# DigiServer v2 — Code Sanitization Review **Generated:** 2026-09-10 **Snapshot:** `docs/legacy code/` (1.7 MB, 171 files, 49 Python files) — full restore point. Analysed **42 Python files / 240 functions / 104 routes / 32 templates** under `app/` and `migrations/`. > Review each section below and reply with the IDs you want deleted (e.g. `A1, A2, B1`). > Nothing is deleted until you confirm. Everything is recoverable from `docs/legacy code/`. --- ## ✅ Status — Applied 2026-09-10 **Removed (A1, A2, D1, D2):** | ID | Removed | Notes | |---|---|---| | A1 | `app/blueprints/content_old.py` | + 3 templates orphaned by its removal | | A2 | `app/utils/nginx_config_reader.py` | | | D1 | 5 group functions + their `__init__.py` exports | `get_player_status_info` kept (live) | | D2 | `app/models/group.py`, `Content.groups`, `Content.group_count` | | **Extra cleanup triggered by A1/D2:** - Deleted orphaned templates: `upload_content.html` (278), `edit_content.html` (11) - Removed the dead `groups` key from `/api/system-info` and `group_count` from `/api/content` - Removed the `'group_id': getattr(player, 'group_id', None)` compat shim from `/api/player-status` - Updated 8 documentation files **Also removed (B1, B2) — applied in a second pass:** | ID | Removed | Notes | |---|---|---| | B1 | `app/blueprints/playlist.py` (310 LOC) + its registration in `app.py` | Whole legacy blueprint; its only real route redirected to `content.manage_playlist_content` | | B2 | 3 routes in `players.py`: `reorder_content`, `reorder_playlist`, `remove_from_playlist` (~103 LOC) | Two queried nonexistent columns (`Content.player_id`, `Content.position`, `Player.playlist_version`) → guaranteed 500s | **Extra cleanup triggered by B1:** - Deleted `content_list.html` (202 lines) — its only remaining reference was `url_for('playlist.manage_playlist')`. It was **already orphaned** (no Python file rendered it) after `content_old.py` was deleted, so it has been removed for real this time. - Deleted `players/player_page.html` (227 lines) — it was **never rendered** by any view (the `players.player_page` route redirects to `manage_player`), so it was dead UI. Corrects the earlier "false positive" note below. > ⚠️ **Functional note:** `players.regenerate_auth_code` (`POST /players//regenerate-auth`) is now > referenced by **no template** — `player_page.html` was its only caller. The endpoint still works if > invoked directly. The equivalent control lives in `manage_player.html` via the quickconnect flow. > Restore `player_page.html` from `docs/legacy code/` if you want that button back. **Result (A + B + D combined):** ``` 42 → 38 Python modules 9,311 → 8,296 LOC 104 → 82 routes 32 → 28 templates 7 → 6 blueprints dead modules: 2 → 0, orphan templates: 0 ``` **Verified:** all files compile; smoke test passes on a fresh DB (every API endpoint + key UI route returns < 500); `db.metadata` no longer registers `group`/`group_content`; app boots against a migrated copy of the real `dashboard.db` with all data intact; `app.blueprints` no longer contains `playlist`. > ⚠️ **Still open:** the real `data/instance/dashboard.db` predates the `original_filename` migration. > On startup the entrypoint now applies it automatically. To fix locally, run: > ``` > DATABASE_URL=sqlite:///$PWD/data/instance/dashboard.db ./.venv/bin/python migrations/add_original_filename_to_content.py > ``` --- ## Section A — Dead modules (zero importers) | ID | Target | LOC | Evidence | Risk | |---|---|---|---|---| | **A1** | `app/blueprints/content_old.py` | 500 | `app.py` imports `content.py`; this file's `content_bp` is **never registered**. Superseded "old" content workflow. | **Low** | | **A2** | `app/utils/nginx_config_reader.py` | 120 | Never imported anywhere. Stack migrated nginx → Caddy, so the reader is obsolete. | **Low** | ```mermaid graph LR app_py["app.py

Only the `content.*` versions were wired to the UI; the legacy ones had no template references. | ID | Target | LOC | Evidence | Risk | |---|---|---|---|---| | **B1** ✅ | `app/blueprints/playlist.py` (whole file + registration) | 310 | Entire file was legacy per-player playlist. Its `manage_playlist` route did nothing but **redirect** to the modern `content.manage_playlist_content`. The other 6 routes had **no template reference**. | **Low–Med** | | **B2** ✅ | 3 routes in `players.py`: `reorder_content`, `reorder_playlist`, `remove_from_playlist` | ~103 | Superseded by `content.