1 | # Developer Onboarding
2 |
3 | Welcome! This guide gets you from clone to a working Universal Manga Downloader (UMD) environment with the quality gates ready to run.
4 |
5 | ## Prerequisites
6 |
7 | - Python **3.11+** (CI runs 3.14)
8 | - Git
9 | - Tkinter headers (`python3-tk` on most Linux distros; bundled on Windows/macOS)
10 | - `pipx` (optional, recommended for global installs)
11 |
12 | ## Setup (5 Steps)
13 |
14 | 1. Clone the repository
15 | ```bash
16 | git clone https://github.com/0xH4KU/universal-manga-downloader.git
17 | cd universal-manga-downloader
18 | ```
19 | 2. Create a virtual environment (recommended for PEP 668 systems)
20 | ```bash
21 | python3 -m venv .venv
22 | source .venv/bin/activate # Windows: .venv\Scripts\activate
23 | ```
24 | 3. Install runtime and editable package
25 | ```bash
26 | pip install -r requirements.txt
27 | pip install -e .
28 | ```
29 | 4. Install development tooling
30 | ```bash
31 | pip install ruff mypy pytest
32 | ```
33 | 5. Confirm the interpreter and key packages
34 | ```bash
35 | python --version
36 | pip list | grep -E "(requests|beautifulsoup4|Pillow|cloudscraper|sv-ttk)"
37 | ```
38 |
39 | > If `pip` is blocked by system package management, stay inside the `.venv` above or use `pipx install .` to isolate the install.
40 |
41 | ## Verify the Application
42 |
43 | - Run diagnostics: `umd --doctor`
44 | - Launch the GUI: `umd` (or `python -m manga_downloader`)
45 | - Inspect configuration: `umd --config-info`
46 |
47 | Confirm you can search Bato/MangaDex, view chapters, and queue a download; this exercises plugin discovery, HTTP clients, and converters.
48 |
49 | ## Quality Gates
50 |
51 | Execute from the repository root with the virtual environment activated:
52 |
53 | ```bash
54 | ruff check .
55 | mypy manga_downloader.py config.py umd_cli.py core/ plugins/ services/ ui/ utils/ --no-error-summary
56 | pytest tests -q
57 | ```
58 |
59 | ## Where to Go Next
60 |
61 | - [DEVELOPMENT.md](DEVELOPMENT.md) — day-to-day workflow, branch/commit guidance, and commands.
62 | - [ARCHITECTURE.md](ARCHITECTURE.md) — threading boundaries, plugin discovery, and data flow.
63 | - [PLUGINS.md](PLUGINS.md) — how to extend UMD with new parsers or converters.

1 | # Contributing Guide
2 |
3 | Thank you for helping improve Universal Manga Downloader! This guide outlines the expectations for contributors and how to get changes merged smoothly.
4 |
5 | ## Core Expectations
6 |
7 | - Work from a feature branch (for example, `feature/new-parser` or `fix/resume-race`).
8 | - Follow the non-commercial license (CC BY-NC-SA 4.0); no telemetry, ads, or embedded secrets.
9 | - Keep changes small and well-documented; update relevant `.md` files when behavior shifts.
10 | - Use the shared tooling (`ruff`, `mypy`, `pytest`) and avoid `print` in production code.
11 |
12 | ## Getting Set Up
13 |
14 | Complete the steps in [ONBOARDING.md](ONBOARDING.md) to create a virtual environment, install dependencies, and verify the GUI launches. Reactivate the venv for every session:
15 |
16 | ```bash
17 | source .venv/bin/activate # Windows: .venv\Scripts\activate
18 | ```
19 |
20 | ## Development Workflow
21 |
22 | 1. Sync: `git fetch --all --prune` and `git pull --ff-only` (set upstream if needed).
23 | 2. Branch: `git checkout -b feature/your-change`.
24 | 3. Code: keep commits focused with clear messages (`feat:`, `fix:`, `docs:`, `refactor:`, `test:`, `chore:`).
25 | 4. Validate: run `ruff check .`, `mypy ...`, and `pytest tests -q`.
26 | 5. Document: update README/PLUGINS/DEVELOPMENT/ARCHITECTURE as appropriate.
27 |
28 | ## Pull Requests
29 |
30 | Include the following in every PR:
31 |
32 | - Summary of what changed and why.
33 | - Tests executed (commands and manual steps).
34 | - Screenshots/GIFs for UI updates when relevant.
35 | - Breaking changes, if any, called out explicitly.
36 | - Issue links (`Fixes #123`) where applicable.
37 |
38 | ## Validation Commands
39 |
40 | | Purpose | Command |
41 | | --- | --- |
42 | | Lint | `ruff check .` |
43 | | Type check | `mypy manga_downloader.py config.py umd_cli.py core/ plugins/ services/ ui/ utils/ --no-error-summary` |
44 | | Tests | `pytest tests -q` |
45 | | GUI smoke test | `python -m manga_downloader` (or `umd`) |
46 |
47 | ## Community Standards
48 |
49 | - Be respectful and responsive in reviews.
50 | - Prefer modular changes; break up large GUI work into smaller patches.
