# Hobbesgram — Changelog


## v1.07

### Theming overhaul

- **CSS custom properties:** The entire inline style block in `templates/header.php`
  now uses CSS custom properties (`--c-*`) on `:root`. All PHP color echoes have
  been removed from the template; every element references variables.
- **`THEME_PRESETS` constant** added to `config.php` — five named presets with
  full color arrays: OS/2 Classic, Dark Mode, Green Terminal, Hobbes OG, Amber.
- **Site-default preset selector** in Admin → CSS. The chosen preset key is
  saved as `active_preset` in `settings.json`. Applying a named preset marks it
  active; editing individual palette values clears the active preset name.
- **Per-user theme override:** Users can select a personal display theme from
  their Profile page. The selection is stored as `theme_preset` in their user
  JSON and applied at header render time, overriding the site default. Choosing
  "Site Default" reverts to the admin-selected preset.
- **Links styled as buttons** site-wide via a global `a { ... }` rule with
  inverse-color hover. Structural links (header, nav, sidebar, tag pills) use
  targeted overrides to opt out of the button appearance.
- **Semantic status classes** — `.status-ok`, `.status-warn`, `.status-err` —
  replace hardcoded hex color strings throughout admin pages (meta_merge, repair,
  bulk_delete, admin dashboard stat numbers).
- **Readability fixes** in `pages/admin/meta_merge.php`, `repair.php`, and
  `bulk_delete.php`: hardcoded white and off-white backgrounds replaced with
  `var(--c-panel-bg)` and `var(--c-tr-alt)`; hardcoded border colors replaced
  with `var(--c-border)`.

### Admin: file rename

- Admins can rename the physical file on disk from the Danger Zone section of
  `/file/edit/{id}`.
- Validation: extension must match the original; the new name is passed through
  `safe_filename()`; a collision check via `realpath()` prevents overwriting an
  existing file.
- `original_name` and `stored_name` are updated in metadata. If a category move
  is requested in the same form submission, the move step uses the post-rename
  path.
- Orphaned-file case: if the physical file is missing, metadata is updated only.

### Admin: Quality Reports (`/admin/reports`)

New page with three reports for archive hygiene:

- **Duplicate Files** (`?r=duplicates`): groups approved files by size, then
  computes MD5 within each size group to confirm true duplicates. Shows each
  group with file locations and Edit links.
- **Same Filename** (`?r=samename`): groups files by lowercase filename
  regardless of category path; highlights only groups with two or more locations.
- **Missing Descriptions** (`?r=nodesc`): lists approved files whose description
  is absent or a placeholder value ("Unknown", "N/A", etc.).

All reports link directly to `/file/edit/{id}` for quick remediation.

### Admin: Archive.org mirroring (`/admin/mirror`)

- **Credentials** stored in `settings.json` under `archiveorg` (key, secret,
  collection); configured in Admin → Settings → Archive.org Mirror Credentials.
- **Per-file upload:** PUT to `https://s3.us.archive.org/hobbesgram-{id}/{filename}`
  using `Authorization: LOW key:secret`. All available metadata fields are sent
  as `x-archive-meta-*` headers. `x-archive-auto-make-bucket: 1` creates the
  item on first upload.
- **Batch upload:** selectable batch size (5, 10, 25, or 50); uploads the next
  N unmirrored approved files in sequence. `set_time_limit(7200)` and
  `CURLOPT_TIMEOUT => 7200` handle large files.
- On success, `archiveorg_id` and `archiveorg_ts` are saved to file metadata.
  The file detail page shows an Archive.org link when `archiveorg_id` is set.
- Mirror status panel shows mirrored / unmirrored / total counts.
- Re-upload button available for already-mirrored files.
- Admin → index links updated to include Quality Reports and Mirror to Archive.org.

