Summary

  • Add a deterministic Triage Radar for the current-attention view proposed in [RFC] Triage radar: surface current attention without managing the backlog #13511.
  • Read recent GitHub issues plus green/approved PR metadata and surface clusters, severe/regression candidates, high-attention reports, and near-finish PR candidates.
  • Refresh only the generated section of [Triage Radar] Current attention candidates #13512 every six hours or on manual dispatch; preserve human-authored text around it.
  • Keep V1 dependency-free: standard-library Python, the normal GitHub token, no new external service or model secret.
  • Fail closed if the configured target issue is missing the [Triage Radar] title prefix or generated-section markers.

Summary by cubic

Adds a scheduled triage radar that deterministically summarizes recent GitHub activity into a categorized feed, refreshed every six hours or on manual dispatch.

  • Reads open issues from the last 72 hours and open, approved, successful-status PRs from the last 168 hours.
  • Clusters related reports by shared title terms, requiring a strong failure-signal term so broad product-area terms, release numbers, or reject-only wording alone don't merge unrelated reports.
  • Flags regression/severe candidates only for bug-labeled issues; confirmed NIGHTLY reproductions are weighted up and fixed-on-NIGHTLY reports down, so meta issues that merely catalog failure terms aren't flagged.
  • Surfaces high-attention issues and lists near-finish PRs.
  • Rewrites only the generated section between HTML markers, preserving human-authored text around it. Fails closed if the target issue is missing the [Triage Radar] title prefix or the markers.
  • Uses only standard-library Python and the normal GitHub token; no new external services or secrets.
  • Fixes a fingerprint test fixture to read the macOS workflow instead of the CI workflow.

Written for commit 256830e. Summary will update on new commits.

Summary by CodeRabbit

  • New Features

    • Added an automated triage radar that periodically updates a designated issue with prioritized open issues, likely regressions, relevant pull requests, and high-attention reports.
    • Related issue reports are grouped into clusters to make recurring problems easier to identify.
    • Triage radar updates can run automatically on a schedule or be triggered manually.
  • Bug Fixes

    • Added safeguards to prevent malformed or unchanged content from overwriting the radar issue.
    • Improved handling of issue signals such as severity indicators, regression evidence, labels, and community activity.

📝 Walkthrough

Walkthrough

The pull request adds a GitHub-backed triage radar script, tests for its analysis and update behavior, and a scheduled workflow that runs it with bounded permissions and serialized execution.

Changes

Triage radar

Layer / File(s) Summary
Issue scoring and clustering
scripts/ci/triage-radar.py
The script normalizes issue data, scores regression evidence, clusters related issues, selects high-attention reports, and applies result limits.
Radar generation and update
scripts/ci/triage-radar.py
The script renders radar sections, validates markers and configuration, queries GitHub, and updates the target issue only when generated content changes.
Workflow wiring and validation

Full details: Docstring Coverage

Explanation

Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 41 functions across 2 files. (1 skipped: 1 unsupported.)

Full details: Cmux Algorithmic Complexity

Explanation

The new production runtime script adds an all-pairs scan in scripts/ci/triage-radar.py:220-223. build_clusters checks every candidate pair and pair_is_clustered rescans both token sets, giving quadratic work. The workflow executes this code, and the GitHub search can supply up to 100 issues (per_page: 100), or about 4,950 pair checks per refresh. The function accepts an unbounded list, and the PR includes no benchmark or measured bound. This violates the rule's nested full-collection scan requirement.

Resolution

Replace the all-pairs loop with an inverted index or token-bucket plan that compares only candidates sharing strong cluster terms and unions groups in one pass. If pairwise matching must remain, enforce a documented small input bound in build_clusters and add a benchmark or measurement that proves the scheduled refresh stays within its budget.

Full details: Cmux Full Internationalization

Explanation

The PR adds a production workflow that writes rendered markdown to GitHub issue #13512. scripts/ci/triage-radar.py hardcodes English headings and messages such as Recent clusters, Regression / severe-path candidates, and No current attention candidates..., then passes the result to update_issue_body. It has no locale-specific source or next-intl integration. This violates the rule for rendered markdown and user-facing data. The supported locale registry is web/i18n/routing.ts, with 20 corresponding files under web/messages/; the PR updates none of them.

Resolution

Move all radar headings, explanatory text, and fallback text into locale-specific message entries. Generate the radar using the selected locale at runtime, or provide the required locale selection and localized issue output. Add matching entries for every locale in web/i18n/routing.ts—en, ja, zh-CN, zh-TW, ko, de, es, fr, it, da, pl, ru, bs, ar, no, pt-BR, th, tr, km, and uk—in the corresponding web/messages/*.json files.

Keep attention separate from regression severity.

A bug-labeled issue with nine comments or reactions gets four points from activity alone and enters Regression / severe-path candidates. build_radar() then excludes it from High-attention recent reports. Remove activity points from regression_evidence(), or require independent risk evidence before select_regressions() accepts the score. Keep attention_count() for high-attention selection and ordering.