*`. Two queried nonexistent columns (`Content.player_id`, `.position`, `Player.playlist_version`) → guaranteed HTTP 500 if called. | **Low** | **Duplicate operation matrix** | Operation | Modern (LIVE) | Legacy (DEAD) | |---|---|---| | Add content | `content.add_content_to_playlist` | `playlist.add_to_playlist` | | Remove content | `content.remove_content_from_playlist` | `playlist.remove_from_playlist`, `players.remove_from_playlist` ⚠️broken | | Reorder | `content.reorder_playlist_content` | `playlist.reorder_playlist`, `players.reorder_content` ⚠️broken, `players.reorder_playlist` ⚠️broken | | Set duration | `content.update_playlist_content_duration` | `playlist.update_duration` | | Mute audio | `content.update_playlist_content_muted` | `playlist.update_muted` | | Toggle edit | `content.update_playlist_content_edit_enabled` | — | | Clear | — | `playlist.clear_playlist` | --- ## Section C — Broken code: references to columns that do not exist Confirmed against the live DB schema. These raised `AttributeError`/`OperationalError` at runtime. **All resolved by deleting A1 + B2.** | ID | Location | Broken reference | Reachable? | |---|---|---|---| | **C1** ✅ | `players.py:768,775` (`remove_from_playlist`) | `player.playlist_version` | Via route only (no UI link) | | **C2** ✅ | `players.py:~700` (`reorder_playlist`) | `Content.player_id`, `Content.position` | Via route only (no UI link) | | **C3** | `content_old.py:189-190` | `player.playlist_version` | No (dead module) | | **C4** | `content_old.py:50,57` | `content.player_id`, `player.group` | No (dead module) | > ✅ **Resolved by deleting A1 + B2.** If you keep those files, they must be rewritten. **Not a bug (verified by hand):** `Content._playlist_duration` / `._playlist_position` / `._playlist_muted` in `api.py` are set **dynamically** by `Playlist.get_content_ordered()`. These are intentional and work correctly — the static analyzer flags them because it only sees model class attributes. --- ## Section D — Legacy groups subsystem Groups are fully deprecated (0 rows, `/api/groups` already commented out), but the code lingers. | ID | Target | LOC | Evidence | Risk | |---|---|---|---|---| | **D1** | 5 group functions in `app/utils/group_player_management.py`: `get_group_statistics`, `assign_player_to_group`, `bulk_assign_players_to_group`, `get_online_players_count`, `get_players_by_status` + their `__init__.py` exports | ~130 | **Zero callers outside the module.** All three group functions reference `player.group_id`, **which does not exist** → broken. | **Low** | | **D2** | `app/models/group.py` (Group model + `group_content` table) | 71 | Retained only because `Content.groups` FK relationship and `Content.group_count` reference it. Requires touching the Content model. | **Medium** | > ⚠️ **Keep:** `get_player_status_info()` (top of the same file) is **live** — used at > `players.py:28` and `players.py:432`. Only the group functions should go. --- ## Section E — Legacy redirect stubs Thin compatibility shims that only redirect to the modern UI. They're harmless but keep dead URL surface alive. | ID | Target | Evidence | |---|---|---| | **E1** | `players.player_page` (`/players/`) | Body is a single `redirect(url_for('players.manage_player'))`. Still `url_for`-referenced by 2 templates, so keeping it is fine. | | **E2** | `playlist.manage_playlist` (`/playlist/`) | Part of B1 — already covered by deleting that file. | --- ## Section F — Orphan templates / assets | ID | Target | LOC | Evidence | |---|---|---|---| | — | (none) | — | After the B1/B2 pass the codebase has **0 orphan templates**. | --- ## Recommended batches — ✅ **ALL APPLIED** | Batch | Contents | Total removed | Status | |---|---|---|---| | **Batch 1 — Safe clean** | **A1, A2** | ~620 LOC | ✅ done | | **Batch 2 — Legacy playlist** | **B1, B2** | ~413 LOC | ✅ done | | **Batch 3 — Groups** | **D1** | ~130 LOC | ✅ done | | **Batch 4 — Group model** | **D2** | ~71 LOC | ✅ done | **Every batch was followed by:** compile-all + app-factory boot + route smoke test, so hidden dependencies were caught before moving on. --- ## How I verified this (so you can trust it) | Check | Method | |---|---| | Module reachability | AST import extraction + `register_blueprint` cross-reference | | Route usage | `url_for('endpoint')` **and** literal path matching against all templates/JS | | Broken columns | Compared every `var.attr` access against live SQLite `PRAGMA table_info` | | Dynamic attributes | Manually inspected `get_content_ordered()` to rule out false positives | | Duplicate bodies | `ast.dump` body hashing across all functions (result: 0 exact duplicates) | **Reproduce anytime:** ``` ./.venv/bin/python docs/tools/sanitize_report.py # dead code + broken refs ./.venv/bin/python docs/tools/sanitize_audit.py # full function inventory ./.venv/bin/python docs/tools/sanitize_templates.py # orphan templates ./.venv/bin/python docs/tools/smoke_test.py # post-change smoke test ``` --- ## ⚠️ Rollback / hygiene notes 1. **`docs/legacy code/` is excluded from the Docker image** (via `legacy code/` and `**/legacy code/` in `.dockerignore`) so it never ships to production or bloats the build. 2. It is **not** git-ignored, so it will appear in `git status`. Decide: - commit it as a recovery point, or - add `legacy code/` to `.gitignore` if you'd rather rely on git history. 3. Deleting files listed here is **not** recoverable from git unless committed first — the `docs/legacy code/` copy is your safety net.