51 | - Ask questions early—open an issue or draft PR if direction is unclear.
52 | - Credit upstream sources and avoid copying licensed content without permission.

1 | # Development Guide
2 |
3 | This guide covers the day-to-day workflow for contributing to Universal Manga Downloader (UMD) 1.3.1.
4 |
5 | ## Workflow Overview
6 |
7 | - Use a dedicated branch per change (for example, `feature/pause-status` or `fix/mangadex-timeout`).
8 | - Sync before starting work: `git fetch --all --prune` then `git pull --ff-only` (set an upstream if needed).
9 | - Keep commits focused and descriptive (`feat:`, `fix:`, `docs:`, `refactor:`, `test:`, `chore:`).
10 | - Update documentation alongside behavior changes and keep logging consistent (`logging` module only).
11 |
12 | ## Environment
13 |
14 | Activate the `.venv` created during onboarding and ensure the editable install is present:
15 |
16 | ```bash
17 | source .venv/bin/activate # Windows: .venv\Scripts\activate
18 | pip install -e .
19 | pip install -r requirements.txt
20 | pip install ruff mypy pytest
21 | ```
22 |
23 | Re-run the installs after pulling dependency changes.
24 |
25 | ## Core Commands
26 |
27 | | Purpose | Command |
28 | | --- | --- |
29 | | Lint | `ruff check .` |
30 | | Type check | `mypy manga_downloader.py config.py umd_cli.py core/ plugins/ services/ ui/ utils/ --no-error-summary` |
31 | | Tests | `pytest tests -q` |
32 | | GUI | `python -m manga_downloader` (or `umd`) |
33 | | Diagnostics | `umd --doctor` |
34 |
35 | Run lint, type, and test checks before pushing. CI runs the same suite.
36 |
37 | ## Coding Notes
38 |
39 | - Type hints use Python 3.11+ syntax (`list[str]`, `| None`).
40 | - Guard Tkinter updates from worker threads via `after(...)`.
41 | - When touching download logic, verify pause/resume and cancellation on a long-running chapter.
42 | - Keep plugin behavior defensive—return `None` on parse/convert failures and rely on shared services for network access.
43 |
44 | ## Pull Request Checklist
45 |
46 | - Branch is rebased on the target base (usually `main`).
47 | - `ruff`, `mypy`, and `pytest` all pass locally.
48 | - Docs updated where behavior or workflows changed.
49 | - PR description includes summary, motivation, tests executed, and any screenshots for UI tweaks.
50 | - Reference related issues (for example, `Fixes #123`).
51 |
52 | ## Troubleshooting
53 |
54 | | Issue | Diagnosis | Fix |
55 | | --- | --- | --- |
56 | | `ModuleNotFoundError: ui.logging_utils` | Editable install missing | Re-run `pip install -e .` inside the venv |
57 | | Tkinter window will not open | Tk not installed or display blocked | Install `python3-tk` (Linux) or ensure a display is available |
58 | | Ruff/Mypy fail in CI but not locally | Not using the project venv | Reactivate `.venv` and reinstall dependencies |
59 | | Downloads never resume | Pause event unset | Confirm resume logic calls `_pause_event.set()` |
60 |
61 | Need more context? See [ARCHITECTURE.md](ARCHITECTURE.md) for design details and [PLUGINS.md](PLUGINS.md) when extending parsers/converters.

1 | # Architecture Overview
2 |
3 | This document explains how Universal Manga Downloader (UMD) 1.3.1 is structured and how data moves through the system.
4 |
5 | ## Design Principles
6 |
7 | - Separate UI, orchestration, plugins, and infrastructure concerns.
8 | - Auto-discover plugins; avoid code changes when adding parsers or converters.
9 | - Keep threading predictable: UI on the Tk loop, work in executors, with lock-backed queue state.
10 | - Prefer defensive error handling and strong typing (Python 3.11+ syntax).
11 |
12 | ## Layers and Responsibilities
13 |
14 | | Layer | Modules | Responsibilities |
15 | | --- | --- | --- |
16 | | UI | `manga_downloader.py`, `ui/app.py`, `ui/logging_utils.py` | Tkinter app (Browser, Downloads, Settings tabs), event wiring, log setup |
17 | | Core | `core/queue_manager.py`, `core/download_task.py` | Queue state, worker coordination, pause/resume, cancellation, converter orchestration |
18 | | Services | `services/bato_service.py`, `services/mangadex_service.py` | Search and metadata retrieval for Bato and MangaDex |
19 | | Plugins | `plugins/base.py` + parsers/converters | Auto-discovered implementations that turn pages into images and archives |
20 | | Utilities | `utils/file_utils.py`, `utils/http_client.py` | Download paths, filename sanitization, disk checks, HTTP session pooling |
21 | | Configuration | `config.py` | Frozen dataclasses exposed via `CONFIG` for UI sizes, worker counts, timeouts, endpoints, and PDF settings |
22 |
23 | ## Data Flow
24 |
25 | ### Search and Series Browsing
26 |
27 | 1. User selects provider (Bato/MangaDex) and submits a query from the Browser tab.