To make `304` responses more likely when you poll, keep your requests stable and specific. <title>Resources in the REST API - GitHub Docs</title> https://docs.github.com/enterprise-server@2.22/rest/overview/resources-in-the-rest-api For`POST`,`PATCH`,`PUT`, and`DELETE` requests, parameters not included in the URL should be encoded as JSON with a Content-Type of &`#39`;application/json&`#39`;: ... | Verb | Description | | --- | --- | | `HEAD` | Can be issued against any resource to get just the HTTP header info. | | `GET` | Used for retrieving resources. | | `POST` | Used for creating resources. | | `PATCH` | Used for updating resources with partial JSON data.

In order to provide quality service on GitHub Enterprise Server, additional rate limits may apply to some actions when using the API. For example, using the API to rapidly create content, poll aggressively instead of using webhooks, make multiple concurrent requests, or repeatedly request data that is computationally expensive may result in secondary rate limiting. ... ## Conditional requests ... Most responses return an`ETag` header. Many responses also return a`Last-Modified` header. You can use the values of these headers to make subsequent requests to those resources using the`If-None-Match` and`If-Modified-Since` headers, respectively. If the resource has not changed, the server will return a`304 Not Modified`. ... $ curl -I http(s)://[hostname]/api/v3/user ... > HTTP/2 200 > Cache-Control: private, max-age=60 > ETag: "644b5b0155e6404a9cc4bd9d8b1ae730" > Last-Modified: Thu, 05 Jul ... 2012 15:31:30 GMT > Vary: Accept, Authorization, Cookie > X-RateLimit-Limit: 5000 > X-RateLimit-Remaining: 4996 > X-RateLimit-Reset: 1372700873 ... $ curl -I http(s)://[hostname]/api/v3/user -H &`#39`;If-None-Match: "644b5b0155e6404a9cc4bd9d8b1ae730"&`#39`; > HTTP/2 304 > Cache-Control: private, max-age=60 > ETag: "644b5b0155e6404a9cc4bd9d8b1ae730" > Last-Modified: Thu, 05 Jul 2012 15:31:30 GMT > Vary: Accept, Authorization, Cookie > X-RateLimit-Limit: 5000 > X-RateLimit-Remaining: 4996 > X-RateLimit-Reset: 1372700873 ... $ curl -I http(s)://[hostname]/api/v3/user -H "If-Modified-Since: Thu, 05 Jul 2012 15:31:30 GMT" > HTTP/2 304 > Cache-Control: private, max-age=60 > Last-Modified: Thu, 05 Jul 2012 15:31:30 GMT > Vary: Accept, Authorization, Cookie > X-RateLimit-Limit: 5000 > X-RateLimit-Remaining: 4996 > X-RateLimit-Reset: 1372700873 ... ``` $ curl -I http(s)://[hostname]/api/v3 -H "Origin: http://example.com" -X OPTIONS ...

It still updates the resource even when the ETag is outdated. `gh --version`: ``` gh version 2.18.1 (2022-10-22 Debian 2.18.1+dfsg1-1) https://github.com/cli/cli/releases/tag/v2.18.1 ``` ### Steps to reproduce the behavior ```sh gh api \ -H &`#39`;If-Match: <outdated etag>&`#39`; \ --method PATCH \ https://api.github.com/repos/OWNER/REPO/pulls/PR_NUMBER \ -f body="New PR description" ``` ### Expected vs actual behavior Expected: Returns `gh: HTTP 412` and the PR body is not updated, because the `If-Match` precondition isn&`#39`;t satisfied. Actual behavior: Returned `gh: HTTP 412` but the PR body still got updated to `New PR description`. ### Logs ```sh # Get the original PR body curl -v https://api.github.com/repos/<owner>/<repo>/pulls/4 # Response < HTTP/2 200 < server: GitHub.com < date: Tue, 14 Mar 2023 20:15:19 GMT < content-type: application/json; charset=utf-8 < cache-control: public, max-age=60, s-maxage=60 < vary: Accept, Accept-Encoding, Accept, X-Requested-With < etag: W/"0c8f2fe064ab2ed5be616b585ba6c11410e5893edeee490739b14de8214350da" < last-modified: Tue, 14 Mar 2023 20:15:09 GMT < x-github-media-type: github.v3; format=json < x-github-api-version-selected: 2022-11-28 ... { ...

Do not replace the full issue body after a potentially stale read.

current_body is fetched before updated_body is built. The PATCH then sends the complete body. A human edit between these requests can be overwritten.

GitHub’s Issues API does not document an ETag or version precondition for this PATCH endpoint, so If-Match is not a reliable correction. Store the generated radar content in a dedicated bot-managed issue comment or another compare-and-swap-capable resource. A second GET only narrows the race and cannot guarantee detection.
