📝 Walkthrough

Walkthrough

Pin many Cargo dependencies to exact versions in Cargo.toml (added gzip feature to reqwest, pinned versions for crates like actix-web, futures, serde, tokio, uuid, etc., and pinned pretty_env_logger); update docker/Dockerfile to add a Cargo dependency-cache build layer, consolidate runtime setup with --no-install-recommends, create a non-root user/home, restore exec bits, and ensure /app/sessions is a volume.

Changes

Cohort / File(s) Summary
Cargo manifest
Cargo.toml
Converted many dependency declarations from ranges to exact pinned versions (e.g., actix-web = "=4.13.0", futures = "=0.3.32", serde = { version = "=1.0.228", features = ["derive"] }, tokio = { version = "=1.50.0", ... }, uuid = { version = "=1.22.0", features = ["v4"] }, etc.). reqwest pinned and gained the gzip feature; pretty_env_logger pinned.
Docker build & runtime
docker/Dockerfile
Introduces a dependency-caching layer by copying Cargo.toml/Cargo.lock and building a dummy src/main.rs, then copying full source for the final build. Consolidates runtime user/group creation and ownership changes in one RUN, uses --no-install-recommends, ensures binary exec bit, creates /home/ygege and /app/sessions, and keeps VOLUME /app/sessions.

Poem

🐇 I pinned the crates, one by one with care,
Gave gzip to requests and cached builds to spare,
Made a cozy home and sessions a nest,
Permissions set right — the build runs at rest,
A rabbit’s nudge: tidy, small, and fair.

Pull request overview

This PR focuses on performance and resource-usage optimizations across search, HTTP usage, magnet generation, and container builds/runtime configuration.

Changes:

  • Share ban_words across parallel searches via Arc to reduce cloning/allocation overhead.
  • Speed up magnet link generation by precomputing the tracker suffix once and pre-sizing the output buffer.
  • Improve runtime/build behavior by introducing static reqwest::Client, Aho–Corasick-based title normalization, Actix response compression, Docker dependency caching, and updated logging/TLS/release settings.

83-88: Remove the unused /app/sessions directory from the Dockerfile.

The application does not implement any session management or session storage. The codebase contains no references to session handling, no session directory operations, and no session-related configuration. The /app/sessions directory created at line 84 is unused and can be safely removed to simplify the image.

75-80: ⚠️ Potential issue | 🔴 Critical

Parse the IMDb /find payload before reading movie fields.

TMDB's /find/{external_id} response nests movie matches under movie_results[]. The code reads id, release_date, original_title, and title from the top-level object, causing DbQueryType::IMDB to fail on valid IMDb IDs instead of producing queries. (Confirmed via developer.themoviedb.org)

171-178: ⚠️ Potential issue | 🟡 Minor

Only strip a standalone sequel suffix.

125-125: Consider moving the keep-alive timeout into config.

Compose healthcheck (compose.yml healthcheck using `curl --fail /health`) to
fail even though `/health` is served by src/rest/infos.rs; restore installation

the compose health probe can execute successfully.
- Around line 40-43: The RUN layer that pre-warms the dependency cache runs
"cargo build --release" but ends the && chain with a semicolon before "rm -rf

the command chain in the RUN instruction so that "cargo build --release" is
joined to the cleanup with && (i.e., ensure the
BUILD_COMMIT/BUILD_DATE/BUILD_BRANCH wrapper and cargo build are followed by &&
rm -rf src) so the layer fails if cargo build fails.

Duration::from_secs(10)) and request timeout (ClientBuilder::timeout, e.g.,

appropriately), and ensure Duration is imported; keep the function signature
http_client() -> &'static Client and only replace Client::new with the

The codebase contains multiple unwrap/expect calls throughout request/relay paths (src/rest/search.rs, src/nostr.rs, src/rate_limiter.rs), meaning a panic in these hot paths will hard-crash the service with no cleanup or recovery mechanism.

Extract TMDB movie ID from /find response before parsing movie fields.

The DbQueryType::IMDB branch calls TMDB's /3/find/{external_id} endpoint, which returns results inside a movie_results[] array; the /3/movie/{id} endpoint exposes id, title, original_title, and release_date at the root level. The parsing code (lines 108–130) assumes the movie-details schema and will fail with "ID not found in TMDB response" for IMDB lookups. Extract the first movie from movie_results[0], recover its TMDB id, and then continue with the existing parsing and alternative-titles flow.

`/3/find/{external_id}` endpoint, extract the first entry from the response's
movie_results array and read its TMDB id, then either set the TMDB id for
downstream parsing or perform a second request to `/3/movie/{tmdb_id}` so the
existing parsing logic (which reads id, title, original_title, release_date and
then fetches alternative titles) can run unchanged; reference DbQueryType::IMDB,
movie_results[0], and the code path that expects root-level movie fields.

Nitpick comments:
In `@src/rest/search.rs`:
- Around line 134-145: Normalize ban_words to lowercase at parsing: when
building the Arc<Vec<String>> assigned to ban_words, map each trimmed word to
its lowercase form (e.g., word.trim().to_lowercase()) so the stored Vec contains
lowercase entries; then remove the per-candidate lowercase calls (the downstream
w.to_lowercase() usage in the candidate filtering code in src/search.rs) so the
algorithm uses the pre-normalized Arc<String>s and avoids repeated allocations.