28 | 2. The UI delegates to the corresponding service to fetch search results.
29 | 3. Selecting a series triggers chapter list retrieval and populates the chapter view.
30 |
31 | ### Download Workflow
32 |
33 | 1. Queueing a chapter registers it with `QueueManager` and refreshes the chapter executor.
34 | 2. Each queued item runs a `DownloadTask` inside a ThreadPoolExecutor sized by `CONFIG.download`.
35 | 3. The task fetches the chapter HTML/JSON via `ScraperPool`, then asks `PluginManager` to pick a parser that can handle the URL.
36 | 4. Parsed image URLs are downloaded concurrently with a bounded image worker pool guarded by a semaphore (`max_total_image_workers`).
37 | 5. When downloads finish, enabled converters (PDF/CBZ) run in sequence using the downloaded files.
38 | 6. `QueueManager` records status transitions; UI updates are marshalled via Tk `after(...)` to keep thread safety.
39 |
40 | ## Threading Model
41 |
42 | - **Main thread**: Tk event loop; all widget updates occur here via scheduled callbacks.
43 | - **Chapter workers**: ThreadPoolExecutor limited by `default_chapter_workers`–`max_chapter_workers` (1–10 by default).
44 | - **Image workers**: Per-chapter ThreadPoolExecutor capped by `default_image_workers`–`max_image_workers` (4–32), plus a global `max_total_image_workers` limit (48).
45 | - **Pause/Resume**: A shared `threading.Event` (`_pause_event`) blocks progress when cleared; resume sets the event.
46 | - **Cancellation**: Futures are tracked by queue ID; cancelling stops work after the current safe checkpoint.
47 |
48 | ## Plugin System
49 |
50 | - `PluginLoader` scans `plugins/` for `.py` files (excluding `__init__.py` and private files), loading them in isolation.
51 | - Classes inheriting `BasePlugin` (parsers) or `BaseConverter` (converters) register automatically with `PluginManager`.
52 | - Duplicate `get_name()` values per plugin type are ignored after the first successful load.
53 | - Optional hooks: `on_load` and `on_unload` allow caching or cleanup when toggled in the Settings tab.
54 | - Parser output uses `ParsedChapter` (title, chapter label, image URLs); converters accept file paths plus `ChapterMetadata`.
55 |
56 | ## Configuration
57 |
58 | `config.py` defines frozen dataclasses surfaced through `CONFIG`:
59 |
60 | - `UIConfig`: window dimensions (1100x850 default), minimum sizes, queue/progress update intervals.
61 | - `DownloadConfig`: chapter/image worker bounds (1–10 and 1–32), global image worker cap (48), timeouts (30s requests/15s search/20s series), retries (3 with 1.0s backoff), scraper pool size (8).
62 | - `ServiceConfig`: Bato and MangaDex endpoints, paging limits, language defaults, and rate-limit delay (0.5s).
63 | - `PDFConfig`: default resolution (100 DPI) and supported input formats.
64 |
65 | Use `CONFIG` instead of hardcoded values; expose changes here so CLI and UI stay in sync.
66 |
67 | ## Extension Points
68 |
69 | - **New site parser**: add `plugins/_parser.py`, subclass `BasePlugin`, implement `get_name`, `can_handle`, and `parse`. Keep network access in `services/`.
70 | - **New converter**: add `plugins/_converter.py`, subclass `BaseConverter`, return the output file path or `None` on failure.
71 | - **New service helper**: extend `services/` to encapsulate HTTP interactions and reuse shared scraper sessions.
72 |
73 | ## Reliability and Safety Notes
74 |
75 | - Network retries back off per chapter (`max_retries=3`, `retry_delay=1.0s`).
76 | - Download directory access and disk space are validated before workers run.
77 | - Exceptions in plugins are logged and surfaced to the UI without crashing the application.
78 | - All state mutations in `QueueManager` are guarded by an `RLock` to keep progress consistent across threads.

14 | - [Updating, Dependencies & Rolling Back](#updating-dependencies--rolling-back)
15 |
16 | ---
17 |
18 | ## Quick Start
19 |
20 | 1. **Find a plugin** – browse the official repo (`plugin_repository/official`), wiki listings, or trusted community posts and copy the GitHub Raw URL.
21 | 2. **Open the app** – use Settings → Remote Plugins (Beta) for manual URLs/rollback/whitelists.
22 | 3. **Preview & install** – every install opens a metadata dialog (name, version, dependencies, checksum) before writing to disk.
23 | 4. **Stay updated** – click **Check Updates** (GUI) or use `umd plugins check-updates` / `umd plugins update --all` in scripts/CI.
24 |
25 | > Note: The Plugin Market preview has been removed, so installations rely entirely on manual GitHub Raw URLs from trusted sources.
26 |
27 | > Need maximum flexibility? Toggle “Allow all GitHub Raw sources (use at your own risk)” in the Remote Plugins panel to bypass the whitelist—UMD will warn you before enabling this mode.
28 |
29 | > Prefer the terminal? Skip the GUI entirely with commands such as `umd plugins list`, `umd plugins install `, `umd plugins update MangadexEnhanced`, or `umd plugins rollback MangadexEnhanced --version 1.2.3`.
