feat(upload): upload assistant in the browser and as a cli by florianjs · Pull Request #99 · florianjs/trackarr

florianjs · 2026-11-09T15:02:22Z

Summary

Make publishing a release as easy as possible: one file or folder in, a published torrent out, from the browser (/upload/assistant) or a terminal (trackarr-upload.mjs).

Step	Web	CLI
`.torrent` (private, personal announce, `source` = tracker host)	WebCrypto, File.slice	node:crypto, fs
MediaInfo (largest video, local path stripped)	mediainfo.js (WASM)	`mediainfo` binary (optional)
Screenshots (spread over the video)	browser decoder, fallback ffmpeg.wasm	`ffmpeg` (HDR tone-mapped with zimg)
Hosting	relayed by the tracker to Pixhost (adult flag)	Pixhost directly
Description	BBCode in 8 languages, editable, preview, copy	written next to the `.torrent`
Publish	session	`Authorization: Bearer <API key>`

The tracker keeps the info hash of a private, announce-free info dict, so the uploader seeds the file just created.

Changes

shared/utils/release/: torrent builder, MediaInfo summary, release name parser, description builder + labels (en fr es de it zh ja ru)
shared/utils/bbcode.ts: BBCode to HTML (everything escaped, whitelisted tags, http(s) links/images only), renderDescription picks BBCode or Markdown; DOMPurify still applies
Server: requireUploader (session or API key) on POST /api/torrents, GET /api/upload-assistant/config, POST /api/upload-assistant/screenshot (rate limited, 10 MB, type by magic bytes), PIXHOST_API_URL
CSP: 'wasm-unsafe-eval' (WebAssembly only, no JS eval), blob: for img-src and new media-src
Description limit 10,000 → 50,000 characters (full MediaInfo)
CLI bundled by esbuild in prebuild, served at /tools/trackarr-upload.mjs (generated, gitignored)
New deps: mediainfo.js, @ffmpeg/ffmpeg, @ffmpeg/util, @ffmpeg/core (wasm served from our origin, loaded only on the assistant page), dev esbuild. Lockfile: additions only.
Docs: doc/guide/upload-assistant.md, env reference, README, getting started; i18n assistant.json x8

Notes

The API key (Integrations page) can now upload too: a leaked *arr key allows uploads in the user's name until regenerated.
ffmpeg.wasm 0.12: its MJPEG encoder crashes ("memory access out of bounds"), screenshots go through PNG then canvas JPEG; -nostdin and timeouts bound every call.

Test plan

Unit tests: torrent builder (pieces across files, hash kept by normalizeTorrent), MediaInfo, release names, description in several languages, BBCode rendering and XSS cases, Pixhost URL check; full suite 371/371
npm run build (WASM assets and worker emitted, CLI bundled)
CLI against a local tracker: folder + single file, category by path, dry run, unknown tag / bad key errors, published hash = local hash
Web in Chrome: MP4 (browser decoder) published with a deselected screenshot, BBCode page render with spoilers; AVI MPEG-4 (ffmpeg.wasm fallback) 6/6 screenshots
Folder drag and drop in a real browser
Real HEVC MKV in the browser, HDR tone mapping in the CLI

Summary by CodeRabbit

New Features
- Added a web upload assistant for files and folders that analyzes media, captures screenshots, creates torrent files and BBCode descriptions, and supports publishing or downloading results.
- Added a command-line upload tool for preparing releases, generating screenshots, and publishing.
- Added support for BBCode descriptions, including improved rendering and expanded description length limits.
- Added localized upload assistant content in eight languages.
Documentation
- Added upload assistant guidance and CLI instructions to the documentation.

One file or folder in, a published torrent out: private .torrent with the personal announce URL (info hash kept by the tracker, so the uploader seeds the local file), MediaInfo, screenshots hosted on Pixhost (adult flag), and a BBCode description in one of 8 languages. - shared core: isomorphic torrent builder, MediaInfo summary, release name parser, BBCode description builder - web page /upload/assistant: mediainfo.js, screenshots with the browser decoder and an ffmpeg.wasm fallback (WORKERFS, PNG then JPEG), WebCrypto hashing, edit, preview, publish - CLI tools/upload-cli bundled by esbuild at build time and served at /tools/trackarr-upload.mjs (Node 20+, ffmpeg, mediainfo) - descriptions render BBCode (escaped, whitelisted tags, http(s) only) or Markdown; limit raised to 50,000 characters - server: API key auth (Bearer) for uploads, assistant config endpoint, screenshot relay to Pixhost; CSP allows wasm and blob: media/images Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Walkthrough

The pull request adds browser and CLI upload assistants. Both prepare torrent files and release descriptions, with optional MediaInfo and screenshots. Server endpoints provide uploader configuration, screenshot hosting, and torrent publishing support.