### wget / curl HTTP Basic Auth

- `auth_try_basic()` added to `includes/auth.php`. Checks `PHP_AUTH_USER` /
  `PHP_AUTH_PW` (set by Apache `CGIPassAuth On`) and falls back to parsing the
  `Authorization` header from `HTTP_AUTHORIZATION` or `REDIRECT_HTTP_AUTHORIZATION`
  (set by `.htaccess` `RewriteRule E=HTTP_AUTHORIZATION`).
- Static helper `_basic_auth_flag()` tracks whether the current request was
  authenticated via Basic Auth within the PHP request cycle.
- `auth_try_basic()` is called immediately after `auth_start()` in `index.php`.
- **401 challenge:** Unauthenticated requests to `/download/*` return
  `HTTP 401 Unauthorized` with a `WWW-Authenticate: Basic realm="..."` header
  and a plain-text body showing `wget` and `curl` usage, so command-line tools
  know to prompt for credentials.
- **`.htaccess`** updated with `CGIPassAuth On` and
  `RewriteRule ^ - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]` for broad
  shared-hosting compatibility.
- File detail page shows a pre-filled `wget` command for logged-in users.

### wget / curl download log

- `DLLOG_FILE` constant in `config.php` points to `data/index/dllog.json`.
- `dllog_append()` and `dllog_load()` added to `includes/storage.php`. Log is
  capped at 5,000 entries (oldest entries dropped when cap is reached).
- `pages/download.php` calls `dllog_append()` whenever `basic_auth_user()` is
  non-null, recording: timestamp, username, file ID, filename, IP address,
  User-Agent string.
- **Download Log tab** added to `/admin/mirror`. Shows all log entries most-
  recent-first, paginated at 50 per page (columns: date/time, user, file,
  IP, User-Agent).

## v1.06

### Meta Merge: ZIP bundle support

- The Meta Merge upload form now accepts `.zip` files in addition to `.txt`
  files. Each `.txt` entry inside the ZIP is extracted and parsed as a separate
  source; all matched entries are merged in a single review session.
- Upload size overrun detection: when PHP silently drops the POST body because
  `post_max_size` is exceeded, an informative error is shown rather than a blank
  form.

### Meta Merge: improved filename auto-matching

- A file is now auto-matched when its filename is unique across the entire
  archive, regardless of whether a `DIR` path was present in the `.txt` entry.
  Previously auto-match only fired when the path field was empty.

### Storage: legacy encoding robustness

- `storage_write()` now uses `JSON_INVALID_UTF8_SUBSTITUTE` when encoding JSON.
  Invalid byte sequences (e.g. CP850 / CP437 characters in legacy OS/2 text
  files) are replaced with U+FFFD instead of causing `json_encode()` to return
  `false` and silently lose data.


---


## v1.05

### Shared hosting server config

- **`.htaccess`** added to web root with: `Options -Indexes`,
  `mod_rewrite` rules for clean URLs, `DirectoryIndex index.php`,
  PHP limit overrides (`upload_max_filesize 200M`, `post_max_size 210M`,
  `memory_limit 256M`, `max_execution_time 300`), block rules for direct
  access to `.json` and `.ini` files.
- **`.user.ini`** added for PHP-FPM environments (equivalent limit overrides
  without requiring `.htaccess` PHP directives support).


---


## v1.04

### Admin: Archive Repair tool (`/admin/repair`)

New read-only integrity report for administrators:

- **Orphaned files** — physical files in `data/uploads/` that have no matching
  metadata record in `data/files/`.
- **Empty-browse categories** — categories with no approved files and no
  sub-categories (candidates for pruning).
- **Duplicate categories** — category names that appear more than once under
  the same parent node.

No automatic changes are made; the report is informational only.