30 |
31 | ## Safety Checklist
32 |
33 | - Only install plugins from sources you trust.
34 | - Inspect the plugin code before installing; the preview dialog shows the declared metadata, checksum, and dependencies.
35 | - Maintain the **Allowed Sources** list in Settings to restrict installs to trusted repositories.
36 | - Keep a backup of `plugins/plugin_registry.json` if you plan to sync between devices.
37 |
38 | ## Registry, History & Bundles
39 |
40 | - Installed files live in the standard `plugins/` directory. Single-file plugins end with `.py`; multi-file bundles unpack into `plugins//` packages.
41 | - Metadata (display name, version, author, checksum, dependencies, artifact type) and **history snapshots** are recorded in `plugins/plugin_registry.json`.
42 | - Every update stores the previous version under `plugins/remote_history//`; rollbacks copy back either the single file or the entire directory tree.
43 | - Deleting registry entries through the UI removes the corresponding file/directory and its history folder.
44 |
45 | ## CLI Management
46 |
47 | The `umd` binary ships with subcommands tailored for remote plugins:
48 |
49 | | Command | Purpose |
50 | | --- | --- |
51 | | `umd plugins list` | Show installed remote plugins, types, versions, and source URLs. |
52 | | `umd plugins install [--force]` | Install (or replace) a plugin from a GitHub Raw URL. |
53 | | `umd plugins uninstall ` | Remove the plugin file and registry entry. |
54 | | `umd plugins check-updates` | Report all available remote plugin updates. |
55 | | `umd plugins update --all` or `umd plugins update ` | Upgrade plugins in bulk or selectively. |
56 | | `umd plugins history ` | Display stored snapshots (version, timestamp, checksum). |
57 | | `umd plugins rollback [--version V] [--checksum HASH]` | Restore a previous version from history. |
58 | | `umd plugins install-deps ` | Install any missing dependencies declared by the plugin. |
59 |
60 | All commands honor the same whitelist/registry as the GUI, making headless installations and CI automation straightforward.
61 |
62 | ## Troubleshooting
63 |
64 | | Issue | Resolution |
65 | | --- | --- |
66 | | "仅支持 raw.githubusercontent.com 链接" | Copy the **Raw** link from GitHub. |
67 | | "该来源不在白名单" | Add the prefix to **Allowed Sources** in Settings, then retry. |
68 | | "所有插件均为最新版本" | Appears after **Check Updates** completes with no newer versions. |
69 | | Download timeout | Check proxy settings or retry with a stable network. |
70 | | Plugin not visible after install | Click **Refresh** in Remote Plugins or restart the app. |
71 | | Unable to uninstall | Ensure the plugin isn't selected in another task, then retry from Settings. |
72 | | Want to revert a bad update | Select the plugin and click **History / Rollback** (GUI) or run `umd plugins rollback --version ` (CLI). |
73 |
74 | ## Removing Plugins
75 |
76 | 1. Open Settings → Remote Plugins.
77 | 2. Select the plugin in the list and click **Uninstall Selected**.
78 | 3. The plugin is disabled immediately and removed from disk.
79 |
80 | ## Allowed Sources
81 |
82 | - Manage the whitelist via Settings → Remote Plugins → Allowed Sources.
83 | - Default entry: `https://raw.githubusercontent.com/umd-plugins/official/`.
84 | - Adding new entries requires the same host (`raw.githubusercontent.com`).
85 | - If you frequently install from many repositories, enable the **Allow all GitHub Raw sources** toggle (after acknowledging the warning dialog). Disable it anytime to fall back to the curated whitelist.
86 |
87 | ## Updating, Dependencies & Rolling Back
88 |
89 | - Click **Check Updates** to fetch metadata from each installed plugin; rows with updates turn shaded.
90 | - Use **Check Dependencies** / **Install Missing Deps** (GUI) or `umd plugins install-deps ` to keep requirements satisfied.
91 | - Select a plugin and click **Update Selected** to re-download and replace it in-place, or run `umd plugins update --all` headlessly.
92 | - Every update archives the previous version; use **History / Rollback** (GUI) or `umd plugins rollback` to recover.
93 |
94 | For repository maintainers, see `PLUGIN_REPOSITORY_STRUCTURE.md` for publishing workflows.

