v4.2.25

  • Fixed a whitelist with persistent = false not being loaded at startup (regression in v4.2.24). v4.2.24 loaded a list only when its table was persistent, so a read-only whitelist, such as one pointed at the website's torrents table with persistent = false, came up empty. With whitelist_enabled on, every announce for a torrent not added over the API since the restart got unknown info_hash, and since those refusals are not counted as failures, the only sign was the seed and peer counts dropping. A list is loaded again whenever its mode is on, as before v4.2.24, and also when its table is persistent; persistent = false only stops it being written back.
  • Peer expiry no longer rewrites every idle torrent on every pass (regression in v4.2.24). With persistent on, a torrent without announces for longer than the peer timeout stays expired, and each cleanup pass queued it again even when it had no peers left to remove. Every torrent loaded from the database was written to the database and to the cache every peers_cleanup_interval, and Redis kept a zero-count key for each one. A torrent is now queued only when the pass actually removed peers from it.

Summary by CodeRabbit

  • Bug Fixes

    • Startup now correctly loads whitelist, blacklist, key, and user data when persistence is configured, including persistent tables whose corresponding feature is disabled.
    • Prevented idle torrents and empty cache entries from being repeatedly rewritten during peer cleanup.
    • Improved cleanup update handling to avoid overwriting newer torrent activity.
  • Documentation

    • Added release notes covering persistence behavior, startup warnings, and recent API and library changes.

📝 Walkthrough

Startup list loading now considers persistence settings. Torrent cleanup avoids requeueing unchanged torrents. Benchmarks use shared helpers. Release metadata, dependencies, and runtime configuration were updated for version 4.2.25.

Changes: Tracker behavior

Layer / File(s) Summary
Startup list loading
src/tracker/impls/torrent_tracker_torrents_updates.rs, src/main.rs, tests/database_tests.rs
TorrentTracker::load_lists loads lists based on global persistence, table persistence, and enabled modes. Startup calls this method. The SQLite test covers whitelist loading combinations.
Cleanup update queuing
src/tracker/impls/torrent_sharding.rs, tests/tracker_tests.rs, README.md
Cleanup queues persistent torrent updates only when it removes peers and queues them while holding the shard write lock. The test checks that empty torrents are not requeued.

Benchmark helper reuse

Layer / File(s) Summary
Shared benchmark setup
benches/tracker_benchmarks.rs
Benchmark cases use shared helpers to construct trackers and generate peers, hashes, identifiers, and addresses. Existing benchmark scenarios remain unchanged.

Release configuration and metadata

Layer / File(s) Summary
Release configuration and metadata
Cargo.toml, config.toml, docker/build.bat, src/openapi.json, README.md
Version metadata changed to 4.2.25. Four dependencies were removed. Runtime configuration and release notes were added or updated.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~20 minutes

Change: Bug fix

Merge Risk: 🟡 Moderate · up to 15865

Whitelist mode still fails to load a read-only whitelist when database persistence is turned off, so whitelisted torrents can be rejected. The new sample config.toml also ships a publicly known API key on a public listener, which applies to anyone who runs the tracker from a checkout. Fix the whitelist loading condition and remove or replace the committed key before merging.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Load enabled read-only lists when global persistence is off.

If [database] persistent = false and the whitelist table has persistent = false, wanted returns false even when whitelist_enabled = true. Startup then leaves a prepopulated read-only whitelist unloaded, so its torrents fail whitelist checks. Let the enabled mode request a read independently of write-back settings, and cover this configuration in the integration test.

Proposed change
-        let wanted = |enabled: bool, table: Option<bool>| (persistent && enabled) || table.unwrap_or(persistent);
+        let wanted = |enabled: bool, table: Option<bool>| enabled || table.unwrap_or(persistent);
📝 Committable suggestion

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Suggested change
let wanted = |enabled: bool, table: Option<bool>| (persistent && enabled) || table.unwrap_or(persistent);
let wanted = |enabled: bool, table: Option<bool>| enabled || table.unwrap_or(persistent);

Do not commit a shared API key in the default configuration.

When the application starts from a checkout containing this file, Configuration::load_from_file replaces the generated key with this committed value. The enabled API listener then binds to 0.0.0.0:8081, so anyone who knows the repository can authenticate to the protected API.

This is not a Docker-image exposure because Docker excludes config.toml and Docker Compose requires TRACKER__API_KEY. Remove this file from the default deployment path, or make users generate and provide a unique key with --create-config or TRACKER__API_KEY. Rotate this key wherever it has been used.
