Review Change Stack

Warning

Review limit reached

@mmengelkoch-fa, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 46 minutes

Limit details: You’ve used all 1 included review currently available under your plan.

You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

📝 Walkthrough

Walkthrough

The PR replaces unverified prebuilt downloads with checksum-pinned, cached, and atomically installed artifacts. It adds release upload verification, GitHub Actions integration, documentation, and crate version updates.

Changes

Prebuilt library distribution

Layer / File(s) Summary
Artifact contracts and source resolution
xgboost-sys/Cargo.toml, xgboost-sys/build.rs, README.md
The build uses platform-specific artifact metadata, SHA-256 pins, ordered sources, configurable mirrors, persistent caches, and offline settings.
Verified artifact provisioning and installation
xgboost-sys/build.rs
Existing files are validated, downloads use retries and size limits, and verified artifacts are installed atomically. macOS libraries receive install-name rewriting and ad-hoc signing.
Release asset staging and workflow verification
scripts/upload-release-libs.sh, .github/workflows/prebuilt-libs.yml
The script stages and verifies release assets. The workflow runs dry-run checks and conditional uploads for releases or manual dispatches.
Version metadata updates
Cargo.toml, xgboost-sys/Cargo.toml
The crate versions and the xgboost-sys dependency requirement are incremented.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟠 High · up to 9c761

The PR changes artifact resolution and adds a release-upload workflow. Cached libraries can be accepted without matching the pinned checksum, and a manually supplied release tag is inserted into a write-enabled shell command, risking unintended binaries or compromise of the release job. The PR is not merge-ready until these issues are fixed.

419-430: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

with_extension replaces the existing extension, so different artifacts share one temporary name.

For win_amd64 the artifacts are xgboost.dll and xgboost.lib. Both produce the temporary path xgboost.tmp<pid>. The current loop installs them one after the other, so no collision occurs today. Two concurrent processes get different pids. Appending the suffix instead of replacing the extension removes the hazard and keeps the original name visible in the temporary file.

🛡️ Proposed change
-    let tmp = dest.with_extension(format!("tmp{}", std::process::id()));
+    let mut tmp = dest.as_os_str().to_os_string();
+    tmp.push(format!(".tmp{}", std::process::id()));
+    let tmp = PathBuf::from(tmp);

Derive the mirror URLs from LIB_TAG.

LIB_TAG is "v3.0.5", and both mirror entries repeat the same literal. A future tag bump must then be applied in three places, and a missed edit points the mirrors at the wrong bytes while the checksums stay pinned to the new tag. concat! keeps the values in one place.

♻️ Proposed refactor
 #[cfg(feature = "use_prebuilt_xgb")]
 const MIRRORS: &[&str] = &[
-    "https://github.com/marcomq/rust-xgboost/raw/refs/tags/v3.0.5/xgboost-sys/lib",
-    "https://github.com/marcomq/rust-xgboost/releases/download/v3.0.5",
+    concat!("https://github.com/marcomq/rust-xgboost/raw/refs/tags/", "v3.0.5", "/xgboost-sys/lib"),
+    concat!("https://github.com/marcomq/rust-xgboost/releases/download/", "v3.0.5"),
 ];

concat! requires literals, so keep the tag literal in one macro_rules!-free constant such as const LIB_TAG_LIT: &str = "v3.0.5"; used by both LIB_TAG and the concat! calls, or build the URLs at run time in mirror_bases() with format!("{...}/{LIB_TAG}").

Inline comments:
In @.github/workflows/prebuilt-libs.yml:
- Around line 47-50: Update the “Upload and verify release assets” step to pass
inputs.tag through an environment variable, then invoke upload-release-libs.sh
using a quoted shell expansion of that variable. Preserve the existing
empty-value behavior so release events continue allowing the script’s LIB_TAG
fallback.

In `@README.md`:
- Around line 113-138: Update the resolver documentation near the source-order
list to include the existing target/.../deps artifact check before the cache
lookup, and document that download URLs using a base containing
/releases/download/ use the base/platform-file layout instead of
base/platform/file. Add the appropriate language identifier to the
environment-variable code fence.

Apply the same fix in `@README.md` around lines 129 - 131.

In `@scripts/upload-release-libs.sh`:
- Around line 145-160: Update the verification loop around sha256_of to retry
each release-asset download a bounded number of times before marking it failed,
allowing transient network or propagation errors to recover. Retain the existing
SHA-256 comparison and mismatch reporting, and only set failed after all
download attempts fail or the downloaded content remains mismatched.

In `@xgboost-sys/build.rs`:
- Around line 226-245: Update install_artifact and all three call sites,
including provide_artifact and the call sites near the existing artifact
handling branches, so the stamp records both the expected artifact.sha256 and
the installed file hash. Require both values to match before accepting a stamped
destination, ensuring stale artifacts from previous pins are rejected while
preserving post-install hash validation.