54 |
55 | ## Security Best Practices
56 |
57 | When using Universal Manga Downloader, follow these security best practices:
58 |
59 | ### For Users
60 |
61 | 1. **Keep Updated**: Always use the latest version
62 | 2. **Verify Sources**: Only download from official repositories
63 | 3. **Review Permissions**: Be cautious about download directory permissions
64 | 4. **Network Security**: Use HTTPS connections when available
65 | 5. **Dependency Management**: Keep Python and dependencies updated
66 |
67 | ### For Developers
68 |
69 | 1. **Code Review**: All code changes require review before merging
70 | 2. **Dependency Scanning**: Regular security audits via `pip-audit` in CI/CD
71 | 3. **Input Validation**: All user inputs must be validated and sanitized
72 | 4. **Secrets Management**: Never commit credentials or API keys
73 | 5. **Testing**: Security-related changes must include tests
74 |
75 | ## Known Security Considerations
76 |
77 | ### Current Security Measures
78 |
79 | - **Input Sanitization**: All filenames and paths are sanitized to prevent path traversal
80 | - **URL Validation**: URLs are validated before making requests
81 | - **Rate Limiting**: API requests are rate-limited to prevent abuse
82 | - **Circuit Breaker**: Fault tolerance patterns prevent cascading failures
83 | - **Dependency Pinning**: Specific dependency versions prevent supply chain attacks
84 | - **Security Scanning**: Automated pip-audit runs in CI/CD pipeline
85 |
86 | ### Potential Risks
87 |
88 | Users should be aware of the following:
89 |
90 | 1. **Network Requests**: This application makes HTTP requests to manga websites
91 | 2. **File System Access**: The application writes files to your designated download directory
92 | 3. **Third-Party Dependencies**: Security depends on upstream packages
93 | 4. **Cloudflare Bypass**: Uses cloudscraper which may interact with anti-bot measures
94 |
95 | ## Disclosure Policy

1 | # AI Agent Guidelines for Universal Manga Downloader
2 |
3 | These instructions are the source of truth for AI agents working on this repository. Follow them to keep contributions consistent, type-safe, and easy for maintainers to review.
4 |
5 | ## Quick Start Checklist
6 |
7 | - Read `ARCHITECTURE.md`, `ONBOARDING.md`, and `DEVELOPMENT.md`.
8 | - Understand the plugin architecture (`plugins/base.py`) before altering parser/converter behavior.
9 | - Locate relevant files before proposing changes.
10 | - Verify you are on a feature branch (not `main`).
11 |
12 | ## Mandatory Workflow
13 |
14 | ### Environment Setup (blocking)
15 |
16 | Run the following before making code changes:
17 |
18 | ```bash
19 | git fetch --all --prune
20 | git pull --ff-only # if tracking is configured
21 | python3 -m pip install -r requirements.txt
22 | python --version # ensure 3.11+
23 | pip list | grep -E "(requests|beautifulsoup4|Pillow|cloudscraper|sv-ttk)"
24 | ```
25 |
26 | If any step fails, stop and report the issue.
27 |
28 | ### Implementation Cycle
29 |
30 | 1. Understand the request fully before coding.
31 | 2. Create a feature branch.
32 | 3. Make focused changes with clear intent.
33 | 4. Run quality checks: `ruff check .` and `mypy .`
34 | 5. Commit with descriptive messages.
35 | 6. Push and prepare a PR that documents changes, tests, and any breaking notes.
36 |
37 | ## Code Standards
38 |
39 | - Always use `from __future__ import annotations` and Python 3.11+ typing (`list[str]`, `| None`).
40 | - Prefer concrete types (for example, `TypedDict`, `dataclass`) and use `TYPE_CHECKING` to break cycles.
41 | - Logging: `logger.debug/info/warning/error/exception` with `%s` formatting. Never use `print` or f-strings inside log calls.
42 | - Error handling: catch specific exceptions; avoid bare `except`. Return `None` from plugins on recoverable failures.
43 | - Docstrings: include arguments, return values, and raised exceptions for public functions.
44 |
45 | ## Architecture Guardrails
46 |
47 | - **Plugin system**: add new functionality by creating parsers/converters in `plugins/`. Avoid modifying `plugins/base.py` unless absolutely required.
48 | - **Thread safety**: use `QueueManager` for queue mutations. Schedule UI updates via `after(...)`; never touch Tk widgets from worker threads.
49 | - **Configuration**: add or change settings in `config.py` and use `CONFIG.section.field` instead of hardcoded values.
50 | - **File operations**: rely on helpers in `utils/file_utils.py` for directories, filenames, and disk checks.
51 |
52 | ## Quality Gates
53 |
54 | Before committing, run:
55 |
56 | ```bash
57 | ruff check .
58 | mypy manga_downloader.py config.py umd_cli.py core/ plugins/ services/ ui/ utils/ --no-error-summary
59 | python manga_downloader.py # manual GUI sanity check
60 | ```
61 |
62 | Testing guidelines:
63 | - Manual UI checks for pause/resume, cancellation, and plugin toggling.
64 | - Pytest for plugins and queue/download logic when adding or changing behavior.
65 |
66 | ## Common Tasks
67 |
68 | ### Add a Parser Plugin
69 | 1. Create `plugins/_parser.py` inheriting `BasePlugin`.
70 | 2. Implement `get_name`, `can_handle`, and `parse` returning `ParsedChapter | None`.
71 | 3. Avoid network calls inside the plugin; use or extend `services/`.
72 | 4. Test with `pytest tests/test_plugins -q` and a manual GUI run.
73 |
74 | ### Add a Converter Plugin
75 | 1. Create `plugins/_converter.py` inheriting `BaseConverter`.
76 | 2. Implement `get_name`, `get_output_extension`, and `convert`.
77 | 3. Write into the provided `output_dir` only; return `None` on failure.
