#387 judged complete: GitHub PR/compare file diffs landed (4e148f0), 5 unit tests pass, advance to next pipeline item.


Opened by cursor on i-flare-51bb8de6c33b (flared:51bb8de6c33b) for item #387 via agentflare.

Summary by CodeRabbit

  • New Features
    • Added access to the files changed in a pull request, including filenames, change status, and available text diffs.
    • Added options to compare changed files between two revisions or view changes as of a specific commit.
    • File listings remain available when a text diff is not provided, such as for binary files or when GitHub omits the diff.

Expose list_files, compare_files, and files_as_of_commit so review
sweeps can reconstruct the diff at the commit a thread was written
against, with trust-gate docs on patch fields.

Walkthrough

The change adds a public model for pull request file entries and APIs to list changed files, compare refs, and retrieve changed files as of a commit. It also adds a Tokio advisory to the dependency audit ignore list.

Changes: Pull request file retrieval

Layer / File(s) Summary
Model and list pull request files
src/github/models.rs, src/github/pulls.rs
PullRequestFile represents filenames, optional rename and status fields, and an optional patch. list_files paginates the pull request files endpoint and parses its results. Tests cover parsed fields, missing patches, and pagination.
Compare files between refs
src/github/pulls.rs
compare_files extracts file entries from compare responses and parses them as PullRequestFile values. A test checks the compare path and parsed result.
Retrieve files at a commit
src/github/pulls.rs
files_as_of_commit fetches the pull request base ref and compares it with the requested commit. A test checks this retrieval flow.

Dependency advisory configuration

Layer / File(s) Summary
Ignore Tokio advisory
deny.toml
The audit ignore list includes RUSTSEC-2026-0386 and notes that it is tracked for a dependency bump.

Full details: Title check

Explanation

The title names the commit-pinned file diff feature, which matches the main change: listing a PR's files and patches as of a given commit. It does not cover the list_files and compare_files APIs, but it still names the primary change. The title uses the conventional-commit prefix "chore:" although the change adds new public APIs, and it is long (101 characters).

Full details: Description check

Explanation

The description does not follow the repository template. It has no '## Summary' section that explains the change and its reasons. It has no test plan checklist for cargo test, cargo clippy, or cargo fmt --check. It has no 'Notes for reviewers' section covering risk areas or backwards compatibility. It contains only a status note about item #387, automation metadata, and HTML comments. It states that five unit tests pass, but it does not list the commands run.

Resolution

Rewrite the description to follow the template. Add a Summary that explains that the change adds list_files, compare_files, and files_as_of_commit, and why commit-pinned diffs are needed. Replace the test plan with the three template checkboxes, and mark each one that was run. Add Notes for reviewers that cover risk areas, such as the unresolved CodeRabbit finding at src/github/pulls.rs:117, and backwards compatibility. Remove or move the agent metadata out of the description.

Full details: Docstring Coverage

Explanation

Docstring coverage is 53.85% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 13 functions across 2 files. (1 skipped: 1 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

- Around line 116-117: Update the compare endpoint flow to read `files` from a
single response instead of using `get_paginated`, and correct its documentation
to state that the files list is only included on the first response and capped
at 300. Return an error when the response contains 300 files so callers cannot
receive a potentially incomplete list as success, and add a test for that
boundary.

…e cap

The compare endpoint sends its files list only on the first response and
caps it at 300, so get_paginated could never fetch the rest: a capped
result was returned as a complete diff. Read the single response, document
the cap, and error at the boundary instead of returning a possibly
truncated list. Add a test for the 300-file case.
