no longer returns exception text.

* fix(auto-update): keep error detail in the status route's 500

test_web_error_detail requires every 5xx handler to log the traceback and
return describe_exception(e), which redacts credentials, so failures are
diagnosable from the web UI. Dropping it for CodeQL broke that policy.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* fix(auto-update): dismiss route rejects non-object JSON with 400

A JSON array or scalar body made `.get('alert_id')` raise, returning 500.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* fix(auto-update): let the app-wide handler answer status-route errors

CodeQL (py/stack-trace-exposure, ChuckBuilds#709) flagged the route's own except,
which returned describe_exception(e). web_interface/app.py's error handler
already logs the traceback and returns the same redacted detail for any
unhandled exception, so the local copy is removed: same response, no new
exception-to-response flow, and test_web_error_detail's policy still holds.