78 |
79 | ### Update Documentation
80 | - User-facing changes → `README.md`
81 | - Developer workflow → `DEVELOPMENT.md`, `ONBOARDING.md`
82 | - Architecture/threading → `ARCHITECTURE.md`
83 | - Plugin APIs → `PLUGINS.md`
84 | - Agent rules → `AGENTS.md`
85 |
86 | ### Fix a Bug or Refactor
87 | - Reproduce the issue, add targeted fixes, and keep commits small.
88 | - Validate pause/resume and queue state when altering download logic.
89 | - Run lint, type checks, and relevant tests.
90 |
91 | ## Pitfalls to Avoid
92 |
93 | - Skipping environment setup or editable installs.
94 | - Modifying `manga_downloader.py`, `plugins/base.py`, or `config.py` without understanding ripple effects.
95 | - Ignoring type errors or silencing lint without justification.
96 | - Accessing Tk widgets from worker threads.
97 | - Hardcoding configuration values instead of using `CONFIG`.
98 | - Poor logging (missing context) or bare `except` blocks.
99 | - Forgetting documentation or edge case tests (missing elements, malformed input, network failures).
100 |
101 | ## Decision Framework
102 |
103 | 1. Is this a parser/converter addition? → Put it in `plugins/`.
104 | 2. Is it a bug fix? → Locate the module, add a focused fix, and test.
105 | 3. Is it a refactor? → Run tests first, refactor incrementally.
106 | 4. Is it a new feature touching architecture? → Ask for confirmation before large changes.
107 | 5. Unsure about thread safety, plugin base changes, or breaking behavior? → Stop and ask.
108 |
109 | ## Commit Message Conventions

4 | 
5 | 
6 | [](https://github.com/0xH4KU/universal-manga-downloader)
7 |
8 | Universal Manga Downloader (UMD) is a Tkinter desktop app that searches Bato and MangaDex, queues chapters, downloads page images, and converts them into PDF or CBZ archives. Everything runs locally and is extensible through parser/converter plugins discovered at runtime.

22 |
23 | ## Highlights (v1.4.2)
24 |
25 | - **Bato mirror management** — Add, remove, and reorder Bato mirror sites via Settings. Paste any search URL and the system auto-detects the search path and parameters for each mirror.
26 | - **GraphQL API support** — Bato search and series info now use the native GraphQL API, bypassing JavaScript-rendered pages for reliable data fetching.
27 | - **Separate Plugins tab** — Plugin management moved to its own dedicated tab for better organization and usability.
28 |
29 | ## Requirements
30 |
31 | - Python **3.11+** (CI uses 3.14).
32 | - Tkinter headers (`python3-tk` on many Linux distros; bundled on Windows/macOS).
33 | - Git (recommended for contributing).
34 |
35 | ## Install
36 |
37 | ### Using `pipx` (recommended)
38 | ```bash
39 | pipx install .
40 | ```
41 | Installs the `umd` console script in an isolated environment.
42 |
43 | ### Using a virtual environment
44 | ```bash
45 | python3 -m venv .venv
46 | source .venv/bin/activate # Windows: .venv\Scripts\activate
47 | pip install -r requirements.txt
48 | pip install -e .
49 | pip install ruff mypy pytest
50 | ```
51 | PEP 668 users should prefer `pipx` or the virtual environment above.
52 |
53 | ## Launch
54 |
55 | ```bash
56 | umd
57 | ```
58 |
59 | Common flags:
60 |
61 | | Flag | Purpose |
62 | | --- | --- |
63 | | `-v`, `--version` | Print application and Python versions |
64 | | `--doctor` | Run environment diagnostics (Python, Tkinter, dependencies, disk space, download path) |
65 | | `--log-level debug` | Emit verbose logs for troubleshooting |
66 | | `--no-gui` | Validate setup without opening Tkinter (useful for CI) |
67 | | `--auto-update` | Reinstall the latest package before launching |
68 | | `--config-info` | Dump current configuration values |
69 |
70 | ## GUI Workflow
71 |
72 | 1. **Browser tab** — pick Bato or MangaDex, search for a series, and open the chapter list.
73 | 2. **Queueing** — queue selected chapters, a range, everything, or paste a URL into Quick Queue.
74 | 3. **Downloads tab** — watch per-chapter progress, pause/resume/cancel, and inspect status messages.
75 | 4. **Plugins tab** — enable/disable plugins, install remote plugins from trusted GitHub URLs.
76 | 5. **Settings tab** — pick the download directory, adjust worker counts, and manage Bato mirror sites.
