Alex 4472fbe8cf Download overhaul - DNS fallback, bypasser enhancements, revamped error handling, better frontend UX (#336)
## Changelog

### 🌐 Network Resilience

- **Auto DNS rotation**: New `CUSTOM_DNS=auto` mode (now default) starts
with system DNS and automatically rotates through Cloudflare, Google,
Quad9, and OpenDNS when failures are detected. DNS results are cached to
improve performance.
- **Mirror failover**: Anna's Archive requests automatically fail over
between mirrors (.org, .se, .li) when one is unreachable
- **Round-robin source distribution**: Concurrent downloads are
distributed across different AA partner servers to avoid rate limiting

### 📥 Download Reliability

- **Much more reliable downloads**: Improved parsing of Anna's Archive
pages, smarter source prioritization, and better retry logic with
exponential backoff
- **Download resume support**: Interrupted downloads can now resume from
where they left off (if the server supports Range requests)
- **Cookie sharing**: Cloudflare bypass cookies are extracted and shared
with subsequent requests, often avoiding the need for re-bypass entirely
- **Stall detection**: Downloads with no progress for 5 minutes are
automatically cancelled and retried
- **Staggered concurrent downloads**: Small delays between starting
concurrent downloads to avoid hitting rate limits
- **Source failure tracking**: After multiple failures from the same
source type (e.g., Libgen), that source is temporarily skipped
- **Lazy welib loading**: Welib sources are fetched as a fallback only
when primary sources fail (unless `PRIORITIZE_WELIB` is enabled)

### 🛡️ Cloudflare & Protection Bypass

- **DDOS-Guard support**: Internal bypasser now detects and handles
DDOS-Guard challenges with dedicated bypass strategies
- **Cancellation support**: Bypass operations can now be cancelled
mid-operation when user cancels a download
- **Smart warmup**: Chrome driver is pre-warmed when first client
connects (controlled by `BYPASS_WARMUP_ON_CONNECT` env var) and shuts
down after periods of inactivity

### 🔌 External Bypasser (FlareSolverr)

- **Improved resilience**: Retry with exponential backoff, mirror/DNS
rotation on failure, and proper timeout handling
- **Cancellation support**: External bypasser operations respect
cancellation flags

### 🖥️ Web UI Improvements

- **Simplified download status**: Removed intermediate states
(bypassing, verifying, ingesting) — now just shows Queued → Resolving →
Downloading → Complete
- **Status messages**: Downloads show detailed status like "Trying
Anna's Archive (Server 3)" or "Server busy, trying next...", or live
waitlist countdowns.
- **Improved download sidebar**:
  - Downloads sorted by add time (newest first)
  - X button moved to top-right corner for better UX
  - Wave animation on in-progress items
  - Error messages shown directly on failed items
  - X button on completed/errored items clears them from the list

### ⚙️ Configuration Changes

- **`CUSTOM_DNS=auto`** is now the default (previously empty/system DNS)
- **`DOWNLOAD_PROGRESS_UPDATE_INTERVAL`** default changed from 5s to 1s
for smoother progress
- **`BYPASS_WARMUP_ON_CONNECT`** (default: true) — warm up Chrome when
first client connects

### 🐛 Bug Fixes

- **Download cancellation actually works**: Fixed issue where cancelling
downloads didn't properly stop in-progress operations
- **WELIB prioritization**: Fixed `PRIORITIZE_WELIB` not being respected
- **File exists handling**: Downloads to same filename now get `_1`,
`_2` suffix instead of overwriting
- **Empty search results**: "No books found" now returns empty list
instead of throwing exception
- **Search unavailable error**: Network/mirror failures during search
now return proper 503 error to client

Alex 122a3633c2 APP_ENV removal and secure cookie handling (#333)
Hey, made the tweaks we discussed, plus a couple related fixes :)

- Removed APP_ENV entirely. All dev-specific functionality is enabled
via `DEBUG: true` env var
- Set secure cookie handling to false by default, added to the readme to
enable if exclusively using HTTPS connection
- Fixed healthcheck potentially not working with auth enabled
- Removed APP_ENV from docker compose files and made sure app.db lines
are included in all versions.

APP_ENV in people's existing composes should get ignored entirely and
will be put on the default env, so no issues when updating.

