* CI: fix buildBody to accept any owner approval, not only the assigned reviewer PR #6446 narrowed the approver lookup to effectiveReviewers (the confirmed- requested subset), inadvertently breaking the case where a non-assigned owner approves. Restore the original intent: any CODEOWNER's approval signs off an area; fall back to effectiveReviewers only when no CODEOWNER is assigned. * text updates * CI: add tests for non-CODEOWNER reviewer sign-off path (#6446) Three tests cover the nonOwnerReviewers fallback introduced in #6446: - pending mention when a non-owner is manually assigned - non-owner approval signs off an area with no CODEOWNER assigned - non-owner approval does NOT sign off when a CODEOWNER was assigned * CI: restore review_requested/review_request_removed triggers These were dropped in #6453 when ready_for_review was added, breaking automatic checklist updates on manual reviewer changes. Both events fall through to the preserve-existing path in coordinateReviewers when a checklist already exists, so the checklist body is simply rebuilt with the current requested_reviewers set. Also extend the opening-race detection (previously called isFirstSyncRace) to cover review_requested: for any PR, CODEOWNERS auto-assignment fires review_requested shortly after opened, and with cancel-in-progress: true that run can cancel the opened run. If no checklist exists yet, treat the review_requested event as a new-PR event and run full selection. * CI: show only one reviewer per checklist area Each area's pending mention now shows the primary (first) effective reviewer rather than all confirmed-requested owners joined with commas. * CI: revert to showing all confirmed reviewers per checklist area A manually added person who is also a CODEOWNER for that area should be shown alongside the load-balanced pick, not hidden. "One reviewer per area" only describes chooseReviewers' default selection, not a display constraint.
What is HDF5?
This repository contains a high-performance library's source code and a file format specification that implements the HDF5® data model. The model has been adopted across many industries, and this implementation has become a de facto data management standard in science, engineering, and research communities worldwide.
The HDF Group is the developer, maintainer, and steward of HDF5 software. Find more information about The HDF Group, the HDF5 Community, and other HDF5 software projects, tools, and services at The HDF Group's website.