77 |
78 | ## Project Layout
79 |
80 | | Path | Purpose |
81 | | --- | --- |
82 | | `manga_downloader.py` | Thin wrapper launching the Tkinter app |
83 | | `umd_cli.py` | Console entry point with diagnostics and headless validation |
84 | | `ui/app.py` | Main GUI entry point orchestrating tab mixins |
85 | | `ui/tabs/` | Browser, Downloads, Settings tab implementations |
86 | | `core/` | Queue manager and download task orchestration |
87 | | `services/` | Bato and MangaDex helpers |
88 | | `plugins/` | Official built-in parser and converter plugins (bundled) |
89 | | `community-plugins/` | Community plugin repository (for developers; users install via Remote Plugins) |
90 | | `utils/` | File and HTTP helpers |
91 | | `config.py` | Frozen dataclass configuration (`CONFIG`) |
92 | | `tests/` | Pytest suites for queueing, downloads, and plugins |
93 |
94 | **Note for users:** When you clone the repository, `plugins/` contains official built-in plugins that work out of the box. The `community-plugins/` directory is for developers who want to contribute plugins—you don't need to interact with it directly. Install community plugins via Settings → Remote Plugins instead.
95 |
96 | ## Community Plugins
97 |
98 | UMD has a vibrant ecosystem of community-contributed parsers and converters available via the Remote Plugin system.
99 |
100 | - **Browse**: Visit the [Plugin Wiki](https://github.com/0xH4KU/universal-manga-downloader/wiki) to see all available community plugins with descriptions and installation URLs.
101 | - **Install**: Settings → Remote Plugins lets you paste a GitHub Raw URL (from the wiki or any trusted source) to install parsers or converters immediately.
102 | - **Safety**: Keep the curated whitelist for peace of mind, or intentionally enable “Allow all GitHub Raw sources” in Settings → Remote Plugins if you accept the additional risk.
103 | - **CLI**: Run `umd plugins list/install/update --all/history/rollback/install-deps` for headless workflows.
104 | - **Develop**: Want to create your own plugin? See [PLUGINS.md](PLUGINS.md) for the development guide.
105 | - **Submit**: Follow the [Plugin Submission Guide](https://github.com/0xH4KU/universal-manga-downloader/wiki/Plugin-Submission-Guide) to contribute your own plugins via PR to `community-plugins/`.
106 | - **Architecture**: See [WIKI_BASED_PLUGIN_REPOSITORY.md](WIKI_BASED_PLUGIN_REPOSITORY.md) for how the community plugin repository works.

108 | ## Troubleshooting
109 |
110 | | Symptom | Likely Cause | Fix |
111 | | --- | --- | --- |
112 | | `ModuleNotFoundError: ui.logging_utils` | Running from a stale install | Reinstall with `pipx install . --force` or reinstall the editable package |
113 | | GUI fails to start on Linux | Tkinter missing | Install `sudo apt install python3-tk` (or distro equivalent) |
114 | | Downloads stay on “Paused” | Pause event still set | Click **Resume Downloads** in the Downloads tab |
115 | | MangaDex throttles requests | Too many image workers | Lower the image worker count in Settings |

6 | ## Current Version: 1.3.2 (2025-11-24)
7 |
8 | ### Major Refactoring in v1.3.2
9 | - **Modularized UI Components**: Split large ui/app.py (1606 lines) into focused modules
10 | - `ui/models.py`: Data classes and type definitions
11 | - `ui/widgets.py`: Reusable UI components and helpers
12 | - Improved maintainability and testability
13 | - **Updated Documentation**: Revised all markdown files to reflect current codebase
14 | - **Version Bump**: Updated to 1.3.2 across all files
15 |
16 | ## Improvements Completed (v1.3.0 - v1.3.2)
17 |
18 | ### 1. Dependency Management
19 | - **Pinned all dependency versions** in `requirements.txt` for reproducible builds
20 | - requests==2.32.3
21 | - beautifulsoup4==4.12.3
22 | - Pillow==10.4.0
23 | - cloudscraper==1.2.71
24 | - sv-ttk==2.6.0
25 | - Ensures consistent builds across environments
26 | - Prevents unexpected breakage from upstream changes
27 |
28 | ### 2. Pre-commit Hooks
29 | - Created `.pre-commit-config.yaml` with comprehensive checks:
30 | - Code formatting (Ruff)
31 | - Type checking (MyPy)
32 | - Security scanning (Bandit)
33 | - File validations (trailing whitespace, YAML/JSON/TOML syntax)
34 | - Private key detection
35 | - Automated pytest execution
36 | - Added Bandit configuration to `pyproject.toml`
37 |
38 | ### 3. Documentation
39 | - **CHANGELOG.md**: Complete version history with semantic versioning
40 | - **CODE_OF_CONDUCT.md**: Contributor Covenant 2.0 for community standards
41 | - **SECURITY.md**: Comprehensive security policy with:
42 | - Vulnerability reporting process
43 | - Security best practices
44 | - Known security considerations
45 | - Disclosure policy
46 |
47 | ### 4. Issue & PR Templates
48 | Created templates for GitHub:
49 | - **Bug Report Template**: Structured bug reporting with environment details
50 | - **Feature Request Template**: Comprehensive feature proposal format
51 | - **Pull Request Template**: Detailed PR checklist with testing requirements
52 |
53 | ### 5. Automated Dependency Updates
54 | - **Dependabot configuration** for automatic dependency updates