#!/bin/bash
gh pr edit 215 --repo UwUDev/ygege --body "## Description

This PR introduces a series of performance optimizations targeting search efficiency, memory allocation, HTTP resource usage, magnet link generation, and build pipeline performance.

### Changes

#### 🔍 Title Normalization — Aho–Corasick (`src/dbs.rs`)
- Replaced legacy `FIX_MAP`-based normalization and `ALLOWED_CHARS` filtering with an [Aho–Corasick](https://en.wikipedia.org/wiki/Aho%E2%80%93Corasick_algorithm) automaton (\`fix_ac\`) for efficient multi-pattern replacement.
- Introduced \`FIX_PATTERNS\`, \`FIX_REPLACEMENTS\`, \`fix_title()\`, and a new public \`DbQueryType\` enum (\`TMDB\` / \`IMDB\`) to cleanly select API endpoints.
- Title deduplication now uses a \`HashSet\` during accumulation and a \`push_title\` closure to centralize formatting.

#### 🔗 Shared Static HTTP Client (`src/dbs.rs`)
- Introduced a single shared \`reqwest::Client\` via \`OnceLock\` and an \`http_client()\` helper, replacing per-call \`Client::new()\` instantiations to reduce allocation and connection overhead.
- Extended \`reqwest\` features to include \`gzip\` and \`brotli\` for transparent response decompression.

#### 🧠 Arc-based Shared Ownership for Ban Words (`src/search.rs`, `src/rest/search.rs`)
- Changed \`ban_words\` parameter type from \`Option<Vec<String>>\` to \`Option<Arc<Vec<String>>>\` across \`search()\`, \`batch_best_search()\`, and \`batch_category_search()\` to eliminate redundant clones across async tasks.

#### 🧲 Pre-computed Magnet Tracker Suffix (`src/nostr.rs`)
- Centralized magnet tracker URLs into a \`MAGNET_TRACKERS\` constant.
- Added a \`TRACKER_SUFFIX: OnceLock<String>\` static and \`tracker_suffix()\` helper to build and cache the tracker query string once at runtime, removing repeated string construction per magnet link.
- Magnet link capacity is now pre-computed based on infohash, encoded name, and suffix length.

#### 🐳 Docker Dependency Caching (`docker/Dockerfile`)
- Added a dedicated cache layer: copies \`Cargo.toml\` / \`Cargo.lock\`, builds a minimal placeholder project, then removes it before the real build — allowing Docker layer caching to avoid re-downloading dependencies on source-only changes.
- Consolidated runtime setup (permissions, user/group creation, directory setup) into a single \`RUN\` instruction.
- Switched to \`--no-install-recommends\` for runtime dependency installation.

#### 🌐 Web Server Improvements (`src/main.rs`)
- Enabled HTTP response compression via \`actix_web::middleware::Compress::default()\`.
- Set server keep-alive to 75 seconds via \`Duration::from_secs(75)\`.

#### ⚙️ Miscellaneous
- Added \`panic = \"abort\"\` to \`[profile.release]\` in \`Cargo.toml\` to reduce binary size and eliminate unwinding overhead.
- Replaced \`pretty_env_logger\` with \`env_logger::Builder\` for logging initialization.
- Changed default log level from \`debug\` to \`info\` in \`src/config.rs\`.

---

## Change Type

- [x] Performance improvement
- [x] Refactoring (no functional change)
- [ ] Bug fix
- [ ] New feature
- [ ] Breaking change
- [ ] Documentation update

---

## Testing

- Verified that title normalization produces equivalent results with the Aho–Corasick implementation.
- Shared HTTP client and Arc-wrapped ban words confirmed to work correctly across concurrent search tasks.
- Docker build confirmed to use cached dependency layer on source-only changes.

---

## Migration Notes

- \`search()\` public signature has changed: \`ban_words\` is now \`Option<Arc<Vec<String>>>\`. Callers must wrap their \`Vec<String>\` in \`Arc::new()\`.
- \`pretty_env_logger\` has been removed; \`env_logger\` is now used instead. Log output format may differ slightly.
- Default log level is now \`info\` (previously \`debug\`).

---

## Reviewer Notes

- The Aho–Corasick automaton is initialized once at startup via \`OnceLock\`; no per-request overhead.
- The \`DbQueryType\` enum is public and may be relevant to downstream consumers of \`src/dbs.rs\`.
- The \`panic = \"abort\"\` setting means panics in release builds will not unwind — ensure all \`unwrap()\`/\`expect()\` usages in hot paths are intentional."

83-90: Reconsider baking in /app/sessions as a volume.

I don’t see an in-repo consumer for this path in the provided application entrypoint context, so this turns the container stateful by default without a clear owner. Unless another entrypoint or deployment artifact depends on it, I’d drop the directory/VOLUME or document why it must exist.

Possible simplification
 RUN chmod +x /app/ygege \
-    && mkdir -p /app/sessions \
     && groupadd --gid 10001 --system ygege \
     && useradd --uid 10001 --system --gid ygege --home-dir /home/ygege --shell /sbin/nologin --no-log-init ygege \
     && mkdir -p /home/ygege \
     && chown -R ygege:ygege /app /home/ygege

Add .dockerignore to prevent build context bloat and preserve cache benefits.

The dependency-cache split requires a root .dockerignore that excludes target/, .git/, .cargo/, and other build artifacts. Without it, COPY . . will re-copy all local files on every build, invalidating the cached dependency layer and defeating the optimization.

Create .dockerignore with at least:

target/
.git/
.gitignore
.cargo/
