Summary of Changes

Hello @chipp, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request focuses on a comprehensive optimization of the project's dependency graph and tokio runtime feature usage. The primary goal is to enhance build efficiency and reduce the overall footprint by eliminating unneeded crates and precisely configuring tokio features. Additionally, a significant upgrade to the zip compression library has been performed, bringing in updated compression-related dependencies.

Highlights

  • Dependency Removal: Several unused or redundant crates, including 'bytes', 'futures', 'md5', 'serde', and 'tokio-stream', have been removed from various Cargo.toml files and the Cargo.lock file, streamlining the project's dependencies.
  • Tokio Feature Optimization: The feature set for the tokio crate has been fine-tuned across multiple binaries and libraries. Unnecessary features such as 'io-util', 'net', 'signal', 'macros', 'rt-multi-thread', and 'time' have been removed where they were not explicitly required, aiming to reduce binary size and improve compilation times.
  • Zip Crate Upgrade: The zip crate has been upgraded from version 2.6 to 3.0. This upgrade also involved adding libz-rs-sys and zlib-rs as new dependencies in Cargo.lock and removing crossbeam-utils from zip's internal dependencies.
  • Hashbrown Version Consolidation: The Cargo.lock file was cleaned up to remove an older hashbrown version (0.14.5) and simplify dependency declarations to consistently use the newer 0.15.2 version.
  • Signal Handling Refinement: In bin/elisheba/src/main.rs, the explicit SIGTERM handling logic using tokio::signal::unix has been removed, simplifying the application's shutdown mechanism.

Code Review

This pull request effectively optimizes dependencies by removing unused crates and features. This is a positive change for build times and binary sizes. However, there is a critical regression in the elisheba service where graceful shutdown handling has been removed. I've also highlighted a major dependency upgrade for the zip crate that warrants careful testing for breaking changes. Please review the specific comments for details.


futures-util = "0.3"
tokio = { version = "1", features = ["macros", "rt-multi-thread", "net", "signal", "sync"] }

critical

Removing the signal feature from tokio is problematic as it breaks the graceful shutdown functionality in src/main.rs. Please re-add the signal feature. It's also advisable to keep the net and sync features for a networked, multi-threaded application like this to avoid potential issues.

tokio = { version = "1", features = ["macros", "rt-multi-thread", "time"] }

critical

The graceful shutdown logic has been removed. As try_join will block indefinitely, the process can no longer be stopped gracefully via SIGTERM. This is a critical regression. After restoring the signal feature in Cargo.toml, please re-implement the graceful shutdown mechanism here, for example by replacing this line with a tokio::select! block that waits for either the tasks to complete or for a shutdown signal.

high

The zip crate has been upgraded from version 2.6 to 3.0. This is a major version bump, which often indicates breaking changes. According to the zip crate's changelog, version 3.0 is a rewrite with a focus on streaming support. Please ensure that this upgrade has been thoroughly tested to confirm there are no regressions or unexpected behavior.