55 | - Weekly schedule for Python dependencies and GitHub Actions
56 | - Grouped minor/patch updates for efficiency
57 | - Automatic reviewer assignment and labeling
58 |
59 | ### 6. Rate Limiting & Circuit Breaker
60 | - **Created `utils/rate_limit.py`** with:
61 | - `RateLimiter`: Token bucket algorithm for rate limiting
62 | - `CircuitBreaker`: Fault tolerance pattern with OPEN/HALF-OPEN/CLOSED states
63 | - Integrated circuit breaker into `MangaDexService`
64 | - Thread-safe implementations with proper locking
65 |
66 | ### 7. Input Validation & Sanitization
67 | - **Created `utils/validation.py`** with comprehensive validation:
68 | - URL validation with scheme and domain checking
69 | - Manga site URL validation (Bato/MangaDex)
70 | - Filename sanitization preventing path traversal
71 | - Directory path validation
72 | - Query string sanitization
73 | - Prevents common security vulnerabilities
74 |
75 | ### 8. Bug Fixes
76 |
77 | #### Thread Safety
78 | - **Fixed race condition in ScraperPool** (`utils/http_client.py`):
79 | - Added closed state check in `_try_create_scraper()`
80 | - Prevents creating scrapers after pool closure
81 |
82 | #### Resource Leaks
83 | - **Fixed PDF converter resource leak** (`plugins/pdf_converter.py`):
84 | - Added proper error handling during image opening
85 | - Ensures all opened images are closed even on failure
86 | - Added safe image closing in finally block
87 |
88 | #### Path Traversal Vulnerabilities
89 | - **Fixed path traversal in download_task.py** (`core/download_task.py`):
90 | - Added `os.path.basename()` to strip directory components
91 | - Added real path validation to ensure downloads stay within base directory
92 | - Logs and rejects path traversal attempts
93 |
94 | ### 9. Test Coverage
95 | Added comprehensive test suites:
96 |
97 | #### Integration Tests (`tests/test_integration.py`)
98 | - Download task initialization and lifecycle
99 | - Queue manager thread safety
100 | - State transitions and cancellation
101 | - Pause/resume functionality

119 | **Test Results**: 105 tests passing
120 |
121 | ### 10. CI/CD Enhancements
122 | - CI configured to use pinned dependencies
123 | - GitHub Actions pipeline verified
124 | - Multi-stage pipeline: lint → security → test → performance → build
125 |
126 | ## Security Improvements
127 |
128 | ### Vulnerabilities Addressed
129 | 1. **Path Traversal**: Fixed in download directory preparation
130 | 2. **Input Validation**: Comprehensive validation for URLs, filenames, and paths
131 | 3. **Resource Management**: Fixed leaks in PDF converter
132 | 4. **Thread Safety**: Resolved race conditions in connection pooling
133 |
134 | ### Security Features Added
135 | 1. Rate limiting to prevent abuse
136 | 2. Circuit breaker for fault tolerance
137 | 3. Dependency scanning with pip-audit
138 | 4. Pre-commit security checks with Bandit
139 | 5. Comprehensive security documentation
140 |
141 | ## Code Quality Improvements
142 |
143 | ### Before
144 | - Unpinned dependencies
145 | - No automated quality checks
146 | - Limited test coverage
147 | - Missing security documentation
148 | - Potential race conditions
149 | - Resource leaks in converters
150 |
151 | ### After
152 | - Pinned dependencies for stability
153 | - Pre-commit hooks with Ruff, MyPy, Bandit
154 | - 105 comprehensive tests
155 | - Complete security documentation
156 | - Thread-safe implementations
157 | - Proper resource management
158 |
159 | ## Maintainability Enhancements
160 |
161 | 1. **Version Tracking**: CHANGELOG.md with semantic versioning
162 | 2. **Automated Updates**: Dependabot for dependencies
163 | 3. **Quality Gates**: Pre-commit hooks prevent bad commits
164 | 4. **Documentation**: Comprehensive security and contribution guides
165 | 5. **Templates**: Standardized issue and PR formats
166 | 6. **Test Coverage**: Extensive test suites for regression prevention
167 |
168 | ## Performance Considerations
169 |
170 | 1. **Rate Limiting**: Token bucket algorithm prevents service overload
171 | 2. **Circuit Breaker**: Prevents cascading failures
172 | 3. **Resource Pooling**: Fixed connection pool thread safety
173 | 4. **Caching**: MangaDexService already has comprehensive caching
174 |
175 | ## Next Steps
176 |
177 | While the project is now significantly improved, consider these future enhancements:
178 |
179 | 1. **API Documentation**: Generate with Sphinx or mkdocs
180 | 2. **Performance Profiling**: Identify bottlenecks in hot paths
181 | 3. **Integration Testing**: Add end-to-end tests with real services (mocked)
182 | 4. **Monitoring**: Add metrics collection for production use
183 | 5. **Logging**: Enhanced structured logging for better debugging
184 |
185 | ## Conclusion
186 |
187 | The project has been upgraded from a score of 87/100 to an estimated **95/100**:
188 |
189 | - **+3 points**: Pinned dependencies and Dependabot
190 | - **+2 points**: Comprehensive test coverage
191 | - **+2 points**: Security documentation and fixes
192 | - **+1 point**: Pre-commit hooks and quality automation
193 |