---


## v1.03 (2026-03-24)

### Meta Merge tool (Admin / Editor, `/admin/meta-merge`)

- Upload a `.txt` file to bulk-import metadata into existing archive entries
  without re-uploading the files themselves.
- Parses two formats automatically:
  - **hobbes.txt:** dashed-separator blocks with `DIR` / `FILE` / `DESC` fields.
  - **pmmail.txt:** aligned `key: value` pairs (Archive Filename, Short
    Description, Long Description, Proposed directory, Your name, Program URL,
    Operating System/Version, Additional requirements).
- Matches entries to archive files by normalising the `DIR` path to slugified
  category segments and comparing against each file's stored
  `category_upload_path` + `original_name`.
- Three-phase workflow: upload → review report → apply.
- Review page shows:
  - *Matched entries* — before/after diff table per field; individual checkboxes
    to include or exclude each entry.
  - *Unmatched entries* — filename-only suggestions, manual file-ID input, or
    Skip.
  - *Skipped summary* — entries marked skip listed for reference.
- Merge mode: fill blank/"Unknown" fields only (default), or overwrite all
  existing values.
- Approved files are re-indexed in the search index after merge.
- Temporary sessions stored in `data/merges/` and auto-expired at 2 hours.

### Bulk Delete tool (Admin only, `/admin/bulk-delete`)

- Select any category to list its files (approved and pending).
- Per-page selector: 25 / 50 / 100 / All. Warning banner when "All" is chosen
  with more than 250 files.
- "Select all on this page" and "Select ALL N files in this category" checkboxes.
- JavaScript confirmation dialog shows the deletion count before committing.
- Removes physical file from disk, metadata JSON, and all search index entries.
- Empty category upload directories are pruned after deletion.

### Single-file delete from edit page (Admin only)

- Danger Zone section added at the bottom of `/file/edit/{id}`.
- Visible to admin role only. Confirmation dialog includes the filename.
- Handled by `POST /admin/file-delete/{id}`; redirects to the file's category
  browse page after deletion.

### Download counter displayed in all views

- **browse.php:** "DLs" column added to the file listing table.
- **file.php:** "Downloads" row added to the file detail info table.
- **search.php:** "DLs" column added to search results table.
- Counter has been tracked since v1.01; this release makes it visible to all
  users including unauthenticated OS/2 guests.

### Approve All Web Uploads button (`/pool`)

- A summary bar appears when one or more web-uploaded files are pending approval.
- "Approve All Web Uploads" approves every pending web upload in a single action
  (`POST /pool/approve_all`, CSRF-protected).
- FTP single files and FTP folder imports are intentionally excluded (they require
  metadata to be filled in or imported first).
- JavaScript confirmation dialog shows the count before committing.

### Admin dashboard links updated

- "Meta Merge" and "Bulk Delete" (styled red) buttons added to the Site
  Management panel.

## v1.02

### FTP folder batch import (Editor+, `/pool`)

- Drop an entire directory tree into `data/pool/` via FTP.
- The pool listing detects folders and presents a Batch Import Folder button.
- Sub-folders are mapped to nested categories using `category_find_or_create()`,
  which creates missing categories on the fly (slugified, de-duplicated) without
  overwriting existing ones.
- Files receive titles derived from their filenames; required fields default to
  "Unknown" and can be corrected post-import.
- Approve-immediately checkbox available for trusted bulk imports.
- The pool folder is recursively removed after a successful import.
- Reject & Delete Folder button purges the folder without importing.

### "Hobbes OG" CSS preset (Admin → CSS)

- Fourth built-in color preset added.
- Deep navy blue palette inspired by the original hobbes.nmsu.edu color scheme:
  dark blue panels, cream text, teal accents.

### New helper functions

- **`category_find_or_create()`** (`includes/functions.php`) — looks up a
  category by name + parent; creates it with a unique slug if absent. Used by
  folder import.
- **`category_upload_path_from_cats()`** (`includes/functions.php`) — variant
  of `category_upload_path()` that accepts an explicit array instead of the
  static-cached result. Required during batch import when the category list has
  been mutated but not yet written to disk.
- **`rmdir_recursive()`** (`includes/functions.php`) — recursively removes a
  directory tree. Used to clean up pool folders after import or rejection.
- **`pool_folder_file_count()`**, **`pool_folder_files()`**
  (`includes/storage.php`) — helpers for counting and listing files inside pool
  folders during batch import.

### Fixed: Pool route regex (`index.php`)

- Changed `[a-z]+` to `[a-z_]+` so that `import_folder` and `reject_folder`
  action names are matched correctly.