2b831dcfa5 [FEATURE] Separate download folders #122 (#297)
Re: Issue #122
Fetches content type from search results - displays it on thumbnails in
results grid;
Fetches content type from book id detail page (dfaults to "Other") and
uses it to construct the `final_path`.

Stephon ParkerandCaliBrain 5e04b6bfb8 Add Download Queue Management & Concurrent Downloads (#231)
## Summary

This PR completely overhauls the download system to support concurrent
downloads, cancellation, and advanced queue
management. No more waiting for stuck downloads to block the entire
queue!

  ## New Features

  ###  **Concurrent Downloads**
  - **3 simultaneous downloads** by default (configurable)
- ThreadPoolExecutor-based architecture replaces single-threaded
bottleneck
  - Downloads no longer block each other

  ###  **Download Cancellation**
  - **Cancel button** for active/queued downloads
  - Clean cancellation with partial file cleanup
  - Thread-safe cancellation flags

  ### **Queue Priority & Reordering**
  - **Priority-based queue** (lower number = higher priority)
  - **Editable priority inputs** in UI for queued items
  - **Bulk reordering** API support

  ## UI Enhancements

- **Enhanced status table** with Priority, Progress, and Actions columns
  - **Progress bars** for active downloads
  - **Cancel buttons** for downloads
- **Queue management controls**: Refresh, Clear Completed, Active
Counter
  - **Real-time updates** every 60 seconds

## Implementation

  ### New Architecture
  - `queue.PriorityQueue` replaces simple `set()` for proper ordering
  - `concurrent.futures.ThreadPoolExecutor` handles worker threads
  - `threading.Event` flags enable clean cancellation
  - Thread-safe operations with proper locking

  ### New API Endpoints
  DELETE /api/download/{id}/cancel     # Cancel downloads
PUT /api/queue/{id}/priority # Set priorityPOST /api/queue/reorder #
Bulk reorder
  GET /api/downloads/active          # Active tracking
  DELETE /api/queue/clear            # Clear completed

  ### New Environment Variables
  ```bash
  MAX_CONCURRENT_DOWNLOADS=3          # Worker thread count
  DOWNLOAD_PROGRESS_UPDATE_INTERVAL=5  # Progress frequency
  ```

### Fully backward compatible - existing functionality unchanged

### Fixes

  - Resolves: Downloads blocking when one gets stuck
  - Resolves: No way to cancel problematic downloads
  - Resolves: No queue management or prioritization

Timothy Allen 086401083e Add simple authentication (#181)
This commit adds user authentication, using Calibre-Web's app.db as its
authentication source, as requested in #56. It uses @prinzpi's
[comment](https://github.com/calibrain/calibre-web-automated-book-downloader/issues/56#issuecomment-2919335169)
as a starting point, but integrates the logic directly into the app.

This requires the user to specify the environment variable CONFIG_ROOT,
set to Calibre-Web's config directory (the directory that contains the
app.db database that holds the user's authentication information).

If the user does not wish to add authentication, they can simply leave
CONFIG_ROOT unset, or not pointing at Calibre-Web's app.db directory.

CaliBrain 57f15b4d95 Tor support, use SeleniumBase instead of DrissionPage (#123)
Refactor: Improve Docker build, add Tor support, use SeleniumBase

- Overhauled Dockerfile:
    - Switched to python:3.10-slim base.
    - Implemented multi-stage builds (base, standard, tor).
    - Consolidated RUN layers for efficiency.
    - Added locale/timezone setup.
- Added Tor setup and iptables configuration in dedicated stage/script.
- Replaced DrissionPage with SeleniumBase for Cloudflare bypassing.
- Added Tor support via `docker-compose.tor.yml` and `tor.sh` script.
- Updated `docker-compose.yml` to build locally and changed default port
to 8083.
- Added `docker-compose.dev.yml` and `docker-compose.tor.dev.yml`.
- Updated `entrypoint.sh` for timezone and sudo usage.
- Added/Updated environment variables (`TZ`, `USING_TOR`, etc.).
- Improved `.dockerignore`.
- Updated `readme.md` to reflect port changes, build process, document
`TZ`, and add details about the new Tor variant.