Changes: Upload Assistant

Layer / File(s)	Summary
Release metadata and torrent construction `shared/utils/release/*`, `tests/upload-assistant.test.ts`	Shared utilities parse release names and MediaInfo, define localized description labels, format release descriptions, and build torrent data. Tests cover parsing, formatting, torrent construction, and related output.
BBCode conversion and description rendering `shared/utils/bbcode.ts`, `app/utils/markdown.ts`, `app/components/EditTorrentModal.vue`, `app/components/UploadTorrentModal.vue`, `app/pages/torrents/[hash].vue`, `tests/upload-assistant.test.ts`	BBCode conversion escapes content and validates formatting inputs. Description previews use the BBCode-aware renderer, and torrent pages add styles for rendered elements.
Uploader authorization and upload endpoints `server/utils/uploaderAuth.ts`, `server/utils/pixhost.ts`, `server/api/upload-assistant/`, `server/api/torrents/`, `server/utils/schemas.ts`	The server adds uploader authorization, assistant configuration and screenshot relay endpoints, and Pixhost upload utilities. Torrent descriptions accept longer text.
Browser assistant workflow and integration `app/pages/upload/assistant.vue`, `app/components/StepLine.vue`, `app/utils/uploadAssistant/`, `app/pages/index.vue`, `app/components/UploadTorrentModal.vue`, `nuxt.config.ts`, `server/utils/csp.ts`, `i18n/locales//assistant.json`, `doc/guide/upload-assistant.md`, `doc/guide/getting-started.md`, `doc/reference/env.md`, `doc/.vitepress/config.ts`, `README.md`, `tests/csp.test.ts`, `.gitignore`	The browser page selects release files, analyzes media, captures screenshots, builds torrents, and supports editing, downloading, and publishing. The change also adds entry points, localization, documentation, browser processing configuration, and the CLI bundle ignore rule.
CLI preparation and publishing `tools/upload-cli/main.ts`, `scripts/build-cli.mjs`, `package.json`	The CLI scans files, processes media and screenshots, builds a torrent and description, writes output files, and can publish to the tracker. A build script bundles the CLI for Node 20.

Full details: Title check

Explanation

The title "feat(upload): upload assistant in the browser and as a cli" matches the main change. The PR adds a browser upload assistant at /upload/assistant and a CLI (trackarr-upload.mjs) that build torrents, generate MediaInfo and screenshots, create descriptions, and publish releases. The title is short, specific, and uses a conventional-commit prefix. It does not mention the supporting API, CSP, and i18n changes, which is expected.

Full details: Docstring Coverage

Explanation

Docstring coverage is 34.88% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 43 functions across 24 files. (3 skipped: 3 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

only still-valid issues, skip the rest with a brief reason, keep changes
minimal, and validate.

Inline comments:
Review comments at @app/pages/upload/assistant.vue:
- Line 417: Update runMedia and runHash to verify that picked still refers to
the same release after each asynchronous operation before writing shared state
or creating object URLs; also guard hash progress callbacks and stale-task error
handling. Preserve the existing flow for the current release so tasks from a
prior selection cannot overwrite the newly selected release’s state.

Review comments at @i18n/locales/fr/assistant.json:
- Line 10: Update the French privacy notice in the private translation entry to
use « seules les captures » instead of « seuls les captures », preserving the
rest of the text.

Review comments at @server/api/upload-assistant/config.get.ts:
- Around line 15-16: Update the announceUrl construction in the upload-assistant
configuration handler so API-key-authenticated callers are not given the
account’s permanent passkey unless a passkey reset that invalidates leaked
credentials is confirmed. Establish which supported behavior applies—restrict
the passkey URL to session-authenticated callers or ensure passkey resets revoke
it—and preserve the CLI’s required way to obtain an announce URL.

Review comments at @shared/utils/bbcode.ts:
- Line 34: Update looksLikeBbcode to avoid scanning the remaining description
for every opening tag: bound opening-tag argument matching, then check for a
matching closing tag using a lookup performed at most once per tag name.
Preserve case-insensitive matching and return true only when a closing tag
occurs after an opening tag.
- Around line 105-110: Limit nesting in parse so opening tags beyond a fixed
maximum depth are appended as plain text rather than pushed onto the stack.
Preserve normal parsing within the limit, ensuring deeply nested input cannot
drive recursive rendering in renderNode, renderChildren, or textOf beyond a safe
depth.

Review comments at @shared/utils/release/description.ts:
- Line 186: Update the MediaInfo escaping in the `out.push` expression so it
neutralizes closing `code` tags recognized by the BBCode parser, including forms
with arguments such as `[/code=x]`, rather than matching only the bare `[/code]`
form. Preserve the remaining MediaInfo text and the surrounding spoiler and
code-block structure.

Review comments at @shared/utils/release/mediainfo.ts:
- Around line 65-66: Update the channel-count condition in channelLayout so
layouts with fewer than 6 channels, including 3 and 5, use the existing count.0
format; only counts of 6 or more should use the count-minus-one.1 format.
Preserve the existing behavior for 2-channel and 8-channel tracks.

Review comments at @tools/upload-cli/main.ts:
- Around line 280-308: Update the `buildTorrent` file-reading callbacks to open
each file within `read` and close its handle in a `finally` block after reading,
removing the eager `Promise.all` handles setup and cleanup. Preserve the
existing offset-based read loop and progress behavior; ensure each callback
releases its descriptor even if reading fails.

Reject a pending drop when a release is already selected

If a drop is still being read when the user selects and publishes another release, its completion can replace that release during publishing. This can prevent the torrent submission or show the old publication result for the new release.

Outside-diff comment (stale drop replacing a release) fixed in 740dfe6: a dropped folder is read asynchronously, so a token now invalidates the drop as soon as another file is picked, and a drop that completes while a release is already in progress is ignored.
